Simulating the effects of climate change on population connectivity of American marten (Martes americana) in the northern Rocky Mountains, USA
Wasserman, T.N., S.A. Cushman, A.S. Shirk, E.L. Landguth, and J.S. Littell. 2011. Simulating the effects of climate change on population connectivity of American marten (Martes americana) in the northern Rocky Mountains, USA. Landscape Ecology 27(2): 211-225, doi: 10.1007/s10980-011-9653-8.
We utilize empirically derived estimates of landscape resistance to assess current landscape connectivity of American marten Martes americana in the northern Rocky Mountains, USA, and project how a warming climate may affect landscape resistance and population connectivity in the future. We evaluate the influences of five potential future temperature scenarios involving different degrees of warming. We use resistant kernel dispersal models to assess population connectivity based on full occupancy of suitable habitat in each of these hypothetical future resistance layers. We use the CDPOP model to simulate gene exchange among individual martens in each of these hypothetical future climates. We evaluate: (1) changes in the extent, connectivity and pattern of marten habitat, (2) changes in allelic richness and expected heterozygosity, and (3) changes in the range of significant positive genetic correlation within the northern Idaho marten population under each future scenario.
