Finding Nemo's Place In A Complex Animal Society: An Exploration Of The Behavioural And Hormonal Correlates Of Dominance In Amphiprion Ocellaris, Eugene Cheung
Electronic Theses and Dissertations
Exploration of the mechanisms underlying conflict resolution has been key to our understanding of the dynamics driving the formation and organization of complex animal societies. This thesis examines the role of aggression and individual variation on dominance hierarchies and the correlates of expression of cortisol, 11-ketotestosterone, and testosterone on individual social status in novel size-matched Amphiprion ocellaris dominance hierarchies. Here, I report that greater aggressiveness relays higher dominance status during hierarchy establishment, as well as during experimental recruitment of highly aggressive smaller individuals into established groups. Additionally, I show that cortisol expression profiles are related to social status in both …
Assessing The Accuracy Of Fish-Based Indicators Of Biological Condition In Coastal Wetlands Of The Great Lakes, Jeffrey D. Buckley
Assessing The Accuracy Of Fish-Based Indicators Of Biological Condition In Coastal Wetlands Of The Great Lakes, Jeffrey D. Buckley
Electronic Theses and Dissertations
Assessing the quality of biological communities is important in the management of Great Lakes Coastal Wetlands. Biological indicator models can be used to quantify the condition of biotic communities. A number of biological indicators have been developed for use with fish communities in Great Lakes Coastal wetlands. The overall goal of this thesis was to assess the performance of various biological indicators in their ability to identify degradation in wetland fish communities. Biological indicators were assessed with respect to the disturbance gradient against which they was originally derived. Subsequently, the models' utility as diagnostic tools was assessed for use in …
