Effect Of Torpor On Host Transcriptomic Responses To A Fungal Pathogen In Hibernating Bats, Kenneth A. Field, Brent J. Sewall, Jenni M. Prokkola, Gregory G. Turner, Marianne Gagnon, Thomas M. Lilley, J Paul White, Joseph S. Johnson, Christopher L. Hauer, Deeann M. Reeder
Effect Of Torpor On Host Transcriptomic Responses To A Fungal Pathogen In Hibernating Bats, Kenneth A. Field, Brent J. Sewall, Jenni M. Prokkola, Gregory G. Turner, Marianne Gagnon, Thomas M. Lilley, J Paul White, Joseph S. Johnson, Christopher L. Hauer, Deeann M. Reeder
Faculty Journal Articles
Hibernation, the use of prolonged torpor to depress metabolism, is employed by mammals to conserve resources during extended periods of extreme temperatures and/or resource limitation. Mammalian hibernators arouse to euthermy periodically during torpor for reasons that are not well understood and these arousals may facilitate immune processes. To determine if arousals enable host responses to pathogens, we used dual RNA‐Seq and a paired sampling approach to examine gene expression in a hibernating bat, the little brown myotis (Myotis lucifugus). During torpor, transcript levels differed in only a few genes between uninfected wing tissue and adjacent tissue infected with …
Transcriptomics Of Learning, Pablo Iturralde
Transcriptomics Of Learning, Pablo Iturralde
Theses
Learning is a basic and important component of behavior yet we have very little empirical information about the interaction between mechanisms of learning and evolution. In our work, we are testing hypotheses about the neurogenetic mechanisms through which animal learning abilities evolve. We are able to test this directly by using experimentally evolved populations of flies, which differ in learning ability. These populations were previously evolved within the lab by creating worlds with different patterns of change following theoretically predicted effects on which enhanced learning will evolve. How has evolution acted to modulate genes and gene expression in the brain …
Species Distribution And Conservation Genetics Of The Upland And Midland Chorus Frogs (Pseudacris) In Kentucky, Tucker Cambridge
Species Distribution And Conservation Genetics Of The Upland And Midland Chorus Frogs (Pseudacris) In Kentucky, Tucker Cambridge
Masters Theses & Specialist Projects
The upland (Pseudacris feriarum) and midland (P. triseriata) chorus frogs are closely related cryptic species that are best distinguished genetically. The distribution of these species within the Commonwealth of Kentucky has previously been defined by only a handful of genetic samples, making delineation of range limits for each species difficult. Accurate understanding of species distributions, and the genetic structure within them, are vitally important for conservation management of amphibian species. In this study, I have collected genetic samples from across the putative ranges of P. triseriata and P. feriarum in Kentucky and used next-generation sequencing technology to generate more fine-scale …
Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King
Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King
Wildlife Damage Management Technical Series
Many wildlife management situations require the disposal of animal carcasses. These can include the lethal removal of wildlife to resolve damage or conflicts, as well as clean-up after mortalities caused by vehicle collisions, disease, oil spills (Figure 1) or other natural disasters. Carcasses must be disposed of properly to protect public sensitivities, the environment, and public health. Improper disposal of carcasses can result in public outrage, site contamination, injury to animals and people, and the attraction of other animals that may lead to wildlife damage issues. Concern over ground water contamination and disease transmission from improper carcass disposal has resulted …
Pollen Evidence Of Medicine From An Embalming Jar Associated With Vittoria Della Rovere, Florence, Italy, Karl Reinhard, Kelsey B. Lynch, Annie Larsen, Braymond Adams, Leon Higley, Marina Milanello Do Amaral, Julia Russ, Donatella Lippi, Johnica J. Morrow, Dario Piombino-Mascali
Pollen Evidence Of Medicine From An Embalming Jar Associated With Vittoria Della Rovere, Florence, Italy, Karl Reinhard, Kelsey B. Lynch, Annie Larsen, Braymond Adams, Leon Higley, Marina Milanello Do Amaral, Julia Russ, Donatella Lippi, Johnica J. Morrow, Dario Piombino-Mascali
Karl Reinhard Publications
Various samples of human viscera fragments, sponges, and cloth were collected from embalming jars belonging to members of the Medici family of Florence. One jar was labeled with the name Vittoria della Rovere, who died in March of 1694. This jar contained viscera fragments that were identified as a section of collapsed intestine. The intestine of the Vittoria della Rovere sample contained a large concentration of pollen belonging to the Myrtaceae family. The Myrtaceae pollen was sometimes observed in clusters during analysis, which is indicative of purposeful ingestion of flowers, buds, or a substance derived from floral structures. Thus, the …

