Effects Of Maternal Disease History On Provisioning, Brooding, And Offspring Outcomes, Sakura Roberts
Biological Sciences Undergraduate Honors Theses
Disease within a population has the ability to shape the development, evolution, and general performance of a species. Pathogen exposure to hosts can influence their physiology and behavioral patterns to further shape offspring immunity. Parental conditions experienced by offspring during early development can benefit survival and fitness (e.g. increasing provisioning rates), as well as help deter against similar diseases experienced by parents. By testing if parental behavior changes can better prepare offspring outcomes for disease exposure, such as disease severity or duration of infection, we can see the beneficial impacts it has on disease dynamics and host-pathogen processes. Incubation temperature, …

Hippopotamus (Hippopotamus Amphibius) Aggressive Behaviors In The Retima Hippo Pool, Orangi River, Tanzania, Lydia Hoffman, Connor Veldman
Celebrating Scholarship and Creativity Day (2018-)
Hippopotamuses (Hippopotamus amphibius) are known to forage on land during the night and spend the daytime in shallow pools to thermoregulate and to protect their skin from UV radiation. Daily use of pools may lead to competition for space and facilitate aggressive interactions between hippopotamuses. In this study, we looked at the difference in occurrence of aggressive behavior in the morning and evening hours between hippopotamuses (hippos). Our hypothesis was that hippos will be more aggressive at different times of the day, and we predicted that the higher aggressive activity will be in the morning hours, as hippos …

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 …

Hide And Seek: An Exploration Of Antipredator And Predator Avoidance Mechanisms In Orthopodomyia Signifera In Response To Predation From Toxorhynchites Rutilus, Nathaniel Dahlberg
Master's Theses
There have been many observations of larval Orthopodomyia signifera coexisting with the predator Toxorhynchites rutilus. There are three hypotheses that could explain how Or. signifera resists predation from Tx. rutilus. The first hypothesis states that larvae adapt behavioral changes that limit predation. The second hypothesis states thoracic setae serve as a physical defense that prevents Tx. rutilus from grasping Or. signifera. The third hypothesis states Or. signifera possess a chemical defense indicated by aposematic coloration. To test the first hypothesis larval Or. signifera were exposed to conspecific and heterospecific predation cues and their behavior was observed. Both cues …

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 …

Testing For Relationships Between Animal Personality Traits, Activity Level And Voracity, And The Underlying Influence Of Body Size In The Dragonfly Predator, Epitheca Canis, Flynn Gorman
Senior Theses and Projects
Animal personality, defined as among-individual variation in behavior, is taxonomically widespread, but its ecological implications remain unclear. While associations between animal personality and ecological traits have been examined, methodological shortcomings, such as lack of repeated measurements, limit the insights these studies provide. Here, I measured the repeatability of activity level and feeding rate behaviors in the nymph stage of the dragonfly predator, Epitheca canis, taking 10 repeated measurements of each trait over a 10-week period. Moreover, I tested for a relationship between among-individual variation in activity level and feeding rate while accounting for the underlying influence of nymph body …

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 …

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 …

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 …

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.

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 …

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 …

Nicotiana glauca is a medicinal plant used by traditional healers as antibacterial, antifungal, antiviral and anti-inflammatory medicines. The leaves of N. glauca are very rich in indolic alkaloids which give it a larvicidal power which allows us to use it as a bio-insecticide.In the present study we were perfomed in the direct (mortality) and indirect (food attractiveness and pupation) toxic effects of the aqueous extract of N. glauca on the mortality and feeding behavior of the fruit fly Drosophila melanogaster. The treatment was administered to 2nd instar larvae (L2) and the mortality rate was monitored for 15 days. Similarly we …

Journal of Bioresource Management
We analyzed fluctuations in of small mammals’ biodiversity through the winter diet of the common genet Genetta genetta (Linnaeus, 1958), to deduce the predator - adopted strategy according to the habitat conditions in which it occurs, particularly in anthropogenic environments. The field sampling was conducted during the 2020 winter season, in two contrasting environments of the Edough mountain range: natural site (Ain Boukal), and anthropized site (Bouzizi landfill). The analysis of 30 collected excrements in each of the two sites, allowed us to identify different food categories including small mammals. The result shows that the common genet is an excellent …

Examining The Relationship Between Stomiiform Fish Morphology And Their Ecological Traits, Mikayla L. Twiss
All HCAS Student Capstones, Theses, and Dissertations
Trait-based ecology characterizes individuals’ functional attributes to better understand and predict their interactions with other species and their environments. Utilizing morphological traits to describe functional groups has helped group species with similar ecological niches that are not necessarily taxonomically related. Within the deep-pelagic fishes, the Order Stomiiformes exhibits high morphological and species diversity, and many species undertake diel vertical migration (DVM). While the morphology and behavior of stomiiform fishes have been extensively studied and described through taxonomic assessments, the connection between their form and function regarding their DVM types, morphotypes, and daytime depth distributions is not well known. Here, three …

Insect Availability And Parental Care Behavior In A Common Bird, Cole Bourque
Symposium of Student Scholars
Populations of aerially insectivorous birds are declining throughout North America. Urbanization may indirectly contribute to this decline through its negative effects on populations of insects, an important food source in insectivores' diets, where low insect availability may be especially challenging for birds during breeding. How fluctuations in insect populations impact various species at higher trophic levels is an important area of current study for future conservation biology. Here, we examine whether nestling provisioning, brooding and guarding behaviors in a breeding bird—the European starling (Sturnus vulgaris)—may be altered depending on the relative insect availability in the environment. We found …

Supplemental bird feeding is a widespread hobby throughout western culture. Although it brings joy to many people, bird feeding has been shown to have potentially negative effects on local bird populations and small mammalian species. To study the differences in local occurrence of native small mammalian species around bird feeders and in more distant settings, six camera traps were placed in a rural residential area in Putnam County, Georgia. Three cameras were placed facing bird feeders and three placed a minimum of 60 m away from the feeders. Species presence was recorded three days a week from 12:00 am Monday …
