Bat Habitat Use And Activity In Forests Of Central Louisiana, Jane M. Kunberger
LSU Master's Theses
In the southeastern U.S., where forests are the primary land cover type and trees are often harvested for production purposes, understanding how forestry practices influence bat distributions is critical for bat conservation and management. It is also important for researchers to quantify and report variation in the performance of automated recordings units (ARUs) used to survey for bats because several key features of ARUs (e.g., microphone sensitivity, triggering thresholds) can influence an ARUs ability to detect bat calls. My goals were (1) to examine the influence of forest management practices on seasonal bat species occurrence and activity in central Louisiana, …

The relationship between collared leaf number and growing degree days (GDD) is crucial for predicting maize phenology. Biophysical crop models convert GDD accumulation to leaf numbers by using a constant parameter termed phyllochron (°C-day leaf−1) or leaf appearance rate (LAR; leaf oC-day−1). However, such important parameter values are rarely estimated for modern maize hybrids. To fill this gap, we sourced and analyzed experimental datasets from the United States Corn Belt with the objective to (i) determine phyllochron values for two types of models: linear (1-parameter) and bilinear (3-parameters; phase I and II phyllochron, and transition …

Making Forests, Making Communities: An Ethnography Of Reforestation In Monteverde, Costa Rica, Megan Brown
Anthropology Theses and Dissertations
Reforestation is not just planting trees in the ground. More than net increase in forest cover, reforestation is a complex political endeavor undertaken by both humans and non-humans and a popular climate change mitigation tactic. However, little research has examined the dynamics between selection of specific reforestation strategies, health, and community resilience, particularly with attention to entanglements between the lives of both human and non-human forest dwellers. This ethnographic work, based on six months of in-person fieldwork and six months of digital ethnography, examines reforestation and forest relations in Costa Rica’s Monte Verde zone, a region which experienced widespread deforestation, …

Energy Literacy In Portugal: A System Map And Framework To Increase Energy Literacy Through The Renewable Energy Transition, Molly S. Fox
Independent Study Project (ISP) Collection
Western society lives with a great dependence and an almost simultaneous ignorance of energy consumption (van den Broek, 2019). The systemic landscape of energy knowledge and dissemination is more critical than ever as Portugal races to meet decarbonization goals. This paper fills a knowledge gap by updating the current social landscape of energy literacy in Portugal through a comprehensive system map and framework to increase energy literacy levels through the renewable energy transition. By conducting a semi-systematic literature review, meta-narratives and themes were identified and used to create theoretical concepts, a framework, and a system map. This research found that …

Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene
Student Publications
Coral reefs are biodiversity hotspots that provide humans with extractive ecosystem services like fisheries and non-extractive services like tourism. Though no studies have examined these trade-offs among these services at a global scale, there are now large, open datasets that make this possible. Using these datasets, we asked whether spatial protection and the level of protection (World Database on Protected Areas) impacted coral reef tourism value (Atlas of Ocean Wealth). We also examined whether proximity to regions of high fishing effort, defined as the top 25th percentile of the average annual effort from Global Fishing Watch, impacted tourism values. Since …

Sea Level Rise And Public Perceptions Of Climate Change At Otter Point Creek Estuarine Reserve, Md, Haley A. Bechtel, Meghan L. Junis, Keylen Lucero Garcia
Student Publications
Freshwater tidal marshes are essential stopover points for migratory birds traveling up and down the east coast of North America. Given the importance of these habitats, we examined the effects of sea level rise on vegetation health and vegetation migration at Otter Point Creek Estuarine Reserve. We aimed to test three predictions: 1) vegetation health will decline over time during vegetation growth periods, 2) vegetation migration of less water-tolerant species will occur with movement into higher elevation plots, 3) people will be aware that there are impacts of climate change on species around them and themselves. We used a combination …

Leveraging Land Easements For Grassland Bird Habitat Conservation, Amy N. Marigliano, Hayden E. Dubniczki, Sarah W. Westrick
Student Publications
In addressing the decline of North American grassland bird populations, it is important to consider the various interdisciplinary approaches that can be employed in their conservation. OECMs, or “other effective area-based conservation measures” encompass a wide array of strategies which can be leveraged to conserve natural landscapes and species. Land easements implemented by the Land Conservancy of Adams County (LCAC) are an example of one such strategy. The LCAC seeks primarily to preserve the rural character of Adams County but has more recently turned their focus toward environmental conservation. In partnering with the Land Conservancy, this case study aimed to …

Economic Consequences Of The Wolf Comeback In The Western United States, Dana Hoag, Stewart W. Breck, Kevin Crooks, Becky Niemiec
United States Department of Agriculture Wildlife Services: Staff Publications
Gray wolves were eradicated from most of the United States in the 1940’s but have made a comeback in parts of their historic range over the last two decades. First reintroduced into the Greater Yellowstone Ecosystem and central Idaho in the mid-1990’s, wolves have subsequently dispersed into at least 7 western states. Coloradoans became the latest state to take interest in bolstering wolf populations, as residents passed a ballot initiative in November 2020 to reintroduce a self-sustaining population of gray wolves by the end of 2023. Conflicts between people in rural areas that might incur costs (such as livestock loss) …

Protected areas are intended as tools in reducing threats to wildlife and preserving habitat for their long-term population persistence. Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals …

Media Coverage Of Anthropogenic Climate Change: Analysis Of Coverage, Issues, And Implications For Public Engagement And Government Policy, Renee Farmer
Senior Honors Theses
Media coverage of climate change is responsible for shaping both public understanding and government policies regarding the environment. The public relies on the media to translate the oftentimes complex terminology, processes, and implications of environmental research and findings. Unfortunately, miscommunication frequently occurs as the media seek to bridge this knowledge gap, with implications including hostile public sentiment, failure to take necessary action, and ineffective or harmful governmental policies. This thesis will provide an overview of how the media cover climate change, including analyses of both poor and successful coverage of issues, identification of risks and reoccurring problems present in media …

Studying ecosystem dynamics is critical to monitoring and managing linked systems of humans and nature. Due to the growth of tools and techniques for collecting data, information on the condition of these systems is more widely available. While there are a variety of approaches for mining and assessing data, there is a need for methods to detect latent characteristics in ecosystems linked to temporal and spatial patterns of change. Resiliencebased approaches have been effective at not only identifying environmental change but also providing warning in advance of critical transitions in social-ecological systems (SES). In this study, we examine the usefulness …
