Does Bambi Need Privacy? The Impact Of Human Recreational Trail Traffic On Abundance And Daily Activity Of The White-Tailed Deer (Odocoileus Virginianus), Diana Alvarez
Journal of Interdisciplinary Undergraduate Research
Humans have a significant impact on wildlife populations. Although not as obvious, even non-consumptive recreational activities (i.e. hiking and mountain biking) can impact wildlife. Previous research has suggested that human traffic can impact the movement patterns of the white-tailed deer (Odocoileus virginianus). Specifically, as human traffic increases, deer sightings decrease. Also, due to their crepuscular nature, deer peak activity is at dawn and dusk, yet one study reported a decrease in deer sightings in the evening that seemed to correspond to a peak in human traffic. However, the cause-and-effect relationship between human traffic and deer daily movements has …
The First Troglobitic Scorpions From Hispaniola, Greater Antilles: Two New Species Of Cazierius Francke, 1978 (Scorpiones: Diplocentridae), Rolando Teruel, Solanlly Carrero Jiménez, Gabriel De Los Santos
The First Troglobitic Scorpions From Hispaniola, Greater Antilles: Two New Species Of Cazierius Francke, 1978 (Scorpiones: Diplocentridae), Rolando Teruel, Solanlly Carrero Jiménez, Gabriel De Los Santos
Euscorpius
Two new species of the Greater Antillean endemic scorpion genus Cazierius Francke, 1978, are herein described from the island of Hispaniola. They were found inside isolate limestone caves in the Dominican Republic and are fully troglomorphic, thus, apparently being strict troglobites that represent the first ever documented for this genus. The present additions raise the number of Hispaniolan species of both Cazierius and the family Diplocentridae Karsch, 1880, to five and ten, respectively.
Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Biology ETDs
Comparative phylogeography has historically been defined as the study of how genetic variation of co-distributed species has been shaped by biogeographical history. This is a mature field of study out of which several techniques have been developed directed at identifying the role ecology and geography in diversification patterns across time. I employ the tools developed in classical comparative phylogeography across multiple taxonomic scales and across regions that historically have been understudied. My first two chapters study the complex history of host-switching, codiversification, and reassortment of hantaviruses in their mammal hosts across North America. By taking a host-centric comparative phylogeographic approach …

Local And Systemic Cytokine, Chemokine, And Fgf Profile In Bacterial Chondronecrosis With Osteomyelitis (Bco)-Affected Broilers, Alison Ramser, Elizabeth Greene, Robert Wideman, Sami Dridi
Poultry Science Faculty Publications and Presentations
Complex disease states, like bacterial chondronecrosis with osteomyelitis (BCO), not only result in physiological symptoms, such as lameness, but also a complex systemic reaction involving immune and growth factor responses. For the modern broiler (meat-type) chickens, BCO is an animal welfare, production, and economic concern involving bacterial infection, inflammation, and bone attrition with a poorly defined etiology. It is, therefore, critical to define the key inflammatory and bone-related factors involved in BCO. In this study, the local bone and systemic blood profile of inflammatory modulators, cytokines, and chemokines was elucidated along with inflammasome and key FGF genes. BCO-affected bone showed …

The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel
The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel
Euscorpius
The Mexican scorpion Centruroides hoffmanni Armas, 1996 was described on the basis of a supposed adult female (actually a juvenile) from La Gloria, Arriaga Municipality, southwest of the Chiapas State. In its redescription, this species was also recorded from the southeastern of Oaxaca State. Nevertheless, in the recent revision of the “thorellii” species-group of the genus Centruroides Marx, 1890, a new species from Chiapas was misidentified as C. hoffmanni and, also, an erroneous new diagnosis was given for C. hoffmanni. In the present contribution, this new species is named Centruroides concordia sp. n., and the correct identity of C. …

