Research Interests

Our initial objective was to investigate the possibility of accurately identifying free flying bats using Anabat II bat detectors.  Since 1995 my students and I have made extensive use of the system. Our first priority was to familiarize ourselves with echolocation calls of the different species in our area. To achieve this we have been assembling a library of call sequences from bats of known identity. This library has been built from mainly from recordings of bats that were initially captured in mist nets or harp traps and visually identified to species. After identification the bats were light tagged and released in likely foraging areas. Our  library contains calls recorded from these free flying bats, and from bats foraging at dusk or leaving a single species roost. By analyzing these known identity calls with the program Analook, we have been able to quantitatively identify bats by their echolocation call structure. We are now using this ability to study different aspects of bat behavior and ecology.

The winter of 2007-08 signaled the end of our research on the winter roosting and activity of Eastern red, silver-haired, and evening bats.  Included in this study was characterization of the responses of red bats to prescribed fires.  We are currently preparing a number of manuscripts for publication. 

During the summer of 2007 we began studies on the distribution and behavior of the endangered Indiana bat as they relate to the placement and operations of wind energy facilities in northern Missouri. This work continued and expanded during the summer of 2008, and I anticipate that this will continue as new sites are developed and operations begin on the facilities now under development.  These studies include capture and radio-telemetry as well as extensive Anabat II detector analyses that will examine activity patterns as they relate to habitat, weather, and seasonal variables.  GIS technology is being utilized as a means to describe and predict distribution and movements as they relate to these variables. 

We began a three year study of the distribution of Indiana bats in the Ozarks Scenic Riverways as part of a National Park Service project designed to manage the forests within the Park in a way that will not negatively impact this endangered species.  This study will include capture, telemetry, ultrasonic detection (Anabat II), and mapping (GIS).

  • Shannon Romeling. “Estimating and Evaluating the Effects of Mortality on Indiana Bat (Myotis sodalis) Populations at Proposed Wind Energy Facilities” 2009 – May 2012.

    This project will describe and evaluate two methods. The first method will estimate expected levels of Indiana bat (Myotis sodalis) mortality at proposed wind energy facilities and the second will estimate the potential effects of this mortality on the Indiana bat population over time.
