Response Of Various Body Parts Of House Flies, Musca Domestica, To Sucrose, Panchalie B. Gunathunga, Merveille Muyizere, Bethia H. King

Faculty Articles, Papers, and Other Scholarship

Insects use multiple body parts, not just their mouth, to taste. Whether a particular body part has a taste function can be determined by examining the morphology or electrophysiological response of its sensilla (sense organs) or by its behavioral response. The present study investigated taste response of each of the three pairs of tarsi, tibiae, femurs, as well as the antennae and wings, in house flies, Musca domestica L. (Diptera: Muscidae). This was done by measuring the proboscis extension response (PER), and in the case of the wings, also the grooming behavior. PER is a visible precursor to consumption. The …

Decoding The Plant Metabolome: A Metabolomics Approach To Guereza (Colobus Guereza) Feeding Ecology In Kibale National Park, Uganda, Emma Grace Thurau

Dissertations, Theses, and Capstone Projects

Plant metabolites, an elusive and diverse group of plant chemicals, represent a complex chemical interplay between plants and herbivores. Plants contain essential nutrients necessary for herbivore survival, yet herbivore consumption results in negative fitness consequences to a plant. This relationship has triggered a coevolutionary arms race in which plants have evolved chemical defenses to prevent herbivore consumption and herbivores, in response, have evolved their own counter-adaptations. This arms race has led to the diverse numbers of herbivores and plants observed today; therefore, these plant metabolites act as a signature of evolution through their influence on herbivore adaptations. Plant metabolites are …

Experimentally Testing A Mechanism Of Urban Adaptation: Are Wild Catbirds Able To Immediately Adjust Their Song In Response To Urban Noise?, Eriberto Osorio

Masters Theses, 2020-current

Anthropogenic noise is loud and low-frequency (low-pitch) sound with frequencies spanning from 1-2.5 kHz in frequency. In noisy urban areas, many birds sing songs with higher minimum frequencies, which can avoid the masking effects of anthropogenic noise. However, the mechanism for an individual to alter spectral aspects of bird song in real time to avoid the masking effect of urban noise is unknown. Immediate flexibility is the ability a bird may use to shifts their song frequency or amplitude in response to noise fluctuations in the environment. Some species that sing higher frequency songs in noisy habitats are not able …

Ghosts In Glass: Ghost Crabs (Ocypode Quadrata) As Judges Of Glass Sand For Coastal Restoration, Emily Parrish

Poster Presentations

Coastal erosion is heavily impacting coastal ecosystems across the Gulf. For instance, the state of Louisiana loses a football field worth of land every 100 minutes (Couvillion, 2017). The drastic loss of coastline highlights the dire need for restoration in the Northern Gulf Coast. An unexpected solution to this sediment loss may solve two major environmental issues at once by diverting millions of tons of glass waste from entering America’s landfills each year. By crushing glass to create sand and gravel for coastal restoration, we may generate a consistent and sustainable source of substrate. Our goal is to determine the …

The Effects Of Geographic Isolation And Anthropogenic Activity On The Social Behavior Of Caribbean Green Monkeys., Rose Amrhein

Electronic Theses and Dissertations

Green monkeys (Chlorocebus sabaeaus) arrived to the Caribbean with the Trans-Atlantic slave trade. Since then, they have experienced unique environments to those of their native ranges in West Africa. Additionally, recent taxonomic changes within the genus make previous knowledge about the species hard to determine to be accurate. In this dissertation, I both assess some of the effects the island environment may have had on monkey behavior as well as build on the understanding of their vocal communication across three islands: Barbados, St. Kitts, and St. Martin. In chapter one, I investigate how human activity in Barbados affects …

The Movement Ecology, Ranging Patterns, And Territoriality Of Azara’S Owl Monkeys (Aotus Azarae) In The Argentinean Chaco Forest, Jeremy D. Pustilnik

