Predator-Prey Responses Of The Clamworm Alitta Succinea To Direct Interaction With Crabs And Chemical Cues, Shyann Mcclain, Gloria M. Massamba N'Siala

Knowledge and Creativity Expo

Predator–prey interactions in marine benthic systems can have important indirect effects mediated through environmental signaling. Predators can reveal their presence through the release of chemical cues, influencing the activity and feeding rates of other potential prey through non-consumptive effects, which may ultimately shape energy allocation and survival in targeted populations. Along the Atlantic coast of the United States, predatory crabs overlap spatially with polychaete prey such as the clamworm Alitta succinea, creating consistent predation pressure. This study will set up the experimental system needed to examine the physiological responses of clamworms to both direct and indirect predation cues under controlled …

Methane Consumption Rates By Coastal Virginia Beach Microbes, James R. Bailey Ii

Knowledge and Creativity Expo

This study measures whether microbial communities in the shallow coastal waters of Virginia Beach are capable of consuming methane in the water column. Using methane enrichment incubations and gas chromatography, we found no measurable methane oxidation of our samples over multi-day periods. These results suggest that these coastal waters may act as net sources of atmospheric methane.

Establishing Aquarium Systems And Care Protocols For Marine Invertebrates In The Department Of Biological Sciences At Odu, Magdalene R. Hamlin, Gloria Massamba N'Siala Ph.D.

Knowledge and Creativity Expo

Maintaining live animals in lab settings is useful for establishing a stock of specimens available for experimental studies without relying on continuous collection efforts. Previous aquarium systems utilized in the aquatic facility of the Department of Biological Sciences at ODU were suited for research on freshwater and marine vertebrates and were not designed for the care of marine invertebrates. This project aims to establish methods and protocols suitable for maintaining various marine invertebrates in a control laboratory setting. In the first stage of the project, the existing recirculation system and lab space will be reorganized and restructured to suit the …

The Influence Of Wind Speed On Phytoplankton Bloom Timing In Antarctica's 5 Regions, Majesti L. Cummings, Jessie S. Turners

Knowledge and Creativity Expo

Phytoplankton blooms form the foundation of the Antarctic marine food web and play a critical role in regional carbon cycling. Recent observations along the West Antarctic Peninsula indicate shifts in bloom phenology, the seasonal timing of biological events in nature, with accumulation seasons occurring later in recent decades. This study investigates how different variability in spring wind speed influences phytoplankton bloom start dates and peak dates across five ecological regions of the West Antarctic Peninsula.

Bloom timing is derived from 25 years of satellite-based chlorophyll-a observations, including annual start date and peak date. Wind speed data derived from atmospheric reanalysis …

Fisheries Occasional Publication No. 151 - Response To 2025 External Review Of Integrated Stock Assessments For Key Wa Demersal Indicator Stocks, Brett Crisafulli, Emily A. Fisher, Matias Braccini, Rubie Evans-Powell, Fabian I. Trinnie, Ainslie Denham, S. A. Hesp

Fisheries Occasional Publications

Consistent with national trends, the Department of Primary Industries and Regional Development (DPIRD) is transitioning to the globally recognised Stock Synthesis (SS) platform to support more robust, transparent, and internationally aligned assessments. To ensure this transition remains scientifically sound, DPIRD commissioned an independent expert review in 2025, following a previous review in 2024. The 2025 review was conducted by Professor André Punt and focused on integrated models for three key WA fish stocks: red emperor in the Kimberley, WA dhufish in the southern West Coast Bioregion, and sandbar shark at the statewide level. This publication summarises the findings and recommendations …

Fenced And Feral: Farming And Spread Of Flowerhorn (Amphilophus Spp.) In Lake Sampaloc, Philippines, Janice A. Ragaza, Hannah Nicole Gasmen

Environmental Sustainability

This study examines the spread and ecological impact of invasive Flowerhorn cichlids (Amphilophus spp.) in Lake Sampaloc, Philippines, driven by both accidental release and intentional aquaculture practices. Field observations and literature reveal that these highly adaptable and aggressive fish outcompete native species, contributing to biodiversity decline amid increasing pollution, eutrophication, and microplastic contamination. Their phenotypic plasticity allows them to thrive in degraded environments, further exacerbating ecological imbalance. While local communities have begun utilizing Flowerhorns for ornamental trade and potential aquafeed production, such practices risk reinforcing their proliferation. The study highlights the need for integrated management strategies combining biosecurity, pollution control, …

