Perils Of The Fungal Kingdom: Mycotoxins In Food And Feed, Adrianna Isobel Pribil 2018 Louisiana State University

Perils Of The Fungal Kingdom: Mycotoxins In Food And Feed, Adrianna Isobel Pribil

LSU Master's Theses

Humans and fungi have a complex relationship, especially in regards to the many fungal secondary metabolites that can be produced. When secondary metabolites are toxic to animals and humans they are defined as mycotoxins. Fungi can grow on crops pre-harvest and post-harvest, and have the potential to produce mycotoxins which occur regularly in animal feed and food for human consumption. In high doses, mycotoxins cause variety of problems that result in economic losses and extreme health issues. However, multiple mycotoxins will co-occur in nature and commonly occur in low doses. Thus chronic low daily doses of multiple mycotoxins overtime may ...


Exploring The Amphibian Exposome In An Agricultural Landscape Using Telemetry And Passive Sampling, Jennifer E. Swanson, Erin Muths, Clay L. Pierce, Stephen J. Dinsmore, Mark W. Vandever, Michelle L. Hladik, Kelly L. Smalling 2018 Iowa State University

Exploring The Amphibian Exposome In An Agricultural Landscape Using Telemetry And Passive Sampling, Jennifer E. Swanson, Erin Muths, Clay L. Pierce, Stephen J. Dinsmore, Mark W. Vandever, Michelle L. Hladik, Kelly L. Smalling

Natural Resource Ecology and Management Publications

This is the first field study of its kind to combine radio telemetry, passive samplers, and pesticide accumulation in tissues to characterize the amphibian exposome as it relates to pesticides. Understanding how habitat drives exposure in individuals (i.e., their exposome), and how that relates to individual health is critical to managing species in an agricultural landscape where pesticide exposure is likely. We followed 72 northern leopard frogs (Lithobates pipiens) in two agricultural wetlands for insight into where and when individuals are at high risk of pesticide exposure. Novel passive sampling devices (PSDs) were deployed at sites where telemetered frogs ...

Shifting Niche Space In Coastal Landscapes: Spatio-Temporal Patterns Driving Submerged Aquatic Vegetation Across The Northern Gulf Of Mexico, Kristin Elise DeMarco 2018 Louisiana State University and Agricultural and Mechanical College

Shifting Niche Space In Coastal Landscapes: Spatio-Temporal Patterns Driving Submerged Aquatic Vegetation Across The Northern Gulf Of Mexico, Kristin Elise Demarco

LSU Doctoral Dissertations

Identifying distributions of submerged aquatic vegetation (SAV) across the northern Gulf of Mexico (NGOM) coastal landscape necessitates describing ecological processes in estuarine gradients. SAV assemblages are ecological indicators of aquatic ecosystem health; spatial and temporal distributions are strongly correlated to environmental conditions. Many wildlife species, including waterfowl, are dependent on SAV and seeds in NGOM coastal marshes for food and habitat. To understand SAV distributions at multiple spatial and temporal scales a multi-tiered project was designed to collect SAV presence, species assemblage, and cover data, and cores to describe seed food. The first tier sampled inter-annually in the growing seasons ...


Desalination Concentrate Disposal: Ecological Effects And Sustainable Solutions, Ryan Hanley 2018 University of Washington – Tacoma

Desalination Concentrate Disposal: Ecological Effects And Sustainable Solutions, Ryan Hanley

Global Honors Theses

Freshwater availability is a growing global concern, and desalination is often presented as the solution, but from this important technology comes issues of toxic waste. Ecosystems are delicate areas that contain species adapted to that specific location, and any chemical or physical changes can disrupt the fitness of species. The concentrate byproduct waste from desalination plants is toxic to species if the concentrate is not compatible with the receiving water body. A critical review of scientific articles, industry-leading books, conversations with industry experts, and information from the American Membrane Technology Association conference was used to analyze the current knowledge. Species ...


Making And Breaking Trust In Forest Collaborative Groups, Emily Jane Davis, Lee K. Cerveny, Donald R. Ulrich, Meagan L. Nuss 2018 Oregon State University

Making And Breaking Trust In Forest Collaborative Groups, Emily Jane Davis, Lee K. Cerveny, Donald R. Ulrich, Meagan L. Nuss

Humboldt Journal of Social Relations

There has been a recent increase in use of an organized, forest ‘collaborative’ group approach for multi-stakeholder input on federal forestlands in the U.S. West. This approach relies on the creation of shared trust to achieve social agreement. Yet growing critiques suggest a lack of trust in the U.S. Forest Service [Forest Service], between stakeholders, and the collaborative process itself. We conducted three comparative case studies of established forest collaborative groups in Oregon, Washington, and Idaho to ask how trust is created and damaged or broken in this context. We found multiple, interlinked dimensions to trust, including significant ...


