Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel
Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel
Masters Theses & Specialist Projects
Substrate-borne vibrations, or biotremors, are utilized by vertebrates found in unique environments because biotremors are an effective way to transmit signals through dense media. Previous studies have shown that veiled chameleons (Chamaeleo calyptratus) are able to produce biotremors via specialized neck muscles. I hypothesized that during courtship and/or breeding, the veiled chameleon, a tree-dwelling species, would communicate with biotremors through branches. Additionally, I hypothesized that female call characteristics would differ between reproductive condition (i.e., receptive and non-receptive), while male call characteristics would differ between behavioral contexts (i.e., territorial vs. courtship). Chameleons were paired (one male, one female) and placed on …

Coyotes (Canis latrans) are highly adaptable, medium-sized carnivores that now inhabit nearly every large city in the United States and Canada. To help understand how coyotes have adapted to living in urban environments, we compared two ecologically and evolutionarily important behavioral traits (i.e., bold-shy and exploration-avoidance behavior) in two contrasting environments (i.e., rural and urban). Boldness is an individual’s reaction to a risky situation and exploration is an individual’s willingness to explore novel situations. Our results from both tests indicate that urban coyotes are bolder and more exploratory than rural coyotes and that within both populations there are …

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Student Scholar Symposium Abstracts and Posters
One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …
Time Series Observations Of Species Composition And Behavioral Interactions Of Fish At An Ocean Observatory Off The Coast Of Georgia, Amy E. Paquette
Time Series Observations Of Species Composition And Behavioral Interactions Of Fish At An Ocean Observatory Off The Coast Of Georgia, Amy E. Paquette
Honors Scholar Theses
The use of ocean observatories is expanding with the potential for collecting serial data with high temporal resolution at multiple sites within an ecosystem. Integration of underwater video cameras in observatory systems allow observation of vagile species and are useful tools for observing variations in behavior over time. In order to assess the utility of using video records for time series behavioral data I analyzed video records from an observatory site in the South Atlantic Bight (SAB) off the Coast of Georgia collected during the month of November in 2000, 2002 and 2004. Data were used to quantify annual variation …