24andmore: Using Genomics To Improve Walleye (Sander Vitreus) Stocking In Iowa, Rachel Mcdonnell
Three Minute Thesis (3MT®) at UNI
Walleye, Sander vitreus, is one of the top gamefish in Iowa. Due to poor natural reproduction in many Iowa waterbodies, populations are managed with stocking. There are two strains of walleye used to stock Iowa’s inland waters: a river strain derived from the Mississippi River near Genoa, WI and a lake strain derived from Spirit Lake, IA. Each strain may have unique characteristics relative to their environment that could affect the fitness and success of fish stocked. The goal of this study is to understand the genetic diversity within and between each strain to offer stocking guidance to the Iowa …
Genetic Effect Of Long-Term Angling Pressure On Bluegill Populations In Small Impoundments In Kansas, Morganne Borsh
Genetic Effect Of Long-Term Angling Pressure On Bluegill Populations In Small Impoundments In Kansas, Morganne Borsh
Three Minute Thesis (3MT®) at UNI
Bluegill (Lepomis macrochirus) is a versatile sport fish popularly fished across Kansas. Over the last decade, Bluegill catch rates have decreased, likely from high angler harvest rates of larger individuals. Large males that exhibit parental care have high growth rates and aggressively defend nests, making them vulnerable to angling. Males that display cuckoldry behavior reach maturity sooner, exhibit slower growth rates, and are generally smaller. The goal of this study is to determine if fisheries-induced evolution resulting from long-term harvest has led to a decline in the growth rate of Bluegill. A total of 100 individuals were sampled from ten …
Brood Abundance And Invertebrate Availability In Crop-Dominated Landscapes In The Prairie Pothole Region, Catrina V. Terry
Brood Abundance And Invertebrate Availability In Crop-Dominated Landscapes In The Prairie Pothole Region, Catrina V. Terry
LSU Master's Theses
The Prairie Pothole Region (PPR) is the most important region for ducks in North America, producing over half the ducks on the continent, and it is a priority landscape for wetland and grassland conservation. Agricultural expansion has changed the PPR, and the majority of grasslands and potholes have been converted into row-crops. The loss of nesting habitat has directly caused nest success to decline. Most of the remaining wetlands are surrounded by row-crops, and are considered lower quality because they receive runoff of sediment and chemicals, which may decrease primary forage for young ducklings as well as inhibit wetland vegetation. …
Protein Kinase A And 59 Amp-Activated Protein Kinase Signaling Pathways Exert Opposite Effects On Induction Of Autophagy In Luteal Cells, Emilia Przygrodzka, Corrine F. Monaco, Michele R. Plewes, Guojuan Li, Jennifer R. Wood, Andrea Cupp, John S. Davis
Protein Kinase A And 59 Amp-Activated Protein Kinase Signaling Pathways Exert Opposite Effects On Induction Of Autophagy In Luteal Cells, Emilia Przygrodzka, Corrine F. Monaco, Michele R. Plewes, Guojuan Li, Jennifer R. Wood, Andrea Cupp, John S. Davis
Department of Animal Science: Faculty Publications
In the absence of pregnancy the ovarian corpus luteum undergoes regression, a process characterized by decreased production of progesterone and structural luteolysis involving apoptosis. Autophagy has been observed in the corpus luteum during luteal regression. Autophagy is a self-degradative process important for balancing sources of cellular energy at critical times in development and in response to nutrient stress, but it can also lead to apoptosis. Mechanistic target of rapamycin (MTOR) and 5′ AMP-activated protein kinase (AMPK), key players in autophagy, are known to inhibit or activate autophagy, respectively. Here, we analyzed the signaling pathways regulating the initiation of autophagy in …

A population of cows with excess androstenedione (A4; High A4) in follicular fluid, with follicular arrest, granulosa cell dysfunction, and a 17% reduction in calving rate was previously identified. We hypothesized that excess A4 in the ovarian microenvironment caused the follicular arrest in High A4 cows and that vascular endothelial growth factor A would rescue the High A4 phenotype. In trial 1, prior to culture, High A4 ovarian cortex (n=9) had greater numbers of early stage follicles (primordial) and fewer later-stage follicles compared to controls (n=11). Culture for 7 days did not relieve this follicular arrest; …

Roman L. Hruska U.S. Meat Animal Research Center: Reports
River buffalo is an agriculturally important species with many traits, such as disease tolerance, which promote its use worldwide. Highly contiguous genome assemblies of the river buffalo, goat, pig, human and two cattle subspecies were aligned to study gene gains and losses and signs of positive selection. The gene families that have changed significantly in river buffalo since divergence from cattle play important roles in protein degradation, the olfactory receptor system, detoxification and the immune system. We used the branch site model in PAML to analyse single-copy orthologs to identify positively selected genes that may be involved in skin differentiation, …

Roman L. Hruska U.S. Meat Animal Research Center: Reports
Bovine viral diarrhea virus’s (BVDV) entry into bovine cells involves attachment of virions to cellular receptors, internalization, and pH-dependent fusion with endosomal membranes. The primary host receptor for BVDV is CD46; however, the complete set of host factors required for virus entry is unknown. The Madin-Darby bovine kidney (MDBK) cell line is susceptible to BVDV infection, while a derivative cell line (CRIB) is resistant at the level of virus entry. We performed complete genome sequencing of each to identify genomic variation underlying the resistant phenotype with the aim of identifying host factors essential for BVDV entry. Three large compound deletions …

Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck
Faculty Publications
Cetaceans are potentially at risk of poor welfare due to the animals’ natural reliance on sound and the persistent nature of anthropogenic noise, especially in the wild. Industrial, commercial, and recreational human activity has expanded across the seas, resulting in a propagation of sound with varying frequency characteristics. In many countries, current regulations are based on the potential to induce hearing loss; however, a more nuanced approach is needed when shaping regulations, due to other non-hearing loss effects including activation of the stress response, acoustic masking, frequency shifts, alterations in behavior, and decreased foraging. Cetaceans in managedcare settings share the …

Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular pastime in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler surveys and their importance to fisheries management at state scales, regional and national coordination among these activities is minimal, limiting data applicability for larger-scale management practices and research. Here, we introduce the U.S. Inland Creel and Angler Survey Catalog (CreelCat), a first-of-its-kind, publicly available national database of …
Moraxella Species Associated With Infectious Bovine Keratoconjunctivitis: Detection, Characterization, And Immunity, Matthew M. Hille
Moraxella Species Associated With Infectious Bovine Keratoconjunctivitis: Detection, Characterization, And Immunity, Matthew M. Hille
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Infectious bovine keratoconjunctivitis (IBK) represents the most common ocular disease of cattle. Moraxella bovis (M. bovis) is the only bacteria proven to cause IBK under experimental conditions. A closely related bacteria, Moraxella bovoculi (M. bovoculi) is cultured from IBK lesions more frequently than M. bovis, and is suspected to cause IBK, although a causal relationship between M. bovoculi and IBK has not been confirmed experimentally. Two distinct genotypes were recently characterized in M. bovoculi based on whole genome sequencing. Genotype 1 M. bovoculi appears to represent a potential pathogen …

The scale and drivers of marine biodiversity loss are being revealed by the International Union for Conservation of Nature (IUCN) Red List assessment process. We present the first global reassessment of 1,199 species in Class Chondrichthyes-sharks, rays, and chimeras. The first global assessment (in 2014) concluded that one-quarter (24%) of species were threatened. Now, 391 (32.6%) species are threatened with extinction. When this percentage of threat is applied to Data Deficient species, more than one-third (37.5%) of chondrichthyans are estimated to be threatened, with much of this change resulting from new information. Three species are Critically Endangered (Possibly Extinct), representing …

Environmental Studies Faculty Publications
Abundance estimates are essential for fisheries management, but estimating the abundance of open populations with low recapture rates has historically been unreliable. However, by using mark-recapture data modulated with survivability parameters obtained from analysis of acoustic telemetry data, more accurate abundance estimates can be made for species that exhibit these characteristics. One such species is the Atlantic sturgeon, for which abundance estimates were designated a research priority following precipitous population declines throughout the 20th century. We addressed this research need in the Saco River Estuary (SRE), a system where the Atlantic sturgeon has been extensively studied using mark-recapture and acoustic …

United States Department of Agriculture Wildlife Services: Staff Publications
Invasive wild pigs (Sus scrofa), also called feral swine or wild hogs, are recognized as among the most destructive invasive species in the world. Throughout the United States, invasive wild pigs have expanded rapidly over the past 40 years with populations now established in 38 states. Of the estimated 6.9 million wild pigs distributed throughout the United States, Texas supports approximately 40% of the population and similarly bears disproportionate ecological and economic costs. Genetic analyses are an effective tool for understanding invasion pathways and tracking dispersal of invasive species such as wild pigs and have been used recently …
Wildlife Responses To Livestock Guard Dogs And Domestic Sheep On Open Range, Daniel Kinka, Jeffrey T. Schultz, Julie K. Young
Wildlife Responses To Livestock Guard Dogs And Domestic Sheep On Open Range, Daniel Kinka, Jeffrey T. Schultz, Julie K. Young
United States Department of Agriculture Wildlife Services: Staff Publications
Domestic sheep (Ovis aries) are an attractant to carnivores; however, sheep are often accompanied by humans and livestock guardian dogs (LGDs; Canis familiaris), which defend sheep from depredation. Sheep also compete directly with wildlife for grazing resources. Although practiced for millennia in much of the world outside North America, the effect that transhumance has on wildlife is poorly understood. To test the effect of sheep bands (sheep, humans, and LGDs) on wildlife, we modeled the detection probability of wild mammals relative to the presence of sheep bands in the Northwestern United States. Sheep band presence was associated …

Faculty Research, Scholarly, and Creative Activity
Long-term environmental management to prevent waterfowl population declines is informed by ecology, movement behavior and habitat use patterns. Extrinsic factors, such as human-induced disturbance, can cause behavioral changes which may influence movement and resource needs, driving variation that affects management efficacy. To better understand the relationship between human-based disturbance and animal movement and habitat use, and their potential effects on management, we GPS tracked 15 dabbling ducks in California over ~4-weeks before, during and after the start of a recreational hunting season in October/November 2018. We recorded locations at 2-min intervals across three separate 24-h tracking phases: Phase 1) two …
