Data To Accompany 'Diving Behavior In Semi-Aquatic Anolis Lizards Results In Heat Loss With Sex-Specific Cooling Tolerance', Alexandra M. Martin, Lindsey Swierk

Biological Sciences Faculty Scholarship

Males and females often differ in use of antipredator behaviors, particularly when antipredator behavior comes at the cost of missed mating opportunities or territory defense. When using thermally suboptimal refugia, ectotherms are especially vulnerable to these costs, as their performance is linked to body temperature. To flee from predators, semi-aquatic Anolis lizards dive underwater for long periods and rebreathe from a bubble of air. We hypothesized that using aquatic refugia would result in thermal loss, that dive duration would be influenced by sex, and that oxygen consumption when diving would help explain sex differences. We tested these hypotheses by measuring …

Assessing Forest Features And Nocturnal Flying Insect Diversity As Predictors Of Eastern Whip-Poor-Will Occupancy In Foraging Habitat, Clark D. Alexander

Graduate Theses, Dissertations, and Problem Reports

Eastern whip-poor-will (Antrostomus vociferus), an insectivorous caprimulgid, have seen an approximate 2.76% annual population decrease since the 1960s, with their breeding and foraging ecology largely unknown due to their nocturnal and cryptic behavior. I conducted research to assess abiotic and biotic variables correlated with detection, and occupancy probability, and prey species diversity on ~104,000 hectares of forest in West Virginia, owned by the private timber company Weyerhaeuser. Previous literature indicates that Eastern whip-poor-will, and their prey, require ephemeral habitat such as recently cleared and early successional forests, like those historically created by forest fires, wind shears, hurricanes, and …

Responses Of Elk To Mangement Actions And Hunter Access In The Northern Sapphire Mountains, Montana, Usa, Peter O. Mumford

Graduate Student Theses, Dissertations, & Professional Papers

Chapter 1

Regulation of rifle hunting of adult female elk is the main tool wildlife managers use to manage the abundance of elk (Cervus canadensis) in the western United States. However, elk are increasingly located in areas where hunting access is restricted during rifle-hunting season, decreasing the ability of managers to reduce elk abundance through hunter harvest. Management actions that restricted hunter access in a 26 km2 area and closed 62 kms of predominantly 2-wheel motorized routes occurred in the northern Sapphire Mountains, Montana, USA. We collected data on elk locations before and two years after the management actions and …

Context-Dependency And Sex-Specificity Of Dispersal Syndromes, Allyssa Kilanowski

Theses and Dissertations--Biology

For populations in landscapes with increasingly heterogeneous and fragmented habitat patches (e.g., metapopulations), dispersal is an important behavior that leads to gene flow and connectivity among isolated patches. Because dispersal is a complex process, there are many traits involved. When suites of morphological, behavioral, physiological, and life-history traits covary with dispersal (e.g., a dispersal syndrome), the correlated traits can assist dispersing individuals through the complex process. Furthermore, once dispersal is completed, the correlated traits can influence the fitness of those dispersed individuals. Dispersal syndromes will likely interact with the local environment to produce ecological and evolutionary feedbacks on the metapopulation. …

Multilevel Phenotypic Integration Of Metabolism And Behavior In House Sparrows And Mice, Tim Salzman

Theses and Dissertations--Biology

Patterns of multilevel variation in behavior, both within and among individuals, raise challenging questions about underlying mechanisms and the selective pressures acting on them. One intriguing hypothesis is that physiology shows parallel multilevel variation, and so might represent a latent trait that integrates multilevel behavioral responses. For example, foraging acquires the fuel needed to maintain metabolism, and in turn, an individual’s metabolism affects expression of foraging, and other, behaviors. Metabolism and behavior thus might coevolve to become integrated traits. Despite the appeal of this hypothesis, numerous investigations into the link between metabolism and behavior have yielded largely equivocal results.

