Molecular Evidence Suggests Multiple Evolutionary Origins Of Sociality In The Polyphenic Spider Anelosimus Studiosus (Araneae: Theridiidae)., Nathaniel O. Weber
Molecular Evidence Suggests Multiple Evolutionary Origins Of Sociality In The Polyphenic Spider Anelosimus Studiosus (Araneae: Theridiidae)., Nathaniel O. Weber
Electronic Theses and Dissertations
Anelosimus studiosus exhibits two behavioral phenotypes: subsocial and social. This is the only documented spider inhabiting a temperate climate exhibiting social behavior. While the subsocial phenotype is most common throughout the range, the social behavior occurs in isolated pockets in northern latitudes. This study examines the origins of the social phenotype within a segment of the spider's range. Two hypotheses are tested: 1) pockets of social behavior represent a single origin or 2) pockets of social behavior represent local evolutions, thus leading to multiple origins of evolution. Microsatellite loci were used to determine genetic structure of the population and to …
Lack Of Rhythmicity In The Honey Bee Queen: An Investigation Of Temporal Behavioral Patterns In Apis Mellifera Ligustica., Jennifer N. Johnson
Lack Of Rhythmicity In The Honey Bee Queen: An Investigation Of Temporal Behavioral Patterns In Apis Mellifera Ligustica., Jennifer N. Johnson
Electronic Theses and Dissertations
Little is known about the behavioral patterns of honey bee queens. To determine if mated honey bee queens possess diel rhythmicity in behavior, we observed them in glass-sided observation hives using three types of observation regimes: focal studies consisting of 2-hour and 24-hour continuous observations as well as scan-sampling of multiple queens. All behaviors (active: walking, inspecting, egg-laying, begging for food, feeding, and grooming self; inactive: standing) occurred at all times of day and night, but no queen showed consistent diel rhythmicity in any of the individual behaviors. There were no consistent diel differences in active versus inactive behaviors or …

University Faculty and Staff Publications
Declines in shark populations have sparked researchers and fishery managers to investigate more prudent approaches to the conservation of these fish. As managers strive to improve data collection for stock assessment, fisheries-independent surveys have expanded to include data-deficient areas such as coastal regions. To that end, a catch series from a nearshore survey off Alabama was combined with data from a concurrent offshore survey with identical methodology to examine the depth use of sharks across the continental shelf (2–366 m). The combined data set contained 22 species of sharks collected from 1995 to 2008: 21 species in the offshore data …
Coaching Efficacy With Academic Leaders: A Phenomenological Investigation, Deanna Lee Vansickel-Peterson
Coaching Efficacy With Academic Leaders: A Phenomenological Investigation, Deanna Lee Vansickel-Peterson
College of Education and Human Sciences: Dissertations, Theses, and Student Research
The purpose of this psychological phenomenological research was to understand the efficacy of life coaching from the perspective of academic leaders. To date, not one investigation or attempt has been made towards the above stated purpose. This study includes a theoretical overview and a review of the coaching literature from Socrates (469-399 BC) to current day Humanistic theory presented in part by Roger (1902-1987). This process included data collection from five academic leaders who have been coached for at least two years. Levels of analysis of 365 statements, quote and/or comments produced finding of efficacy in life coaching with academic …
On The Evidence For Species Coexistence: A Critique Of The Coexistence Program, Adam M. Siepielski, Mark A. Mcpeek
On The Evidence For Species Coexistence: A Critique Of The Coexistence Program, Adam M. Siepielski, Mark A. Mcpeek
Dartmouth Scholarship
A major challenge in ecology is to understand how the millions of species on Earth are organized into biological communities. Mechanisms promoting coexistence are one such class of organizing processes, which allow multiple species to persist in the same trophic level of a given web of species interactions. If some mechanism promotes the coexistence of two or more species, each species must be able to increase when it is rare and the others are at their typical abundances; this invasibility criterion is fundamental evidence for species coexistence regardless of the mechanism. In an attempt to evaluate the level of empirical …
Ecological Effects Of Virus-Resistant Transgenic Squash, Holly R. Prendeville
Ecological Effects Of Virus-Resistant Transgenic Squash, Holly R. Prendeville
School of Biological Sciences: Dissertations, Theses, and Student Research
Two ecological risks associated with the use of transgenic crops include the effects of transgene products on non-target organisms and the effects of a transgene after it moves from crops into a wild plant population. In work presented here, we specifically investigate the ecological risks of virus-resistant transgenic squash. We observed pollinator behavior to determine if pollinators are affected by nontarget effects of the virus-resistant transgene. We found that pollinator behavior did differ between conventional and virus-resistant transgenic squash due to pleiotropic effects of the transgene. This difference in pollinator behavior can affect plant mating patterns, thereby affecting crop-wild hybridization …
Are Unfamiliar Neighbours Considered To Be Dear-Enemies?, Elodie Briefer, Fanny Rybak, Thierry Aubin
Are Unfamiliar Neighbours Considered To Be Dear-Enemies?, Elodie Briefer, Fanny Rybak, Thierry Aubin
Sentience Collection
Background: Discriminating threatening individuals from non-threatening ones allow territory owners to modulate their territorial responses according to the threat posed by each intruder. This ability reduces costs associated with territorial defence. Reduced aggression towards familiar adjacent neighbours, termed the dear-enemy effect, has been shown in numerous species. An important question that has never been investigated is whether territory owners perceive distant neighbours established in the same group as strangers because of their unfamiliarity, or as dear-enemies because of their group membership.