Shifts In Assemblage Of Foraging Bats At Mammoth Cave National Park Following Arrival Of White-Nose Syndrome, Marissa M. Thalken, Michael J. Lacki, Joseph S. Johnson
Shifts In Assemblage Of Foraging Bats At Mammoth Cave National Park Following Arrival Of White-Nose Syndrome, Marissa M. Thalken, Michael J. Lacki, Joseph S. Johnson
Forestry and Natural Resources Faculty Publications
The arrival of white-nose syndrome (WNS) to North America in 2006, and the subsequent decline in populations of cave-hibernating bats have potential long-term implications for communities of forest-dwelling bats in affected regions. Severe declines in wintering populations of bats should lead to concomitant shifts in the composition and relative abundance of species during the staging, maternity, and swarming seasons in nearby forested habitats. We examined capture rates of bats collected in mist nets from 2009 to 2016 to evaluate summer patterns in abundance of species pre- and post-arrival of WNS to Mammoth Cave National Park, KY. The data demonstrated a …

Spatiotemporal Distribution Of Waterfowl Disease Outbreaks In Kansas, Usa, Thomas A. Becker, Adam A. Ahlers, Shane Hesting, David A. Haukos
The Prairie Naturalist
Causes and impacts of disease outbreaks in wild bird populations are rarely studied beyond documentation of large epizootic events. In Kansas, USA, a central disease surveillance and reporting protocol currently does not exist within the Kansas Department of Wildlife, Parks and Tourism, which has led to a lack of available knowledge of disease occurrences that could be used to predict and manage future outbreaks. We compiled historic records of documented waterbird disease outbreaks in Kansas from 1967–2014 and related the frequency of outbreaks with light geese (Ross’s goose [Anser rossii]; Snow goose [A. caerulescens]) populations from 1970–2014. We found 32 …

Population Structure, Demographic History, And Environmental Niche Of The Sand Fly Disease Vector Lutzomyia Shannoni (Dyar) (Diptera: Psychodidae) In The U.S., Mexico, And Colombia, Matthew E. Wolkoff
Population Structure, Demographic History, And Environmental Niche Of The Sand Fly Disease Vector Lutzomyia Shannoni (Dyar) (Diptera: Psychodidae) In The U.S., Mexico, And Colombia, Matthew E. Wolkoff
Biology Theses
Lutzomyia shannoni (Dyar, 1929) (Diptera: Psychodidae) is the only known sand fly vector of vesicular stomatitis virus, a putative leishmaniasis vector, and also boasts the widest distribution of any sand fly in the New World. Research on Lu. shannoni in Central and South America has revealed genetically divergent subpopulations; however, tentative analysis of Lu. shannoni in the U.S. has failed to detect any significant population structure, even between specimens collected from highly disparate localities.
The present study used four molecular markers to more closely investigate the population structure of Lu. shannoni in the U.S., and assess the species’ relationships with …
Distribution Patterns Of Gastrointestinal Parasites In Vervet Monkeys (Chlorocebus Pygerythrus) At Gombe National Park, Tanzania, Jared S. Bakuza
Distribution Patterns Of Gastrointestinal Parasites In Vervet Monkeys (Chlorocebus Pygerythrus) At Gombe National Park, Tanzania, Jared S. Bakuza
Tanzania Journal of Science
Vervet monkeys at Gombe National Park in western Tanzania constitute a key component of the park’s ecosystem through interactions with other animals and people in the area. However, the parasite fauna of these animals has not been investigated. Thus, 21 faecal samples obtained from the animals in September 2010 were examined for parasites using formol-ethyl technique. The parasites observed included Trichuris spp., Physaloptera spp., hookworms and unidentified nematodes. While egg counts for unidentified nematodes did not vary with vervet monkey communities (z = 0.759, p = 0.448), other parasites were significantly higher among vervets at north of the park near …
Defending Wild Dogs: Population Dynamics And Disease In Endangered African Wild Dogs, Elizabeth Claire Arredondo
Defending Wild Dogs: Population Dynamics And Disease In Endangered African Wild Dogs, Elizabeth Claire Arredondo
Graduate Theses and Dissertations
African wild dogs (Lycaon pictus) are endangered carnivores whose population is decreasing from habitat loss and fragmentation, interspecific competition, and disease. Survival rates are especially low in Kruger National Park (KNP), though it is unclear why. I estimated the abundance in KNP and survival rates over different time spans, six years and nine months, using public photographic survey data. In 2015, there were 298 (SE=12.1) individuals. Using a mark-recapture analysis in program R, I found that the survival rate between 2009-2015 was only 3.2%, and within the 9-month survey period (September 2014 – June 2015), monthly survival rates for the …

