Detection Of Feline Coronavirus Infection In Southern African Nondomestic Felids, Melissa Kennedy, Stephen Kania, E Stylianides, H Bertschinger, D Keet, M Van Vuuren Mar 2012

Detection Of Feline Coronavirus Infection In Southern African Nondomestic Felids, Melissa Kennedy, Stephen Kania, E Stylianides, H Bertschinger, D Keet, M Van Vuuren

Stephen A Kania

Feline coronavirus (FCoV) infects members of the Felidae family with results ranging from seroconversion with no disease to fatal feline infectious peritonitis (FIP). Infection of non-domestic felids with FCoV is of concern, particularly in endangered populations such as cheetahs (Acinonyx jubatus). In this investigation, we tested 342 animals in the Republic of South Africa and Namibia, including 140 animals from wild populations, for evidence of FCoV infection by serology and/or reverse transcription/nested polymerase chain reaction (RT/nPCR) on feces from 1999 through 2001. Past or current infection was evaluated. Of these, 195 animals had evidence of infection and ...

Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe Dec 2003

Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe

Peer Reviewed Publications

Most female birds have only a left ovary and associated oviduct. The entry to the oviduct is on the left side of the urodeum of the cloaca. This arrangement may favor males that mount females from the left during copulation if it results in sperm being placed closer to the opening of the oviduct. Therefore, we predicted a left-sided directional bias of cloacal contacts during House Sparrow (Passer domesticus) copulations. Cloacal contacts from the left outnumbered those from the right 74 to 25 (3:1) during 25 bouts of copulation at 11 House Sparrow nests. While this pattern suggests that ...


Another Sandhill Crane Breeding Record In The Eastern Rainwater Basin, Joel G. Jorgensen Dec 2003

Another Sandhill Crane Breeding Record In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Jorgensen (2002) recently summarized breeding-season occurrences of the Sandhill Crane (Grus canadensis) in the Eastern Rainwater Basin (eRWB). Summering birds were first detected in 1992 (The Nebraska Bird Review 60: 145). Breeding first occurred in 1994 with four additional nesting or breeding records in subsequent years. The most recent breeding records were in 1999 when breeding activity was detected at both Kissinger Basin Wildlife Management Area (WMA) (Hoffman 1999) and Harvard Waterfowl Production Area (WPA) (Silcock and Jorgensen 1999), both in Clay County. Since late 1999 the eRWB has experienced persistent drought. This has affected wetland conditions because water levels ...


Breeding Black-Necked Stilts At Funk Waterfowl Production Area, Jeff Drahota Dec 2003

Breeding Black-Necked Stilts At Funk Waterfowl Production Area, Jeff Drahota

Nebraska Bird Review

On 21 July 2003, I was mapping wetland vegetation on Funk Waterfowl Production Area (WPA), Phelps County, when I encountered two adult Black-necked Stilts and two young on the Teal Unit, NE 1/4 of Section 16, T-6-N, R-17-W. I was using an airboat to map pockets of open water throughout the WPA. When I launched the airboat on the Teal Unit, I immediately noticed an adult Black-necked Stilt flying above the small pool. While driving the perimeter of this pool, I noticed two adult Black-necked Stilts continually flying over a small point of cattails surrounded by shallow water. As ...


Fall Field Report, August-November 2003, W. Ross Silcock Dec 2003

Fall Field Report, August-November 2003, W. Ross Silcock

Nebraska Bird Review

New in this Seasonal Report, direct from the American Ornithologists' Union (along with Wilson's Snipe, Rock Pigeon, etc.), is the modified checklist order, featuring geese, swans, and ducks at the beginning, followed by gallinaceous birds, then resuming the familiar order with loons.

Perhaps the most important use for these reports, in addition to their incorporation into the Southern Great Plains Region summary in North American Birds, is the noting of significant avian events in Nebraska. Some are of obvious importance, but the meaning of others is obscure, perhaps only to be revealed as subsequent reports show a trend, or ...


Halsey Fall Field Days, Alice Kenitz Dec 2003

Halsey Fall Field Days, Alice Kenitz

Nebraska Bird Review

Forty-one NOU members and friends gathered at the 4-H Camp at Halsey in the Nebraska National Forest on September 26–28, 2003, for the annual Fall Field Days. Fall colors were beautiful and the weather was generally good except for a brisk wind on Friday and Saturday. The ongoing drought was evident in the low level of lakes and ponds, with some of the smaller bodies of water being completely dry.

