Steller sea lion. The Steller sea lion (Eumetopias jubatus), also known as the Steller's sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus "Eumetopias" and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers.

Steller sea lion. over an extensive portion of their northern range in Alaska.## Description.Adult animals are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around 23 (kg), and remain dark in coloration for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably. Adult females measure 2.3 - 2.9 (m) in length, on average being 2.5 (m), and weigh 240 - 350 (kg), with an average of 263 (kg). Males continue to grow until their secondary sexual traits.

Steller sea lion. appear in their fifth to eighth year. Males are slightly longer than the females, growing to about 2.82 – 3.25 (m) long and averaging 3 (m) in length. Males have much wider chests, necks, and general forebody structure. Males can weigh between 450 – 1120 (kg), weighing on average 544 (kg). Males are further distinguished from females by broader and higher foreheads, flatter snouts, and a thick mane of coarse hair around their large necks. It is fitting then that their Latin name translates roughly as "maned one with the broad forehead".## Range.The range of the Steller sea lion extends.

Steller sea lion. from the Kuril Islands in the Sea of Okhotsk in Russia to the Gulf of Alaska in the north, down to Año Nuevo Island off the coast of central California to the south. They formerly bred as far south as the Channel Islands, but have not been observed there since the 1980s. Based on genetic anаlyses and local migration patterns, the global Steller sea lion population has traditionally been divided into an eastern and western stock at 144°W longitude, roughly through the middle of the Gulf of Alaska. Recent evidence suggests the sea lions in Russia in the Sea of.

Steller sea lion. Okhotsk and the Kuril Islands comprise a third Asian stock, while the sea lions on the eastern seaboard of Kamchatka and the Commander Islands belong to the western stock.In the summer, Steller sea lions tend to shift their range somewhat southward. Therefore, though there are no reproductive rookeries in Japan, several consistent haul-out sites are found around Hokkaidō in the winter and spring. Vagrants have been spotted in the Yellow Sea and Bohai Gulf and along the coast of Korea and China. The oldest fossil known of the species was found near Kanazawa, Japan and dates to the late Early.

Steller sea lion. Pleistocene (0.8 Ma).## Ecology.## Habitat.Steller sea lions tend to live in the coastal waters of the subarctic because of the cooler temperate climate of the area. Like all otariids, Steller sea lions are amphibious and spend some time in water and some on land. Typically, Stellar sea lions spend their time in the water feeding but haul-out onto land to reproduce, raise their pups, molt, and rest. Steller sea lions usually congregate on isolated islands because they are the ideal terrestrial habitat. These isolated islands are preferred by Stellar sea lions because they can avoid predation from terrestrial predators, easily.

Steller sea lion. thermoregulate (by means of cooling winds), and access offshore prey more easily. Some haul-out sites, known as rookeries, are commonly used for reproduction while other haul-out sites are used for other purposes like molting. However, both biotic and abiotic factors can influence the amount of time that Steller sea lions spend on land. Haul-out sites and haul-out abundance of the Steller sea lion can be determined by prey availability, predator abundance, tide levels, weather, etc.## Foraging.Steller sea lions are skilled and opportunistic marine predators, feeding on a wide range of fish and cephalopod species. Important diet components include walleye pollock,.

Steller sea lion. Atka mackerel, halibut, herring, capelin, flatfish Pacific cod, rockfish, sculpins, salmon, sand lance, and cephalopods such as various squid and octopus. They seem to prefer schooling fish and forage primarily between intertidal zones and continental shelves. They usually aggregate in groups of up to twelve in areas of prey abundance. They are known to aggregate near fishing vessels, preying on bycatch discards. Most of the data on their foraging comes from data collected off the coast of Alaska; little is known of their foraging behavior elsewhere.The composition of the diet of Steller sea lions varies seasonally and geographically; as opportunistic.

Steller sea lion. predators, they concentrate on the locally most abundant prey species. In addition to their primary marine environment, they sometimes enter estuaries and feed on brackish-water fish such as sturgeon. Very occasionally, they have been known to prey on northern fur seals, harbor seals, and sea otter pups. Records suggest that the range of their prey species has broadened over time.## Predation.Steller sea lions are top-tier carnivores, but are susceptible to predation, primarily by killer whales. Shark species are also possible predators: sleepers and great whites may prey on juvenile sea lions.## Behavior and life history.## Reproduction.Reproductively mature male sea lions.

Steller sea lion. gather together mid-spring on traditional, well-defined reproductive rookeries, usually on beaches on isolated islands. The larger, older males establish and defend distinct territories on the rookery. A week or so later, adult females arrive, accompanied occasionally by sexually immature offspring, and form fluid aggregations throughout the rookery. Like all other otariids, Steller sea lions are polygynous. However, unlike some other species, they do not coerce individual females into harems, but control spatial territories among which females freely move. Steller sea lions have used aquatic, semiaquatic, and terrestrial territories. Males with semiaquatic territories have the most success in defending them. The.

Steller sea lion. boundaries are defined by natural features, such as rocks, faults, or ridges in rocks, and territories can remain stable for 60 days. Though Steller sea lion males are generally tolerant of pups, one male filmed on Medny Island in Russia was documented killing and eating several pups in a first-ever recorded incident of cannibalism. Though researchers are uncertain as to the motives or reasons behind said attacks, it is suggested that the bull involved may have an abnormal personality akin to being psychotic.Pregnant females give birth soon after arriving on a rookery, and copulation generally occurs one to two weeks.

Steller sea lion. after giving birth, but the fertilized egg does not become implanted in the uterus until the fall. A fertilized egg may remain in embryonic diapause for up to three months before implanting and beginning to divide. Twins are rare. After a week or so of nursing without leaving the rookery, females begin to take progressively longer and more frequent foraging trips leaving their pups behind until at some point in late summer, when both the mother and pup leave the rookery together. This maternal attendance pattern is common in otariids. As pups get older the amount of time spent by.

Steller sea lion. females foraging out at sea increases. This continues until pups obtain the ideal body weight and energy reserves to eat on their own. A study conducted by the University of California, Santa Cruz found that on average male pups consume more milk than females. This may be due to the sexual dimorphism common to otariids. Reproductive males fast throughout the reproductive season, often without entering the water once from mid-May until August, when the structure of the reproductive rookeries begins to fall apart and most animals leave for the open seas and disperse throughout their range.The age at weaning is.

Steller sea lion. highly variable; pups may remain with their mothers for as long as four years. Incidents of mothers feeding daughters that are simultaneously feeding their own newborn pups have been documented, which is an extremely rare occurrence among mammals. A study done at Año Nuevo in 1983 found that female attendance and time spent with their pup was shaped by increasing nutritional demands of the pup and the pups suckling efficiency. Females averaged 21 hours ashore and 36 hours at sea. As the pups aged, females began to spend more time at sea again. As the pups matured, specifically at the.

Steller sea lion. sixth week past birth, the mother's sea time declined by 30 percent. There was no relationship between the pups' activity or physical excursion and their suckling time, age, or sex. Their suckling time, and age, and sex are unrelated to their use of energy. Labeled water studies showed that the pups' milk intake had a direct relationship to their size. Pups that consumed more milk were heavier than those that didn't. These findings show that the amount of time females spend onshore with their pups is based on their pup's suckling efficiency and nutritional demands.In the past, the low pup.

Steller sea lion. production has been tied to an increase in nutritional stress found in females. This was believed to have contributed to the decline in Steller sea lions common to Alaska.## Locomotion.The largest of the eared seals, Steller sea lions are quick swimmers, about as fast as the smaller California sea lions. Glide velocity of individual Steller sea lions has been measured as 2.9–3.4 meters or 1.2–1.5 body lengths per second, which is close to the optimal swim velocity of 1.4 body lengths per second based on the minimum cost of transport for California sea lions.A 2007 study of Steller sea lions.

