Are Point Counts of Boreal Songbirds Reliable Proxies for More Intensive Abundance Estimators?
Download2006
Villard, M.-A., Schmiegelow, F.K.A., Hannon, S.J., Toms, J.D.
Point counts are often used to provide information on abundance of songbirds. If data from point counts are to be compared in space or time, however, any bias in the estimate should be consistent and linearly related to the true abundance. Several studies have suggested that this assumption may...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...

Collisions of motorized transport with wildlife impact a wide range of species and can cause injuries and economic losses to people. On roads, vehicle collisions with animals have been studied extensively, resulting in mitigation measures that reduce collisions by segregating animals and...

Accurate assessment of how animals distribute themselves across the landscape is an essential component of ecological research. Ecologists often conduct surveys to subsample a representative portion of an area of interest and extrapolate their findings to a larger region. Acoustic surveys are...
