Abstract
Bats are taxonomically and ecologically diverse species who provide many ecosystem services. They are also sensitive to many anthropogenic stressors (e.g., urbanization, water quality, changes in climate), so changes in bat populations have historically been early sentinels of disturbance, facilitating focused conservation efforts. Unfortunately, following the introduction of white-nose syndrome (WNS) in 2006 in New York, the nation has seen variable but drastic declines in bat populations. The relationship between bats and their habitats is not well understood because they are wide-ranging and require multiple critical habitat types, but research is needed in order to meet conservation targets. In fall 2022, we assessed the abundance and diversity of bat species between forested, rural, and urban habitat types in northern New York. Each site was surveyed once using an ultrasonic bat detector thirty minutes after sunset, the most active feeding time for bat species. We hypothesized that bat abundance would be highest in the urban setting, with infrastructure providing increased roosting opportunity. However, highest species abundance and richness were both found at the forested site, likely because it was surveyed the earliest in the season. It was also the route with the most suitable habitat based on prior research suggesting bats need water for feeding and forests for roosting. The forested and rural sites showed 28.6% similarity, the rural and urban sites showed no similarity, and the forested and urban sites had 50% similarity. Understanding the disproportionate value that forest habitats provide for bat populations, we suggest considering conservation efforts which prioritize these ecosystems and link them to important riparian corridors.
