Cholecalciferol-induced bait shyness in possums (Trichosurus vulpecula)     

David R. Morgan  Lynne Milne 《国际虫害防治杂志》2013,59(2):113-119

Cholecalciferol (vitamin D₃) is used in a variety of bait formulations to control populations of the brushtail possum (Trichosurus vulpecula), an introduced pest that seriously damages and threatens primary production and native biota in New Zealand. In cage trials, possums readily ate sublethal baits containing either an estimated LD₁₅ or LD₄₀ dose of cholecalciferol, leading to a depression of appetite that lasted for 7-15 days. When lethal quantities of baits were presented 21-30 days after the initial LD₁₅ or LD₄₀ baits, 40 and 88% of possums survived, respectively, compared with a 21% survival rate among naive possums, and bait consumption was also reduced among survivors of the initial baits. Subsequent switching of the bait base to a gel was partially successful in overcoming bait shyness, killing 40% of one group (formed by pooling the original groups), while switching both the bait type (to gel) and the toxicant (to 1080) resulted in a 63% mortality rate in a second group. By comparison, 95 and 100% of naive groups were killed by cholecalciferol and 1080 gel respectively. Practical measures are identified for both avoiding and overcoming bait shyness based on the use of alternative bait types and toxicants.  相似文献   

Lactate dehydrogenase isoenzymes in the lungs of sheep with acute and chronic pneumonia     

E M Milne  D L Doxey 《Veterinary research communications》1984,8(3):211-216

Total lactate dehydrogenase and the absolute and percentage levels of its isoenzymes were measured in lung lesions and macroscopically normal areas of lung from lambs with chronic proliferative exudative pneumonia and acute pasteurella pneumonia. Lung lesions had a higher total enzyme activity which was associated mainly with increases in the activity of the LDH4 and LDH5 isoenzymes, particularly in chronic pneumonia, and gave lung lesions a considerable potential for altering the serum isoenzyme distribution. Thus, the nature of any changes in the serum isoenzyme distribution will depend on whether the isoenzymes are released from abnormal or normal areas of lung. This appears to be the first report on lactate dehydrogenase isoenzymes in ovine pneumonia.  相似文献   

Indices of landscape pattern   总被引：171，自引：1，他引：170

Landscape ecology deals with the patterning of ecosystems in space. Methods are needed to quantify aspects of spatial pattern that can be correlated with ecological processes. The present paper develops three indices of pattern derived from information theory and fractal geometry. Using digitized maps, the indices are calculated for 94 quadrangles covering most of the eastern United States. The indices are shown to be reasonably independent of each other and to capture major features of landscape pattern. One of the indices, the fractal dimension, is shown to be correlated with the degree of human manipulation of the landscape.  相似文献

A method for flunixin detection in equine serum extracts involving thin layer chromatography, spraying the chromatogram with alkaline sodium hypochlorite solution and heating with a detection limit of 50 ng ml-1 is described.  相似文献   

FLUOROSCOPICALLY GUIDED PERCUTANEOUS FINE-NEEDLE ASPIRATION BIOPSY OF THORACIC LESIONS IN DOGS AND CATS     

Marjorie C.  McMillan  DVM  Lawrence J.  Kleine  DVM  MS  James L.  Carpenter  DVM 《Veterinary radiology & ultrasound》1988,29(5):194-197

Forty-eight fine-needle aspiration biopsy specimens of intrathoracic lesions were obtained with a Westcott needle by localizing needle placement using TV-monitored, image-amplified fluoroscopy and by detecting changes in tactile sensation. Thiryt-five lesions were pulmonary in origin and 13 were within the mediastinum. Most biospy specimens were obtained with the patients sedated, however, general anesthesia was used in one patient to prevent movement that could have resulted in puncture of a critical structure. The only clinical and radiographic complication from this procedure was pneumothorax, occurring in eight dogs and resulting in one death. Definitive diagnoses were made from tissue obtained from 37 of the 48 lesions sampled for a sensitivity rate of 77.1%. Fine-needle aspiration biopsy was found to be a simple, safe, and accurate diagnostic technique.  相似文献

Regulatory structure for biotechnology proposed     

Sun M 《Science (New York, N.Y.)》1985,227(4684):274

Federal plans to regulate the biotechnology industry have been published by the White House Office of Science and Technology Policy in the 31 December 1984 Federal Register. The report describes how the Environmental Protection Agency, the Food and Drug Administration, and the Department of Agriculture intend to use current laws and guidelines to regulate the new field of genetic engineering. It also proposes that these agencies and the National Science Foundation set up review groups similar to the Recombinant DNA Advisory Committee of the National Institutes of Health. The committees would report to an interagency board that would monitor scientific and regulatory consistency and address broad policy issues.  相似文献
