Use Of Water By Piglets In The First Days After Birth, David Fraser, P. A. Phillips, B. K. Thompson, W. B. Peeters

Ontogeny Collection

Use of drinking water was determined for 51 litters of piglets by weighing and refilling a water dispenser each day for the first 4 d after farrowing. Measures of spillage, evaporation, and piglet drinking behavior indicated that most disappearance of water represented actual drinking by the piglets. Water use varied greatly among litters with an average of 46 g d^‒1 per piglet over the 4 d, and a range of negligible use to about 200 g d^‒1. Water use, especially on day 2, was correlated negatively with the average weight gain of the litter during the first …

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller

Great Basin Naturalist

Thirty-eight accessions of 20 taxa (species and subspecies) of Chrysothamnus from a range of environments were grown in a uniform garden. During mid-June, terminal and lateral leaves were removed, fixed, and processed for light-microscopy studies. Area and perimeter measurements of ink tracings of midleaf vein cross sections were measured using computer-scan techniques. Leaf area and perimeter were compared with vein perimeter and area measurements. Area and perimeter of these Chrysothamnus leaves varied in response to the environment at the collection location. Plants native to hot, dry conditions had small, thick leaves, whereas plants native to cooler, more mesic conditions had …

Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside

Animal production and livestock published reports

The role of the Rangeland Management Branch is to promote the sustained economic use of the rangeland resource. It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …

Comparative Analysis Of The Effects Of Visual And Auditory Stimuli On Avian Mobbing Behavior, C. Ray Chandler, Robert K. Rose

Biological Sciences Faculty Publications

Both visual and auditory stimuli elicit avian mobbing behavior, but there is little comparative information on their isolated and additive effects. Using three combinations of two experimental stimuli (mount and tape of an Eastern Screech-Owl, Otus asio) we tested the effects of stimuli on the frequency, intensity, and duration of avian mobbing behavior. Of 169 mount-only trials, only 11 (6.5%) were successful in attracting birds. Tape-only (n = 169) and mount-and-tape (n = 170) were equally successful in attracting birds (approximately 85% of all trials), but mount-and-tape trials were more likely to initiate mobbing behavior. Birds responding …

A Light And Electron Microscopic Study Of The Rat Olfactory Tubercle: Normal Morphology And Acetylcholinesterase Localization, James Curtis Woodley

Biological Sciences Theses & Dissertations

A cytoarchitectural analysis of the rat olfactory tubercle using Nissl-stained coronal sections revealed that the dense cell layer (DCL) consisted of medium sized striatal cells in the cortical regions and small sized "granule" cells in the cap regions. Also delineated from this experiment was a rim of neuropil, nearly devoid of neurons as well as neuronal processes, outlining the islands of Calleja. Acetylcholinesterase (AChE) localization utilizing light microscopy revealed that the olfactory tubercles (OT) contained AChE-positive fibers that were orientated dorsoventrally in the molecular and multiform layers. The DCL consisted of only fibers en passant and putative terminals. Diisopropylfluorophosphate (DFP) …

Fisheries Management Paper No. 15 - Draft Management Plan For The Control Of Barramundi Gillnet Fishing In The Kimberley., R. S. Brown

Fisheries Management Papers

This management plan sets out a number of options for the control of commercial gillnet fishing for barramundi in the Kimberley. the plan focuses on existing commercial fishery, and on the fishermen consulted during the process of developing these management arrangements. However, the barramundi stocks of the region are increasingly exploited by large numbers of both local and tourist recreational fishermen whose needs must also be catered for. Because recreational fishermen are not easily identified or contacted as a group, I have endeavoured in this foreword, to set out the management options which best take into account the future needs …

Economics And Marketing Of Western Australia Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

The 1986/87 Australian catch was about 8,300 tonnes. At present levels of fishing,it has been suggested that this could be substantially increased. The fishery is not in danger of over-exploitation. Rather, the problem could be that there is more fish available than existing markets could absorb. However, there are prospects for increasing the present volume of fish sold domestically and for developing new products and markets in Australia and overseas.

