Eavesdropping On Animals: Can Bioacoustics Help Save Species?, Zoe Grueskin
Eavesdropping On Animals: Can Bioacoustics Help Save Species?, Zoe Grueskin
Capstones
Around the world, scientists are using sound to study the natural world in a growing field called bioacoustics. Researchers are eavesdropping on frogs and fish, elephants and earthworms, and many hope what they hear can inform and inspire conservation action around the world. From the field’s auspicious beginning with accidentally-recorded whales, to researchers today listening to locations as diverse as the Arctic seafloor and India’s Western Ghats mountain range, this capstone project explores the potential — and limitations — of conservation bioacoustics. Read the story, see photos and listen to audio pieces featuring three bioacousticians and their field recordings here: …
Using Reflex Actions To Predict Delayed Post-Harvest Mortality Of American Lobster (Homarus Americanus) In Maine’S Lobster Supply Chain, Cassandra Leeman
Using Reflex Actions To Predict Delayed Post-Harvest Mortality Of American Lobster (Homarus Americanus) In Maine’S Lobster Supply Chain, Cassandra Leeman
Electronic Theses and Dissertations
In live seafood industries, maintaining product quality and survivorship are critical aspects of the supply chain infrastructure. Post-harvest mortality in the American lobster (Homarus americanus) fishery can result in a significant loss in revenue for the largest single species fishery in North America. In Maine, the wholesale lobster distribution supply chain directly and indirectly supports state and local economies, providing almost $1 billion in revenue and dominates the fishery, producing 82% of the total lobster landings in the USA (Donihue, 2018; NOAA, 2021). However, at least 2% of the lobster landed in Maine die before they reach consumers, representing an …

Crustacean Assemblage Structure Over The Charlie-Gibbs Fracture Zone Of The Mid-Atlantic Ridge Collected During The 2009 Henry B. Bigelow Expedition, Kathryn Medina
All HCAS Student Capstones, Theses, and Dissertations
The Charlie Gibbs Fracture Zone (CGFZ) consists of two nearly parallel fracture transform faults that intersect the Mid-Atlantic Ridge (MAR) axis. This area has high primary productivity and biomass levels due to the topography and water. A predominant hydrographic feature of the MAR is the Sub-Polar Front (SPF) which runs along the southern edge of the CGFZ and is known as a biogeographical boundary for multiple species. As part of The Census of Marine Life project Patterns and Processes of the Ecosystem of the northern Mid-Atlantic (MAR-ECO), this study analyzed the abundance and distribution patterns of the CGFZ crustacean community …

Internal Vertebral Morphology Of Bony Fishes Matches The Mechanical Demands Of Different Environments, Dana Baxter, Karly E. Cohen, Cassandra M. Donatelli, Eric D. Tytell
Engineering Faculty Articles and Research
Fishes have repeatedly evolved characteristic body shapes depending on how close they live to the substrate. Pelagic fishes live in open water and typically have narrow, streamlined body shapes; benthic and demersal fishes live close to the substrate; and demersal fishes often have deeper bodies. These shape differences are often associated with behavioral differences: pelagic fishes swim nearly constantly, demersal fishes tend to maneuver near the substrate, and benthic fishes often lie in wait on the substrate. We hypothesized that these morphological and behavioral differences would be reflected in the mechanical properties of the body, and specifically in vertebral column …

