Application Of Excitation-Emission Matrices To Fluorescent Dye Tracing Of Groundwater Flow, Cayla M. Baughn 2020 Western Kentucky University 81818app手机版下载

Application Of Excitation-Emission Matrices To Fluorescent Dye Tracing Of Groundwater Flow, Cayla M. Baughn

Masters Theses & Specialist Projects

81818app手机版下载Fluorescent dye tracing of groundwater is a technique employed particularly in carbonate rock karst regions to examine karst hydrology by mapping underground flow paths. It is important to understand the hydrology of karst environments because solutionally-enlarged conduits may allow the rapid influx of contaminants into the groundwater system. Fluorescent dye tracing involves the injection of a fluorescent dye into an appropriate injection site (sinking streams, sinkholes, or even through soil flushed with water) and is followed by sampling at sites where the dye may be recovered (typically springs). Various methods exist by which sampling may occur, but all methods ultimately ...

Instability Of Glucocorticoid Metabolites In Coyote Scats: Implications For Field Sampling, Erika T. Stevenson, Eric M. Gese, Lorin A. Neuman-Lee, Susannah S. French

Human–Wildlife Interactions

Studying physiologic stress responses can assist in understanding the welfare of animals. One method of measuring the physiologic stress response is evaluating concentrations of glucocorticoid metabolites in feces. Previously, using an adrenocorticotropic hormone challenge, we found fecal glucocorticoid metabolite levels were a reliable indicator of physiologic stress response in coyotes (Canis latrans81818app手机版下载). We determine whether glucocorticoid metabolite concentrations remain stable when collecting feces over a 2-week period, a timeframe commonly used in scat surveys for wild canids. We collected feces from 6 captive coyotes maintained at the U.S. Department of Agriculture, Wildlife Services, National Wildlife Research Center, Predator Research ...

The Concept Of Natureculture Document: A Conceptual Exploration Of Seeds, Embodied Information, And Unconventional Records, Marc Kosciejew

Journal of Contemporary Archival Studies

81818app手机版下载Seedbanks, or so-called archival arks of the apocalypse, are addressing accelerating anthropocentric alterations to the environment by collecting, storing, and preserving seeds. These are specialized archival repositories that approach, frame, and use seeds as documents for agricultural and scientific research, classification and preservation work, and various other archival and administrative purposes. Seedbanks indeed are archives of unconventional records.

This article introduces the concept of natureculture document as a framing device in which to help analyze the documentary status of objects that are not necessarily or usually considered as documents or having documentary characteristics. This concept, coupled with its interdisciplinary theoretical ...


Factors Influencing Apparent Nest Success In Eastern Bluebirds, Katelynn Gierlinger 2020 State University of New York College at Brockport

Factors Influencing Apparent Nest Success In Eastern Bluebirds, Katelynn Gierlinger

Senior Honors Theses

Collection of basic breeding biology data and analysis of factors that can impact the apparent nest success of passerines is critical in tracking population dynamics and making decisions concerning conservation. The Eastern Bluebird (Sialis sialis) is one species of concern whose declines in abundances fueled the common practice of establishing artificial nest boxes. I carried out my study in 2019 on the SUNY Brockport campus using 20 Audubon and 20 Peterson nest boxes to investigate what variables may impact fledgling success, including egg and nestling traits as well as site characteristics. Egg mass and volume tended to be larger in ...


Pollinator Communities On Public Lands: Creating New Opportunities For Management, Jacob Kearney 2020 State University of New York College at Brockport 81818app手机版下载

Pollinator Communities On Public Lands: Creating New Opportunities For Management, Jacob Kearney

Senior Honors Theses

Because butterfly species such as monarchs (Danaus plexippus) are declining, they have received renewed public and scientific interest. Butterflies provide important ecological services, such as pollination. Understanding their ecology is vital for proper conservation and management, with targeted management on public lands increasing in the last few decades. To determine useful management strategies for butterfly populations on public lands, I investigated butterfly use in two “non-traditional” sites utilized by butterflies at Montezuma National Wildlife Refuge (MNWR): a marsh in full drawdown phase (MP) and a marsh in partial drawdown phase (SF). I also investigated butterfly use at an upland field ...


Examining How The Presence Of Invasive Swallow-Wort (Vincetoxicum Sp.) Affects The Abundance Of Earthworms, Samantha Dube 2020 State University of New York College at Brockport

Examining How The Presence Of Invasive Swallow-Wort (Vincetoxicum Sp.) Affects The Abundance Of Earthworms, Samantha Dube

Senior Honors Theses

Swallow-wort (Vincetoxicum sp.), an invasive plant in Western New York, outcompetes native species such as common milkweed (Asclepias syriaca). Swallow-wort may release allelochemicals that change the composition of the soil to benefit its own growth. Earthworms are also an invasive species in our area. In excess, they can till the soil too much, drying it out and making it difficult for any plants to grow. While overturning the soil has its benefits, too many worms can cause the soil horizons to merge, displacing minerals and loosening up the foundation for most plants. Because no one had ever studied the relationship ...

Synergy Of Thermochemical Treatment Of Dried Distillers Grains With Solubles With Bioethanol Production For Increased Sustainability And Profitability, Samuel O’Brien, Jacek A. Koziel, Chumki Banik, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

The bioethanol industry continues improving sustainability, specifically focused on plant energy and GHG emission management. Dried distiller grains with solubles (DDGS) is a byproduct of ethanol fermentation and is used for animal feed. DDGS is a relatively low-value bulk product that decays, causes odor, and is challenging to manage. The aim of this research was to find an alternative, value-added-type concept for DDGS utilization. Specifically, we aimed to explore the techno-economic feasibility of torrefaction, i.e., a thermochemical treatment of DDGS requiring low energy input, less sophisticated equipment, and resulting in fuel-quality biochar. Therefore, we developed a research model that ...
