A Taxonomic And Distributional Study Of The Crayfishes (Decapoda: Cambaridea) Of West Virginia With Diagnostic Keys To Species Of The Genera Cambarus And Orconectes, Steven M. Lawton

Theses, Dissertations and Capstones

This thesis is the first extensive investigation of West Virginia's crayfishes since Newcombe (1929) surveyed the state's fauna 50 years ago. Records, collections, and specimens were obtained from the 7 drainage areas of the state. Crayfish were collected from early spring through the fall of 1978. Both aquatic species and burrowers were included in the study. Presently, seventeen species and subspecies are known to exist in West Virginia. The genus Cambarus contains 10 of the total species of which three are primary burrowers. Cambarus nerterius, from the cavernous Greenbrier and Pocahontas counties of the Greenbrier River drainage, is the state's …

Water Usage And Power Production: The Electric Utility Industry Is Dependent On Water Utilization, T. P. Harding, L. G. Harrow

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The utilization of water as a heat transfer fluid is essential for the production of economic electrical power. There are many types of cooling facilities; however, the most economical means of electrical power production requires very large quantities of water to serve as a low temperature heat sink. For this reason, the power industry has, when possible, located its facilities near large sources of cold water, such as the Missouri River. The Omaha Public Power District (OPPD) has utilized the Missouri River since the turn of the century, and continues to do so today.

The availability of water in the …

A Taxonomic And Ecological Study Of The Cladonia Species Of The Central Portion Of Fox Ridge State Park In Coles County, Illinois, James L. Jannesse

Masters Theses

Extensive collections were made on the central ridge system at Fox Ridge State Park in Coles County, Illinois. A literature review of the works on the genus Cladonia in North America encompassed major taxonomic collections undertaken in the last 20 years. Also, a historical account on the developments in the Cladonia chlorophaea complex are listed. Basic Cladonia morphology is described, including both microscopic and macroscopic illustrations. The study area was subdivided on a grid system, enabling the collection sites to be numbered. The entire area was covered in two foot intervals. From every entity that was found, ¼ of it …

Animal-Sediment Relationship Study Of The Western Branch Of The Lynnhaven River, Charles Perry Seymour

Biological Sciences Theses & Dissertations

The animal-sediment relationships of the marine benthic infauna of an estuarine river system, Lynnhaven River, Virginia Beach, Virginia, were studied at six sites, sampled bimonthly for one year. Six species were found to dominate all of the sampling periods and sites for the year. The greatest number of individuals, biomass, and species were found at the sand sites. Deposit feeders were recorded in greater number than suspension feeders at both the sand and the mud sites.

Cluster and nodal analyses were successful in demonstrating animal-sediment relationships for the intertidal regions of the river system.

Bacteriocin-Like Substances Produced By Rhizobium Japonicum And Other Slow-Growing Rhizobia, D. C. Gross, A. K. Vidaver

Department of Plant Pathology: Faculty Publications

Bacteriocin-like substances were commonly produced by slow-growing Rhizobium japonicum and cowpea rhizobia on an L-arabinose medium. Antagonism between strains of R. japonicum was not detected in vitro; however, such strains were often sensitive to some bacteriocins produced by cowpea rhizobia. Inhibitory zones (2 to 8 mm from colony margins), produced by 58 of 66 R. japonicum test strains, were reproducibly detected with Corynebacterium nebraskense as an indicator. Quantitative production was not related to symbiotic properties of effective strains, since nine noninfective strains and one ineffective strain produced bacteriocin. Eight R. japonicum strains that did not produce bacteriocin nevertheless formed effective …

Environmental Cues In The Seasonal Development Of The Southern California Annual Grassland, George E. Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

Annual grasslands characteristically experience a succession of seasonal phases which provide for the coexistence of various species by allowing them to make their major demands upon environmental resources at different times. Thus, an ecosystem furnishing certain resources at a limited rate is enabled to support a larger total biomass.

The grasslands of southern California consist principally of annual grasses coexisting with the few remaining native perennial grasses. Characteristic also is the inclusion of forbs which are distinctly either early spring or late summer plants. Many spring forbs, annual grasses, and summer forbs are observed to germinate in approximAte unison shortly …

Distribution Of Two Species Of Long-Eared Bats Of The Genus Myotis On The Northern Great Plains, J. Knox Jones Jr., Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Two long-eared species of the cosmopolitan bat genus Myotis, the long-eared myotis (Myotis evotis) and the fringe-tailed myotis (Myotis thysanodes), have been known for many years from the Northern Great Plains. Material acquired in the last decade or so, however, reveals a somewhat different distributional pattern for the two species than had been supposed on the basis of specimens obtained earlier, some of which have been misidentified in the published literature.

