Energy-Saving Hypothermia Reduces Flight Ability In Mourning Doves, Jennie M. Carr, Steven L. Lima May 2012

Energy-Saving Hypothermia Reduces Flight Ability In Mourning Doves, Jennie M. Carr, Steven L. Lima

Symposium 2012

Overwintering birds are frequently exposed to thermal challenges that can quickly decrease energy reserves, thus leading to an increase in the risk of starvation. During these periods of energetic hardship, many avian species use nocturnal hypothermia to conserve energy that would otherwise be lost remaining warm throughout the night (McKechnie & Lovegrove 2002). However, a cool body temperature (Tb) may limit a bird’s ability to monitor the environment and may slow their response to a potential threat. Thus, birds likely trade-off between the benefits of energy-saving hypothermia and the potential costs of reduced behavioral responsiveness to predators (Welton et al. …


Endurance And Exercise Physiology In Urosaurus Ornatus: Sex And Morph Differences?, Elizabeth Christine Foulkes May 2009

Endurance And Exercise Physiology In Urosaurus Ornatus: Sex And Morph Differences?, Elizabeth Christine Foulkes

All-Inclusive List of Electronic Theses and Dissertations

Locomotory performance has been the focus of many ecological and evolutionary studies, and lizards have been a model system. While several studies have demonstrated interspecific differences in performance, few have examined intraspeciflc variation in performance and the suites of underlying physiological traits in tree lizards ( Uro.,·aurns ornatus) a species with alternative reproductive tactics that show variation in spatial use patterns. To assess the functional ecology of movement behaviors of male morphs and or females, I examined variation in exertion, plasma metabolites, plasma steroid hormones, and muscle fiber types in ornate tree lizards ( Urosaurus ornalus). In my study population, …


Influential Parasites: Importance Of Haemosporidian Parasite Infection In The White-Throated Sparrow, Amanda P. Jamison May 2008

Influential Parasites: Importance Of Haemosporidian Parasite Infection In The White-Throated Sparrow, Amanda P. Jamison

All-Inclusive List of Electronic Theses and Dissertations

The study of parasite-mediated selection, as originally postulated by Hamilton and Zuk ( 1982) in birds is an area of intense study as it allows us to test the significance of the relationship between host and parasite. Recent developments of resistance to treatments in humans for parasite induced disease, creates a place for this important research and emphasizes the need to find the connections and interactions in this relationship between ecology and infectious disease. The development of new molecular techniques has made the study of parasitism in birds and mammals easier and provides an efficient sensitive . methodology to detect …


Prey Naiveté: Evolutionary And Ecological Implications, Jonathan G. Cox Dec 2007

Prey Naiveté: Evolutionary And Ecological Implications, Jonathan G. Cox

All-Inclusive List of Electronic Theses and Dissertations

Despite its ecological importance, the concept of prey naivete has become a biological truism that receives little study. I explored the evolution of naivete and its likely influence on two major ecological patterns: a) the historically greater destructiveness of freshwater predator introductions, and b) the greater strength of aquatic trophic cascades. In a review of the ecological literature, I demonstrate that the conditions for the evolution of naivete (isolation) exist in freshwater habitats at multiple spatial scales. In addition, I show that freshwater prey exhibit naivete which could be responsible for the high impacts of freshwater predator introductions. I then …

Seasonal Changes In Thermal Conductance Of Bat Pelage: A Comparison Of The Eastern Red Bat (Lasiurus Borealis) And Big Brown Bat (Eptesicus Fuscus), Daniel Justin Judy

All-Inclusive List of Electronic Theses and Dissertations

Two species with different ecologies and natural histories use different morphological characteristics and thermoregulatory strategies to survive seasonal environmental changes. The purpose of this project was to investigate two such species, the eastern red bat (Lasiurus borealis) and big brown bat (Eptesicus fuscus). Red bats roost in the foliage of trees and occasionally leaf litter and have dense fur, as well as a furred interfemoral membrane. These two species differ in their morphology and roosting ecology in that big brown bats are generally larger with less dense fur, no fur on the interfemoral membrane, and are less exposed to environmental …

Effects Of Calcium Availability On The Reproductive Output Of Insectivorous Bats, Christina M. Booher Aug 2007

Effects Of Calcium Availability On The Reproductive Output Of Insectivorous Bats, Christina M. Booher