Master of Environmental Science Theses

Azara’s owl monkeys (Aotus azarae) are small, pair-living, socially monogamous primates that inhabit the Chaco Forest of South America. Their activity and life history patterns have been particularly well studied, however, their movement ecology and ranging patterns within their home ranges remains largely unknown. Herein I descriptively analyze these patterns with respect to time, space, ambient environment, and physical environment using spatial information on five owl monkey groups that were followed over the course of a year between 1998 and 1999 at a multi-decade-operating field site near Formosa, Argentina. Analysis of distance and speed moved during different diel …

Ghosts In Glass: Ghost Crabs As Judges Of Glass Sand For Coastal Restoration, Emily Parrish

Honors Theses

Over 60% of the Gulf of Mexico coastline is actively eroding, which has resulted in thousands of miles of lost coastline over the last 100 years. This drastic loss of coastal land highlights the dire need for coastal restoration across the entirety of the Gulf Coast. A vital aspect of restoring these eroded areas is replenishing eroded substrate, traditionally conducted through offshore dredging of substrates which comes with high economic and ecological costs. Recycled glass sand may be able to fill this role and reduce our reliance on dredging while lowering the amount of glass waste entering landfills each year. …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

Stereotypic Behaviors And Physiological Indicators Of Stress Occur In Horses With Restricted Durations Of Turnout, Elizabeth E. Rodgers

Department of Animal Science: Dissertations, Theses, and Student Research

The confinement of horses to stalls with limited or no turnout time restricts their natural roaming behaviors, which potentially increases stress and behavioral stereotypies. This study investigated the impact of turnout duration on behavioral and physiological stress indicators in healthy horses. Adult horses (n = 11) were enrolled in a 3 treatment (0-, 15-, and 60-minute turnout/day) Latin square design, including 3 12 d experimental periods over 6 weeks. Horses were acclimated to turnout (24.38 x 64.01m indoor arena) and stalls (2.74 x 4.87m - 3.66 x 3.66m) stalls prior to data collection on day 1. Experienced handlers managed …

Female Acceptance Of Mates Is Consistent Across Different Sex Ratios And Male Proximities In Wood Frog (Rana Sylvatica) Breeding Aggregations, Alia Kabbaj, Laura Bousaid, Gabriella Lowney, Lindsey Swierk

Binghamton University Undergraduate Journal

Sexual selection plays a crucial role in shaping reproductive strategies. We investigated the influence of sex ratio and male proximity on female acceptance of mates in wood frogs (Rana sylvatica). We hypothesized that females at a more even sex ratio would exhibit higher acceptance of males due to reduced male competition when compared to females at a more male-skewed sex ratio. Using digital video analysis of mating trials (n = 39), we quantified male proximity to females and female acceptance of males at two sex ratios – 1:4 (F:M) and 1:7. Males at a 1:4 sex ratio maintained …

Designing An Optimal Thermal Preference Arena For Southern Cricket Frog (Acris Gryllus) Juveniles, Eleanor E. Briggs, David M. Phillips Jr.

Honors Theses

Climate change has been altering ecosystems across the world at a substantial rate, disrupting the delicate ecophysiological relationships between ecosystems and the organisms that live in them. Ectotherms, such as amphibians, rely on external temperatures to behaviorally thermoregulate, making it especially imperative to study their thermal biology. Thermal preference, which assesses the environmental temperature an organism would seek out in the absence of external stimuli, provides valuable information about an amphibian’s thermal biology and can be used to predict the effects of climate change on a species or population. A commonly used method to measure thermal preference is an arena …

How Bats View Their Flowers: Exploring The Use Of Visual Floral Cues By Nectarivorous Neotropical Bats, Lindsey R. Dennison

Theses

Neotropical nectar bats in cloud forest ecosystems must navigate and forage in dark, complex landscapes containing an incredible diversity of flowering plants. Despite these challenges, nectar bats are extremely successful at exploiting nectar resources from plants. Much of the sensory ecology behind these bat-plant interactions has been investigated and we know from previous studies that echolocation and olfaction are critical sensory modalities to nectar bats. Echo-acoustically conspicuous floral and vegetative structures as well as sulfur-containing volatile compounds function as signals, allowing bats to sense plants. However, not all plants exhibit conspicuous echo-acoustic and/or olfactory characteristics. Furthermore, many neotropical bat-pollinated plants …