Methodology/Principal Findings: To investigate this question, we played back to male skylarks (Alauda arvensis) songs of adjacent neighbours, distant …
Scraping Behavior In Male White-Tailed Deer As A Potential Means Of Transmitting Chronic Wasting Disease, Travis C. Kinsell
Scraping Behavior In Male White-Tailed Deer As A Potential Means Of Transmitting Chronic Wasting Disease, Travis C. Kinsell
School of Natural Resources: Dissertations, Theses, and Student Research
Chronic wasting disease (CWD) has become a concern for wildlife managers and hunters across the United States. High prevalence of chronic wasting disease (CWD) in older male white-tailed deer (Odocoileus virginianus) suggests that sex-specific social behavior may contribute to the spread of the disease among males. Scraping is a marking behavior performed by male white-tailed deer during the rut in which a pawed depression and associated over-hanging branch are marked with saliva, glandular secretions, urine, and feces. We placed 71 and 35 motion-activated cameras on scrapes in DeSoto National Wildlife Refuge in western Nebraska and eastern Iowa from …
The Mosquito (Diptera: Culicidae) Fauna Of The Blackwater Ecological Preserve: Effects Of Prescribed Burns And Habitat Type On Mosquito Abundance And Distribution, Norman A. Grefe Lll
The Mosquito (Diptera: Culicidae) Fauna Of The Blackwater Ecological Preserve: Effects Of Prescribed Burns And Habitat Type On Mosquito Abundance And Distribution, Norman A. Grefe Lll
Biological Sciences Theses & Dissertations
While mosquitoes (Diptera: Culicidae) are among the most studied of insect groups, much remains unknown about their distribution and response to environmental impacts such as prescribed burns. Blackwater Ecological Preserve, located near Zuni, Virginia, is a relict long leaf pine barren, parts of which undergo periodic prescribed burns to maintain and restore this fire-dependent ecosystem. To assess the impact of prescribed burns on mosquito activity and to determine associations between seasonal patterns of adult mosquito activity and habitat type, CDC light traps baited with dry ice were set (rom late April through October at Blackwater Ecological Preserve during the 2005 …
Carrion Beetles Of The Blackwater Ecologic Preserve: Community Structure Seasonal Patterns And Habitat Use, Amy L. Simons
Carrion Beetles Of The Blackwater Ecologic Preserve: Community Structure Seasonal Patterns And Habitat Use, Amy L. Simons
Biological Sciences Theses & Dissertations
Carrion beetles (Silphidae) are important in the decomposition of carcasses in ecosystems. Two subfamilies, Nicrophorinae and Silphinae, differ in reproductive behaviors. The Nicrophinae, burying beetles, bury small carcasses to serve as food for the adults and their offspring. The Silphinae oviposit near larger carcasses. There is intense competition among all carrion beetles and other carrion feeders for carcasses, and beetle species have evolved seasonal activity patterns that minimize competition, such as when they are active and when they reproduce. Northern Silphidae communities are more diverse than southern communities, probably due to increased competition for carrion in the south.

The Significance Of The Male Display During Male-Male Interactions In Guppies (Poecilia Reticulata), Rebecca Nuffer, Samantha M. Alburn
The Significance Of The Male Display During Male-Male Interactions In Guppies (Poecilia Reticulata), Rebecca Nuffer, Samantha M. Alburn
Biological Sciences
Guppies, Poecilia reticulata, are a model species for studies of female preference based on male courtship displays; however, males also display to each other in an aggressive context, and little attention has been paid to the role of male-male displays. The display involves a male positioning his body in front or to the side of another male, arching his body, and quivering with his dorsal fin splayed. To understand what behaviors elicit a male display, we assigned individual males a dominance status. We then examined the relationship between dominance status and the number of displays delivered and received. By …
A Comparison Of The Singing Activity Of Carolina Wrens (Thryothorus Ludovicianus)) In Urban And Rural Settings, Shannon R. Trimboli
A Comparison Of The Singing Activity Of Carolina Wrens (Thryothorus Ludovicianus)) In Urban And Rural Settings, Shannon R. Trimboli
Masters Theses & Specialist Projects
As the earth’s landscape becomes increasingly urbanized, local wildlife must adapt to urban conditions or migrate to areas that are more rural. Urban wildlife face challenges such as direct loss of habitat, competition with non-native species, disturbance due to anthropogenic noise, and micro-climatic changes. Factors such as temperature, relative humidity, and noise affect the acoustical environment and may affect the ability of many animals, including birds, to communicate.
