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, Karch Knipp, Michael Tobler, Soren Johnson
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 …

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 …

A Comparison Of Ahdrift And Pitfall Traps For Surveying Small Vertebrates, Gabrielle Risko
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 …
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Animal Sentience
Birch's (2024) The Edge of Sentience identifies sentience candidates primarily through the pain-focused LSE Criteria. Yet, as Birch himself notes in Proposal 17, sentience is not pain. We argue that statutory welfare protections must therefore reach beyond pain, and that the right tool for doing so is Birch et al.’s (2020) dimensionality framework, which characterises conscious experience across five domains. Used together, the LSE Criteria establish that welfare is at stake, while the dimensionality framework maps what is at stake beyond pain to provide a taxon-specific profile of where captivity impoverishes experience. We apply this approach to invertebrate welfare and …
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Animal Sentience
Several commentaries on the Oldfield & Bonano (2024) target article proposed that natural behavior should play a larger role in assessing the welfare of fishes in zoos and aquariums. However, the natural-behavior concept of animal welfare has been widely criticized because natural behaviors do not necessarily improve welfare, and unnatural behaviors do not necessarily reduce it. I review the three major concepts of animal welfare — physical health, natural behavior, and affect/feelings — and argue that behavior patterns, whether natural or otherwise, should be evaluated according to their effects on health and subjective experience. Using the affect/feelings concept and the …
Feeding Ecology In Coastal Systems, Randi L. Cannon
Feeding Ecology In Coastal Systems, Randi L. Cannon
Graduate Theses and Dissertations (2019 - present)
Oysters (Crassostrea virginica) are critical foundation species in estuaries, providing numerous ecological and economic benefits. However, oyster populations have diminished worldwide. Effective oyster restoration and aquaculture require a mechanistic understanding of the physiological and environmental factors that govern oyster feeding, growth, and resilience under changing coastal conditions. We investigated how oyster ploidy and environmental conditions influenced oyster feeding and investigated how changes in abiotic conditions affected behavioral performance of oyster drills (Stramonita spp.), a key oyster predator. To better understand feeding responses and behaviors of both predator and prey we 1) used in-situ filter feeding assays to determine if feeding …
Aggression And Fish Welfare: Challenges And Opportunities, Christine M. Soper, Peter D. Dijkstra
Aggression And Fish Welfare: Challenges And Opportunities, Christine M. Soper, Peter D. Dijkstra
Animal Sentience
Oldfield & Bonano’s (2024) [O&B] target article discusses the wellbeing and sociality of bony fishes. Many fish species, such as cichlids, are not only social but territorial. Aggression is normal, but territorial aggression in a captive environment can have a negative impact on welfare. Aggression-related injuries and deaths are prevalent in pet stores as well as research settings. We discuss the need to develop effective methods to minimize the negative consequences of aggression.
Hot Cities, Cool Lizards: Do College Campuses Create Urban Oases For Wildlife?, Ethan Heck, Javier Monzon Phd
Hot Cities, Cool Lizards: Do College Campuses Create Urban Oases For Wildlife?, Ethan Heck, Javier Monzon Phd
Seaver College Research And Scholarly Achievement Symposium
Urban wildlife may experience stress due to the Urban Heat Island Effect. On the other hand, urban wildlife may experience relief, especially in arid ecosystems, due to the Urban Oasis Effect. The objective of this study was to test whether college campuses in southern California act as heat islands or oases for wildlife. We analyzed how temperature and water availability of microhabitats relate to the physiology of a widespread and common cold-blooded animal, the Western Fence Lizard (Sceloporus occidentalis). We logged environmental conditions in lizard hotspots at 11 university campuses across southern California and measured the hydration of lizards at …
Fish Community Assessment Of Goose Pond Natural Area, Macy Sparks
Fish Community Assessment Of Goose Pond Natural Area, Macy Sparks
ATU Scholars Symposium
Natural areas play an integral role in the preservation and conservation of unique ecosystems (i.e., natural wetlands). However, many natural areas have never had a biological inventory of species utilizing these areas. Goose Pond Natural Area (Conway County and Pope County, Arkansas) is one of those natural areas lacking species occurrence data. We addressed this data gap by sampling fish species across multiple habitat types (shallow woody wetland, open grassy wetland, and stream). We employed multiple gear types (mesh umbrella minnow traps, seines, gill nets, mini-fyke nets, and backpack electrofishing) in hopes of increasing species detection. Sites within the natural …
Smell Over Sight: Determining Levels Of Olfactory Gene Expression Between Surface And Subterranean Eurycea Salamanders, Sonia Cerrillo, Iliana Melendez, Naomi Ramirez
Smell Over Sight: Determining Levels Of Olfactory Gene Expression Between Surface And Subterranean Eurycea Salamanders, Sonia Cerrillo, Iliana Melendez, Naomi Ramirez
Posters - 2026
In the karst aquifers of central Texas, including the Edwards and Trinity systems, organisms live in an environment defined by constant temperatures, total darkness, and scarce food resources. These conditions have driven the evolution of salamanders in the genus Eurycea, particularly those that have adapted to subterranean life. Cave-dwelling species like Eurycea rathbuni exhibit hallmark “blind salamander” traits, including educed eyes, loss of pigmentation, and flattened head morphology. In contrast, surface-dwelling relatives such as Eurycea nana and Eurycea sosorum retain fully developed eyes and pigmentation, while some species like Eurycea latitans display both surface and subterranean forms across different populations.
Temporal Avoidance By Gray Foxes Reflects Growing Pressure From Expanding Coyotes In The Neotropics, Madison Odenbach
Temporal Avoidance By Gray Foxes Reflects Growing Pressure From Expanding Coyotes In The Neotropics, Madison Odenbach
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Coyotes (Canis latrans) are rapidly expanding their range towards South America, potentially threatening the world’s highest canid diversity residing on that continent. A better understanding of their interactions with native species is needed to anticipate potential competitive impacts. In Costa Rica, native gray foxes (Urocyon cinereoargenteus) likely occupy a similar niche to the coyote newcomer, yet little data exists on their interactions in tropical ecosystems. We hypothesized the two species separate temporally to minimize the potential for competition in our study area, given preliminary data suggesting high spatial overlap (57.1% of coyote-detected sites overlap with fox-detected …

