Detection Of Feline Coronavirus In Captive Felidae In The Usa, Melissa Kennedy, S Citino, A Mcnabb, A Moffatt, K Gertz, Stephen Kania Mar 2012

Detection Of Feline Coronavirus In Captive Felidae In The Usa, Melissa Kennedy, S Citino, A Mcnabb, A Moffatt, K Gertz, Stephen Kania

Stephen A Kania

Feline coronavirus (FCoV) is an important pathogen of domestic and nondomestic Felidae. Investigation into the prevalence of FCoV in exotic Felidae has relied primarily on serology. The usefulness of genetic detection of FCoV using reverse transcription and nested polymerase chain reaction (RT/nPCR) for viral screening was investigated. Seventy-five biologic samples, primarily feces, from captive felids from 11 institutions were tested using PCR. Serum samples collected from all but 12 of these animals were tested for antibodies to type I and type II FCoV by indirect immunofluorescence. Twenty-four animals were positive using RT/nPCR for virus. Twenty-nine animals were seropositive ...


Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard Dec 2002

Nebraska's Sandhill Crane Population, Past, Present, And Future, Paul A. Johnsgard

Nebraska Bird Review

Although the spring concentrations of Sandhill Cranes in Nebraska's Platte Valley are now an avian phenomenon known nationwide, a general appreciation and inventory of this unique concentration of birds has only been attempted in the last few decades. I am often asked how long this largest of all crane concentrations has been occurring in the Platte Valley, and why it has developed only there. Here I will try to summarize the little-known history of this marvelous assemblage, but not dwell on the ecological reasons for it. The latter are now generally well understood to revolve around abundant spring food ...

Fall Field Report, August-November 2002, W. Ross Silcock

Nebraska Bird Review

A few words on documentation of sightings reported is in order. I receive many reports each season of rare or hard-to-identify birds. If they fit a pattern that has developed over the years (see "Birds of Nebraska"), I tend to accept them as correct. However, if they fall outside the range of prior reports, I usually email the observer and ask for some details about the identification and circumstances of the sighting. Everyone has been very nice about this process; observers sometimes take these requests as a questioning of their ability, but I haven't run into this problem with ...

Evolution Of Lake Malawi Cichlid Fishes (Perciformes: Teleostei), Peter F. Smith Dec 2002

Evolution Of Lake Malawi Cichlid Fishes (Perciformes: Teleostei), Peter F. Smith

Electronic Theses and Dissertations

The cichlid fish species flocks of East Africa provide a compelling model system in which to study the process of speciation. In Lake Malawi, greater than 1000 species of cichlids have emerged since the filling of the lake basin about 1 million years ago. Over 99% of the Lake Malawi haplochromine cichlids are endemic, suggesting that most of this diversification has taken place within the temporal and spatial boundaries set by the Lake's shores. Moreover, many of these species are endemic to small areas within the lake, indicating that speciation has occurred very recently or perhaps is in progress ...


Systematics Of The Cumacea (Crustacea), Pilar A. Haye Dec 2002

Systematics Of The Cumacea (Crustacea), Pilar A. Haye

Electronic Theses and Dissertations

Cumaceans are small benthic crustaceans. They have a marine cosmopolitan distribution with diversity increasing with depth. There are approximately 1,400 described species of cumaceans. Despite the fact that they offer a good model for the study of morphological evolution and biogeography, the studies on the Order Cumacea are almost restricted to work at the alpha taxonomy level. This thesis contributes to the systematics of Cumacea. The phylogenetic relationships within the Cumacea were studied using newly obtained partial amino acid sequences from the mitochondria1 gene Cytochrome Oxidase I. Among other findings, phylogenetic analyses revealed that the families Bodotriidae, Leuconidae, and ...


Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe Nov 2002

Individual, Temporal, And Seasonal Variation In Sperm Concentration In Tree Swallows, Michael P. Lombardo, Armetris N. Forman, Matthew R. Czarnowski, Patrick A. Thorpe

Peer Reviewed Publications

We determined sperm concentrations in Tree Swallows (Tachycineta bicolor) by manually expressing semen samples from males during prelaying, egg-laying, incubation, and nestling periods. Sperm concentrations varied by orders of magnitude (0-109 sperm mL-1) among males. Sperm concentrations were highest during the incubation period and lowest during the prelaying period. None of the samples collected during the prelaying, egg-laying, and incubation periods were devoid of sperm. In contrast, 45% of samples collected during the nestling period lacked sperm. Sperm concentrations (1) did not vary over the course of the morning during prelaying, egg-laying, and incubation periods but significantly increased ...

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie Sep 2002

Hermit Warbler In Knox County: First Accepted Record For Nebraska, Mark A. Brogie

Nebraska Bird Review

The 2002 Nebraska Ornithologists' Union Record Committee has reviewed the following record and accepted it as a Class III. This Knox County sighting constitutes the first confirmed record of Hermit Warbler in Nebraska.

On 15 May, 2002, while birding with Ben Brogie, we stopped at an isolated planting of mixed hardwoods and Ponderosa Pine (Pinus ponderosa) on a high hill 5.5 miles north (Road 530) of Creighton. We noticed several birds moving among the branches along the roadside and upon "spishing" for just a few seconds we attracted a female Cape May Warbler (Dendroica tigrina) and then an adult ...