Smart Drumlines Ineffective In Catching White Sharks In The High Energy Capes Region Of Western Australia: Acoustic Detections Confirm That Sharks Are Not Always Amenable To Capture, Stephen M. Taylor, Jason How, Michael J. Travers, Stephen J. Newman, Silas Mountford, Daniela Waltrick, Christopher E. Dowling, Ainslie M. Denham, Daniel J. Gaughan
Fisheries Research Articles
The management of human-shark interactions can benefit from the implementation of effective shark hazard mitigation measures. A Shark-Management-Alert-in-Real-Time (SMART) drumline trial in the Capes region of Western Australia was instigated after several serious incidents involving surfers and white sharks (Carcharodon carcharias). The project aimed to determine whether white sharks (target species), which were relocated after capture, remained offshore using satellite and acoustic tagging. Over a 27-month period, 352 fish were caught, 55% of which comprised tiger sharks (Galeocerdo cuvier). Ninety-one percent of animals were released alive in good condition. Only two white sharks were caught; both were relocated ≥ 1 …
Ecological Modeling In The Oceanic Zone: A Gulf Of Mexico Case Study, Matthew Woodstock
Ecological Modeling In The Oceanic Zone: A Gulf Of Mexico Case Study, Matthew Woodstock
FIU Electronic Theses and Dissertations
Ecological modeling is a popular tool to assess the functionality of marine ecosystems and quantify an ecosystem’s response to anthropogenic stressors (e.g., fishing, oil spills, climate change). However, much of the global modeling effort has been focused on coastal regions that are generally more data-rich than the area seaward of the continental shelf (i.e., oceanic zone). A concerted effort has been placed on collecting holistic, ecosystem-scale data in the oceanic, northeast Gulf of Mexico since the 2010 Deepwater Horizon oil spill (DWHOS), particularly in the deep-pelagic zone (water column deeper than 200m depth), which has notably experienced declines in several …

Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack
Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack
Faculty Publications
Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …
Impacts On Fast-Start Performance: How Do Group Size And Habitat Degradation Alter The Escape Behavior Of A Schooling Coral Reef Fish?, Monica D. Bacchus
Impacts On Fast-Start Performance: How Do Group Size And Habitat Degradation Alter The Escape Behavior Of A Schooling Coral Reef Fish?, Monica D. Bacchus
All HCAS Student Capstones, Theses, and Dissertations
Escaping predation is essential for species survival, but prey must effectively match their response to the perceived threat imposed by a predator. Fish evaluate their surroundings using several sensory stimuli, including olfactory, visual, auditory, and mechanical cues. A range of taxa use the fast-start response to evade predators, including fishes, sharks, and larval amphibians. While the fast-start response (rapid bursts of swimming) is extensively studied in solitary fishes, the factors that mediate the collective escape response in schools of fish have historically been investigated far less. To address this knowledge gap, the collective escape behavior and individual escape performance of …

Abundance, Site-Fidelity, And Association Patterns Of Coastal Bottlenose Dolphins (Tursiops Truncatus) Off Southeast Florida, Graysen D. Boehning
All HCAS Student Capstones, Theses, and Dissertations
The coastal bottlenose dolphin is well studied throughout its natural range, however, most of the study areas comprised wide, well-protected habitats such as bays and estuaries, and not narrow coastal sandbanks. This study identifies a residential group of coastal bottlenose dolphins utilizing the narrow sandbanks within the Northwestern Atlantic waters off the coast of Palm Beach County, Florida, USA. From 2014-2020, 313 boat surveys were conducted, and 585 individual dolphins were identified using photo-ID. Twenty-four animals were determined to be full-time and 66 animals were determined to be part-time residents. Full-time and part-time residents associated in three social tribes, with …

Fisheries Genomics Of Snapper (Chrysophrys Auratus) Along The West Australian Coast, Andrea Bertram, David Fairclough, Jonathan Sandoval-Castillo, Chris Brauer, Anthony Fowler, Maren Wellenreuther, Luciano B. Beheregaray
Fisheries Research Articles
The efficacy of fisheries management strategies depends on stock assessment and management actions being carried out at appropriate spatial scales. This requires understanding of spatial and temporal population structure and connectivity, which is challenging in weakly structured and highly connected marine populations. We carried out a population genomics study of the heavily exploited snapper (Chrysophrys auratus) along ~2600 km of the Australian coastline, with a focus on Western Australia (WA). We used 10,903 filtered SNPs in 341 individuals from eight sampling locations to characterize population structure and connectivity in snapper across WA and to assess if current spatial …