The Ecology And Feeding Behavior Of Mosquitoes In The Galapagos Islands, Samoa S. Asigau
The Ecology And Feeding Behavior Of Mosquitoes In The Galapagos Islands, Samoa S. Asigau
Dissertations
Mosquitoes remain important vectors in transmitting wildlife diseases. This dissertation aims to understand the role that mosquitoes play in transmitting wildlife diseases such as avian malaria, a protozoan parasite belonging to the genus Plasmodium. Using data from wild-caught mosquitoes captured in multiple years and across multiple islands on the Galapagos Archipelago, we describe distributional patterns of mosquitoes, their range limits and assess whether there exists a disease-free refuge as occurs in Hawaii. We show that altitudinal ranges for disease transmission of avian malaria may not be bounded by a stable disease-free refuge, since mosquitoes are found at all elevations, …

Recovering Parasites From Mummies And Coprolites: An Epidemiological Approach, Morgana Camacho, Adauto Araújo, Johnica J. Morrow, Jane E. Buikstra, Karl Reinhard
Karl Reinhard Publications
In the field of archaeological parasitology, researchers have long documented the distribution of parasites in archaeological time and space through the analysis of coprolites and human remains. This area of research defined the origin and migration of parasites through presence/absence studies. By the end of the 20th century, the field of pathoecology had emerged as researchers developed an interest in the ancient ecology of parasite transmission. Supporting studies were conducted to establish the relationships between parasites and humans, including cultural, subsistence, and ecological reconstructions. Parasite prevalence data were collected to infer the impact of parasitism on human health. In the …

Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, Jasmine Nicole Brown Baker
Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, Jasmine Nicole Brown Baker
LSU Doctoral Dissertations
Alu elements are approximately 300 base pair (bp) primate specific non- autonomous retrotransposons. Alu elements, a short interspersed element (SINE), account for high copy numbers in all primate genomes. Numerous Alu element subfamilies have undergone varying degrees of activity and amplification within primates. Identification of these subfamilies has proved to be very informative in elucidating phylogenies and as phylogenomic markers. Squirrel monkeys, genus Saimiri, are one of the most well-known neotropical primates and the second most commonly used laboratory monkey. Squirrel monkey species diverged approximately 1.5 million years ago and are native to South America. Despite being well-known, there …

Taxonomy is a scientific discipline that has provided the universal naming and classification system of biodiversity for centuries and continues effectively to accommodate new knowledge. A recent publication by Garnett and Christidis expressed concerns regarding the difficulty that taxonomic changes represent for conservation efforts and proposed the establishment of a system to govern taxonomic changes. Their proposal to “restrict the freedom of taxonomic action” through governing subcommittees that would “review taxonomic papers for compliance” and their assertion that “the scientific community's failure to govern taxonomy threatens the effectiveness of global efforts to halt biodiversity loss, damages the credibility of science, …
Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo
Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo
Dissertations
The large number of emergent infectious diseases witnessed in the past few decades has increased interest in the ecology and distribution of potentially threatening pathogens worldwide. Island species are often considered more vulnerable to parasites due to their impoverished parasite communities, long isolation from disease and low genetic diversity. Avian surveys done by our group on the Galapagos Islands have found various pathogens infecting their endemic avifauna, including haemosporidian parasites of the genera Plasmodium and Haemoproteus. My research seeks to understand the relationships between two haemosporidian parasites (blood parasites) and their multiple bird hosts in Galapagos and to explore …
Sequestered Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Provide Variable Protection From Microbial Pathogens, K. J. Hovey, E. M. Seiter, Erin E. Johnson, Ralph Saporito
Sequestered Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Provide Variable Protection From Microbial Pathogens, K. J. Hovey, E. M. Seiter, Erin E. Johnson, Ralph Saporito
2018 Faculty Bibliography
Most amphibians produce their own defensive chemicals; however, poison frogs sequester their alkaloid-based defenses from dietary arthropods. Alkaloids function as a defense against predators, and certain types appear to inhibit microbial growth. Alkaloid defenses vary considerably among populations of poison frogs, reflecting geographic differences in availability of dietary arthropods. Consequently, environmentally driven differences in frog defenses may have significant implications regarding their protection against pathogens. While natural alkaloid mixtures in dendrobatid poison frogs have recently been shown to inhibit growth of non-pathogenic microbes, no studies have examined the effectiveness of alkaloids against microbes that infect these frogs. Herein, we examined …

