Abstract/Description
Identification of dolphin prey is fundamental to understanding the ecological function of dolphins within the Indian River Lagoon (IRL), and useful in determining shared resources and associated health risks among dolphins and humans. This study utilized 62 images of dolphin prey documented during observed feeding behaviors from 2003 to 2015 to determine prey of significance. Dolphin prey were comprised of: 44% mullet (Mugil spp.), 11% jack (Caranx spp.), 10% pinfish (Lagodon sp.), and 6.5%...
Show moreIdentification of dolphin prey is fundamental to understanding the ecological function of dolphins within the Indian River Lagoon (IRL), and useful in determining shared resources and associated health risks among dolphins and humans. This study utilized 62 images of dolphin prey documented during observed feeding behaviors from 2003 to 2015 to determine prey of significance. Dolphin prey were comprised of: 44% mullet (Mugil spp.), 11% jack (Caranx spp.), 10% pinfish (Lagodon sp.), and 6.5% menhaden (Brevoortia spp.). The remaining 28.5% of prey were comprised of 11 genera, and no spatial or temporal differences among prey were found. The majority (87%) of the genera of fishes documented as dolphin prey are also targeted by local fisheries for human consumption, bait, and sport. Understanding the prey habits of this apex predator can be useful in determining management and conservation strategies for local fisheries and ecosystems, and identifying possible vectors for bioaccumulation of contaminants.

SPECIES RICHNESS, ABUNDANCE AND OCCURRENCE OF GRASSBED FISHES FROM JUPITER INLET, FLORIDA

SPECIES RICHNESS, ABUNDANCE AND OCCURRENCE OF GRASSBED FISHES FROM JUPITER INLET, FLORIDA.
Creator
SNYDER, DAVID BRANT., Florida Atlantic University
Abstract/Description
The fish communities of two seagrass habitats near Jupiter Inlet, Florida, were studied from April 1981 to March 1982 to determine species composition, abundance, richness and occurrence. Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch. The presence of young lutjanids, haemulids, serranids and...
Show moreThe fish communities of two seagrass habitats near Jupiter Inlet, Florida, were studied from April 1981 to March 1982 to determine species composition, abundance, richness and occurrence. Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch. The presence of young lutjanids, haemulids, serranids and sphyraenids indicates the role of this area as a nursery ground. Temporal patterns in species composition and abundance were examined through numerical classification. Species composition was more consistent over time than were corresponding abundances. Despite their proximity, the two sites exhibited differences in species composition and abundance. The role of biological, physical and historical factors are discussed in relation to the observed community patterns.

Grazing effects of herbivorous fishes and juvenile green turtles (Chelonia Mydas) on macroalgal communities
Title
Grazing effects of herbivorous fishes and juvenile green turtles (Chelonia Mydas) on macroalgal communities.

Abstract/Description
The impact of grazers on the primary production of marine ecosystems has largely been explored in tropical environments. A number of studies support theories on the functional importance of grazers in the community structure of coral reefs. However, large-bodied grazers, like juvenile green turtles, co-occur with herbivorous fishes in subtropical and tropical regions throughout the world and we know little about their combined impact on macroalgal communities and whether they compete for...
Show moreThe impact of grazers on the primary production of marine ecosystems has largely been explored in tropical environments. A number of studies support theories on the functional importance of grazers in the community structure of coral reefs. However, large-bodied grazers, like juvenile green turtles, co-occur with herbivorous fishes in subtropical and tropical regions throughout the world and we know little about their combined impact on macroalgal communities and whether they compete for macroalgal resources. My dissertation research was composed of four studies that were conducted simultaneously to further our understanding of plant/herbivore interactions in marine ecosystems. Studies were conducted at the Trident Basin, a non-public military facility within the Port Canaveral Inlet at Cape Canaveral, Florida, USA. The macroalgal study (Chapter 1), determined the spatial and temporal distribution of the macroalgal community. The foraging habits of juvenile green turtles were compared with the macroalgal abundance within the Basin and over time (Chapter 2). Selection ‘for’ specific macroalgal species (based on their availability in the macroalgae study) was used to determine the level of overlap and/or partitioning of resources among herbivorous fishes and juvenile green turtles (Chapter 3). The final empirical study (Chapter 4) measured the impact on thallus height, diameter and/or branching of macroalgae as well as the macroalgal community composition from caging experiments that excluded herbivorous fishes and juvenile green turtles. The algal community was predominantly composed of nine red and green macroalgal species that were persistent year-round. Grazer-resistant macroalgae were rarely observed. Green turtles foraged on many of these same macroalgae but also opportunistically foraged on flotsam, including anthropogenic debris (e.g., plastic). The gut content of the major herbivorous fishes in the community (Abudefduf saxatilis, Archosargus probatocephalus, Diplodus holbrooki, and Lagodon rhomboides) foraged as omnivores depending on where they were captured within the Basin area or their size. All herbivores showed selection for less abundant green algae (i.e., Ulva spp.). Results of the exclusion of juvenile green turtles and large herbivorous fishes in caging experiments suggest that grazing by these large-bodied herbivores had no impact on the composition of the macroalgal community and little impact on the morphological structure of the macroalgal species that were examined. Collectively these four studies contribute to a better understanding of how multiple grazers have evolved to forage in macroalgal communities without detrimental effects on their food resources.
