Abstract

Bat habitat use in the Northeast has been well studied, however, research has been focused on interior locations, leaving coastal areas relatively understudied. Cape Cod National Seashore (CCNS) is a coastal plain peninsula where our understanding of bat habitat associations is limited to historical data. I acoustically sampled sites within CCNS during 2015 and 2016 to quantify local and landscape factors associated with habitat use and species assemblage. I examined interspecific effects of co-occurrence between two bat species to understand factors influencing habitat use in CCNS. I found that coastal bats use sites similar to interior populations despite differences in dominant vegetation types. Myotis septentrionalis were found in relatively high numbers and availability of suitable habitat or competition with other species were not limiting factors to recovery on CCNS. Continued acoustic monitoring on CCNS should extend beyond summer habitat use and coordinate mist netting to improve power to draw inferences.
