Spora: A Journal of Biomathematics
This study examines the effects of environmental changes on fish populations in Norwalk Harbor, focusing on winter flounder (Pseudopleuronectes americanus), cunner (Tautogolabrus adspersus), northern pipefish (Syngnathus fuscus), and naked goby (Gobiosoma bosci) as examples of species responding to climate-related shifts. We analyze how water temperature, salinity, and dissolved oxygen correlate with fish abundance. To assess statistically significant differences in catch per unit effort (CPUE) across harbor regions, we applied the Kruskal-Wallis test followed by Dunn's post-hoc test. Seasonal variations in CPUE were examined by comparing monthly catch data for each species. K-means …

There is a worldwide shortage of hydrographic personnel (van Wegen, 2021, Hydro International 2008). Calls for action to address this issue include the IHO’s Hydrography at Sea opportunities, while intiatiative such as Seabed 2030 are bringing broader attention to the field and helping to catalyze new discussions and partnerships in hydrography (IHO, 2024). The global sea floor mapping community needs to develop a broader workforce pipeline. We would like to highlight the importance of providing time at sea and leadership opportunities in developing a robust workforce. We start with an overview of a selection of current exchange and training programs …

Journal of Ocean and Coastal Economics
A growing number of countries have announced net-zero and net-negative emissions targets, but only a few countries provide incentives for carbon dioxide removal (CDR). We derive estimates of countries' hypothetical demand for CDR in 2030 based on their emissions reduction targets under the Paris Agreement. The aggregated average global demand for CDR in the compliance year 2030 is 1064 MtCO2, 353 MtCO2, and 124 MtCO2 for the low, medium, and high-cost CDR scenarios, respectively. This demand comes exclusively from countries and regions with relatively high GDP per capita, relatively high abatement costs and a limited …

Climate change is increasing average temperatures and the frequency and intensity of thermal extremes in coastal marine environments. Organisms in coastal marine habitats are accustomed to environmental fluctuations and possess physiological plasticity that may be advantageous in response to increased occurrence of extremes. To examine whether such plasticity is locally adapted to environmental conditions, we investigated the relationship between genetic diversity and thermal tolerance plasticity in 11 populations of the direct-developing intertidal sea hare, Phyllaplysia taylori, on the western coast of the United States. Using whole-organism metrics of muscle function and metabolic rate and a ddRADseq genomic approach, we …

Consumption Habitats Of Male And Female Lionfish Regarding The Production Of Eggs, Zalyn Baker, Natalie Tipsword, Sam Fisher
Symposium of Student Scholars
The lionfish, scientifically known as Pterois, belongs to the Scorpaenidae family, which is native to the Indo-Pacific Ocean, but has become an invasive species in the Caribbean Sea. First observed in Belize in 2008, lionfish have since become established in the Belize Barrier Reefs. Known for their ability to consume a wide range of species, lionfish compete with native fish for food resources. This invasive species poses a significant threat to the ecosystem due to their venomous spines, aggressive predatory behavior, lack of predators, and high reproductive rate, with lifespans extending up to 30 years. Our study aimed to investigate …

Native fishes face imperilment due to habitat loss and fragmentation, megadrought, invasive species, and synergies amongst threats. These threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by a suite of nonnative fishes. Water level in Lake Powell has declined precipitously due to water overallocation and megadrought, increasing the risk of nonnative fish entrainment through the dam, as the penstocks draw water from the epilimnion. Our goal was to characterize the distribution and abundance of nonnative fishes in the vicinity of GCD and identify environmental conditions that may increase entrainment. …

In a context of rapid global change, understanding whether and how adaptation to climate change can be considered successful has become an important research gap within the climate change adaptation literature. Although definitions of adaptation success have been formulated, it remains unclear how they can be operationalized and tested empirically. To address this gap, we operationalized one of the most prominent definitions of successful adaptation within the academic literature, which describes success as adaptations that support reductions in risk and vulnerability without compromising sustainability. Specifically, drawing on data collected from 209 coral reef tourism operators across 28 locations and eight …

Have you ever played with sand at the beach? Did you know you were also playing with thousands of tiny animals? The sand in the ocean is home to many small creatures called meiofauna, but you can only see them under a magnifying glass or microscope. Meiofauna are so tiny that sand grains seem like boulders to them. Meiofauna are too small to move these boulders, so they wriggle through spaces between them. Living in such tight spaces has led them to evolve long, skinny body shapes like worms. They also have special body parts to grip sand grains and …

