| population structure of spotted salamanders (ambystoma maculatum) in a fragmented landscape. | understanding the impacts of landscape-level processes on the population biology of amphibians is critical, especially for species inhabiting anthropogenically modified landscapes. many pond-breeding amphibians are presumed to exist as metapopulations, but few studies demonstrate the extent and consequences of this metapopulation structure. gene flow measures may facilitate the construction of more realistic models of population structure than direct measures of migration. this is especially tru ... | 2009 | 19192178 |
