Dolphin Behavioral Responses To Uncrewed Aerial Systems As A Function Of Exposure, Height, And Type, Savannah Damiano
Dolphin Behavioral Responses To Uncrewed Aerial Systems As A Function Of Exposure, Height, And Type, Savannah Damiano
Electronic Theses and Dissertations
Uncrewed aerial systems (UAS) are becoming a standard tool in the study of cetaceans, however, a comparative assessment of animal responses to UAS has not been established to gauge the most effective systems for cetacean study. We utilized Dolphin Quest Bermuda’s eleven bottlenose dolphins as subjects for such an investigation taking place over five weeks in 2022 and five weeks in 2023. The dolphins were evaluated for investigative behavioral responses to six off-the-shelf UAS types and a custom fixed wing system. Each UAS was flown in decreasing height vertically above the main dolphin lagoon to evaluate dolphin behavioral responses in …
Effects Of Anthropogenic Light And Noise On Anuran Breeding Behavior, Ashley Kobisk
Effects Of Anthropogenic Light And Noise On Anuran Breeding Behavior, Ashley Kobisk
Electronic Theses and Dissertations
The natural environment can be negatively impacted by a variety of human activities, including the production of artificial light at night and anthropogenic noise. Recent studies suggest that pollution from anthropogenic light and noise alters animal behavior. Despite being highly nocturnal and vocal animals, little attention has been given to anurans and the effects artificial light at night and anthropogenic noise have on their behavior. This study investigated the effects of artificial light at night and anthropogenic noise on anuran breeding systems in eastern Texas. Specifically, this study investigated whether (1) artificial light and anthropogenic noise altered calling behavior in …
Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow
Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow
Electronic Theses and Dissertations
Avian facial plumage, bill coloration, and feather microstructure may serve one or more adaptive functions. Several researchers have proposed that dark eyestripes, bills, and facial masks aid in reducing glare, however, there have been relatively few tests of this hypothesis. Dark facial markings have been shown to have an adaptive glare-reduction function in recent field studies of a few species, but this hypothesis has never been tested in a broad multispecies analysis. It is likely that feather microstructure influences feather brightness and has an effect on the efficacy of glare reduction properties of feathers. I examined the link between dark …

Personality In Stomatopod Crustaceans, Jillian Page Blenderman
Electronic Theses and Dissertations
Stomatopods, or mantis shrimp, are small, predatory crustaceans of tropical and subtropical waters. Mantis shrimp research has focused largely on their agonistic interactions and complex visual systems. Despite their broad behavioral repertoire, stomatopods have not yet been investigated for consistent behavioral differences at the individual level, referred to as animal personality. Fifteen individual Neogonodactylus oerstedii were tested in three scenarios designed to measure potential differences in behaviors: 1) exploration of a novel environment, 2) response to and recovery from a startling event, and 3) response to a novel object. Each individual went through the series of tests twice, with a …