All-Inclusive List of Electronic Theses and Dissertations

Reproduction is a period of high calcium demand in vertebrates, and calcium deficiency can limit reproductive output in mammals. Insects are a poor calcium source, suggesting that insectivorous species are more likely to be calcium deficient. Pregnant big brown bats (Eptesicus fuscus) consume 10 times less calcium than they are estimated to require. To accommodate calcium demand during pregnancy, many mammals mobilize more calcium from the skeleton, and extensive bone loss has been observed in some bats during pregnancy. A conflict may arise between the female and developing embryo over allocation of limited calcium supplies, which could limit reproductive output …

All-Inclusive List of Electronic Theses and Dissertations

I investigated the use of torpor and arousals during winter of 2005 - 2006 by freeliving big brown bats (Eptesicus fuscus) by measuring skin temperature (remotely using data loggers) and used those measurements to estimate winter energy expenditure. Torpor bouts lasted for a mean of 3 .3 days ( d) with a mean of 3 .6 d and 2.2 d for males and females, respectively. There was no correlation between ambient temperature (Ta) during torpor and torpor bout length, but there was a significant correlation between Ta and length of the active period. Arousals lasted on average 5.0 hours (h). …


Rapid Assimilation Of Yolk Enhances Growth And Development Of Lizard Embryos From A Cold Environment, Melissa Ann Blake May 2006

Rapid Assimilation Of Yolk Enhances Growth And Development Of Lizard Embryos From A Cold Environment, Melissa Ann Blake

All-Inclusive List of Electronic Theses and Dissertations

Selection for rapid growth in cold environments results in a geographic pattern known as countergradient variation. The eastern fence lizard, Sceloporus undulatus, exhibits countergradient variation in growth rate across latitudinal clines. In a common-garden experiment, S. undulatus embryos from cold environments grew more efficiently than embryos warm environments, even when the energetic contents of eggs were equalized. To examine the physiological mechanisms of higher growth efficiency, I measured the energetics of embryos during the first 49 days of incubation. Specifically, I recorded body mass, residual yolk, total respiration, and developmental stage for embyos from two populations (Virginia and South Carolina). …


Comparing Immune Responses Of Juvenile And Adult Northern Fence Lizards, Sceloporus Undulatus, Zaïna Sandrine Kabange Dec 2005

Comparing Immune Responses Of Juvenile And Adult Northern Fence Lizards, Sceloporus Undulatus, Zaïna Sandrine Kabange

All-Inclusive List of Electronic Theses and Dissertations

Sex steroid hormones affect behavior and morphological traits important in sexual selection. Steroid hormones also play a role in the development and functioning of immune system components. The immunocompetence handicap hypothesis (Folstad and Karter, 1992) proposes that tradeoffs, mediated by plasma levels of testosterone, exist between the immune system and elaboration of secondary sexual traits. Endocrine-immune interactions are well documented in birds and mammals, and steroid hormones can be immunoenhancing or immunosuppressive. Relatively little work has examined the ontogeny of immune function, and the interactions between steroid hormones and the immune system in reptiles. The first experiment addressed the question …

Immune-Endocrine Interactions In The Lizard Sceloporus Undulatus Hyacinthinus: Testing An Assumption Of The Immunocompetence Handicap Hypothesis, Mukta Chakraborty

All-Inclusive List of Electronic Theses and Dissertations

The immunocompetence handicap hypothesis (IHH) was proposed by Folstad and Karter ( 1992) to describe the role of the endocrine system in ensuring honesty of sexual signaling. Numerous studies have investigated the assumptions of the IHH, but currently there is mixed evidential support in favor of the IHH. The first chapter of this thesis is a review examinining these studies, their limitations, and proposed alternative models and future directions. The second chapter of this thesis presents a study in which we experimentally assesss the testosterone immunosuppression assumption in adult male Sceloporus undulatus lizards. We manipulated circulating androgen levels (Day 0) …

The Ecology And Relationships Of Chiropteran Ectoparasitic Communities Of Indiana, Christopher Michael Ritzi

All-Inclusive List of Electronic Theses and Dissertations

The ectoparasites of bats are an important and largely unstudied area of mammalian ecology. The structure of ectoparasitic communities on bats, and their interactions with their hosts, may help in the understanding of roosting ecology, pa1iurition, and other aspects of host natural history. In this study, a vigorous survey of the ectoparasitic fauna of the bats ofindiana was undertaken, to determine if changes in species composition has occurred over the past 30 years. This survey resulted in the recovery of 51,980 parasites of 13 families from 2,816 host individuals of l O species, documenting 16 new host records and 14 …