Understanding how urbanization affects birds’ singing behavior is critical because singing often plays a vital role in attracting mates and defending territories. In addition, as global climate change occurs it will become …
Maternal Effects In Transmission Of Self-Medicative Behavior From Mother To Offspring In Sheep, Udita Sanga
Maternal Effects In Transmission Of Self-Medicative Behavior From Mother To Offspring In Sheep, Udita Sanga
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Mammals begin learning food preferences in utero and maternally mediated influences early in life help offspring develop their feeding habits. Mammals also learn by individual experience to ingest medicinal compounds such as polyethylene glycol (PEG), which attenuates the negative post-ingestive effects of tannins, a group of potentially toxic plant secondary compounds. The objective of this study was to investigate the transmission of acquired self-medicative behavior from mother to offspring using polyethylene glycol (PEG) as a medicine to relieve malaise caused by tannins. I hypothesized that: 1) mothers trained to associate the beneficial effects of PEG while consuming tannins will pass …
Habitat Preference Of Nitrophila Species, Kari Hugie
Habitat Preference Of Nitrophila Species, Kari Hugie
Undergraduate Research Conference
Nitrophila occidentalis and Nirophlia mohavensis are both members of the same Family and Genus, and they both are found in the Great Basin region. They are the only members of the Genus Nitrophila native to the United States. Nitrophila occidentalisflourishes in the Great Basin, but Nitrophila mohavensis is endangered and limited to a few populations. Habitat analysis was done to the two species using GIS (Geographical Information Systems) to gain some new insight on how to preserve this endangered species. A discrete difference in soil alkalinity preference was found, which may help in saving N. mohavensis.
The Effects Of Food Quality On Preference And Incurred Risk In White-Tailed Deer (Odocoileus Virginianus), Travis Perlman, Jacob Stanton
The Effects Of Food Quality On Preference And Incurred Risk In White-Tailed Deer (Odocoileus Virginianus), Travis Perlman, Jacob Stanton
Undergraduate Research Conference
An observational study was concluded in Nacogdoches County, Texas, to determine if free-range white-tailed deer (Odocoileus virginianus) could assess forage value. Multiple parameters were recorded to determine if individuals were willing to incur hight levels of risk as they sought to maximize their fitness, through dietary selection. Our results indicated that individuals were willing to incur higher levels of risk, in order to attain higher quality food items.
Female Mate Choice Based Upon Male Motor Performance, John Byers, Eileen Hebets, Jeffrey Podos
Female Mate Choice Based Upon Male Motor Performance, John Byers, Eileen Hebets, Jeffrey Podos
Eileen Hebets Publications
Our goal in this essay is to review the hypothesis that females choose mates by the evaluation of male motor performance. We define motor performance as vigor, the ability to perform energetically expensive acts repeatedly, or as skill, the ability to perform difficult motor tasks well. Motor performance reflects most aspects of whole-organism performance that relate to survival, and thus should indicate, more reliably than ornaments do, individual male genetic quality and/or developmental history. Male sexual displays in many animal taxa contain elements of vigor and/or skill, and accumulating evidence suggests that females choose mates in nature based upon their …
Space Use And Mating Activities In The Speckled Rattlesnake, Xavier Glaudas
Space Use And Mating Activities In The Speckled Rattlesnake, Xavier Glaudas
UNLV Theses, Dissertations, Professional Papers, and Capstones
Our understanding of space use variation in response to the temporally varying importance of specific resources is poorly understood in reptiles, because spatial studies are rarely placed into an explicit ecological and behavioral context. I examined how space use differed between the mating and post-mating seasons, and how this variation related to three important resources, mating partners, food, and refuge, in an adult population of the speckled rattlesnake Crotalus mitchellii in the Mojave Desert of southwestern North America. During the mating season (late April to early June), Crotalus mitchellii increased distance traveled per unit time, because wide-ranging behavior likely enhances …
Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy
Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy
Biological Sciences
Emerita analoga, Pacific coast sand crabs, are an important biological component of the swash zone ecosystem. They have evolved the ability to burrow into sand, and burrowing speed is commonly used as an indicator of performance relevant for fitness in this species. Sand grain size varies among beaches, and crabs may be better adapted to to burrow in some sand types. We performed a completely crossed 3-factor experiment to determine how the sand grain size associated with beach-of-origin and rearing conditions influence burrowing in coarse and fine sand. Crabs from a fine sand beach and a coarse sand beach were …
A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur
