Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer
Effects Of Trophic Relationships On Oyster Reef Restoration Success In The Mississippi Sound, Virginia Robin Fleer
Dissertations
Natural and anthropogenic changes resulting from altered hydrology, hurricanes, variable precipitation, and the BP oil spill have all taken their toll on oyster reefs in Mississippi. In response, oyster reef restoration efforts are currently underway within the Northern Gulf of Mexico. In order to understand why these efforts succeed or fail, it is crucial to consider predator-prey relationships within the context of the trophic dynamics of oyster reefs. Thus, for this dissertation study I integrated a multidisciplinary approach to understanding key trophic interactions affecting oyster recruitment, growth and survival, comprising field sampling, manipulative lab experiments, and individual-based modeling. Spat settlement …
Differential Use Of Two Warm-Water Effluents By The Florida Manatee (Trichechus Manatus Latirostris) And Temporal Distributions Throughout Broward County, Florida, Laura F. Eldredge
Differential Use Of Two Warm-Water Effluents By The Florida Manatee (Trichechus Manatus Latirostris) And Temporal Distributions Throughout Broward County, Florida, Laura F. Eldredge
HCNSO Student Theses and Dissertations
The threatened Florida manatee (Trichechus manatus latirostris) migrates seasonally to warm-water refugia throughout the state of Florida due to metabolic requirements from low thermal conductance. Broward County’s two power plant refugia, Port Everglades (PEP) and Lauderdale (LPP), are known heavily-utilized aggregation sites for the Atlantic sub-population. Broward County collected relative abundance counts via aerial surveys from 2004–2013 siting 31,418 manatees during 169 surveys within 18 defined waterway zones. Counts during manatee wintering seasons were significantly different from January 2005-March 2008 and November 2008-March 2013, likely related to flight path and frequency standardization. Mean percentage of adults (90.12%) to …

Increases in the spatial scale and intensity of activities that produce marine anthropogenic sound highlight the importance of understanding the impacts and effects of sound on threatened species such as marine turtles. Marine turtles detect and behaviorally respond to low-frequency sounds, however few studies have directly examined their behavioral responses to specific types or intensities of anthropogenic or natural sounds. Recent advances in the development of bio-logging tools, which combine acoustic and fine-scale movement measurements, have allowed for evaluations of animal responses to sound. Here, we describe these tools and present a case study demonstrating the potential application of a …
Time-Activity And Energy Budgets Of Eared Grebes (Podiceps Nigricollis) At Salton Sea, Samantha San Francisco
Time-Activity And Energy Budgets Of Eared Grebes (Podiceps Nigricollis) At Salton Sea, Samantha San Francisco
Theses
Time-activity budgets have been a widely accepted way of approximating the daily energy expenditure of many species, including waterbirds. For this study, focal animal sampling was used to study Eared Grebes (Podiceps nigricollis) at their post-wintering stopover site, Salton Sea. Daylight time-activity budgets were converted to energy budgets using energy equivalents for diving, preening, swimming, and resting on water developed for Eared Grebes previously by H. I. Ellis (1994). Post-wintering Eared Grebes arrive at Salton Sea in waves at differing times in the spring. As a result, there can be individuals in a variety of physiological states during …
The Effect Of Boat Type On Bottlenose Dolphin (Tursiops Trucatus) Behavior In The Mississippi Sound, Maria Zapetis
The Effect Of Boat Type On Bottlenose Dolphin (Tursiops Trucatus) Behavior In The Mississippi Sound, Maria Zapetis
Master's Theses
Increases in oceanic shipping are a global phenomenon, and a leading cause of concern for marine animal welfare. While it may be difficult to assess the effect of boat traffic on all species in all contexts, it is vital to report anthropogenic impacts where longitudinal data is available, and doubly so where a dearth of information exists. The purpose of this study is to describe how dolphin behavior changed in the presence of boats in the Mississippi Sound between 2006 and 2012, and more specifically, to detail how different boat types impacted dolphins’ behavioral states. This study is unique in …
Luminescent Syllid (Odontosyllis Sp.) Courtship Display Densities Vary Across Marine Habitats Around South Water Caye, Belize, Mitchel Mccloskey, Joshua Scheil, Gregory J. Sandland, Gretchen A. Gerrish
Luminescent Syllid (Odontosyllis Sp.) Courtship Display Densities Vary Across Marine Habitats Around South Water Caye, Belize, Mitchel Mccloskey, Joshua Scheil, Gregory J. Sandland, Gretchen A. Gerrish
Gulf and Caribbean Research
Bright—green luminescent clouds frequently occur at the surface of shallow waters of the Caribbean Sea. These clouds are produced by syllid polychaetes during courtship. Although temporal variation in the occurrence of these courtship displays has been documented throughout the diurnal and lunar cycle, other factors such as habitat type have not been well studied. In this study, we investigated how syllid courtship—display densities varied across 3 substrate types (grassbed, rubble and coral) over a 3 day period. In line with previous studies, we found that syllid courtship displays occurred over seagrass and rubble substrates; however, we also found that display …

In 2011, an intensive, multiple-gear, fishery-independent survey was carried out in the northern Gulf of Mexico (GOM) to collect comprehensive age and length information on Red Snapper Lutjanus campechanus. Based on this synoptic survey, we produced a spatial map of Red Snapper relative abundance that integrates both gear selectivity effects and ontogenetically varying habitat usage. Our methodology generated a spatial map of Red Snapper at a 10-km2 grid resolution that is consistent with existing knowledge of the species: Red Snapper occurred in relatively high abundances at depths of 50–90 m along the coasts of Texas and Louisiana and in smaller, …
Do Belugas (Delphinapterus Leucas), Bottlenose Dolphins (Tursiops Truncatus), & Pacific White-Sided Dolphins (Lagenorhynchus Obliquidens) Display Lateralized Eye Preference When Presented With Familiar Or Novel Objects?, Deirdre Yeater, Sara Guarino, Steve Lacy, Tricia Dees, Healther Hill

Lateralization of behaviors and information processing are common across species. Hypothesized to be crucial for more efficient responding to environmental stimuli, lateralization has been investigated for a number of topics. Cetaceans are proposed to be hemispheric specialists, given a small corpus callosum, complete decussation of the optic nerve, and the ability to respond to a different visual stimulus presented to each eye simultaneously. Research with cetaceans has shown strong biases in a number of behaviors, including swimming, foraging, social interactions, and responses to myriad visual stimuli. Given similar evolutionary pressures, different species of cetaceans should display similar lateralized preferences. Previous …
