Title: Diet variation and the consumptive effects of native centrarchids on benthic macroinvertebrates in wetlands.
Creator: Bransky, Jacob., Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description: Fish predation can have structuring effects in aquatic communities, but the most important fish predators are not always immediately obvious. Generalist fish predators often occupy similar habitats and consume similar prey making determination of their consumptive impacts difficult. Understanding these consumptive impacts is important for understanding complex wetland food webs. I collected warmouth (Lepomis gulosus), bluespotted sunfish (Enneacanthus gloriosus), and dollar sunfish (Lepomis...
Show moreFish predation can have structuring effects in aquatic communities, but the most important fish predators are not always immediately obvious. Generalist fish predators often occupy similar habitats and consume similar prey making determination of their consumptive impacts difficult. Understanding these consumptive impacts is important for understanding complex wetland food webs. I collected warmouth (Lepomis gulosus), bluespotted sunfish (Enneacanthus gloriosus), and dollar sunfish (Lepomis marginatus) in two seasons from sloughs for both diet and bioenergetics analysis. Macroinvertebrates dominated diets of the three species, and nonparametric analyses revealed evidence of diet ontogeny in warmouth and potential competition for prey items among gape-matched individuals. Bioenergetics modeling revealed high levels of macroinvertebrate comsumption by these species relative to macroinvertebrate reproductive output suggesting that when combined with other sources of mortality, consumptive pressures placed by sunfish on benthic macroinvertebrates may be quite large.

Title: The Role of Chemical Cues in Locating Pelagic Sargassum by the Associated Fish Stephanolepis hispidus.
Creator: Cox, Derek, Brooks, W. Randy, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The ecosystem created by pelagic Sargassum is important in the life histories of a number of economically and ecologically important associated organisms. Fishes play a vital role in this food web and nutrient flow within these systems, but it is unknown how they locate these floating habitats. This study examined the role of natural chemical cues from Sargassum patches and the synthetic chemical Dimethylsulfonionpropionate (DMSP) for an associated fish, the planehead filefish (Stephanolepis...
Show moreThe ecosystem created by pelagic Sargassum is important in the life histories of a number of economically and ecologically important associated organisms. Fishes play a vital role in this food web and nutrient flow within these systems, but it is unknown how they locate these floating habitats. This study examined the role of natural chemical cues from Sargassum patches and the synthetic chemical Dimethylsulfonionpropionate (DMSP) for an associated fish, the planehead filefish (Stephanolepis hispidus) and a control fish species not associated with Sargassum, the masked goby (Coryphopterus personatus). Choice trials with a Y-maze apparatus determined that S. hispidus responded significantly to chemical cues from Sargassum while C. personatus did not. DMSP cues did not result in any significant behavioral responses for either fish. Demonstrating that S. hispidus can respond to chemical cues from Sargassum helps further our understanding of this unique floating algal reef and how fishes may locate it.

Title: Shifts in copepod grazing on varying concentrations of two bioluminescent dinoflagellate species.
Creator: Breitlow, Karen A., Florida Atlantic University, Widder, Edith A.
Abstract/Description: Grazing on bioluminescent and nonluminescent prey by the copepod Acartia tonsa was examined to determine the effect dinoflagellate bioluminescence has on copepod feeding preferences and rates. The percentage of cells ml-1 remaining after 30 minutes of copepod grazing on the dinoflagellates Lingulodinium polyedrum and Pyrodinium bahamense in their bioluminescent and nonbioluminescent phases was used to compare results for concentrations of 10, 1,000, and 3,000 cells ml-1.

Show moreGrazing on bioluminescent and nonluminescent prey by the copepod Acartia tonsa was examined to determine the effect dinoflagellate bioluminescence has on copepod feeding preferences and rates. The percentage of cells ml-1 remaining after 30 minutes of copepod grazing on the dinoflagellates Lingulodinium polyedrum and Pyrodinium bahamense in their bioluminescent and nonbioluminescent phases was used to compare results for concentrations of 10, 1,000, and 3,000 cells ml-1. The nonluminescent diatom Thalassiosira eccentrica was later offered along with each of the dinoflagellates. When diatoms were offered with P. bahamense, the copepods consumed them in equal amounts regardless of bioluminescence at the lower concentration, while the higher concentration showed decreased grazing with bioluminescence. Nonbioluminescent L. polyedrum was consumed at a high rate for all concentrations, but grazing decreased once they were bioluminescent. Copepods switched to T. eccentrica once the dinoflagellates became bioluminescent, except at 3,000 cells ml-1, at which all grazing was reduced. These results indicate there may be a threshold concentration separating two functions of dinoflagellate bioluminescence.

