Animal Movement, Stable Isotopes, Telemetry, Habitat Use, Nutrient Enrichment

Date of Defense



Habitat selection by organisms can be driven by a number of factors, including the availability of resources. In particular, nutrient enrichment can alter the quality of landscapes, and thus the availability of resources, with implications for consumer movement and habitat use. In coastal ecosystems, eutrophication can affect the production and distribution of resources, and thus the behaviors and space use of consumers. In this study, I coupled acoustic telemetry methods and stable isotope analyses (SIA) to examine the effects of nutrient enrichment on the movement, habitat use, and resource use of Common Snook (Centropomus undecimalis), a valuable recreational fishery, across two neighboring estuarine lake systems of varying trophic state (eutrophic vs. mesotrophic), located in Florida Bay (Florida, USA). This thesis work highlights the value of cross-site comparisons that pair movement and trophic measurements to improve our understanding of how animals select habitats under varying environmental conditions and production regimes.
