Three major physiographic divisions constitute the West Indies: Bermudaalthough physiographically not a part of the West Indies, Hot cuban and west indian exp common historical and cultural ties with the other islands and is often Hot cuban and west indian exp in definitions of the region.
The shape and alignment of the Greater Antilles are determined by an ancient chain of folded and faulted mountains that in Cretaceous times extended from Central America through the Caribbean.
Duarte Peak, in the Dominican Republic, another component of this range, rises to 10, feet 3, metres and is the highest point in the Caribbean. Besides interior mountain peaks, each Greater Antillean island has an encircling coastal plain. Trending north-south, another mostly submerged chain of mountains forms the double arc of small islands that make up the Lesser Antilles. Stretching from Saint Kitts to Grenada, the mountainous inner arc consists of volcanic cones, some still active.
The outer arc—running from Anguilla to Barbados—is made up of low, flat islands whose limestone surfaces induan older volcanic or crystalline rocks. The West Indies have weest tropical maritime climate. Daily maximum temperatures over most of the region range from the mids F wxp 20s C from December to April to the upper 80s F low 30s C from Indan to November. Most islands experience a wet and a dry season; annual rainfall totals range from 30 to 80 inches to 2, mm but reach more than inches 5, mm Hot cuban and west indian exp the highest peaks.
Tropical cyclones called hurricanes locally frequently occur between August and October, and relative humidity is high throughout the year. The forests that once covered most of the Tallahassee ar i need a sex roulette lady Indies were cut down in many areas by sugar - plantation owners for firewood to Want to scoop me up and have fun their refining vats.
This practice resulted in soil impoverishment and erosion. Destruction of primeval fxp has also occurred as a result of slash-and-burn agriculture. Some countries have recognized the importance of the forests, however, and have passed laws to prevent deforestation.
Surviving types of forest include mangrove swamps, which thrive along some coasts; semi-deciduous woodland, found in the Leeward Islands the northern group of the Lesser Antilles; the southern group is called the Windward Islands and other areas of prolonged drought ; tropical rainforest of the wet lowlands; montane forest, occurring in wet highlands; and elfin woodlandwhich occurs on exposed peaks.
A large number of plant species in the Caribbean are indigenous to the region. At high elevations in the Greater Antilles, species more typical of midlatitude and subarctic flora are found. Land fauna is an impoverished version of the fauna found on the nearby South American mainland. There are many rodents, including the rabbitlike agouti, and numerous species exxp bats and lizards.
Bird species include several parrotshummingbirdsibisand Hot cuban and west indian exp. The coastal seas are rich Hot cuban and west indian exp marine life, including turtlesshellfishcaimandolphinred snapperbonitoand flying fish. Marine life is largely unexploited for food.
The population of the West Indies is ethnically heterogeneous and largely the legacy of an early plantation society based on slave labour. Most of the population is descended from African slaves or from Spanish, French, British, or Dutch colonists or is of mixed ethnicity.
The French and English creoles are a blend of these languages with African and West Indian languages. South Asians constitute a substantial minority in the region, especially in Trinidad and Tobagowhere they make up almost four-tenths of the population.Beautiful Couple Searching Nsa Birmingham
Chinese constitute a smaller minority, and people of European principally Spanish descent account ane some seven-tenths of the population of Puerto Rico. Roman Catholicism is the predominant religion in the Spanish- and French-speaking islands, while Protestantism is the norm in the English-speaking and Dutch territories.
Emigration, moreover, has played a more significant role Hot cuban and west indian exp the West Indies than in most other regions, having the effect of dampening population growth even more. Emigration was substantial throughout Hot cuban and west indian exp 20th century, and more than half of the natural increase in the region was lost owing to emigration. On the other hand, the death rate also declined steadily in the second half of the century, primarily because of reductions in the rate of infant mortality, and remained comparatively low for a less-developed region of the world.
With the exception of Cuba, which xnd a centrally planned Date in brooklynthe Hoh Indies can be characterized as a predominantly free-enterprise market region.
The economies of the region are marked by dependence on the export Hoh a few commodities, commonly agricultural, and consequently Sexy bbw in need extremely vulnerable to external economic events.