A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur
Scholarship and Professional Work - LAS
We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …
What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech
What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The taxonomic identity of the historical and current wolf (Canis lupus L., 1758 or Canis lycaon Schreber, 1775 or their hybrids) population in Minnesota (MN) and the Great Lakes region has been, and continues to be, controversial. So too does its legal status under the U.S. Endangered Species Act. This review summarizes the morphological and genetic information about that population and concludes that historically the MN population consisted of a gray wolf (C. lupus) in the west and an eastern type (Canis lupus lycaon or C. lycaon) in the east with intergrades or hybrids between …
Physiological Status Of Male And Female Popillia Japonica (Coleoptera: Scarabaeidae) Affects Mating And Grouping Behavior, Natasha Tigreros, Rashmi Jadhav, Katelyn A. Kowles, Britto P. Nathan, Paul Switzer
Physiological Status Of Male And Female Popillia Japonica (Coleoptera: Scarabaeidae) Affects Mating And Grouping Behavior, Natasha Tigreros, Rashmi Jadhav, Katelyn A. Kowles, Britto P. Nathan, Paul Switzer
Faculty Research & Creative Activity
Because mating may be costly, sexually active males or females are predicted to be in relatively good physiological condition and may preferentially direct their mating behavior toward relatively high-quality mates. We tested this hypothesis in Japanese beetles (Popillia japonica Newman), a pest species in which males and females may be either isolated or in aggregations while feeding on host plants. We examined male size and lipid content and female size and egg load with respect to both their pairing status and whether they were isolated or in aggregations. Males that were paired had the highest lipid levels, and single, isolated …

Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather
Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather
Sentience Collection
Antipredator responses, especially those of open-ocean squid, have been seldom studied in the natural environment. Sepioteuthis sepioidea, observed by snorkellers near the shore in early morning/late afternoon, produced an average of eight moves of over 1m per hour, apparently mostly antipredator behaviours. Close approaches by herbivorous parrotfish elicited no response in 74% of encounters; otherwise, squid produced agonistic zebra stripes or startle-mantle-dots skin patterns. Predatory bar jack fish caused flight but not zebra displays, and squid usually paled and fled quickly (66%) from snapper. The speed of approach was the best predictor for flight and display responses to snapper, …
Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff
Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff
Veterinary Science and Medicine Collection
In many social sciurids, male territoriality confers significant mating advantages. We evaluated resident male paternity in Gunnison’s prairie dogs (Cynomys gunnisoni), a colonial ground-dwelling sciurid, where males and females cooperatively defend territories. Contrary to findings reported for other social sciurids, our results show that territorial resident males do not gain significant reproductive advantages. Resident males sired the majority of offspring from their respective territories only 10.5% of the time. A single non-resident male sired equal or greater number of offspring than any single resident male 71.2% of the time. While adult males were more likely to sire a greater number …

Ethology Collection
This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited behavior …

The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek
The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek
Proceedings of the North American Crane Workshop
Beginning in 2001, a reintroduction project was initiated using captive-reared whooping cranes (Grus americana) to establish a migratory flock in eastern North America. From May 2003 to August 2008, 23 of these birds were retrieved and translocated in 15 separate events. These individuals consisted of 14 cranes that had been led to Florida by ultralight aircraft on their first autumn migration (UL) and 9 cranes that had been directly released in autumn in Wisconsin (DAR). Of 104 (86 UL and 18 DAR) reintroduced individuals that eventually departed from their release location, 22% were later retrieved 1-3 times. Lake …

Home Range Size And Habitat Use Of Mississippi Sandhill Crane Colts, Scott G. Hereford, Tracy E. Grazia, Jereme N. Phillips, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Recruitment in the endangered Mississippi sandhill crane (Grus canadensis pulla) is minimal, with the population of 110 sustained by an annual augmentation of captive-reared juveniles. Suitability of available habitat quality is likely involved in nesting success. Thousands of hectares of pine savanna were restored for crane use, but it is not clear how much was being used by crane families. We used 3-g subcutaneous transmitters to radio-tag 27 colts over 6 years from 1998 to 2002 and 2004 to determine home range and habitat use. Using a hand-held receiver, H-antenna and standard triangulation, location data were collected twice …
