U.S. Geological Surveys (USGS), Northern Rocky Mountain Science Center (NOROCK), is offering a funding opportunity to improve Bayesian model-based inferences for bat surveys. Field methods for monitoring bat populations in the western United States consist of stationary acoustic surveys, mobile transects, and summertime colony counts. The North American Bat monitoring program (NABat) relies on these core data streams to inform species status and trends assessments at range-wide extents, periodically (Loeb et al. 2015). NOROCKs research statistician was involved in conceptualizing the NABat program, developed the probabilistic master sample design underpinning the collaborative monitoring effort, continues to identify emerging statistical research and development needs for the Bats Stats Team, and provides sustained programmatic guidance and direction for the NABat program.
