Anthropogenic activities are causing detrimental changes to coastal plants– namely seagrass, mangrove, and tidal marshes. Looking beyond recent times to past vegetation dynamics is critical to assess the response and resilience of an environment to change. Here, we develop a high-resolution multi-proxy approach, providing a new evidence base to decipher long-term change in coastal plant communities. Combining targeted environmental DNA analysis with chemical analysis of soils, we reconstructed 4,000 years of change at a temperate wetland on Torrens Island South Australia and identified an ecosystem shift that occurred ~ 1000 years ago. What was once a subtidal seagrass system shifted …

The State Of Knowledge Of Cca Diversity In The Caribbean Coral Reefs, Danielle Macias, Alain Duran, Fabio Nauer May 2024

The State Of Knowledge Of Cca Diversity In The Caribbean Coral Reefs, Danielle Macias, Alain Duran, Fabio Nauer

FIU Undergraduate Research Journal

Crustose coralline algae (CCA) are a diverse and ecologically important species found in most of the world’s oceans. The current lack of taxonomic knowledge and relative abundance compromises our ability to predict species diversity numbers and, thus, their ecological roles and impacts on coral reefs. To gather a better understanding of the state of knowledge of crustose coralline algae taxonomy in the Caribbean, 107 different research papers, and other primary and secondary literature were studied; any source with taxonomical information, species identification, or genetic markers for identification was recorded. All Genebank codes were collected and sorted by supposed species marker …

With Love, ; An Interdisciplinary And Intersectional Look At Why Creativity Is Essential, Theo Starr Gardner

Whittier Scholars Program

My Whittier Scholars Program self-designed major, Teaching Creativity, is a mixture of Art, Literature, and Education classes. My research and praxis classes have been focused on the ‘how?’s and 'why?’s of creativity, so it felt only right that my project should be a constructivist, generative project. The project I have been working on throughout my time at Whittier, and that has just fully come to fruition on April 11th, 2024, was a solo art gallery/open mic event entitled ‘With Love,’. With Love, was conceptually inspired by the research I’ve conducted on creativity and creative arts education over the past few …

The Influence Of A Ubiquitous Filter Feeder On Coastal Microbial Communities., Melissa Steinman, Moritz S. Schmid, Robert K. Cowen, Su Sponaugle, Kelly R. Sutherland, Anne W. Thompson

Student Research Symposium

Doliolids have a unique ability to impact the marine microbial community through bloom events and high filtration rates. Their predation on large eukaryotic microorganisms is established and evidence of predation on smaller prokaryotic microorganisms is beginning to emerge. We studied the retention of both eukaryotic and prokaryotic microbial taxa by wild-caught doliolids in the northern California Current system. We use qPCR to quantify the impact of doliolids on three important and globally abundant taxa: Synechococcus, SAR11 and diatoms. Doliolids were collected during bloom events identified at three different shelf locations with variable upwelling intensities. We discovered that in addition …


Variability Of Grazing By Appendicularians On Prochlorococcus, Carey Sweeney May 2024

Variability Of Grazing By Appendicularians On Prochlorococcus, Carey Sweeney

Student Research Symposium

The marine picocyanobacterium, Prochlorococcus is the most abundant photosynthetic cell on Earth. These cells are critical to global primary productivity and are critical to biogeochemical cycles of the open ocean. While abiotic environmental factors that influence Prochlorococcus are relatively well-understood, biotic controls, especially predation, are not well-studied. Appendicularians are ubiquitous invertebrate grazers that feed on microbes including Prochlorococcus in the open ocean. However, the details of this feeding interaction have not been characterized. In a laboratory study, I showed that prey retention of Prochlorococcus increases as the life stage of the appendicularians advances and increases with increasing concentration of prey. …

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

Numerous genomic methods developed over the past two decades have enabled the discovery and extraction of orthologous loci to help resolve phylogenetic relationships across various taxa and scales. Genome skimming (or low-coverage genome sequencing) is a promising method to not only extract high-copy loci but also 100s to 1000s of phylogenetically informative nuclear loci (e.g., ultraconserved elements [UCEs] and exons) from contemporary and museum samples. The subphylum Anthozoa, including important ecosystem engineers (e.g., stony corals, black corals, anemones, and octocorals) in the marine environment, is in critical need of phylogenetic resolution and thus might benefit from a genome-skimming approach. We …


West Coast Rock Lobster Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia May 2024

West Coast Rock Lobster Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia

Fisheries management papers

Harvest strategies for Western Australia’s (WA) aquatic resources are formal documents developed by the Department of Primary Industries and Regional Development (DPIRD, the Department) to support decision-making processes that ensure the outcomes are consistent with the principles of Ecologically Sustainable Development (ESD; Fletcher 2002a) and Ecosystem Based Fisheries Management (EBFM; Fletcher et al. 2012). Harvest strategies are a key component of all contemporary fishery management systems and a requirement for certification under the Marine Stewardship Council (MSC). The objectives of ESD are reflected in the objectives of the Fish Resources Management Act 1994 (FRMA) and the Aquatic Resources Management Act …


