Modeling Postfire Effects On Snow Albedo And Forest Recovery Over A Chronosequence Of Burned Forests In The Triple Divide Region Of The Rocky Mountains, Anton J. Surunis

Dissertations and Theses

Wildfires impact snow albedo, forest cover, and forest structure and thus snow melt rate and snowpack supply for as long as 15 years following burn. These effects have not been quantified at fine spatial resolutions and long time periods at a watershed scale. I modeled the effects of postfire effects on snow albedo, snow-mass energy balance, and resulting snow-water equivalent (SWE) depth over a long-time scale and at a fine spatial resolution. Using a spatially and temporally distributed snow evolution model called SnowModel, I modeled postfire effects on snow albedo and forest structure over postfire recovery within 8 forest fires …

Relating Plant Community Structure To Carbon Dynamics In Semiarid Grasslands, Theodore D. Roper

Biology ETDs

Understanding how fine-scale changes in soil characteristics and plant community composition affect ecosystem functioning is key to predicting how biome shifts will affect regional and global carbon cycling. This is crucial in the dryland biomes of the US Southwest, projected to be one of the regions most affected by climate change. We examined fine-scale drivers of ecosystem function within two biomes – a Chihuahuan Desert grassland and Plains/Chihuahuan Desert ecotone – via long-term vegetation data, micrometeorological data, eddy covariance carbon flux measurements, and soil water and texture, finding that the ecotone site had over 30% higher soil water content, over …

Impact Of Oil And A Tropical Cyclone On An Omnivore And Herbivore Population In Salt Marshes Of Louisiana, Hannah K. Gordon

LSU Master's Theses

Terrestrial arthropods are the ideal ecological indicators for the health of a salt marsh. Salt marshes are under extreme continuous stressors including climate change, land loss, oil spills, and tropical cyclones. Such stressors impact trophic and species level interactions, food resources, dispersal and population size of insects. In the present study, we collected terrestrial arthropods from eleven sites around Barataria Bay, five sites were oiled and five sites were unoiled, to determine the impact of the redistribution of oil from the Deepwater Horizon oil spill. Site C6 was excluded from the oiled and unoiled data because it was in close …

Prediction Of Cultivation Areas For The Commercial And An Early Flowering Wild Accession Of Salvia Hispanica L. In The United States, Mohammad Hassani, Thomas Piechota, Hagop S. Atamian

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Salvia hispanica L., commonly known as chia, is a plant-based alternative to seafood and is rich in heart-healthy omega-3 fatty acid, protein, fiber, and antioxidants. In the Northern Hemisphere, chia flowering is triggered by the fall equinox (12-h light and dark, early October) and the seeds mature after approximately three months. Chia is sensitive to frost and end of season moisture which limits its cultivation to small areas in regions with temperate climate. The U.S. chia import has increased considerably over the years; however, chia is not widely cultivated in the United States. This study used the historical U.S. temperature …

Dual Isotopic (O & N) Approach In The Assessment Of No3- Pollution In An Urban River, Abongwa T. Pride, Walter Den, Aarin Teague

Water Resources Science and Technology Faculty Publications (Archived)

Deterioration of urban waterways has become a major environmental concern as management and recreational goals are often hampered by poor water quality. The San Antonio River (TX, USA), whose upper reaches, including its headwaters, pass through a highly urbanized community, is vulnerable to pollution from a myriad of anthropogenic activities within its initial 17-km stretch. This investigation applied a dual-isotope approach to characterize water samples collected during the wet season (May–June, 2019) in order to assess the potential sources of nitrate in the urban stretch of river. The δ¹⁵N-_NO3 and δ¹⁸O-_NO3 values ranged from …

The Impact Of Human Activity On Coastal Zones With Elise Granek, Elise F. Granek

PDXPLORES Podcast

In this episode of PDXPLORES, Professor Elise Granek discusses the coastal zone- transition zones between land, sea, and atmosphere. These ecosystems provide vital ecological, cultural, and commercial benefits. Around the world, they are home to a vast number of species, support critical industries, and sustain the cultural heritage of the people who have called them home. As with all ecosystems, they are vulnerable. Given the intense human dependence on the continued viability of these coastal ecosystems, understanding the impact of human activity on the species that inhabit them is essential to identifying solutions to address the suite of impacts.