More Choosy For Minor Foods: Diet, Seasonality And Food Selection In Sympatric Frugivorous And Folivorous Lemurs, Mitchell Irwin, Vololonirina Rahalinarivo, Bruno Ramorasata, Jean-Luc Raharison, Jean-Freddy Ranaivoarisoa, Chloé Gherardi, Jessica Rothman

Faculty Articles, Papers, and Other Scholarship

Despite traditional dietary categories common in primatology (folivore, frugivore, insectivore), most primates use one or more food types beyond their primary one. Among lemurs, folivores tend to have a complicated, long gastrointestinal tract with an enlarged cecum, shearing teeth, and microbiome adaptations to foliage, while frugivores have simple teeth and guts and fast gut passage. Yet frugivores often eat some leaves, and folivores eat some fruit, and little is known about the selection rules they follow within each food type. We quantified diet and food chemistry for two sympatric rainforest lemurs: a cathemeral frugivore (brown lemur, Eulemur fulvus) and a …

Transcriptional Profiles Reveal Physiological Mechanisms For Compensation During A Simulated Marine Heatwave In Yellowtail Kingfish (Seriola Lalandi), Sharon E. Hook, Ryan J. Farr, Jenny Su, Alistair J. Hobday, Catherine Wingate, Lindsey Woolley, Luke Pilmer

Fisheries Research Articles

Background

Changing ocean temperatures are already causing declines in populations of marine organisms. Predicting the capacity of organisms to adjust to the pressures posed by climate change is a topic of much current research effort, particularly for species we farm or harvest. To explore one measure of phenotypic plasticity, the physiological compensations in response to heat stress as might be experienced in a marine heatwave, we exposed Yellowtail Kingfish (Seriola lalandi) to sublethal heat stress, and used the transcriptome in gill and muscle, benchmarked against heat shock proteins and oxidative stress indicators, to characterise the acute heat stress …

Ecology Of Ixodes Scapularis Say: Experimental And Observational Studies With Social Perspectives On Ticks And Tick-Borne Diseases, Kaitlin M. Mcdonald

Dartmouth College Ph.D Dissertations

Tick-borne diseases are a growing concern globally. Understanding the factors that influence tick ecology and people’s understanding of that ecology is crucial for developing effective tick management and disease prevention strategies. In this work, I investigated fundamental questions about the ecology of a primary vector of medically important pathogens in the United States, the blacklegged tick Ixodes scapularis Say, and identified common misconceptions about ticks and tick-borne diseases on social media. First, I examined the effects of temperature and moisture stress on the movement of adult female I. scapularis in laboratory experiments. Using a Drosophila Activity Monitor, ticks were exposed …

The Effect Of Temperature And Vegetative Substrate On The Short-Distance Dispersal Behavior Of An Invasive Weevil (Coleoptera: Curculionidae) To A Protected Dune Thistle, Alyssa S. Hakes, Tina Czaplinska, Monica Paniagua-Montoya

The Great Lakes Entomologist

The invasion of a seed-eating weevil, Larinus carlinae (Olivier, 1807) poses a threat to the persistence of native Pitcher's thistle (Cirsium pitcheri), a federally-threatened plant in sand dune communities of the western Great Lakes. At Whitefish Dunes (Sturgeon Bay, WI. USA), seed predation by weevils is higher for thistles surrounded by native marram grass (Ammophila breviligulata) than for those located in sandy habitats. In this study, we observed how the local abiotic and biotic environment affects the short-distance dispersal behavior of L. carlinae. Weevils were captured on site and individually released on the sand approximately …