Are Hummingbirds Facultatively Ammonotelic? Nitrogen Excretion And Requirements As A Function Of Body Size, T. J. Mcwhorter, D. R. Powers, Carlos Martinez Del Rio Sep 2003

Are Hummingbirds Facultatively Ammonotelic? Nitrogen Excretion And Requirements As A Function Of Body Size, T. J. Mcwhorter, D. R. Powers, Carlos Martinez Del Rio

Zoology Faculty Publications

Most birds are uricotelic. An exception to this rule may be nectar-feeding birds, which excrete significant amounts of ammonia under certain conditions. Although ammonia is toxic, because it is highly water soluble its excretion may be facilitated in animals that ingest and excrete large amounts of water. Bird-pollinated plants secrete carbohydrate- and water-rich floral nectars that contain exceedingly little protein. Thus, nectar-feeding birds are faced with the dual challenge of meeting nitrogen requirements while disposing of large amounts of water. The peculiar diet of nectar-feeding birds suggests two hypotheses: (1) these birds must have low protein requirements, and (2) when ...


Summer Field Report, June-July 2003, W. Ross Silcock Sep 2003

Summer Field Report, June-July 2003, W. Ross Silcock

Nebraska Bird Review

To begin on a sad note, I want to mention the passing of Roger Sharpe, senior author with Joel Jorgensen and me of Birds of Nebraska. Roger was great to work with, enthusiastic, and, of course, extremely knowledgeable in many areas. Joel and I both learned a lot from Roger, in different ways, not just ornithologically. We miss Roger.

This summer was, of course, hot and waterless. Any spot with water was a hotspot. Lake McConaughy, even more than usual, was worth a look, as were Sandhills ponds that generally fared well waterwise. Joel Jorgensen kept us posted on the ...

Microsatellite Dna Evidence For Gene Flow In Neotropical Lek-Mating Long-Tailed Manakins, David Mcdonald Aug 2003

Microsatellite Dna Evidence For Gene Flow In Neotropical Lek-Mating Long-Tailed Manakins, David Mcdonald

Zoology Faculty Publications

I genotyped lek-mating Long-tailed Manakins (Chiroxiphia linearis) at Monteverde and Santa Rosa, Costa Rica, 115 km apart. Cavalli-Sforza distance was 0.04, D-LR was 0.18, and R-ST and theta were both 0.02. Bayesian clustering analysis indicated that both populations were part of a single cluster rather than from distinct clusters. I present a binomial test for probability of allelic absence as a function of sample size. Genotypic likelihood tests assigned 50% of Monteverde birds to Santa Rosa, versus 26% of Santa Rosa birds to Monteverde. Two lines of evidence supported the idea of asymmetric gene flow up the ...


How Rapidly Can Maternal Behavior Affecting Primary Sex Ratio Evolve In A Reptile With Environmental Sex Determination?, Carrie L. Morjan Aug 2003

How Rapidly Can Maternal Behavior Affecting Primary Sex Ratio Evolve In A Reptile With Environmental Sex Determination?, Carrie L. Morjan

Zoology and Genetics Publications

Theoretical models identify maternal behavior as critical for the maintenance and evolution of sex ratios in organisms with environmental sex determination (ESD). Maternal choice of nest site is generally thought to respond more rapidly to sex ratio selection than environmental sensitivity of offspring sex (threshold temperatures) in reptiles with temperature‐dependent sex determination (TSD, a form of ESD). However, knowledge of the evolutionary potential for either of these traits in a field setting is limited. I developed a simulation model using local climate data and observed levels of phenotypic variation for nest‐site choice and threshold temperatures in painted turtles ...


Geographic Variation In The Morphology Of Crotalus Horridus (Serpentes: Viperidae), John Robert Allsteadt Jul 2003

Geographic Variation In The Morphology Of Crotalus Horridus (Serpentes: Viperidae), John Robert Allsteadt

Biological Sciences Theses & Dissertations

The Timber Rattlesnake (Crotalus horridus) occurs in discontinuous populations throughout the eastern and central United States. The species exhibits high levels of polymorphism in morphological traits, especially in coloration and pattern. Previous studies recognized either distinct northern and southern subspecies or three regional morphs (northern, southern, and western), but conflicting data sets and limited geographic sampling of previous studies have left the relationships among those regional variants unclear. In this study, univariate and multivariate statistics, together with a geographic information system, were used to analyze geographic variation in 36 morphological characters recorded from 2,420 specimens of C. horridus across ...

