Movement, Behavior, And Trophic Ecology Of A Pelagic Predator Guild In The Eastern Tropical Pacific Ocean, Ryan Keith Logan
Movement, Behavior, And Trophic Ecology Of A Pelagic Predator Guild In The Eastern Tropical Pacific Ocean, Ryan Keith Logan
All HCAS Student Capstones, Theses, and Dissertations
Pelagic apex predators exert strong influences on ecological communities, and often support valuable commercial or recreational fisheries worldwide. Yet, due to their rarity and pelagic lifestyle, many species, such as billfishes, have proven particularly difficult to study at resolutions necessary to define dynamics of recovery from fishery interaction, physical interaction with environmental features and prey exploitation, and competitive interactions among other billfish predators. This leads to a paucity of knowledge on billfish ecology and habitat use, and hinders management efforts. With the ever-improving and miniaturization of technology and oceanographic datasets, the ability to define and quantify these interactions of fish …

Impacts On Fast-Start Performance: How Do Group Size And Habitat Degradation Alter The Escape Behavior Of A Schooling Coral Reef Fish?, Monica D. Bacchus

Escaping predation is essential for species survival, but prey must effectively match their response to the perceived threat imposed by a predator. Fish evaluate their surroundings using several sensory stimuli, including olfactory, visual, auditory, and mechanical cues. A range of taxa use the fast-start response to evade predators, including fishes, sharks, and larval amphibians. While the fast-start response (rapid bursts of swimming) is extensively studied in solitary fishes, the factors that mediate the collective escape response in schools of fish have historically been investigated far less. To address this knowledge gap, the collective escape behavior and individual escape performance of …
Optimization Of Grow-Out Of Bouldering Coral Microfragments: Land Vs. Offshore Nursery, Ashlee A. Steinberg
Optimization Of Grow-Out Of Bouldering Coral Microfragments: Land Vs. Offshore Nursery, Ashlee A. Steinberg
All HCAS Student Capstones, Theses, and Dissertations
Corals along the Florida Reef Tract and the wider Caribbean have been declining for decades. Low densities of adult colonies hinder the ability of corals to replenish themselves through sexual reproduction, thus reef managers are focusing on restoration actions that increase coral biomass. Microfragmentation is a way to quickly increase the biomass of bouldering corals by cutting the coral into small pieces which forces the coral to allocate its resources away from reproduction and back into growth, increasing its growth rate. This study assessed the optimal location for grow-out (land vs. offshore nursery) and its synergy with size of fragment …
