With the increase in the use of UAS (Unmanned Aerial Systems) for marine mammal research, there is a need for the development of methods of analysis to transform UAS high resolution video into quantitative data. This study sought to develop a preliminary method of analysis that would quantify and present a way to visualize the dynamics and relative spatial distribution and changes in distribution of bottlenose dolphins (Tursiops truncatus) in the waters of Turneffe Atoll, Belize. This approach employs a previously developed video tracking program ‘Keypoint Tracking’ that enables manual tracking of individual dolphins and the creation of …
Neurobehavioral And Gene Expression Effects Of Early Embryonic Methylmercury Exposure In Yellow Perch (Perca Flavescens) And Zebrafish (Danio Rerio) Larvae, Francisco Xavier Mora Zamorano
Neurobehavioral And Gene Expression Effects Of Early Embryonic Methylmercury Exposure In Yellow Perch (Perca Flavescens) And Zebrafish (Danio Rerio) Larvae, Francisco Xavier Mora Zamorano
Theses and Dissertations
Methylmercury (MeHg) is a pervasive and persistent neurotoxic environmental pollutant known to affect the behavior of fish, birds and mammals. The present study addresses the neurobehavioral and gene expression effects of MeHg in yellow perch (Perca flavescens) and zebrafish (Danio rerio) embryos. The rationale for this study originated from an interest to understand the behavioral and molecular phenotypes of environmental MeHg exposure in the yellow perch, an ecologically and economically relevant species of the North American Great Lakes region. Both MeHg and the yellow perch coexist in a common ecosystem: the North American Great Lakes. However, the effects of this …