Validation Of Pilot Protocol: Damage Scoring Of Puget Sound Mollusk Shells, Lauren Doffing
Environmental Science Undergraduate Theses
The Marine Sediment Monitoring Team at the Washington State Department of Ecology observed damage to mollusk shells while studying the benthic communities of Puget Sound. A pilot protocol was written to allow researchers to quantify the damage. Two researchers independently followed the protocol, including reference photos, for a set of samples collected in 2019 from an urban bay, East Possession Sound. Two scores were given to each specimen: highest-level damage and extent of highest-level damage. An additional score was given to bivalve species: rust/stain. The sets of scores were compared to determine if the protocol yielded similar values between the …
A Review Of Current Sea Cucumber And Apostichopus Californicus Knowledge And A Proposal For Future Research And Fishery Management, Lily Haug
University Honors Theses
The sea cucumber species Apostichopus californicus is fished in the Pacific Northwest region of North America and has the potential to be an economically beneficial fisheries species. An understanding of their population levels must be present to sustainably regulate their harvest. Current fisheries in North America vary in their methodology and level of regulation. The current regulations are presented and their strengths and shortfalls are described. This review gathers research done on tropical sea cucumber species and presents that knowledge alongside that regarding Apostichopus californicus to suggest future research and fishery management strategies. A. californicus takes four years to sexually …
Climate-Driven Stock Shifts And Expansions In The U.S. Northeast Shelf: Identifying Challenges, Opportunities, And Barriers Through Fishermen And Manager Perspectives, Sophie A. Swetz
All Theses And Dissertations
Climate-driven warming in the U.S. Northeast Shelf (NES) has led to changes in the spatial distributions of many marine resources. Shifts and expansions of commercially important fish stocks pose major challenges to fishermen and fisheries managers in this region. American lobster (Homarus americanus) in the Gulf of Maine (GOM) is one of these impacted stocks and is projected to continue its shift towards more northern and offshore areas. Continued ocean warming could potentially reduce the GOM lobster stock by up to 60% over the next several decades. Given Maine’s reliance on its lobster fishery—which contributes over 80% of …
Possible Surf And Turf Mutualism: The Potential Of Yeast Grown From Maine Wood As Feed For Atlantic Salmon, Gina Scott
Possible Surf And Turf Mutualism: The Potential Of Yeast Grown From Maine Wood As Feed For Atlantic Salmon, Gina Scott
All Theses And Dissertations
With fed aquaculture expanding, challenges are being faced with increasing demands for protein for feed. Fishmeal as a protein is at high cost and low supply, and meals from terrestrial agriculture can impact fish health; both also generate environmental challenges. One potential alternative protein is yeast, which can be grown using waste softwood. Simultaneously, Maine forestry has lost buyers of waste wood with several paper mill closures. If yeast is produced as an alternative protein for fish feed using this wood, both Maine Atlantic salmon farming, Maine’s most valuable form of aquaculture, and Maine forestry could benefit. Environmental impact and …

Accumulation Of Persistent Organic Pollutants In Marine Mammals: A Case Study On Cetaceans, Pinnipeds, And Sirenians, Alydia Moorhead
Accumulation Of Persistent Organic Pollutants In Marine Mammals: A Case Study On Cetaceans, Pinnipeds, And Sirenians, Alydia Moorhead
All HCAS Student Capstones, Theses, and Dissertations
Persistent organic pollutants (POPs) are lipophilic semi-volatile organic chemicals that present a range of challenges to marine biota, specifically marine mammals that often occupy a high trophic position in the food web. POPs have become a global problem since they have been shown to cause immunologic, teratogenic, carcinogenic, neurological, and reproductive complications in living organisms due to their resistance to biodegradation and their lipophilic nature. Marine mammals can accumulate these toxic substances through direct ingestion, trophic transfer, adsorption, and maternal offloading. They are susceptible to both bioaccumulation and biomagnification of POPs. Accumulation of POPs is affected by many variables, including …
