Thermal Ecology And Movement In The Leopard Lizard, Gambelia Wislizeni, Baird And Girard, Marvin Lynn Abts

Dissertations and Theses

Thermal ecology and movement of the Leopard Lizard, G. wistizeniwere studied at Frog Spring, adjacent to the Alvord Desert, and at various locations throughout the Alvord Basin. Seasonal activity is known to occur from early May to mid-October, but abundance. gradually decreases after late July. During favorable late spring, and summer weather lizards exhibit a bimodal pattern of diel activity with some activity occurring at all hours of the day between 0600 and 1800 H. At other times activity was unimodal. Emergence was apparently largely temperature dependent and did not occur until sand temperature approximated 21°C. Retreat appeared to …

Species Diversity And Distribution Of Fish In Lake Nicaragua, Kurt W. Koenig, Richard J. Beatty, Sergio Martinez C.

Investigations of the Ichthyofauna of Nicaraguan Lakes

The results of a preliminary study of the abundance, diversity and distribution of some of the fish species in Lake Nicaragua are presented here. These parameters have received little attention from investigators working on the lake.
A frequently used measure of species diversity is the Shannon-Weiner diversity index. It measures the degree of uncertainty of predicting the species identity of a randomly selected individual (Pielou, 1966). Lloyd and Ghelardi (1964) indicated that species diversity indices are influenced by both the species number, or "richness", and the species "evenness", or relative number of individuals of a species in a given habitat. …

The Behavior And Ecology Of Herotilapia Multispinosa (Teleostei, Cichlidae), Jeffrey R. Baylis

Investigations of the Ichthyofauna of Nicaraguan Lakes

Because of their complex social behavior and the ease with which they can be manipulated, cichlid fishes have long been of special interest to the ethologist. However, most of the research into cichlid behavior has been on Old World species. The social behavior of New World species is different and deserves more study. This paper will describe the ethology of one of the Central American cichlids, Herotilapia multispinosa.

Prospects For Control Of Phytopathogenic Bacteria By Bacteriophages And Bacteriocins, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

The last review on bacteriophages and bacteriocins of phytopathogenic bacteria was that of Okabe & Goto (98). All but one (21) of the subsequent reviews (II, 12, 60, 94, 104) have dealt primarily with viruses and bacteriocins of bacteria other than phytopathogens. The most recent microbiological compendia that in­ clude bacteriophages and bacteriocins are of limited value for phytobacteriolo­ gists because the authors generally overlook or ignore such agents (29, 47, 77, 119). However, Adam's classic .book (4), the review by Bradley (II), and the bibliography of Raettig (102) are still of value to phytobacteriologists as are reviews dealing principally …

Timpanogos Flora, Kelly W. Allred

Theses and Dissertations

A comprehensive floristic study of Mt. Timpanogos, Utah County, Utah, was undertaken. The Mt. Timpanogos area is a much used facility in recreation, biology, watershed development, livestock management, and education. It is also representative of a major segment of the overall flora of Utah. This study adds to the ever-increading knowledge of the flora of Utah, and provides a means of identifying the flora of this region, which is basic to any future management.

Interactions In The Frequencies Of Electric Organ Discharge By Eigenmannia Virescens (Sternopygidae, Pisces) During Social Behavior, Philip Gaddis

Dissertations and Theses

The extent to which individuals of Eigenmannia virescens modulate their electric organ discharge frequencies to accommodate the frequencies of others of the same species during social interactions was investigated. Recordings of the fish's discharge frequencies, taken with Tektronix 3L5 and 5L4N spectrum analyzers, showed that, although movements of up to 60 Hz in a day may be made, the frequency movements would be made more or less synchronously by all fish in the group. An apparent preference for, and a tendency of the fish to follow one another in frequency, at frequency ratios of 2:3 (a musical fifth), 3:4 (fourth), …

Integration Of Forage Production And Range Improvement In The Irrigated Gezira Scheme In The Sudan, Abdel Gader Ahmed Osman

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Gezira is an area of land, a part of the Democratic Republic of the Sudan, which lies between the Blue Nile and the White Nile. The area extends in a triangular shape from the junction of the two Niles at Khartoum on the north to the city of Sennar on the south (Figure 1). The area of this extremely flat plain is approximately two million hectares, one million of which are irrigable. It is considered the largest farm under one management in the world (Barbour, 1961).

Diatom Phytoplankton And Periphyton Studies Of The Headwaters Of Henrys Fork Of The Snake River, Island Park, Idaho, Richard L. Clark

Theses and Dissertations

An ecological baseline study of the diatom flora was conducted on the headwaters of Henrys Fork of the Snake River, Idaho. The diatom flora of this spring fed drainage basin consisted of both phytoplankton and periphyton. Thirty-nine genera, two hundred forty-four species, eighty-two additional varieties, and seven additional forms were identified from these waters. Species of Melosira, Stephanodiscus, Fragilaria, Synedra, and Asterionella were found in the plankton of Henrys Lake and Island Park Reservoir. Diatoma, Fragilaria, Synedra, Eunotia, Achnanthes, Navicula, Pinnularia, Gomphonema, Cymbella, Nitzschia, and Surirella were the important genera present in the periphyton.

Comparison Of Artificial Substrates In Bottom Fauna Studies On A Large River, David R. Mcconville

Journal of the Minnesota Academy of Science

During the summer of 1974, five types of artificial substrates and grab sampling were evaluated for sampling efficiency in pool No. 3 of the Upper Mississippi River. A total of 35 taxa of organisms were collected by the different techniques. Ponar grab sampling collected representatives of only eight taxa, whereas concrete block samplers collected 22 taxa . Intermediate in taxonomic collection were the Hester-Dendy samplers with 21 taxa, the barbecue basket samplers with 20 taxa, the Miller samplers with 17 taxa, and conservation webbing with 12 taxa. The barbecue basket samplers were the most productive, yielding at least five times …

Studies On Schistosome Dermatitis ('Swimmer's Itch") In Minnesota, Donald E. Gilbertson, Richard Wedlund

Journal of the Minnesota Academy of Science

A preliminary study was conducted to determine the causative agents of schistosome dermatitis ( "swimmer's itch") in Minnesota and to determine the incidence schistosome infection in vector snails. A total of 1180 snails were collected from ten different localities, eight of which were sites of known schistosome activity . The incidence of schistosome infection in snails from individual areas was always less than 10 percent. Cercariae of Trichobilharzia ocellata from Lymnaea stagnalis were the most frequently-found schistosomes in our study.

Food And Distribution Of Underyearling Brook And Rainbow Trout In Castle Lake, California, Wayne A. Wurtsbaugh, R. Brocksen, C. Goldman

Watershed Sciences Faculty Publications

A difference was found in the summer distribution of underyearling brook trout, Salvelinus fontinalis (Mitchill), and planted rainbow trout, Salmo gairdneri Richardson, in Castle Lake, California. Brook trout underyearlings oriented to the bottom and were found primarily in shallow water on the eastern shore of the lake near springs. The rainbow trout underyearlings were more pelagic and were found in the littoral areas along the entire shoreline. Gravimetrically, the food eaten during the summer by brook trout underyearlings was 13% terrestrial, 11% limnetic, and 76% benthic. Rainbow trout ate 15% terrestrial, 15% limnetic, and 70% benthic food. In summer, rainbow …