Use Of Cre Recombinase And Sb Transposase To Engineer Transgenic Zebrafish, Jie Dong Dec 2004

Use Of Cre Recombinase And Sb Transposase To Engineer Transgenic Zebrafish, Jie Dong

All-Inclusive List of Electronic Theses and Dissertations

Current transgenesis has become easier for certain species due to the recent development of exogenous non site-specific recombination systems such as Sleeping Beauty (SB) transposon, and site-specific recombination systems such as Cre-loxP. Such recombination systems overcame two major problems caused by conventional transgenesis, position effect and copy number effect. SB is a reconstructed fish transposon that has shown to efficiently insert transgenes into heterologous mammalian chromosomes. The Cre-loxP system is frequently used to delete a given sequence from the genome or to target the integration of foreign DNA. The use of both systems in combination, however, has not yet been …


Thermal Adaptation Of Maternal And Embryonic Phenotypes In A Wide Spread Lizard (Sceloporus Undulatus), Christopher E. Oufiero Aug 2004

Thermal Adaptation Of Maternal And Embryonic Phenotypes In A Wide Spread Lizard (Sceloporus Undulatus), Christopher E. Oufiero

All-Inclusive List of Electronic Theses and Dissertations

Geographically widespread ectotherms encounter thermal gradients that generate variation in behavior, physiology and life-history. Because rates of physiological processes are very sensitive to temperature, cold environments are thought to favor genotypes that have relatively high capacities for growth despite environmental constraints. Two different adaptive responses can occur: (1) mothers in colder environments can allocate more energy to each offspring, or (2) offspring in colder environments make more efficient use of available resources. In this study, I examined both maternal adaptations and embryonic adaptations to environmental temperature. Evidence of maternal adaptations was assessed by examining the relationship between egg size and …


The Role Of Facial Pits In The Thermoregulatory Behavior Of Pitvipers (Viperidae: Crotalinae) Behavioral, Ecological And Phylogenetic Perspectives, Aaron R. Krochmal Dec 2003

The Role Of Facial Pits In The Thermoregulatory Behavior Of Pitvipers (Viperidae: Crotalinae) Behavioral, Ecological And Phylogenetic Perspectives, Aaron R. Krochmal

All-Inclusive List of Electronic Theses and Dissertations

Pitvipers (Viperidae: Crotalinae) possess unique sensory organs, the facial pits, capable of sensing subtle fluctuations in thermal radiation. Prey acquisition has long been regarded as the sole function of the facial pits. However, the ability to sense thermal radiation could also direct thermoregulatory behavior by remotely sensing nearby surface temperatures. Using a series ofbehavioral arenas of varying spatial complexity and ecological relevance, I surveyed the ability of western diamondback rattlesnakes (Crotalus atrox) to direct successful thermoregulatory movements with either functional or disabled facial pits. I found that western diamondback rattlesnakes could base thermoregulatory decisions on thermal radiation cues when their …

Movement Patterns In The Big Brown Bat (Eptesicus Fuscus), W. Adam Phelps

All-Inclusive List of Electronic Theses and Dissertations

Temperate insectivorous bats have historically used such structures as hollow trees, slabs of loose bark, foliage, and caves as roosts. With the advent of modern man in North America, human-built structures have become available to bats. Eptesicus fuscus is one of only two species of bats in the eastern United States that regularly utilize human structures as roosts, and the only one that regularly hibernates there. Individual ~- fuscus utilizing the attic of a church on the campus of St. Mary-of-the-Woods College (SMWC) were implanted with passive integrated transponder (PIT) tags. The electronic tag reader was placed near the only …


Thermoregulation In Swimming Mallard Ducklings (Anas Platyrhynchos), Aaron James Lynott May 2003

Thermoregulation In Swimming Mallard Ducklings (Anas Platyrhynchos), Aaron James Lynott

All-Inclusive List of Electronic Theses and Dissertations

Temperature regulation in birds has been studied for several decades. However, most studies have been limited to the thermal effects of air. This is surprising considering the abundance of waterfowl and the significant amount of time that many birds spend immersed in water. While we do know that water has a thermal conductivity that is 23 times that of air, the effect of water temperature on temperature regulation remains unknown. Though the thermal effect of water seemingly has a strong influence on the thermoregulation of birds, neonatal aquatic birds seem particularly susceptible. Many aquatic neonates, such as mallard ducklings, enter …
