Coupling Telemetry And Stable Isotope Techniques To Unravel Movement: Snook Habitat Use Across Variable Nutrient Environments, Cody W. Eggenberger Nov 2019

Coupling Telemetry And Stable Isotope Techniques To Unravel Movement: Snook Habitat Use Across Variable Nutrient Environments, Cody W. Eggenberger

FIU Electronic Theses and Dissertations

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 …


Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill Mar 2017

Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill

FIU Electronic Theses and Dissertations

Fish distribution patterns and seasonal habitat use play a key role in the food web dynamics of aquatic ecosystems, including the Florida Everglades. In this study I examined the fine scale habitat shifts and movements of spotted sunfish, Lepomis punctatus across varying seasons and hydrologic conditions using in-situ field enclosures and Passive Integrated Transponder (PIT) systems. Data on fish use of three dominant Everglades marsh habitats and activity level were recorded continuously from January to August, 2015. Fish were more active and had the highest use of higher elevation habitats when water levels rose during an experimental reversal in mid-April. …
