Why Doesn't Such-And-Such A Game Bird Do Well In Nebraska?, Levi Mohler
Why Doesn't Such-And-Such A Game Bird Do Well In Nebraska?, Levi Mohler
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Why doesn't such-and-such game bird do well in Nebraska? This is a question which is often asked field workers for the game department. The answer to such an inquiry varies with the bird in question, but in general the following applies: Since climate, topography, and natural foods vary so much from place to place, and since most individual species are not highly adaptable, nature has through the centuries evolved many species, or kinds, of birds, each species adapted to meet certain conditions. Some of these have extensive ranges; others are limited in their distribution. The conditions suited to one species …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report represents a compilation, analysis and summarization of data collected on the South Platte Management Area and deals primarily with game bird data collected by personnel of Project W-37-R. History, general description, and methods of operation are discussed, and recommendations for future operations given.
Briefly, the South Platte Management Area is located in Logan and Sedgwick counties, comprising over 11, 400 acres of state-owned land in four separate segments. The largest segment (more than 12,000 acres of deeded and leased land) lies along the South Platte River from Proctor to Red Lion. This, and a second area of 240 …
Spring Prairie Grouse Census - 1955, Reuel Janson
Spring Prairie Grouse Census - 1955, Reuel Janson
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The 1955 spring prairie grouse census was conducted during the period March 30 to May 4. Census data were obtained by means of a survey of dancing and booming grounds on 18 automobile transects.
An average population density of 4.77 sharptailed grouse, and 0.71 prairie chickens per square mile was found. Comparable data for 1954 and 1955 indicate a 10 percent decline in the combined prairie and grouse population. The prairie chicken population declined considerably more than the sharptail population.
The extreme northern portion of the grouse range, Corson and Perkins Counties, experienced population gains of approximately 50 percent which …
Condensation Reaction Of Terephthaladehyde And Acetophenone, Lloyd J. Mitchell
Condensation Reaction Of Terephthaladehyde And Acetophenone, Lloyd J. Mitchell
University of the Pacific Theses and Dissertations
The plant pigments constitute a fascinating group of compounds whose constitution has only recently been partially clarified. Roughly speaking, there are two main groups of pigment: the plastids, associated with the protoplasmic structure of plants, and the anthocyanins, generally found in solution in the cell sap. The term “anthocyanin” is derived from the Greek, “antho” signifying flower and “cyan” meaning blue, and was introduced by the botanist Marquart in 1835 to designate the blue pigments of flowers. It has since been extended to include all of the pigments of this group, the anthocyanin pigments being responsible for the innumerable shades …
