Applying Ecological Theory To Amphibian Populations To Determine If Wood Frogs (Lithobates Sylvaticus) Are Ideal And Free When Selecting Breeding Habitat, Taylor M. Braunagel
Applying Ecological Theory To Amphibian Populations To Determine If Wood Frogs (Lithobates Sylvaticus) Are Ideal And Free When Selecting Breeding Habitat, Taylor M. Braunagel
Masters Theses
Amphibian populations are declining globally due to a litany of factors including pollution, disease, climate change, and most importantly, habitat destruction. As most amphibian life histories involve their populations being recruitment limited, focusing on the mechanism behind breeding habitat selection will reveal useful cues that managers may use to increase abundance and breeding success. Though there are many theoretical models that describe the distribution of animals in response to a resource, the ideal free distribution (IFD) theory has not yet been applied to amphibian settling decisions. Through this application of the IFD, I have found that a population of wood …

Factors Affecting Green Turtle Foraging Ecology Across Multiple Spatial Scales, Elizabeth Rose Whitman
FIU Electronic Theses and Dissertations
The hierarchical levels at which resource selection occurs can have important consequences for individual and population energy budgets and structure the impacts of a forager on its ecosystem. Assessing factors affecting resource selection of large marine herbivores across scales is important because of their potentially large impacts on seagrass community dynamics and historical and current changes in their population sizes and those of their potential predators. I explored the factors (predation risk, resource abundance, quality and identity) affecting resource use of large marine herbivores (green turtles, Chelonia mydas) from the scale of habitat patches to forage species within patches. …
