Influence Of A Dry Wash Habitat On Distribution And Movement Of Heteromyid Rodents, Jeffrey S. Green

Theses and Dissertations

Three heteromyid rodent species were studied in relation to a large dry wash in Millard County, Utah, during the summer, 1974. Data were gathered with three trapping grids and analyzed to determine if the dry wash influenced rodent movement and distribution patterns. Dipodomys ordii and Dipodomys microps were distributed non-randomly in the dry wash and adjacent habitat, but Perognathus Zongimembris seemed to be randomly distributed. Dipodomys ordii was significantly correlated with wash habitat, but D. microps was found most frequently in upland areas. Soil and vegetative differences and competition were possible causes for the observed distribution. The wash was observed …

Macrobenthos Population Changes In Crystal Lake, Arkansas, Subsequent To Cage Culture Fish, James C. Adams, Raj V. Kilambi, William A. Wickizer, Arthur V. Brown

Journal of the Arkansas Academy of Science

A three-year study was conducted to determine the possible effects of cage culture of fish on the environment of Crystal Lake, Arkansas. The investigation consisted of three periods: pre- (November 1971-October 1972), during- (November 1972-October 1973), and post- (November 1973-October 1974) cage culture. Numbers and biomass of benthos per square meter for pre-, during-, and post-culture periods were 1353 (10.0g), 730 (8.8g), and 1028 (4.1g), respectively. Numerically, Chaoborus sp., Chironomidae, and Oligochaeta comprised more than 97%. Chaoborus was the most numerous organism before fish culture (>68%), but dominance shifted to the Oligochaeta (>58%) after culture.

Distributional Records Of Amphibians And Reptiles From Coastal Plain Of Arkansas, Edmond J. Bacon Jr., Zane M. Anderson

Journal of the Arkansas Academy of Science

Distribution of amphibians and reptiles in the West Gulf Coastal Plain and Mississippi Alluvial Plain is not well known because extensive collecting has not been done in these areas and data in museums have not been published. New distributional records for three salamanders (Desmognathus fuscus brimleyorum, Manculus quadridigitarus, Plethodon glutinosus glutinosus) , two anurans (Rana areolata circulosa, Scaphiopus holbrooki holbrooki), and one snake (Lampropeltis doliata amaura) are presented. Additional collecting will be necessary to determine the exact range and status of the secretive species.

Effect Of Salinity On Glycogen Content In The Brine Shrimp, Artemia Salinas, Of Great Salt Lake, Christon H. Merkley

Undergraduate Honors Capstone Projects

The brine shrimp, Artemia salinas, is one of the few organisms to be found in the hostile environment of the Great Salt Lake. Salt concentrations in the lake are found to exceed those in the oceans. In such an environment, the utilization of energy, even after it has been procured, presents a problem. The life inhabiting the lake has developed extraordinary adaptations to this and similar problems.

Electron micrographs produced by Dr. Nabil Youssef of Utah State University have revealed that unusual quantities of glycogen can be found in the muscle of brine shrimp taken from the Great Salt Lake. …

A New Subspecies Of Geomys Bursarius (Mammalia: Geomyidae) From Texas And New Mexico, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

As part of a study of the systematics and ecology of pocket gophers occurring on the high plains of Texas and eastern New Mexico, numerous populations of the plains pocket gopher, Geomys bursarius, were examined karyotypically. Four chromosomal races were described from this area by Baker et al. (1973). Additional studies lead us to believe that two of these races represent an undescribed subspecies of the plains pocket gopher. In addition to karyological evidence, specimens of this subspecies are morphologically distinct from those of all contiguous populations of Geomys bursarius major, the race to which they previously were assigned. …

A Comparative Study Of Some Population Characteristics Of Calyptraea Fastigiata Gould, Crepidula Lingulata Gould, And Crepidula Nummaria Gould (Gastropoda, Prosobranchia), Roger Harold Goodwill

Theses and Dissertations

A comparative study of the field populations of Crepidula lingulata, Crepidula nurnmaria, and Calyptraea fastigiata indicated all three preferred a rocky substrate but favored different size rocks. Their positions on the rocks varied but the greatest numbers were found attached to the undersides. Crepidula lingulata and C. nummaria preferred larger rocks and were found in intraspecific associations more often than C. fastigiata which preferred smaller rocks. These associations occurred with a 1:1 sex ratio; however, the overall population did not. Crepidula lingulata had a high female count and C. fastigiata a high male count. Males, of all three species, were …

Oregon's Nutria Problem, Lee W. Kuhn, E. Paul Peloquin

Vertebrate Pest Conference Proceedings: 6th (1974)

The nutria or coypu, Myocastor coypus, is a large semi-aquatic rodent that superficially resembles an overgrown muskrat or a stunted beaver. They were introduced into Oregon from about 1930 to the 1950s. At one time Oregon had more than 600 fur farmers raising these animals for fur; now there are none. Some animals escaped and many others were released into the wild when it became apparent that pelt values were nonexistent and production costs greatly exceeded profits. Being prolific and quite mobile the nutria quickly spread through much of western Oregon. By the 1960s damage to agricultural crops was …

Ichthyofaunal Diversification And Distribution In Jane's Creek Watershed, Randolph County, Arkansas, Cheryl Lynn Fowler, George L. Harp

Journal of the Arkansas Academy of Science

The purposes of this study were to determine the qualitative and quantitative distribution of fishes in the Jane's Creek watershed. Jane's Creek is a clear, spring-fed Ozark stream in northeastern Arkansas. A knowledge of the ichthyofauna of this stream prior to a long-range impoundment is of significance to the natural history of Arkansas. Jane's Creek and its tributaries were found to be alkaline, with no measurable turbidity, and to have low levels of carbon dioxide. Dissolved oxygen values ranged from 6.1 to 16.0 ppm. Only slight differences in physicochemical conditions were noted among stations and between pool and riffle areas …

Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

The Effect Of Thermal Increases On The Acute Toxicity Of Copper And Hexavalent Chromium To Channel Catfish (Ictalurus Punctatus), Alan Kirk Millis

Masters Theses

48-hr, 96-hr, and incipient median tolerance limits of channel catfish (Ictalurus punctatus Rafinesque) to copper and hexavalent chromium were determined at temperatures of 50, 60, 70, and 80 F. Standard static bioassay procedures were used. The incipient TLm for copper ranged from 0.56 ppm to 2.15 ppm and from 22.5 to 39.5 ppm for hexavalent chromium. The 48-hr and 96-hr results were somewhat higher. The highest resistance for both metals occurred at 70 F. At 80 F, however, there was a sharp decrease in tolerance. Increased oxygen consumption and opercular movement offer a possible explanation since they would …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …
