Mechanisms driving variation in American marten winter rest site use across the Western Great Lakes RegionNARA Subscribed
At high latitudes, the thermal protection of snowpack is important for many small-bodied mammal species during the winter. As depth and persistence of snow changes due to climate change, species that rely on snowpack’s insulation must increasingly depend on alternative thermal refuges. For the American marten ( Martes americana ), winter rest sites are predominantly in ground microsites. In some regions, however, martens prima...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Climate change decreases the cooling effect from postfire albedo in boreal North AmericaNARA Subscribed
Fire is a primary disturbance in boreal forests and generates both positive and negative climate forcings. The influence of fire on surface albedo is a predominantly negative forcing in boreal forests, and one of the strongest overall, due to increased snow exposure in the winter and spring months. Albedo forcings are spatially and temporally heterogeneous and depend on a variety of factors related to soils, topography, climat...
Arbuscular mycorrhizal fungi ( AMF ) are ubiquitous soil fungi, forming mutualistic symbiosis with a majority of terrestrial plant species. They are abundant in nearly all soils, less diverse than soil prokaryotes and other intensively studied soil organisms and thus are promising candidates for universal indicators of land management legacies and soil quality degradation. However, insufficient data on how the composition of i...
