Bird Excluding Technique, Ron J. Johnson

School of Natural Resources: Faculty Publications

To provide access to a bird feeder to desirable species while excluding House Sparrows (Passer domesticus), a loop is mounted above the feeder and extends outwardly a few inches. The excluder is fastened to the bird feeder by staples or adhesives.

Nonfederal Automated Weather Stations And Networks In The United States And Canada: A Preliminary Survey*, Steven J. Meyer, Kenneth G. Hubbard Jan 1992

Nonfederal Automated Weather Stations And Networks In The United States And Canada: A Preliminary Survey*, Steven J. Meyer, Kenneth G. Hubbard

School of Natural Resources: Faculty Publications

Not all weather data are collected by federal agencies. Fueled by the need for more specific meteorological data in real or near-real-time, the number of automated weather stations (AWSs) and AWS networks has expanded to the state and private sector over the past decade. This study employed a survey to determine the spatial extent and disposition of these nonfederal AWSs and AWS networks in the United States and Canada, the type of measurements taken, the operating procedures (i.e., maintenance and data-retrieval techniques), and the uses of the data (e.g., research, public service, agency needs). The rapid growth and expansion in …

Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown Jan 1992

Ectoparasitism As A Cause Of Natal Dispersal In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Nestling Cliff Swallows (Hirundo pyrrhonota) in southwestern Nebraska that were relatively heavily parasitized by hematophagous fleas (Ceratophyllus celsus) and swallow bugs (Oeciacus vicarius) dispersed to nonnatal colonies to breed the subsequent year, whereas nestlings that were relatively lightly parasitized returned to their natal colony to breed. There were no significant differences between dispersers and nondispersers in natal clutch size, natal brood size, relative hatching date, natal body mass, natal nest's distance from the colony's center, and natal nest's age. There were no sex differences in dispersal tendencies. Dispersing birds tended to move to smaller colonies …

Photoperiod Control Of Poplar Bark Storage Protein Accumulation, Gary D. Coleman, Tony H.H. Chen, Stephen G. Ernst, Leslie Fuchigami Jan 1991

Photoperiod Control Of Poplar Bark Storage Protein Accumulation, Gary D. Coleman, Tony H.H. Chen, Stephen G. Ernst, Leslie Fuchigami

School of Natural Resources: Faculty Publications

Bark storage proteins (BSPs) accumulate in the inner bark parenchyma of many woody plants during autumn and winter. We investigated the effect of a short-day (SD) photoperiod on the accumulation of the 32-kilodalton bark storage protein of poplar (Populus deltoides Bart. ex Marsh.) under controlled environmental and natural growing conditions. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and protein gel blot analysis revealed that 10 days of SD exposure (8 hours of light) resulted in a 20% increase in the relative abundance of the 32-kilodalton bark storage protein of poplar. After 17 days of SD exposure, the 32-kilodalton bark storage protein …


The Pacific/ North American Teleconnection Pattern And United States Climate. Part I: Regional Temperature And Precipitation Associations, Daniel J. Leathers, Brent Yarnal, Michael A. Palecki Nov 1990

The Pacific/ North American Teleconnection Pattern And United States Climate. Part I: Regional Temperature And Precipitation Associations, Daniel J. Leathers, Brent Yarnal, Michael A. Palecki

School of Natural Resources: Faculty Publications

The Pacific/ North American (PNA) teleconnection index, a measure of the strength and phase of the PNA teleconnection pattern, is related to the variations of the surface climate of the United States from 1947 through 1982 for the autumn, winter, and spring months when the PNA is a main mode of Northern Hemisphere mid-tropospheric variability. The results demonstrate that the PNA index is highly correlated with both regional temperature and precipitation. The strongest, most extensive correlations between the index and temperature are observed in winter, but large areas of the country show important associations during the spring and autumn as …


Regional Climate Centers: New Institutions For Climate Service And Climate- Impact Research, Stanley A. Changnon, Peter J. Lamb, Kenneth G. Hubbard Apr 1990

Regional Climate Centers: New Institutions For Climate Service And Climate- Impact Research, Stanley A. Changnon, Peter J. Lamb, Kenneth G. Hubbard

School of Natural Resources: Faculty Publications

In response to the need climate services at the local, state, and regional levels, a national network of regional climate centers has developed. This provides the background to this development, and outlines the functions of the centers and identifies their benefits and beneficiaries. The centers are a source of climate expertise and maintain multifaceted interfaces with the public and private sectors. Each center a) performs services, including the management of the basic data for its region and the delivery of specialized products; b) conducts applied climate studies, including the monitoring of anomalous conditions and the promotin of regional research; and …
