Interactive Effects Of Climate Change‐Induced Range Shifts And Wind Energy Development On Future Economic Conditions Of The Atlantic Surfclam Fishery, Stephanie Stromp, Andrew M. Scheld, John M. Klinck, Daphne M. Munroe, Eric N. Powell, Roger Mann, Sarah Borsetti, Eileen E. Hofmann

Faculty Publications

Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of the Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica. Fishers presently are prohibited from landing both Atlantic surfclams and ocean quahogs in the same catch, thus limiting fishing to locations where the target species can be sorted on deck. Wind energy development on and around the fishing grounds will further restrict the fishery. A spatially explicit model of the Atlantic surfclam fishery (Spatially Explicit Fishery Economics Simulator) has the ability to simulate the consequences of fishery displacement …

Dairy & Development: An Investigation Into The Economic And Sociopolitical Dynamics Of Yak Cheesemaking In Nepal, Audrey Peiker

Independent Study Project (ISP) Collection

Cheesemaking in Nepal is full of love, passion, and creativity. What began as a Swiss development project in the 1950s has now grown into a full-fledged industry, providing jobs, creative outlets, and cultural expression for many. Nepal’s Dairy Development Corporation owns several factories throughout the country, setting the tone for the industry by establishing the standard price for milk and process for cheesemaking. From there, privately held factories innovate and compete, bringing new products to the market and increasing wages, but also struggle with consistency and reliability. Now, Nepal’s cheesemaking market is at a turning point—much of the herding population …

Status Of Pangolins: A Case Study On "The Most Trafficked Mammal In The World" In Central-South Of Nepal, Tsogyal Wangmo Lama

Independent Study Project (ISP) Collection

Pangolins are subject to constant trafficking in Asia and increasingly in Africa for their meat and scales. Very little research is done on this species due to its nocturnal, burrowing, and elusive nature. The larger the size of an animal is, the better it is known to the people and vice versa. Hence all these eight species of pangolins despite being under the International Union for Conservation of Nature (IUCN) red list with the four Asian species declared endangered or critically endangered, are still illegally abused and used for ulterior motives due to a lack of awareness among the general …

Locomotor Biomechanics In Stream Gobies, Rhinogobius Sp.: Functional Performance Of Waterfall-Climbing Behavior, Ernest Murphy

Undergraduate Theses and Capstone Projects

Gobiidae is the taxonomic classification of a large fish family comprising over 2,000 species. A few goby species have the unique ability of scaling waterfalls using pelvic fins that are fused into a suction disc (pelvic sucker) located on the ventral side of the body, aiding them in upstream migration to freshwater feeding and reproduction locations. This study aimed to investigate the locomotor biomechanics of Rhinogobius goby fish due to the lack of literature in the area, and to better understand solutions this particular gobiid species exhibits while facing physical challenges. In particular, climbing performance variables (pressure differential, force, endurance, …

Genomic Analysis Of Exophiala Sp. Etnp2018, A Marine Fungal Strain Isolated From An Oxygen Minimum Zone, Margaret Kelly Bernish

Theses and Dissertations

Microbial metabolic activity is central to biogeochemical cycling in virtually all ecosystems. Fungi are important parts of microbial communities, serving as decomposers, parasites, and symbionts. Most of our understanding of fungal ecology is derived from the study of isolated, cultured terrestrial fungi. However, the marine environment includes thousands of divergent, uncultured fungi. A number of these species, which include saprobes, parasites, and endophytes, can survive and sporulate in a wide range of salinities. Other such species face the additional challenge of limited nutrient accessibility. The genus Exophiala includes agents of mycoses in both humans and in marine animals. This research …

Recombinant Dna Vaccine Design As A Potential Strategy Against Bovine Foot And Mouth Disease Virus (Fmdv), Taylor Haynie

LSU Master's Theses

Foot-and-mouth disease virus (FMDV) is the causative agent for foot-and-mouth disease (FMD) that infects primarily cloven-hoofed animals, the majority of which are domesticated cattle and other important livestock. FMD is highly transmissible and found in all secretions and excretions of infected animals. North America, Europe, and Australia have successfully eradicated the virus with the help of a well-defined fiscal infrastructure and access to successful control measures. Less developed regions, including many Asian and African countries, have maintained an endemic status for decades. African territories are of particular concern because of the indigenous African Buffalo population that serves as an important …

Diverse Portfolios: Investing In Tributaries For Restoration Of Large River Fishes In The Anthropocene, Kristen L. Bouska, Brian D. Healy, Michael J. Moore, Corey G. Dunn, Jonathan J. Spurgeon, Craig P. Paukert

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Rehabilitation of large Anthropocene rivers requires engagement of diverse stakeholders across a broad range of sociopolitical boundaries. Competing objectives often constrain options for ecological restoration of large rivers whereas fewer competing objectives may exist in a subset of tributaries. Further, tributaries contribute toward building a “portfolio” of river ecosystem assets through physical and biological processes that may present opportunities to enhance the resilience of large river fishes. Our goal is to review roles of tributaries in enhancing mainstem large river fish populations. We present case histories from two greatly altered and distinct large-river tributary systems that highlight how tributaries contribute …

These included the temperature–humidity index (THI), the adjusted THI (THI_adj), the heat load index (HLI), and THI_PST using pen surface temperature instead of air temperature. Respiration rates (RR), tympanic temperatures (TT), and panting scores (PS) were also collected in each year and from each location. During 2007, mean values of soil temperature, PST, outgoing shortwave radiation, and TT were greater than in 2008 …

Coastal Cities In The Southern Us Floodplains: An Evaluation Of Environmental Equity Of Flood Hazards And Social Vulnerabilities, Lubana Tasnim Mazumder

USF Tampa Graduate Theses and Dissertations

Floods are recognized as one of the most common and widespread natural hazards in the United States (US). They are responsible for uncompensated losses and damages. Furthermore, evidence suggests flooding inflicts more harm among socially vulnerable groups, incapable of withstanding hazard events, raising environmental equity (EE) and justice (EJ) concerns. Regrettably, with continuing climate change and urbanization, flooding will not subside in the future; instead, the flooding frequency and intensity will increase in many parts of the US, and the trend of disproportionate impacts will continue to rise.

Since Hurricane Katrina, a considerable amount of research has been conducted on …
