An Ecological Study Of An Exclosure In The Mountain Brush Vegetation Of The Wasatch Mountains, Utah, Elray S. Nixon

Theses and Dissertations

This is a comparative study of the vegetation and soils of an exclosure in the mountain brush vegetation of the Wasatch Mountains, Utah. The exclosure was fenced and initially analyzed during the summers of 1949-1950. The study area is located in Pole Canyon in the Uinta National Forest, a few miles northeast of Provo, Utah. The dominant woody species of the vegetation in the exclosure are big toothed maple (Acer grandidentatum) and Gambel oak (Quercus gambelii). After settlement of the area in and around Provo, Pole Canyon became overgrazed by livestock. Since 1949 the area has been protected from grazing. …

Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton

Masters Theses

Chapter I

Introduction

In discussing the basis for teaching high school biology, Van Deventer¹ states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …

Mammals Of Mount Taylor, Valencia County, New Mexico, Eugene E. Schroeder

Biology ETDs

During the summer of 1960, three months were spent in making a comprehensive study of the kinds and ecological distribution of native mammals in and above the Transition Zone on Mount Taylor of Valencia County, New Mexico.

Mount Taylor, and old volcanic pile, rises 11,301 feet above sea level. Three boreal life zones, the Transition, Canadian, and Hudsonian were assigned to Mount Taylor.

Small mammals were collected by two sampling methods, quadrant and line trapping. However, mist nets were used for capturing bats. Quadrants were placed in various plant communities for three successive nights. Numbers and kinds of mammals recorded …

The House Fly (Musca Domestica), Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

MANY insects are so commonly associated with man and his dwellings that they may almost be called domesticated.

In olden days the presence of these insects was accepted as a matter of course, but present knowledge shows that many of them can be important disease carriers while others may cause damage to food and clothing.

Dwarf Fruit Trees, Frank Melville

Journal of the Department of Agriculture, Western Australia, Series 4

IN this country where most fruits and particularly apples and pears are grown without irrigation, heavy crops and summer stress restrict tree size.

The aim of most growers therefore, has been to grow larger trees and little interest has been shown in trees with dwarfing tendencies.

However, in countries with ideal conditions for growth, trees tend to grow too big and become uneconomic in terms of labour costs.

Control Of The Emu, C D. Gooding, J. L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

Vermin research officers C. D. GOODING and J. L LONG give the latest recommendations for control of the emu, based on a series of observations and poisoning experiments in the northern wheatbelt.

Humidity Graph Of Saddleback Biotic Succession, Jane Claire Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

This document reflects the succession of growth in the Saddleback research station. The old forest, it shows, was eventually replaced by stages of regrowth after logging, but never fully recovered.

Ecosystem Studies At Cedar Creek Natural History Area, Iii: Water Use Studies, A. N. Bonde, J. D. Ives, D. B. Lawrence

Journal of the Minnesota Academy of Science

Previous articles in this series (Lawrence et al. 1957-58, 1960) have dealt with the nature of ecosystems, history of the ecosystem analysis approach, and some of the objectives and the methods that have been used at the Cedar Creek Natural History Area of the University of Minnesota and the Minnesota Academy of Science. The area, which was acquired in large part through a generous grant from the Fleischmann Foundation, is located in Anoka and Isanti Counties in east central Minnesota. The work has been generously supported by the Hill Family Foundation since the early summer of 1957.

One main objective …

Influence Of Logging On Douglas Fir Beetle Populations, R R. Lejeune, L H. Mcmullen, M D. Atkins

The Bark Beetles, Fuels, and Fire Bibliography

All species of bark beetles of economic importance prefer to attack freshly-killed host material. Logging slash, wind-throw, and fire-killed timber provide ideal breeding grounds for bark beetles. A few species, mostly in the Dendroctonus group, are able to kill living trees. When beetles in the group, raised in preferred host material, cannot find any or enough freshly-killed trees, logs, or slash to enter, they may attack living trees. In the interior of British Columbia, infestations of the Douglas fir beetle can often be traced to logging disturbance.

Bee Farming : Maintaining Productive Stock, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 4

EVERY bee hive must be a productive unit, headed by a young vigorous queen, to to make sure of the greatest possible return from capital invested in the commercial apiary.

