Pseudopterogorgia elisabethae is a known source of structurally interesting bioactive metabolites. A detailed search for new, related compounds was undertaken in this study which resulted in the isolation and characterization of more than ten new diterpenes with serrulatane and ileabethane skeletons. Some of the new compounds isolated are closely related terpenes with significant biological activity and others are likely to be key biosynthetic intermediates. As a component of the development...
Show morePseudopterogorgia elisabethae is a known source of structurally interesting bioactive metabolites. A detailed search for new, related compounds was undertaken in this study which resulted in the isolation and characterization of more than ten new diterpenes with serrulatane and ileabethane skeletons. Some of the new compounds isolated are closely related terpenes with significant biological activity and others are likely to be key biosynthetic intermediates. As a component of the development of a production method of anti-inflammatory compounds such as seco-pseudopterosin and elisabethadione, a synthesis of a seco-pseudoperosin aglycone from elisabethatriene was developed.

Marine sponges interact and coexist with many different organisms. A two-sponge association between Amphimedon erina and Geodia gibberosa commonly occurs in the Florida Keys. Previous studies have only focused on the ecological influence of the association; they did not examine the cellular basis of the association.

Show moreMarine sponges interact and coexist with many different organisms. A two-sponge association between Amphimedon erina and Geodia gibberosa commonly occurs in the Florida Keys. Previous studies have only focused on the ecological influence of the association; they did not examine the cellular basis of the association. This association between A. erina and G. gibberosa was used in the development of an in vitro model to further the understanding of the cellular basis of natural sponge-sponge associations. In this study, sponge cells were cultured individually and in co-cultures and their responses related to apoptosis, cell death, and proliferation were monitored using high content imaging. Co-cultured cells of species that form sponge-sponge associations did not have the same cellular responses compared to co-cultured cells of species that do not form sponge-sponge associations. Protein expression analyses demonstrated that the model that was established does not mimic the cellular response of the association in nature, but this model can be used to test in vitro cellular interactions of sponge species that do not form associations in nature. In addition, the protein expression data that were obtained revealed that sponges use similar apoptotic pathways as humans and suggest that sponge cells may shut down cell cycling in order to repair damaged DNA. This research is a small piece to the puzzle that is sponge cell culture research.

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

It can be difficult to disentangle the factors that determine population success in freshwater systems, particularly for organisms with disturbance-resistant life stages like aquatic invertebrates. Nevertheless, the effects of environmental variation and habitat structure on animal population success in wetlands are important for understanding both trophic interactions and biodiversity.

Show moreIt can be difficult to disentangle the factors that determine population success in freshwater systems, particularly for organisms with disturbance-resistant life stages like aquatic invertebrates. Nevertheless, the effects of environmental variation and habitat structure on animal population success in wetlands are important for understanding both trophic interactions and biodiversity. I performed two experiments to determine the factors limiting crayfish (Procambarus fallax) and dragonfly (Family: Libellulidae) populations in wetland environments. A simulation of a dry-disturbance and subsequent sunfish (Family: Centrarchidae) re-colonization revealed that crayfish populations are sensitive to sunfish, while dragonfly naiads seemed to be limited by other drying-related factors. A second manipulation revealed that small-bodied fishes and habitat structure (submerged vegetation) shaped dragonfly communities primarily through postcolonization processes.

The bathymetry and benthic environments of the study locality on the north-western margin of the Great Bahama Bank are discussed. A zoogeographic analysis indicates that the gastropod fauna in the vicinity of Victory Cay, Bimini Chain, Bahamas has a strong tropical affinity with a moderate influence from the temperate waters to the north.

The presence of heavy metals and other pollutants is detrimental to marine ecosystems. The queen conch, once an important fisheries species in the Florida Keys, has not sufficiently recovered after a 25-year fishery closure. Research has shown high levels of copper and zinc in the gonads and digestive glands of adult conch found in the nearshore waters. Four sites relevant to queen conch larval recruitment were tested in 2010 for the presence of copper and zinc in the water, phytoplankton,...
Show moreThe presence of heavy metals and other pollutants is detrimental to marine ecosystems. The queen conch, once an important fisheries species in the Florida Keys, has not sufficiently recovered after a 25-year fishery closure. Research has shown high levels of copper and zinc in the gonads and digestive glands of adult conch found in the nearshore waters. Four sites relevant to queen conch larval recruitment were tested in 2010 for the presence of copper and zinc in the water, phytoplankton, sediment, and seagrass epiphytes over seven months. Both metals were detected in all sample types and no seasonal or geographical differences were detected. Surface water concentrations from the field were used to conduct acute and chronic toxicity tests on various ages of queen conch larvae and their phytoplankton food source. When zinc concentrations (0-40 (So(Bg/L) similar to those measured in situ were used, there was no significant impact on conch larval survival although some velar lobe de velopment was impaired. However, field concentrations of copper (0-15 (So(Bg/L), which often surpassed water quality standards, negatively impacted growth, survival, and development of the larvae. Chronic exposure to copper, through the water and food, disrupted the metamorphic success of competent larvae and decreased post-metamorphosis survival. Exposure to copper at later life stages increased mortality, suggesting that heavy metals have a negative effect on larval recruitment in localized areas of the Florida Keys. Structural equation modeling revealed that copper and zinc are moving through the systems differently and are best represented by two different models.
