Northern long-eared bat day roost ecology and novel bat sampling techniques in the mid-Atlantic
White-nose syndrome (WNS), caused by the introduced fungal pathogen, Pseudogymnoascus destructans, has caused precipitous declines in bat populations including the now endangered northern long-eared bat (Myotis septentrionalis; NLEB). Remnant populations of NLEB have been found outside their …

Comparison of Creel Survey Data to Traditional Sampling Techniques in Pit-Lake Fisheries of Muhlenberg County, Kentucky
… similar to those generated through on-site sampling in 2011. Fish were collected via a combination of gill netting, seining, hook-and-line fishing, and boat-mounted electro-fishing. In two of the pit-lakes, the sampling-generated length frequency data was not significantly different from the …
