Title: Prey selectivity of the fishes Stephanolepis hispidus and Histrio histrio on the Sargassum shrimps Latreutes fucorum and Leander tenuicornis.
Creator: Hutchinson, Kimberly A., Florida Atlantic University, Brooks, W. Randy
Abstract/Description: Predator-prey relationships were studied between the shrimps Latreutes fucorum and Leander tenuicornis and the predatory fishes Stephanolepis hispidus and Histrio histrio, all found within pelagic Sargassum communities. Average survival times of shrimps were compared in species, size/density, and habitat selection studies. The results showed that S. hispidus had a preference for prey species while H. histrio did not. 30 mm shrimp survived longer than the 10 mm shrimp for both S. hispidus and...
Show morePredator-prey relationships were studied between the shrimps Latreutes fucorum and Leander tenuicornis and the predatory fishes Stephanolepis hispidus and Histrio histrio, all found within pelagic Sargassum communities. Average survival times of shrimps were compared in species, size/density, and habitat selection studies. The results showed that S. hispidus had a preference for prey species while H. histrio did not. 30 mm shrimp survived longer than the 10 mm shrimp for both S. hispidus and H. histrio. Density was a factor in the survival times of the 20 mm shrimps with S. hispidus only. L. tenuicornis survived longer in artificial Sargassum habitats with H. histrio. The larger shrimps survived longer in the artificial habitats than the smaller shrimps with S. hispidus. Both fish predators employ optimal foraging strategies with similarities and differences, the latter of which are likely related to behavioral differences in the these predator and prey.

Show moreThe pseudopterosins and seco-pseudopterosins are diterpene glycosides isolated from the marine octocoral Pseudopterogorgia elisabethae . These compounds exhibit potent anti-inflammatory and analgesic properties superior to the industrial standard indomethacin. The overall goal of this work was to complete biosynthetic studies for the development of a biotechnological production method of the pseudopterosins and seco-pseudopterosins. The aim of this project was to identify all intermediates involved in pseudopterosin biosynthesis. Previously, the Kerr lab has shown that elisabetatriene and erogorgiaene are the first two committed steps in pseudopterosin biosynthesis. In a continuation of those metabolic studies, the isolation and utilization of 7-hydroxyerogorgiaene, 7,8-dihydroxyerogorgiaene, seco-pseudopterosin J, amphilectosins A and B in pseudopterosin biosynthesis is reported. The utilization of these compounds in pseudopterosin biosynthesis was assessed by incubating these compounds in radiolabeled form with viable cell-free extracts of P. elisabethae and monitoring for the incorporation of a radiolabel in the pseudopterosins. We also report the isolation of the pseudopterosin aglycone from extracts of P. elisabethae and identified the aglycone as the end product of this metabolic pathway.

Title: Nematocyst replacement in the sea anemone Aiptasia Pallida following predation by Lysmata Wurdemanni: an inducible defense?.
Creator: Jennings, Lucas, Laramore, Susan E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The sea anemone Aiptasia pallida is a biological model for anthozoan research. Like all cnidarians, A. pallida possesses nematocysts for food capture and defense. Studies have shown that anthozoans, such as corals, can rapidly increase nematocyst concentration when faced with competition or predation, suggesting that nematocyst production may be an induced trait. The potential effects of two types of tissue damage, predator induced (Lysmata wurdemanni) and artificial (forceps), on nematocyst...
Show moreThe sea anemone Aiptasia pallida is a biological model for anthozoan research. Like all cnidarians, A. pallida possesses nematocysts for food capture and defense. Studies have shown that anthozoans, such as corals, can rapidly increase nematocyst concentration when faced with competition or predation, suggesting that nematocyst production may be an induced trait. The potential effects of two types of tissue damage, predator induced (Lysmata wurdemanni) and artificial (forceps), on nematocyst concentration was assessed. Nematocysts were identified by type and size to examine the potential plasticity associated with nematocyst production. While no significant differences were found in defensive nematocyst concentration between shrimp predation treatments versus controls, there was a significant difference in small-sized nematocyst in anemones damaged with forceps. The proportions of the different types of nematocysts between treatment types were also found to be different suggesting that nematocyst production in A. pallida is a plastic trait.

