AN INVESTIGATION INTO THE NURSERY EFFECT OF SELECT REEF FISHES ALONG THE SOUTHERN FLORIDA COAST
Title
AN INVESTIGATION INTO THE NURSERY EFFECT OF SELECT REEF FISHES ALONG THE SOUTHERN FLORIDA COAST.
Creator
Pressly, Andrew, Hindle, Tobin, Florida Atlantic University, Department of Geosciences, Charles E. Schmidt College of Science
Abstract/Description
The nursery effect is a process where juvenile fish utilize coastal habitats to help them survive before moving to their adult habitat. This process establishes an important link between marine ecosystems. This study examines the nursery effect and nursery habitat utilization in the Indian River Lagoon and Florida Bay systems, and the coral reefs adjacent to them. Quantitative and spatial techniques were utilized to identify patterns of presence and abundance and the size structure of select...
Show moreThe nursery effect is a process where juvenile fish utilize coastal habitats to help them survive before moving to their adult habitat. This process establishes an important link between marine ecosystems. This study examines the nursery effect and nursery habitat utilization in the Indian River Lagoon and Florida Bay systems, and the coral reefs adjacent to them. Quantitative and spatial techniques were utilized to identify patterns of presence and abundance and the size structure of select fish species. Spatial analyses were also used to investigate distribution patterns. Findings from this study suggest that several species utilize to a high degree the Indian River Lagoon and Florida Bay as nurseries. Furthermore, the abundance of adults on coral reefs is strongly connected to the presence of nurseries. This study has implications in fisheries management such as locating where juveniles of species develop. With such knowledge, better management plans could be implemented to ensure healthy fish stocks.

Perceived risk versus actual risk to sea-level rise: a case study in Broward County, Florida

Perceived risk versus actual risk to sea-level rise: a case study in Broward County, Florida.
Creator

Abstract/Description
Global climate change stressors downscale to specific local vulnerabilities, requiring customized adaptation strategies. Southeast Florida has a high likelihood of sealevel rise impact to due to the low-lying porous limestone geology. High risk is coupled with high exposure due to high-valued coastal properties, productive ecosystems, and dense populations. Coastal populations are particularly at risk due to erosion, inundation and storm surge, but interior populations are also susceptible to...
Show moreGlobal climate change stressors downscale to specific local vulnerabilities, requiring customized adaptation strategies. Southeast Florida has a high likelihood of sealevel rise impact to due to the low-lying porous limestone geology. High risk is coupled with high exposure due to high-valued coastal properties, productive ecosystems, and dense populations. Coastal populations are particularly at risk due to erosion, inundation and storm surge, but interior populations are also susceptible to rising water tables and extended periods of inundation. All of these impacts are amplified by sea-level rise. Robust sea-level rise adaptation options require significant economic costs. If perceived risk does not adequately line up with actual risk, lack of funds and preparation will prevent implementation of the most effective strategies.

Environmental siting suitability analysis for commercial scale ocean renewable energy: a southeast Florida case study
Title
Environmental siting suitability analysis for commercial scale ocean renewable energy: a southeast Florida case study.
Creator
Mulcan, Amanda, Hanson, Howard P., Hindle, Tobin, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
This thesis aims to facilitate the siting and implementation of Florida Atlantic University Southeast National Marine Renewable Energy Center (FAU SNMREC) ocean current energy (OCE) projects offshore southeastern Florida through the analysis of benthic anchoring conditions. Specifically, a suitability analysis considering all presently available biologic and geologic datasets within the legal framework of OCE policy and regulation was done. OCE related literature sources were consulted to...
Show moreThis thesis aims to facilitate the siting and implementation of Florida Atlantic University Southeast National Marine Renewable Energy Center (FAU SNMREC) ocean current energy (OCE) projects offshore southeastern Florida through the analysis of benthic anchoring conditions. Specifically, a suitability analysis considering all presently available biologic and geologic datasets within the legal framework of OCE policy and regulation was done. OCE related literature sources were consulted to assign suitability levels to each dataset, ArcGIS interpolations generated seafloor substrate maps, and existing submarine cable pathways were considered for OCE power cables. The finalized suitability map highlights the eastern study area as most suitable for OCE siting due to its abundance of sand/sediment substrate, existing underwater cable route access, and minimal biologic presence. Higher resolution datasets are necessary to locate specific OCE development locales, better understand their benthic conditions, and minimize potentially negative OCE environmental impacts.

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. Results from the in situ imagery found that differences in...
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.
