batch Leo the Lion from southerly and eastern Nevada are incite west to California , consort to a inherited study of nearly 740 big computed tomography .
The seven - yr field tracked mountain lion , asmountain lionsare also known , in both states to discover which field in the region serve as " sinks " ( home ground that animals move to at a greater rate than they pull up stakes ) and " source " ( areas that animals leave to dwell elsewhere ) .
A female mountain lion captured and collared in western Nevada for the field component of the study.
Because pot lions are hunted in Nevada , pull up stakes fewer cat and , therefore , more available land for migration , the researcher expected to find evidence of the animals traveling from California into Nevada . Instead , more lions moved west from cardinal Nevada to theSierra Nevada Mountainsin eastern California , the discipline encounter .
" It was diametrical than what we expected because lions are hunted in Nevada , and when territories are made vacant from hunting , then lions would move eastward because they are attracted to spread out territories , " said lead source Alyson Andreasen , a doctorial student in bionomics at the University of Nevada , Reno .
Overall , the not bad source of migrating animals was southerly Nevada , plate of the Desert National Wildlife Refuge and theNevada Test Site . Together , they render thou of air mile of land protected from hunting . Mostly , lions moved in a due north and south direction follow the orientation of the Great Basin ’s many peck range .
A female mountain lion captured and collared in western Nevada for the field component of the study.
" It ’s not a really high rate of give-and-take of individuals and genetics , but we do have evidence that someone are moving , " said Jon Beckmann , study carbon monoxide - author and a conservation ecologist with the Wildlife Conservation Society . " The next footstep is to dig a little deeper and define what that charge per unit really is and how many individuals there are per year , " Beckmann told OurAmazingPlanet .
The researchers tested DNA from 739 tissue samples cater by the Nevada Department of Wildlife and the California Department of Fish & Game . The animals were live - captured for enquiry , harvested by hunting watch ( in Nevada only ) , harvest for predation , or had died because of other lawsuit . The solution show only that mountain lions were journey across geographic part , not how often , or how many someone , or when . The study ’s goal was check themovement of mountain lionson a landscape painting scale , which is hard to do by collaring , Andreasen said .
The researchers are now trail individual animals with radio collars to well see migration between different populations in Nevada and California .
It ’s significant for direction and conservationto know population structure and how those populations interact with each other , " Andreasen recount OurAmazingPlanet .
Nevada is house to about 3,000 mountain lion , while California has 4,000 to 6,000 cats prowl its mountains and shores .
The finding were detailed online in the August 2012 early variation of the journal Molecular Ecology .
