Eurasian Wigeon In Sarpy County, Nebraska, Mark Brogie
Eurasian Wigeon In Sarpy County, Nebraska, Mark Brogie
Nebraska Bird Review
On Saturday 14 May 2011 on the Sarpy County Spring Count, Justin Rink, Jim Ducey, Ellen Brogie, and I found a Eurasian Wigeon at LaPlatte Bottoms. When first discovered the bird was in the company of multiple Gadwall and at least one adult male American Wigeon. The bird was a striking adult male bird with a rusty red head and a yellowish forehead. The breast was reddish and contrasted with the gray back and sides. This coloration made the white wing stripe more pronounced than that of the American Wigeon. The bird showed no evidence of hybridization. Multiple observers viewed …
Assessing The Stability, Biological Transfer And Developmental Impact Of Environmentally Relevant Nitrosamines Using A Chicken Egg Model, Nikita Joshi
Environmental Health, Occupational Health, and Toxicology: Dissertations and Student Research
Nitrosamines comprise a large group of potentially toxic compounds occurring in the environment as by-products of various manufacturing, agricultural and natural processes. Nitrosamines are produced from reaction of nitrite with a suitable secondary amine in an acidic matrix; these acidic conditions can occur in environmental media and in the mammalian gastrointestinal (GI) tract. This research focused on the stability, transfer, and impacts of the environmentally relevant nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosmorpholine (NMOR), and N-nitrosoatrazine (NNAT) (formed from reaction of nitrite with dimethylamine, morpholine, and atrazine), using the chicken egg and embryo model systems. Chicken eggs were used to …
An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes
An Ecological Study Of Peregrine Falcons (Falco Peregrinus) At Lake Mead National Recreation Area, 2006-2010, Joseph Graham Barnes
UNLV Theses, Dissertations, Professional Papers, and Capstones
Peregrine Falcons (Falco peregrinus) represent an encouraging conservation biology success story in North America during the twentieth century. Their distribution and population size suffered major restrictions after the initiation of widespread application of the synthetic pesticide dichloro-diphenyl-trichloroethane (DDT) within the U.S. in the 1940s. The species was federally listed as endangered in the U.S. in 1969 and was then delisted in 1999 after DDT was banned in 1972. Herein, I present my ecological research of peregrines within Lake Mead National Recreation Area (LMNRA), concentrating on the years 2006-2010. This thesis is comprised of two chapters. In the first chapter, I …

Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds
Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds
Master's Theses
Arginine transport is primarily mediated by the cationic amino acid transporters (CATs) in mammalian cells, but in aves the y+, b0,+ and B0,+ transport systems have also been observed. Arginine is the limiting catabolic substrate required for the production of nitric oxide (NO), a highly reactive compound that acts as a signaling molecule or killing compound. NO is synthesized by inducible nitric oxide synthase (iNOS) by macrophages for pathogen clearance. In mammals, CAT-2B is responsible for ARG import in the macrophage for NO synthesis, but the chicken CAT-2B isoform does not transport ARG. Therefore the objective …
Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen
Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …
A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps
A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps
Nebraska Bird Review
The breeding range of the Summer Tanager (Piranga rubra) is well documented and expands across the southern U.S. extending northward to New Jersey and west along and south of the Great Lakes to the eastern edge of the Great Plains (Terres 1991; Robinson 1996). In Nebraska the species is generally confined to the Lower Missouri and Platte River Valleys where it occurs locally (Sharpe et al. 2001). Because the species exists in relatively low numbers across southeastern Nebraska, there are few breeding and nesting records for the state. Fewer than 10 breeding records, including one historical account have …

Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock
Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock
Nebraska Bird Review
Nebraska birders might remember seeing reports posted to NEBirds a few years back by Cole Wild, a native Coloradan whose mother's family is from Nebraska. Cole took up birding at age 19, spurred by an earlier high school environmental science class that required identification of 100 species of birds. As with many of us, a brightly plumaged bird, in this case a Western Tanager, resulted in "the birdwatching gene" in Cole suddenly being "switched to the ON position." Soon after, Cole went on a "what the heck, I'll try it" field trip to see a Kelp Gull at Loveland Reservoir …
2010–2011 Christmas Bird Counts, Don Paseka
2010–2011 Christmas Bird Counts, Don Paseka
Nebraska Bird Review
Fourteen Christmas Bird Counts were held in Nebraska in the 2010–2011 season. The Branched Oak–Seward count was canceled due to weather, but in comparison to last year, the weather was generally dry, mild, and cooperative. Even though open water was limited, the species associated with water were well represented, resulting in the highest total number of species (149) ever, easily topping the previous high count of 138 in 2001. In all, 17 species set new high counts, 5 tied previous highs, and the amazing Brown-headed Nuthatches stayed in Lincoln and were counted for the first time in Nebraska.
Twelve species …
Winter Field Report, December 2010 To February 2011, W. Ross Silcock
Winter Field Report, December 2010 To February 2011, W. Ross Silcock
Nebraska Bird Review
This winter was pretty much a rerun of last, although perhaps not as severe; I could have used last winter's Introduction again. If there was an overall theme, it would be the widespread occurrences of species that would not be expected to linger into late December and January. Several species of waterbirds, notably Blue-winged Teal, scoters, Ruddy Duck, Common Loon, and Homed and Red-necked Grebes were in this category. Large numbers of Western Grebes were still at Lake McConaughy in early January, and surprisingly late individuals of Black-crowned Night-Heron and Plegadis ibis were located. Mourning Doves were in good numbers …