Steller sea lion. found that a majority of thrust was produced during the drive phase of the fore flipper stroke cycle. Although previous findings on eared seals suggested that thrust was generated by the initial outward movement of the foreflippers or the terminal drag-based paddling phase, the 2007 study found that little or no thrust was generated during those phases. Swimming performance in sea lions is modulated by changes in the duration and intensity of movements without changing their sequence. Using criteria based on velocity and the minimum radius of turns, Steller's maneuverability is similar to other eared seals, superior to cetaceans, and.

Steller sea lion. inferior to many fish.## Diving.To be able to dive for a long period of time, Steller sea lions exhibit apnea, bradycardia, and peripheral vasoconstriction. This allows them to maximize their oxygen stores and efficiently forage during their dives. In addition to those adaptations, their thick blubber layer and outer fur layer keep their body insulated during dives.Trained Steller sea lions from Vancouver Aquarium were placed in the open ocean at the University of British Columbia's Open Water Research Station to study their diving metabolism and behavior. Steller sea lions' dives are more energetically costly if they perform dive bouts. The.

Steller sea lion. aerobic diving limit of Steller sea lions was observed to be affected by their nutritional state and feeding.## Communication.Like most otariids, Steller sea lions are vocal in air. Mature male sea lions have a range of vocalizations as part of their territorial behaviors, including belches, growls, snorts, and hisses that serve as warnings to others. Both males and females also produce underwater noises similar to their above water sounds, described as clicks, barks, and belches. The primary function of their vocalizations is for social behavior. Sonogram readings reported that Steller Sea Lions make discrete, low frequency pulses underwater that resemble.

Steller sea lion. the male "belching" territorial noise made in air. These underwater vocalizations have an average of 20–30 pulses per second.Vocalizations are critical to mother-pup pairs, as the mothers must find their pups in a crowded breeding area when they return from foraging. The mother and pup both use distinctive calls, like names, to help differentiate themselves among the crowd of other sea lions. Their aerial vocalizations have been described as similar to the bleats of sheep, and bellows.Because Steller sea lions are sexually dimorphic in size, their hearing differs in sensitivity, possibly due to differences in size of the hearing structures.

Steller sea lion. Females have a higher sensitivity than males, perhaps to hear the higher frequency calls of their pups. The Steller sea lion's hearing range also suggests that they are capable of hearing the underwater calls of one of their main predators, the killer whale.## Interactions with humans.Steller sea lion were hunted for meat and other commodities by prehistoric communities everywhere their range intersected with human communities. Aside from food and clothing, their skin was used to cover baidarkas and kayaks. A subsistence harvest on the order of 300 animals or less continues to this day in some native communities in Alaska.Historically,.

Steller sea lion. the sea lion has had only very slight commercial value. For example, in the 19th century their whiskers sold for a penny apiece for use as tobacco-pipe cleaners.Steller sea lions are sometimes killed intentionally by fishermen, as they are seen as competitors and a threat to fish stocks. Killing sea lions is strictly prohibited in the US and Russia, but in Japan a fixed number are still removed annually, ostensibly to protect their fisheries. In Canada, commercial hunting is prohibited, but limited hunting permits are occasionally granted if local culling is required—for example, nuisance animals destroying fish farms.In recent years,.

Steller sea lion. Steller sea lions have been known to enter the Columbia River estuary and feed on white sturgeon, several salmon species, and rainbow trout, some of which are also listed under the U.S. Endangered Species Act. They are found in the Columbia River nearly year round, with the exception of early summer, going as far upstream as Bonneville Dam. Though not as abundant as the California sea lion, they are still a concern for those agencies charged with managing the fish populations. Since the Steller sea lions are themselves protected under the Marine Mammal Protection Act, managers are compelled to use.

Steller sea lion. nonlethal deterrence methods, such as rubber bullets and noisemakers. Deterrence by the public is strictly forbidden.## Recent decline and subsequent recovery.While the populations of the eastern and Asian stocks appear stable, the population of the western stock, particularly along the Aleutian Islands, was estimated to have fallen by 70–80% since the 1970s. As a consequence, in 1997 the western stock of Steller sea lions was listed as endangered and the eastern stock was listed as threatened under the United States Endangered Species Act. They have since been the object of intense study and the focus of much political and scientific.

Steller sea lion. debate in Alaska.One suspected cause of their precipitous decline was the overfishing of Alaska pollock, herring, and other fish stocks in the Gulf of Alaska. This stems largely from the "junk-food hypothesis" representing a shift in their diet from fatty herring and capelin to leaner fare such as pollock and flounder, thereby limiting their ability to consume and store fat. Other hypotheses include increased predation by orcas and sharks, indirect effects of prey species composition shifts due to changes in climate, effects of disease or contaminants, shooting by fishermen, and others. The decline is certainly due to a complex of.

Steller sea lion. interrelated factors which have yet to be defined by the research effort.Another possible reason for decline in this species has been tied to the Nutritional Stress Hypothesis. The lack of prey corresponds to the decrease in population. In females specifically, obtaining an insufficient amount of nutrients has resulted in the failure to complete their pregnancies to full term.In October 2013, the eastern Steller sea lion was taken off the U.S. Endangered Species List after a major population comeback over the past several years.Eared seal Marine Mammal Center – Steller Sea Lion US National Marine Fisheries Service Steller Sea Lion web.

Laser printing. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively-charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically-charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by.

Laser printing. reflecting light off an existing document onto the exposed drum.Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.## History.In the 1960s, the Xerox Corporation held a dominant position in the photocopier market. In 1969, Gary Starkweather, who worked in Xerox's product development department, had the idea of using a laser beam to "draw" an image of what was.

Laser printing. to be copied directly onto the copier drum. After transferring to the recently formed Palo Alto Research Center (Xerox PARC) in 1971, Starkweather adapted a Xerox 7000 copier to make SLOT (Scanned Laser Output Terminal). In 1972, Starkweather worked with Butler Lampson and Ronald Rider to add a control system and character generator, resulting in a printer called EARS (Ethernet, Alto Research character generator, Scanned laser output terminal)—which later became the Xerox 9700 laser printer. 1976: The first commercial implementation of a laser printer, the IBM 3800, was released. It was designed for data centers, where it replaced line printers.

Laser printing. Japanese camera and optics company Canon developed the Canon LBP-10, a low-cost desktop laser printer. Canon then began work on a much-improved print engine, the Canon CX, resulting in the LBP-CX printer. Having no experience in selling to computer users, Canon sought partnerships with three Silicon Valley companies: Diablo Data Systems (who rejected the offer), Hewlett-Packard (HP), and Apple Computer. 1981: The first small personal computer designed for office use, the Xerox Star 8010, reached market. The system used a desktop metaphor that was unsurpassed in commercial sales, until the Apple Macintosh. Although it was innovative, the Star workstation was.

Laser printing. a prohibitively-expensive () system, affordable only to a fraction of the businesses and institutions at which it was targeted. 1984: The first laser printer intended for mass-market sales, the HP LaserJet, was released; it used the Canon CX engine, controlled by HP software. The LaserJet was quickly followed by printers from Brother Industries, IBM, and others. First-generation machines had large photosensitive drums, of circumference greater than the loaded paper's length. Once faster-recovery coatings were developed, the drums could touch the paper multiple times in a pass, and therefore be smaller in diameter. 1985: Apple introduced the LaserWriter (also based on.

Laser printing. page is known as a raster line or scan line.Laser printing differs from other printing technologies in that each page is always rendered in a single continuous process without any pausing in the middle, while other technologies like inkjet can pause every few lines. To avoid a buffer underrun (where the laser reaches a point on the page before it has the dots to draw there), a laser printer typically needs enough raster memory to hold the bitmap image of an entire page.Memory requirements increase with the square of the dots per inch, so 600 dpi requires a minimum of.