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...

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: Assessment of multiple paternity for the queen conch, Strombus gigas.
Creator: Harris, Chris., Harriet L. Wilkes Honors College
Abstract/Description: The commercially important queen conch, Strombus gigas, has been observed copulating with multiple partners and laying multiple egg masses during a reproductive season (Randall, 1964). While multiple paternity has been confirmed using microsatellite based genetic analysis for a variety of other gastropods, this technique has not been employed for S. gigas. Determining whether or not this species is capable of multiple paternity is important to understanding and maintaining genetic diversity...

While multiple paternity has been confirmed using microsatellite based genetic analysis for a variety of other gastropods, this technique has not been employed for S. gigas. Determining whether or not this species is capable of multiple paternity is important to understanding and maintaining genetic diversity of natural and captive populations. While an assessment of multiple paternity is the ultimate goal of this study, for my thesis, I have completed preliminary work which includes perfecting methods of tissue collection, DNA extraction, and DNA amplification with six non-labeled polymorphic microsatellite molecular markers, using cultured Strombus gigas animals. In addition, I collected tissue and extracted DNA from three wild S. gigas adult females and their egg masses from Pelican Shoal in the Florida Keys.

Title: Discovery of Loxosomella vivipara (Entoprocta: Loxosomatidae) in the Marine Sponge Hippospongia cf. gossypina (Porifera: Spongiidae) in the Florida Keys.
Creator: Plunkett, Rachel, Pomponi, Shirley A., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Populations of a marine invertebrate symbiont were found on the outer surface and internal spaces of a keratose sponge from a shallow bay in the Florida Keys in May 2014. A total of 24 specimens of the seagrass and reef-dwelling sponge were collected between May 2014 and August 2015 to provide material to identify both host and symbiont, and elucidate information on the nature of the association. Based on a morphological analysis via light microscopy, histology, and scanning electron...
Show morePopulations of a marine invertebrate symbiont were found on the outer surface and internal spaces of a keratose sponge from a shallow bay in the Florida Keys in May 2014. A total of 24 specimens of the seagrass and reef-dwelling sponge were collected between May 2014 and August 2015 to provide material to identify both host and symbiont, and elucidate information on the nature of the association. Based on a morphological analysis via light microscopy, histology, and scanning electron microscopy (SEM), and 99% similarity in aligned partial sequences from 28S and 18S nuclear ribosomal genes (rDNA), the symbiont was identified as the solitary entoproct Loxosomella vivipara Nielsen, 1966 (Entoprocta: Loxosomatidae). A partial sequence from the Internal Transcribed Spacer Region 2 (ITS2) of L. vivipara was registered to GenBank for the first time. The identity of the host sponge, based on a morphological investigation, is resolved as “velvet sponge” Hippospongia cf. gossypina Duchassing and Michelotti, 1864 (Demospongiae: Spongiidae). This is the first report of an entoproct commensal from Hippospongia cf. gossypina, a sponge that formerly had great commercial value when it was abundant throughout the Bahamas, Florida Keys and Gulf of Mexico. Other common sponge species at the study site were collected to investigate the host specificity of L. vivipara. Evidence that L. vivipara favorably selects the sponges Hippospongia cf. gossypina and Chondrilla nucula over other potential host sponges at the study site is provided. Commensalism is the most plausible justification for this relationship: L. vivipara is dependent on sponges for protection and food particles, while the sponges are unaffected by its presence. Further evidence of host-specific inquilinism is provided for L. vivipara associated with Hippospongia cf. gossypina, but not for L. vivipara associated with C. nucula. An inquilinistic association between an entoproct and sponge is a rare discovery only mentioned in one previous study. Sponge aquiferous qualities such as aperture and canal size, canal and choanocyte chamber arrangement, seawater pumping rate, and food particle size selection are likely factors that inhibit or enable inquilinism in sponge-entoproct associations – a potential topic for future researc
