Movement Of Franklin's Ground Squirrel Into Northeastern Minnesota, Jerome D. Robins

Journal of the Minnesota Academy of Science

Specimens of Franklin's ground squirrel have been obtained in several localities in St. Louis County, Minnesota. The movement of this prairie-dwelling rodent into the montane coniferous forest region of northeastern Minnesota may be related to recent man-made changes in the habitat.

Reproduction And Growth Of The Tule Perch Hysterocarpus Traskii (Gibbons) With Notes On Its Ecology, David Scott Bundy

University of the Pacific Theses and Dissertations

This study was initiated to obtain information about the natural history of the tule perch before greater reduction in population has occurred. The studies of Hopkirk (1962) and Turner (1966) did not include information on reproduction, development, and growth of embryos within the ovarian sac, and the growth of the tule perch and, secondly, to supplement the work of Hopkirk and Turner concerning color variation and food habits.

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

Incidence Of Trematode Infection Of Snails In A Small Minnesota Lake, Ellen Shaffer

Journal of the Minnesota Academy of Science

The study on which this paper is based was a preliminary effort to determine three factors: (1) the nature of the snail and trematode fauna of a small lake, (2) the incidence of trematode infection in the snail population, and (3) possible changes in the incidence of trematode infection in snails at various periods in a single summer.

Progress In Research On Noxious Weeds, Geoffrey A. Pearce

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

RESEARCH on noxious weeds has enabled the development of many practical methods for the control of these weeds.

Where the recommended treatments have been accepted by farmers, large scale operations have reduced the areas infested and stopped spread into new paddocks.

Seasonal Abundance And Distribution Of Benthic Fauna Within A Pond, Ellis L. Matheny, E. A. Heinrichs

Department of Entomology: Faculty Publications

A Tennessee pond was sampled weekly from June 18 to August 20, 1968, to determine quantitative differences among benthic organisms in sampling depths and dates. Annelids (Oligochaeta), Chironomidae larvae, and Chaoboridae larvae were the dominant organisms collected. Preferred depths existed for each group of organisms. Chaoboridae and Chironomidae exhibited distinct seasonal variations in numbers, with the population decreasing throughout the summer. Chaoboridae were the most and Chironomidae the least numerous of the 3 groups.

A Taxonomic And Ecological Study Of The Desmids Of Lily Lake, James L. Pederson

Theses and Dissertations

During the summero f 1964 a taxonomica and ecological study was made of the desmids (microscopic green algae) found in Lily Lake. The study site is a subalpine lake in the Wasatch National Forest of the Uinta Mountains, Utah. The lake is located about one-half mile west of Trial Lake at an elevation of approximately 10,000 feet. The lake is an acidic, cold, lentic bog pond characteristic of this region. Desmids were collected at weekly intervals from seven sampling sites. The water temperature, pH, dissolved oxygen, light conditions and length of day from sunrise to sunset were recorded at the …

A Study Of Conifer Invasion Into Meadows Surrounding Small Lakes And Ponds In The Trial Lake Region Of The Western Uinta Mountains, David Harvey Firmage

Theses and Dissertations

The object of this study was to determine whether or not Lodgepole pine is successfully invading meadows near ponds in the western Uinta Mountains as a preliminary step to the invasion of the Spruce-Fir climax forest. Line transects were established at three sites near Trial Lake extending from forest to wet meadow. Along these transects the soil was studied to determine percent organic matter, pH, depth to mineral soil, and texture. Also the depth of the water table was measured and the topography plotted. The age and size of the trees along the transect was determined, and the extent of …

Ecology Of The Pika (Ochotona Princeps Uinta) In The Uinta Mountains, Utah, Richard D. Bates

Theses and Dissertations

In North America, pikas (mammal genus Ochotona) are distributed throughout the western mountain ranges where they are mostly restricted to higher elevation talus slides. There are two species in North America, the Alaskan or Collared Pika (Ochotona collaris Nelson) and the American Pika (Ochotona princeps Richardson). The former is found north of 58 degrees north latitude and has no subspeciation, while the latter occurs south of 58 degrees latitude and consists of 35 subspecies isolated on various mountain ranges (Hall and Kelson 1959). In Utah there are nine subspecies, which are mostly distributed in the Wasatch range that runs northeast …

A Study Of Aquatic Fungi In Powell's Slough, Chao-Chih Hsiao

Theses and Dissertations

Aquatic fungi in-Powell's Slough were.studied in 1967 & 1968. Collections were made and water temperature, oxygen content & pH values were measured at weekly intervals. For collections, wire baskets containing substrata were submerged in water for one month. After collecting, substrata were brought to the laboratory. Identification was based on the keys of Sparrow, 1960. Aquatic fungi identified included seven orders, nine families, fifteen genera, and thirty species, from thirty-three collections of fifteen types of substrata. The substrata used in this study were: (i) fruits: apples, rose hips, plums, pears, haws; (ii) twigs: poplar, weeping willow, river birch, weeping white …

Factors Affecting Mourning Dove Use Of Water In Artificial Catchment Basins In A Dryland Farming Area Of Utah, Norman A. Slade

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mourning dove population of the Howell-Blue Creek Watershed in northern Utah was studied by Norman Slade in an effort to determine why many more doves frequented certain of the 20 fiberglass catchment basins installed in the area.

