We are exploring models that relate measures of bat activity to environmental conditions, such as weather, moon phase, and day of year.
We are conducting daily fatality searches for bat carcasses in order to relate fatality pattern to measures of bat activity, as well as to daily environmental conditions - such as weather, moon phase, and day of year.
We are developing the theoretical statistical framework that would allow inference from known search effort and detectability parameters regarding estimated fatality when there are no or few observed carcasses. In addition, we are developing software that resource managers as well as developers can use to design fatality monitoring protocols optimized for different objectives.
We are investigating ways to accurately estimate this fraction in order to improve the accuracy of estimates and the efficiency of searching.
We are creating an estimator that allows a more general parameterization of carcass arrival and persistence times, while accommodating the different assumptions regarding the likelihood that a carcass is observed.
We are developing publicly available open-source software that uses data provided by the user to estimate the probability that a searcher will miss a carcass and the probability that a carcass will be removed before a searcher has the opportunity to observe it. The estimates are combined with the observed casualties and an estimate of the fraction of the population of killed animals expected...
The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy...
Three federal wildlife refuge complexes on the upper Texas coast include portions of the Columbia Bottomlands and other forests that are important for migratory birds and possibly bats: Texas Mid-Coast, Trinity River, and Chenier Plain.
Knowing where migratory birds consistently stop to rest and forage is critical for conservation planning, particularly along the northern and western Gulf where there is increased interest in energy development.

Evidence of Absence Webinar
This video describes a statistical software package called "Evidence of Absence" that can be used to provide evidence of compliance with incidental take permits. It will be useful to wildlife managers and wind energy operators to estimate, with reasonable certainty, that a certain number of birds or bats have been killed at wind energy facilities, even when no carcasses are found.
South Florida Information Access (SOFIA) was established to provide coherent information access in support of research, decision-making, and resource management for the South Florida ecosystem restoration effort.
The interactive sea-level rise visualization tool results from a collaborative effort between NOAA's Coastal Services Center, USGS WARC, and USGS Mississippi Water Science Center. The tool illustrates the scale of potential flooding, but not the exact location, and does not account for erosion, subsidence, sediment accretion, or future construction.
