Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack
Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack
Theses
Bubble stream production in belugas has been poorly characterized and its function is not well understood. I examined behavioral states when producing bubble streams (“bubbling”), and when bubbling calls, to determine whether bubbling was significantly associated with a particular call category or behavioral state. Using 19 hours of video and audio recordings collected over a two-day period, I quantified bubble streams of a 4-month old calf and an unrelated adult female housed together. Based on the overall activity budgets and pool of vocalizations for both animals, I calculated the expected counts of bubble streams with and without vocalizations, assuming that …

Masters Theses & Specialist Projects
Escalating human elephant conflict (HEC) continues to be a contributing factor
towards elephant decline, and crop raiding is the most common form of negative
human-elephant interactions. For communities that cannot reverse or prevent crop
raiding, it is necessary to contain HEC events through deterrent measures. Few
deterrent measures exist that combine practicality and affordability while also
preventing habituation by elephants. This project focused on comparing the efficacy of
deterrent methods to assess which was the most successful at preventing elephants
from entering crops in the farming community of Sasenyi, Kenya. In this paired-control
study, four deterrent methods were evaluated: acacia …
