Jonathan Q. Richmond, Duncan T. Reid, Kyle G. Ashton, Kelly R. Zamudio
2009, Conservation Genetics (10) 1281-1297
Populations rarely show immediate genetic responses to habitat fragmentation, even in taxa that possess suites of traits known to increase their vulnerability to extinction. Thus conservation geneticists must consider the time scale over which contemporary evolutionary processes operate to accurately portray the effects of habitat isolation. Here, we examine the...
