Exploring The Potential For Artificial Reefs In Coral Reef Restoration: Responses And Interactions Of Associated Biota To Varying Experimental Treatments In The Mexican Caribbean, Audie Kirk Kilfoyle Mar 2017

Exploring The Potential For Artificial Reefs In Coral Reef Restoration: Responses And Interactions Of Associated Biota To Varying Experimental Treatments In The Mexican Caribbean, Audie Kirk Kilfoyle

HCNSO Student Theses and Dissertations

Coral reefs are being negatively impacted by various causes worldwide, and direct intervention is often warranted following disturbance to restore or replace lost ecosystem structure and function. An experimental coral reef restoration study involving standardized artificial reef modules (ReefballsTM) was conducted in Mexico’s Yucatan Peninsula in the towns of Puerto Morelos and Akumal. The purpose was to explore the use of artificial structure for restoration and mitigation applications in a highly diverse and dynamic Caribbean coral reef environment by applying and evaluating the performance of select experimental treatments hypothesized to accelerate development of the associated biota. The first …

A Comparison Of The Ichthyofaunal Trophic Ecology At Selected Limestone Artificial Reef Sites And Adjacent Natural Reef Sites, Joseph R. Hornbeck Mar 2017

A Comparison Of The Ichthyofaunal Trophic Ecology At Selected Limestone Artificial Reef Sites And Adjacent Natural Reef Sites, Joseph R. Hornbeck

HCNSO Student Theses and Dissertations

Artificial reefs may enhance the biological production of reef-associated flora and fauna, but their trophic structure relative to that of natural reefs remains understudied. We assessed trophic dynamics by comparing δ13C and δ15N in 43 fish species from artificial and natural reef tracts of Broward County, Florida. We tested the effect of sampling location (artificial, first, and second reef), general feeding strategy (herbivore, omnivore, planktivore, invertivore, and carnivore), phylogeny, and standard length. For all samples, δ13C and δ15N ranged from -19.5 to -13.1‰ and 6.7 to 13.3‰, respectively. Lower trophic level feeding …

The Phenology Of Sand Crabs, Lepidopa Benedicti (Decapoda: Albuneidae), Zen Faulkes Mar 2017

The Phenology Of Sand Crabs, Lepidopa Benedicti (Decapoda: Albuneidae), Zen Faulkes

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Albuneid sand crabs are widespread on sandy beaches around the world, but because they conceal themselves by digging in sand and are often found at low densities, little is known about their basic biology. Lepidopa species were collected from the beaches of South Padre Island, Texas, on the western coast of Gulf of Mexico, a location that had previously been suggested to act as a population sink. The site contained Lepidopa benedicti and L. websteri, although the latter was extremely rare (collected three times in 5 years). There was significant variation in abundance across the year, with higher densities …

Nematocyst Distribution Corresponds To Prey Capture Location In Hydromedusae With Different Predation Modes, Marco Corrales-Ugalde, Sean Colin, Kelly R. Sutherland Mar 2017

Nematocyst Distribution Corresponds To Prey Capture Location In Hydromedusae With Different Predation Modes, Marco Corrales-Ugalde, Sean Colin, Kelly R. Sutherland

Arts & Sciences Faculty Publications

Understanding the factors that control predation in pelagic communities can inform predictions of community structure in marine ecosystems. Ubiquitous and selective predators such as cnidarian hydromedusae rely on their nematocysts to capture and retain prey but it is not clear how the density and spatial distribution of these cells relate to predation mode. We examined the relationship between prey capture and nematocyst distribution in the tentacles of Aglantha digitale and Proboscidactyla flavicirrata, which are considered ambush predators, and Clytia gregaria and Mitrocoma cellularia, which are considered feeding-current predators. First, we analyzed video of predator-prey interactions to compare capture locations of …

The Relationship Between Near Shore Hardbottom Exposure And Benthic Community Composition And Distribution In Palm Beach County, Fl, Kristen A. Cumming Mar 2017

The Relationship Between Near Shore Hardbottom Exposure And Benthic Community Composition And Distribution In Palm Beach County, Fl, Kristen A. Cumming

HCNSO Student Theses and Dissertations

Anthropogenic changes to the landscape, storm events and sea level rise are contributing to the erosion of beaches leading to an increase of the sediment load in near shore marine environments. Palm Beach, Florida is host to unique near shore hardbottom habitats. These areas are distinct from the vast expanses of surrounding sediments and play and important role of habitat and shelter for many different species. In this study, remotely sensed images from 2000-2015 were used to look at the movement of sediment and how it contributes to exposure rates of near shore hardbottom habitats in Palm Beach, Florida and …

Plasma Metabolites Reveal Changes In Physiological State Of Eared Grebes (Podiceps Nigricollis) During Three Non-Migratory Periods, Allison A. Yoshida Mar 2017

