The investigation was designed to uncover such information about the alpine flora and environment necessary to establish the pattern of succession .

An Ecological Study Of The Utah Sculpin Cottus Bairdi Semiscaber In Logan River, Utah, William Merle Zarbock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of the Utah sculpin Cottus bairdi semiscaber, or Rocky Mountain bullhead as it is known locally on Logan River, Utah, is primarily one of determining its relation to game fish. Field work for this study began in 1949 and continued to March of 1951. Numbers of the Utah sculpin on Logan River have been estimated to be as high as 150 per tenth mile of stream. The larger populations are in the area of the third impoundment on Logan River and downstream.

Ecological Studies In A Midwestern Range: The Vegetation And Effects Of Cattle On Its Composition And Distribution, J. E. Weaver, G. W. Tomanek

Department of Agronomy and Horticulture: Faculty Publications

There is continued need for a better understanding of range vegetation and its use by range animals. Range preservation and improvement in the midwest are largely matters of wise use and proper management of our natural grasslands. A more comprehensive understanding of the range itself is needed--its forage, soil, and water supply, and factors influencing a proper distribution of livestock. The degree of utilization of forage that will result in the maintenance of excellent or good range condition and the improvement of a range in fair condition should be ascertained. Soil conservation on range lands is accomplished primarily by improvement …

Enemies Of Aspen, Clyde M. Christensen, Ralph L. Anderson, A. C. Hodson, Paul O. Rudolf

Aspen Bibliography

So long as aspen was considered primarily a weed species, there was little concern over the enemies which might injure or destroy it. Sometimes these enemies were actually considered "blessings in disguise. Now, however, that aspen not only is the most abundant "but also one of the most widely utilized tree species in the Lake States, there is increasing interest in anything that may affect its future supply. For that reason this brief summary of information on the enemies of aspen has been assembled.

Preliminary Report On The Distribution Of Bottom Organisms In West Lake Okoboji, Iowa, John E. Bardach, John Morrill, Frank Gambony

Proceedings of the Iowa Academy of Science

"Little is known of the bottom fauna of the locality." This passage is taken from an Extension Bulletin of the State University of Iowa which describes the Iowa Lakeside Laboratory on West Lake Okoboji and its facilities for biological investigations. It should be stressed at the outse.t that there are few lakes which do not share with Okoboji this relatively unexplored state of their bottom biota. A study was begun in July 1950 with a view to eventually answering the following questions: 1. What is the distribution of macroscopic bottom dwelling animals in the lake? 2. Does this distribution follow …

Relation Of Fishes And Other Organisms To The Scattering Of Underwater Sound, Gordon H. Tucker

Journal of Marine Research

An analysis of concurrent sound-scattering records and biological collections in the sea show a correlation of the deeper and more intense scattering of sound with fishes and of the upper and lighter scattering with a dominant population of euphausiids. The main group of fishes concerned are the Myctophidae, which possess all of the essential qualifications of scatterers.

Biotic Interrelationships Of Helminth Parasitism, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Biotic interrelationships in Alaska have so far suffered little from man's attempts to improve upon nature. As a result of these favorable circumstances, biological investigation in Alaska offers unusual opportunity for elucidating problems which can no longer be approached in the more populated parts of North America. One is very fortunate to have the opportunity of working under these conditions, since present trends indicate that Alaska is soon to go by the way of the great wildernesses which once existed in the United States and Canada.

An Ecological Study Of The Relationship Between Direction Of Slope, Elevation, And Forest Cover In Brown County, Indiana, Carl R. Mcqueeney

Butler University Botanical Studies

The complexities of our deciduous forests, though constantly under the scrutiny of investigators from various fields of botany, present many problems which are poorly understood. Each area, regardless of size, presents new problems which may or may not be peculiar to the area in question. For this reason, it is imperative that as problems arise, they be treated in a quantitative, comparative manner. The primary object of this study is to illustrate the limits placed upon various species of tall trees by environmental factors introduced as a result of the direction and angle of the exposure, as well as the …

The Ecological Distribution Of Mammals Of Green Canyon, North Logan, Cache County, Utah, And Their Relation To Plant Communities, Charles J. Stewart

Biology

The interrelationships that exist between mammals and their habitat have been of profound interest to mammalogists and ecologists for many years. The ecology of the mammal has been given equal rank with that of its taxonomy and distribution. It becomes apparent to anyone studying mammals that a great affinity exists between them and the habitat in which they live.

