Evaluating Recruitment Seasonality Of Red Abalone (Haliotis Rufescens) To Inform Fisheries Management And Conservation Policy, Leslie Christine Hart
Master's Theses
Recruitment, the addition of new individuals to a population, must be understood to make predictions about population growth of marine invertebrates. Red abalone (Haliotis rufescens) represent a former important commercial fishery in California, and until recently, supported a major recreational fishery. However, there have been statewide declines since the 1960s due to overfishing, disease, and climatic factors. Thus, understanding population dynamics to inform management and population restoration is critical. Recruitment dynamics of red abalone are poorly understood, with no prior knowledge of seasonal trends. To address this knowledge gap, I assessed monthly (July 2016-June 2017) and annual (2012-2016) …

Outplanting Technique, Host Genotype, And Site Affect The Initial Success Of Outplanted Acropora Cervicornis, Elizabeth Goergen, David S. Gilliam
Marine & Environmental Sciences Faculty Articles
Acropora cervicornis is the most widely used coral species for reef restoration in the greater Caribbean. However, outplanting methodologies (e.g., colony density, size, host genotype, and attachment technique) vary greatly, and to date have not been evaluated for optimality across multiple sites. Two experiments were completed during this study, the first evaluated the effects of attachment technique, colony size, and genotype by outplanting 405 A. cervicornis colonies, from ten genotypes, four size classes, and three attachment techniques (epoxy, nail and cable tie, or puck) across three sites. Colony survival, health condition, tissue productivity, and growth were assessed across one year …

The Easter Island ecoregion includes Rapa Nui (Easter Island; RN), with a human population of ~5600, and the uninhabited Salas y Gómez (SyG). Although the culture and terrestrial ecology of RN have been well studied, we know little about the marine environment of these islands, particularly the interplay among herbivores, algae, and corals, and how coral reef communities differ between islands, by wave energy exposure, and between depths. To address the potential roles of herbivores, wave-energy exposure, and depth on the sessile benthic communities, we examined herbivorous fish biomass, sea urchin (Diadema savignyi) density, and algal and coral …

Coral Reef Fishes Exhibit Beneficial Phenotypes Inside Marine Protected Areas, Robert Y. Fidler, Jessica Fidler, Kristen W. Rynerson, Danielle F. Matthews, Ralph G. Turingan
Ocean Engineering and Marine Sciences Faculty Publications
Human fishing effort is size-selective, preferentially removing the largest individuals from harvested stocks. Intensive, size-specific fishing mortality induces directional shifts in phenotypic frequencies towards the predominance of smaller and earlier-maturing individuals, which are among the primary causes of declining fish biomass. Fish that reproduce at smaller size and younger age produce fewer, smaller, and less viable larvae, severely reducing the reproductive capacity of harvested populations. Marine protected areas (MPAs) are extensively utilized in coral reefs for fisheries management, and are thought to mitigate the impacts of size-selective fishing mortality and supplement fished stocks through larval export. However, empirical evidence of …

Journal of Marine Science and Technology–Taiwan
The proximate composition, pH, free amino acids, ammonia and nucleotide-related compounds of raw abalone, commercial processed abalone and abalone analogues were investigated. Taurine was the dominant free amino acid (FAA), accounting for 61.4% of the total FAA in raw hybrid abalone and 29.9% in processed abalone. Abalone analogue products had a high amount of free amino acids, but only 0.3-2.5% taurine. The proximate composition and pH value of abalone changed only slightly after blanching and processing, while the taurine and glycogen content decreased by 50%. FAA profiles were significantly different between commercial processed abalone and analogue products, both of which …

Journal of Marine Science and Technology–Taiwan
Many marine organisms have developed the capability of producing unique metabolites and thus are highly likely to contain anti-infective agents. This study was conducted to investigate extracts of three seaweeds (Caulerpa racemosa, Caulerpa sertularioides, Kappaphycus alvarezii), two soft corals (Lobophytum microlobulatum, Sarcophyton auritum) and a marine sponge (Spheciospongia vagabunda) collected from Malaysian coast for antibacterial, antifungal, antiviral and cytotoxic activities. The samples were subjected to sequential solvent extraction in order to obtain hexane, chloroform, ethyl acetate, ethanol, methanol and water extracts. The antibacterial and antifungal activities were studied using a colorimetric broth microdilution method. The hexane extract of L. microlobulatum …

Towards An Integrated Storm Surge And Wave Forecasting System For Taiwan Coast, Yeayi Peter Sheng, Vladimir Alexander Paramygin, Chuen-Teyr Terng, Chi-Hao Chu
Journal of Marine Science and Technology–Taiwan
This paper describes the application of a coupled surge-wave model for simulating storm surge and wave along Taiwan coast. The simulations were conducted with an integrated surge-wave modeling system using a large coastal model domain wrapped around the island of Taiwan, with a grid resolution of 50-400 m. Simulations were made with tide only, with wind and tide, and with tide and wind and wave. The first part of the paper describes the hindcasting of historical typhoons. Hindcasting of Soudelor in 2015 revealed the significant effect of waves on storm surge when wave exceeded 11 m. Both the water level …