Laser printing. or 8,388,608 bits, which is just large enough to hold the entire page at 300 dpi, leaving about 100 kilobytes to spare for use by the raster image processor.In a color printer, each of the four CMYK toner layers is stored as a separate bitmap, and all four layers are typically preprocessed before printing begins, so a minimum of 4 megabytes is needed for a full-color letter-size or A4-size page at 300 dpi.During the 1980s, memory chips were still very expensive, which is why entry-level laser printers in that era always came with four-digit suggested retail prices in US dollars.

Laser printing. Memory prices later decreased significantly, while rapid improvements in the performance of personal computers and peripheral cables enabled the development of low-end laser printers which offload rasterization to the sending PC. For such printers, the operating system's print spooler renders the raw bitmap of each page into the PC's system memory at the target resolution, then sends that bitmap directly to the laser (at the expense of slowing down all other programs on the sending PC). The appearance of so-called "dumb" or "host-based" laser printers from NEC made it possible for the retail cost of low-end 600-dpi laser printers to.

Laser printing. decrease to as low as US$700 by early 1994 and US$600 by early 1995.1200 dpi printers have been widely available in the home market since 2008. 2400 dpi electrophotographic printing plate makers, essentially laser printers that print on plastic sheets, are also available.## Charging.In older printers, a corona wire positioned parallel to the drum or, in more recent printers, a primary charge roller, projects an electrostatic charge onto the photoreceptor (otherwise named the photoconductor unit), a revolving photosensitive drum or belt, which is capable of holding an electrostatic charge on its surface while it is in the dark.An AC bias.

Laser printing. silicon nitride.## Exposing.A laser printer uses a laser because lasers are able to form highly-focused, precise, and intense beams of light, especially over the short distances inside of a printer. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, writing pixels at rates up to sixty-five million times per second. The drum continues to rotate during the sweep, and the angle of sweep is canted very slightly to compensate for this motion. The stream of rasterized data held in the printer's memory rapidly turns.

Laser printing. the laser on and off as it sweeps.The laser beam neutralizes (or reverses) the charge on the surface of the drum, leaving a static electric negative image on the drum's surface which will repel the negatively-charged toner particles. The areas on the drum which were struck by the laser, however, momentarily have no charge, and the toner being pressed against the drum by the toner-coated developer roll in the next step moves from the roll's rubber surface to the charged portions of the surface of the drum.Some non-laser printers (LED printers) use an array of light-emitting diodes spanning the width.

Laser printing. uniformly heats the roller from the inside. For proper bonding of the toner, the fuser roller must be uniformly hot.Some printers use a very thin flexible metal foil roller, so there is less thermal mass to be heated and the fuser can more quickly reach operating temperature. If paper moves through the fuser more slowly, there is more roller contact time for the toner to melt, and the fuser can operate at a lower temperature. Smaller, inexpensive laser printers typically print slowly, due to this energy-saving design, compared to large high-speed printers where paper moves more rapidly through a high-temperature.

Laser printing. (on some very fast, expensive printers) a xenon flash lamp. The warmup process that a laser printer goes through when power is initially applied to the printer consists mainly of heating the fuser element.## Malfunctions.The mechanism inside a laser printer is somewhat delicate and, once damaged, often impossible to repair. The drum, in particular, is a critical component: it must not be left exposed to ambient light for more than a few hours, as light is what causes it to lose its charge and will eventually wear it out. Anything that interferes with the operation of the laser such as.

Laser printing. formulations may not match the original specifications in terms of either tendency to accept a negative charge, to move to the discharged areas of the photoreceptor drum from the developer roll, to fuse appropriately to the paper, or to come off the drum cleanly in each revolution.## Performance.As with most electronic devices, the cost of laser printers has decreased significantly over the years. In 1984, the HP LaserJet sold for $3500, had trouble with even small, low-resolution graphics, and weighed 32 (kg). By the late 1990s, monochrome laser printers had become inexpensive enough for home-office use, having displaced other printing.

Laser printing. technologies, although color inkjet printers (see below) still had advantages in photo quality reproduction. , low-end monochrome laser printers can sell for less than $75, and while these printers tend to lack onboard processing and rely on the host computer to generate a raster image, they nonetheless outperform the 1984 LaserJet in nearly all situations.Laser printer speed can vary widely, and depends on many factors, including the graphic intensity of the job being processed. The fastest models can print over 200 monochrome pages per minute (12,000 pages per hour). The fastest color laser printers can print over 100 pages per.

Laser printing. minute (6000 pages per hour). Very high-speed laser printers are used for mass mailings of personalized documents, such as credit card or utility bills, and are competing with lithography in some commercial applications.The cost of this technology depends on a combination of factors, including the cost of paper, toner, drum replacement, as well as the replacement of other items such as the fuser assembly and transfer assembly. Often printers with soft plastic drums can have a very high cost of ownership that does not become apparent until the drum requires replacement.Duplex printing (printing on both sides of the paper) can.

Laser printing. halve paper costs and reduce filing volumes, albeit at a slower page-printing speed because of the longer paper path. Formerly only available on high-end printers, duplexers are now common on mid-range office printers, though not all printers can accommodate a duplexing unit.In a commercial environment such as an office, it is becoming increasingly common for businesses to use external software that increases the performance and efficiency of laser printers in the workplace. The software can be used to set rules dictating how employees interact with printers, such as setting limits on how many pages can be printed per day, limiting.

Laser printing. usage of color ink, and flagging jobs that appear to be wasteful.## Color laser printers.Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.Color printing adds complexity to the printing process because very slight misalignments known as registration errors can occur between printing each color, causing unintended color fringing, blurring, or light/dark streaking along the edges of colored regions. To permit a high registration accuracy, some color laser printers use a.

Laser printing. Color laser transfer printers.Color laser transfer printers are designed to produce transfer media which are transfer sheets designed to be applied by means of a heat press. These transfers are typically used to make custom T-shirts or custom logo products with corporate or team logos on them.2-part Color laser transfers are part of a two-step process whereby the color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK); however, newer printers designed to print on dark T-shirts utilize a special white toner allowing them to make transfers for dark garments or dark business products.The CMYK.

Laser printing. color printing process allows for millions of colors to be faithfully represented by the unique imaging process.## Business-model comparison with inkjet printers.Manufacturers use a similar business model for both low-cost color laser printers and inkjet printers: the printers are sold cheaply while replacement toners and inks are relatively expensive. A color laser printer's average running cost per page is usually slightly less, even though both the laser printer and laser toner cartridge have higher upfront prices, as laser toner cartridges print many more sheets relative to their cost than inkjet cartridges. Inkjet printers are better at printing photographs and color.

Laser printing. records, and keeping in mind that there are color laser printers, they're more costly.The print quality of color lasers is limited by their resolution (typically 600–1200 dpi) and their use of just four color toners. They often have trouble printing large areas of the same or subtle gradations of color. Inkjet printers designed for printing photos can produce much higher quality color images. An in-depth comparison of inkjet and laser printers suggest that laser printers are the ideal choice for a high quality, volume printer, while inkjet printers tend to focus on large-format printers and household units. Laser printers offer.

Laser printing. more precise edging and in-depth monochromatic color. In addition, color laser printers are much faster than inkjet printers, although being generally larger and bulkier.## Anti-counterfeiting marks.Many modern color laser printers mark printouts by a nearly invisible dot raster, for the purpose of traceability. The dots are yellow and about 0.1 (mm) in size, with a raster of about 1 (mm). This is purportedly the result of a deal between the US government and printer manufacturers to help track counterfeiters. The dots encode data such as printing date, time, and printer serial number in binary-coded decimal on every sheet of paper.

Laser printing. printer users, this technique also increases waste, and thus increases pressure on the environment. For these toner cartridges (as with inkjet cartridges), reset devices can be used to override the limitation set by the smart chip. Also, for some printers, online walk-throughs have been posted to demonstrate how to use up all the ink in the cartridge. These chips offer no benefit to the end-user—some laser printers used an optical mechanism to assess the amount of remaining toner in the cartridge rather than using a chip to electrically count the number of printed pages, and the chip's only function was.