Local And State Climate Initiatives In Louisiana Since 2005: Content And Thematic Analyses, Jessie F. Parrott

LSU Master's Theses

Louisiana is uniquely exposed to severe weather because of its geography and climate. Louisiana’s extreme weather is exacerbated by anthropogenic climate change, which will worsen in the future. The risks its population and environment are exposed to has generated several policies and planning documents, nine of which are analyzed in this thesis. Three plans are from the state level, three are from the parish level, and three are from the urban (New Orleans) level. These planning documents pose various adaptation and mitigation actions to ameliorate and address multiple climate issues. These actions utilize specific mitigation strategies. The content and thematic …

Science Of The Total Environment, Benjamin Linhoff

United States Geological Survey: Staff Publications

Recently, the subsoils of ephemeral stream(arroyos) floodplains in the northern Chihuahuan Desert were discovered to contain large naturally occurring NO₃⁻ reservoirs (floodplain:~38,000 kg NO₃-N/ha; background:~60 kg NO₃-N/ha). These reservoirs may be mobilized through land use change or natural stream channel migration which makes differentiating between anthropogenic and natural groundwaterNO₃⁻sources challenging. In this study, the fate and sources of NO₃⁻ were investigated in an area with multiple NO₃⁻ sources such as accidental sewer line releases and sewage lagoons aswell as natural reservoirs of subsoil NO₃⁻. …

Seasonal Climatic Niche And Migration Movements Of Double-Crested Cormorants, D. Tommy King, Guiming Wang, Fred L. Cunningham

United States Department of Agriculture Wildlife Services: Staff Publications

Avian migrants are challenged by seasonal adverse climatic conditions and energetic costs of long-distance flying. Migratory birds may track or switch seasonal climatic niche between the breeding and non-breeding grounds. Satellite tracking enables avian ecologists to investigate seasonal climatic niche and circannual movement patterns of migratory birds. The Double-crested Cormorant (Nannopterum auritum, hereafter cormorant) wintering in the Gulf of Mexico (GOM) migrates to the Northern Great Plains and Great Lakes and is of economic importance because of its impacts on aquaculture. We tested the climatic niche switching hypothesis that cormorants would switch climatic niche between summer and winter …

Using Dietary Additives To Improve Palatability Of Diets Containing Single‐Cell Protein From Methanotrophic Bacteria In Yellowtail Kingfish (Seriola Lalandi) Diets, Luke Pilmer, Lindsey Woolley, Alan J. Lymbery, Michael Salini, Gavin Partridge

Fisheries Research Articles

Single-cell protein (SCP) derived from methanotrophic bacteria has significant potential as a fishmeal alternative in aquafeeds. However, SCP has known palatability issues, to overcome these issues tuna hydrolysate and garlic powder were tested as palatability enhancers against basal diets without these additives. This study tested the inclusion of SCP at four dietary levels of 0%, 10%, 20% and 30%, representing 0%, 25%, 50% and 75% fishmeal replacement in juvenile yellowtail kingfish (Seriola lalandi) (YTK) diets. YTK were fed these diets in triplicate over 35 days. Compared with the control diet, fish fed the SCP10% diet ate less feed, …

Dossier: The Hunger Plan: The Holocaust, Resource Scarcity, And Preventing Genocide In A Changing Climate, Emily Sample

Genocide Studies and Prevention: An International Journal

Nazi leadership sought to exploit the biological fear of starvation and scapegoat the Jewish population and other “useless eaters” for taking more than their fair share. The Nazis utilized and hyperbolized well-known prejudices against Jewish people, and entrenched narratives of Jewish parasitism as a threat to current and future German lives. In this analysis, food scarcity was one of several reasons for the Holocaust, and the first step to seeking Lebensraum for pure Germans to live to the highest international standard. This article will focus on different aspects of the complex antisemitic rhetoric surrounding issues of resource scarcity, including Hitler’s …

Breeding Ecology Of Mottled Ducks In Southwestern Louisiana, Elizabeth Sophia Bonczek

LSU Doctoral Dissertations

Mottled ducks are a resident species found in the southern United States that rely on coastal marsh and associated habitat to fulfill the needs of the entirety of their annual cycle. Population monitoring has revealed declines in western Gulf Coast (WGC) mottled ducks since 2008. Mottled duck populations are influenced by survival and recruitment, and changes in these factors may contribute to population declines. The overarching goal of this project was to identify the mechanisms potentially limiting WGC mottled ducks.

I captured adult female mottled ducks during molt on Rockefeller Wildlife Refuge and adjacent lands in southwestern Louisiana from 2017–2019. …
