Characterization Of The Vasotocin Receptor Subtype 4 (Vt4r) In The Brain And Pituitary Gland Of The Chicken, Gallus Gallus, Rajamani Selvam

Graduate Theses and Dissertations

The present study investigated the distribution of the vasotocin subtype four receptor (VT4R) in brain and pituitary gland of the chicken, Gallus gallus. The anterior pituitary cell types associated with the VT4R were also determined. Two polyclonal antibodies were raised in rabbit against a cocktail of peptides, 15 amino acids from the amino terminal region and 17 amino acids from the carboxy terminal region of VT4R receptor. The antibody was validated utilizing the Western blot and immunocytochemistry. A single band at 47KDa utilizing membrane protein extracts of chicken brain and pituitary tissues was shown for the VT4R antibody. A peptide …

Out With The Old And In With The New: A Comparison Between Molecular And Traditional Techniques To Identify Parasitized Birds, Christian Guerrero

College of Arts and Sciences Poster Presentations

Traditionally, the identification of blood parasites has been based on visual examination of blood smears. This approach depends on individual expertise in making blood smears and identifying parasites, which can vary widely from person to person. Recent work has shown that reading blood smears is significantly less sensitive than using molecular studies in identification. Thus, the accuracy of the data can fluctuate greatly. This project compares the ability of investigators to identify infected birds using microscopes and blood smears with their ability to identify infected birds through molecular analysis of blood from the same sample.

2011–2012 Christmas Bird Counts

Nebraska Bird Review

Fifteen counts, one more than last year, were held during the period, and a total of 139 species, 10 fewer than last year, were found. This was a count season of record totals for the state for a number of species. Factors contributing to this include the number of counts, the number of participants and the weather. More counts (15) were run than in any previous year, and several counts (Lake McConaughy in particular) had a much greater than average number of participants. The weather prior to the count period was mild, and most of the circles had unusually warm …

Report Of A Nesting Sora (Porzana Carolina), William M. Lemburg, Wayne J. Mollhoff

Nebraska Bird Review

During the summer of 2008, long-time NOU member and former NOU Treasurer William (Bill) Lemburg of Cairo, Howard Co., Nebraska, discovered the nest of a Sora (Porzana carolina). On 29 July 2008, while using a small flat-bottomed boat to gather duckweed (Spirodela polyrhiza) on a small pond near his bird pens to feed the exotic waterfowl he raises, he noted a pair of Sora walking about, foraging atop the dense growth of duckweed. The pair ignored his presence even though, as he later discovered, he was within 10 feet of their nest. The following evening, 30 …

Winter Field Report, December 2011 To February 2012, W. Ross Silcock

Nebraska Bird Review

The most obvious feature of this winter’s avian movements was the number of Snowy Owls, unprecedented in living memory, that invaded the state. A tally maintained by Joel Jorgensen and Lauren Dinan of Nebraska Game and Parks indicated that over 200 snowies were found in the state, and most were documented. Not as popular with the public, but perhaps of greater scientific interest were the mid-winter reports of species normally rare at this time of year. Most notable in this respect were waterfowl, grebes, cranes, and sparrows. A read-through of these species suggests the very mild winter experienced over most …

The Chicken Challenge – What Contemporary Studies Of Fowl Mean For Science And Ethics, Carolynn L. Smith, Jane Johnson

Between the Species

Studies with captive fowl have revealed that they possess greater cognitive capacities than previously thought. We now know that fowl have sophisticated cognitive and communicative skills, which had hitherto been associated only with certain primates. Several theories have been advanced to explain the evolution of such complex behavior. Central to these theories is the enlargement of the brain in species with greater mental capacities. Fowl present us with a conundrum, however, because they show the behaviors anticipated by the theories but do not have the expected changes in the brain. Consequently fowl present two challenges of interest to us here. …

Who's Afraid Of The Big Bad Cormorant?, Richard Jay King

How much do you really know about the cormorant? It's an amazing coastal bird, though not a very pretty one. Lately it has a bad rap as a destroyer of island ecosystems. This article talks about these avian creatures and their habits.

