The 2002 Nebraska Nest Report, Wayne Mollhoff Dec 2004

The 2002 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry ...

Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton Dec 2004

Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton

Nebraska Bird Review

Since 1992 the Central Nebraska Public Power and Irrigation District (Central) has protected and monitored nesting Piping Plovers along the shore of Lake McConaughy (Keith County, Nebraska). Over those 13 seasons, Central monitored 849 Piping Plover nests and documented the successful fledging (successful fledging is defined as a chick at least 24 days old, or one observed flying) of 1,237 Piping Plover chicks (Table 1), making Lake McConaughy one of the most productive nesting areas for Piping Plovers in Nebraska. The following is a documentation of the contributions of Lake McConaughy to the recovery goals for Piping Plovers in ...


Fall Field Report, August-November 2004, W. Ross Silcock Dec 2004

Fall Field Report, August-November 2004, W. Ross Silcock

Nebraska Bird Review

The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.

Counts of interest were 3000 Double-crested ...


Does Birding Have A Future?, Rick Wright Dec 2004

Does Birding Have A Future?, Rick Wright

Nebraska Bird Review

Does birding have a future?

Now this might seem an odd question, even an absurd question, to pose to an audience like this, and the answer might seem obvious. How could birding not have a future when we, all of us, are birders who bird, and when survey after recent survey assures us that our numbers are growing, our diversity increasing, and our economic and ethical contributions to American society ever more conspicuous. Does birding have a future? The simple answer is yes.

That's the simple answer. The more interesting answer is yes-yes, but. Yes, birding has a future ...

Follicular Development And Maturation In Gilts Selected For An Index Of High Ovulation Rate And High Prenatal Survival, H.-W. Yen, J. J. Ford, D. R. Zimmerman, R. K. Johnson Nov 2004

Follicular Development And Maturation In Gilts Selected For An Index Of High Ovulation Rate And High Prenatal Survival, H.-W. Yen, J. J. Ford, D. R. Zimmerman, R. K. Johnson

Faculty Papers and Publications in Animal Science

Seventy-one 10th-generation gilts from White Line-1 (WL-1 = randomly selected control line) and White Line-2 (WL-2 = selected for an index of ovulation rate and prenatal survival rate) were used to compare the pattern of follicular development and atresia during the follicular phase of the estrous cycle. Gilts were treated with PGF on d 13 of the estrous cycle (d 0 of induced follicular development) to induce luteolysis and assigned randomly within line and sire for ovary recovery on d 0, 2, 3, 4, 5, and the day after estrus. Ovaries were evaluated for numbers of corpora albicantia and small (2 ...

Microarray Profiling For Differential Gene Expression In Ovaries And Ovarian, A. R. Caetano, R. K. Johnson, J. J. Ford, Daniel Pomp

Faculty Papers and Publications in Animal Science

A unique index line of pigs created by long-term selection ovulates on average 6.7 more ova than its randomly selected control line. Expression profiling experiments were conducted to identify differentially expressed genes in ovarian tissues of the index and control lines during days 2–6 of the follicular phase of the estrous cycle. Fluorescently labeled cDNAs derived from ovary and follicle RNA were cohybridized on microarray slides (n = 90) containing 4608 follicle-derived probes printed in duplicate. Statistical analysis of the resulting ~1.6 million data points with a mixed-model approach identified 88 and 74 unique probes, representing 71 and ...

A Large-Sample Qtl Study In Mice: Iii. Reproduction, Joao L. Rocha, Eugene J. Eisen, Frank Siewerdt, L. Dale Van Vleck, Daniel Pomp

Faculty Papers and Publications in Animal Science

Using lines of mice having undergone long-term selection for high and low growth, a large-sample (n ≈ 1000 F2) experiment was conducted to gain further understanding of the genetic architecture of complex polygenic traits. Composite interval mapping on data from 10-week-old F2 females (n = 439) detected 15 quantitative trait loci (QTLs) on 5 chromosomes that influence reproduction traits characterized at day 16 of gestation. These QTL are broadly categorized into two groups: those where effects on the number of live fetuses (LF) were accompanied by parallel effects on the number of dead fetuses (DF), and those free of such undesirable ...