Monolith Method Of Root-Sampling In Studies On Succession And Degeneration, J. E. Weaver, John Voigt

Department of Agronomy and Horticulture: Faculty Publications

A new method has been devised by which a complete sample of an entire root system may be taken from soil surface to maximum depth of penetration. The roots are separated from the soil without injury to them or displacement of individual roots from their natural position. They are examined in the laboratory in relation to the various horizons of the soil profile. Monoliths 12 inches wide, 3 inches thick, and 3-5 feet in depth are taken from the walls of trenches made in selected pure stands of each species. Roots are obtained from the monolith by a system of …

An Ecological Study Of The Foraminifera Of Mason Inlet, North Carolina, Daniel N. Miller Jr.

Masters Theses

"Mason Inlet. North Carolina is a lagoonal marsh area with warm-temperate water, the salinity ranging from fresh to salt water. Nine collecting stations comprise an ecological gradient across the environment.

Forty-two species of foraminifera are recorded from the inlet, ranging in their affinities from brackish water to open-sea facies. Several extensions of range are recorded both northward and southward.

Substratum conditions apparently control the distribution of foraminifera within the inlet. Clean, fine sand provided the largest faunal populations. A depauperate assemblage was found in an inorganic, argillaceous substratum. The largest population of arenaceous forms was found at the channel through …

An Ecological Study Of Helminths Of Some Wyoming Voles (Microtus Spp.) With A Description Of A New Species Of Nematospiroides (Heligmosomidae: Nematoda), Merle L. Kuns, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

An ecological and taxonomic study of the helminth parasites of voles (Microtus spp.) in the Jackson Hole region of Wyoming is reported.

Nematospiroides microti n. sp. from Microtus montanus nanus and M. richardsoni macropus is described and figured.

A cestode, Paranoplocephala infrequens, and a nematode, Syphacia obvelata, were generally distributed throughout the region in all habitats except the sage flats.

A trematode, Quinqueserialis hassalli, was recovered only from voles collected near streams at low altitudes. This was presumably due to the localized distribution of the molluscan intermediate host.

Four helminths, viz., Hymenolepis horrida, Heligmosomum costellatum …

Studies On The Ecological Distribution Of The Genus Tegula At Bodega Bay, California, Allen Emmert Breed

University of the Pacific Theses and Dissertations

This paper is primarily a study of the factors contributing to the distribution of Tegula funebralis and Tegula brunnea in the vicinity of Bodega Bay, California. The two species seldom appear extensively together in the same zone. Tegula brunnea is found on the exposed outer coast of Tomales Point, but not in the immediate zone of Tegula funebralis. Tegula funebralis is found at some points north of Dillon Beach, but it is rarely in the presence of abundant Tegula brunnea. The writer hopes that his efforts may lay a basis for more ecological studies of this genera on the Pacific …

A Comparative Ecological Study Of Two Forest Stands In The Illinoian Drift Plain Area Of Southern Indiana, Jack B. Secor

Butler University Botanical Studies

The rather uniform till plain topography of Indiana would seem, naturally, to imply a homogeneity and uniformity in the plant cover; such, however, is not the case. Friesner has indicated that the state is in a critical location in reference to the distribution and geographical limitations of numerous and varied plant species.

These vegetational differences are especially marked when forest types within the deciduous forests are involved. Potzger has found that microclimatic features are of sufficient importance to vary expression in oak-hickory or beech-maple type by the mere difference of south- or north-facing ridge exposures.

An Ecological Survey Of The Crawford Woods, Clark County, Indiana, Jack B. Secor

Butler University Botanical Studies

Numerous surveys of forested areas throughout Indiana have yielded a wealth of ecological knowledge, especially in regard to factors controlling and regulating the invasion and ecesis of deciduous tree species making up these forest formations. Perhaps no other area in the state has undergone a more intense study by ecologists than the Illinoian Drift Plain region, located in the southern part.
