An Evaluation Of The Endocrine Response To Dystocia In The Primiparous Cow And Calf, Glenda M. Borcher
An Evaluation Of The Endocrine Response To Dystocia In The Primiparous Cow And Calf, Glenda M. Borcher
Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research
Parturition is a very stressful event for both the cow and the calf. Endocrine changes occur which typically enable to calf to make the transition from a uterine to a gaseous environment. These endocrine changes are basic stress responses, necessary for an organism to maintain homeostasis. They include surges in catecholamine and cortisol secretion and changes in T3 secretion in response to temperature changes. It is well established that the stress response, if
prolonged, can become detrimental. Prolonged stress can result in muscle wasting, immune impairment and gastrointestinal ulceration. If parturition is delayed or particularly stressful due to environmental factors …

Temporal And Spatial Dietary Variability In The Prehistoric Lower And Middle Osmore Drainage: The Carbon And Nitrogen Isotope Evidence, Karin L. Sandness
Department of Anthropology: Theses and Student Research
Skeletal material from six sites representing human occupation in the Osmore drainage of southern Peru, circa A.D. 50 to 1400, was analyzed for carbon and nitrogen isotopes. The δ13C and δ15N values observed in the study indicate-spatial and temporal variability in diet. Specimens from the lower valley are, in general, more positive in both carbon and nitrogen than those of the middle valley, with the most positive values being present in specimens from the coastal Chiribaya site, San Geronimo. The data suggest, however, that all populations in the drainage experienced shifts in diet through time. Samples …

Lipoxygenase Inhibitors Shift The Yeast/Mycelium Dimorphism In Ceratocystis Ulmi, Ellen C. Jensen, Clyde Ogg, Kenneth W. Nickerson
Lipoxygenase Inhibitors Shift The Yeast/Mycelium Dimorphism In Ceratocystis Ulmi, Ellen C. Jensen, Clyde Ogg, Kenneth W. Nickerson
Papers in Microbiology
The yeast-mycelium dimorphism in Ceratocystis ulmi, the causative agent of Dutch elm disease, was switched by gossypol, nordihydroguaiaretic acid, and propylgallate. In each case the mycelial form was converted to the yeast form. These compounds are recognized lipoxygenase inhibitors. Inhibitors of cyclooxygenase and thromboxane synthetase did not cause mycelia to shift to the yeast form. We suggest the following two-part hypothesis: (i) that lipoxygenase is a target for antifungal antibiotics and (ii) that many phytoalexins (antimicrobial compounds of plant origin) are targeted toward fungal lipoxygenases. In addition, in a study to determine potential lipoxygenase substrates, a fatty acid analysis …

Problems With Management Of A Native Predator On A Threatened Species: Raven Predation On Desert Tortoises, William I. Boarman
Problems With Management Of A Native Predator On A Threatened Species: Raven Predation On Desert Tortoises, William I. Boarman
Vertebrate Pest Conference Proceedings: 15th (1992)
Common ravens (Corvus corax) are a major predator on the threatened desert tortoise (Gopherus [=Xerobates] agassizii). Large numbers of juvenile tortoise shells have been found beneath known raven nests and perches; many shells that show evidence consistent with raven predation have been found sporadically throughout the range of the tortoise; significant proportional decreases in juvenile size/age class distributions have been identified; and people have observed ravens killing, carrying, and consuming juveniles. In 1988 the U. S. Bureau of Land Management initiated a process to evaluate, design, and implement a program to reduce raven predation …

