Regional Differences In Wild North American River Otter (Lontra Canadensis) Behavior And Communication, Sarah Walkley
Dissertations
This study focuses on the vocalization repertoires of wild North American river otters (Lontra canadensis) in New York and California. Although they are the same species, these two established populations of river otters are separated by a significant distance and are distinct from one another. River otters are semi-aquatic social predators that can be found throughout North America. This is the first study to examine the vocalizations of wild river otters, and results are compared across field sites in the different regions. River otter vocalizations and behaviors in New York were recorded using Bushnell Aggressor trail cameras that …

On the other hand, observations of beluga whales in human care allow researchers to better understand many aspects of their daily lives and life histories that are difficult to assess in wild populations. Thus far, a catalog of socio-sexual behavior has been established based on observations of belugas; however, the developmental trajectory of socio-sexual behavior is not well-understood. The present study explored how socio-sexual …
