Genetic Considerations For The Conservation Of The Red Junglefowl, Courtney Lee Mcpheron

University Honors Theses

The undomesticated wild populations of our domestic species deserve heightened consideration when it comes to their conservation. Not only do they carry significant socio-cultural and economic roles, but they offer an exceptionally unique case study for population genetics. The red junglefowl (Gallus gallus) of southern and south-eastern Asia is considered to be the living ancestor and progenitor of the domestic chicken. This literature review examines how published research has evaluated its genetic relationship with the chicken and implications for its conservation. A special emphasis is given to the threat of genetic introgression with domestic and feral chicken populations …

Use Of Highway Infrastructure By Bats: A Literature Review And Survey Of The Trans-Pecos Region Of Texas, Holly G. Wilson, Stirling J. Robertson, Richard D. Stevens

Western North American Naturalist

Bats are important components of nature and provide both monetary and nonmonetary benefits to mankind. While anthropogenic effects on wildlife and their habitats are typically viewed as negative, highway infrastructure might benefit numerous species of plants and animals, bats in particular. Cracks, crevices, and grooves within structures provide places for bats to roost. Here we review the literature on this topic as well as describe results of our own survey of bridges and culverts in the Trans-Pecos of Texas. We surveyed 204 bridges and 768 culverts between 2018 and 2019. We observed 7 species of bats using bridges or culverts …

Preliminary Evidence Of Anticoagulant Rodenticide Exposure In American Kestrels (Falco Sparverius) In The Western United States, Evan R. Buechley, Dave Oleyar, Jesse L. Watson, Jennifer Bridgeman, Steven Volker, David A. Goldade, Catherine E. Swift, Barnett A. Rattner

United States Geological Survey: Staff Publications

Although there is extensive evidence of declines in the American Kestrel (Falco sparverius) population across North America, the cause of such declines remains a mystery. One hypothesized driver of decline is anticoagulant rodenticide (AR) exposure, which could potentially cause mortality or reduced fitness. We investigated AR exposure in wild American Kestrels in Utah, USA. We collected and tested for AR residues in liver samples (n = 8) from kestrels opportunistically encountered dead and in blood samples (n = 71) from live wild kestrels, both nestlings and adults. We found high detection rates in both tissues. Adult …

First Report Of Regeneration In The Genus Mesobuthus (Scorpiones: Buthidae), Rıdvan Kurt, Ersen A. Yağmur, Gülhanım Çelik

Euscorpius

A new example of scorpion leg regeneration is reported in an adult male Mesobuthus mesopotamicus (Penther, 1912). A claw (pretarsus) was observed to regenerate at the distal end of the tibia of the left leg II. The regeneration case is described and illustrated.

Limits To Sentience, Donald M. Broom

Animal Sentience

There are many parallels between cellular function in animals and plants. Plants can have complex interactions with their environments. But they lack a central nervous system, which is a prerequisite for sentience (the capacity to feel). In my view the suggestion that plants are sentient is not only empirically incorrect but potentially harmful to the efforts to protect the welfare of sentient beings.

Equine Navicular Syndrome, Kylie Stephens, Karl Hoopes

All Current Publications

Equine navicular syndrome has a large effect on the horse industry by accounting for up to one third of all chronic forelimb lamenesses. While the exact cause and development of this disease is still widely controversial, there are noticeable and significant changes to the internal anatomy and structures that could contribute to the possible onset of lameness. Three main causes are proposed that could play a role in the progression of this syndrome: biomechanical forces, vascular alterations, and chronic inflammation. The clinical signs of navicular syndrome can range from short choppy strides to intermittent lameness, as well as gait changes …

Playful Mouth-To-Mouth Interactions Of Belugas (Delphinapterus Leucas) In Managed Care, Jackson R. Ham, Malin K. Lilley, Riley J. Winchenski, Jesus Miranda, Ángel G. Velarde Dediós, Katie Kolodziej, Sergio M. Pellis, Heather M. Manitzas Hill

All Faculty Scholarship (Archived)

