Title: Biosynthetic studies of the antitumor ecteinascidins in the marine tunicate Ecteinascidia turbinata.
Creator: Miranda, Neil Fermino, Florida Atlantic University, Kerr, Russell G.
Abstract/Description: Ecteinascidin is a tetrahydroisoquinoline alkaloid isolated from the colonial ascidian Ecteinascidia turbinata. Ecteinascidin exhibits tremendous activity against P388 murine leukemia, however its yields from the tunicate are as low as 10^-4%. A biosynthetic investigation, using in vivo and in vitro methods, has resulted in the identification of the metabolic precursors of ecteinascidin as tyrosine, DOPA and cysteine. Reactive intermediates such as tyrosine and DOPA diketopiperazines have...

Show moreMasking or decorator crabs, conceal themselves partially through camouflage, by selecting or indiscriminately attaching materials from their environment to their exoskeleton. Functional aspects of decorating behavior and morphology in this group have not been documented. Using Microphrys bicornutus as a model species, this dissertation demonstrates clearly that decorating is an advantageous phenotype that has evolved to serve several functions. Decorating is a complex behavior that begins when a crab approaches an algal substrate and results in the attachment of algae to hooked setae on the exoskeleton. Once decorated, crabs remain motionless on the substrate until disturbed or until another behavior is initiated. This was confirmed for M. bicornutus, as crabs spent a significant amount of time feeding, remaining motionless, picking, and walking when compared to decorating. Crabs displayed agonistic behaviors during encounters with conspecifics conspecifics. These included both active aggressive behavior and display behavior. Crabs showed a decrease in motility during these encounters, helping maintain dispersed distributions, thereby decreasing intrsapecific encounters in the field. Trials were done to determine the effect of conspecifics, predators and feeding preferences on algal utilization. M. bicornutus showed a significant decrease in the amount of algae used for decoration in the highest density trials (i.e., 4 and 8 crabs). Agonistic displays and aggressive behavior between these crabs likely affected the time available for decorating. Decorated crabs isolated from an algal substrate were more likely to survive in the presence of either of two sympatric fish predators. Thus, being protected by the algal decoration on their exoskeletons. Trials also showed a parallel between algal consumption and algal materials used for decoration. In addition to its protective function, algae used by M. bicornutus for decoration simultaneously serve as short term food supplies for the crabs. Eleven morphologically complex structures were identified and mapped on the exoskeleton. Hooked setae were the primary structures used to attach algae to the crab’s body. Ten additional setal structures were present, including two novel types of setae. On the basis of location and morphological variation exhibited among these latter structures, a primary sensory function may be inferred.

Show moreThe wahoo, Acanthocyhium solandri, is a pelagic marine fish which inhabits tropical, subtropical, and warm temperate waters worldwide. Despite being highly mobile and economically important over most of their range, there is little scientific data concerning population structure, movement patterns, or environmental preferences of wahoo. In this study I investigate wahoo genetic population structure and phytogeography on a global scale, and deploy pop-up satellite archival tags (PSA T's) in the western Atlantic Ocean to determine movement patterns and environmental preferences of wahoo. Wahoo population genetic structure was examined across their entire global range with intron six of lactate dehydrogenase-A (ldhA6, 10 locations, N = 213) and mtDNA cytochrome h (Cyth, 13 locations, N = 322). Results show extensive sharing ofhaplotypes and no significant structure between all locations (mtDNA ~ST < 0.0001, P = 0.634; nuclear FsT = 0.0125, P = 0.1 06). Overall nuclear heterozygosity (H = 0.714) and mtDNA haplotype diversity (h = 0.918) are both high, while overall mtDNA nucleotide diversity (n = 0.006) and nuclear nucleotide diversity (n = 0.004) are uniformly low. Coalescence indicates an effective female population size CNeF) at - 816,000, and a population bottleneck - 690,000 years ago. Movement patterns and environmental preferences were investigated by deploying PSA T's onto four individual wahoo in the western Atlantic Ocean. Tagging success rate (75%) validates the deployment protocol developed for this project. Results indicate that wahoo in the western Atlantic ocean spend the greatest portion of their time between 0 and 20 meters of depth, and between temperatures of 20oC and 26°C. More time was spent near the deeper extremes of their range during the nocturnal period, and daily visits to the surface were observed. Wahoo were observed traveling north in Fall and Winter, contrary to previous notions concerning the migratory movements of this species. The genetic results indicate a worldwide stock for wahoo, which reinforces the mandate for international cooperation on fisheries issues. The PSA T results demonstrate the value of the acquired data to the investigation of important life history parameters in pelagic species. The information generated from this project will benefit fisheries managers, marine biologists, evolutionary biologists, and both commercial and recreational fishing interests.

