Variability In Movement Patterns And Habitat Use Of Two Species Of Pelecaniformes, Caroline Poli
Variability In Movement Patterns And Habitat Use Of Two Species Of Pelecaniformes, Caroline Poli
All Theses
Information regarding movement patterns of seabirds is useful for understanding prey abundance and distribution, predicting overlap between bird activity and anthropogenic stressors, and assessing the effectiveness of reserves at protecting nesting or foraging habitat(Cairns 1992, Weimerskirch 2007, Weimerskirch et al. 2010). I examined movement patterns of 40 brown pelicans (Pelecanus occidentalis) satellite tagged in December 2010 in South Carolina, USA, and tracked until July 2013. Birds exhibited individual variability in movement patterns and 25% of individuals remained near the breeding colony during nonbreeding. Birds captured in South Carolina that did migrate wintered as far south as Guatemala, prospected and used …

Finding The Needle And The Haystack: New Insights Into Locating Bog Turtles (Glyptemys Muhlenbergii) And Their Habitat In The Southeastern United States, Theresa Sonja Margareta Stratmann
All Theses
Because rare and cryptic species can be difficult to locate, distribution maps for these species are often inaccurate or incomplete. Bog Turtles (Glyptemys muhlenbergii) are emblematic of this challenge. In fact, conducting surveys of known, historical, and potential Bog Turtle habitat is a specific need stated in the Bog Turtle Northern Population Recovery Plan and in most Comprehensive Wildlife Conservation Strategies of states within the southern range. Therefore we examined ways to better locate Bog Turtle habitat and Bog Turtles within that habitat. First we determined a detection probability for a standardized trapping method so we could effectively survey for …
