Our study focuses on the spatial ecology and seasonal habitat use of two aquatic turtles in order to understand the manner in which upland habitat use by humans shapes the aquatic activity, movement, and habitat selection of these species in an urban setting. We used radiotelemetry to follow 15 female Graptemys geographica (common map turtle) and each of ten male and female Trachemys scripta (red-eared slider) living in a man-made canal within a highly urbanized region of Indianapolis, IN, USA. During the active season (between May and September) of 2002, we located 33 of the 35 individuals a total of …

Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones
Antioch University Dissertations & Theses
This study examined whether female reproductive class (i.e., presence or absence of a calf) in humpback whales (Megaptera novaeangliae) affects female behavior and male-female interactions on the Hawaiian breeding grounds. From 2003-2008, 295 female-calf groups (with or without a male escort) and 256 female no-calf groups (with a male) were observed. Forty-one female no-calf groups were confirmed male-female pairs by genetic sexing or photo-identification. Focal follows of 36 male-female pairs and 50 female-calf groups (29 escorted and 21 unescorted female-calf groups) were analyzed for time budget and movement estimates. Relative fluke size (fluke photogrammetry, n=30) and sighting histories …