Offal Wildlife Watching: Connecting Hunters, Wildlife Researchers, And The Public Through Participatory Science, Ellen M. Candler, Grace Milanowski, Amy Rager, Joseph K. Bump

Journal of Extension

Offal Wildlife Watching is a participatory science project that engages deer hunters in wildlife research. The goal of the project is to better understand the ecology of scavenger species that visit deer gut piles across Minnesota. We asked hunters to deploy remote cameras at white-tailed deer gut piles that resulted from their freshly killed deer. Thus far 117 hunters have contributed images and recorded at least 49 different scavenger species. This project is a natural fit in Extension programs and can easily be adapted to other hunted species, biomes, and locations.

Additional Geographic Records Of Dekay’S Brownsnake (Storeria Dekayi) In Nebraska, Including A Late Seasonal Observation And Likely Range Expansion, Lauren Bahe, Dan D. Fogell, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Dekay’s Brownsnake (Storeria dekayi) occurs across much of eastern North America, inhabiting diverse environments such as marshes, woodlands, woodland edges, and urban areas. In Nebraska, recent studies documented its presence beyond the extreme southeastern region of the state, indicating a potential range expansion to the west and north. Our study continues to update its distribution with four additional county records. Two counties, Franklin and Harlan, represent the farthest west observations for Dekay’s Brownsnake in the state, further indicating a likely westward expansion. An observation from 6 December 2023 also represents the latest seasonal observation in the state. Despite …

Social Networks And Behavioral Adaptation Of Serrano Horses In A Rewilding Initiative In Spain, Ashley Bruno

Theses and Dissertations

Rewilding is a conservation measure that involves actively relocating species or restricting human land use to improve ecosystem sustainability. However, critics raise concerns that rewilding privileges ecosystem function over endangered species. Due to a lack of monitoring around species’ relocations, uncertainty lies in ecological outcomes and psychological, social, cultural impacts on affected animals. For this project, we collaborated with the non-profit Rewilding Europe that sought to conserve Serrano horses (Equus caballus), an ancient and under-studied breed of Spanish horse by relocating 11 individuals to a protected site in Guadalajara, Spain in June 2022. Our research aimed to address …

Impact Of Nature-Based Tourism On Bird Vocalization Rate In The Bajo Del Tigre Reserve, Monteverde, Costa Rica, Abby K. Bressette, Adriana Arias Aguilar

Environmental Studies Publications

Nature-based tourism benefits economies, communities, and conservation initiatives, but it can also have unintended negative effects on wildlife. For birds, vocal communication is essential, yet it can be disrupted by anthropogenic noise. In this study, I used passive recording to examine how human visitation impacts the rate of bird vocalizations in the Bajo del Tigre Reserve in Monteverde, Costa Rica. Overall, bird vocalization rate was not affected by visitation (p > 0.05), but species-specific differences were found. Vocalizations of the lesser greenlet showed no significant change with visitation (p > 0.05). In contrast, the orange-billed nightingale-thrush exhibited a decrease in vocalization rates …

Ms Environmental Biology Capstone Project, Emily A. Patton

Regis University Student Publications (comprehensive collection)

This is a masters Thesis for MS in Environmental Biology containing four chapters including a literature review, grant proposal, journal manuscript, and stakeholders report on a current environmental issue. (1) Noise Pollution and Avian Communication in Urban Ecosystems: When the Natural World Struggles to Hear Itself. Urban noise masks essential bird vocalizations, which harms avian fitness. Most species are displaced, and those few urban birds which counteract this noise with song adaptations likely experience trade-offs. America's noise policy remains undeveloped, threatening the health of both humans and avian wildlife (2) Application of Noise Barrier Technology for the Restoration of Urban …

Learning In Nonleafcutting Fungus-Gardening Ants, Elizabeth D. Boshers

Biology Theses

Social complexity influences learning and other cognitive behaviors, but for insects, this influence is not well understood. Delayed rejection is an aversive learning behavior previously studied exclusively in leafcutting ant species, the most socially complex of the fungus-gardening ants. Fungus-gardening ants are unique in that they do not directly consume the material they forage, using it instead as substrate to cultivate a symbiotic fungus on which the ants are obligately dependent. Here, I attempt to induce delayed rejection in several fungus-gardening ant species that exhibit a range of social complexity, then compare the characteristics of delayed rejection behavior among species. …

