Repeatability And Distribution Of Behavior Types Over Time And Across Populations In Free-Ranging Adult And Juvenile Ornate Box Turtles (Terrapene Ornata), Abigail Trautman

2023 Midwest Ecology & Evolution Conference

As studies continue to investigate inter-individual variation, it is becoming increasingly evident that individual animals have their own unique behavior type (personality; repeatable behaviors over time and context) that persists throughout their life. Behavior is simply different forms of motion, and a behavior type influences which motions (behaviors) are most likely to be on display. Behavioral types can influence resource acquisition, predation risk, and mating opportunities and thus can directly influence the fitness of any given individual. In this study, we examine the behavior types of free-ranging adult ornate box turtles (Terrapene ornata), including their repeatability and variation …

Relationship Between Learning And Bt In Ornate Box Turtles (Terrapene Ornata), Brianna M. Wilson

2023 Midwest Ecology & Evolution Conference

Cognition is important to the individual animal and can help determine its role and impact on its ecological niche. Variation in cognition may influence the way animals interact with their environment and their performance in certain behaviors such as resource acquisition, range philopatry, and navigation. The question has been raised as to whether cognitive styles such as fast-slow or speed-accuracy types share a relationship with behavioral type. Animal personality (behavioral type) is made up of five axes: boldness, aggression, sociality, activity, and exploration. In this study, we investigate learning in a western Nebraska population of ornate box turtles (Terrapene …

Variation In Synthetic Floral Microbiome Composition Is Largely Ignored By Foraging Bumblebees, Nevin P. Cullen

2023 Midwest Ecology & Evolution Conference

Most flowers are occupied by diverse communities of microbes, which can alter floral attractiveness to key pollinators and floral fitness by interacting with floral traits. Different species of flower often acquire unique communities of microbes. Consequently, pollinators are frequently forced to choose between two flowers with distinct floral microbiomes while foraging. However, it is currently unknown whether pollinators have an inherent preference for flowers containing one floral microbiome over another, and whether microbial preference is modified by variation in floral traits. We investigated this knowledge gap using distinct bacteria and yeasts cultured from a nickel-hyperaccumulating plant and its non-accumulating relative. …

An Optimal Patch Use Model For Nitrogen Foraging In Arbuscular Mycorrhizal Fungi, Xin Lin

2023 Midwest Ecology & Evolution Conference

Optimal Foraging Theory has been widely used to study animal foraging behaviors, but has seldom been applied to symbiotic microbes like arbuscular mycorrhizal (AM) fungi. To date we know little about how AM fungi make decisions to forage in different nutrient patches. To help address this gap we here apply Optimal Foraging Theory to understand how AM fungi forage for nitrogen. We focus on nitrogen because AM fungi need more nitrogen than their plant hosts and soil nitrogen availability can shift the relationship between AM fungi and their hosts from mutualism to parasitism. We present a stochastic dynamic programming model …

Coyote Occupancy And Movement In Hanover County, Virginia, Richard S. Groover

Virginia Journal of Science

Although the coyote (Canis latrans) is native to North America, we have limited understanding of its presence in Virginia. Coyote range expansion is linked to anthropogenic factors, including habitat fragmentation and the extirpation of apex predators. Information on coyote adaptations to Virginia habitats is scarce, and eastern coyotes may have unique adaptations for colonizing an area. Anecdotal evidence suggests that coyotes are abundant in Hanover County (north of Richmond, VA), but this has not been confirmed. This study was conducted over an 18-month period with multiple survey sites throughout Hanover County, each equipped with game camera stations and …

A Survey Of Captive Wild And Exotic Animal Training Programs In The Eastern United States, Savannah Atchison

Senior Honors Theses

Methods of positive reinforcement as a successful means for animal training are the result of many years of research into operant conditioning and learning. However, current literature is unclear on the extent to which these methods are utilized in captive wild and exotic animal populations in the United States. Through phone interviews with animal trainers employed at zoos and wildlife rehabilitation centers in the eastern United States, the author determined that these facilities are currently utilizing positive reinforcement training methods which are proving to be a great benefit for all parties involved. They are enabling a variety of voluntary health …

Heterospecific Anural Eavesdropping Cues, Lucia C. Maldonado, Hayley Lunn, Max Sprute, Andrew Wang, Ripley Conklin, Nolan Gentile, Conor Kramer, Lee Kats

