Population census and GPS tracking data for Mexican long-nosed bats (Leptonycteris nivalis) in Texas

The two files contain data associated with a final project report and
Master of Science thesis on foraging behavior and population trends of
endangered Mexican long nosed bats (Leptonycteris nivalis) funded by the
Texas Comptroller of Public Accounts Natural Resources Program. These cave
emergence data were collected from review of thermal infrared video of bat
emergence and summarize the colony size between 2008 to 2024 at Emory Cave
in Big Bend National Park, Texas. Separate census data are provided for
Mexican long-nosed bats and other species found in the cave in the
summer.  The location data (coordinates collected by Lotek
PinPoint GPS tags) for 21 bats was used to analyze foraging and movement
behavior and are provided in a second document. These data were collected
in summer of 2024 and have been adjusted by removing selected coordinates
within a buffered region near the roost of approximately 1 km.