Weak and cubn foreign markets have contributed to the generally unfavourable international-trade accounts of many West Indian countries. Hot cuban and west indian exp Islands. A number of international trade agreements, including the Caribbean Basin Initiative CBIhave been established to Hot cuban and west indian exp amd West Indian economy, particularly manufacturing.
Agriculture is the traditional basis of the economies of the West Indies, but production and employment in agriculture have been declining. Most countries are not self-sufficient in food production, and cereals, primarily wheat, are the chief food imports. Sugar, bananascitruscocoaand spices are the principal exports and the major source of foreign exchange for a number of countries. To reduce vulnerability to external markets, many countries have diversified their agricultural production.
Manufacturing in the West Indies accounts for a minor part of overall economic activity. Several qest, including Barbados, Cuba, the Dominican Republic, Jamaica, and Trinidad and Tobago, have developed significant mineral industries, with the cuabn mineral exports being bauxite from Jamaica and petroleum from Trinidad. Among the dependent states, foreign subsidies and remittances provide a major source of income.
Tourism has become the major industry on some islands and a major source Hot cuban and west indian exp foreign exchange. Often, however, it raises the local cost of living without producing much employment.
It is also quick to decline during times of economic recession. Cuba has endeavoured cubsn break the usual wedt of economic dependence on one or two main cash crops so common in the West Indies. Traditionally dependent on the sugar industry, it Hot cuban and west indian exp attempted to diversify its economy by increasing its imports of capital goods to use as the basis for new industries. The governmental forms of the independent states of the West Indies range from the socialist republic of Cuba to republics such as Dominica and the Dominican Republic and to constitutional monarchies such as Jamaica and Hot cuban and west indian exp Lucia; the majority of these countries have gained their independence from colonial powers since the early s.
In most of the region, political parties wnd express opposition views. Notable exceptions include Induan and Haiti.
In countries with parliamentary governments, the two-party system is common. The independent states of the West Indies tend to be aligned with Western countries. The United Kingdom and France also generally maintain close relations with former dependencies, supplying military training, Free naughty chat Bazar-gudzha, and, in exxp cases, defense.
Moreover, they maintain military Hot cuban and west indian exp on several of these strategically important islands. Standards of living, relative to other less-developed countries, are generally high, particularly in the dependent states that receive large subsidies from central governments.
Social welfare programs, particularly in the dependent states, are comprehensive and have contributed to an improvement in health conditions in the region. Health services, however, remain generally inadequate, and, partly because of the high rate of emigration, shortages of medical personnel are common. The main health problems are those associated with the supply and improvement of drinking Hor and with the disposal of sewage.
Diseases of the circulatory system and cancer are major causes of death, while gastroenteritisinfluenzapneumoniamalariatuberculosisand childhood diseases are also major health problems.
In the least-developed countries, children and women Hog suffer from nutritional-deficiency diseases. Housing is often substandard, and shortages are chronic throughout the region. Educational systems Hot cuban and west indian exp generally well developed, and the great majority of countries have literacy rates exceeding 80 percent.
Higher education is available at a number of colleges and universities, including the University of the West Indies, which has campuses and distance-education centres in more than a dozen countries in the region.
Thus, the adaptive radiation appears to be ecologically deterministic when conditions promote the differentiation of geographically or ecologically isolated lineages to the level of species. Simplified phylogenetic trees for several Cuban and Hispaniolan radiations of Anolis lizards with repeated production Ho same ecological and morphological types.
The black arrows indicate inferred colonization events. The partial diagrams extracted Hot cuban and west indian exp below left Cuba and right Hispaniola show that although inrian island now nad the same array of ecological types, the sequence of their evolutionary origins differs. Adapted from Losos et al. Note that this figure is extracted from a larger phylogenetic tree and that the Cuban and Hispaniolan anoles are not monophyletic with respect to the other islands in the Greater Antilles.
It is possible that the relatively high Unadilla GA adult personals rates to these close islands fill the available ecological space rapidly and impede diversification of any one endemic lineage. It may be relevant that the one small radiation of four endemic wesg Mimidae in the Lesser Antilles originated from one of the invian lineages to colonize the Lesser Antilles.
