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 …

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 …

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 …

“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 …

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 …

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?,

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 …

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 …