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda
Nebraska Bird Review
Don and Lillian Stokes are well known for their nature guides that cover a variety of subjects, from hummingbirds and beginner shorebird identification to reptiles and amphibians. Their original pair of Stokes Field Guide to Birds: Eastern Region and Western Region have remained popular among North American birders since their appearance in 1995. They were illustrated with photographs instead of the traditional paintings used in most field guides. The authors' latest book, The Stokes Guide to Birds of North America is essentially an entirely new and much improved version of these two guides. Instead of being split into two books, …

Abstract
Background
Microinversions are cytologically undetectable inversions of DNA sequences that accumulate slowly in genomes. Like many other rare genomic changes (RGCs), microinversions are thought to be virtually homoplasy-free evolutionary characters, suggesting that they may be very useful for difficult phylogenetic problems such as the avian tree of life. However, few detailed surveys of these genomic rearrangements have been conducted, making it difficult to assess this hypothesis or understand the impact of microinversions upon genome evolution.
Results
We surveyed non-coding sequence data from a recent avian phylogenetic study and found substantially more microinversions than expected based upon prior information about …
Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Inquiry: The University of Arkansas Undergraduate Research Journal
Our multidisciplinary group at the University of Arkansas has been investigating the suitability of the chicken as a medical model for pulmonary arterial hypertension (PAH) in humans. There are several forms of PAH in humans arising from elevated pulmonary arterial pressure and pulmonary vascular resistance. Spontaneous cases of PAH are known as idiopathic PAH (IPAH), where the exact physiological causes are not known. IPAH patients that do not respond to standard treatments have a prognosis of only a few years. Currently, there is no acceptable animal model for IPAH. As part of our effort to pursue the chicken as model …
Postfledging Survival And Habitat Use Of Spotted Towhees (Pipilo Maculatus) In An Urban Park, Amy Ann Shipley
Postfledging Survival And Habitat Use Of Spotted Towhees (Pipilo Maculatus) In An Urban Park, Amy Ann Shipley
Dissertations and Theses
Habitat fragmentation, and the resulting increase in edge habitat, has important effects on birds, including the increased probability of nest predation, changes in habitat structure, and the increased presence of non-native plant species. It is critical to understand the effects of fragmentation at all stages of the avian life cycle, including the often overlooked postfledging period. Because much of juvenile mortality occurs during the immediate postfledging period, and juvenile mortality contributes substantially to population dynamics, it is necessary to understand if fledgling survival is reduced in edge habitats and if fledglings' survival is influenced by their habitat use. During 2008 …

Use Of Nape Tags For Marking Offspring Of Precocial Waterbirds, Todd W. Arnold, Daizaburo Shizuka, Bruce E. Lyon, Jeffrey T. Pelayo, Katherine R. Mehl, Joshua J. Traylor, Wendy L. Reed, Courtney L. Amundson
Papers in Ornithology
Individualized markers that allow organisms to be identified without recapture are invaluable for studies of survival, movement, and behavior. Nape tags consisting of brass safety pins with unique combinations of two or three colored plastic beads were used to mark 5,868 American Coot (Fulica americana) chicks and 331 Ruddy Duck (Oxyura jamaicensis), 157 King Eider (Somateria spectabilis) and 664 White-winged Scoter (Melanitta fusca deglandi) ducklings. These markers allowed for documentation of parent-offspring interactions, post-hatching survival, brood movements and brood-mixing behaviors. Nape tags were inexpensive, easy to make, easy to observe with binoculars …
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
All Graduate Theses, Dissertations, and Other Capstone Projects
Invasive plants are a primary contributor to loss of biodiversity worldwide. In southern Minnesota, many wetlands have been invaded by reed canarygrass (Phalaris arundinacea). The current perception among ecologists and resource managers is that these wetlands are of little value to wildlife, yet little is known about the effects on birds of the widespread conversion of diverse wetlands to apparent monocultures of P. arundinacea. The purpose of this study was to determine the effects of P. arundinaceamediated changes in the wetland plant community on avian communities and nesting success. During 2006 and 2007, I studied four diverse sedge wetlands paired …
Analysis Of The Genetic Structure Of Bithynia Tentaculata Snail Populations In Wisconsin And Minnesota, Sarah J. Whalen
Analysis Of The Genetic Structure Of Bithynia Tentaculata Snail Populations In Wisconsin And Minnesota, Sarah J. Whalen
All Graduate Theses, Dissertations, and Other Capstone Projects
In recent years, there have been tens of thousands of waterfowl mortalities in Wisconsin and Minnesota. An invasive species of snail, Bithynia tentaculata, is a host for the trematode parasites (Cyathocotyle bushiensis and Sphaeridiotrema globulus) that have caused these deaths. A microsatellite-enriched genomic library was detected using DNA from a B. tentaculata specimen from Lake Onalaska (Pool 7 of the Upper Mississippi River). Seven polymorphic microsatellite loci were used to genotype snails collected from Lake Butte des Morts, Shawano Lake, and Lake Onalaska in Wisconsin, as well as Lake Winnibigoshish in Minnesota. The genetic diversity of each population was measured …