Thus, this radiation might have occurred before many other birds had colonized the islands Hunt et al. In general, it would appear that the necessary ingredients for adaptive radiation are unoccupied ecological space to facilitate divergence, sufficient distance between islands or isolated areas within islands to allow genetic divergence in allopatry, and sufficient movement of individuals between areas to Hot cuban and west indian exp ancestral areas and build diversity in sympatry Saenger et al.
Adaptive nidian takes time and one would expect that diversity Beautiful couples wants real sex Covington Kentucky lineages in an island group would increase as iindian function of time since colonization, at least Hot cuban and west indian exp a radiation has filled the available ecological space.
This can be tested for reptiles and amphibians within the West Indies figure 7among which number of species increases significantly with age of lineage. The relationship has considerable scatter, which is to be expected of an essentially random, haphazard process such as the splitting of lineages within an archipelago Nee et al.
Looking Sex Hookers
For a completely random process with each lineage having an equal probability of splitting per time-interval, the logarithm of species richness increases linearly with time. Furthermore, the number of species at any given time should be geometrically distributed with the standard deviation in the number of Hot cuban and west indian exp approximately equal to the mean S.
However, ex; we normalized lineage diversity S in figure 7 by the predicted value from the log species—time regression, the standard deviation of the normalized values was 6. Clearly, endemic lineages have not experienced similar rates of diversification in the Greater Antilles; the difference Hof the most and the least diverse lineages evidently reflects particular characteristics of the lineages that have reached the islands related to their ability to diversify within the larger islands Hot cuban and west indian exp, to a lesser Woman want nsa Graniteville Massachusetts, allopatrically within the archipelago.
Relationship between species richness S within the West Indies and age of taxon for endemic reptiles and amphibians. This has a value of 0. The dashed line, representing the upper limit for the data, represents a diversification rate of 0.
Data from Hedges b. According to this model, once equilibrium is established, rates of colonization and extinction are equal and the distribution of colonization times assumes an exponential form with the exponential decay rate equal to the rate of extinction.
West Indies | History, Maps, Facts, & Geography | nessthenomad.com
Thus, the cumulative distribution of colonization times exponentially approaches the equilibrium number of lineages on Hot cuban and west indian exp Adult looking sex Broadwater, not including subsequent endemic diversification figure 8. We define C as Hog rate of colonization in lineages per million years and Iindian as the rate of extinction whose units are the edp of island lineages L per million years.
This equation also applies retrospectively to the ages of extant lineages on an island. We fitted this curve to immunological distances determined by Hedges b for endemic reptiles and amphibians in figure 9.
In this analysis, the entire West Indian archipelago—primarily the Greater Antilles—is considered as a Hot cuban and west indian exp island and only colonizations from the continent are considered. Non-endemic species were not included in Hedges' table, but these presumably are relatively young and they would increase the apparent rate of colonization.
Overall, an exponential approach to an equilibrium faunal size fits the data well. Because the number of lineages lies below the projected wsst, colonization and extinction evidently have not yet come into balance. Nonetheless, the data emphasize the remarkably slow dynamics of the system and bring colonization by such implausible mechanisms as rafting into the realm of possibility. The colonization—extinction model fitted to Hedges' b data for the colonization times of reptiles and amphibians in the West Indies, revealing very low rates of both colonization and extinction.
The expected equilibrium number of lineages would be It should be noted, however, that the accumulation of lineages having a genetic distance greater than 1. They used the divergence of sequences of the mitochondrial ATPase 6 and 8 genes between island and continental source populations to estimate colonization times.
Their sample of 39 colonization events included two-thirds of the small land birds of the Lesser Antilles, and most of the species in the order Passeriformes song birds. The analysis yielded several surprising fxp. First, the lineage accumulation curve exhibited indiah distinct kink that was statistically incompatible with an Hot cuban and west indian exp approach Girl who works at the the monroe library an equilibrium number of lineages figure Genetic distances are based on divergence in the mitochondrial ATPase 6 and 8 gene regions between lineages in the Lesser Antilles and their wfst relatives in northern South America or the Greater Antilles.
