Observations (reduced to detected/not detected) of 45 vertebrate species (seven mammals, seven amphibians, and 31 reptiles) across Southern California pitfall sampling projects conducted between 1995 through 2015. Habitat patch locations of every pitfall sampling project presented in a shapefile. Habitat patches were measured based on the size when pitfall sampling began within each. Sampling projects within the same geographic area may have different sized patches based on date of project sampling and if patch erosion occurred. A matrix of whether each species was expected within each habitat patch's species pool based on range maps and published records is also included. These data support the following publication:...

The Yellowknife Study Area (YSA), Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-sq km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made...
Synthetic bat call parameters recorded in an anecolic chamber using full spectrum receivers. Data were then converted to zero-crossing format to measure parameters such as minimum, average and maximum frequency, number of echoes and number of correctly identified files
