A Late Baird's Sandpiper In Keith County, Stephen J. Dinsmore

Nebraska Bird Review

On 23 December 1994, Gordon Brown and I were walking the North Platte River below Keystone Dam as part of the Lake McConaughy Christmas Bird Count (CBC). At approximately 8:30 a.m. MST, about 0.5 mi below the dam, we observed a group of 8 Killdeer and a smaller shorebird, which we immediately recognized as a "peep." We studied the bird for about 30 minutes at distances as close as 40 feet and then returned in the afternoon to photograph it. The size and black legs immediately eliminated Least Sandpiper, and the dark rump eliminated White-rumped Sandpiper. The remaining possibilities were …

Nebraska Ornithologists' Union Annual Meeting 18 May 1996, Robin Harding

The 1997 Annual Meeting will be held jointly with the South Dakota and Iowa Ornithologists' Unions in South Sioux City, NE 16-18 May.

Neal Ratzlaff, President, reported on several items. Funds are being sought to publish the Breeding Bird Atlas for Nebraska. The new NOU Field Cards of Nebraska Birds are ready for distribution. The Wildlife Diversity Funding Initiative is on hold because some companies are afraid of increasing their prices. NOU members were encouraged to urge Cabela's to support the Initiative. [See NBR 63 (3) 1995, p. 91 for details.]

A request was received from Fermata, Inc., which has …

Another Common Crane In Nebraska With A Summary Of North American Records, Gary Lingle

Nebraska Bird Review

On 30 March 1996 around 1000 h CST, Bob Janssen and Jim Williams of Minnetonka, Minnesota, discovered a Common Crane (Grus grus) feeding in corn stubble with a flock of Sandhill Cranes (Grus canadensis) in Section 34 T9R10 Hall County, Nebraska. The Commom Crane associated with the Sandhill Cranes, which were at peak numbers in the Platte River valley. Later that day, several observers, including myself, witnessed the bird in section 32 about 500 yards away, where it mingled with a few hundred Sandhill Cranes. The difficulty in seeing this bird was illustrated by the fact …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of The Chesapeake Bay : Annual Progress Report July 1995 - June 1996, Patrick J. Geer, Herbert M. Austin

Reports

Measures of juvenile abundance are presently in wide use as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of the relative interannual abundance of early juveniles (age-0) generated from scientific survey programs have been found to provide a reliable and early estimator of future year class strength (Goodyear 1985, Lipcius and Van Engel 1990). After a review of previously available indices of juvenile abundance for important fishery resource species in the Chesapeake Bay, the Chesapeake Bay Stock Assessment Committee (CBSAC), a federal/state committee sponsored and funded by the National Oceanic and Atmospheric Administration (NOAA), …

A Recent Record Of Mountain Lion In Nebraska, Hugh H. Genoways, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

On the morning of November 10, 1991, a deer hunter in the Pine Ridge area of extreme northwestern Nebraska shot a young female mountain lion (Gertzen, 1991, Omaha World-Herald, November 15, Sunrise ed. p. 17sf; Henion, 1991, Omaha World-Herald, November 15, Metro ed. p. 17). Although mountain lions (Felis concolor) were part of the original mammalian fauna of Nebraska (Jones, 1949, J. Mammal. 30: 313; 1962, Bull Univ. Nebraska State Mus. 4: 87-100; 1964, Univ. Kansas Publ., Mus. Nat. Hist. 16: 1-356), the species has been considered to be extirpated from the state. The most recent record that …

Density-Dependent Settler-Recruit-Juvenile Relationships In Blue Crabs, Aj Pile, R Lipcius, J Van Montfrans, R J. Orth

VIMS Articles

Current theory on the population dynamics of marine species with complex life history patterns posits that a suite of physical and biotic forces (e.g., habitat structure and density-dependent predation or emigration) control survival and abundance in early life history, particularly after settlement. We have conducted a long-term sampling effort accompanied by a series of field and laboratory experiments examining the joint effects of habitat type, body size, and population density upon abundance and survival of early juveniles of the blue crab, Callinectes sapidus. In addition, the chance occurrence of a tropical storm during one set of experiments provided an opportunity …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1991-1994, Micheal F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. During the 1970's, the need for a random stratified survey of the main stem Bay and tributaries was realized and subsequently implemented. This program had a very large spatial coverage in various depth strata, but was very limited in its temporal component. Sampling occurred on a semi-annual basis primarily in January and February, and again in July (Wojcik and Van Engel, 1988a.) Based on previous results …