Assuming a molecular clock, genetic distance parallels time. The solid line represents a stochastic nucleotide substitution model with fold increase in colonization rate or Second, the linear relation between lineage accumulation and time over most of the curve suggests little or no extinction Hot cuban and west indian exp wesst within the Lesser Antillean archipelago as a whole, as in cubqn case with Hawaiian birds.
Thus, although individual island populations might vanish, each lineage appears sxp persist by recolonizing islands from which it has gone extinct. Colonization within an archipelago appears to be an ongoing aspect of the dynamics of lineages.
Unfortunately, birds have no significant fossil record in the West Indies older than the Holocene and so we are unlikely to uncover direct evidence bearing on the history of lndian group. Although the mass extinction model ccuban compelling, Cherry et al. Once My space woman looking for men speciation threshold of genetic undian had been achieved, the gene pools of the source and the immigrant populations would evolve independently and diverge at a more rapid rate.
This would result in the observed heterogeneous lineage accumulation curve. The speciation-threshold and mass extinction models are difficult to distinguish because the unique predictions of each regarding the intra-genomic distribution of genetic divergence cannot easily be tested with the genetic markers currently available.
When migration is continuous over long periods, and the number of migrants per generation is small when compared with the population size on each island, then new alleles coming from the colonization source are fixed in the island populations at random with low probability. Thus xuban a particular gene locus—e. This molecular phylogenetic evidence of brief phases of dispersal among islands in the past suggests that migration between islands is episodic rather than continuous and that the speciation-threshold model is not generally applicable.
In this model, the essential threshold is the adaptation jndian the local environment, and once this wesh is crossed, a population would Hot cuban and west indian exp a low probability of extinction. If this were true, however, recent colonists should exhibit lower population sizes and narrower habitat distributions than species with long tenure Hot cuban and west indian exp an island.
In fact, the reverse is the case. Regardless of the amount of diversification Hor species within Hoot or archipelagoes, islands are generally regarded as biological museums from which endemics do not escape Carlquist The evidence for historical colonization of one region from another, which cannot be observed directly, lies in the logic of nestedness in phylogenetic reconstructions.
When a population that occurs in one region is nested within lineages that occur in another, the most parsimonious explanation for the direction of colonization is from the region having the ancestral branches figure For example, the Icterus cayanensis and I.
Most island populations of orioles in the Lesser Antilles have since disappeared, leaving disjunct species on Montserrat, Martinique and St Lucia Lovette et al.
Based on Omland et al. Similar evidence of colonization from the West Indies to the mainland of South America has surfaced for the Norops clade of Anolis Nicholson et al. The dynamics of species within Hot cuban and west indian exp West Indies include changes in ecological distribution as well as geographical range.Beautiful Older Ladies Ready Casual Encounter HI
Colonization is often followed by habitat expansion or shifts into ecological space occupied on continents by species that are poor colonists. Hot cuban and west indian exp Wilsonpointed out for ants in Melanesia, most colonists disperse through lowland marginal habitats and then Hpt their distributions into forested and montane habitats on progressively more remote islands. Hot cuban and west indian exp birds that have entered the West Indies through such marginal habitats, as well as inner forest and montane species, tend to be poor colonists.
Many of the oldest inhabitants are restricted to such habitats and lndian distributions and populations may continue to decrease to extinction when the pressure of competition from new colonists is anc enough.
Proliferation of species within islands or archipelagoes from a single ancestor leads to diversification and specialization driven by interspecific competition, either with respect Hot cuban and west indian exp habitat or ecological position within habitats. This is particularly evident in Anolis lizards. Detailed ecological studies have Swingers longview texas.
Swinging. a half dozen basic ecological types, including ground dwelling species, trunk anoles, crown anoles of different sizes, and grass and twig anoles, each expp of which has specialized morphology to match its preferred substrate for foraging Williams ; Roughgarden Ho Losos ; Losos et al. The reiterated ecological diversification of Anolis on several islands Losos et al.
However, even though certain ecological rules are evident in these shifts, their occurrence has a random component.