Detection Of Feline Coronavirus Infection In Southern African Nondomestic Felids, Melissa Kennedy, Stephen Kania, E Stylianides, H Bertschinger, D Keet, M Van Vuuren

Melissa A. Kennedy

Feline coronavirus (FCoV) infects members of the Felidae family with results ranging from seroconversion with no disease to fatal feline infectious peritonitis (FIP). Infection of non-domestic felids with FCoV is of concern, particularly in endangered populations such as cheetahs (Acinonyx jubatus). In this investigation, we tested 342 animals in the Republic of South Africa and Namibia, including 140 animals from wild populations, for evidence of FCoV infection by serology and/or reverse transcription/nested polymerase chain reaction (RT/nPCR) on feces from 1999 through 2001. Past or current infection was evaluated. Of these, 195 animals had evidence of infection and ...


West Indian Mammals From The Albert Schwartz Collection: Biological And Historical Information, Robert M. Timm, Hugh H. Genoways Jun 2003

West Indian Mammals From The Albert Schwartz Collection: Biological And Historical Information, Robert M. Timm, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

In the period 1954-1976, Albert Schwartz and several students working with him made extensive collections of mammals (ca. 2,000 specimens), reptiles and amphibians, birds, and butterflies in the West Indies. Schwartz's private collection of mammals from the West Indies is among the most comprehensive and important mammal collections from the region, yet much of it has never been reported in the scientific literature. Schwartz's original intent was to fully document all of the terrestrial mammals of the West Indies. In 1989, Schwartz transferred his mammal collection of some 6,500 specimens to the University of Kansas, and ...

Comparative Genome Organization Of Human, Murine, And Feline Mhc Class Ii Region, Naoya Yuhki, Thomas W. Beck, Robert M. Stephens, Yoko Nishigaki, Kymberly Newmann, Stephen J. O'Brien

Biology Faculty Articles

To study comparative molecular dynamics in the genesis of the major histocompatibility complex (MHC), we determined a complete nucleotide sequence spanning 758,291 bp of the domestic cat (Felis catus) extended and classical class II region. The feline class II MHC includes 44 genes (31 predicted to be expressed) which display DNA sequence homology and ordered gene synteny with human HLA and mouse H2, in extended class II and centromere proximal regions (DM to DO) of the classical class II region. However, remarkable genomic alterations including gene gain and loss plus size differentials of 250 kb are evident in comparisons ...


Functional Characterization Of Retina And Optic Nerve After Acute Ocular Ischemia In Rats, Sinisa D. Grozdanic, Donald S. Sakaguchi, Young H. Kwon, Randy H. Kardon, Ioana M. Sonea Jun 2003

Functional Characterization Of Retina And Optic Nerve After Acute Ocular Ischemia In Rats, Sinisa D. Grozdanic, Donald S. Sakaguchi, Young H. Kwon, Randy H. Kardon, Ioana M. Sonea

Zoology and Genetics Publications

purpose. To functionally characterize the status of the rat retina and optic nerve after acute elevation of intraocular pressure (IOP) and to determine the dynamics of the pathologic changes in the ischemic retina and optic nerve.

methods. Retinal ischemia was induced in rats by acutely increasing the IOP (110 mm Hg/60 minutes). Direct and indirect pupil light reflexes (PLRs) were recorded from the noninjured eye, and electroretinograms (flash and flicker ERG) were recorded from the injured and control eyes before and after surgery. Amplitudes and latencies were calculated for each recording session.

results. Preoperative PLRratios (indirect/direct PLR) were ...

Spring Field Report, March-May 2003, W. Ross Silcock Jun 2003

Spring Field Report, March-May 2003, W. Ross Silcock

Nebraska Bird Review

This spring was characterized by a lack of significant ornithological events, although readers will find tidbits of interest under the following species: Greater White-fronted Goose, Mandarin Duck (believe it or not), Common Merganser, Peregrine Falcon, Buff-breasted Sandpiper, Great Horned Owl, and Blue-winged Warbler. A significant concentration of warblers and flycatchers was detected at Walnut Grove Park in Omaha in late May; check the species accounts for details. The restoration of prairie grasslands at Boyer Chute NWR seems to be paying off; Henslow's Sparrows were found there this spring for the first time. There were several new high counts, with ...