The Role Of Vegetation Architecture In Determining Spider Community Organization, Cynthia L. Hatley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationships between vegetation architecture and spider community attributes were examined in a big sage (Artemisia tridentata) community. Spiders were separated into guilds using similarities of species' hunting behavior. Shrub architecture was experimentally manipulated in the field by either clipping 50% of a shrub's foliage to decrease foliage density or tying together a shrub's branches to increase foliage density.

Temporal patterns of spider species density, diversity (H') and evenness (J') showed midsummer peaks in both 1974 and 1975. Seasonal spider guild trends reflected the temporal prominence of a member species or genus. These temporally abundant species appeared to …

A Study Of Sedge-Dominated Areas In The Uinta Mountains, George Murchie Briggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-six sedge-dominated sites in the Uinta Mountains of northeastern Utah were studied. These sites could be placed into two categories, wetland sites (those with water-saturated soils) and alpine tundra sites.

The alpine sites had above-ground standing crops between 37 and 206 g/m². The soils were sandy and low in nutrients. Indirect gradient analysis of the alpine sites showed a relationship between soil stability and vegetation. No other factors were found to be related to overall vegetation patterns.

The wetland sites were dominated by different Carex species than the alpine sites. These wetlands were often patches of monotypic stands. …

Feeding Habits And Reproduction Of Three Sympatric Lizard Species From West-Central Utah, John B. Andre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The feeding habits and reproduction of Uta stansburiana, Crotaphytus collaris and Cnemidophorus tigris during spring and summer 1976 are described. Feeding habits are expressed in percent total number and volume of prey items and frequency of occurrence of each prey category. Importance Values are also calculated. These values better illustrate the feeding habits of the lizard species than either percent total number and volume and frequency of prey category occurrence.

Lizards consume a variety of food items throughout the growing season. Hymenoptera, Coleoptera, Orthoptera and Arachnida are the major prey categories of U. stansburiana. The major prey categories …

Comparison Of Microbial Activity In Desert Soils Of The Western United States, Patricia Ann Trujillo Y Fulgham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soils from four regional deserts, Great Basin, Sonoran, Chihuahuan, and Mojave, were collected at times throughout the year which would best exhibit microbial response to moisture or vegetation. The soils were analyzed for several chemical and physical properties. Biological and biochemical characteristics, namely respiration, dehydrogenase activity, adenosine triphosphate concentration, proteolytic activity, nitrification potential, and microbial numbers, were measured.

The soils exhibited fluctuations in microbial activity as measured by respiration, dehydrogenase activity, adenosine triphosphate concentration, proteolytic activity, and nitrification potential during different moisture seasons.

Increase in soil moisture as modified by precipitation did not cause a significant difference in respiration or …

Herbaceous Production In Burned-Cut Burned-Uncut And Control Areas Of A Chamaecyparis Thyoides (L.) Bsp (Cupressaceae) Stand In The Great Dismal Swamp, Caroline Elisabeth Mckinley

Biological Sciences Theses & Dissertations

The herbaceous layer of an Atlantic white cedar (Chamaecyparis thyoides) stand in the Great Dismal Swamp was sampled to estimate the productivity of two burned areas and a control area. The herbaceous vegetation was sampled along three transects utilizing the harvest method and productivity values were estimated using peak biomass values for each individual species. The burned-cut area had the highest productivity (3623 kg ha^-l yr^-1) and was characterized by species of the Asteraceae, Poaceae, and Cyperaceae. The burned-uncut area had a productivity value of 1636 kg ha^-1 yr^-1 with similar species of the Asteraceae …

Vascular Vegetation And Flora Of Remnant Forest In The Ohio River Floodplain Between The Great Kanawha And Big Sandy Rivers, West Virginia, John Carl Furry

Theses, Dissertations and Capstones

A total of 246 species of vascular plants representing 75 families were recorded from six physiographically defined forest types in the Ohio River floodplain between the Greet Kanawha end Big Sandy Rivers, West Virginia. Distinct woodlands were those associated with the River flats, River front, bottoms of secondary streams, stream banks, the high floodplain end swamps. Only two species, Acer saccharinum and Platenus occidentalis representing 0.81 percent of the total species encountered, were present in all forest types; 105 species (42.7 percent) were restricted to one forest type. Fifty-five species were new additions to the flora of one or more …

Food Of The Red Drum, Sciaenops Ocellata, From Mississippi Sound, Robin M. Overstreet, Richard W. Heard

Gulf and Caribbean Research

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species …