Belugas (Delphinapterus leucas) engage in many forms of play (e.g., object, water, locomotor), but no play is quite as curious as the unusual form of cooperative social play involving mouth-to-mouth interactions. These playful interactions are characterized by two belugas approaching each other head-to-head and interlocking their jaws, clasping one another, as if they were shaking hands. Observed in belugas both in the wild and in managed care, it is seemingly an important type of social play that offers a unique way of socializing with conspecifics. To describe this unusual behavior, a group of belugas in managed care was …

Basic Fibroblast Growth Factor Induces Proliferation And Collagen Production By Fibroblasts Derived From The Bovine Corpus Luteum, Corrine F. Monaco, Michele R. Plewes, Emilia Przygrodzka, Jitu W. George, Fang Qiu, Peng Xiao, Jennifer R. Wood, Andrea S. Cupp, John S. Davis

Department of Animal Science: Faculty Publications

Cyclic regression of the ovarian corpus luteum, the endocrine gland responsible for progesterone production, involves rapid matrix remodeling. Despite fibroblasts in other systems being known for producing and maintaining extracellular matrix, little is known about fibroblasts in the functional or regressing corpus luteum. Vast transcriptomic changes occur in the regressing corpus luteum, among which are reduced levels of vascular endothelial growth factor A (VEGFA) and increased expression of fibroblast growth factor 2 (FGF2) after 4 and 12 h of induced regression, when progesterone is declining and the microvasculature is destabilizing. We hypothesized that FGF2 activates luteal …

Microbiological Safety And Quality Of Ceviche, Poke, And Sushi Dishes Sold At Retail Outlets In Orange County, Ca, Grace E. Marquis, Samantha M. Covaia, Amanda M. Tabb, Courtney J. Kitch, Rosalee S. Hellberg

Spatial And Temporal Activity Patterns Among Sympatric Tree-Roosting Bat Species In An Agriculturally Dominated Great Plains Landscape, Christopher Fill, Craig R. Allen, John F. Benson, Dirac Twidwell

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

In agroecosystems, bats can provide a critical ecosystem service by consuming night-flying insect pests. However, many bats also face intense population pressures from human landscape modification, global change and novel diseases. To better understand the behavioral activity of different bat species with respect to space, time, habitat, and other bat species in this environment, we investigated species correlations in space and time over row crop agricultural fields. We used acoustic grids to document spatial and temporal co-occurrence or avoidance between bats and recorded eight species across the 10 field sites we sampled. All species significantly overlapped in two-dimensional space and …

Papers in Herpetology

PLESTIODON EGREGIUS INSULARlS (Cedar Key Mole Skink). REPRODUCTION. Plestiodon egregius insularis is the largest of five described subspecies (Mount 1965. Bull. Florida St. Mus. BioI. Sci. 9:183-213) and is known from only nine small islands off the coast of Levy County, Florida, USA. The only documented clutch size for P. e. insularis contained five eggs (Mount 1963. Am. MidI. Nat. 70:356-385). For wild P. egregius, Mount (1963, op. cit.) reported 2-9 (mean = 4.8) eggs for 13 clutches, and Hamilton and Pollack (1958. Herpetologica 14:25-28) found two nests of P. e. similis in Georgia containing five eggs each. In captivity, …

An Exploration Of Palauan Fishing Methods And Fisheries: A Study For The Conservation Of Dugongs, Mia Glover

Electronic Theses and Dissertations

The dugong (Dugong dugon) is an important marine mammal in Palau. However, current population dynamics are not well understood. This study aimed to connect scientific data with local knowledge by examining the social implications of changing fishing methods and their impact on dugong population dynamics in the face of climate change and fisheries commercialization. Through interviews with local fishers, it was found that destructive fishing methods like trawling and long lining have led to habitat loss and degradation for dugongs. These tactics, driven by economic factors, have disrupted the delicate balance between human activities and the preservation of dugong habitats, …

Effects Of Mature Recombinant Gdf9 And Bmp15 On In-Vitro Maturation Of Bovine Oocytes And Subsequent Embryo Development And Effects Of Antioxidants On Blastocyst Re-Expansion Rates, Jamie Thompson