More doves used basins on the west side of the valley, probably as a result of temperature differences. More doves used those basins surrounded by more land in summer fallow and with fewer basins nearby. Areas in sagebrush were used for nesting.

The number of doves drinking in a particular hour was affected by the presence of predators or antagonists but not …

Overwintering Of Erwinia Amylovora Inside Living Host Tissue In Cache Valley, Utah, G. Doyle Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments were conducted to see if Erwinia amylovora (Burrill) Winslow et al. overwinters inside living host tissue in Utah. Bacteria, collected from apple, pear, mountain ash, chokecherry and Pyracantha, were used in the experiment. Isolates taken from buds and inner bark plated on nutrient yeast dextrose agar, we re tested by serological and bacteriophage techniques. Those showing positive tests were then inoculated into Bartlett pear seedlings to test virulence.

Both virulent and avirulent isolates were isolated from each species of plant in the experiment. Pathogenic bacteria were isolated from diseased tissue near cankers, as well as from apparently healthy inner …

Light Interception And Radiative Exchange In Crop Stands, John Monteith

Department of Agronomy and Horticulture: Faculty Publications

Crops grow and use water because they intercept radiation from the sun, the .sky, and the atmosphere. Diurnal changes of solar radiation dictate the diurnal course of photosynthesis and transpiration, and the vertical gradient of radiant flux in a canopy is a measure of the absorption of energy by foliage at different heights. Without exaggeration, the distribution of radiation within a plant community is the most important single element of microclimate.
Early ecological studies of radiation climate were mainly descriptive and were limited in scope by rather primitive instrumentation. A new quantitative approach to the subject was initiated by Monsi …

Mourning Dove Status Report, 1967, James L. Ruos, Duncan Mcdonald

United States Fish and Wildlife Service: Publications

Nationwide dove population indexes in the 1967 Mourning Dove Status Report were obtained by essentially the same data gathering and analyzing procedures as in 1966. A refinement was made in the base year index, using the mean of the 1966 and 1967 readings as the base for all States. There was a slight adjustment in physiographic region boundaries.

Thrips Of The Sagebrush-Grass Range Community In West-Central Utah, Ward Max Tingey

Theses and Dissertations

Three predominant and economically important shrubs of the sagebrush-grass range community in Utah, namely big sagebrush (Artemisia tridentata Nutt.), rubber rabbitbrush (Chrysothamnus nauseosus (Pall.) Britt.), antelope bitterbrush (Purshia tridentata (Pursh) DC), and a widely re-seeded range grass, crested wheatgrass (Agropyron cristatum (L.) Gaertn.) were sampled during the summers of 1966 and 1967, and yielded twenty species of thrips. Three species (Anaphothrips tricolor Moulton, Chirothrips aculeatus Bagnall, Chirothrips simplex Hood) were new distributional records for Utah. Seven species (Frankliniella n. sp. #1, Frankliniella n. sp. #2, Haplothrips n. sp., Leptothrips n. sp., Oedaleothrips n. sp., Sericothrips n. sp. #1, Sericothrips n. …

Overwintering Sites And Winter Mortality Rates Of Certain Predaceous Mites In Central Utah Orchards (Phytoseiidae: Typhlodromus), John Wayne Leetham

Theses and Dissertations

The overwintering habitats and winter mortality rates of predaceous mites (Phytoseiidae: Typhlodromus) were investigated during three successive winters, 1965-66, 1966-67, and 1967-68. Three species were predominant in derelict apple orchards, Typhlodromus mcgregori Chant on twigs and spurs and rough bark of scaffold limbs and trunk, Typhlodromus occidentalis Nesbitt on rough bark of scaffold limbs and trunk, and Amblyseius cucumeris Oudemans in ground cover. Other species (Typhlodromus columbiensis Chant, Typhlodromus caudiglans Schuster, Amblyseius fallacis (Garman), Amblyseius ovatus (Garman), Amblyseius floridanus (Muma), and Amblyseius rosellus Chant) were collected only incidentally. Substantial numbers of T. mcgregori and T. occidentalis were found to fall …