Seaver College Research And Scholarly Achievement Symposium

The ability to communicate within species is a trait utilized by every organism. Using cues conspecifically creates a better chance of survival for other members of the species and increases fitness overall. However, using cues heterospecifically also poses a great advantage as animals can eavesdrop on cues released by another species. Previous studies have recorded that eavesdropping is beneficial to prey species, such as squirrels reacting to bird calls and tadpoles reacting to visual and chemical cues to avoid predation. We asked how one local and one exotic species of frog would respond to cues emitted by another local species …

Movement, Behavior, And Trophic Ecology Of A Pelagic Predator Guild In The Eastern Tropical Pacific Ocean, Ryan Keith Logan

All HCAS Student Capstones, Theses, and Dissertations

Pelagic apex predators exert strong influences on ecological communities, and often support valuable commercial or recreational fisheries worldwide. Yet, due to their rarity and pelagic lifestyle, many species, such as billfishes, have proven particularly difficult to study at resolutions necessary to define dynamics of recovery from fishery interaction, physical interaction with environmental features and prey exploitation, and competitive interactions among other billfish predators. This leads to a paucity of knowledge on billfish ecology and habitat use, and hinders management efforts. With the ever-improving and miniaturization of technology and oceanographic datasets, the ability to define and quantify these interactions of fish …

Prairie Dogs, Gary Witmer, Jon Grant, Kendra Cross

Wildlife Damage Management Technical Series

Prairie dogs (Cynomys spp.) occur throughout the prairie states of middle North America from Mexico northward into Canada. They occupy a variety of habitats from prairies to high mountain valleys and sage brush-dominated deserts. The most common species is the black-tailed prairie dog (Cynomys ludovicianus; Figure 1). Prairie dogs are considered a “keystone species.” They provide habitat for many other native, grassland species. Prairie dogs live in colonies or “towns” that can span hundreds to thousands of acres. Depending on the species, their presence is evident by their burrow system. Despite the many ecosystem benefits prairie dogs provide by modifying …

Why The Delay In Recognizing Terrestrial Obligate Cave Species In The Tropics?, Francis G. Howarth

International Journal of Speleology

“Nothing could possibly live there!” They believed. Indeed, until recently, few specialized cave- adapted animals were known from volcanic, tropical, or oceanic island caves, and plausible theories had been put forward to explain their absence. But assume nothing in science! One must illuminate, explore, and survey habitats before declaring them barren. Our understanding of cave biology changed dramatically about 50 years ago following the serendipitous discovery of cave-adapted terrestrial arthropods in Brazil and on the young oceanic islands of the Galápagos and Hawai‘i. These discoveries and subsequent studies on the evolutionary ecology of cave animals have revealed a remarkable hidden …

Ambient Electromagnetic Radiation As A Predictor Of Honey Bee (Apis Mellifera) Traffic In Linear And Non-Linear Regression: Numerical Stability, Physical Time And Energy Efficiency, Vladimir Kulyukin, Daniel Coster, Anastasiia Tkachenko, Daniel Hornberger, Aleksey V. Kulyukin

Computer Science Faculty and Staff Publications

Since bee traffic is a contributing factor to hive health and electromagnetic radiation has a growing presence in the urban milieu, we investigate ambient electromagnetic radiation as a predictor of bee traffic in the hive’s vicinity in an urban environment. To that end, we built two multi-sensor stations and deployed them for four and a half months at a private apiary in Logan, Utah, U.S.A. to record ambient weather and electromagnetic radiation. We placed two non-invasive video loggers on two hives at the apiary to extract omnidirectional bee motion counts from videos. The time-aligned datasets were used to evaluate 200 …

Data To Accompany "Altered Heat-Avoidance Behavior Following Damage To The Extended Architecture Of Mexican Jumping Bean Moth Larvae (Cydia Saltitans)", Anna Purtell, Lindsey Swierk

Biological Sciences Faculty Scholarship

In response to physical damage, organisms must balance physical recovery with adaptive responses to other environmental stressors. Understanding how damage and repair influence adaptive responses to high environmental temperatures is of particular interest in light of global climate change. We investigate the impact of damage and subsequent repair on heat-avoidance behaviors in Cydia saltitans larvae inhabiting host seeds (Sebastiana pavoniana) as protective structures (together colloquially known as “Mexican jumping beans”). These larvae perform temperature-dependent “jumping” or “rolling” behaviors to escape extreme heat, which are crucial for larval survival in their native arid and hot subtropical dry forests. Due …