Laser printing. toner spills into the laser printer, a special type of vacuum cleaner with an electrically conductive hose and a high-efficiency (HEPA) filter may be needed for effective cleaning. These specialized tools are called "ESD-safe" (Electrostatic Discharge-safe) or "toner vacuums".## Ozone hazards.As a normal part of the printing process, the high voltages inside the printer can produce a corona discharge that generates a small amount of ionized oxygen and nitrogen, which react to form ozone and nitrogen oxides. In larger commercial printers and copiers, an activated carbon filter in the air exhaust stream breaks down these noxious gases to prevent pollution.

Laser printing. of the office environment.However, some ozone escapes the filtering process in commercial printers, and ozone filters are not used at all in most smaller home printers. When a laser printer or copier is operated for a long period of time in a small, poorly-ventilated space, these gases can build up to levels at which the odor of ozone or irritation may be noticed. A potential health hazard is theoretically possible in extreme cases.## Respiratory health risks.According to a 2012 study conducted in Queensland, Australia, some printers emit sub-micrometer particles which some suspect may be associated with respiratory diseases. Of 63.

Laser printing. printer emissions with adverse health outcomes were located" and that several assessments conclude that "risk of direct toxicity and health effects from exposure to laser printer emissions is negligible". The review also observes that, because the emissions have been shown to be volatile or semi-volatile organic compounds, "it would be logical to expect possible health effects to be more related to the chemical nature of the aerosol rather than the physical character of the ‘particulate’ since such emissions are unlikely to be or remain as ‘particulates’ after they come into contact with respiratory tissue".The German Social Accident Insurance has commissioned.

Laser printing. a human study project to examine the effects on health resulting from exposure to toner dusts and from photocopying and printing cycles. Volunteers (23 control persons, 15 exposed persons and 14 asthmatics) were exposed to laser printer emissions under defined conditions in an exposure chamber. The findings from the study based on a broad spectrum of processes and subjects fail to confirm that exposure to high laser printer emissions initiates a verifiable pathological process resulting in the reported illnesses.A much-discussed proposal for reducing emissions from laser printers is to retrofit them with filters. These are fixed with adhesive tape to.

Laser printing. the printer's fan vents to reduce particle emissions. However, all printers have a paper output tray, which is an outlet for particle emissions. Paper output trays cannot be provided with filters, so it is impossible to reduce their contribution to overall emissions with retrofit filters.## Air-transport ban.After the 2010 cargo plane bomb plot, in which shipments of laser printers with explosive-filled toner cartridges were discovered on separate cargo airplanes, the US Transportation Security Administration prohibited pass-through passengers from carrying toner or ink cartridges weighing over 1 (lb) on inbound flights, in both carry-on and checked luggage. "PC Magazine" noted that.

Cane toad. The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus "Rhinella", which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus "Bufo".The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene in Colombia is indistinguishable.

Cane toad. from modern cane toads from northern South America. It was discovered in a floodplain deposit, which suggests the "R. marina" habitat preferences have long been for open areas. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Adults average 10 – 15 (cm) in length; the largest recorded specimen had a snout-vent length of 24 (cm).The cane toad has poison glands, and the tadpoles are highly toxic to most animals if ingested.

Cane toad. "Dominican toad", "giant marine toad", and "South American cane toad". In Trinidadian English, they are commonly called "crapaud", the French word for toad.The genus "Rhinella" is considered to constitute a distinct genus of its own, thus changing the scientific name of the cane toad. In this case, the specific name "marinus" (masculine) changes to "marina" (feminine) to conform with the rules of gender agreement as set out by the International Code of Zoological Nomenclature, changing the binomial name from "Bufo marinus" to "Rhinella marina"; the binomial "Rhinella marinus" was subsequently introduced as a synonym through misspelling by Pramuk, Robertson, Sites,.

Cane toad. and Noonan (2008). Though controversial (with many traditional herpetologists still using "Bufo marinus") the binomial "Rhinella marina" is gaining in acceptance with such bodies as the IUCN, Encyclopaedia of Life, Amphibian Species of the World and increasing numbers of scientific publications adopting its usage.Since 2016, cane toad populations native to Mesoamerica and northwestern South America are sometimes considered to be a separate species, "Rhinella horribilis".In Australia, the adults may be confused with large native frogs from the genera "Limnodynastes", "Cyclorana", and "Mixophyes". These species can be distinguished from the cane toad by the absence of large parotoid glands behind their.

Cane toad. toads lose the toxicity that protected them as eggs and tadpoles, but have yet to fully develop the parotoid glands that produce bufotoxin. Only an estimated 0.5% of cane toads reach adulthood, in part because they lack this key defense - but also due to tadpole cannibalism. Although cannibalism does occur in the native population in South America, the rapid evolution occurring in the unnaturally large population in Australia has produced tadpoles 30x more likely to be "interested" in cannibalising their siblings, and 2.6x more likely to actually "do so". They have also evolved to shorten their tadpole phase in.

Cane toad. Saw-shelled Turtles have also been seen successfully and safely eating cane toads.## Distribution.The cane toad is native to the Americas, and its range stretches from the Rio Grande Valley in South Texas to the central Amazon and southeastern Peru, and some of the continental islands near Venezuela (such as Trinidad and Tobago). This area encompasses both tropical and semiarid environments. The density of the cane toad is significantly lower within its native distribution than in places where it has been introduced. In South America, the density was recorded to be 20 adults per 100 m (109 yd) of shoreline, 1.

Cane toad. in spite of the failure of the earlier introductions. On September 8, 2013, the cane toad was also discovered on the island of New Providence in the Bahamas.## The Philippines.The cane toad was first introduced deliberately into the Philippines in 1930 as a biological control agent of pests in sugarcane plantations, after the success of the experimental introductions into Puerto Rico. It subsequently became the most ubiquitous amphibian in the islands. It still retains the common name of "bakî" or "kamprag" in the Visayan languages, a corruption of 'American frog', referring to its origins. It is also commonly known as.

Cane toad. 17 months. The toads were sent to the other islands, and more than 100,000 toads were distributed by July 1934; eventually over 600,000 were transported.## Uses.Other than the use as a biological control for pests, the cane toad has been employed in a number of commercial and noncommercial applications. Traditionally, within the toad's natural range in South America, the Embera-Wounaan would "milk" the toads for their toxin, which was then employed as an arrow poison. The toxins may have been used as an entheogen by the Olmec people. The toad has been hunted as a food source in parts of.

Rhizophora mangle. Rhizophora mangle, the red mangrove, is distributed in estuarine ecosystems throughout the tropics. Its viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows."Rhizophora mangle" grows on aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree "(Schinus terebinthifolius)". The red mangrove itself is considered an invasive.

Rhizophora mangle. species in some locations, such as Hawaii, where it forms dense, monospecific thickets. "R. mangle" thickets, however, provide nesting and hunting habitat for a diverse array of organisms, including fish, birds, and crocodiles.## Distribution and habitat.Red mangroves are found in subtropical and tropical areas in both hemispheres, extending to near 28°N to S latitude. They thrive on coastlines in brackish water and in swampy salt marshes. Because they are well adapted to salt water, they thrive where many other plants fail and create their own ecosystems, the mangals. Red mangroves are often found near white mangroves ("Laguncularia racemosa"), black mangroves.

Rhizophora mangle. ("Avicennia germinans"), and buttonwood ("Conocarpus erectus") though often more seaward than the other species. Through stabilization of their surroundings, mangroves create a community for other plants and animals (such as mangrove crabs). Though rooted in soil, mangrove roots are often submerged in water for several hours or on a permanent basis. The roots are usually sunk in a sand or clay base, which allows for some protection from the waves.Specimens of "Moesziomyces aphidis" have been collected from water samples and on "Rhizophora mangle" leaves along the Perequê-Áçu River, in mangroves located in São Paulo State, Brazil.## Description.Red mangroves are easily.

