The coral reefs within Indonesia’s Wakatobi Marine National Park support a high diversity of reef-building hard corals and associated marine fish. Climate change threatens to dramatically affect coral reef ecosystems by altering the interactions between reef fish and the specific microhabitats they depend on for survival. To examine the spatially varied effects of habitat complexity on the community composition and trophic structure of marine fish assemblages, I analyzed fish community and habitat complexity data across reef zones. Habitat complexity metrics were: structural complexity, the percentage of hard coral (HC) cover, HC genera richness, HC genera diversity (Shannon index), and HC …

The goals of my thesis are to: 1) identify species of bats in Wright State University’s (WSU) campus woods via acoustic surveys to compare to detections from previous years (Chapter 1) (2) analyze occupancy and detection probabilities of Indiana bats in different areas throughout the woods (Chapter 1), and 3) create an acoustical approach to analyze habitat use through bat social calls (Chapter 2). In Chapter 1, I conducted stationary acoustic surveys in the Wright State University woods in hydric (riparian), edge, and old growth habitats to record bat vocalizations. The WSU woods have a diverse bat community as ten …

In this study, I examined how the spatiotemporal distribution of spider webs and diet changed in a lake riparian zone with increasing distance from an aquatic resource. I surveyed twenty, one-hundred meter transects along the perimeters of Sanford and Escanaba lakes (Wisconsin). Overall, spider web abundance was highest near the lakes and decreased moving into the adjacent forest. Horizontal orb webs, vertical orb webs, and mesh webs showed strong negative relationships with distance from the lakes. Aquatic insects composed an average 36-64% of spider diet for all spider families throughout the riparian zone, suggesting that some spider families are selecting …
