Wildlife dispersal ability and landscape connectivity in the northern Rocky Mountains

Science Spotlights Posted on: October 14, 2015
Increasing human populations have fueled urban development and land conversion, causing substantial loss and fragmentation of wildlife habitat. Researchers evaluated conditions for 108 different species across a large portion of the Northern Rockies in order to predict current and potential future patterns of fragmentation, prioritize keystone corridors for protection and enhancement, and identify which species in which places might require habitat restoration or assisted migration.

Spatiotemporal variation in resource selection: Insights from the American marten (Martes Americana)

Publications Posted on: September 30, 2014
Behavioral and genetic adaptations to spatiotemporal variation in habitat conditions allow species to maximize their biogeographic range and persist over time in dynamic environments. An understanding of these local adaptations can be used to guide management and conservation of populations over broad extents encompassing diverse habitats.

Effects of snow on fisher and marten distributions in Idaho

Publications Posted on: October 01, 2013
Studies have suggested that deep snow may limit fisher (Martes pennanti) distribution, and that fisher populations may in turn limit marten (Martes americana) distribution. We tested these hypotheses in the Northern Rocky Mountains of Idaho, a region which differs from previous study areas in its climate and relative fisher and marten abundance, but in which very little is known about their distributions.

Population connectivity and genetic diversity of American marten (Martes americana) in the United States northern Rocky Mountains in a climate change context

Publications Posted on: May 24, 2012
Climate change is likely to alter population connectivity, particularly for species associated with higher elevation environments. The goal of this study is to predict the potential effects of future climate change on population connectivity and genetic diversity of American marten populations across a 30.2 million hectare region of the in the US northern Rocky Mountains.

Simulating the effects of climate change on population connectivity of American marten (Martes americana) in the northern Rocky Mountains, USA

Publications Posted on: May 24, 2012
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.

Multi scale habitat relationships of Martes americana in northern Idaho, U.S.A.

Publications Posted on: April 03, 2012
We used bivariate scaling and logistic regression to investigate multiple-scale habitat selection by American marten (Martes americana). Bivariate scaling reveals dramatic differences in the apparent nature and strength of relationships between marten occupancy and a number of habitat variables across a range of spatial scales.

Limiting factors and landscape connectivity: the American marten in the Rocky Mountains

Publications Posted on: October 05, 2011
In mobile animals, movement behavior can maximize fitness by optimizing access to critical resources and minimizing risk of predation. We sought to evaluate several hypotheses regarding the effects of landscape structure on American marten foraging path selection in a landscape experiencing forest perforation by patchcut logging.

Appendix C: National Forest System status information

Publications Posted on: June 21, 2007
The information presented in this appendix was compiled from responses to two separate forest carnivore questionnaires distributed to Forest Service Regions 1, 2, 3, 4, 5, 6, and 10 in early 1993. Each region designated a primary contact to serve on the Habitat Conservation Assessment Management Team. It was the duty of each representative to provide and verify accuracy of data.

Appendix B: Fisher, lynx, wolverine summary of distribution information

Publications Posted on: June 21, 2007
We present maps depicting distributions of fisher, lynx, and wolverine in the western United States since 1961. Comparison of past and current distributions of species can shed light on population persistence, periods of population isolation, meta-population structure, and important connecting landscapes.

Appendix A: Ecoprovinces of the Central North American Cordillera and adjacent plains

Publications Posted on: June 21, 2007
The fundamental difference between the map presented here and other regional ecosystem classifications is that this map's ecological units are based on climatic processes rather than vegetation communities (map appears at the end of this appendix).