Rhizophora mangle. distinguishable through their unique prop roots system and viviparous seeds. The prop roots of a red mangrove suspend it over the water, thereby giving it extra support and protection. They also help the tree to combat hypoxia by allowing it a direct intake of oxygen through its root structure.A mangrove can reach up to 80 (ft) in height in ideal conditions, but it is commonly found at a more modest 20 (ft). Its bark is thick and a grey-brown color. Mangrove leaves are 1 - 2 (in) wide and 3 - 5 (in) long, with smooth margins and an elliptical.

Rhizophora mangle. shape. They are a darker shade of green on the tops than on the bottoms. The tree produces yellow flowers in the spring.## Reproduction.As a viviparous plant, "R. mangle" creates a propagule that is in reality a living tree. Though resembling an elongated seed pod, the fully grown propagule on the mangrove is capable of rooting and producing a new tree. The trees are hermaphrodites, capable of self or wind pollination. The tree undergoes no dormant stage as a seed, but rather progresses to a live plant before leaving its parent tree. A mangrove propagule may float in brackish water.

Palau Nacional. The (Catalan for ‘National Palace’) is a building on the hill of Montjuïc in Barcelona. It was the main site of the 1929 International Exhibition. It was designed by Eugenio Cendoya and Enric Catà under the supervision of Pere Domènech i Roura. Since 1934 it has been home to the National Art Museum of Catalonia.With a ground surface of 32,000 m2, the Spanish Renaissance-inspired building has a rectangular floor plan flanked by two side and one rear square sections, with an elliptical dome in the centre.

Eurasian teal. The Eurasian teal (Anas crecca), common teal, or Eurasian green-winged teal is a common and widespread duck which breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal.It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal ("A. carolinensis") was formerly (and.

Eurasian teal. sometimes is still) considered a subspecies of "A. crecca".## Taxonomy.The Eurasian teal belongs to the "true" teals, a group of small "Anas" dabbling ducks closely related to the mallard ("A. platyrhynchos") and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled teal ("A. flavirostris"). A proposed subspecies, "A. c. nimia" of the Aleutian Islands, differs only in slightly larger size; it is probably not distinct.Whether the Eurasian and green-winged teals are to be treated as one or two species is still being reviewed.

Eurasian teal. by the AOU, while the IUCN and BirdLife International separate them nowadays. Despite the almost identical and highly apomorphic nuptial plumage of their males, which continues to puzzle scientists, they seem well distinct species, as indicated by a wealth of behavioural, morphological and molecular data.The Eurasian teal was first scientifically named by Carl Linnaeus in his 1758 edition of "Systema naturae". His Latin description reads: "[Anas] macula alarum viridi, linea alba supra infraque oculos" – "a duck with green speculum, a white line above and below the eyes" – and his primary reference was the bird's description in his earlier.

Eurasian teal. work "Fauna Svecica". In fact, the description he used in "Systema Naturae" was the name under which the bird went in the "Fauna Svecica", demonstrating the value of his new binomial nomenclature by compressing the long-winded names formerly used in biological classification into much simpler scientific names like "Anas crecca". Linnaeus also noted in his description that earlier authors had already written about the Eurasan teal at length: Conrad Gessner had described it in the "Historiae animalium" as the "anas parva" ("small duck") among his "querquedulae" ("teals"); Ulisse Aldrovandi had called it "phascade" or "querquedula minor" ("lesser teal"), and was.

Eurasian teal. duly referenced by Francis Willughby who named the species "querquedula secunda Aldrovandi" ("the second teal of Aldrovandi"). John Ray may be credited with formally introducing the name "common teal", while Eleazar Albin called it simply "the teal". As regards the type locality Linnaeus simply remarked that it inhabits freshwater ecosystems in Europe.The scientific name is from Latin "Anas", "duck" and "kricka", the Swedish name for this species. The specific name of Linnaeus is onomatopoetic, referring to the male's characteristic call which was already discussed by Linnaeus' sources. The scientific name of the Eurasian teal—unchanged since Linnaeus' time— therefore translates as.

Fontaines de la Concorde. The Fontaines de la Concorde are two monumental fountains located in the Place de la Concorde in the center of Paris. They were designed by Jacques Ignace Hittorff, and completed in 1840 during the reign of King Louis-Philippe. The south fountain commemorates the maritime commerce and industry of France, and the north fountain commemorates navigation and commerce on the rivers of France.## History.Before the French Revolution, during the period 1753–1772, when the square was called Place Louis XV, the architect Jacques-Ange Gabriel designed a plan for a monumental statue of Louis XV with two fountains, but because of a lack.

Merino. The Merino is a breed or group of breeds of domestic sheep, characterised by very fine soft wool. It was established in Spain near the end of the Middle Ages, and was for several centuries kept as a strict Spanish monopoly; exports of the breed were not allowed, and those who tried risked the death penalty. During the eighteenth century, flocks were sent to the courts of a number of European countries, including France (where they developed into the Rambouillet), Hungary, the Netherlands, Prussia, Saxony and Sweden. The Merino subsequently spread to many parts of the world, including South Africa,.

Merino. Australia, and New Zealand. Numerous recognised breeds, strains and variants have developed from the original type; these include, among others, the American Merino and Delaine Merino in the Americas, the Australian Merino, Booroola Merino and Peppin Merino in Oceania, the Gentile di Puglia, Merinolandschaf and Rambouillet in Europe.The Australian Poll Merino is a polled (hornless) variant. Rams of other Merino breeds have long, spiral horns which grow close to the head, while ewes are usually hornless.## History.## Etymology.The name "merino" was not documented in Spain until the early 15th century, and its origin is disputed.Two suggested origins for the Spanish.

Merino. magistrate implausible.It also may be from the name of an Imazighen tribe, the "Marini" (or in Spanish, "Benimerines"), who occupied parts of the southwest of the Iberian peninsula during the 12th and 13th centuries. This view gains some support from the derivation of many mediaeval Spanish pastoral terms from Arabic or Berber languages. However, an etymology based on a 12th-century origin for Merino sheep when the Marinids were in Spain is unacceptable; the origin of the breed occurred much later.## Origin.The three theories of the origins of the Merino breed in Spain are: the importation of north African flocks in.

Merino. of Córdoba, and there is no record of extensive transhumance before the caliphate's fall in the 1030s. The Marinids, when a nomadic Zenata Berber tribe, held extensive sheep flocks in what is now Morocco, and its leaders who formed the Marinid Sultanate militarily intervened in southern Spain, supporting the Emirate of Granada several times in the late 13th and early 14th centuries. Although they may possibly have brought new breeds of sheep into Spain, there is no definite evidence that the Marinids did bring extensive flocks to Spain. As the Marinids arrived as an intervening military force, they were hardly.

Merino. in a position to protect extensive flocks and practice selective breeding.The third theory, that the Merino breed was created in Spain over several centuries with a strong Spanish heritage, rather than simply being an existing north African strain that was imported in the 12th century, is supported both by recent genetic studies and the absence of definitely merino wool before the 15th century. The predominant native sheep breed in Spain from pre-Roman times was the churro, a homogeneous group closely related to European sheep types north of the Pyrenees and bred mainly for meat and milk, with coarse, coloured wool.

Merino. Churro wool had little value, except where its ewes had been crossed with a fine wool breed from southern Italy in Roman times. Genetic studies have shown that the Merino breed most probably developed by the crossing of churro ewes with a variety of rams of other breeds at different periods, including Italian rams in Roman times, north African rams in the mediaeval period, and English rams from fine-wool breeds in the 15th century.Although Spain exported wool to England, the Low Countries and Italy in the 13th and 14th centuries this was only used to make cheap cloths. The earliest.