Title: Productivity and Nutrition of Sargassum: A Comparative Ecophysiological Study of Benthic and Pelagic Species in Florida.
Creator: Feibel, Alison, Lapointe, Brian E., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description: Benthic algal species receive elevated nitrogen (N) and phosphorus (P) availability as anthropogenic activities increase the loading of nutrients into coastal waters. Pelagic species could also be responding to this nutrient enrichment. This study compared the tissue nutrient content and productivity of three benthic and two pelagic species of Sargassum. We hypothesized that the benthic species would have a higher tissue nutrient content and productivity than the pelagic species and the...
Show moreBenthic algal species receive elevated nitrogen (N) and phosphorus (P) availability as anthropogenic activities increase the loading of nutrients into coastal waters. Pelagic species could also be responding to this nutrient enrichment. This study compared the tissue nutrient content and productivity of three benthic and two pelagic species of Sargassum. We hypothesized that the benthic species would have a higher tissue nutrient content and productivity than the pelagic species and the pelagic species would have a higher tissue nutrient content and productivity than historic data. The tissue nutrient content and net productivity of the benthic and pelagic species were not significantly different indicating that the pelagic species are receiving high levels of nutrient availability comparable to that of the benthic species. Pelagic species in the current study exhibited significantly higher N:P ratios and net productivity than the historic data, suggesting a shift from N to P limitation and increased productivity.

Title: Shifts in copepod grazing on varying concentrations of two bioluminescent dinoflagellate species.
Creator: Breitlow, Karen A., Florida Atlantic University, Widder, Edith A.
Abstract/Description: Grazing on bioluminescent and nonluminescent prey by the copepod Acartia tonsa was examined to determine the effect dinoflagellate bioluminescence has on copepod feeding preferences and rates. The percentage of cells ml-1 remaining after 30 minutes of copepod grazing on the dinoflagellates Lingulodinium polyedrum and Pyrodinium bahamense in their bioluminescent and nonbioluminescent phases was used to compare results for concentrations of 10, 1,000, and 3,000 cells ml-1. The nonluminescent...

The percentage of cells ml-1 remaining after 30 minutes of copepod grazing on the dinoflagellates Lingulodinium polyedrum and Pyrodinium bahamense in their bioluminescent and nonbioluminescent phases was used to compare results for concentrations of 10, 1,000, and 3,000 cells ml-1. The nonluminescent diatom Thalassiosira eccentrica was later offered along with each of the dinoflagellates. When diatoms were offered with P. bahamense, the copepods consumed them in equal amounts regardless of bioluminescence at the lower concentration, while the higher concentration showed decreased grazing with bioluminescence. Nonbioluminescent L. polyedrum was consumed at a high rate for all concentrations, but grazing decreased once they were bioluminescent. Copepods switched to T. eccentrica once the dinoflagellates became bioluminescent, except at 3,000 cells ml-1, at which all grazing was reduced. These results indicate there may be a threshold concentration separating two functions of dinoflagellate bioluminescence.

Show moreMuch of the world's oceans lie below a depth of 200 meters, but very little is known about the creatures that inhabit these deep-sea environments. The deep-sea fish family Melamphaidae (Stephanoberyciformes) is one such example of an understudied group of fishes. Samples from the MAR-ECO (www.mar-eco.no) project represent one of the largest melamphaid collections, providing an ideal opportunity to gain information on this important, but understudied, family of fishes. The key to the family presented here is the first updated, comprehensive key since those produced by Ebeling and Weed (1963) and Keene (1987). Samples from the 2004 MAR-ECO cruise and the U.S. National Museum of Natural History provided an opportunity to review two possible new species, the Scopelogadus mizolepis subspecies, and a Poromitra crassiceps species complex. Results show that Scopeloberyx americanus and Melamphaes indicoides are new species, while the two subspecies of Scopelogadus mizolepis are most likely o nly one species and the Poromitra crassiceps complex is actually several different species of Poromitra. Data collected from the MAR-ECO cruise provided an opportunity to study the distribution, reproductive characteristics and trophic ecology of the family Melamphaidae along the Mid-Atlantic Ridge (MAR). Cluster analysis showed that there are five distinct groups of melamphaid fishes along the MAR. This analysis also supported the initial observation that the melamphaid assemblage changes between the northern and southern edges of an anti-cyclonic anomaly that could be indicative of a warm-core ring. Analysis of the reproductive characteristics of the melamphaid assemblage revealed that many of the female fishes have a high gonadosomatic index (GSI) consistent with values found for other species of deep-sea fishes during their spawning seasons., This may indicate that melamphaids use this ridge as a spawning ground. Diets of the melamphaid fishes were composed primarily of ostracods, a mphipods, copepods and euphausiids. Scopelogadus was the only genus shown to have a high percent of gelatinous prey in their digestive system, while Melamphaes had the highest concentration of chaetognaths. This work presents data on the ecology and taxonomy of the family Melamphaidae and provides a strong base for any future work on this biomass-dominant family of fishes.