Who’S In Charge? The Role Of Power In Collaborative Governance And Forest Management., Patricia B. Orth, Antony S. Cheng 2018 Colorado State University

Who’S In Charge? The Role Of Power In Collaborative Governance And Forest Management., Patricia B. Orth, Antony S. Cheng

Humboldt Journal of Social Relations

Collaborative processes for working toward common management goals between individuals and organizations, despite their differences, emerged as one enduring legacy resulting from the Timber Wars in the American West during the late-1980s and the early 1990s. Power imbalances are often cited as a common problem in collaborative processes and can have a lasting, deleterious impact on the collaborative process and its outcomes. For all its importance, however, there is a yet unfulfilled need to understand the extent to which power and power imbalances affect collaborative relationships. Our research uses a case study approach to qualitatively analyze power dynamics within three ...


The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly 2018 Humboldt State University

The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly

Humboldt Journal of Social Relations

In the wake of the timber wars, communities across the American West have struggled to redefine their relationships to nearby federal forests. The timber-dependent model of the pre-Timber War era, with clear timber targets and economic outputs, has been replaced by more nuanced and less clearly-defined model: ecosystem management. This case study research uses interviews with participants in the Weaverville Community Forest (WCF) to explore the role of a community in managing its nearby federal lands. Momentum for the WCF flowed from a small group of citizens who were invested in the forest despite their cultural and ideological differences regarding ...


An Opportunity To End The Timber Wars: How Collaboration In Southeast Alaska Has Helped To Dissipate Conflict, Diana K. Portner 2018 Meridian Institute

An Opportunity To End The Timber Wars: How Collaboration In Southeast Alaska Has Helped To Dissipate Conflict, Diana K. Portner

Humboldt Journal of Social Relations

Forest management in the Tongass National Forest has been a topic of controversy for decades, due to the result of intense timber extraction in the mid-twentieth century. In recent years, collaborative approaches to management, beginning with a federally chartered advisory committee, have offered opportunities to overcome the seemingly intractable conflict. While a new culture of collaboration is emerging in Southeast Alaska, the region still faces challenges associated with the implementation of these approaches. This commentary explores the history of the conflict, factors that contributed to the success of collaborative approaches to land management in the region, and continued challenges that ...

Finding Solutions Through Politics: One View From Inside The Timber Wars, Erin C. Kelly, Andrea Tuttle 2018 Humboldt State University

Finding Solutions Through Politics: One View From Inside The Timber Wars, Erin C. Kelly, Andrea Tuttle

Humboldt Journal of Social Relations

There are many perspectives of the timber wars, and one perspective that is not frequently documented is that of government bureaucrats – policy makers, regulators, and others who were often caught in the crossfire of opposing sides. This oral history with Dr. Andrea Tuttle is one attempt to describe the Timber Wars from this perspective. On February 25, 2017, I invited Dr. Tuttle to sit down and discuss her history with forest regulation. I asked very few questions and instead listened as she told the history; I ended up with two hours of audio, which I transcribed to over fifteen pages ...

Mensurative Approach To Examine Potential Interactions Between Age-0 Yellow Perch (Perca Flavescens) And Bluegill (Lepomis Macrochirus), Mark A. Kaemingk, David W. Willis 2018 University of Nebraska - Lincoln

Mensurative Approach To Examine Potential Interactions Between Age-0 Yellow Perch (Perca Flavescens) And Bluegill (Lepomis Macrochirus), Mark A. Kaemingk, David W. Willis

Papers in Natural Resources

Bluegill (Lepomis macrochirus) andyellow perch (Perca flavescens) populations are often sympatric in the Great Plains region of the U.S.A. and portions of Canada; however, very little attention has been given to potential interactions between these species for available resources, especially during the early life stages. Relationships between age-0 bluegill and yellow perch growth and relative abundance were explored across multiple lakes and years within the Nebraska Sandhill region, USA. In addition, four habitat patch types (open water, Phragmites spp., Typha spp., Scirpus spp.) were sampled for age-0 bluegill and yellow perch, and food habits were examined for each ...
