First Nebraska Record For The Royal Tern (Sterna Maxima) And A Review Of Regional Records, Sarah E. Rehme, Thomas E. Labedz, Janis Paseka

Nebraska Bird Review

On the afternoon of 8 Sept 2007, Don and Janis Paseka discovered a large tern on the causeway that separates Lake North from Lake Babcock, north of Columbus, Platte County, Nebraska. The causeway consists of a road next to Lake North and a low cement wall next to Lake Babcock. They observed the tern at approximately 1630 CDT standing on the low wall, on the west side of the causeway. The tern remained standing on the wall as they drove to within 15 feet and photographed it. The tern was standing with its wings drooping (Photo 1), and the fact …

2007–2008 Christmas Bird Counts In Nebraska

Nebraska Bird Review

The 2007-08 Christmas Bird Count (CBC) period will be remembered for snow cover and cold temperatures. More counts than usual were postponed due to weather. The average high temperature on count day this year was 28°F and the low was 12°F, both of which are 5-10° colder than any count day average since 2000-01. Only three counts made it above freezing during the course of the day. Snow was also a problem, and although only two circles recorded precipitation on the day of the count, snow cover and ice from earlier storms resulted in stuck vehicles, arduous walking, and inaccessible …

A Synaptic Basis For Auditory-Vocal Integration In The Songbird, Eric E. Bauer, Melissa J. Coleman, Todd F. Roberts, Arani Roy, Jonathan F. Prather, Richard Mooney

WM Keck Science Faculty Papers

Songbirds learn to sing by memorizing a tutor song that they then vocally mimic using auditory feedback. This developmental sequence suggests that brain areas that encode auditory memories communicate with brain areas for learned vocal control. In the songbird, the secondary auditory telencephalic region caudal mesopallium (CM) contains neurons that encode aspects of auditory experience. We investigated whether CM is an important source of auditory input to two sensorimotor structures implicated in singing, the telencephalic song nucleus interface (NIf) and HVC. We used reversible inactivation methods to show that activity in CM is necessary for much of the auditory-evoked activity …

A Spatial Sirs Boolean Network Model For The Spread Of H5n1 Avian Influenza Virus Among Poultry Farms, Alexander Kasyanov, Leona Kirkland, Mihaela Teodora Matache

Mathematics Faculty Proceedings & Presentations

To predict the spread of Avian Influenza we propose a synchronous Susceptible-Infected-Recovered-Susceptible (SIRS) Boolean network of poultry farms, using probabilistic Boolean rules. Gravity models from transportation theory are used for the probability of infection of a node in one time step, taking into account farm sizes, distances be- tween farms, and mean distance travelled by birds. Basic reproduction numbers are computed analytically and numerically. The dynamics of the network are analyzed and various statistics considered such as number of infected nodes or time until eradication of the epidemic. We conclude that mostly when large farms (eventually) become infected the epidemic …

En la presente investigación se evaluó un sistema integrado de control biológico de moscas mediante el uso de la avispa Spalangia Cameroni. El trabajo se desarrolló en la Granja Avícola Zamira, la cual cuenta con dos galpones, cada uno de los cuales contiene aproximadamente 11.000 aves de postura. En uno de los galpones se aplicó el experimento y en el otro se continuó con las actividades tradicionales de control de la mosca mediante fumigaciones. En un primer momento se hizo el reconocimiento de las especies de moscas y la densidad poblacional de las moscas presentes mediante la captura por trampeo …

Experimental Inoculation Of House Sparrows (Passer Domesticus) With Buggy Creek Virus, Kathryn P. Huyvaert, Amy T. Moore, Nicholas A. Panella, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

School of Natural Resources: Faculty Publications

We performed experimental inoculations of house sparrows (Passer domesticus) with Buggy Creek virus (BCRV), a poorly known alphavirus (Togaviridae) vectored primarily by the swallow bug (Hemiptera: Cimicidae: Oeciacus vicarius) that is an ectoparasite of the cliff swallow (Petrochelidon pyrrhonota) and house sparrow. Viremias were detected by plaque assay in two of six birds on days 1–3 postinoculation; viremia was highest on day 2. Viral RNA was detected by reverse transcriptase-polymerase chain reaction (RT-PCR) in blood of six of 12 birds ranging from day 1 to day 15 postinoculation. Infectious BCRV was detected in …

Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim

Theses: Doctorates and Masters

Conservation planning for animal species inhabiting modified landscapes requires understanding of where animals occur and how they utilise both natural and modified habitats. In this study the distribution and foraging behaviour of the forest red-tailed cockatoo (Calyptorhynchus banksii naso), Baudin’s cockatoo (C. baudinii) and Carnaby’s cockatoo (C. latirostris) was investigated in three study areas which each contained a different combination of modified habitats. Pickering Brook contained native forest and orchards, Wungong contained a mosaic of native forest and revegetation, while Karnet contained primarily native forest and paddocks. The relationship between cockatoo distribution and land use types was examined by constructing …
