Physiological Importance Of 1,25(Oh)2D3 Membrane-Initiated And Nuclear Actions In Chickens As A Function Of Growth, And Maturation In Male And Female Chickens, Birgitta Larsson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is well established that l,25(OH)₂D₃ is a major regulator of calcium homeostasis. The steroid exerts its effects on its target organs by two mechanisms, a slow mechanism mediated by nuclear vitamin D receptors (nVDR), and a rapid mechanism mediated by the l,25(OH)₂D₃ membrane-associated rapid response steroid binding protein (l,25D₃-MARRS bp). In this dissertation, the physiological relevance of membrane initiated steroid signaling was investigated by studying the correlation of age in male and female chickens with the magnitude of responses to l,25(OH)₂D₃ in duodena from 7-, 14-, 28-, and …

2001-2002 Christmas Bird Counts

Nebraska Bird Review

A total of 12 counts are recorded on Tables Two and Three, three more than last year's effort. The Beaver Valley and Grand Island counts are run most years, but we sometimes miss receiving data from them. DeSotoBoyer is run every year but does not always get published here, perhaps because the tally is listed as an Iowa count according to the Audubon Society; however, the area covered is partially in Nebraska, and the participants are mostly Nebraska birders.

The counts reported a total of 138 species this year, up from 133 in 1999 and from 117 in 2000. Nearly …

Winter Field Report, December 2001 To February 2002, W. Ross Silcock

Nebraska Bird Review

This winter was generally mild with most parts of the state at least somewhat dry. The most interesting avian phenomena were a major incursion of White-winged Crossbills and a warm-up in late January which resulted in several waterfowl species putting in very early appearances. Because of the latter, it was difficult to assess the status (wintering or migrant) of birds reported in late January to early February from major reservoirs and waterfowl concentration spots without some information on ice conditions. Thanks to Larry Einemann, I had detailed information about ice conditions at Branched Oak L, but I would appreciate a …

Organophosphate Toxicosis In Chickens: A Case Report, Robert Hubbard, Judith England, E. Dustan Clark

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

Two cases of organophosphate toxicity were diagnosed at the University of Arkansas Poultry Science Department poultry research farm in the Spring of 2002. In both cases the birds were being treated with the organophosphate RaVap® for Northern Fowl Mites (Ornithonyssus sylvarium) infestations. A total of 61 birds died and 13 were treated successfully with atropine sulphate.

Fall Field Report, August-November 2001, W. Ross Silcock

Nebraska Bird Review

This Fall Report offers something for everybody. Leading off are significant breeding reports of Ruddy Duck in the Rainwater Basin and Snowy Plover at Lake McConaughy. As observers bird more regularly in late July to early August we are finding that many species begin to move earlier than often realized. There were many reports of birds such as failed breeders, molt migrants, and early-fledged juveniles wandering about. Some of these prove tough identification challenges, too. Early birds were mostly water-related; Eared Grebe, Red-necked Grebe, Double-crested Cormorant, and Osprey, but also Prairie Falcon in the east, and Rusty Blackbird too. Some …

A Bird On The Shoreline, Shelly Clark

Nebraska Bird Review

A Bird on the Shoreline

My daughter tells me she doesn't believe in God.

Her words pour onto the supper table like milk spilling.

In measured silence

she waits for what I will say.

The evening news mumbles in the background,

dog scratching at the door.

I look out the window to September sky opening

its dark blue skirt of night. I tell her

the Piping plovers will be leaving soon, if they haven't already.

Asking her, do you remember the first time we saw them through binoculars,

on the broad sandbar new McConaughy?

You were eight or nine.

How …

Analaysis Of Long-Eared Owl (Asio Otus) Pellets From Eastern Nebraska, Rachel D. Mahan, Emily C. Mahan, Brandon D. Sachtleben

Nebraska Bird Review

A common way to determine the food habits of an owl is to analyze prey remains found within regurgitated pellets, called "owl pellets." We collected and analyzed owl pellets found under a Long-eared Owl (Asio otus) roost in eastern Nebraska as part of two grade school science fair projects. The results are presented here to add to the knowledge about the food habits of this species in Nebraska.

Comments On Nebraska's Falconiform And Stringiform Bird Fauna, Paul A. Johnsgard

Nebraska Bird Review

Owing to a lack of long-term survey data, determining whether Nebraska's raptor numbers are stable, increasing, or decreasing is difficult. Unlike our relatively well-monitored gamebirds, no regular surveys have been performed, and raptors barely register on the state's Breeding Bird Surveys or Christmas Bird Counts, owing to their relative rarity. However, a few data-points of interest do exist, which might be worth summarizing.

In one of the first multi-year surveys of Sandhills avifauna, H. Elliott McClure (1966) summarized raptor abundance data based on three years of study in the Nebraska Sandhills (1 941-1 944). During that period, he typically drove …

As this is being written (July 2001 ), the new book Birds of Nebraska (Sharpe, Silcock, Jorgensen; University of Nebraska Press) has just been released. From now on everyone can check early and late dates and high counts as well as distribution within the state and have a much better feel for which sightings are significant. Probably the most outstanding ornithological events this spring were a few record early arrivals (Western and Clark's Grebes, Rose-breasted Grosbeak, Indigo Bunting) and a large number of "rather early" arrivals; "rather early" means not record early but right up there. There were also some …

Development Of A Bird-Avoidance Model For Naval Air Facility El Centro, California, Edward J. Zakrajsek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bird strikes (collisions between birds and aircraft) pose a significant threat to aviation safety. For example, Naval Air Facility El Centro, California, lost an F-18 jet to a bird strike in October 1995. To help combat the bird-strike threat at Naval Air Facility El Centro, I developed a bird-avoidance model as a risk-management tool for the installation. It can be used to schedule flights at NAF El Centro and its two associated practice-bombing ranges during times of low-bird activity. I calculated bird-strike risks and published them in web-page format on both the installation's server and the USGS/Utah State University, College …

Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller

Other Publications in Wildlife Management

The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvicultural practices on goshawk breeding habitat (Reynolds-1983, Bloom et al 1986, Kennedy 1989, Crocker-Bedford 1990). Current and past research efforts on the Kaibab Plateau have mapped Goshawk nesting territories and temporal change in nesting behavior and success. However, these research efforts have not determined how long-term spatial changes in land-use activities that have influenced …

First Record Of A Reddish Egret For Nebraska, Stephen J. Dinsmore

Nebraska Bird Review

On 27 September 2000, I was birding the west end of Lake McConaughy from Marina Landing. At 2:15 p.m., I noticed a few egrets farther east off Cedar Vue. By 2:30 p.m. I had arrived at Cedar Vue and began looking over the egrets. The egrets were loosely scattered in a small area with numerous Great Blue Herons, approximately 400m from the north shore of the lake. There were six egrets present--4 Great Egrets, 1 Snowy Egret, and an intermediate-sized bird that I identified as a white morph Reddish Egret. The Reddish Egret foraged for about half an hour and …
