Parent Material Which Produces Saline Outcrops As A Factor In Differential Distribution Of Perennial Plants In The Northern Mojave Desert, A. Wallace, E. M. Romney, R. A. Wood, A. A. El-Ghonemy, S. A. Bamberg

Great Basin Naturalist Memoirs

An area of 0.46 km² divided into six zones in the northern Mojave Desert transitional with the Great Basin Desert has been studied. Diversity is high among the perennial plant species within the 0.46 km² area. Common species for the two deserts that are present in the area studied are Atriplex confertifolia (Torr. & Frem.) S.Wats., Ceratoides lanata (Pursh) J. T. Howell, Grayia spinosa (Hook.) Moq., Ephedra nevadensis S. Wats. Some other species present include Lycium andersonii A. Gray, Lycium pallidum Miers, Ambrosia dumosa (A. Gray) Payne., Larrea tridentata (Sesse & Moc. ex DC) Cov., Acamptopappus shockleyi A. …

Transpiration And Co2 Fixation Of Selected Desert Shrubs As Related To Soil-Water Potential, S. B. Clark, J. Letey Jr., O. R. Lunt, A. Wallace, G. E. Kleinkopf, E. M. Romney

Great Basin Naturalist Memoirs

In desert plants, transpiration rates decreased before photosynthetic rates when plants were entering a period of water stress. This may have adaptive consequences. A difference of -5 bars in the soil-moisture potential had considerable importance in reducing the rate of transpiration. In Helianthus annuus L. (sunflower) the photosynthetic rate decreased before the transpiration rate in contrast to Great Basin-Mojave Desert plants, and the changes occurred with a -1 bar difference in soil-moisture potential. Morphological changes in three desert plant species [Artemisia tridentata Nutt., Ambrosia dumosa (Gray) Payne, Larrea tridentata (Ses. Moc. ex DC) Cov.] as the soil-moisture potential decreased …

An Evaluation Of Small Rodent Populations In Four Dismal Swamp Plant Communities, Fiona Elizabeth Breidling

Biological Sciences Theses & Dissertations

Diversity and density of small rodents in the Dismal Swamp are believed to be low. Reasons for this may be excessive predation, heavy interspecific pressure from larger rodents, lack of suitable habitat, low food availability or flooding.

Rodent populations were evaluated using live-traps and pitfall traps in four different Dismal Swamp plant communities. Habitat was compared on the basis of phytomass studies previously reported. Flood levels were recorded during live-trapping sessions. Mast from trees was collected in modified mast collectors, and fed to Peromyscus leucopus in the laboratory. Mast was analyzed for caloric value and nutrient content.

The Effect Of Stress On Livestock And Meat Quality Prior To And During Slaughter, Temple Grandin

International Journal for the Study of Animal Problems

The effects of stress on cattle, pigs and sheep prior to slaughter are reviewed. Long-term preslaughter stress, such as fighting, cold weather, fasting and transit, which occurs 12 to 48 hours prior to slaughter depletes muscle glycogen, resulting in meat which has a higher pH, darker color, and is drier. Short-term acute stress, such as excitement or fighting immediately prior to slaughter, produced lactic acid from the breakdown of glycogen. This results in meat which has a lower pH, lighter color, reduced water binding capacity, and is possibly tougher. Psychological stressors, such as excitement and fighting, will often have a …

Provisional Checklist Of Mammals Of South Dakota, Jerry R. Choate, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Distributional patterns of mammals in South Dakota are among the most poorly known for any region of similar size in temperate North America. The only state-wide treatment of the group was the mimeographed compilation by Over and Churchill (1945), which consisted mostly of nontechnical anecdotes. Consequently, much of what is known of the distribution of South Dakotan mammals has been derived from localized inventories (Findley 1956a on Clay County ; Andersen and Jones 1971 on Harding County; Turner 1974 on the Black Hills; and Wilhelm et al. 1981 on Lacreek National Wildlife Refuge in Bennett County). These studies, supplemented with …

Effect Of Fish Size On Prey Size Selection In Gambusia Affinis, Wayne A. Wurtsbaugh, Joseph J. Cech Jr., James Compton

Watershed Sciences Faculty Publications

Food size selection of the mosquitofish , Gambusia affinis affinis. was measured in aquaria using juvenile stages of the mosquito, Clllex tarsalb;, as prey. Fish size varied from recently born fry to large adult females. Food size selection was positively correlated with fish size. Mosquitofish fry (6-8 111m standard length) attacked and ate primarily first and second instar larvae. Fry attacked larger instars, but attack success on these was low (0 - 50%). Fish larger than 20 mm attached primarily pupae and third and fourth instar larva. No first instar mosquitoes were eaten. Attack success for these fish was above …

Mass Marking Of Mosquitofish: Preliminary Results, Bruce Vondracek, Wayne A. Wurtsbaugh, Joseph J. Cech Jr.