Vermin Symposium Report : Wanted : A New Approach To Rabbit Control, A R. Tomlinson

Journal of the Department of Agriculture, Western Australia, Series 4

THE main reason why rabbits have not increased as rapidly as their amazing capabilities might have led people to expect has been a series of years not suitable for full breeding.

This has been more important than myxomatosis and "1080". This was one of the thoughts taken away by those who attended the rabbit control symposium held in Perth recently.

Letter From Lawrence W. Quate To Dr. Jane C. Dirks-Edmunds, Lawrence W. Quate

Jane Claire Dirks-Edmunds Documents

This letter from Dr. Lawrence W. Quate is one of many such letters received by Dr. Jane Claire Dirks-Edmunds. Dirks-Edmunds consulted a number of experts to help identify the specimens she collected while conducting fieldwork. Quate was an expert on midges, also known as psychodids. Many of the colleagues with whom Dirks-Edmunds corresponded resided far afield from her research site on Saddleback Mountain in Oregon.

Dirks-Edmunds, a 1937 graduate of Linfield College, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

Studies In Experimental Evolution, William Sidney Boyle

Faculty Honor Lectures

The Principle of organic evolution is the most fundamental one yet discovered in the sciences concerned with the nature and origin of living things. During the one hundred years which have elapsed since Darwin's explanation of the mechanisms of evolution a great deal has been learned to supplement his theory. Nevertheless, students of evolution universally acknowledge the significance of his profound contributions. The importance of natural selection as a creative force in evolution is inescapable.

The present discussion is chiefly concerned with techniques which the writer has used to accelerate, or at least to manipulate, the evolutionary processes. It may …

Preliminary Report: Monolayer Behavior Studies, 1959, Bureau Of Reclamation

Publications (WR)

During the fall of 1959, monolayer behavior studies were made on two lakes in the southwest; Boulder Basin of Lake Mead, Nevada, and Lake Sahuaro near Phoenix, Arizona. These studies were made to evaluate the effect of geographical and climatological conditions on movement and behavior of monolayers. The Lake Sahuaro tests also were used to provide data for design and development of improved methods of application and maintenance of a film on this lake in anticipation of full scale, evaporation-reduction tests to be performed there during the summer of I960. The Lake Mead studies produced the following general points of …

Wild Dog Control In The North-West, R J. Fraser

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of its sparsely-settled condition, the North-West of Western Australia is almost an ideal breeding-ground and hunting-ground for wild dogs.

Even the best of the pastoral country is but thinly populated and there are large areas of rugged country which is seldom traversed by white men.

Rabbit Control In 1960, C Marshall

Journal of the Department of Agriculture, Western Australia, Series 4

IN the year 1859, an enthusiastic sportsman in Victoria took delivery from the clipper "Lightning" of a small consignment of wild European rabbits which he joyfully released on his estate at Barwon Park, near Geelong, in order to assure himself of some rough shooting.

He was not the only rabbit importer on record—tame rabbits were brought into Australia before and after 1895 and doubtless there were other importations of the wild rabbit—but he is generally credited—or discredited—with having triggered off the rabbit plague.

A Successful Campaign Against The Euro, E H M Ealey, T. M. Richardson

Journal of the Department of Agriculture, Western Australia, Series 4

RESULTS from a five-year research programme carried out by the C.S.I.R.O. on the Abydos-Woodstock Pastoral Research Station indicated that euros could be controlled in a practical and economic way by the traditional method of water poisoning,

if it was continued for an extended period and carried out over a large area. Smallscale trials supported this claim, but no opportunity had occurred to assess the practicability of a large-scale poisoning operation.

Termites Or White Ants, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.

Grasshoppers And Locusts In Western Australia, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

GRASSHOPPERS and locusts are among the most ancient enemies of the farmer, for they figured prominently in Biblical times, and periodically throughout the ages have devastated crops in all parts of the world.

The Romney Marsh, J A. Mallett

Journal of the Department of Agriculture, Western Australia, Series 4

THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.

Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.

In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …

Notes On Scottsbluff, Nebraska, Tornadoes, 27 June 1955, Robert G. Beebe

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Some general characteristics of thirteen tornadoes that occurred on the afternoon of June 27, 1955 in Scottsbluff County, Nebraska, are related. Two of these caused widespread attention due to their size and their proximity to the cities of Scottsbluff and Mitchell, Nebraska. These two were photographed extensively by residents near their paths. The experience of two men directly beneath one of the two large tornadoes is related.