Evaluating The Condition Of Age-0 Burbot In Relation To Diet, Cian Verbridge

Journal of Earth and Life Science

Burbot are becoming more and more popular for angling and aquaculture. However, populations have been declining across the world. Very little information is available about their early life and their interactions in the ecosystem due to challenges in sampling. Condition estimates and diet metrics were used to better understand the status of burbot in Lake Bemidji. Using backpack electrofishing, 45 young of the year burbot were collected. The lengths ranged from 86 to 146 mm and the wet weights ranged from 4.29 to 24.36 g. The stomach contents were removed and stored in ethanol for later analysis. The burbot were …

Size Of Age-0 Sander Vitreus Pre And Post Dreissena Polymorpha Infestation On Brainerd And Bemidji Area Lakes, Quady Bernu

Journal of Earth and Life Science

Walleye Sander vitreus is the Minnesota state fish and a vital predator fish in lake ecology. Zebra mussels, Dreissena polymorpha were first found in Minnesota inland lakes in the 1980’s. These mussels have had huge impacts on water clarity as well as phytoplankton and zooplankton population levels which affect how age-0 fish feed, especially a low light feeding predator fish like walleye. A study took place on age-0 walleye size and it supported the conclusion that age-0 walleye were negatively impacted by zebra mussels in Minnesota’s large lakes. The goals of this study were to determine how the size of …

The Evolution Of The Stress Response In The Trinidadian Killifish: Ecological Drivers And Maternal Mediation, Mikaela E. Feder

Biology Dissertations - Archive

Ecological variables can induce the stress response in organisms. Yet, few studies have tested for evolutionary shifts in stress responses across ecological gradients. In these studies, we used Trinidadian killifish found in sites with predators (high predation, HP) and sites where they are the only fish present (killifish only, KO). HP and KO populations differ in a suite of behavioral and life-history traits, making the Trinidadian killifish an excellent model to examine evolutionary physiology. My dissertation addresses the knowledge gap by examining: (1) how baseline cortisol differs in wild-caught Trinidadian killifish found in HP and KO sites, (2) the influence …

Use Of Public Information For Prospecting And Nest Site Selection By Western Bluebirds (Sialia Mexicana), Fatime Wadad Jomaa

Cal Poly Humboldt theses and projects

Public information that provides an estimate of reproductive success, in addition to information gained through direct environmental sampling, may provide an efficient way for individuals to assess future breeding site quality. I investigated the hypothesis that prospecting Western Bluebirds (Sialia mexicana) use post-breeding public information to select nest sites the following year across winegrape vineyards in Napa Valley. In late summer of 2023, I installed 200 nest boxes across 10 vineyards without prior box history. To simulate conspecific presence and successful breeding, boxes within 5 experimental vineyards were designated either full-treatment (boxes directly broadcasting adult song and nestling …

Activity, Movement, And Reproductive Patterns Of The Northern Giant Musk Turtle (Staurotypus Triporcatus) In Belize, Larissa Sage Saarel

Graduate Theses/Dissertations

The Northern Giant Musk Turtle (Staurotypus triporcatus), a near-threatened species native to southern Mexico, Guatemala, Belize, and western Honduras, faces multiple environmental challenges, yet its activity patterns, movement patterns, and reproductive biology remain poorly understood. This thesis investigates both seasonal activity and reproductive cycles of female S. triporcatus in Belize. To assess diel and seasonal activity, I tracked 12 female turtles and collected data using activity loggers. I also collected movement data through radio-telemetry and acoustic tracking methods. Results indicated that the species is primarily nocturnal, with increased activity during the wet season, particularly during flooding events. Turtles …