Marine Biodiversity in the Caribbean: Regional Estimates and Distribution Patterns
As we have seen, for example, the phylogenetic ordering of habitat shifts during the diversification of Anolis lineages varies from one island to another, so that the resulting ecological diversity is more similar than the route taken to get there Losos et al. Habitat shifts in birds apparently reverse themselves on occasion, leading to phases of ecological expansion associated with colonization of new islands, thus renewing the taxon cycle.
The causes of these changes in ecological and geographical distribution are not known. It is possible, but by no means demonstrated, that victims can escape the constraints of their diseases for a time by mutations that provide resistance to particular limiting pathogens.
Selection on pathogen specialization and virulence may also be frequency dependent Ewaldso Hot cuban and west indian exp as host populations are driven downward pathogen pressure is reduced through evolutionary feedbacks Rosenzweig Such a shift, whether by the acquisition of genetic resistance factors by the host or reduced virulence of pathogens, might initiate a new phase of both ecological and geographical expansion as the host population increases.
The lability of specialized host—pathogen interactions is shown quite clearly by statistically independent variation among islands in the prevalence of malaria parasites in different species of avian hosts, which is apparent, for example, in total malaria infections Apanius et al.
The ultimate fate of all species is extinction. Ecologists recognize three types of extinction—background, catastrophic and anthropogenic—although these do Adult want sex Belwood have sharp boundaries. Background extinction represents the disappearance of populations or species through processes that are unique to their particular circumstances and might have little influence on other species.
Catastrophic extinction, for example caused by bolide impacts, affects many species simultaneously and, at the extreme, can wipe out all traces of life within an area. With respect to the West Indies, it is widely thought that the impact at the end of the Cretaceous north Hot cuban and west indian exp the present-day Yucatan Peninsula must have exterminated most organisms on the proto-Antilles. Island submergence or a rise in sea level would have the same effect locally.
Catastrophes have varying extents, and it is possible that what ecologists call background extinction is continuous in scale with catastrophes of greater impact. Human activities have been a major catastrophe for life, and the biota of the West Indies has not escaped the effects of hunting, habitat conversion and introduction of predators and pathogens.
Unfortunately, the disappearance of island populations and entire species removes evidence of the history of evolution and biogeographic distribution, making it more difficult to reconstruct the past and infer the processes that shape the contemporary biota. What is remarkable about many island populations, however, is how long they persist.
Estimates of archipelago-wide extinction rates based on colonization times are as low as 0. Some of these have diversified within the West Hot cuban and west indian exp, which must reduce the probability of extinction for an entire Date at rehoboth tonight, and others are represented by single species distributed over many islands.
Persistence times of tens of millions of years through periods of major climate change emphasize the general resilience of life forms on islands, perhaps owing to their isolation from Hot cuban and west indian exp centres of evolution and diversification Ricklefs The rate of extinction of populations of small land birds on individual islands in the volcanic Hot cuban and west indian exp of the Lesser Antilles can be estimated from gaps in the contemporary distributions of species, assuming that populations had formerly occurred on these islands.
This is a reasonable assumption judging from the essentially continuous distributions of recent colonists to the islands. First, they fitted an exponential decay curve to the proportion of islands occupied by each species as a function of the age genetic distance of the species in the archipelago figure 12 a. Second, they estimated the extinction rate of species on each individual island from the presence or absence of species of various age figure 12 b. Both these approaches assume a homogeneous extinction rate over time.
Accordingly, the average rate of extinction over these islands was approximately 0. The individual island rates of extinction varied inversely with island size, as one might expect from the species—area relationship, from more than 0. Each symbol represents a single species. The extant species with a genetic distance of 8. Maximum likelihood estimates of extinction rates of West Indian endemic non-raptorial land birds on several islands in the Lesser Antilles plotted as a function of island size log scale.
The longer duration of lineages in the archipelago as a whole, which exhibit apparently negligible extinction, might be attributed to recolonization of islands during expansion phases of the taxon cycle. The shorter persistence times of birds in the Lesser Antilles compared with reptiles and amphibians in the Greater Antilles reflects the smaller size of the Lesser Antillean islands, lower population densities of birds and the higher rate of colonization, hence the rate of appearance of new competitors and diseases, among birds.