Watershed Sciences Faculty Publications

Three marking techniques were tested to determine their applicability for mosquitofish. Tetracycline drugs and DC Ar administered in the diet successfully marked laboratory-cultured mosquitofish, but exposure to direct sunlight in outdoor tanks resulted in the rapid disappearance of the marks. Preliminary data on fluorescent marks from a polystyrene pigment in a melamine-sulfonamide-formaldehyde resin forced into the dermal ,tissue with compressed air are more promising.

A t an optimal deliver pressure of 7.3 m Hg (140 p.s.i.) and spraying time of 15 sec., marking percentage is maximized and fish mortality is minimized. Mark retention time was up to 80 days in …

A Light And Electron Microscopic Study Of Visual Neurons In The Medulla Externa Of The Crab Hemigrapsus Nudus, Yu Cheng Liao

Loma Linda University Electronic Theses, Dissertations & Projects

The decapod crustacean with a relatively well-defined visual system have contributed significantly to our understanding of visual neuron morphology and physiology. The general morphology of the optic lobes of several decapods were initially described by Parker (1897) and Hanstrom (1924). In the past few years, several light and electron microscope studies have been made on the lamina ganglionaris: the first optic ganglion, of the lobster (Hamori and Horridge, 1966a); the crayfish (Hafner, 1974; Nassel, 1976a), and the crab (Stowe et al., 1977; Rafuse et al., in preparation). As yet, no adequate description has been made of the visual neurons in …

Where Have All The Curlews Gone?, Paul A. Johnsgard

Papers in Ornithology

After a period of limited optimism, ornithologists are again in a state of uncertainty and doubt as to the existence of the elusive Eskimo Curlew. In spite of the ever increasing activities of bird watchers, no sightings have been reported from the Texas coast in the last decade, and the present status of this ill-fated bird is impossible to judge. Most of the persons who have summarized its sad story have come to the conclusion that uncontrolled hunting, particularly spring hunting in the Great Plains, was the single most important factor in its demise. Richard C. Banks of the U.S. …

Sheep Mulesing And Animal Lib, Nancy Heneson

International Journal for the Study of Animal Problems

The practice of mulesing sheep to prevent blowfly strike has recently come under fire from the Animal Liberation movement in Australia. Although it is only one of the many issues which Animal Lib has raised in its campaign to reform various sectors of the livestock industry, it is particularly illustrative of the kinds of conflicts in world view which arise when animal rights activists turn the spotlight on the farming establishment. Spokesmen for the livestock industries are quick to stress the emotional and sometimes sensational portrayal by Animal Libbers of time-honored animal management practices, as well as the sinister role …

Effects Of Supplementary Amino Acids In An All-Corn Diet On The Growth And Metabolic Performance Of Young Rats And Pigs, Dale Alan Grosbach

Open Access Master's Theses (through 2010)

While there is presently an agreement on the status of lysine and tryptophan being closely first and second, or co-limiting, little beyond this is known. Which amino acids are the next limiting, and if they would give an important performance boost is unknown.

The stage of the pig’s growth at which these factors are examined may also be important. Much of the work has been done with larger growing or finishing of pigs. It may be more advantageous to work with pigs that weigh from 10 to 35 kg compared to the 40 to 110 kg animal. It is at …

Correction To 1979 Fall Occurrence Report

Nebraska Bird Review

In the Garden Co. column in the 1979 Fall Occurrence Report Common Goldeneye, Common Merganser, Common Flicker, and Cedar Waxwing were listed with a single date only. Each should have shown "_W" also, since they did stay past 31 December, although they left before the winter was over. Also Bald Eagle, Turkey, Rock Dove, and Starling should have shown a * to indicate that they did winter in the county, although not on the Refuge.

An Analysis Of Migration Schedules Of Non-Passerine Birds In Nebraska, Paul A. Johnsgard

Nebraska Bird Review

AN ANALYSIS OF MIGRATION SCHEDULES OF NON-PASSERINE BIRDS IN NEBRASKA

One of the major components of the Nebraska Bird Review since its inception has been the annual spring migration and occurrence report, and in more recent years the fall occurrence report has become equally important. Yet, other than an uncompleted effort by W.F. Rapp, Jr. to summarize the first 25 years of spring migration data, these records apparently have not been analyzed by anyone. Part of the problem is the sheer mass of data to be assimilated, and a second issue is the question of how to classify certain species, …