Two Species Of Marsh Wren (Cistothorus Palustris) In Nebraska, Donald E. Kroodsma

Nebraska Bird Review

The consequences of a grand evolutionary experiment are evident throughout Nebraska. During the Pleistocene, many taxa were apparently separated into eastern and western populations. Today many of these eastern and western counterparts meet in the Great Plains, especially in Nebraska. Some pairs now hybridize freely (towhees. orioles. flickers), while others do not (buntings, grosbeaks, meadowlarks) (see Rising 1983).

The Marsh Wren is still another, previously unrecognized, taxon that consists of an eastern and western counterpart. Data from Nebraska and elsewhere in North America suggest that there are two forms of the Marsh Wren, perhaps as vocally different from each other …

Department of Animal Science: Faculty Publications

This book, by a well-respected senior lecturer in animal genetics, contains everything a veterinarian is likely to need to know about genetics, and more. The coverage is comprehensive, with emphasis on the interplay of biology and the environment with genetics. Important areas of population and quantitative genetics are treated as non-mathematically as possible, with more complete development available in extensive appendixes.

The Occurrence Of Fish Remains In Modern Lake Systems : A Test Of The Stratified-Lake Mode, Douglas R. Britton

Loma Linda University Electronic Theses, Dissertations & Projects

Theories regarding the taphonomy of fishes in lacustrine environments have traditionally relied on an anoxic water column to explain the excellent preservation. This concept has never been directly tested in modern lacustrine environments that are thought to be analogous to the lacustrine environments predicted by the Stratified-lake Model. This research tested that model by searching for fish remains in 38 collected bottom samples of six modern lacustrine analogues, including Fayetteville Green Lake, New York. The bottom sediments of a warm, holomictic, shallow, and saline lake (Salton Sea, California) were also examined. Although laminated sediments were found in all of the …

Echinococcus Vogeli Rausch And Bernstein, 1972, From The Paca, Cuniculus Paca L. (Rodentia: Dayproctidae), In The Departamento De Santa Cruz, Bolivia, Scott Lyell Gardner, Robert L. Rausch, Otto Carlos Jordan Camacho

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16° 36' W; long. 62° 42' S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges …

Characterization Of The Aquatic Environment In Lake Mead Near The Proposed Spring Canyon Pumped-Storage Project, And Assessment Of Potential Aquatic Impacts, Charles R. Liston, Stephen J. Grabowski, Bureau Of Reclamation

Publications (WR)

A pumped storage system consists of an upper reservoir and lower reservoir separated by an elevation difference. During low demand energy periods such as nights and weekends water is pumped from the lower to the upper reservoir using available energy from conventional steam electric power plants. During high energy demand periods, such as mornings and afternoons of weekdays, upper reservoir water is allowed to drop back down through the same system of water conduits and turbines, generating electricity to conveniently meet abrupt electrical energy requirements. The same water turbines thus act both as pumps and as conventional hydroelectric turbines. Because …

Histology Of The Ovaries And Fat Bodies Of Chthonerpeton Indistinctum, Rafael O. De Sá, Nibia Berois

Biology Faculty Publications

Histological analysis revealed three different stages in the development of ovarian follicles of Chthonerpeton indistinctum. These stages are identified by (1) location of the oocyte in the ovary wall, (2) oocyte morphology and staining characteristics, (3) development of the zona pellucida, and (4) organization of the follicular layer. Atretic follicles and corpora lutea also were found. Fat bodies are composed of well-developed adipose tissue.

Luteinizing Hormone An Progesterone Response To Gnrh Administration At Insemination In Repeat-Breeder Holstein Cows, Robert Joseph Callan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several studies suggest that the administration of GnRH near the time of insemination improves pregnancy rates in cattle. It has also been reported that there is greater improvement in repeat-breeder animals than at first service. The mechanism for this observation has not been established. Twenty-eight lactating Holstein cows that returned to estrus after one or more inseminations from the USU Caine Dairy were used in the study. Animals were randomly divided into two treatment groups, intramuscular administration of 100 ug GnRH or saline control at the time of insemination. Blood samples were collected at 1, 1.5, 2, 2.5, 3 and …