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 …

Surviving The Serenade: How Conflicting Natural And Sexual Selection Drove Rapid Diversification Of Mating Signals In An Insect, James H. Gallagher

Electronic Theses and Dissertations

Understanding how the early stages of sexual signal diversification proceed is of critical importance because the nature of these microevolutionary dynamics can directly shape species trajectories and macroevolutionary patterns. Unfortunately, studying signal diversification is challenging because signals involve complex interactions between behavioral, morphological, and physiological components, many of which can only be measured in real time. Here we had the opportunity to directly study this process with the recent increase in sexual signal variation in Hawaiian populations of the Pacific field cricket (Teleogryllus oceanicus). In Hawaii, male song attracts both female crickets and a deadly acoustically orienting parasitoid …

Using Art To Foster Creation Care And Advance Environmental Sustainability, Orion Wakeman, Dave Warners

Summer Research

Calvin University is on land that drains into the Plaster Creek watershed, which is known as the most contaminated watershed in West Michigan. Plaster Creek Stewards (PCS) is a local watershed group at Calvin University that uses native plantings and curb-cut rain gardens to address human impact to the watershed, including ten areas on Calvin’s campus. The restored habitats and rain gardens are unique features that still perceived by many as a challenge to traditional aesthetics. I embrace the intersection of arts and sciences to provide PCS and Calvin University with visually compelling resources for the public to learn about …

Do Channel Catfish Consume Zebra Mussels?, Casey M. Myers

Journal of Earth and Life Science

Channel catfish Ictalurus punctatus are a generalized opportunistic feeder with a wide range of diet compositions. In the Midwest, zebra mussels Dreissena polymorpha have quickly spread, causing large effects on aquatic ecosystems structures and functions. Channel catfish are known to consume native mollusks, however, little research has been done on the potential predation of zebra mussels by channel catfish. Therefore, the objective of this study was to analyze channel catfish diets to determine if zebra mussels are consumed. The channel catfish were obtained from the Sauk River chain of lakes between the dates of 14 June and 28 July 2023. …

The Effects Of Chemical Secretions By Millipedes On Anting Behaviour In Birds And Other Animals, Theo Fraser

2023 REYES Proceedings

Birds perform a behavior known as anting in which they actively rub ants in their feathers or allow ants to crawl over their bodies. Several hypotheses have been proposed to explain this behavior, but no one hypothesis can account for all cases of anting that have been observed. Anting behavior has been recorded in species other than birds including primates, and substances other than ants such as millipedes may be used. This paper explores the use of millipedes in anting by birds, capuchin monkeys and lemurs. The three hypotheses supported by these studies include 1) anting serves as food preparation …

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 …

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

Graduate Theses/Dissertations

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 …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Foraging Behavior In The Eastern Subterranean Termite, Reticulitermes Flavipes (Kollar) (Isoptera: Rhinotermitidae), Anugerah Fajar

Theses and Dissertations--Entomology

Foraging is essential for survival, but it can be unpredictably dangerous due to organismal interactions like competition and predation to various environmental factors. Animals have come up with strategies to safeguard foraging. Social insects, with their elaborate division of labor, have developed sophisticated systems of foraging task allocation that allow them to capitalize resources beyond their competitors. In this thesis, I delve into the subjects of foraging behavior, allocation strategies, and the genetic basis of foraging in the eastern subterranean termite, Reticulitermes flavipes, the most widely distributed termite species in North America and one of the most economically important …

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, …

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 or Doctor of Nursing Practice

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 …

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 …

Understanding The Effects Of Age, Environmental Conditions, And Placement On Cockroach Gel Bait Performance, Isabelle Lucero

Theses and Dissertations--Entomology

Cockroach baits are one of the most effective tools used for German cockroach (Blattella germanica L.) control. This is due in part to the number of cockroach baits on the market with various matrix compositions and active ingredients, aiding in the control of resistant (physiologically and behaviorally) cockroach populations through bait rotation. However, it remains unclear how cockroach gel baits perform over time and under different environmental conditions. Therefore, we aged six cockroach gel baits for varying times (24 hours, one month, three months, six months) and at three relative humidities (15%, 40%, and 80%), and tested their performance …

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

Graduate Theses/Dissertations

“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

Graduate Theses/Dissertations

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 …
