Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko
Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko
School of Natural Resources: Dissertations, Theses, and Student Research
Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …
The Birds Of Nebraska, Paul Johnsgard
The Birds Of Nebraska, Paul Johnsgard
Zea E-Books Collection
This annotated list of the birds of Nebraska grew gradually out of research associated with my writing of the Birds of the Great Plains: Breeding Species and Their Distribution (Johnsgard, 1979a). It expands and updates an earlier version that was published in 2013 by the University of Nebraska–Lincoln Libraries DigitalCommons’ Zea Books (Johnsgard, 2013a). It has been updated and modified in its current revision to conform with the most recent (2017) major revision of the American Ornithologists’ Society’s Checklist of North American Birds (Chesser et al., 2017). It has also been modified in its current revision to conform very closely …
Assessing Landscape Constraints On Species Abundance: Does The Neighborhood Limit Species Response To Local Habitat Conservation Programs?, Christopher F. Jorgensen, Larkin A. Powell, Jeffrey J. Lusk, Andrew A. Bishop, Joseph J. Fontaine
Assessing Landscape Constraints On Species Abundance: Does The Neighborhood Limit Species Response To Local Habitat Conservation Programs?, Christopher F. Jorgensen, Larkin A. Powell, Jeffrey J. Lusk, Andrew A. Bishop, Joseph J. Fontaine
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Landscapes in agricultural systems continue to undergo significant change, and the loss of biodiversity is an ever-increasing threat. Although habitat restoration is beneficial, management actions do not always result in the desired outcome. Managers must understand why management actions fail; yet, past studies have focused on assessing habitat attributes at a single spatial scale, and often fail to consider the importance of ecological mechanisms that act across spatial scales. We located survey sites across southern Nebraska, USA and conducted point counts to estimate Ring-necked Pheasant abundance, an economically important species to the region, while simultaneously quantifying landscape effects using a …
The Birds Of Nebraska, Revised Edition 2013, Paul A. Johnsgard
The Birds Of Nebraska, Revised Edition 2013, Paul A. Johnsgard
Zea E-Books Collection
This summary of the birds of Nebraska has been restricted to those species that have been convincingly reported at least once in Nebraska from historic time to the present. It has also been modified in its current revision to conform very closely in that regard to the most recent Nebraska Ornithologists’ Union’s “Official List of the Birds of Nebraska” (Brogie, 2010; NOU Records Committee, 2011 and annual updates). The N.O.U.’s official state list of birds (455 species as of 2013, including 329 “regular” species, 42 of “casual” occurrence, 68 accidentals, and six extinct or extirpated species) is based on actual …
A Nebraska Bird-Finding Guide, Paul A. Johnsgard
A Nebraska Bird-Finding Guide, Paul A. Johnsgard
Zea E-Books Collection
Nebraska lies in the transition zone between North American eastern and western avifaunas and is home to more than 200 breeding and 150 migrant species. This definitive guide to Nebraska birdwatching by the state’s preeminent ornithologist includes a county-by-county rundown of the best sites, a calendar of migrations, an annotated checklist of regularly occurring Nebraska birds, and recommendations for optical equipment, publications and reference materials, and contact information for conservation and ornithological groups. It features 48 maps as well as photographs and drawings by the author.
Paul Johnsgard, Foundation Professor Emeritus of Biological Sciences at the University of Nebraska–Lincoln, is …

Describes an experiment to try to hatch 16 prairie chicken eggs. Harold "Bus" Milton Malicky, Burwell, Nebraska, May 1958.
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Every producer knows that heat is harmful to the quality of eggs, and that the first step in holding fine egg quality is prompt removal of the animal heat. The Nebraska egg cooler has been developed for this purpose. Construction costs are moderate, and repeated observations demonstrate the effectiveness of the principle. Its basic factor is the temperature-reducing effect of cool, humid air passing over the eggs, as soon as possible after they are gathered.

Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley
Nebraska Agricultural Experiment Station: Historical Circulars
Eggs are one of the products which Nebraska farm families exchange for the necessities and comforts of life. Although values are measured in dollars and cents, the interest of the producers centers in the amount of useful goods and services that the eggs will buy rather than in the price per dozen or per case. Farmers are interested in a fair exchange value because they wish better homes, better schools, better churches, and better communities in general. In the typical Nebraska community, not only farmers but physicians, merchants, mechanics and school teachers are dependent for their income, either directly or …
