摘要: The tri-colored bat (Perimyotis subflavus) is being reviewed for listing under the Endangered Species Act by United States Fish and Wildlife Service. It also listed as a species of greatest conservation need Texas Parks Department due to its susceptibility white-nose syndrome (WNS) in other states. Several colonies hibernating bats have been documented roosting culverts. Culverts are widespread part roadway infrastructure; thus, our objective was understand quantify which structural environmental factors best explain culvert use abundance Texas. We selected surveyed 207 culverts presence using Generalized Random Tessellation Stratified (GRTS) design opportunistic sampling across 10 12 level III ecoregions during winters 2016–2017 2017–2018. recorded features at each site. used zero-inflated Poisson regression identify explained bats. found that number sections predicted influenced length culvert, elevation, sections, portal height, obstruction, aspect, external VPD, temperature, NDVI. With current threats populations, there consider management roosts. In addition, it imperative further investigate potential WNS culvert-roosting more southern latitudes local regional planning efforts.