Master's Theses

In-vitro produced embryos (IVP) differ greatly from in-vivo derived embryos (IVD) in gene expression, metabolism, development, and cryotolerance which limit the widespread use of this technology. In-vitro maturation (IVM) is one of the most important components for successful in-vitro embryo development. Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) have been found to be essential during oocyte maturation and thus female fertility. These proteins are oocyte secreted factors (OSFs) and are produced with pro- and mature protein regions where the pro-regions are thought to aid in protein folding and dimerization where heterodimerization the two proteins has been …

However, only limited species coverage vaccines have been available for commercial turkey producers. This study aimed to assess the effect of an E. meleagrimitis vaccine candidate, with and without amprolium intervention, on performance and oocyst shedding. Additionally, the effect of vaccination, amprolium treatment, and E. meleagrimitis challenge on intestinal integrity and microbiome composition was evaluated.

Methods: Experimental groups included: (1) NC (non-vaccinated, non-challenged control); (2) PC (non-vaccinated, challenged control); (3) VX + Amprol (E. meleagrimitis candidate vaccine + amprolium); and …

Peripheral And Central Impact Of Methionine Source And Level On Growth Performance, Circulating Methionine Levels And Metabolism In Broiler Chickens, Craig W. Maynard, Elizabeth Gilbert, Frances Yan, Mark A. Cline, Sami Dridi

Poultry Science Faculty Publications and Presentations

The present study was designed to evaluate the effects of DL-methionine (DL-Met) 2-hydroxy-4-(methylthio) butanoic acid (HMTBa), or S-(5′-Adenosyl)-L-methionine chloride (SAM), using feeding trial and central administration, on live performance, plasma metabolites, and the expression of feeding-related hypothalamic neuropeptides in broilers raised to a market age (35 d). Final average body weight (BW) and feed conversion ratio (FCR) from the feeding trial exceeded the performance measurements published by the primary breeder. At d35, the MTBHa group had better BW and lower feed intake, which resulted in a better FCR than the DL-Met group at 87 TSAA to lysine. At the molecular …

Rethinking The Status And Temporal Occurrence Of The American Woodcock In Nebraska Because Of Its Unusual Life History, Joel G. Jorgensen, Stephen J. Brenner

Nebraska Bird Review

Historical distribution and range expansion -- We reviewed existing information to evaluate conclusions by previous authors (e.g., Sharpe et al. 2001, Silcock and Jorgensen 2023) that woodcock have expanded their range west since settlement of Nebraska by Euro-Americans. We also provide additional context about the species’ distribution over time using regional resources.

Temporal occurrence and abundance -- We used data from woodcock outfitted with satellite transmitters 2021-2022 and compared it with occurrence data from two sources, eBird (eBird.org 2023) from all years through 2022 and the SFRs in the Nebraska Bird Review 1994–2019. We chose not to use SFR data …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera

Dissertations, Theses, and Capstone Projects

Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Movement Patterns Of Two Bat Species Active During Winter In The Southeastern United States, Reilly T. Jackson, Emma V. Wilcox, Riley F. Bernard

Biological Sciences Faculty Publications and Presentations

During winter in the southeastern United States, cavernicolous bats, many species of which are susceptible to white-nose syndrome, periodically arouse from torpor and occasionally leave hibernacula. We investigated the winter movements and habitat use of two bat species persisting during the white-nose syndrome epizootic: the gray bat Myotis grisescens and the eastern small-footed bat Myotis leibii. We deployed very-high-frequency radio transmitters on individual bats captured outside hibernacula to investigate activity, which may include foraging, during winter. We tracked bats from release at the cave entrance until their transmitter signal was lost or they remained stationary for 15 min or …

Habitat Occupancy And Use For Bat Species Of Concern On The Buffalo National River, James W. Gore

Student Theses and Dissertations

Populations of several North American bat species have been in decline for several years. Much of this decline is attributed to white-nose syndrome (WNS). To better understand the effects of WNS by increasing our understanding of the bats’ foraging habits, I used bat calls collected by National Park Service personnel on the Buffalo National River, Arkansas, and estimated the bats’ foraging habitat occupancy and relative use. I determined that 1.) a false-positive occupancy model is valid for occupancy estimation when using multiple acoustic bat-id programs; 2.) as of 2016, the progression of WNS had yet to affect bat occupancy on …