Fisheries Occasional Publication No. 150 - Response To 2024 External Review Of Integrated Stock Assessments For Key Wa Demersal Indicator Stocks, Rubie Evans-Powell, S. A. Hesp, Ainslie Denham, Emily A. Fisher, Rachel Marks, Fabian I. Trinnie, Brett Crisafulli

Fisheries Occasional Publications

In Western Australia (WA), stock assessments for key demersal species, including snapper and red emperor, have traditionally used bespoke integrated models developed in-house by the Department of Primary Industries and Regional Development (DPIRD). In line with other Australian jurisdictions, DPIRD is transitioning to Stock Synthesis (SS) as its primary platform for integrated stock assessments of WA finfish. To support this transition, DPIRD commissioned an independent expert review of recent integrated models applied to three demersal stocks. This publication responds to recommendations from Professor André Punt (University of Washington and CSIRO) in his 2024 review, which examined assessments for Pilbara red …

Widespread Decline In The Abundance Of Sea Cucumber Assemblages In Atolls Of The Protected Rowley Shoals, Northwestern Australia, Inês Leal, Claire L. Ross, Simone Strydom, Richard D. Evans, Thomas H. Holmes, Graham J. Edgar, John K. Keesing

Research outputs 2022 to 2026

The Rowley Shoals, off northwestern Australia, are renowned as a biodiversity hotspot. This remote system comprises three atolls, Clerke, Imperieuse and Mermaid, which in recent years have been increasingly targeted by illegal fishing, a pressure rising across the Indo-Pacific. The objective of this study was to quantify recent changes in sea cucumber assemblages across the Rowley Shoals. We surveyed nine sea cucumber species at monitoring sites in 2018 and 2023 to assess changes in their abundance. Total assemblage densities declined significantly across all atolls and habitats. Documented seizures of illegally harvested holothurians by the Australian Fisheries Management Authority over this …

Comparing Methods For Measuring 210po In Seawater: Fe(Oh)3 Can Extract Less 210po Than Co-Apdc And Thus Overestimate Poc Export Fluxes, Harold Carrasco, J. Kirk Cochran, Beat Gasser, Inés Sanz-Alvarez, Montserrat Roca-Martí, Christina Heilbrun, Nicholas S. Fisher, Jana Friedrich, Pere Masqué

Research outputs 2022 to 2026

Over six decades of research, two methods have been used to extract the natural radionuclides ²¹⁰Pb and ²¹⁰Po from seawater- the precipitation of iron hydroxide (Fe(OH)3) and coagulation of cobalt ammonium pyrrolidine dithiocarbamate (Co-APDC). Although the two methods had been intercompared for ²¹⁰Pb and shown to agree, they were never intercompared for ²¹⁰Po until Roca-Martí et al. (2021) , in which only unfiltered samples were used. Here we document that Fe(OH)3 may be less effective in extracting ²¹⁰Po from a seawater sample than Co-APDC. We hypothesize that cycling of ²¹⁰Po through the marine food …

Linking Local Ecological Knowledge And Management Perspectives On Oyster Predation In Mississippi And Alabama, Cynthia Lupton, Eric Sparks, Mark Woodrey, James M. Drymon, Nigel Temple, Steven Scyphers

Research Data

Eastern oysters (Crassostrea virginica) provide critical ecosystem services, yet populations along the northern Gulf Coast are declining due to environmental stressors, such as water quality issues and predation. To evaluate how threats to oysters are perceived across stakeholder groups, we surveyed oyster Farmers and Resource professionals in Mississippi and Alabama about predator impacts, seasonal patterns, and mitigation strategies. Survey responses (n = 21) were analyzed using descriptive statistics, Fisher’s Exact tests, Mann–Whitney U tests, and t-tests. Farmers and Resource professionals identified multiple predators as important sources of mortality, but their relative rankings differed across groups. Resource professionals consistently viewed southern …

Characterization And Advancement Of Molluscan Venom Gland Cell Model Systems, James V. Parziale

Dissertations, Theses, and Capstone Projects

Venomous mollusks, including cone snails and coleoid cephalopods, produce rich repertoires of bioactive peptides with profound effects on cellular physiology, yet there are few tractable experimental systems that exist to study their development, maintenance, and venom secretion. Although therapeutics such as the cone snail peptide Ziconotide demonstrate the biomedical potential of molluscan venoms, progress in understanding how venom glands form, function, and evolve has been hindered by the lack of reliable husbandry and the complete absence of in vitro cell models. Modern comparative genomics has revealed widespread convergent evolution across venomous lineages, but molluscan datasets remain underrepresented, limiting insights into …
