Abstract Extract Sir,—We should like to take this opportunity to congratulate Messrs Cordes, Dodd and O'Hara (1964) on their excellent article on bovine mycotic abortion and pneumonia in New Zealand, and at the same time mention certain complementary features of these conditions as noted in Tasmania. 相似文献

Extract Sir, — Diagnostic parasitologists are often required to examine autolysed gastro-intestinal tracts. Such specimens are aesthetically unpleasant and fragmentation of worms may have occurred, making it impossible either to identify or count them. Autolysis often occurs following collection while the specimen is in transit to the laboratory. 相似文献

Abstract Extract Sir, — We wish to record the presence of the tick Rhipicephalus sanguineus on a dog imported from Australia. This tick is mainly parasitic on dogs although on rare occasions it has been collected from non-canine hosts (Roberts, 1965). Experimentally it has been shown capable of transmitting a wide variety of serious diseases but its role as a natural vector of many of them is unknown. In Australia it has been demostrated as being naturally infected with Coxiella burnetii (Smith, 1942) and is recorded from all continents and some oceanic islands lying between latitudes 50°N and 36°S (Roberts, 1970). Auckland falls within this boundaries and therefore it is not unreasonable to suggest that R. sanguineus could become established in New Zealand. 相似文献

Sensitivity of boreal forest carbon balance to soil thaw 总被引:6,自引:0,他引:6
ML Goulden SC Wofsy JW Harden SE Trumbore PM Crill ST Gower T Fries BC Daube S Fan DJ Sutton A Bazzaz JW Munger 《Science (New York, N.Y.)》1998,279(5348):214-217
We used eddy covariance; gas-exchange chambers; radiocarbon analysis; wood, moss, and soil inventories; and laboratory incubations to measure the carbon balance of a 120-year-old black spruce forest in Manitoba, Canada. The site lost 0.3 +/- 0.5 metric ton of carbon per hectare per year (ton C ha-1 year-1) from 1994 to 1997, with a gain of 0.6 +/- 0.2 ton C ha-1 year-1 in moss and wood offset by a loss of 0.8 +/- 0.5 ton C ha-1 year-1 from the soil. The soil remained frozen most of the year, and the decomposition of organic matter in the soil increased 10-fold upon thawing. The stability of the soil carbon pool ( approximately 150 tons C ha-1) appears sensitive to the depth and duration of thaw, and climatic changes that promote thaw are likely to cause a net efflux of carbon dioxide from the site. 相似文献

Shear-wave splitting and implications for mantle flow beneath the MELT region of the east pacific rise 总被引:1,自引:0,他引:1
Shear-wave splitting across the fast-spreading East Pacific Rise has been measured from records of SKS and SKKS phases on the ocean-bottom seismometers of the Mantle Electromagnetic and Tomography (MELT) Experiment. The direction of fast shear-wave polarization is aligned parallel to the spreading direction. Delay times between fast and slow shear waves are asymmetric across the rise, and off-axis values on the Pacific Plate are twice those on the Nazca Plate. Splitting on the Pacific Plate may reflect anisotropy associated with spreading-induced flow above a depth of about 100 km, as well as a deeper contribution from warm asthenospheric return flow from the Pacific Superswell region. 相似文献