Prediction Of Breeding Values For Tenderness Of Market Animals From Measurements On Bulls, K. L. Barkhouse, L. Dale Van Vleck, Larry V. Cundiff, M. Koohamaraie, D. D. Lunstra, J. D. Crouse

Department of Animal Science: Faculty Publications

Data were tenderness measures on steaks from 237 bulls (Group II) slaughtered after producing freezable semen and on 1,431 related steers and heifers (market animals, Group I ) from Angus, Hereford, Pinzgauer, Brahman, and Sahiwal crosses from the Germ Plasm Evaluation project at the U.S. Meat Animal Research Center. Tenderness was assessed through Warner-Bratzler Shear Force (SF), taste panel tenderness (TPT), marbling score (MS), and myofibrillar fragmentation index (MFI). For all traits, as fraction Bos indicus inheritance increased, implied tenderness decreased. Heritability estimates were generally not significantly different from zero. Genetic correlations generally indicated favorable associations among the traits. The …

Comparison Of Circulating Concentrations Of Reproductive Hormones In Boars Of Lines Selected For Size Of Testes Or Number Of Ovulations And Embryonal Survival To Concentrations In Respective Control Lines, D. V. Mariscal, P. L. Wolfe, E. G. M. Bergfeld, Andrea S. Cupp, F. N. Kojima, K. E. Fike, T. Sanchez, M. E. Wehrman, Rodger K. Johnson, Roger J. Kittok, J. J. Ford, J. E. Kinder

Department of Animal Science: Faculty Publications

The objectives of this study were to determine whether circulating concentrations of gonadotropins and gonadal hormones of boars were altered as a result of selection of pigs for size of testes or for embryonal survival and(or) number of ovulations. Included in Exp. 1 and 2 were boars with the greatest estimated paired weight of testes (TS) and boars from a control (C) line. Concentrations of FSH were similar ( P > .10) in boars from the TS and C lines. In Exp. 3, 4, and 5, circulating concentrations of FSH and 17β-estradiol (E₂) were evaluated in neonates, during pubertal …

Expression Of A Bovine Κ-Cn Cdna In The Mammary Gland Of Transgenic Mice Utilizing A Genomic Milk Protein Gene As An Expression Cassette, Alfonso Gutiérrez, Harry M. Meade, Paul Ditullio, Daniel Pollock, Merry Harvey, Rafael Jiménez-Flores, Gary B. Anderson, James D. Murray, Juan F. Medrano

Dairy Science

Transgenic mice were produced by microinjection of a DNA construct composed of the bovine κ-casein (κ-CN) cDNA under the control of the goat β-CN 5' promoter elements and 3' flanking regions into pronuclear-stage embryos. The gene construct targeted the expression of bovine κ-CN RNA to the mammary gland and secretion of bovine κ-CN in the milk. In the three lines studied (BC-7, BC-31 and BC-67) the transgene was stably integrated and propagated as a Mendelian locus. Expression of the bovine protein in lactating mice from the three transgenic lines was demonstrated by northern and western blots. In ten different tissues …

Histopathology Of The Thymus Of Coho Salmon Oncorhynchus Kisutch Experimentally Infected With Renibacterium Salmoninarum, E Flano, Sl Kaattari, B Razquin, Aj Villena

VIMS Articles

We report on the histopathological changes occurring in the thymus of coho salmon Oncorhynchus kisutch experimentally infected with Renibacterium salmoninarum. Coho salmon were intraperitoneally infected, and the thymi were collected weekly from 1 to 7 wk post-infection, and processed for ultrastructural study. The thymus appeared to be infected only in fish collected at 6 and 7 wk post-infection. The first stage of the infection was characterized by the presence of a low number of bacteria scattered in the connective tissue of the capsule. Further progression of the thymic infection was characterized by the rupture of the capsular-thymic barrier, and by …

Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The diversity of native plant species in urban environments is usually overlooked when biodiversity levels are considered. Inventories of native plants reveal many to be rare species surviving the harsh conditions encountered in urban ecosystems. Knowledge of their existence and an inventory of their distribution will assist in maintaining these populations. Protection strategies for rare plant species are outlined for urban National Parks.

Female Choice In Sage Grouse: The Roles Of Attraction And Active Comparison, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse Centrocercus urophasianus have implicated both the acoustic quality and repetition rate of the stereotyped strut display as putative cues for female choice. Stages in the choice process at which specific components of male courtship display influence female decisions were investigated using field observations of female premating behavior. Females visited a subset of territorial males and then actively chose one of these as a mate. The order in which males were visited suggested that females searched until an acceptable mate was found, rather than employing a “best-of-n” tactic. Numbers of females visiting a …
