Leveraging Mammal Mycophagy To Determine Environmental Drivers Of Truffle Diversity, Brittany Hartsock
Electronic Theses and Dissertations
Many mycorrhizal fungi are hypogeous (truffle-forming), producing underground fruiting bodies. Studying truffles is inherently challenging due to their hidden nature. However, mycophagous mammals provide a unique opportunity to study hypogeous fungi because they rely on truffles as a food source. Although several truffle species have recently been described in the southern Appalachian region, their fruiting patterns remain poorly understood. To address this, we quantified truffle richness and spore loads from 670 Peromyscus scat samples collected across 42 sites spanning an environmental gradient during 2024 in the Blue Ridge Mountains of East Tennessee. We found that truffle richness and spore abundance …

Characterizing Fungal Diversity In The Cumberland River Across Four Urban Sites In Nashville, Tn Using Its Amplicon Sequencing, Leena M. Al-Bunni, Chris Barton, Matthew Heard
Science University Research Symposium (SURS)
Urban freshwater systems provide both recreational opportunities and drinking water resources, making water quality monitoring a critical public health concern. Since 1986, the U.S. Environmental Protection Agency (USEPA) has relied on Escherichia coli (E. coli) as an indicator of fecal and pathogenic contamination. However, the use of E. coli as an indicator does not capture fungi, which also inhabit freshwater systems and can act as pathogens or ecological disruptors. Advances in environmental DNA sequencing, such as Oxford Nanopore’s MinION, now make it possible to characterize these often overlooked fungal communities directly. This study characterizes fungal diversity in the Cumberland River, …

Intraspecific And Intersexual Variations In Morphometrics And Shell Utilization Of Hermit Crab, Areopaguristes Perspicax (Anomura: Diogenidae), Along Karachi Coast, Pakistan, Altaf Hussain Narejo, Noor Us Saher
Journal of Bioresource Management
The present research aimed to evaluate the distribution, sexual dimorphism, and relative growth of Areopaguristes perspicax (Nobili, 1906) along with host shell relationship and selection along the coast of Karachi, Pakistan. Data of hermit crab and gastropod shells were gathered from the four (Manora, Buleji, Sandspit, and Mubarak) coastal sites of two (rocky and sandy) habitats along the Pakistan coast (2017-2019). For morphometric studies, the crabs were sorted, weighed, and measured for the metric variables: cephalothoracic shield length (CSL), hermit crab total length (HCTL), chela length (CL), chela width (CW), and hermit crab weight (HCW), while for host shell relationship, …

The timing of biological events for wildlife species reflects and influences ecological and evolutionary processes and helps guide management actions to meet conservation objectives. Climate change may cause phenological shifts across trophic levels and ecosystems, which can have broad ecological impacts. Shifts may also result in mistiming between management practices based on historical conditions and current biological events, reducing the effectiveness of natural resource management and conservation efforts. We analyzed nesting phenology patterns over recent decades across North America for 44 species of grassland-nesting birds, including waterfowl, upland gamebirds, shorebirds, and passerines, many of which have experienced precipitous population declines. …
Phenotypic Variation Between Surface And Cave-Adapted Poeciliids And Its Effect On Metabolism,

University of Missouri-St. Louis
Phenotypic Variation Between Surface And Cave-Adapted Poeciliids And Its Effect On Metabolism, Karch Knipp, Michael Tobler, Soren Johnson
Undergraduate Research Symposium
Cave-adapted organisms often exhibit pronounced morphological changes relative to their surface counterparts, a phenomenon known as troglomorphy. In Poecilia mexicana (Atlantic molly), these differences include variation in coloration between surface and cave populations. Troglobitic organisms also typically exhibit reduced metabolic rates, likely as an adaptation to environments with low primary productivity. This makes P. mexicana an ideal system for investigating the evolution of metabolic traits. In this study, we leveraged variation in coloration among cave-dwelling mollies to examine potential associations with resting metabolic rate (RMR). Coloration was quantified using PCR values, and individuals were categorized as “yellow” or “non-yellow.” We …

United States Department of Agriculture Wildlife Services: Staff Publications
Double-crested cormorants (Nannopterum auritum) are piscivorous, migratory waterbirds that often conflict with fisheries interests in North America, stemming from depredation effects on fish populations. A new permitting process in the United States allows natural resource agencies to request permits for lethal take of cormorants in special instances like depredation of managed fish stocks. This rule does not include guidance for when cormorant take might be actionable. We developed a hierarchical structured decision making (SDM) framework for evaluating whether, when, and how much cormorant take might be necessary. A broad-scale, or “umbrella,” SDM framework established the overarching problem, objectives …