Title: The Role of Chemoreception and Host-Use on the Behavioral Ecology of the Pea Crab Tunicotheres moseri (Rathbun, 1918) in Tampa Bay, Florida.
Creator: Ambrosio, Louis J., Brooks, W. Randy, Florida Atlantic University

Cues affecting host use and host recognition in the West Florida population were the focus ofthis study. T. moseri responded to conspecific and host generated chemical cues in the water column. Although host generated chemical cues were recognized by T. moseri, tactile cues triggered much stronger responses to host ascidians. Results of conditioning trials suggest that T. moseri is a generalist in host use and accepts novel host species after conditioning with Molgula occidentalis and Phallusia nigra. However, T. moseri prefers S. plicata after conditioning with novel host species. The results of this study suggest that any genetic divergence existing between geographically disjunct populations of T. moseri are probably due to limited dispersal potential rather than population specific host fidelity and host use characteristics.

Title: Nutrition and habitat driven foraging of wild dolphins in the Bahamas: a recipe for prey.
Creator: Malinowski, Christopher R., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Two sympatric dolphin species, Stenella frontalis and Tursiops truncatus, resident to Little Bahama Bank, Bahamas were found to mostly forage independent of one another, but occasionally foraged in mixed groups. Analysis of over 20 years of data revealed the degree of overlap to be minimal with spatially distinct regions identified for both species, environmental segregation based on depth, bottom type, temperature, and time of day.

Show moreTwo sympatric dolphin species, Stenella frontalis and Tursiops truncatus, resident to Little Bahama Bank, Bahamas were found to mostly forage independent of one another, but occasionally foraged in mixed groups. Analysis of over 20 years of data revealed the degree of overlap to be minimal with spatially distinct regions identified for both species, environmental segregation based on depth, bottom type, temperature, and time of day. Results based on observational data indicated significant differences in group size and selected prey. For S. frontalis, lactating females had the most distinct diet, which differed from that of non-reproductively active (NRA) females. Pregnant females had ambiguous prey use results, but diet differences were revealed through nutritional analysis. Lactating females had a higher intake of all nutrients (% moisture, % lipid, % protein, and calories) than pregnant females but lower than NRA females. Mother and calf pairs selected prey for caloric and moisture values. The influence of calves on foraging groups was reflected through discrete differences in all nutrients. Males and females appeared to select the same major prey, but female prey use was much more diverse.

Show moreAtlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus) are two sympatric species resident to the Bahamas. The visibility of the Bahamian water provided a unique opportunity to study spotted dolphin communication during aggression. This study’s main focus was to decipher any similarities or differences in the behaviors used by spotted dolphins during interspecific and intraspecific aggression. Both similarities and differences were discovered. Biting, following, and chasing behavioral events were used more during interspecific aggression, while the display behavioral class was used more than the contact behavioral class during intrabut not interspecific aggression. This study showed that spotted dolphins use more energy intensive and risky behaviors when fighting interspecifically. This could result from having to fight and defend females from a larger species, trying to avoid sexual harassment from bottlenose males, or needing to use behaviors that are more overt and easily understood during interspecies communication.

Show morePersistent, anthropogenic contaminants collectively known as endocrine-disrupting chemicals (EDCs), are considered to be potential threats to wildlife reproductive fitness (Wingfield, 2002). The modes by which EDCs act on the reproductive system, and establishment of steroid profiles in wildlife, are important areas of study. Two means of performing an endocrine snapshot profile from dolphin tissues (serum and urine) were tested on samples, comparing a novel high performance liquid chromatography method to newly-validated enzyme-linked immunoassays (ELISAs). Serum and urine samples were obtained from two marine parks, and from free-ranging dolphins in the Indian River Lagoon (IRL) and Charleston Harbor (CHS) systems. Relative binding affinities of steroids versus putative EDCs to steroid receptors were compared in dolphin reproductive tissues, obtained by the Georgia Aquarium's Dolphin Conservation Field Station (GADCFS) from strained bottlenose dolphins (four male, three female) during 2010 and 20ll.........I conclude that endocrine disruptors are tissue and receptor specific, and both legacy and emerging contaminants are of concern to dolphin stocks, particularly those facing other significant environmental stressors.

Title: Snapping shrimp protect host anemones from predators.
Creator: McCammon, Amber., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The sea anemone Bartholomea annulata, is an ecologically important member of Caribbean coral reefs. This anemone serves as symbiotic host to crustacean associates, some of which may control parasite loads by "cleaning" reef fishes. Associates may gain protection from predation by dwelling with anemones. B. annulata was the most abundant anemone documented on three reefs, with 52% host to crustacean symbionts. Of those occupied by multi-species groups, 92% included Alpheus armatus shrimp. A....

Of those occupied by multi-species groups, 92% included Alpheus armatus shrimp. A. armatus is an important anemone associate providing protection to the anemone from predators such as Hermodice carunculata, in laboratory and field trials. H. carunculata can completely devour or severely damage prey anemones. Here I show that anemones hosting symbiotic alpheid shrimp are extremely less likely to sustain damage by predators than solitary anemones. The role of protector may be reciprocally provided by anemone and decapod associates.

This study compares and contrasts the development of flippers in sea turtle (Caretta caretta) and penguin (Spheniscus demersus , Eudyptula minor) embryos. Embryos were fixed, cleared and stained for cartilage anlagen, and prepared as whole mounts. Skeletal elements forming the flipper and changes in their growth rates were described across developmental stages. Results suggest skeletal elements contribute differently to sea turtle and penguin flipper blades and there are significant differences in bone shape and growth patterns. Greater proportional increases in lengths and areas were found in sea turtles elements compared to penguins. Sea turtles appear to depend on a pathway resulting in elongation of distal elements to build a flipper, whereas penguin limbs undergo flattening and expansion of fewer elements to meet a similar structural goal.

Polychaete annelids and peracarid crustaceans were the numerically most important initial colonizers of the new pit, together comprising 91.8% of the fauna. Species diversity (H') and equitability were lowest during the first sampling period (4.21 and 0.82, respectively) and, although variable, increased toward the end of the study (5.10 and 0.92, respectively). The disturbed area showed complete recovery based on several aspects of community structure, although differences in species composition were still evident between the new and old pits.

Show moreRecently, there has been an increase in marine mammal mortalities, most commonly Atlantic bottlenose dolphins, Tursiops truncatus, which is an alarming indication of the health status of the marine ecosystem. Studies have demonstrated that some free-ranging dolphins exhibit a suppressed immune system possibly because of exposure to contaminants or infectious microorganisms. However, this research has been limited due to a lack of commercially available marine-specific antibodies. Therefore, the first chapter of this thesis aims to identify cross-reactive terrestrial-specific antibodies that could be used to phenotype and compare the immune cell populations of dolphins under human care and free-ranging dolphins. The second chapter aims to utilize terrestrial-specific growth factors and dendritic cell (DC) surface markers to generate, characterize, and compare ex vivo DCs from peripheral blood mononuclear cells (PBMCs) of dolphins under human care and free-ranging dolphins. In summary, I have identified differences within the PBMCs and ex vivo generated DCs of dolphins under human care and free-ranging dolphins that could potentially shed light on the impact of environmental contaminants and infectious microorganisms on immune cells which could lead to increased morbidity and mortality.

Show moreThis project tested the effects of water conditions on developmental rates of larvae of the estuarine sea anemone Nematostella vectensis . Egg masses were collected immediately following fertilization and placed in solutions with different salinities and maintained in a temperature-controlled water bath. Every twelve hours, embryonic development was checked for progression through different morphological stages of development. Comparison of regression analyses of larval development at each temperature increment indicated that both temperature and salinity affected the rate of development; development was slower in lower conditions and faster at higher salinities and temperatures, with extreme conditions inducing deleterious effects. The suggested ideal conditions for these larvae are a salinity range of 12.5--20% and a temperature range of 22--24C. These parameters provide a foundation from which a standardized testing method may be established, using N. vectensis larval development.
