Novel Microbiological Medium Developed For The Isolation Of Bacteria Associated With Estuarine Anemones, 2024 California State Polytechnic University, Humboldt
Novel Microbiological Medium Developed For The Isolation Of Bacteria Associated With Estuarine Anemones, Parker K. Lund
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, 2024 College of Coastal Georgia
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 …

Investigating Optimal Laboratory Growth Conditions Of Gracilibacillus Halotolerans In Media Supplemented With Salt, Isaac Young
Annual Research Symposium
As interest continues to grow in the field of persister cells and their morphology, there arises an ever-evolving desire to further understand specific strains of bacteria that exemplify the qualities of seemingly anomalous survival regardless of anti-bacterial treatment. In the case of the Gracilibacillus halotolerans, a halotolerant extremophile extracted from the Great Salt Lake with known persistent characteristics, uncovering its optimal growth conditions was essential for future investigations. Identifying the optimal salinity for the growth of G. halotolerans will allow us to standardize our growth methods, uncover several mechanisms of saline tolerance, and add to future investigations of persistence with …

Salmonella is a genus of Gram-negative bacteria that is responsible for numerous food poisoning outbreaks worldwide. With 93.8 million food-borne illnesses and 155,000 fatalities annually, it has emerged as a significant global public health issue. There are currently more than 2,500 distinct Salmonella serotypes, and more than half of them are associated with Salmonella enterica. An increasing global public health concern for humans and animals is antimicrobial resistance by Salmonella species worldwide. Salmonella infections can be lethal; conditioned with an increased prevalence of multi-drug resistant (MDR) strains in the future. The emergence of MDR Salmonella serotypes is considerably …
Trends In Catch Rates Of Sawfish On The Australian North West Shelf, 2024 Department of Primary Industries and Regional Development, Western Australia
Trends In Catch Rates Of Sawfish On The Australian North West Shelf, C. Wakefield, S. J. Newman, M. Braccini, A. Harry
Fisheries Journal Articles
Northwestern Australia is thought to have some of the world’s last remaining viable sawfish populations, although little quantitative data exists on their status or trends. This study examined 17 years of logbook bycatch records (n = 815) for green sawfish Pristis zijsron and narrow sawfish Anoxypristis cuspidata from a trawl fishery operating on the Australian North West Shelf. Incidental sawfish captures by the fishery are rare, occurring approximately once every 75 trawls (~199 trawl hours). To standardize catch rates and account for excess zeros in the data, we employed generalized additive models for location, scale, and shape (GAMLSSs) using a …

Animal Conservation In St. Louis, Kate O'Sullivan
Undergraduate Research Symposium
St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …
A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, 2024 Purdue University
A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan
The Journal of Purdue Undergraduate Research
Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

Managing Inter-Organizational Trust And Risk Perceptions In Transboundary Fisheries Governance Networks, 2024 McGill University
Managing Inter-Organizational Trust And Risk Perceptions In Transboundary Fisheries Governance Networks, Evelyn Roozee, Dongkyu Kim, Antonia Sohns, Jasper R. De Vries, Owen Temby, Gordon M. Hickey
School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations
Transboundary fishery management represents a significant governance challenge that requires ongoing inter-organizational communication, collaboration, and collective action to ensure sustainability. Previous research suggests that different dimensions of perceived risk, trust, and control interact in complex ways to affect inter-organizational collaborative performance, providing an administrative ‘architecture’ that enables partners to share resources, engage in teamwork, resolve conflict, and coordinate tasks and responsibilities while also allaying their concerns about the alliance. However, the extent to which different control mechanisms influence trust and mitigate the perceived risks of collaboration between the diverse organizations involved in transboundary fisheries management remains unclear. This paper presents …

Region-Specific Drivers Cause Low Organic Carbon Stocks And Sequestration Rates In The Saltmarsh Soils Of Southern Scandinavia, Carmen Leiva-Dueñas, Anna E. L. Graversen, Gary T. Banta, Jeppe N. Hansen, Marie L. K. Schrøter, Pere Masqué, Marianne Holmer, Dorte Krause-Jensen
Research outputs 2022 to 2026
Saltmarshes are known for their ability to act as effective sinks of organic carbon (OC) and their protection and restoration could potentially slow down the pace of global warming. However, regional estimates of saltmarsh OC storage are often missing, including for the Nordic region. To address this knowledge gap, we assessed OC storage and accumulation rates in 17 saltmarshes distributed along the Danish coasts and investigated the main drivers of soil OC storage. Danish saltmarshes store a median of 10 kg OC m−2 (interquartile range, IQR: 13.5–7.6) in the top meter and sequester 31.5 g OC m−2 yr−1 (IQR: 41.6–15.7). …