Heterosis For Grain Yield And Other Agronomic Traits In Foxtail Millet, M. M. Siles, William K. Russell, Lenis Alton Nelson, David D. Baltensperger, Blaine Johnson, L. Dale Van Vleck, Stanley G. Jensen, Gary L. Hein Oct 2004

Heterosis For Grain Yield And Other Agronomic Traits In Foxtail Millet, M. M. Siles, William K. Russell, Lenis Alton Nelson, David D. Baltensperger, Blaine Johnson, L. Dale Van Vleck, Stanley G. Jensen, Gary L. Hein

Faculty Papers and Publications in Animal Science

Foxtail millet [Setaria italica (L.) P. Beauv.] is a largely self-pollinating species that is used as a warm-season annual in the USA. Nearly all cultivars of this species grown in the USA are selections from land races. This research was undertaken to determine whether sufficient high-parent heterosis is expressed in foxtail millet for grain yield and other key traits to justify the development and use of varietal crosses. Seven diverse parents and 21 F2s and 21 F3s produced from biparental crosses were evaluated in five environments in 1996. Genotype x environment interaction was highly significant for ...

Evaluation Of Gene Expression In Pigs Selected For Enhanced Reproduction Using Differential Display Pcr And Human Microarrays: I. Ovarian Follicles, C. D. Gladney, G. R. Bertani, R. K. Johnson, Daniel Pomp

Faculty Papers and Publications in Animal Science

Differential display PCR (ddPCR) and complementary DNA microarray analyses were used to evaluate gene expression differences in porcine ovarian follicles between a line of pigs selected for an index of ovulation rate and embryo survival (Line I) and its randomly selected control line (Line C). Follicles (4.0 to 7.0 mm) were dissected from ovaries of multiparous sows (n = 27) at either 2 or 4 d following PGF2α analog injection on d 12 to 14 of the estrous cycle. Using ddPCR, differentially expressed bands (n = 282) were excised from gels and 107 were sequenced, yielding 84 unique porcine follicle ...


Comparison Of Models Including Cytoplasmic Effects For Traits Of Rambouillet Sheep, G. D. Snowder, K. J. Hanford, L. Dale Van Vleck Oct 2004

Comparison Of Models Including Cytoplasmic Effects For Traits Of Rambouillet Sheep, G. D. Snowder, K. J. Hanford, L. Dale Van Vleck

Faculty Papers and Publications in Animal Science

The objective was to determine appropriate analytical models considering cytoplasmic inheritance for birth weight (BWT, n = 35,604), weaning weight (WWT, n = 34,114), fleece weight (FWT, n = 38,113) and number born (NB, n = 39,029) for Rambouillet sheep. For BWT, models that included dam by year, dam by number born, and sire by dam effects, in addition to direct and maternal effects, were significantly better than the basic maternal effects model. For WWT, variances due to direct, maternal, and maternal permanent environmental effects (0.05 of variance) were not zero. For FWT, heritability was 0.55 for all ...

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways Oct 2004

The Florida Bonneted Bat, Eumops Floridanus (Chiroptera: Molossidae): Distribution, Morphometrics, Systematics, And Ecology, Robert M. Timm, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

A review and reappraisal of bats of the genus Eumops (Chiroptera: Molossidae) reveals that considerable geographic variation is present in the bonneted bat, E. glaucinus; it is a complex consisting of >1 species. Bonneted bats in Florida are significantly larger than those in all other populations, and have proportionally shorter and deeper basisphenoid pits, the glenoid fossa is broadly triangular with rounded apices, and bacular shape differs from that in other populations. Additionally, bonneted bats in Florida have a broader palate than bats from populations in South America. Given these differences, the correct name for both Pleistocene and Recent Florida ...


