Another software, KERNEL, is available from the homepage. KERNEL is a program that accepts a file of x,y locational data and uses the kernel method to estimate home ranges. This module will eventually be incorporated into ANTELOPE when and if the authors get time to do so. Kernel methods have largely replaced harmonic mean estimates of home range in the last few years. They also have an advantage over Fourier methods in that they are not as sensitive to the size of the world in which the range is estimated.