DEEPEND Datasets
The deep sea ecosystem is believed to contain the highest biomass of fish in the oceans. However, the taxonomic diversity in this ecosystem is incompletely described and likely to be vastly underestimated. DNA sequence data (barcodes) have become a key tool to discover hidden biodiversity. We generated mitochondrial DNA barcode datasets based on the Cytochrome c oxidase I (COI) gene from deep sea fishes. These data were analyzed using phylogenetic and statistical methods to reveal cryptic species and make taxonomic linkages between adult fishes and their early life stages. These datasets were generated from fishes collected in the northern Gulf …

Research outputs 2014 to 2021
Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.
Here, we explore the stress physiology of two coexisting kelps undergoing opposing range shifts in the Northeast Atlantic and discuss what differences in stress physiology may mean for future niche filling.
We used chlorophyll florescence (Fv/Fm) and differentiation of the heat shock response (HSR) to determine the capacity of the expanding kelp, Laminaria ochroleuca, to move …

No More Reason For Ignoring Gelatinous Zooplankton In Ecosystem Assessment And Marine Management: Concrete Cost-Effective Methodology During Routine Fishery Trawl Surveys, A. Aubert, E. Antajan, C. Lynam, S. Pitois, A. Pliru, S. Vaz, D. Thibault
Student Publications
Gelatinous zooplankton, including cnidarians, ctenophores, and tunicates (appendicularians, pyrosomes, salps and doliolids), are often overlooked by scientific studies, ecosystem assessments and at a management level. Despite the important economic consequences that they can have on human activities and on the marine food-web, arguments often related to the costs of monitoring or their coordination, or simply negligence, have resulted in the absence of relevant monitoring programs. A cost-effective protocol has been applied on trawling from existing fishery surveys conducted by national laboratories in England and France. The testing phase has successfully demonstrated the adequacy of such a tool to sample …

Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits in trophic interactions between sharks found in different habitats. We show that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional …

Convergent Evolution Of Biochemical Innovations In Polychaetes: Characterizing The Molecular Basis Of Bioluminescence And Venom Production, Aida E. Verdes Gorín
Dissertations, Theses, and Capstone Projects
The convergent evolution of phenotypic traits is a widespread phenomenon across the tree of life and is explained as the outcome of different taxa facing similar selective forces or environmental conditions. A longstanding question in evolutionary biology is whether the evolution of convergent phenotypes in unrelated lineages is driven by similar or different molecular processes. The research presented here investigates this question by characterizing the molecular basis of two biochemical innovations, bioluminescence and venom production, that have evolved independently in different lineages of polychaetes worms (Annelida). We use an integrative approach, combining next-generation sequencing, phylogenetics and computational tools to evaluate …

Rare Parthenogenic Reproduction In A Common Reef Coral, Porites Astreoides, Alicia A. Vollmer
HCNSO Student Theses and Dissertations
Multiple stressors have caused a decline in coral populations. Broadcast spawning corals once dominated the Florida Reef Tract (FRT), but since their decline, smaller brooding corals, soft corals, and macroalgae are replacing them. Brooding corals are more resilient to current threats in part because they are reproductive throughout much of the year and their larvae are competent to settle after release. Despite the ubiquity of brooders on Florida reefs, much of their reproductive strategy remains unknown. This study aimed to examine paternity as a function of colony size and density in Porites astreoides, a common brooding coral in the …

Marine & Environmental Sciences Faculty Articles
The damping of short gravity-capillary waves (Bragg waves) due to surfactant accumulation under low wind speed conditions results in the formation of natural sea slicks. These slicks are detectable visually and in synthetic aperture radar satellite imagery. Surfactants are produced by natural life processes of many marine organisms, including bacteria, phytoplankton, seaweed, and zooplankton. In this work, samples were collected in the Gulf of Mexico during a research cruise on the R/V F.G. Walton Smith to evaluate the relative abundance of Bacillus spp., surfactant-associated bacteria, in the sea surface microlayer compared to the subsurface water at 0.2 m depth. A …

We use a spatially explicit biogeochemical end-to-end ecosystem model, Atlantis, to simulate impacts from the Deepwater Horizon oil spill and subsequent recovery of fish guilds. Dose-response relationships with expected oil concentrations were utilized to estimate the impact on fish growth and mortality rates. We also examine the effects of fisheries closures and impacts on recruitment. We validate predictions of the model by comparing population trends and age structure before and after the oil spill with fisheries independent data. The model suggests that recruitment effects and fishery closures had little influence on biomass dynamics. However, at the assumed level of oil …

Despite the speculations that jellyfish (hydromedusae, siphonophores, scyphomedusae and ctenophores) may compete with forage fish for prey, there are few direct comparisons of their diets. To determine the dietary overlap between Aurelia sp. (Cnidaria, Scyphozoa) and Brevoortia patronus (Goode, 1878) (Pisces, Clupeidae) in the northern Gulf of Mexico, we collected monthly samples in Louisiana, Mississippi and Alabama coastal waters (USA) during summer and early fall 2009−2010. We determined carbon and nitrogen stable isotope ratios in predators and their potential prey, including small plankton (<200 µm) and mesozooplankton (200− 2000 µm), and identified prey in the stomachs of adult Aurelia sp. and B. patronus. Trophic niche overlap was defined using the stable isotope Bayesian …