Heritability Estimates For Carcass Traits Of Cattle: A Review, Angel Rios Utrera, L. Dale Van Vleck Sep 2004

Heritability Estimates For Carcass Traits Of Cattle: A Review, Angel Rios Utrera, L. Dale Van Vleck

Faculty Papers and Publications in Animal Science

We present estimates of heritability for carcass traits of cattle published in the scientific literature. Seventy-two papers published form 1962 to 2004, which reported estimates of heritability for carcass traits, were reviewed. The unweighted means of estimates of heritability for 14 carcass traits by slaughter end point (age, weight, and fat depth) were calculated. Among the three end points, carcass weight, backfat thickness, longissimus muscle area, and marbling score were the carcass traits with the most estimates of heritability (56≤n≤66). The averages for these traits indicate that they are similarly and moderately heritable (0.40, 0.36, 0 ...

The 2001 Nebraska Nesting Report, Wayne Mollhoff Sep 2004

The 2001 Nebraska Nesting Report, Wayne Mollhoff

Nebraska Bird Review

The spring of 2001 will likely be remembered as the winter that wouldn't end, especially in central and western Nebraska. The last remnants of roadside snowbanks remained in the east until 10 April, but the last blizzard closed down the Panhandle on 21-22 April, and the last appreciable snowfall there was on 19 May. None of these dates represent late records, but are remarkably later than average for the past 10-15 years, and seemed especially burdensome following the long cold winter and the remarkably early spring the previous year.

While I recognize the danger inherent in making generalizations when ...

In Memory Of Clyde E. Johnson- September 2004

Nebraska Bird Review

Long-time NOU member Clyde Johnson passed away on May 4, 2003. He is survived by his wife Emma, who now resides in Fredericksburg, Texas.

Clyde and Emma lived in Omaha, where Clyde was employed as an insurance agent. They made numerous birding trips to Central America, Europe and Asia. Few other details of his life are available, which is quite likely just the way Clyde wanted it. Although Clyde was quiet about his personal life, he was well known among NOU members for his contributions of time, enthusiasm and money to the organization.

Birds Of Spring Creek Prairie Audubon Center - 1999-2004, Kevin Poague

Nebraska Bird Review

In the summer of 1998, Audubon Nebraska, a state office of the National Audubon Society, purchased the 610-acre O'Brien Ranch located three miles south of Denton, Nebraska. The site, now called Spring Creek Prairie Audubon Center (SCPAC), will be devoted to prairie education and restoration. The Center's size expanded to 626 acres in 2000 when the Wachiska Audubon Society bought an adjacent 16-acre property on the northwest comer of the section.

Historically, most of the ranch was never farmed, probably because of its hills and the large number of glacial boulders present in the soil. It is one ...

Nebraska Bird Review

Recently, Mr. William Lemburg of Cairo, Nebraska, in a letter to the Editor of the Nebraska Bird Review, noted the following: "I have a friend who does quite a bit of goose hunting. He remarked to me that during the spring snow goose season, he occasionally shoots an extra-large Snow. Thinking that maybe a few Greater Snows that winter along the Atlantic Coast may end up in the Central Flyway, I asked him to save the head of one if he bagged one the following season. This is about five years ago. The following season he did get one. Enclosed ...

Summer Field Report, June-July 2004, W. Ross Silcock

Nebraska Bird Review

The coverage of the state by observers who report their sightings, mostly to the listserv NEBirds, is very good relative to their rather low number. Even so, there are parts of the state that are only recently revealing their secrets. Extensive work in the Panhandle in the late 1990s, including mist-netting by Steve Dinsmore, showed that several western species are regular migrants through that part of the state, and similar extensive coverage of waterbirds and shorebirds at Lake McConaughy yielded similar valuable information, following the pioneering efforts there by Dick Rosche. This report contains many references to another interesting area ...