Nonlethal Repellents: The Development Of Cost-Effective, Practical Solutions To Agricultural And Industrial Problems, J. Russell Mason, Larry Clark
Vertebrate Pest Conference Proceedings: 15th (1992)
Repellents substances and devices cause pest species to avoid otherwise attractive or palatable materials. For birds, repellents can be visual, auditory, pyrotechnic, tactile, chemosensory, physiologic, or physical. Here, we consider chemical agents only. Few substances are registered with the U.S. Environmental Protection Agency (EPA), and thus legally available for use. This lack of available bird repellent technology reflects the small demonstrable economic impact of many agricultural bird damage problems. Accurate information about damage and market size is virtually nonexistent, and private companies are reluctant to invest resources in the unknown. To successfully commercialize new repellents, clearly lucrative markets must be …
Calciferols And Bait Shyness In The Laboratory Rat, C.V. Prescott, Vusa El-Amin, R.H. Smith
Calciferols And Bait Shyness In The Laboratory Rat, C.V. Prescott, Vusa El-Amin, R.H. Smith
Vertebrate Pest Conference Proceedings: 15th (1992)
Rodenticides with delayed action are generally more effective than fast-acting compounds because of the phenomenon of bait shyness. Calciferols have a stop-feed effect quite soon after dosing, and physiological effects are measurable within one day of dosing. We investigated whether bait shyness might result from these fairly rapid effects in the laboratory rat. We found evidence of bait shyness following recovery from sub-lethal dosing with two forms of calciferol. Use of intubation as well as feeding showed that the response was to the bait carrier rather than to detection of calciferols per se.
Operational Application Of Diversionary Food In Young Lodgepole Pine Forests To Reduce Feeding Damage By Red Squirrels, Thomas P. Sullivan
Operational Application Of Diversionary Food In Young Lodgepole Pine Forests To Reduce Feeding Damage By Red Squirrels, Thomas P. Sullivan
Vertebrate Pest Conference Proceedings: 15th (1992)
The use of diversionary food is an ecological method to reduce feeding damage by wildlife to forest and agricultural crops. The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of young lodgepole pine (Pinus contorta var. latifolia) and this damage is particularly severe in intensively managed stands. Aerial application of sunflower seed on an operational scale significantly reduced damage by squirrels. This result was achieved in three different ecological zones in the interior of British Columbia, Canada. The food shortage apparently experienced by these rodents during the May-June damage period can be accommodated by an …
The Starling In Europe: Multiple Approaches To A Problem Species , Chris J. Feare, Pierre Douville De Franssu
The Starling In Europe: Multiple Approaches To A Problem Species , Chris J. Feare, Pierre Douville De Franssu
Vertebrate Pest Conference Proceedings: 15th (1992)
In Europe, Starlings are widely distributed and comprise both resident and migrant populations. These cause various kinds of damage which varies with the crops grown in different European Economic Community (EEC) countries. Although EEC member states are governed by the same legislation on bird protection, each state interprets the Community legislation in its own national legislation. This leads to different national approaches to the prevention of Starling damage, with little information exchange between member states. The establishment of an EEC (or wider) working group on bird pests is recommended to coordinate research and development.

In Situ Ruminal Protein Degradation Of Switchgrass And Smooth Bromegrass, J. J. Mullahey, Steven S. Waller, K. J. Moore, Lowell E. Moser, Terry J. Klopfenstein
In Situ Ruminal Protein Degradation Of Switchgrass And Smooth Bromegrass, J. J. Mullahey, Steven S. Waller, K. J. Moore, Lowell E. Moser, Terry J. Klopfenstein
Department of Agronomy and Horticulture: Faculty Publications
Performance of livestock grazing warm-season, perennial grasses is generally greater than would be expected given their relatively low protein concentrations. Two experiments were conducted to assess ruminal escape protein using an in situ rumen technique for switchgrass (Panicum virgatum L.) and smooth bromegrass (Bromus inennis Leyss.). Whole-plant, leaf, and stem samples were harvested at specific stages of maturity in 1987. Duplicate samples of each grass were incubated for 12 h in situ. Escape protein values were expressed as concentration [grams escape protein per kilogram dry matter (DM) adjusted for acid detergent insoluble nitrogen (ADIN)] and as a percentage …
Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.
Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.
School of Natural Resources: Faculty Publications
The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

G92-1120 Fire Blight Of Apple, Pear And Woody Ornamentals, John E. Watkins
G92-1120 Fire Blight Of Apple, Pear And Woody Ornamentals, John E. Watkins
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide tells how fire blight is spread among apple, pear and woody ornamentals. It describes the disease cycle and offers advice for treatment and protection.
Fire blight, caused by Erwinia amylovora, is the oldest, most serious bacterial disease of apple and pear. It was first reported in the late 18th century in the Hudson River Valley in New York. The disease is indigenous to North America, and probably occurred on native American plants such as crabapple, hawthorn and mountain ash and then spread to susceptible cultivated apples, pears and woody ornamentals planted by the early American pioneers. As …
