Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Gives an overview of research in Mongolia that was conducted by botanists from the University of Halle in cooperation with their Mongolian colleagues. A summary was compiled of expeditions and related activities covering more than 40 years of cooperation between 1962 and 2006, including a list of the respective participants, the duration of travel, the areas of Mongolia visited, the main aims, and principal publications.

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …

Manual Of The Grasses Of The United States, Second Edition, A. S. Hitchcock, Agnes Chase

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

By the late A. S. HITCHCOCK (died December 16, 1935), principal botanist, Division of Plant Exploration and Introduction; second edition revised by AGNES CHASE, formerly senior botanist and later collaborator, Division of Plant Exploration and Introduction, Bureau of Plant Industry, Soils, and Agnculturat Engineering, Agricultural Research Administration, and research associate, United States National Museum, Smithsonian Institution.

Of all the plants of the earth the grasses are of the greatest use to the human race. To the grasses belong the cereals, sugarcane, sorghum, and the bamboos; and, since they furnish the bulk of the forage for domestic animals, the grasses are …

Common Native Grasses Of Nebraska, A. L. Frolik, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Circulars

Twenty-four native grasses that are the most important and most generally distributed in Nebraska are described and illustrated in this circular. Information concerning their distribution and economic value is given. Anyone interested in learning to identify the common native grasses should be able to do so by comparing plant specimens with the illustrations and descriptions herein presented. The work of identifying grasses may seem technical and limited only to botanists or those with similar training. Nearly anyone, however, can learn to identify many of the native grasses if willing to spend a little time and effort.

Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements

School of Biological Sciences: Faculty Publications

AN ILLUSTRATED GUIDE FOR PLANT-LOVERS AND PLANT-USERS WITH TWENTY-FIVE PLATES IN COLOR AND TWENTY-TWO PLATES IN BLACK AND WHITE

The present book is an endeavor to present the materials of the Rocky Mountain flora in preliminary form from the standpoint of the experimental ecologist. The latter is concerned primarily with the relationships of "species" and their subdivisions as an organic expression or measure of habitat differences, and of the competitive relations of the various formations. Whatever the taxonomic value of the numerous segregates of the last decade or two, the fact that the binomial form conceals the relationship to the …

On The Movements Of Petals, Esther Pearl Hensel

Papers from the University Studies series (University of Nebraska)

The following paper has to do with an investigation of the physical causes· which bring about opening and closing movements, periodic or otherwise, of certain flowers. With that end in view, seven different species of flowering plants have been experimented upon directly, a much larger number being simply observed with respect to the nature, time, etc., of their anthotropic movements. Movement consists in the corolla taking upon itself either the open or closed position for certain periods of the day or night; for example, the morning glory (Ipomoea purpurea) opens early in the morning (from 4:00 to 5 …

Report Of A Botanical Exploration Of The Sand-Hill Region Of Central Nebraska Made In The Summer Of 1893., Per Axel Rydberg

School of Biological Sciences: Dissertations, Theses, and Student Research

Rydberg (1860–1931) was born Sweden and emigrated to the United States in 1882, first to mining camps in upper Michigan and eventually to Wahoo, in Saunders County, Nebraska, where he taught mathematics from 1884 to 1893 at now defunct Luther Academy. In the summers of 1891-1893, 1895, and 1896 he was a field agent for the United States Department of Agriculture and collected plants in Nebraska, South Dakota, Montana, Idaho, Wyoming, and Colorado, and specimens from those and other trips are in the Bessey Herbarium at the University of Nebraska–Lincoln, which house what is now known as the Charles E. …

A Second Report Upon The Native Trees And Shrubs Of Nebraska, Charles E. Bessey, Robert Bolin , Depositor

School of Biological Sciences: Faculty Publications

Dr. Bessey was then Nebraska State Botanist and “Professor of Botany, State University, Lincoln Nebraska.” The State University is now called that University of Nebraska–Lincoln. This document was published as a contribution to the knowledge of the native woody plants of the state. Several reports had been published previously each containing additions and corrections. This report contains a “Special Request” that asked readers around the state to send samples of native trees and shrubs to the author.

The report contains a classification list of the various trees and shrubs along with information about where they can be found. A table …