Mid-Contract Management Of Conservation Reserve Program Grasslands Provides Benefits For Ring-Necked Pheasant Nest And Brood Survival, Ty W. Matthews, J. Scott Taylor, Larkin A. Powell

School of Natural Resources: Faculty Publications

Conservation Reserve Program (CRP) fields may provide good habitat for nesting and brood-rearing ring-necked pheasants (Phasianus colchicus) during early stages of succession. But, the success of hens in early successional CRP, relative to late successional CRP and other grassland habitats, has yet to be evaluated. The reproductive period is especially critical for populations of pheasants, and CRP’s benefits to hens and chicks may decrease as fields age because of loss of vegetative diversity, decrease in vegetation density, and accumulation of residual litter. During 2005– 2006, we evaluated spatial and temporal variation in nest and brood survival for radio-marked hen pheasants …

Rural Inhabitant Perceptions Of Sandhill Cranes In Wintering Areas Of Northern Mexico, Ingrid Barcelo, Juan Carlos Guzmán-Aranda, Felipe Chávez-Ramírez, Larkin A. Powell

School of Natural Resources: Faculty Publications

Trends in the mid-continent population of sandhill cranes (Grus canadensis) indicate that the species is increasing. A large proportion of this population winters in northern Mexico where possible conflicts between local inhabitants and cranes can occur. We conducted interviews of 40 rural inhabitants living near wetlands used by cranes in three Mexican states. All interviewees had knowledge of cranes and were capable of describing them. The arrival of cranes affected 43% of interviewees. The negative effects were mainly destroyed crops with a subsequent diminished production. Seventy percent of those affected implemented scare tactics to deter the birds, while others (15%) …

In Ovo Serial Skeletal Muscle Diffusion Tractography Of The Developing Chick Embryo Using Dti: Feasibility And Correlation With Histology, Zien Zhou, Zachary Delproposto, Lianming Wu, Jianrong Xu, Jia Hua, Yan Zhou, Yongquan Ye, Zishu Zhang, Jiani Hu, E Mark Haacke

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Magnetic resonance imaging is a noninvasive method of evaluating embryonic development. Diffusion tensor imaging (DTI), based on the directional diffusivity of water molecules, is an established method of evaluating tissue structure. Yet embryonic motion degrades the in vivo acquisition of long-duration DTI. We used a dual-cooling technique to avoid motion artifact and aimed to investigate whether DTI can be used to monitor chick embryonic skeletal muscle development in ovo, and to investigate the correlation between quantitative DTI parameters fractional anisotropy (FA) and fiber length and quantitative histologic parameters fiber area percentage (FiberArea%) and limb length.

Genome Empowerment For The Puerto Rican Parrot – Amazona Vittata, Stephen J. O'Brien

Biology Faculty Articles

A unique community-funded project in Puerto Rico has launched whole-genome sequencing of the critically endangered Puerto Rican Parrot (Amazona vittata), with interpretation by genome bioinformaticians and students, and deposition into public online databases. This is the first article that focuses on the whole genome of a parrot species, one endemic to the USA and recently threatened with extinction. It provides invaluable conservation tools and a vivid example of hopeful prospects for future genome assessment of so many new species. It also demonstrates inventive ways for smaller institutions to contribute to a field largely considered the domain of large …

Efficacies Of Fenbendazole And Albendazole In The Treatment Of Commercial Turkeys Artificially Infected With Ascaridia Dissimilis, Jessica Perkins, Tom Yazwinski, Chris Tucker

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The goal of this research was to determine the extent of resistance that turkey roundworms, Ascaridia dissimilis, have developed to anti-parasitic chemicals used in commercial poultry operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, generally due to poor feed conversion. The infection itself is subclinical and many turkeys have a light to moderate worm burden. Since parasitisms are light, this leads to the infections being noticed only during processing. Ascaridia dissimilis infections consist of adult worms and developing larvae with the latter comprising most of the worm burden and causing the most …

Influences Of Adjacent Land-Use On Avian Community Structure In Sub-Boreal Peatlands Of The Midwest, Lucas J. Wandrie

All Graduate Theses, Dissertations, and Other Capstone Projects

Surrounding land use influences avian community structure; moreover, anthropogenic manipulation of habitat can alter bird species richness and composition. In the first chapter of my thesis work, I conducted avian surveys at 20 sub-boreal peatlands in eastern Minnesota and western Wisconsin to detect correlations between land development and bird community structure. Peatlands are wetlands that accumulate decaying organic plant material (peat) and provide valuable and diverse habitats to a variety of flora and fauna. I measured urban and cropland development at three spatial scales (500 m, 1000 m, and 2500 m radii). Effects of development on avian communities also were …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts

Research outputs 2012

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

Avian Species Abundance In Response To Recreational Trail Use, Carrie A. Wencel

Department of Environmental Studies: Undergraduate Student Theses

Studies have indicated that non-consumptive outdoor recreation may affect wildlife. Thus, as the nation increases interest in outdoor recreation, data suggests the effect on wildlife will also increase. Previous studies indicate that as disturbance to wildlife increases, both avian species richness will decrease. Knowing how to anticipate effects on native species when planning and managing recreational areas is important in order to both provide for human desires and ensure the least impact to local species diversity.

The goal of this project was to observe and compare avian species richness and diversity between selected trail sites within Shevlin Park, Bend, Oregon …