Paper Wasp Species Polistes Fuscatus (Hymenoptera: Vespidae) Tracks Urban Lead (Pb) Levels More Than Polistes Dominula, Lindsey R. Kemmerling, Anna L. Lovat, Allison A. Hanka, Emilie C. Snell-Rood
The Great Lakes Entomologist
Lead (Pb) is a persistent, toxic pollutant with widespread but inequitably distributed impacts, especially for humans in urban areas. The impacts of lead pollution on other organisms is largely unknown, even as they commonly experience exposure to lead alongside humans. We tested hypotheses regarding the lead concentrations of paper wasps across a gradient of pollution relative to soil and human lead levels, and correlations with wasp body condition. We collected two species of paper wasp across an urban gradient of lead pollution: Polistes fuscatus (Fabricius) (Hymenoptera: Vespidae), native to our study location, and Polistes dominula (Christ), nonnative to our study …

Beyond Better Conditions: Seaweed Farming And The Number Of Sentient Animals In Aquaculture, Shrilaxmi Patil, Matthew Unerman, Wasseem Emam
Animal Sentience
Oldfield & Bonano (2024) (O&B) document how far fish welfare research lags behind welfare research in other animals. We share O&B’s feelings-based concept of welfare and agree that aquaculture seeded this field; but research volume has not scaled with animal numbers: Welfare attention per farmed fish or decapod remains negligible. Along the lines of preceding commentaries (Maia 2024, Mather 2024), we treat farmed aquatic animals as individuals rather than tonnage. We then raise a point so far absent from the commentary on O&B so far: reducing the number of sentient animals entering intensive systems. Coastal seaweed farming, which cultivates non-sentient …

Spatial And Hydrologic Effects Of Climate Change And Urbanization On Freshwater Fish Communities In North Georgia Watersheds, Mayuko Mizutani
Master's Theses
Urbanization and climate change are altering streamflow and land cover across the southeastern United States, threatening freshwater biodiversity in rivers already burdened by impoundments and habitat loss. I investigated how changes in streamflow and land cover might affect fish community biodiversity in the Etowah River watershed of North Georgia. By combining a dataset of fish collections from 1999 through 2019 with contemporaneous land use and daily streamflow, I was able to model fish community responses to urbanization and climate-driven hydrologic changes and then forecast fish community structure under multiple CMIP6 global climate models and greenhouse gas emissions scenarios (SSP2-4.5 and …

Reconstruction Of Copepod Populations In Sierra Nevada Lakes Using The Diatom Fragilaria Cyclopum, Rorie Reisner
All-Inclusive List of Electronic Theses and Dissertations
Copepods are one of the most abundant types of zooplankton, and their populations are often a vital part of the food chain, but their past populations cannot be estimated from lake sediments because their exoskeleton usually does not fossilize. Gull Lake is a glacial lake located in the subalpine region of the Sierra Nevada, California, which stands out due to the presence of the diatom Fragilaria cyclopum, which is rarer in diatom assemblages. Fragilaria cyclopum exclusively grows on copepods in lakes. Diatoms have an opaline silica skeleton that often fossilizes in lake sediments, so we can use this relationship with …

A Comparison Of Ahdrift And Pitfall Traps For Surveying Small Vertebrates, Gabrielle Risko
All-Inclusive List of Electronic Theses and Dissertations
Understanding species occupancy is necessary to inform wildlife management and conservation decisions. To minimize the invasiveness of occupancy studies, some wildlife researchers have deployed game cameras to detect the presence of small vertebrates instead of utilizing stressful traditional live-capture methods. The Adapted Hunt Drift Fence Technique (AHDriFT) is an increasingly popular method for modifying and deploying camera traps to detect small vertebrates; however, no studies have directly compared AHDriFT to traditional pitfall traps operating at the exact same time, even though both are deployed along drift fences to capture small vertebrates. I compared these two methods (pitfall trapping and AHDriFT …

Effects Of Urbanization On Barrier Island Bobcats, Meghan P. Keating
All Dissertations
Urbanization is a leading driver of ecological change and presents unique challenges for carnivores by altering habitat availability, prey communities, and exposure to anthropogenic threats. Although many carnivore species persist in developed landscapes, the ecological and demographic consequences of urbanization often remain poorly understood, particularly over long timescales. Using one of the longest-running studies of a free-ranging carnivore population, I evaluated the effects of urbanization on the behavior, resource use, exposure risk, and population dynamics of bobcats (Lynx rufus) inhabiting a residentially developed barrier island in coastal South Carolina, USA. I first examined temporal and spatial responses to …

The Role Of Phenotypic Plasticity And Bet-Hedging In Coping With Unpredictable Temperature Fluctuations In The Marine Annelid Ophryotrocha Labronica, Gabrielle Dawn Newton
Biological Sciences Theses & Dissertations
Coastal ecosystems are increasingly exposed to unpredictable temperature fluctuations, potentially favoring strategies that buffer populations against environmental uncertainty. This study examines how phenotypic plasticity and diversified bet-hedging contribute to variation in life-history traits under differing thermal predictability in the marine annelid Ophryotrocha labronica. After three generations at 24 °C, broods were reared for three generations under four thermal regimes: constant 24 °C (C24), constant 27 °C (C27), predictable fluctuations (Fp), and unpredictable fluctuations (Fu). Survival was assessed before and after acclimation to evaluate selective pressure among regimes. Age at maturity, fecundity, and growth rate were used to quantify plasticity (trait …