An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny Apr 2024

An Examination Of The Eastern Nebraska And Western Iowa Flash Flood Event Of 6-7 August 1999, Catherine M. Zapotocny

NOAA Technical Reports and Related Materials

Flash flooding occurs each summer in eastern Nebraska and western Iowa. While 10-inch rains are extraordinary, it is not uncommon to have at least one excessive rain event during the annual convective season. A significant flash flood occurred in east central Nebraska and western Iowa the night of August 6, 1999 into the morning of August 7, 1999. Antecedent hydrologic conditions limited the loss of life, however considerable property damage resulted as the heavy rain fell over the urbanized areas in eastern Nebraska and western Iowa.

Several flash flood ingredients came together over the area. These meteorological factors are typical …


Trophic Ecology Of Black Swallowers (Scombriformes: Chiasmodontidae: Chiasmodon) In The Deep-Pelagic Gulf Of Mexico, Travis J. Kirk Apr 2024

Trophic Ecology Of Black Swallowers (Scombriformes: Chiasmodontidae: Chiasmodon) In The Deep-Pelagic Gulf Of Mexico, Travis J. Kirk

All HCAS Student Capstones, Theses, and Dissertations

The ecology of deep-pelagic predatory fishes remains poorly understood despite their importance as ecosystem regulators and energy transfer vectors. This study investigated the trophic ecology of three species of the predatory fish genus Chiasmodon (“black swallowers”) in the Gulf of Mexico, a region that serves as an analog for the global low-latitude deep pelagial, the world’s largest cumulative ecosystem. Foraging habits (e.g., selectivity, chronology, daily ration) of an “advanced” evolutionary fish in a system that is otherwise dominated by basal fish taxa, were quantitatively estimated via high-resolution stomach content analysis. A quantitative dataset of both predator and prey abundance, the …


Rescape: Transforming Coral-Reefscape Images For Quantitative Analysis, Zachary Ferris, Eraldo Ribeiro, Tomofumi Nagata, Robert Van Woesik Apr 2024

Rescape: Transforming Coral-Reefscape Images For Quantitative Analysis, Zachary Ferris, Eraldo Ribeiro, Tomofumi Nagata, Robert Van Woesik

Ocean Engineering and Marine Sciences Faculty Publications

Ever since the first image of a coral reef was captured in 1885, people worldwide have been accumulating images of coral reefscapes that document the historic conditions of reefs. However, these innumerable reefscape images suffer from perspective distortion, which reduces the apparent size of distant taxa, rendering the images unusable for quantitative analysis of reef conditions. Here we solve this century-long distortion problem by developing a novel computer-vision algorithm, ReScape, which removes the perspective distortion from reefscape images by transforming them into top-down views, making them usable for quantitative analysis of reef conditions. In doing so, we demonstrate the …


Changes In Reef Tourism’S Adaptive Capacity After Severe Climate Disturbances, Henry Bartelet, Michele Barnes, Lalu Bakti, Graeme S. Cumming Apr 2024

Changes In Reef Tourism’S Adaptive Capacity After Severe Climate Disturbances, Henry Bartelet, Michele Barnes, Lalu Bakti, Graeme S. Cumming

Quantitative Methods and Information Technology Faculty Publications

Knowledge about adaptive capacity and its determinants has increased significantly over the last decade. However, most research on adaptive capacity has been static, not considering how adaptive capacity might change over time, particularly after severe disturbances. We studied the adaptive capacity dynamics of Asian-Pacific reef tourism operators affected by coral bleaching and tropical cyclones compared with a control group with non-affected operators. We found that impacts from tropical cyclones were associated with frequent changes in adaptive capacity. Notably, we found a reduction in tangible attributes (assets and flexibility) of adaptive capacity, whereas intangible attributes (agency and social organization) increased. Our …


Addition And Subtraction: Coral Reproduction And Disease In A Changing Ocean, Ashley Rossin Apr 2024

Addition And Subtraction: Coral Reproduction And Disease In A Changing Ocean, Ashley Rossin

LSU Doctoral Dissertations

Marine diseases are changing the landscapes of coral reefs particularly throughout the Western Atlantic. Stony coral tissue loss disease (SCTLD) swept through this region impacting at least 22 stony coral species. White plague (WP) is a more ephemeral disease, but still has a significant impact on coral reef health and perseverance, especially under a changing ocean. While these impacts are seen on the reef-scale, we can zoom into the tissue-level to identify disease markers for both diseases and identify their differences. This has ramifications for disease intervention, as well as mitigation strategies. Despite continuous disease outbreaks, healthy corals persist and …

Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand Apr 2024

Distribution Of Shell-Boring Polychaetes At Shellfish Aquaculture Sites Along The Northeast Coast Of The Us, Samantha Silverbrand

Honors College

Coastal shellfish aquaculture has expanded substantially in recent years in Maine and New England as traditional wild fishery stocks have declined. As shellfish aquaculture has expanded, producers have become more concerned about marine worm pests (i.e., polychaetes) that infest cultured bivalves. In particular, worms from the genus Polydora (also known as “polydorids”) burrow into oyster and scallop shells where they feed and deposit mud. Bivalves cover over the muddy burrows creating blisters that can decrease their market value and hinder growth. Farmers and researchers have identified methods to control infestations of P. websteri, one common species of shell-boring worm. However, …


The Effect Of Submarine Groundwater Discharge On Greenhouse Gas Production On A Coral Reef In Maunalua Bay, Hi, Kylie Nichols Mar 2024

Seaver College Research And Scholarly Achievement Symposium

THE EFFECT OF SUBMARINE GROUNDWATER DISCHARGE ON GREENHOUSE GAS EMISSIONS IN MAUNALUA BAY, HI

Authors: Kylie Nichols, Dr. Carmella Vizza, Dr. Florybeth La Valle

Abstract: In the urban coastal environments of Honolulu, Hawai’i, water high in inorganic nutrients such as nitrates, phosphates, and ammonia, often becomes further enriched by human activity. This water seeps into the ocean by mode of submarine groundwater discharge (SGD).

We hypothesize that SGD influences greenhouse gas (GHG) production in coastal systems at a measurable rate and is overlooked as a significant source of methane emissions. Marshes and wetlands are the largest contributors to methane production …


Novel Microbiological Medium Developed For The Isolation Of Bacteria Associated With Estuarine Anemones, Parker K. Lund, Catalina Cuellar-Gempeler Mar 2024

Novel Microbiological Medium Developed For The Isolation Of Bacteria Associated With Estuarine Anemones, Parker K. Lund, Catalina Cuellar-Gempeler

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

Out of the nearly one trillion species of microbiota estimated to inhabit Earth only ten thousand have been cultured in the laboratory. Culturing continues to play a vital role in determining the physiology and ecologic function of individual bacteria in microbial communities and for microbes associated with host organisms one of the major challenges is developing microbiological media that mimics the bacteria’s natural environment enough to promote growth. Here, we target bacteria associated with the estuary anemones Diadumene lineata and Metridium senile by developing a novel medium that uses anemone tissue as the sole source of nutrients. We further measured …


Ecological And Educational Impacts Of A Living Shoreline On St. Simons Island, Georgia, Usa, C. Tate Holbrook, Cameron Atkinson, Jordan Fountain, Stephanie Knox, Jan Mackinnon Mar 2024

Ecological And Educational Impacts Of A Living Shoreline On St. Simons Island, Georgia, Usa, C. Tate Holbrook, Cameron Atkinson, Jordan Fountain, Stephanie Knox, Jan Mackinnon

Georgia Journal of Science

Living shorelines encompass a range of nature-based alternatives to traditional coastal armoring structures. In addition to shoreline stabilization and protection, living shorelines are intended to meet conservation goals such as restoring habitat, delivering ecosystem services, and promoting ecological resilience to climate change. While early results have been promising, further monitoring is needed to better understand and evaluate the performance of living shorelines across a range of designs and environmental contexts, thereby informing coastal management. Nature-based shoreline protection is relatively new in Georgia, USA, where in 2015 the state’s fourth living shoreline was constructed of oyster shell and native plants on …

Application Of The Analytic Hierarchy Process And Geographic Information System In Selecting Sites For A Seafood Market Study, Shielameh Peralta-Milan, Osamu Baba, Severino Iii Salmo

The Philippine Agricultural Scientist

Study site selection is essential for the success of many fisheries-related programs. A thorough site selection could provide transparency in the decision-making process and optimize resources. In this research, the analytic hierarchy process (AHP) approach was used to select sites for a market study of reef-associated seafood in Alaminos City, Northwestern Philippines. Out of the 10 coastal barangays, four (Lucap, Sabangan, Telbang, and Victoria) were initially chosen, and the difference between these sites and the priority sites generated from AHP was examined. Five decision criteria and 10 alternatives (coastal barangays) were analyzed to calculate priority weights using pairwise comparisons. The …

Research outputs 2022 to 2026

Assessing historical environmental conditions linked to habitat colonization is important for understanding long-term resilience and improving conservation and restoration efforts. Such information is lacking for the seagrass Zostera marina, an important foundation species across cold-temperate coastal areas of the Northern Hemisphere. Here, we reconstructed environmental conditions during the last 14,000 years from sediment cores in two eelgrass (Z. marina) meadows along the Swedish west coast, with the main aims to identify the time frame of seagrass colonization and describe subsequent biogeochemical changes following establishment. Based on vegetation proxies (lipid biomarkers), eelgrass colonization occurred about 2,000 years ago after geomorphological changes …