The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen Sep 2002

The Changing Status Of Sandhill Crane Breeding In The Eastern Rainwater Basin, Joel G. Jorgensen

Nebraska Bird Review

Prior to extirpation as a breeder before 1 900, the Sandhill Crane (Grus canadensis) formerly bred throughout Nebraska (Bruner et al. 1 904; Ducey 1988; Sharpe et al. 2001). During the 1990s, several summer observations of Sandhill Crane in the Eastern Rainwater Basin region of south-central Nebraska suggested the probability of breeding. In 1999, I discovered direct breeding evidence at Harvard Waterfowl Production Area, Clay County. This breeding record, along with another by different observers in the same county during the same season are the first modern breeding records for Nebraska. In this note, I describe my observations, summarize all ...

Summer Field Report, June-July 2002, W. Ross Silcock Sep 2002

Summer Field Report, June-July 2002, W. Ross Silcock

Nebraska Bird Review

The big news this summer was the drought which affected most of southern and western Nebraska. Conditions were particularly severe in the southern Panhandle and in the southwest. As one observer (DP) wryly noted: "The cool, cloudy weather in the sixties this morning was a welcome contrast to the stinkin' hot dirt blowing blast furnace in the low one hundreds that was in south central Nebraska Sunday afternoon [June 3]." Some comments from western Kansas by birder-rancher Scott Seltman are pertinent: "I think there's no question that because of the ongoing drought most farmers delayed their fieldwork this spring ...

Summer Field Report Last Page September 2002

Nebraska Bird Review

White-winged Crossbill: The remarkable winter influx persisted into the summer period, with one seen in Omaha- the last at the observer's feeders- on 1 June (NR), and a female identified as late as 20 June at a Bassett feeder where none had showed since 9 June (CH). These sightings signify record late spring dates (although there are a few isolated summer records); both locations had hosted significant wintering flocks.

2002 (12th) Report Of The Nou Records Committee, Joel G. Jorgensen

Nebraska Bird Review

The functions and methods of the NOU Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1988 (NOU Records Committee 1988) and has been appended eleven times (Mollhoff 1989, Grenon 1990, Grenon 1991, Gubanyi 1996a, Gubanyi 1996b, Gubanyi 1996c, Brogie 1997, Brogie 1998, Brogie 1999). An update of the OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1997 ...

Spring Field Report, March-May 2002, W. Ross Silcock Jun 2002

Spring Field Report, March-May 2002, W. Ross Silcock

Nebraska Bird Review

A significant feature of this report is the fact that 94 observers provided data! E-mail has certainly provided a simple way to report sightings with ease, obviating for many the tedium of compiling a magnum opus four times a year (although the ultra-dedicated Harding and Randolph still filed their standard 40-pager!).

Interesting banding information was, provided for Red-eyed Vireo, Gray Catbird, and Pine Siskin by Ruth Green. The characteristics of the subspecies of Pine Siskin are not well-known anywhere, let alone in Nebraska.

Waterfowl and raptors had few significant sightings, although harriers were noted nesting at a couple of locations ...

Unnamed, David Wyatt Jun 2002

Unnamed, David Wyatt

Nebraska Bird Review

"Unnamed"

A yellow and black bird came to the apricot tree
this morning. I'd not seen it
before, in any of the yards here. I expect
to see such birds in the eastern woods,
not in these relatively arid tracts.

I couldn't identify it. Grosbeak? I had
no Guide, only gloomy thoughts
of no specific origin.

The bird stayed for no more than seconds.
It had a chunk of black on its throat,
like a thumbprint. Its wings never
were quiet.

Then it flew off, shrieking,
and the branch it was perched on joined
the swaying of the ...


Research Protocol For The Atlantic Bottlenose Dolphin (Tursiops Truncatus): Mirage Click Collection Study, Adrienne M. Cardwell May 2002

Research Protocol For The Atlantic Bottlenose Dolphin (Tursiops Truncatus): Mirage Click Collection Study, Adrienne M. Cardwell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Past research on dolphin echolocation has shown that dolphins can adaptively control the frequency and amplitude of echolocation clicks. The degree to which click production is controlled and the relationship between click variation and echolocation task remains uncertain. This thesis describes a research protocol for studying the adaptive control of dolphin echolocation. The protocol builds on past studies to investigate the manner in which the spectral characteristics of clicks and the overall number of clicks produce for a given task vary in relation to the type of task being performed.


Movements And Home Ranges Of San Joaquin Kit Foxes (Vulpes Macrotis Mutica) Relative To Oil-Field Development, Bruce W. Zoellick, Charles E. Harris, Brian T. Kelly, Thomas P. O'Farrell, Thomas T. Kato, Marni E. Koopman May 2002

Movements And Home Ranges Of San Joaquin Kit Foxes (Vulpes Macrotis Mutica) Relative To Oil-Field Development, Bruce W. Zoellick, Charles E. Harris, Brian T. Kelly, Thomas P. O'Farrell, Thomas T. Kato, Marni E. Koopman

Western North American Naturalist

We examined the effect of oil-field development on movements and patterns of spatial use of San Joaquin kit foxes (Vulpes macrotis mutica) on the Naval Petroleum Reserves in California (NPRC) in the San Joaquin Valley. To do this, we compared movements and home ranges of kit foxes from June 1984 to September 1985 in areas developed for petroleum production (30% of native habitat lost to production facilities) and areas with little development (3%). Distances traveled nightly by kit foxes did not differ between levels of petroleum development or between sexes (P > 0.2). Mean length of nightly movements during breeding ...
