Colonization of a nearshore artificial reef at Boca Raton (Palm Beach County), Florida
Title
Colonization of a nearshore artificial reef at Boca Raton (Palm Beach County), Florida.
Creator
Cummings, Sandra Lee., Florida Atlantic University, Marsh, G. Alex
Abstract/Description
The Boca Raton artificial reef was designed to mitigate for the burial of nearshore rock habitat resulting from beach restoration. Seasonal recruitment and community development of the reef were studied from April 1988 to July 1990. Species diversity within the fish community reached an equilibrium 2-2.5 months following reef placement. Seasonality was recorded for juvenile, intermediate and adult life history stages. Encrusting invertebrates and algae exhibited preferences for vertical and...
Show moreThe Boca Raton artificial reef was designed to mitigate for the burial of nearshore rock habitat resulting from beach restoration. Seasonal recruitment and community development of the reef were studied from April 1988 to July 1990. Species diversity within the fish community reached an equilibrium 2-2.5 months following reef placement. Seasonality was recorded for juvenile, intermediate and adult life history stages. Encrusting invertebrates and algae exhibited preferences for vertical and horizontal substrates, respectively, while nonencrusting invertebrates exhibited no preference for surface orientation. No conspicuous seasonal trends were evident for the encrusting or non-encrusting invertebrates, except for Watersipora sp. and Botryllus schlosseri. Equilibrium was not attained by invertebrates or algae, nor was there evidence of true ecological succession beyond the earliest stages. Instead, the reef appeared to be maintained in an early stage of development as a result of frequent physical disturbance.

Abstract/Description
The effect of artificial reefs on natural reefs is poorly understood. This study focused on Aquarius Reef Base (ARB), an underwater habitat offshore of Key Largo, Florida, and 14 natural reef sites spanning 4 habitats, on the surrounding Conch Reef. Food web models were created for ARB and natural reef habitats. Biomass at each habitat was quantified by fish surveys. Using Ecopath, species were organized into functional groups with supporting data from previous research for other inputs. ARB...

This study focused on Aquarius Reef Base (ARB), an underwater habitat offshore of Key Largo, Florida, and 14 natural reef sites spanning 4 habitats, on the surrounding Conch Reef. Food web models were created for ARB and natural reef habitats. Biomass at each habitat was quantified by fish surveys. Using Ecopath, species were organized into functional groups with supporting data from previous research for other inputs. ARB’s food web was found to have a large predator biomass with insufficient prey biomass to sustain the population, suggesting that these predators must forage on nearby natural reefs where the predator/prey ratio is smaller. Between 0.57km2 and 1.79km2 of natural reef is estimated to be a sufficient spatial subsidy for the large predatory biomass at ARB when the biomass is added as determined by the seascape around the artificial reef.

Artificial reef morphology: Relationship to fish recruitment and community structure
Title
Artificial reef morphology: Relationship to fish recruitment and community structure.
Creator
Lea, Barbara Chudzik, Florida Atlantic University, Courtenay, Walter R. Jr., Bourne, Godfrey R., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Rock and coral reef fishes are known to select their habitat, and selection oftentimes involves the settlement of pelagic larval stages. Thus, I examined the short-term temporal relationship between artificial reef morphology and the composition of warm-water reef fish assemblages 30 m offshore of the Town of Palm Beach, Florida. Correlations were found between reef height and total fish abundance and species richness. Reef height was also correlated with log transformed numbers of juveniles....
Show moreRock and coral reef fishes are known to select their habitat, and selection oftentimes involves the settlement of pelagic larval stages. Thus, I examined the short-term temporal relationship between artificial reef morphology and the composition of warm-water reef fish assemblages 30 m offshore of the Town of Palm Beach, Florida. Correlations were found between reef height and total fish abundance and species richness. Reef height was also correlated with log transformed numbers of juveniles. Horizontal opening size showed an inverse correlation with species richness and a weak inverse trend with juvenile abundance. Furthermore, vertical openings were directly proportional to juvenile and total fish abundance, and to species richness. Piscivore abundance was weakly influenced by presence and dimensions of vertical crevices. Thus, artificial reefs with many varied-sized vertical crevices are most desirable for attracting juvenile warm-water reef fishes.

HISTOCHEMICAL AND ELECTRON MICROSCOPICAL STUDY OF A GORGONIAN CORAL INFECTED WITH A GREEN FILAMENTOUS ALGA

Abstract/Description
A symbiosis between a gorgonian coral, Pseudoplexaura flagellosa (Houttuyn) and a filamentous green alga results in spongy nodules on the coral host. Morphological and histochemical differences between the normal and algal-infected coral were studied, using transmission electron microscopy and histochemistry. The algal filaments located within the host skeleton are covered with skeletal laminae. The infected skeleton is structurally abnormal and only remants of the mesogleal region adjacent...
Show moreA symbiosis between a gorgonian coral, Pseudoplexaura flagellosa (Houttuyn) and a filamentous green alga results in spongy nodules on the coral host. Morphological and histochemical differences between the normal and algal-infected coral were studied, using transmission electron microscopy and histochemistry. The algal filaments located within the host skeleton are covered with skeletal laminae. The infected skeleton is structurally abnormal and only remants of the mesogleal region adjacent to the skeleton remain. Acidic mucopoly-saccharide substances are associated with these areas. Host granulocytes are located in the mesoglea adjacent to the infected skeleton. These cells release vesicles that attach to algal filaments extending into the tissue zone. These host cells also stain positively for tyrosine and polyphenols which are known to be associated with the production of Pseudoplexaura skeleton. Granulocytes coat the algae and secrete skeletal-like material about them, therefore, participating in an encapsulation mechanism in defense of the host.

Abstract/Description
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. 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.

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.
