Effects Of Stream Permanence On The Stoneflies (Plecoptera) Of The Mammoth Cave Region, Taylor Mcroberts
Effects Of Stream Permanence On The Stoneflies (Plecoptera) Of The Mammoth Cave Region, Taylor Mcroberts
Masters Theses & Specialist Projects
Stoneflies (Plecoptera) are often associated with cold perennial streams, but many species also inhabit intermittent streams that experience reduced or lack of flow during summer and autumn. In this study the influence of stream permanence on stonefly assemblage composition and spatial distribution in the Mammoth Cave region, Kentucky, USA, was addressed based on a 14 month sampling regime from the fullest range of stream sizes and habitable flow regions available. Adult stoneflies were collected monthly at Mammoth Cave National Park and the Western Kentucky University Green River Preserve. Collections were done from December 2018–October 2019 using a standard timed protocol …
Tropical Pitcher Plants (Nepenthes) Act As Ecological Filters By Altering Properties Of Their Fluid Microenvironments, Kadeem J. Gilbert, Leonora S. Bittleston, Wenfei Tong, Naomi E. Pierce
Tropical Pitcher Plants (Nepenthes) Act As Ecological Filters By Altering Properties Of Their Fluid Microenvironments, Kadeem J. Gilbert, Leonora S. Bittleston, Wenfei Tong, Naomi E. Pierce
Biology Faculty Publications and Presentations
Characteristics of host species can alter how other, interacting species assemble into communities by acting as ecological filters. Pitchers of tropical pitcher plants (Nepenthes) host diverse communities of aquatic arthropods and microbes in nature. This plant genus exhibits considerable interspecific diversity in morphology and physiology; for example, different species can actively control the pH of their pitcher fluids and some species produce viscoelastic fluids. Our study investigated the extent to which Nepenthes species differentially regulate pitcher fluid traits under common garden conditions, and the effects that these trait differences had on their associated communities. Sixteen species of Nepenthes …
The Gut Microbiota Of A Wild American Black Bear (Ursus Americanus) Population, Sierra Gillman
The Gut Microbiota Of A Wild American Black Bear (Ursus Americanus) Population, Sierra Gillman
All NMU Master's Theses
The gut microbiome (GMB), the mutualistic microbial communities located in the gastrointestinal tract (GIT), has co-evolved in vertebrates to perform micro-ecosystem services to facilitate physiological functions. Despite the key role of the GMB in host health, wildlife managers have been slow to consider the ramifications of anthropogenic pressures to wildlife-GMB diversity. For example, although diet is one of the most influential determinants of a host’s GMB, many wildlife agencies allow baiting with human-provisioned foods to facilitate the harvest of wildlife such as American black bear (Ursus americanus). Additionally, much of our knowledge of wildlife-GMB relationships is based on …

2020 Symposium Posters
The gut microbiome plays an essential role in the overall health of organisms. However, the presence and abundance of these microbes may be altered by environmental factors, such as exposure to pesticides. The goals of this project were to understand 1) the prevalence of pesticide residues in honey bees in eastern Washington, and 2) the impact of pesticides to the honey bee gut microbiome. Accordingly, we tested bees from 24 hives among six sites across eastern Washington. High-performance liquid chromatography-mass spectrometry (HPLC-MS) was used to detect the presence and concentration of six commonly used agricultural pesticides: Carbaryl, Chlorpyrifos, Coumaphos, Cypermethrin, …

Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Electronic Theses and Dissertations
Land use activities have caused disturbances that affect the quality of freshwater ecosystems worldwide. How the influences of land use along an environmental gradient and the associated environmental variables that may influence stream diversity and function is unclear. We address these issues by studying biodiversity, abundance, and functional diversity of macroinvertebrates across different land types along a gradient in Colorado, USA. We also address how diversity may change along an elevation gradient by analyzing previously published macroinvertebrate research. We found evidence that land use and disturbance are stronger explanations of changes in macroinvertebrate communities, rather than elevation. Functional trait patterns …
Practicalities Of Re-Wilding, William C. Mcgrew
Practicalities Of Re-Wilding, William C. Mcgrew
Animal Sentience
Re-wilding large-brained, intelligent mammals dependent on social learning to acquire survival skills is challenging. Each reintroduced species has different needs, but basic questions relating to essential aspects of successful release such as subsistence remain the same. Here I pose 12 ecologically and ethologically based questions that should be addressed (if not already done).
Diversity Analysis Of Soil Fungus Communities In Disturbed, Nursery, And Mature Forest Conditions, Dana Whitmore
Diversity Analysis Of Soil Fungus Communities In Disturbed, Nursery, And Mature Forest Conditions, Dana Whitmore
All Master's Theses
Populations of soil fungi were examined in Derby Canyon Natives, Coeur d’Alene Forest Service nursery, Swamp Lake, and the Keechelus Lake wildlife overcrossing soils. All sampling sites were connected by their relation to the revegetation and native soil plug inoculation of the wildlife overpass. This study was an effort to describe soil fungi communities present on the overpass before plant introduction, those that plants would be bringing in their pots, and the fungi that could be introduced via soil plug transplantation. DNA was extracted from soil samples, then sequenced using next-generation sequencing methods, allowing for the analysis of species richness …
The Importance Of Surface Mining As A Landscape Variable In Shaping Wild Bee Communities In Central Appalachian Forests, Amanda Sheryl Dunaway
The Importance Of Surface Mining As A Landscape Variable In Shaping Wild Bee Communities In Central Appalachian Forests, Amanda Sheryl Dunaway
Online Theses and Dissertations
Anthropogenic disturbance has led to widespread losses in biodiversity. Native bees (Hymenoptera, Apoidea) provide essential pollination services and have been declining in abundance dramatically in recent years. One potential cause of these declines is anthropogenic disturbance. Eleven sites were established in Southeastern Kentucky, U.S.A. where surface mining for coal is common. Data was analyzed using generalized linear mixed-effect models to detect the most important landscape scale variables, including mining, in shaping bee communities. Bee species richness was significantly lower on sites that contained surface mines, but abundance was similar between mined and unmined sites. The proportion of each nesting group …
Evidence Of Local Adaptation To Climate In An Invasive Ectotherm: A Study On The Eurasian Gypsy Moth (Lymantria Dispar) In North America, Phillip M. Gibbs
Evidence Of Local Adaptation To Climate In An Invasive Ectotherm: A Study On The Eurasian Gypsy Moth (Lymantria Dispar) In North America, Phillip M. Gibbs
Theses and Dissertations
Invasive species exist in nearly every ecosystem both terrestrial and aquatic. Improving our understanding of the mechanisms that shape the ability of these organisms to physiologically cope with their surroundings will be crucial to preparing for future impacts of climate change. The Gypsy Moth (Lymantria dispar) has been expanding its range across North America over the last 100+ years since its arrival in Medford, Massachusetts. This study quantifies upper thermal limits (UTL) across 8 different populations of L. dispar in North America and seeks to determine if signals of local adaptation to climate across a latitudinal gradient may …
Is Context Dependency Imperative To Understanding The Impacts Of Invasive Plants?, Brendan B. Haile
Is Context Dependency Imperative To Understanding The Impacts Of Invasive Plants?, Brendan B. Haile
Masters Theses
Introduced exotic species have a tendency to become invasive and impact local biological communities. Invasions often impact community attributes such as cover and species richness, but these factors may also regulate patterns of invasion. In such cases, impacts may be dependent on the invasion context. We used data from the Buell-Small Succession Study, a long-term permanent plot study in the piedmont region of New Jersey, to document context dependency in invasion. To do this, we analyzed the factors that affected the colonization and growth of four invasive species, Alliaria petiolata, Lonicera japonica, Microstegium vimineum and Rosa multiflora, as well …
The Effects Of Low-Level Pharmaceuticals On Stream Biofilm Structure And Function Across A Land-Use Gradient In Streams Of The Huron River Watershed, Elizabeth Mae Stover
The Effects Of Low-Level Pharmaceuticals On Stream Biofilm Structure And Function Across A Land-Use Gradient In Streams Of The Huron River Watershed, Elizabeth Mae Stover
Master's Theses and Doctoral Dissertations
Pharmaceuticals and personal care products (PPCPs) are a contaminant class of worldwide concern. Their environmental omnipresence indicates they may be a potential source of global change, and ecosystem-scale impacts at non-lethal levels have not been fully explored. We used stream biofilms to assess ecosystem responses to PPCPs. Biofilms were cultivated in streams draining areas of different land use and then exposed to triclosan, diphenhydramine, and sulfamethoxazole-trimethoprim treatments. We found evidence that low levels of these PPCPs affected some, but not all, aspects of biofilm processes and bacterial community composition. Bacterial carbon uptake was reduced (p = 0.06) and we found …

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human– vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts …
