We seek to understand how populations respond to natural and anthropogenic perturbations such as habitat destruction and degradation, disease outbreaks, and novel sources of mortality (e.g. wind turbines). We use a variety of quantitative approaches, including mark-recapture modeling techniques to estimate vital rates of bat species. Demography and population dynamics of bats are relatively poorly understood due to the logistical challenges of studying nocturnal, volant, cryptic and often wide-ranging animals.