Understanding the fine-scale behavioural and feeding ecology of marine megafauna is imperative for effective management of their habitat areas; however, obtaining the relevant data can be both costly and challenging. Here we integrate the use of small drones for dugong surveys with underwater benthic habitat assessment techniques at the local spatial scale (∼30 km2), to determine the drivers of dugong (Dugong dugon) distribution across three locations in the Pilbara, Western Australia. Paired assessment data was collected three times over two years. Benthic habitat (percent cover), seagrass nutritional quality and environmental parameters (temperature, water clarity, water current, water depth) were tested …

Under The Bay: Analysis Of Green Sea Turtle (Chelonia Mydas) Dive Behavior In The Urban San Diego Bay, Emily Carter
Theses
Sea turtles are air-breathing marine reptiles that spend their lives performing dives to travel, forage, and rest. Several dive types have been previously recorded for sea turtles, each type being associated with a different set of behaviors. U-dives, or Type 1 dives are widely characterized by extensive benthic periods preceded by and concluding with abrupt descent and ascent phases respectively (Minamikawa et al. 1997; Houghton et al. 2002; Seminoff et al. 2006). These dives are widely affiliated with turtle resting behavior though can be indicative of additional activities including benthic travel and foraging. Previous research of green turtle dive behavior …

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan
Theses
In the eastern North Pacific, the oxygen minimum zone naturally shoals seasonally and impacts demersal fish habitat along the continental margins and on offshore seamounts. This hypoxic layer has been shoaling in recent decades, likely affecting the habitat and distribution of commercially-important fish species such as rockfishes (genus Sebastes). Respirometry and shuttle box behavioral experiments were used to determine the hypoxia sensitivities of two rockfish species with contrasting movement patterns and habitat use: cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis). Although both species inhabit similar deep-water, rocky-reef habitat, they have different lifestyles, in which cowcod …

The conservation of freshwater turtle species depends on precise and effective monitoring techniques. Environmental DNA (eDNA) analysis is a potential method for identifying cryptic and elusive turtle species in aquatic ecosystems. eDNA analysis can help to identify key regions for conservation efforts and monitor changes in population levels over time. This study aims to evaluate the effectiveness of a rapid eDNA detection method for the yellow mud turtle (Kinosternon flavescens, an indicator species that is endangered in some states in the USA), which inhabits local oxbow lakes (e.g., resacas) in Cameron County, South Texas. A species-specific nested PCR …

Ghost Fishing Due To Derelict Crab Traps In Louisiana’S Barataria Basin, Emma C. Villemarette
LSU Master's Theses
Ghost fishing, the unintentional entrapment of sea life by derelict fishing gear, is an ecologic and socioeconomic concern in Louisiana's crabbing industry (blue crab, Callinectes sapidus). These ghost fishing traps cause unknown and unaccounted for mortality in blue crab and bycatch species. I aimed to track changes to derelict crab trap catch and trap deterioration over seasons and between habitats. I set and monitored 33 simulated derelict crab traps over 367 soak days in three varying habitats along Barataria Bay, Louisiana. Traps were checked once every two weeks and an additional daily check for five days per season. Blue …

Immunological, reproductive, and population endpoints were assessed in fish-eating birds during 2010–2019 in the Saginaw River and Bay and River Raisin Areas of Concern (AOCs) and Grand Traverse Bay, which are ecosystems historically contaminated with polychlorinated biphenyls, dibenzo-p-dioxins, and dibenzofurans. Reference sites were in the lower St. Marys River (herring gulls and Caspian terns), eastern Lake Superior (terns), and eastern Lake Huron (black-crowned night herons). Relative risk ratios for embryonic nonviability (from both infertility and mortality) in gull embryos were 2–3-fold higher than the reference site in both AOCs and Grand Traverse Bay. Twelve of 13 deformed embryos and chicks …

Honors Senior Capstones and Theses
Climate change is affecting our oceans negatively in many ways, such as rising temperatures and increased disease outbreaks. While there are many diseases that are affecting marine organisms, bacteria of the genus Vibrio are present globally and are known to favor warmer waters, which means increasing temperatures will cause an uptick in infections. One species, V. coralliilyticus, has been identified as a pathogen responsible for coral disease and death as well as mortality in rainbow trout, brine shrimp, and Pacific oyster larvae. A possible solution to the rising prevalence of disease is the use of probiotics. One such probiotic candidate …
