Westward Expansion Of The Evening Bat (Nycticeius Humeralis) Into Dawson And Lincoln Counties Of Central Nebraska, Jamila Bajelan, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Evening Bat (Nycticeius humeralis) is a small, migratory species of temperate woodlands in the eastern United States. Along its western distributional edge in the Great Plains, this species resides in wooded riverine corridors. In recent decades, the distribution of Evening Bats has expanded westward throughout the Great Plains. Herein, we report on two county records that further document the distributional expansion of Evening Bats into central Nebraska. In 2019 and 2022, Evening Bats were collected in Lincoln and Dawson counties, respectively, in woodlands adjacent to the Platte River. Increases in wooded habitats along prairie waterways likely has …

Urbanization Affects Web Abundance And Aggregation Of A Funnel‑Weaving Spider, Agelenopsis Pennsylvanica (Agelenidae), Brandi J. Pessman, Madison Hays, Earl Agpawa, Eileen Hebets

Eileen Hebets Publications

Animals distribute themselves within habitats based on a variety of environmental conditions, including those impacted by urbanization. Suspected global declines in urban arthropod biodiversity have required that we examine how urban conditions affect the distribution of this ecologically important group. Throughout North America, funnel-weaving spiders (Agelenidae) are prevalent across urban habitats and actively choose sites to build webs. We compared Agelenopsis pennsylvanica abundance and distribution between two distinct urban habitats: an urban center (university campus) and an urban forest (city park). These urban habitats differed significantly in features like plant diversity and proximity to roads and highways. We searched along …

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 …

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 …

I Ain't Afraid Of No Crab: Intertidal Gastropod Littorina Littorea Behavioral Response To Predation Risk By Carcinus Maenas, Isabelle Erin Smy

Honors College

Littorina littorea is an intertidal, invasive gastropod species common in the Gulf of Maine. In this paper, I studied the avoidance and risk-reducing behavioral responses of L. littorea to predation risk by invasive crustacean species Carcinus maenas. Avoidance and risk-reducing behavior in this study are defined by the tendency to move towards the edge and out of a simulated tide pool and the tendency to reduce feeding. The goal of this study was to determine whether the exposure to chemical cues of predators resulted in an increase in avoidance behavior, risk-reducing behavior, and a reduction in the time before the …

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 …

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 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 …

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 …

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 …

Data To Accompany "Plastic Heat-Avoidance Behavior In Response To Damage Of 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 …

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 …
