We propose to evaluate reproductive vital rates of sagebrush songbirds in relation to key aspects of local climate. To accomplish this we will leverage several large existing datasets of nesting observations from over six thousand nests across multiple years and sites, archived weather station data (temperature, precipitation, and relative humidity), and gridded climate datasets (e.g., PRISM). To further examine whether particular landscapes and/or microhabitats may confer more protection in the face of increasingly more extreme weather events (e.g., high temperatures and drought) expected with climate change, we will incorporate habitat data collected remotely and at nests into climatic response models. Finally,...
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 1 (Kauffman et al. 2020) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data can be viewed at: https://westernmigrations.net. Data in this archive can be downloaded two ways. To download...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