Can Nondolphins Commit Suicide?, David M. Peña-Guzmán
Animal Sentience
This Response addresses the scientific and philosophical criticisms of my 2017 target article “Can nonhuman animals commit suicide?” It defends my key claims and explores topics (such as animal judgment, animal theory of mind, and the evolution of suicide) that did not appear in the original article. It also points out areas in which further research is needed and concludes that we should be wary of accusations of “anthropomorphism” in debates about animal suicide.

Due to the worldwide decline of biodiversity, protected nature reserves are necessary for species facing extinction. Many frog species have been experiencing rapid population decline and extinction due to the threat of the fungus Batrachochytrium dendrobatidis (Bd), which inflicts the highly transmittable and deadly disease chytridiomycosis. Chytridiomycosis causes increased skin tissue growth which disrupts respiration and the maintenance of water balance, which can ultimately lead to death. Certain ecological and geographical characteristics have been studied in order to assess their influence on Bd’s prevalence. Specifically, it is hypothesized that high elevations, lotic habitats, and low species richness have a positive …

United States Department of Agriculture Wildlife Services: Staff Publications
Nutria, a semi-aquatic, South American rodent, was introduced to Maryland during the early 1940s. Originally brought to the area for fur farms, the market never established and animals were released or escaped. Nutria thrived, destroying coastal wetlands which resulted in negative environmental and economic impacts to the Chesapeake Bay region. To preserve and protect valuable wetland resources, the Chesapeake Bay Nutria Eradication Project (CBNEP) was established in 2002 through a partnership between the United States Fish and Wildlife Service, the United States Department of Agriculture’s Wildlife Services, Maryland Department of Natural Resources, and many state agencies and non-governmental organizations.

Modeling The Disappearance Of The Neanderthals Using Concepts Of Population Dynamics And Ecology, Michael F. Roberts, Stephen E. Bricher
Faculty Publications
Current hypotheses regarding the disappearance of Neanderthals (NEA) in Europe fall into two main categories: climate change, and competition. Here we review current research and existing mathematical models that deal with this question, and we propose an approach that incorporates and permits the investigation of the current hypotheses. We have developed a set of differential equations that model population dynamics of anatomically modern humans (AMH) and NEA, their ecological relations to prey species, and their mutual interactions. The model allows investigators to explore each of the two main categories or combinations of both, as well as various forms of competition …
Evaluating Bighorn Sheep Herd Response After Selective Removal Of Mycoplasma Ovipneumoniae Chronic Shedders, Tyler J. Garwood
Evaluating Bighorn Sheep Herd Response After Selective Removal Of Mycoplasma Ovipneumoniae Chronic Shedders, Tyler J. Garwood
Electronic Theses and Dissertations
Infected individuals vary in their contribution to disease persistence, and chronically infected individuals may sustain disease in a population. One disease that might persist in a population through chronically infected individuals is pneumonia in wild sheep. Mycoplasma ovipneumoniae (Mo), a pathogen of Caprinae commonly present in domestic sheep and goats, strongly correlates with pneumonia epizootics when it infects wild sheep populations. These epizootics can cause 40-100% herd mortality in an initial all-age dieoff, precipitate annual lamb mortality as high as 100% in following years, and sustain adult mortality long after initial all-age dieoffs. We conducted an experiment in the Black …