Multiple Burn And Forest Characteristics Affect Gray Fox (Urocyon Cinereoargenteus) Occurrence Following A California Megafire, Amida Zohar Verhey
Multiple Burn And Forest Characteristics Affect Gray Fox (Urocyon Cinereoargenteus) Occurrence Following A California Megafire, Amida Zohar Verhey
Cal Poly Humboldt theses and projects
In western North American forests, predator communities are faced with changing fire regimes and increased fire severity and size, particularly with megafires (>10,000 ha). As some wildlife communities may restructure following the loss of apex consumers, understanding post-fire space use of mid-trophic carnivores may inform species composition in these forests. I compared gray fox (Urocyon cinereoargenteus) occupancy in and around the 2021 Dixie Fire, the largest single-ignition fire in California state history, to examine which spatially variable burn and forest characteristics affected the space use of a widespread generalist mesopredator. Using 210 camera traps placed in 2023, …

Graduate Theses and Dissertations (2019 - present)
This study presents the first comprehensive taxonomic and ecological investigation of endophytic fungi (EF) associated with the submerged aquatic macrophyte Vallisneria neotropicalis in the southern United States. Over a 12 month period, from April 2023 to March 2024, leaf samples were collected from two distinct sites in Mobile Bay, Alabama a disturbed, brackish Causeway location and a cleaner, less impacted site at Meaher State Park. Using culture dependent methods, a total of 257 fungal endophytes were isolated from 1,200 leaf segments. All isolates belonged to the phylum Ascomycota, distributed across 3 classes, 6 orders, 10 families, and 19 taxa. The …
Attributes Of Artificial Wetlands Colonized By Ambystoma Maculatum On A Virginia Surface Mine, Hunter Hill, Garrett Stiltner, Walter H. Smith
Attributes Of Artificial Wetlands Colonized By Ambystoma Maculatum On A Virginia Surface Mine, Hunter Hill, Garrett Stiltner, Walter H. Smith
Virginia Journal of Science
Landscapes impacted by surface mineral extraction present a range of artificial wetland habitats potentially useable by pool-breeding amphibians, although little information exists in the literature detailing which attributes influence breeding site selection by wetland amphibian specialists in post-mined landscapes. We compared attributes of artificial wetlands consistently used and unused as oviposition sites by Spotted Salamanders (Ambystoma maculatum) over a six-year period on a 120-ha former surface mine in Wise County, Virginia, USA. Salamanders non-randomly selected wetlands as oviposition sites, with one-third of available wetlands within the study area showing evidence of ovipositioning. Wetlands used as breeding sites were …
First Report Of Fibropapillomatosis And Critical Habitat Use In Green Sea Turtles In Curaçao, M. Tripepi, I. J. R. Van Veghel, A. D. Vreugdenhil, E. Brunelli
First Report Of Fibropapillomatosis And Critical Habitat Use In Green Sea Turtles In Curaçao, M. Tripepi, I. J. R. Van Veghel, A. D. Vreugdenhil, E. Brunelli
College of Life Sciences Faculty Papers
Fibropapillomatosis, a disease affecting green sea turtles (Chelonia mydas), has been documented in many regions of the world, including the Caribbean, but has not been scientifically reported in Curaçao until now. The present study utilized VHF telemetry in Caracas Bay, Curaçao, to track green sea turtles, both healthy and affected by fibropapillomatosis, with the objective of ascertaining their foraging locations. VHF telemetry proved to be a pivotal method for assessing habitat use in areas characterized by limited visibility and high boat traffic, conditions that present significant challenges for divers and snorkellers attempting to access the area. The results …
Distributional Records Of Blanding’S Turtles (Emydoidea Blandingii) In Nebraska, Sam Thede, Dan Fogell, Keith Geluso
Distributional Records Of Blanding’S Turtles (Emydoidea Blandingii) In Nebraska, Sam Thede, Dan Fogell, Keith Geluso
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Blanding’s Turtle (Emydoidea blandingii) is a species of concern in North America as many populations have declined across its distribution. Environmental factors associated with alteration of natural ecosystems have played a role in declines leading to many isolated populations. Most populations exist in the Great Lakes region with a number of outlying populations, such as Nebraska. Understanding the current distribution of the species will facilitate regional management strategies to protect this species into the future. In Nebraska, Blanding’s Turtles were known from 23 counties prior to this study. Herein, we report on eight new county records, five (Blaine, …
