This composite photograph, created from hundreds of sequential shots taken at one-second intervals, shows the emergence of 143 federally endangered Indiana bats (Myotis sodalis) from a single roost cluster. These bats face formidable threats, including habitat loss and white-nose syndrome. To help offset the loss of natural tree roosts, researchers and conservationists often install artificial roost structures, such as the rocket boxes shown here. The microclimate within these roosts is critical; optimal internal temperatures between 29–36°C help ensure successful pup development and overall colony health. My research project focuses on refining artificial roosts to maintain stable conditions amidst a changing climate. By tracking temperature profiles, adjusting design elements, and analyzing bat usage patterns, we aim to mitigate roost overheating and bolster the species’ resilience. This composite captures the scale of their nightly emergence and highlights the ongoing conservation efforts designed to safeguard their future.