Plasma Metabolites Reveal Changes In Physiological State Of Eared Grebes (Podiceps Nigricollis) During Three Non-Migratory Periods, Allison A. Yoshida

Theses

Energy storage and use during the annual cycle of migratory birds is dynamic especially during migration. However, considerable amounts of the annual cycle are spent not migrating, and the physiological state of birds during these non-migratory periods is not well understood. We compared plasma metabolites (TRIG, BUTY, URIC, GLY) in Eared Grebes (Podiceps nigricollis) residing at three important areas when they are not migrating: fall staging (postbreeding at Mono Lake, California), spring staging (pre-breeding at Great Salt Lake, Utah), and an extended stopover prior to spring staging (Salton Sea, California). Plasma metabolites were also measured in resting and active grebes …

The Insulin-Like Growth Factor-1 (Igf1) System As A Potential Biomarker For Nutritional Status And Growth Rate In Pacific Rockfish (Sebastes Spp.), Nicole L. Hack Mar 2017

The Insulin-Like Growth Factor-1 (Igf1) System As A Potential Biomarker For Nutritional Status And Growth Rate In Pacific Rockfish (Sebastes Spp.), Nicole L. Hack

Master's Theses

Growth performance in vertebrates is regulated by environmental factors including the quality and quantity of food, which influences growth via endocrine pathways such as the growth hormone (GH) / insulin-like growth factor somatotropic axis. In several teleost fishes, circulating concentrations of insulin-like growth factor-1 (Igf1) correlate positively with growth rate, and it has been proposed that plasma Igf1 levels may serve as an indicator of growth variation for fisheries and aquaculture applications. Here, I tested whether plasma Igf1 concentrations might serve as an indicator of somatic growth in olive rockfish (Sebastes serranoides), one species among dozens of rockfishes …

Turning Performance Of Brief Squid Lolliguncula Brevis During Attacks On Shrimp And Fish, Rachel A. Jastrebsky, Ian K. Bartol, Paul S. Krueger Mar 2017

Turning Performance Of Brief Squid Lolliguncula Brevis During Attacks On Shrimp And Fish, Rachel A. Jastrebsky, Ian K. Bartol, Paul S. Krueger

Biological Sciences Faculty Publications

Although squid are generally considered to be effective predators, little is currently known of how squid maneuver and position themselves during prey strikes. In this study, high-speed video and kinematic analyses were used to study attacks by the brief squid Lolliguncula brevis on both shrimp and fish. Squid attack successwas high (>80%) and three behavioral phases were identified: (1) approach, (2) strike and (3) recoil. Lolliguncula brevis demonstrated greater maneuverability (i.e. a smaller length-specific turning radius) and employed more body adjustments (i.e. mantle angle posturing) during approaches toward shrimp versus fish. Squid exhibited higher linear approach/strike velocities and accelerations …

A Multivariate Mixed Hidden Markov Model For Blue Whale Behaviour And Responses To Sound Exposure, Stacy L. Deruiter, Roland Langrock, Tomas Skirbutas, Jeremy A. Goldbogen Mar 2017

A Multivariate Mixed Hidden Markov Model For Blue Whale Behaviour And Responses To Sound Exposure, Stacy L. Deruiter, Roland Langrock, Tomas Skirbutas, Jeremy A. Goldbogen

University Faculty Publications and Creative Works

Characterization of multivariate time series of behaviour data from animal-borne sensors is challenging. Biologists require methods to objectively quantify baseline behaviour, and then assess behaviour changes in response to environmental stimuli. Here, we apply hidden Markov models (HMMs) to characterize blue whale movement and diving behaviour, identifying latent states corresponding to three main underlying behaviour states: shallow feeding, travelling, and deep feeding. The model formulation accounts for inter-whale differences via a computationally efficient discrete random effect, and measures potential effects of experimental acoustic disturbance on between-state transition probabilities. We identify clear differences in blue whale disturbance response depending on the …

Diversity Of Deep-Sea Fishes Of The Easter Island Ecoregion, Erin E. Easton, Javier Sellanes, Carlos F. Gaymer, Naiti A. Morales, Matthias Gorny, Eric Berkenpas Mar 2017

Diversity Of Deep-Sea Fishes Of The Easter Island Ecoregion, Erin E. Easton, Javier Sellanes, Carlos F. Gaymer, Naiti A. Morales, Matthias Gorny, Eric Berkenpas

School of Earth, Environmental, & Marine Sciences Faculty Publications

The Easter Island Ecoregion is in the center of the South Pacific gyre and experiences ultra-oligotrophic conditions that could make it highly susceptible to global change and anthropogenic activities, so it is imperative that these regions are characterized and studied so that conservation and sustainable management strategies can be developed. From the few studies from the region, we know that the coastal areas are relatively depauperate and have relatively high rates of endemism. Here, we present a brief report from the first video observations from this region of the deep-dwelling fishes from ROV exploration of benthic communities from …