More Equal Than Others: Taxonomic Bias In Animal Management, Barrett L. Christie
More Equal Than Others: Taxonomic Bias In Animal Management, Barrett L. Christie
Animal Sentience
Oldfield & Bonano (2024) point out not only the scarcity of research on fish welfare but also significant taxonomic bias in broader research on these species. This bias extends to the management practices of aquaria and zoos, where the focus is on higher vertebrates. More resources need to be allocated to research to address this disparity. We also need to develop welfare constructs that recognize the inherent differences between aquatic and terrestrial species, taking into account the unique ecological contexts and behavioral patterns of fishes.
Impact Of Unconventional Gas Extraction On Tributaries Of Tenmile Creek, Greene County, Pennsylvania: A 12-Year Perspective, Christian L. Beall
Impact Of Unconventional Gas Extraction On Tributaries Of Tenmile Creek, Greene County, Pennsylvania: A 12-Year Perspective, Christian L. Beall
Electronic Theses and Dissertations
Much of southwestern Pennsylvania has been central to a rapid increase in development for unconventional natural gas extraction in the past two decades. The continued monitoring of streams over their lifetime as extraction sites is pivotal to understanding the effects of fracking on local waterways and their ability to provide for wildlife and human use. Here, using multiple indices of biotic integrity (IBI), I perform analyses of fish and macroinvertebrate communities as well as water chemistry on two streams, Bates Fork (with shale wells) and Fonner Run (without), as part of a follow-up to work performed there from 2010-2012. Fish …
Demography Of Alligator Snapping Turtles (Macrochelys Temminckii) Along A Fishing Pressure Gradient, Luke T. Micek
Demography Of Alligator Snapping Turtles (Macrochelys Temminckii) Along A Fishing Pressure Gradient, Luke T. Micek
Electronic Theses and Dissertations
Passive fishing gear is a threat to the alligator snapping turtle (Macrochelys temminckii). The spatio-temporal persistence of this threat and its impacts on M. temminckii populations has not been quantified. I quantified the density of passive fishing gear and the demographic parameters of M. temminckii along a fishing pressure gradient in East Texas streams. Most gear was abandoned and illegally deployed, with densities varying seasonally. Detectability of passive fishing gear declined with increasing gear age, water depth, and volume, but increased with increasing precipitation. Macrochelys temminckii catch per unit effort, abundance, and survival was lower at sites with …
The Impact Of Maternal Age On The Expression Of Transgenerational Plasticity In Daphnia Pulicaria, Calvin Nguyen
The Impact Of Maternal Age On The Expression Of Transgenerational Plasticity In Daphnia Pulicaria, Calvin Nguyen
2025 Spring Honors Capstone Projects - Archive
Transgenerational plasticity refers to heritable, non-genetic changes in phenotype that persist across multiple generations and can enhance offspring survivability in variable environments. In Daphnia, increasing maternal age has been associated with maladaptive plasticity. To investigate this relationship, six clones were collected from two Wisconsin lakes and acclimated to laboratory conditions through a common garden rearing process. For each clone, ten replicates were generated and evenly divided between young (clutches 2–4) and old (clutches 5–8) maternal age groups. Offspring were exposed to three dietary treatments for three experimental generations: one fed only green algae, one fed only cyanobacteria (a nutritionally …
Epidemiological Inferences Of The Impacts Of Winter Ticks On Moose Health, Krishna S. Woerheide
Epidemiological Inferences Of The Impacts Of Winter Ticks On Moose Health, Krishna S. Woerheide
Department of Entomology: Dissertations, Theses, and Student Research
The North American Moose (mooz in Anishinaabemowin, Ojibwe language, Alces alces), a culturally significant subsistence species for the Anishinaabe people, faces population decline due to calf predation, pathogen transmission, and parasitism by the winter tick (Dermacentor albipictus), all exacerbated by climate change. This study explores the impact of winter tick infestations on moose health, with a focus on natural mineral seeps as potential transmission hotspots in moose habitats within the Grand Portage Indian Reservation (Gichi Onigaming), on Isle Royale National Park (Minong), and within the 1854 Ceded Territory (greater northeastern Minnesota) - ancestral and present homelands of …

