- Abstract/Description

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. 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...
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.

Reefs off the coast of Florida face threats from stressors associated with climate change which leads to phase shifts. Under rapid climate change, a clear understanding of how reefs and their benthic organisms respond is still lacking and needs to be investigated.

Show moreReefs off the coast of Florida face threats from stressors associated with climate change which leads to phase shifts. Under rapid climate change, a clear understanding of how reefs and their benthic organisms respond is still lacking and needs to be investigated. Using in situ imagery, a sponge cell model, and long-term benthic biota surveys, the effects of climate change on reef dynamics were explored in this dissertation project. Results from the in situ imagery found that differences in spectral signatures are found between functional groups (i.e., corals, sponges, and algae) and different species from substrate. Results based on a sponge cell model and transcriptomics data have found a resilience of these sponges to the predicted thermal extremes. Results from benthic biota surveys suggested that depth and light attenuation have the largest influence on the predicted distribution of corals, sponges, and algae at Pulley Ridge. Climate change has been impacting reef benthic biota starting at the organismal scale up to the reef scale. This research demonstrates the importance of monitoring reefs at a finer scale and determining the thresholds and limits of benthic biota to projected thermal extremes to better inform resource managers to preserve these irreplaceable ecosystems.

Show moreThis paper is a result of the taxonomic analyses of the sponges collected during the NOAA Ship Pisces expeditions in 2018 and 2019 with the University of North Carolina, Wilmington (UNCW) Mohawk ROV. This is part of a 9-year project conducted by NOAA National Marine Fisheries (NMF) in collaboration with the Cooperative Institute for Ocean Exploration, Research, and Technology (CIOERT) at Harbor Branch Oceanographic Institute, Florida Atlantic University (HBOI-FAU) to document and monitor the Marine Protected Areas (MPAs) of the southeastern U.S. continental shelf (eastern Florida to North Carolina, 50-165 m deep). The most prominent and conspicuous sponges were collected with the intention of evaluating the biodiversity of this important benthic group in these mesophotic habitats. Eleven sponge samples were collected, and taxonomic evaluation, studying the internal and external morphology, resulted in: 1) three well recognized species from the Tropical Western Atlantic (Leiodermatium lynceus, Neofibularia nolitangere, Clathria foliacea), 2) four species with sibling recognized species but with major morphological differences that might require the description of new species (Epipolasis cf. profunda, Cliona cf. tumula, Cliona aff. celata), and 3) three species that only could receive generic assignations (Penares sp.1, Clathria sp.1, and Aaptos sp.1). These results show that more than half of the species collected represent unknown species to science, or unknown variations of recognized species. Careful comparison with species types and observations of spicules under SEM would allow the necessary evidence to characterize and classify these new species or varieties. We suggest further characterization of these novel fauna considering their level of abundance and distribution in the MPAs studied. A synoptic description of each species studied, with live, deck and microscopy photographs is here presented.

- Abstract/Description

Mesophotic coral reef ecosystems (MCEs) are light-dependent benthic communities that occur deeper than shallow reefs and typically range from depths of 30 m to the bottom of the photic zone, which may extend to >150 m in some regions. MCEs represent in part an extension of shallow-water coral reef ecosystems and support a diverse assemblages of habitat-building taxa, including corals, sponges and algae, and associated fish (Reed et al., 2018). Many MCEs worldwide appear to be thriving...
Show moreMesophotic coral reef ecosystems (MCEs) are light-dependent benthic communities that occur deeper than shallow reefs and typically range from depths of 30 m to the bottom of the photic zone, which may extend to >150 m in some regions. MCEs represent in part an extension of shallow-water coral reef ecosystems and support a diverse assemblages of habitat-building taxa, including corals, sponges and algae, and associated fish (Reed et al., 2018). Many MCEs worldwide appear to be thriving compared to shallow reefs. The deep reef refugia hypothesis suggests that MCEs may be less impacted from natural and anthropogenic impacts than shallow coral reefs, and may be more stable and resilient than shallow reefs. MCEs may also act as refugia for shallow reef species through the export of fish and coral larvae. However, it is now apparent that MCEs are also vulnerable to disturbances from all facets of perturbations including climate change, bottom trawling, invasive species, and pollution. Whereas considerable data have been reported regarding the distribution, ecology, and health of Cuba’s shallow reefs, relatively little is known about the distribution, community structure and health of Cuba’s deep mesophotic reefs. Cuba’s strong marine policies and legislation has already resulted in 105 MPAs, covering nearly 25% of its insular shelf, yet overfishing, poaching, pollution and global warming are threats to these vulnerable ecosystems, as reefs worldwide are threatened.

Marine sponges are one of the most prolific sources of chemical compounds with pharmaceutical importance. To establish a supply of such compounds large enough for clinical development, in vitro production methodology was investigated.

To establish a supply of such compounds large enough for clinical development, in vitro production methodology was investigated. Since all sponge cells do not divide in culture, it was hypothesized that the fusion of rapidly dividing cells of a sponge that does not produce any compounds of interest with cells of a nondividing but compound-producing sponge would result in a hybridoma that produces the compound of interest. In this study, hybridomas have been produced with cells of two marine sponges, Axinella corrugata, which produces the antitumor compound stevensine, and Geodia neptuni, which divides rapidly in a nutrient medium optimized for sponge cell culture. Successful hybridization and subsequent cell division and in vitro stevensine production may unlock the potential for sustainable mass production of other sponge-derived compounds.
