By attaching data loggers to bats, we found bats infected with white-nose syndrome awoke from hibernation more frequently, which may contribute to increased mortality.
Program to keep common species common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Links to projects, applications, status maps, and a searchable database.
Review of the size of breeding populations of Giant Canada geese by states in the Mississippi, Atlantic, Central, and Pacific flyways and the management problems caused by rapid increases of local breeding populations.
Proxy methods allow us to estimate ancient ocean temperatures but only if the method is calibrated using modern samples for which we measure the temperature. This is a proxy method using a sediment trap to collect planktonic foraminifera.
Deep-sea corals, also known as cold-water corals, have become a topic of interest due to conservation concerns over the impacts of trawling, exploration for oil and gas, and climate change.
The greatest threat to the future of the Koloa maoli as a unique species is cross-breeding with the introduced Mallard duck. This type of threat is termed genetic extinction.