Variation In Behavioral Strategies For Coping With Environmental Uncertainty, Allison Mclaughlin

Theses and Dissertations--Biology

My dissertation investigates how animals behaviorally respond to environmental change, especially when there is limited information about that change. Uncertainty about the environment comes in various forms, including food resources which vary unpredictably and novel cues which present an unknown level of potential risk or benefit. Various behavioral strategies help animals cope with such uncertainty. Tactics to manage unpredictable variation in food include gathering information to reduce uncertainty (sampling) and strategically adjusting preference or aversion to variation in resources (variance-sensitivity). To manage the uncertainty of a novel cue, animals may generalize their previous experience with similar cues, or they may …

Habituated, Tolerant, Or Salt-Conditioned Mountain Goats And Human Safety, Richard B. Harris, Kurt Aluzas, Laura Balyx, Jami Belt, Joel Berger, Mark Biel, Tonya Chilton-Radandt, Steeve D. Côté, Julie Cunningham, Adam Ford, Patti Happe, Chad P. Lehman, Kim Poole, Clifford G. Rice, Kirk Safford, Wesley Sarmento, Laura Wolf

Human–Wildlife Interactions

Interactions between humans and wildlife include a number of consumptive and non-consumptive forms. In some cases, the increased demand for wildlife viewing can precipitate new human–wildlife conflicts. Mountain goats (Oreamnos americanus; goats) are native to a number of North American mountain ranges from southeastern Alaska to southwestern Montana, USA. Goat habitat typically consists of steep terrain and cold weather habitats, which has left them particularly vulnerable to climate change. Their alpine environments also make them vulnerable to disturbance by aircraft and land-based motorized human activity. We reviewed and characterized situations in which goats in close proximity to humans …

Effects Of Aging On The Reproductive Success Of Female Saltmarsh Sparrows (Ammospiza Caudacutus) In Maine And New Hampshire, Isabella Rose Collamati

Honors Theses and Capstones

The saltmarsh sparrow (Ammospiza caudacutus) is a ground-nesting specialist in coastal salt marshes of the Northeast. Rising sea-levels increase the loss of offspring due to tidal flooding, reducing nest success and resulting in a sharp population decline. In other avian species, age has been shown to affect nest success through altering fertility, behavior, and the number of young produced, favoring older individuals. I investigated age effects on nest success of female saltmarsh sparrows using nest monitoring data collected at four sites of a long-term demographic monitoring project: Chapman's Landing (Stratham, NH), Eldridge Marsh (Wells, ME), Popham Beach (Phippsburg, …

Can The Food Preparation Hypothesis Account For Anting Behavior In Birds?, Ella Brady

2023 REYES Proceedings

This report discusses the food preparation hypothesis, one of several proposed hypotheses to explain anting behavior in birds. A brief review of the theory’s history and development, as well as an assessment of evidence for and against such a function of anting, is provided. Although there are indeed experimental data supporting food preparation as the purpose of anting behavior, there is also conflicting evidence which complicates the theory. Ultimately, it is suggested that food preparation is a secondary function of anting – a pleasant but latent “side effect” achieved alongside the behavior’s primary purpose, which is still unknown.

Hypotheses Related To Anting By Birds, Helena Flores

2023 REYES Proceedings

“Anting” is a widespread behavior among bird species and mammals. Due to the various characteristics of this behavior, numerous hypotheses have been proposed to explain it. This behavior can be classified as “active”, in which birds take a bill full of ants and rub them into their feathers, or “passive” when birds let ants wander through their plumage. The hypotheses state that anting may be performed as an (1) antiparasitic behavior, for (2) feather grooming, as a way of (3) food preparation or to (4) decrease skin irritation during molt, even as a (5) sensory stimulation tool. This review compiles …

Habitat Associations And Fine-Scale Movements Of The Red-Spotted Toad (Anaxyrus Punctatus) In Kansas And The Efficacy Of Remote Telemetry For Monitoring Small-Scale Movements, Elisabeth Russell

Master's Theses

As climate change progresses, arid-adapted anurans might be particularly susceptible to population declines because of their reliance on ephemeral pools for successful reproduction. Because arid-adapted anurans are difficult to study due to short active seasons and cryptic lifestyles, little is known about their habitat preferences. One such arid-adapted species is the Red-Spotted Toad (Anaxyrus punctatus; RST), a Kansas Species in Need of Conservation. Since this designation in 1987, little research has been conducted to understand their conservation needs. During the summers of 2021 and 2022, RST surveys were conducted both near areas where the species has historically been …