Merino. evidence of fine Spanish wool exports were to Italy in the 1390s and Flanders in the 1420s, although in both cases fine English wool was preferred. Spain became noted for its fine wool (spinning count between 60s and 64s) in the late 15th century, and by the mid-16th century its merino wool was acknowledged to equal that of the finest English wools.The earliest documentary evidence for merino wools in Italy dates to the 1400s, and in the 1420s and 1430s, merino wools were being mixed with fine English wool in some towns in the Low Countries to produce high quality.

Merino. merino wools. Later in the 14th century, similar non-merino wools were exported from the northern Castilian ports of San Sebastián, Santander, and Bilbao to England and the Low Countries to make coarse, cheap cloth. The quality of Spanish wools exported increased markedly in the late 15th century, as did their price, promoted by the efforts of the monarchs Ferdinand and Isabella to improve quality.Spain built up a virtual monopoly in fine wool exports in the final decades of the 15th century and in the 16th century, creating a substantial source of income for Castile. In part, this was because most.

Merino. the flocks started their return north.The three Merino strains that founded the world's Merino flocks are the Royal Escurial flocks, the Negretti and the Paula. Among Merino bloodlines stemming from Vermont in the US, three historical studs were highly important: Infantado, Montarcos and Aguires. In recent times, Merino and breeds deriving from Merino stocks have spread worldwide. However, there has been a substantial decline in the numbers of several European Merino breeds, which are now considered to be endangered breeds and are no longer the subject of genetic improvement. In Spain, there are now two populations, the commercial Merino flocks,.

Merino. most common in the province of Extremadura and an "historical" Spanish Merino strain, developed and conserved in a breeding centre near Cordoba. The commercial Merino flocks show considerable genetic diversity, probably because of their cross-breeding with non-Spanish Merino-derived breeds since the 1960s, to create a strain more suitable for meat production. The historical Spanish strain, bred from animals selected from the main traditional Spanish genetic lines to ensure the conservation of a purebred lineage, exhibits signs of inbreeding.Before the 18th century, the export of Merinos from Spain was a crime punishable by death. In the 18th century, small exportation of.

Merino. Merinos from Spain and local sheep were used as the foundation of Merino flocks in other countries. In 1723, some were exported to Sweden, but the first major consignment of Escurials was sent by Charles III of Spain to his cousin, Prince Xavier the Elector of Saxony, in 1765. Further exportation of Escurials to Saxony occurred in 1774, to Hungary in 1775 and to Prussia in 1786. Later in 1786, Louis XVI of France received 366 sheep selected from 10 different cañadas; these founded the stud at the Royal Farm at Rambouillet. In addition to the fine wool breeds mentioned,.

Merino. two rams and four ewes in 1787 by way of Portugal, and in 1792 purchased 40 Negrettis for King George III to found the royal flock at Kew. In 1808, 2000 Paulas were imported.The King of Spain also gave some Escurials to the Dutch government in 1790; these thrived in the Dutch Cape Colony (South Africa). In 1788, John MacArthur, from the Clan Arthur (or MacArthur Clan) introduced Merinos to Australia from South Africa.From 1765, the Germans in Saxony crossed the Spanish Merino with the Saxon sheep to develop a dense, fine type of Merino (spinning count between 70s and.

Merino. 80s) adapted to its new environment. From 1778, the Saxon breeding center was operated in the Vorwerk Rennersdorf. It was administered from 1796 by Johann Gottfried Nake, who developed scientific crossing methods to further improve the Saxon Merino. By 1802, the region had four million Saxon Merino sheep, and was becoming the centre for stud Merino breeding, and German wool was considered to be the finest in the world.In 1802, Colonel David Humphreys, United States Ambassador to Spain, introduced the Vermont strain into North America with an importation of 21 rams and 70 ewes from Portugal and a further importation.

Merino. of 100 Infantado Merinos in 1808. The British embargo on wool and wool clothing exports to the U.S. before the 1812 British/U.S. war led to a "Merino Craze", with William Jarvis of the Diplomatic Corps importing at least 3,500sheep between 1809 and 1811 through Portugal.The Napoleonic wars (1793–1813) almost destroyed the Spanish Merino industry. The old "cabañas" or flocks were dispersed or slaughtered. From 1810 onwards, the Merino scene shifted to Germany, the United States and Australia. Saxony lifted the export ban on living Merinos after the Napoleonic wars. Highly decorated Saxon sheep breeder Nake from Rennersdorf had established a.

Steller sea lion. The Steller sea lion (Eumetopias jubatus), also known as the Steller's sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus "Eumetopias" and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers.

Steller sea lion. over an extensive portion of their northern range in Alaska.## Description.Adult animals are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around 23 (kg), and remain dark in coloration for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably. Adult females measure 2.3 - 2.9 (m) in length, on average being 2.5 (m), and weigh 240 - 350 (kg), with an average of 263 (kg). Males continue to grow until their secondary sexual traits.

Steller sea lion. appear in their fifth to eighth year. Males are slightly longer than the females, growing to about 2.82 – 3.25 (m) long and averaging 3 (m) in length. Males have much wider chests, necks, and general forebody structure. Males can weigh between 450 – 1120 (kg), weighing on average 544 (kg). Males are further distinguished from females by broader and higher foreheads, flatter snouts, and a thick mane of coarse hair around their large necks. It is fitting then that their Latin name translates roughly as "maned one with the broad forehead".## Range.The range of the Steller sea lion extends.

Steller sea lion. from the Kuril Islands in the Sea of Okhotsk in Russia to the Gulf of Alaska in the north, down to Año Nuevo Island off the coast of central California to the south. They formerly bred as far south as the Channel Islands, but have not been observed there since the 1980s. Based on genetic anаlyses and local migration patterns, the global Steller sea lion population has traditionally been divided into an eastern and western stock at 144°W longitude, roughly through the middle of the Gulf of Alaska. Recent evidence suggests the sea lions in Russia in the Sea of.

Okhotsk and the Kuril Islands comprise a third Asian stock, while the sea lions on the eastern seaboard of Kamchatka and the Commander Islands belong to the western stock.In the summer, Steller sea lions tend to shift their range somewhat southward. Therefore, though there are no reproductive rookeries in Japan, several consistent haul-out sites are found around Hokkaidō in the winter and spring. Vagrants have been spotted in the Yellow Sea and Bohai Gulf and along the coast of Korea and China. The oldest fossil known of the species was found near Kanazawa, Japan and dates to the late Early.

Steller sea lion. Pleistocene (0.8 Ma).## Ecology.## Habitat.Steller sea lions tend to live in the coastal waters of the subarctic because of the cooler temperate climate of the area. Like all otariids, Steller sea lions are amphibious and spend some time in water and some on land. Typically, Stellar sea lions spend their time in the water feeding but haul-out onto land to reproduce, raise their pups, molt, and rest. Steller sea lions usually congregate on isolated islands because they are the ideal terrestrial habitat. These isolated islands are preferred by Stellar sea lions because they can avoid predation from terrestrial predators, easily.

Steller sea lion. thermoregulate (by means of cooling winds), and access offshore prey more easily. Some haul-out sites, known as rookeries, are commonly used for reproduction while other haul-out sites are used for other purposes like molting. However, both biotic and abiotic factors can influence the amount of time that Steller sea lions spend on land. Haul-out sites and haul-out abundance of the Steller sea lion can be determined by prey availability, predator abundance, tide levels, weather, etc.## Foraging.Steller sea lions are skilled and opportunistic marine predators, feeding on a wide range of fish and cephalopod species. Important diet components include walleye pollock,.

Steller sea lion. Atka mackerel, halibut, herring, capelin, flatfish Pacific cod, rockfish, sculpins, salmon, sand lance, and cephalopods such as various squid and octopus. They seem to prefer schooling fish and forage primarily between intertidal zones and continental shelves. They usually aggregate in groups of up to twelve in areas of prey abundance. They are known to aggregate near fishing vessels, preying on bycatch discards. Most of the data on their foraging comes from data collected off the coast of Alaska; little is known of their foraging behavior elsewhere.The composition of the diet of Steller sea lions varies seasonally and geographically; as opportunistic.

