Some Ecological Notes On The Alpine Tundra In The Area Of The Juneau Ice Field, Richard T. Ward

Proceedings of the Iowa Academy of Science

During the summer of 1949 an introductory study of the vegetation of nunataks and peripheral tundra areas of the Juneau Ice Field was made. The field work constituted a part of the Juneau Ice Field Research Project, which in addition to ecology includes investigations in the fields of geology, glaciology, meteorology, seismology, and cartography. Except for a small plant collection made by a reconnaissance party in the previous summer, the vegetation of this ice field was virtually unknown, as were in fact the other scientific aspects. The expedition of 1949 was the first group to spend an entire summer on …

Recent Advances In Veterinary Entomology1, A.W. Lindquist, E. F. Knipling

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

The advances during the last 15 years in our knowledge of the biology and control of arthropod pests of livestock and vectors of animal disease agents exceed those made in any similar period in past history. Before 1942 we relied mainly on rotenone, pyrethrum, the thiocyanates, and the arseni­cals for control of lice, ticks, mites, biting flies, and cattle grubs. While ef­fective against some pests under certain conditions, these materials were not practical for wide-scale use and did not meet the public demand for better insecticides. Today we have highly effective and low-cost insecticides such as DDT, lindane, TDE, toxaphene, …

The Relation Of Spring Bird Distribution To A Vegetation Mosaic In Southeastern Washington, Paul A. Johnsgard, W. H. Rickard

Paul Johnsgard Collection

Climax vegetation is of particular interest for study since it is the oldest and most stable vegetation of a region and should be expected to have a distinctive complement of animals. The purpose of this investigation was to observe the predilection of birds for stands representing climax plant associations in a remnant of native grassland in southeastern Washington.

The grasslands of this region were rapidly converted from grazing use to wheat production beginning about 65 years ago (Daubenmire 1942) and as a result only a few scattered remnants of native vegetation remain today. Associated with changes in vegetation there have …

Studies On The Trematode Larva Neascus, Thomas Reyes

University of the Pacific Theses and Dissertations

During the spring semesters of 1955 and 1956, while the writer was under the supervision of Dr. A. E. Noble, a preliminary survey was initiated on parasites in local fishes, amphibians, and reptiles occurring in the vicinity of Stockton, California. The collection of specimens in this survey included sixteen green sunfish, Lepomis cyanella, and two bluegills, L. macrochirus. Larval trematodes recovered from the heart and liver of these specimens belonged to the family Diplostomatidae Poirier (1886) which is characterized by a conspicuous constriction separating the fore and hind-bodies. The leaf-like forebody with the lateral borders converging ventrally to form a …

Effects Of Water Fluctuation And Vegetation Change On Bird Populations, Particularly Waterfowl, Paul A. Johnsgard

Paul Johnsgard Collection

In recent years reclamation activities in the Columbia Basin of Washington have resulted in profound changes in the character of the entire landscape throughout this region. The present study is an attempt to clarify some of the biological effects of impoundment behind O'Sullivan Dam in the Potholes area, Grant County (Johnsgard 1955b). In this area, a large expanse of moving sand dunes and a high water table are responsible for causing the formation of numerous small water areas, or "potholes," between the dunes. The physical nature of the area and its limited potentialities have made it of little value to …

Waterfowl Sex Ratios During Spring In Washington State And Their Interpretation, Paul A. Johnsgard, Irven O. Buss

Papers in Ornithology

Sex-ratio studies have received much attention from research workers in recent years. The contributions of Hochbaum (1944), Petrides (1944) and others have yielded considerable information on sex ratios in waterfowl; Beer (1945) and Yocom (1949) have presented data for the state of Washington. To interpret regional data on waterfowl sex ratios adequately, it is necessary to obtain a series of uninterrupted observations covering the entire migration period of the species concerned. In 1954, an ecologic study was conducted in the Potholes area, Grant County, central Washington (Johnsgard, 1956). During the period February 15 to May 16, sex-ratio data were collected …

A Taxonomic And Ecological Study Of The Ants On The Campus Of The University Of New Mexico, Tad S. Clements

Biology ETDs

This thesis attempts to indicate some of the ways in which the ants of the campus of the University of New Mexico affect man within the small area of the campus. However, my purpose of doing the study has not been strictly limited by practical considerations. Until now, no systematic study has been made of the Formicidae of the University of New Mexico Campus. Since the habitats produced artificially by man on the University of New Mexico Campus have resulted in favoring certain species of ants not found by the writer elsewhere in the region, the present study is valuable.

Fall Distribution Of Birds In A Palouse River Canyon, Frank B. Golley, Paul A. Johnsgard

Paul Johnsgard Collection

During the fall and winter of 1953 the writers undertook a general ecological study of a portion of the Palouse River valley, near Armstrong, Whitman County, Washington. During the course of these investigations records were kept on the numbers of birds observed and the vegetation in which they were located. It was anticipated that these observations might indicate bird-use of the major vegetational types found in the area. Several investigators (Dumas 1950; Wing 1949) have published distributional data for birds of the Palouse grassland during the nesting, period, but few have been concerned with distribution patterns during the fall migration.

Mammals Of The Lynndyl, Utah, Sand Dune Area : A Population Problem, Hugh J. Phillips

Theses and Dissertations

The purpose of this study was to determine the kinds, population, distribution, and general habits of the mammals of the Lynndyl sand dune area. Only one article concerning the dunes was found, but several have been written on other dunes; however, none was found concerning mammals. Two quantitative studies, plot and transect trappings, were made and general observations were taken within the study area. Three types of plots; Russian thistle, juniper, and baren moving dunes; were trapped and revealed the following species: Dipodomys ordii, Peromyscus maniculatus, Reithrodontomys megalotis, Onychomys leucogaster, and Neotoma lepida. The most numerous animal in all plots …

Natural Succession In Planted Conifer Forests In Eastern New York, Norman H. Russel

Proceedings of the Iowa Academy of Science

During the summer of 1954 the author was privileged to conduct floristic and ecological studies on the Edmund Niles Huyck Preserve, located near Rensselaerville, in Albany County, New York. This Preserve is about 470 acres in size and centers about two bodies of water. The larger is called Lake Myosotis, after the wild forget-me-not, Myosotis laxa Lehm, which is abundant along its margin. The Preserve was established in 1931, in memory of Edmund Niles Huyck, by his widow and friends, and the majority of it has been under strict and complete protection from disturbance since that time. Parts of the …