Human–Black Bear Interactions And Public Attitudinal Changes In An Urban Ordinance Zone, Mark A. Barrett, Sarah E. Barrett, David J. Telesco, Michael A. Orlando

Human–Wildlife Interactions

Human–bear (Ursus spp.) interactions (HBI) commonly occur in residential areas throughout North America. Negative HBI can be alleviated by using bear-resistant garbage cans (BRC) and by securing other bear attractants (e.g., bird feeders). Since the early 2000s, human and Florida black bear (U. americanus floridanus) densities have increased substantially throughout Florida, USA, concurrently producing an increase in HBI. In central Florida, an area with high densities of humans and black bears, we surveyed 2 neighborhoods that occurred in an urban ordinance zone established in 2016 that required residents to secure anthropogenic food sources. Residents were supplied with …

Out Of The Frying Pan And Into The Fire: How Hunting Affects The Diel Activity Patterns Of Ungulates In Lubrecht Experimental Forest, Shawn M. Parsons

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Predator-prey dynamics shape diel activity patterns of large mammals. The avoidance of predation risk by prey in both space and time can affect predator-prey overlap and reduce risk of mortality. Here, I examined if rifle hunting affected the diel activity patterns of ungulates and their primary predator, pumas, in Lubrecht Experimental Forest, Montana. I deployed 30 infrared wildlife remote cameras across 29 sites using a stratified random design over three months before, during, and after the Fall 2022 Montana rifle hunting season. This project was also part of the Snapshot USA 2022 initiative. Using timestamps from these photos, daily activity …

Finding An Accurate Method To Measure Pollinator Visitation Rates, Claire Struhsaker

Williams Honors College, Honors Research Projects

Pollinator visitation rates are a helpful way to monitor the health of ecosystems; however, there lacks a standardized method for obtaining these rates. The pollinator visitation rates for five plant species were collected and the relationship between the standard error of these rates and the time interval was determined. Monarda, Echinacea purpurea, Pycnanthemum muticum, and Baptisia alba all exhibit more accurate pollinator visitation rates as the time interval increased. Trifolium repens exhibited less accurate pollinator visitation rates as the time interval increased.

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer

MSU Graduate Theses

The Black-capped chickadee (Poecile atricapillus) and Carolina chickadee (P. carolinensis) are North American songbird species that hybridize in a narrow contact zone stretching latitudinally from New Jersey to Kansas, USA. The association between genetic ancestry and song type in this hybrid zone has been studied independently several times and found to be minimal or absent, likely due to the influence of cultural transmission on learned song in the oscine passerine clade to which the chickadees belong. Despite this, the song of both species remains remarkably distinct in allopatry, suggesting a genetic constraint on certain qualities of …

Between Choice And Compulsion: An Examination And Critique Of The Evolution Of 'Original Sin', Matthew James Wynn

MSU Graduate Theses

“Why are we the way that we are?” is one of the hardest questions to answer because it requires grasping the origin of human beings. This has left philosophers and theologians in century-long debates on forming a “cosmogony of ontology” (i.e., how the origin of the universe informs the human condition). The concept, “original sin” was developed by a North African theologian named Augustine (354 – 430 CE). Augustine’s reading of Genesis 3, and inaccurate translation of Romans 5:12, taught that a person is born morally culpable for a fault antecedent to their existence. This way of thinking about the …

Activity Patterns Of The Critically Endangered Central American River Turtle (Dermatemys Mawii), Cora Dyslin

MSU Graduate Theses

The Central American River Turtle (Dermatemys mawii) is native to southern Mexico, eastern Guatemala, and Belize and is primarily restricted to watersheds that drain into the Gulf of Mexico and Caribbean Sea. Hunting, both for personal consumption and market meat, has been the primary driver of declines, and the species is now classified as critically endangered. Results from past studies that have used netting and visual surveys to detect D. mawii suggest that the species is chiefly nocturnal. However, it is unclear to what extent the perception of nocturnality has been biased by the timing of survey efforts …