Steller sea lion. predators, they concentrate on the locally most abundant prey species. In addition to their primary marine environment, they sometimes enter estuaries and feed on brackish-water fish such as sturgeon. Very occasionally, they have been known to prey on northern fur seals, harbor seals, and sea otter pups. Records suggest that the range of their prey species has broadened over time.## Predation.Steller sea lions are top-tier carnivores, but are susceptible to predation, primarily by killer whales. Shark species are also possible predators: sleepers and great whites may prey on juvenile sea lions.## Behavior and life history.## Reproduction.Reproductively mature male sea lions.

Steller sea lion. gather together mid-spring on traditional, well-defined reproductive rookeries, usually on beaches on isolated islands. The larger, older males establish and defend distinct territories on the rookery. A week or so later, adult females arrive, accompanied occasionally by sexually immature offspring, and form fluid aggregations throughout the rookery. Like all other otariids, Steller sea lions are polygynous. However, unlike some other species, they do not coerce individual females into harems, but control spatial territories among which females freely move. Steller sea lions have used aquatic, semiaquatic, and terrestrial territories. Males with semiaquatic territories have the most success in defending them. The.

Steller sea lion. boundaries are defined by natural features, such as rocks, faults, or ridges in rocks, and territories can remain stable for 60 days. Though Steller sea lion males are generally tolerant of pups, one male filmed on Medny Island in Russia was documented killing and eating several pups in a first-ever recorded incident of cannibalism. Though researchers are uncertain as to the motives or reasons behind said attacks, it is suggested that the bull involved may have an abnormal personality akin to being psychotic.Pregnant females give birth soon after arriving on a rookery, and copulation generally occurs one to two weeks.

Steller sea lion. after giving birth, but the fertilized egg does not become implanted in the uterus until the fall. A fertilized egg may remain in embryonic diapause for up to three months before implanting and beginning to divide. Twins are rare. After a week or so of nursing without leaving the rookery, females begin to take progressively longer and more frequent foraging trips leaving their pups behind until at some point in late summer, when both the mother and pup leave the rookery together. This maternal attendance pattern is common in otariids. As pups get older the amount of time spent by.

Steller sea lion. females foraging out at sea increases. This continues until pups obtain the ideal body weight and energy reserves to eat on their own. A study conducted by the University of California, Santa Cruz found that on average male pups consume more milk than females. This may be due to the sexual dimorphism common to otariids. Reproductive males fast throughout the reproductive season, often without entering the water once from mid-May until August, when the structure of the reproductive rookeries begins to fall apart and most animals leave for the open seas and disperse throughout their range.The age at weaning is.

Steller sea lion. highly variable; pups may remain with their mothers for as long as four years. Incidents of mothers feeding daughters that are simultaneously feeding their own newborn pups have been documented, which is an extremely rare occurrence among mammals. A study done at Año Nuevo in 1983 found that female attendance and time spent with their pup was shaped by increasing nutritional demands of the pup and the pups suckling efficiency. Females averaged 21 hours ashore and 36 hours at sea. As the pups aged, females began to spend more time at sea again. As the pups matured, specifically at the.

Steller sea lion. sixth week past birth, the mother's sea time declined by 30 percent. There was no relationship between the pups' activity or physical excursion and their suckling time, age, or sex. Their suckling time, and age, and sex are unrelated to their use of energy. Labeled water studies showed that the pups' milk intake had a direct relationship to their size. Pups that consumed more milk were heavier than those that didn't. These findings show that the amount of time females spend onshore with their pups is based on their pup's suckling efficiency and nutritional demands.In the past, the low pup.

Steller sea lion. production has been tied to an increase in nutritional stress found in females. This was believed to have contributed to the decline in Steller sea lions common to Alaska.## Locomotion.The largest of the eared seals, Steller sea lions are quick swimmers, about as fast as the smaller California sea lions. Glide velocity of individual Steller sea lions has been measured as 2.9–3.4 meters or 1.2–1.5 body lengths per second, which is close to the optimal swim velocity of 1.4 body lengths per second based on the minimum cost of transport for California sea lions.A 2007 study of Steller sea lions.

Steller sea lion. found that a majority of thrust was produced during the drive phase of the fore flipper stroke cycle. Although previous findings on eared seals suggested that thrust was generated by the initial outward movement of the foreflippers or the terminal drag-based paddling phase, the 2007 study found that little or no thrust was generated during those phases. Swimming performance in sea lions is modulated by changes in the duration and intensity of movements without changing their sequence. Using criteria based on velocity and the minimum radius of turns, Steller's maneuverability is similar to other eared seals, superior to cetaceans, and.

Steller sea lion. inferior to many fish.## Diving.To be able to dive for a long period of time, Steller sea lions exhibit apnea, bradycardia, and peripheral vasoconstriction. This allows them to maximize their oxygen stores and efficiently forage during their dives. In addition to those adaptations, their thick blubber layer and outer fur layer keep their body insulated during dives.Trained Steller sea lions from Vancouver Aquarium were placed in the open ocean at the University of British Columbia's Open Water Research Station to study their diving metabolism and behavior. Steller sea lions' dives are more energetically costly if they perform dive bouts. The.

Steller sea lion. aerobic diving limit of Steller sea lions was observed to be affected by their nutritional state and feeding.## Communication.Like most otariids, Steller sea lions are vocal in air. Mature male sea lions have a range of vocalizations as part of their territorial behaviors, including belches, growls, snorts, and hisses that serve as warnings to others. Both males and females also produce underwater noises similar to their above water sounds, described as clicks, barks, and belches. The primary function of their vocalizations is for social behavior. Sonogram readings reported that Steller Sea Lions make discrete, low frequency pulses underwater that resemble.

Steller sea lion. the male "belching" territorial noise made in air. These underwater vocalizations have an average of 20–30 pulses per second.Vocalizations are critical to mother-pup pairs, as the mothers must find their pups in a crowded breeding area when they return from foraging. The mother and pup both use distinctive calls, like names, to help differentiate themselves among the crowd of other sea lions. Their aerial vocalizations have been described as similar to the bleats of sheep, and bellows.Because Steller sea lions are sexually dimorphic in size, their hearing differs in sensitivity, possibly due to differences in size of the hearing structures.

Steller sea lion. Females have a higher sensitivity than males, perhaps to hear the higher frequency calls of their pups. The Steller sea lion's hearing range also suggests that they are capable of hearing the underwater calls of one of their main predators, the killer whale.## Interactions with humans.Steller sea lion were hunted for meat and other commodities by prehistoric communities everywhere their range intersected with human communities. Aside from food and clothing, their skin was used to cover baidarkas and kayaks. A subsistence harvest on the order of 300 animals or less continues to this day in some native communities in Alaska.Historically,.

Steller sea lion. the sea lion has had only very slight commercial value. For example, in the 19th century their whiskers sold for a penny apiece for use as tobacco-pipe cleaners.Steller sea lions are sometimes killed intentionally by fishermen, as they are seen as competitors and a threat to fish stocks. Killing sea lions is strictly prohibited in the US and Russia, but in Japan a fixed number are still removed annually, ostensibly to protect their fisheries. In Canada, commercial hunting is prohibited, but limited hunting permits are occasionally granted if local culling is required—for example, nuisance animals destroying fish farms.In recent years,.

Steller sea lion. Steller sea lions have been known to enter the Columbia River estuary and feed on white sturgeon, several salmon species, and rainbow trout, some of which are also listed under the U.S. Endangered Species Act. They are found in the Columbia River nearly year round, with the exception of early summer, going as far upstream as Bonneville Dam. Though not as abundant as the California sea lion, they are still a concern for those agencies charged with managing the fish populations. Since the Steller sea lions are themselves protected under the Marine Mammal Protection Act, managers are compelled to use.

