Non-Lethal Predictors Of Organ Level Metal Contaminants In Central Florida Red-Shouldered Hawks, Jennifer Bouchenot
Non-Lethal Predictors Of Organ Level Metal Contaminants In Central Florida Red-Shouldered Hawks, Jennifer Bouchenot
Electronic Theses and Dissertations, 2020-
Elemental contaminants aggregate in the environment due to human activity and can induce detrimental physiological effects within organisms. Birds exhibit exceptional susceptibility to many pollutants and are popular biomonitoring agents throughout the world. Birds of prey are of special interest due to their substantial biomagnification potential. Lethal sampling of internal organs yields accurate contaminant measurements, but recent sampling trends are endeavoring towards non-destructive sampling such as feathers. This methodological shift stems from researchers' preference for less-regulated samples, enhanced animal welfare, and broadening the possible collaborative audience with simpler protocols. Unfortunately, investigations of feathers have shown that their accuracy is capricious …
A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones
A Mathematical Model For Predicting Animal Population Persistence On Fragmented Landscapes, Allyson Jones
Electronic Theses and Dissertations, 2020-
The effects of roads, buildings, and cities on animal populations are widespread and, often times, disastrous. These structures fragment animals' homes, inhibiting their ability to obtain essential resources and to reproduce. The question arises then: Under what circumstances can an animal population persist in a fragmented landscape? To attempt to answer this question, we present a spatially explicit reaction-diffusion model with varying growth and diffusion rates that incorporates animal behavior at points where habitats are fragmented for four different habitats. The outcome of extinction or persistence of the animal population is determined by examining the effects of changing parameters on …
Bird Abundance And Diversity And The Impact Of Oyster Reef Restoration On The Bird Community In Mosquito Lagoon, Florida, Usa, Jessica Copertino
Bird Abundance And Diversity And The Impact Of Oyster Reef Restoration On The Bird Community In Mosquito Lagoon, Florida, Usa, Jessica Copertino
Electronic Theses and Dissertations, 2020-
Birds are often used as indicators for biodiversity and ecosystem health. While birds have been monitored in other parts of the Indian River Lagoon (IRL), there has been little research on birds in Mosquito Lagoon (ML, the northernmost portion of the IRL). This thesis first examines the abundance and diversity of birds in ML by using two years of photographic observations to assess seasonal variations and the use of various habitat features by specific bird taxa. Abundance and species richness were highest in winter, while evenness and Simpson's diversity were highest in summer. Moreover, natural and artificial habitat features were …