Spatial Ecology And Predator–Prey Interactions Of Mountain Lions In California's San Francisco North Bay, Jacob A. Harvey
School of Natural Resources: Dissertations, Theses, and Student Research
Understanding spatial ecology and predator-prey interactions are central to wildlife ecology and conservation. We tracked mountain lions with GPS telemetry to evaluate space use, predator-prey interactions, and resource selection in California’s San Francisco North Bay, USA. In Chapter 1, we evaluated the influence of human disturbance on home range size, prey composition, and kill rates on black-tailed deer (Odocoileus hemionus columbianus) across an urban-rural gradient. Both males and females increased home range size with increasing development at low to moderate levels of development, but female home range size stabilized across greater proportions of development while male home range …
A Population Study Of The Freshwater Turtles Of The Recently Expanded Lake Hydaway In Campbell County, Virginia, Joshua Sorenson
A Population Study Of The Freshwater Turtles Of The Recently Expanded Lake Hydaway In Campbell County, Virginia, Joshua Sorenson
Senior Honors Theses
Freshwater turtles are an important part of the ecological systems in central Virginia. At the recently expanded Lake Hydaway, there are several turtle species for which their population characteristics were unknown, especially the prolific Eastern Painted Turtle (Chrysemys picta picta) and Red-bellied Cooter (Pseudemys rubriventris). For five weeks, the lake was surveyed for turtles using hoop nets, and the turtles were marked and measured. Population characteristics such as carapace length and sex ratio for the Eastern Painted Turtle and Red-bellied Cooter were calculated, as well as population estimates for those two species. The Red-eared Slider ( …

In the early 1980s Diadema antillarum, or the long-spined urchin, was hit by a catastrophic mass mortality event across the western Atlantic and Gulf of Mexico, inclusive of the Florida Keys. The cause of this die-off event was likely triggered by a pathogen or environmental stressor that decimated native populations by up to 98%. The species has not yet fully recovered and is struggling with recruitment success which is why it may benefit from an ex-situ recovery program. In this study, I used single nucleotide polymorphisms (SNPs) to identify genetic variation and analyze parentage in a captive population of …

Assessing Intra-Seasonal Changes In Summer Elk Diet Composition, Ava E. Window
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Elk (Cervus canadensis) require adequate forage to fulfill their seasonal nutritional requirements. Elk undergo their highest nutritional demands during summer to support critical life functions such as late gestation, lactation, and juvenile growth. However, variations in plant phenology significantly influence the quality and quantity of forage available to elk during the summer season. As summer advances and plant communities mature, forage quality often declines, leading to a landscape that imposes greater nutritional constraints on elk. As a result, prior research on elk foraging habits has primarily focused on late summer. This has led to limited knowledge surrounding the …

We conducted surveys for the Cedar Keys Mole Skink, Plestiodon egregius insularis (Mount), during 1989– 1999 and 2015–2024, examined museum vouchers, and compiled personal observations from others to determine the status and distribution of this subspecies, which has the smallest geographic distribution of the five subspecies and is being considered for federal listing. We observed Cedar Keys Mole Skinks on Airstrip Island, Atsena Otie, Cedar Point, Deer Island, North Key, Scale Key, Seahorse Key, Snake Key, and possibly Dog Island. We have anecdotal reports of Mole Skinks on Way Key, which contains the most potential habitat and is the main …