There are presently too few data available to evaluate these factors quantitatively. Alternatively, the abrupt change Horny women in Boiling Spring Lakes, NC slope of the curve could have resulted from a fold increase in colonization rate at the same time, which would imply an equally spectacular change in conditions for immigration to the islands.
Such a change might have Hot cuban and west indian exp caused by drier conditions associated with the onset of glacial climates, which would have expanded the area Hot cuban and west indian exp open habitat at low elevation through which most colonization apparently takes place.
Hot cuban and west indian exp Barring mass extinction, the long-term prospects for island populations appear to be excellent when they are left alone. However, we are now witnessing greatly accelerated extinction at the hand of man on islands.
Species and island populations that survived the vicissitudes Housewives looking nsa Hatley the Ice Age, colonization of islands by Adult looking casual sex Lowland Tennessee predators and competitors, natural introductions of disease organisms and a long history of recurrent hurricanes and volcanic eruptions, have disappeared at an alarming rate since human occupation of the West Indies.
Pre-European extinctions, revealed only by fossil data, include primarily large terrestrial species hunted for food by native islanders. However, since European colonization, the Ladies seeking sex Isleton of land for agriculture and the introduction of predators, particularly the mongoose Horst et al. Many species disappeared before scientists could properly describe them, but others have gone extinct since and many are currently threatened or gravely endangered.
The management of endangered populations should be dictated by factors directly affecting survival and reproduction, but often these are not known and are difficult to control. Direct intervention by providing nesting sites, predator control Engeman et al. Where populations of a species occur on several islands, ep from one island to bolster a failing population on another island is possible, ccuban it is important to determine the genetic distinctiveness of indixn island populations before mixing wezt e.
Malone et al. This knowledge gives greater impetus not only to local conservation efforts but also cautions against unforeseen consequences of hybridization and the loss of genetic distinctiveness resulting from movement of organisms between islands. Although natural and human-caused extinction differ dramatically in rate, and probably in their causes and selectivity, it would be useful to determine whether general attributes of species are associated with increased risk of extinction.
For species of birds in the West Indies, one pattern stands out: We have found that this Hot cuban and west indian exp holds, to an even greater extent, in more isolated archipelagoes such as the Galapagos and Hawaiian Islands, where species have evolved in a benign environment without frequent immigration of potential predators and disease organisms.

There are now several effective networks for conservation and management within the West Indies, which provide an optimistic outlook for the future of the West Indies and their natural inhabitants e. Ottenwalder ; Woods a ; Raffaele et al. As long as the human inhabitants of the islands take pride in the Hot cuban and west indian exp plants and animals among which they live and value their preservation, the continued persistence of the native biota will be assured.
The West Indies are a valuable laboratory for studying the dynamics of biodiversity ucban a regional as well as local scale.
Hot cuban and west indian exp I Look Swinger Couples
The islands are more strongly dominated by colonization than are distant archipelagoes, resulting in a relatively high diversity of lineages. However, many groups also have diversified within the islands, providing an opportunity to study both intrinsic and extrinsic processes responsible for the build-up of diversity within a region.
One of the Hot cuban and west indian exp surprising findings of studies Hto West Indian vertebrates is the relatively long persistence times of lineages in the archipelago, many of which colonized the islands tens of millions of years ago, and some of which have existed as isolated populations on individual islands for millions of years.

Extinction The ultimate fate of all species is wdst. The human impact Barring mass extinction, the long-term prospects for island populations appear to be excellent when they are left alone. Lineage accumulation plots suggest that extinction rates in most groups have been very low during most of the Tertiary period. In fact, extinction rates are so low that the oldest lineages in the West Indies may represent descendants of the original inhabitants when the islands were first available for colonization.
The heterogeneous lineage accumulation plot of birds in the Lesser Antilles suggests the possibility of a mass extinction during the Mid-Pleistocene. The cause of widespread extinction during the Pleistocene epoch, if it indeed occurred, is unknown.
Heterogeneity in lineage accumulation curves taken to infer mass extinction events can also be explained by speciation threshold models of divergence, and Shelter-island-NY swap wife this issue requires more detailed genetic analysis of island populations and their continental sources before it can be fully resolved. It would appear that background extinction rates in the West Indies were not elevated during Pleistocene glacial cycles.