Steller sea lion. nonlethal deterrence methods, such as rubber bullets and noisemakers. Deterrence by the public is strictly forbidden.## Recent decline and subsequent recovery.While the populations of the eastern and Asian stocks appear stable, the population of the western stock, particularly along the Aleutian Islands, was estimated to have fallen by 70–80% since the 1970s. As a consequence, in 1997 the western stock of Steller sea lions was listed as endangered and the eastern stock was listed as threatened under the United States Endangered Species Act. They have since been the object of intense study and the focus of much political and scientific.

Steller sea lion. debate in Alaska.One suspected cause of their precipitous decline was the overfishing of Alaska pollock, herring, and other fish stocks in the Gulf of Alaska. This stems largely from the "junk-food hypothesis" representing a shift in their diet from fatty herring and capelin to leaner fare such as pollock and flounder, thereby limiting their ability to consume and store fat. Other hypotheses include increased predation by orcas and sharks, indirect effects of prey species composition shifts due to changes in climate, effects of disease or contaminants, shooting by fishermen, and others. The decline is certainly due to a complex of.

Steller sea lion. interrelated factors which have yet to be defined by the research effort.Another possible reason for decline in this species has been tied to the Nutritional Stress Hypothesis. The lack of prey corresponds to the decrease in population. In females specifically, obtaining an insufficient amount of nutrients has resulted in the failure to complete their pregnancies to full term.In October 2013, the eastern Steller sea lion was taken off the U.S. Endangered Species List after a major population comeback over the past several years.Eared seal Marine Mammal Center – Steller Sea Lion US National Marine Fisheries Service Steller Sea Lion web.

Waterbuck. 198 - 262 (kg) and females 161 - 214 (kg). Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55 - 99 (cm) long.Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits.

Waterbuck. in length. To some extent, the length of the horns is related to the bull's age. A rudimentary horn in the form of a bone lump may be found on the skulls of females.## Ecology and behaviour.Waterbuck are rather sedentary in nature, though some migration may occur with the onset of monsoon. A gregarious animal, the waterbuck may form herds consisting of six to 30 individuals. The various groups are the nursery herds, bachelor herds and territorial males. Herd size increases in summer, whereas groups fragment in the winter months, probably under the influence of food availability. As soon as.

Waterbuck. up to two months. At about three to four weeks, the calf begins following its mother, who signals it to do so by raising her tail. Though bereft of horns, mothers will fiercely defend their offspring from predators. Calves are weaned at eight months, following which time they join groups of calves of their own age. Young females remain with their mothers in nursery herds, or may also join bachelor herds. The waterbuck lives to 18 years in the wild and 30 years in captivity.## Distribution and habitat.The waterbuck is native to southern and eastern Africa (including countries such as.

Great frigatebird. The great frigatebird (Fregata minor) is a large seabird in the frigatebird family. There are major nesting populations in the tropical Pacific (including the Galapagos Islands) and Indian Oceans, as well as a tiny population in the South Atlantic.The great frigatebird is a large and lightly built seabird up to 105 cm long with predominantly black plumage. The species exhibits sexual dimorphism; the female is larger than the adult male and has a white throat and breast, and the male's scapular feathers have a purple-green sheen. In the breeding season, the male is able to distend his striking red gular.

Great frigatebird. the discrepancy between "minor", Latin for "smaller" in contrast with its common name. It is one of five closely related species of frigatebird that make up their own genus ("Fregata") and family (Fregatidae).

Common brushtail possum. The common brushtail possum (Trichosurus vulpecula, from the Greek for "furry tailed" and the Latin for "little fox", previously in the genus "Phalangista") is a nocturnal, semiarboreal marsupial of the family Phalangeridae, native to Australia and naturalised in New Zealand, and the second-largest of the possums.Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats. In most Australian habitats, eucalyptus leaves are a significant part of the diet, but rarely the sole item eaten. Its tail is prehensile and naked on its lower underside. The.

Common brushtail possum. four colour variations are silver-grey, brown, black, and gold.It is the Australian marsupial most often seen by city dwellers, as it is one of few that thrive in cities and a wide range of natural and human-modified environments. Around human habitations, common brushtails are inventive and determined foragers with a liking for fruit trees, vegetable gardens, and kitchen raids.The common brushtail possum was introduced to New Zealand in the 1850s to establish a fur industry, but in the mild subtropical climate of New Zealand, and with few to no natural predators, it thrived to the extent that it became a.

Common brushtail possum. and ecology.## Range and habitat.The common brushtail possum is perhaps the most widespread marsupial of Australia. It is found throughout the eastern and northern parts of the continent, as well as some western regions, Tasmania and a number of offshore islands, such as Kangaroo Island and Barrow Island. It is also widespread in New Zealand since its introduction in 1850. The common brushtail possum can be found in a variety of habitats, such as forests, semi-arid areas and even cultivated or urban areas. It is mostly a forest inhabiting species, however it is also found in treeless areas. In New.

Common brushtail possum. Zealand, possums favour broadleaf-podocarp near farmland pastures. In southern beech forests and pine plantations, possums are less common. Overall, brushtail possums are more densely populated in New Zealand than in their native Australia. This may be because Australia has more fragmented eucalypt forests and more predators. In Australia, brushtail possums are threatened by humans, tiger quolls, dogs, foxes, cats, goannas, carpet snakes, and powerful owls. In New Zealand, brushtail possums are threatened only by humans and cats. The IUCN highlight the population trend in Australia as decreasing.## Food and foraging.The common brushtail possum can adapt to numerous kinds of vegetation.

Common brushtail possum. New Zealand use many more den sites than those from Australia. Brushtail possums compete with each other and other animals for den spaces, and this contributes to their mortality. This is likely another reason why brushtail possum population densities are smaller in Australia than in New Zealand. Brushtail possums are usually not aggressive towards each other and usually just stare with erect ears. They vocalise with clicks, grunts, hisses, alarm chatters, guttural coughs, and screeching.## Reproduction and life history.The common brushtail possum can breed at any time of the year, but breeding tends to peak in spring, from September to.

Common brushtail possum. November, and in autumn, from March to May, in some areas. Mating is promiscuous and random; some males can sire several young in a season, while over half sire none. In one Queensland population, males apparently need a month of consorting with females before they can mate with them. Females have a gestation period of 16–18 days, after which they give birth to single young. A newborn brushtail possum is only 1.5 cm long and weighs only 2 g. As usual for marsupials, the newborn may climb, unaided, through the female's fur and into the pouch and attach to a.

Common brushtail possum. from which they may be forcibly ejected. In New Zealand's Ōrongorongo population, female young have been found to continue to associate with their mothers after weaning, and some inherit the prime den sites. A possible competition exists between mothers and daughters for dens, and daughters may be excluded from a den occupied by the mother. In forests with shortages of den sites, females apparently produce more sons, which do not compete directly for den sites, while in forests with plentiful den sites, female young are greater in number.## Relationship with humans.The common brushtail possum is considered a pest in some.

Common brushtail possum. areas, as it is known to cause damage to pine plantations, regenerative forest, flowers, fruit trees, and buildings. Like other possums, it is rather tolerant of humans and can sometimes be hand fed, although it is not encouraged, as their claws are quite sharp and can cause infection or disease to humans if scratched. It is a traditional food source for some indigenous Australians.## Australia.Its fur has been considered valuable and has been harvested. Although once hunted extensively for its fur in Australia, the common brushtail possum is now protected in mainland states, but it has only been partially protected.

Common brushtail possum. South Australia, they are fully protected and permits are required for trapping possums in human residences or for keeping or rescuing sick or injured wild possums and other native animals. In Queensland, they can only be trapped by licensed commercial relocators who must release possums within 25 metres of the point of capture to ensure that an animal is not released into another possum's home range (possums are less likely to survive if they are released into a new area where they do not have access to a den or must compete with a neighbouring possum for den space).## New.
