Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), Kathryn C. Laslie

Masters Theses & Specialist Projects

While substrate-borne vibrations are utilized by different reptile species, true conspecific communication via biotremors has not yet been demonstrated in reptiles. This study follows a preliminary report that the veiled chameleon (Chamaeleo calyptratus) could produce biotremors in communicative contexts. I tested chameleon behavioral sensitivity to vibrations by placing them on a dowel attached to a shaker emitting vibrations of 25, 50, 150, 300, and 600 Hz and then measured their changes in velocity before and after the stimulus. I then paired chameleons in various social contexts [anthropogenic disturbance (human disruption of animal); dominance (malemale; female-female C. calyptratus); courtship (male-female C. …

An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen

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 …
