Serum samples collected from Iberian red deer (Cervus elaphus hispanicus; n=472), fallow deer (Dama dama; n=293) and European wild boar (Sus scrofa; n=174) in Asturias, Northern Spain, from 1999 to 2005 were examined for antibodies against a reference panel of 14 Leptospira spp. serovars. Positive antibody titres at a microscopic agglutination test cut-off of 1:80 were detected against serovars...
at present, most of iran is free of bovine tuberculosis (tb). the strategy of control and eradication in iran involves a tuberculation test and slaughter of reactors, a procedure transformed the present-day prevalence of tb into a sporadic occurrence. this paper describes the first report of bovine tuberculosis in a european fallow deer ( dama dama dama ) in iran. the deer was emaciated and fou...
Although Lands' cycle was discovered in 1958, its function and cellular regulation in membrane homeostasis under physiological and pathological conditions remain largely unknown. Nonbiased high throughput metabolomic profiling revealed that Lands' cycle was impaired leading to significantly elevated erythrocyte membrane lysophosphatidylcholine (LysoPC) content and circulating and erythrocyte ar...
The agricultural use of land resources in the dry steppe regions Northern Kazakhstan has undergone significant changes over past century and continues to change at present time. middle position region is occupied by Akmola region, one leading regions, where 9.3 % country’s gross output produced. main branches agriculture are grain farming dairy beef cattle breeding. study ratio areas arable pas...
The goal of this study was to map rainfed and irrigated rice-fallow cropland areas across South Asia, using MODIS 250 m time-series data and identify where the farming system may be intensified by the inclusion of a shortseason crop during the fallow period. Rice-fallow cropland areas are those areas where rice is grown during the kharif growing season (June–October), followed by a fallow durin...
ABSTRACT We examined the growth and survival of Brazil-nut trees, Bertholletia excelsa (Lecythidaceae) under different environmental conditions levels canopy openness within experimental plantations in Trombetas River valley, northern Brazil. planted 144 seedlings three anthropogenic habitats with sunlight exposition: crop field (100% opening), shrub fallow (20-80% opening) forest (< 10% ope...
In recent years, regulatory agencies in the USA and Europe have begun to require documentation that land used produce crops biofuels has not been converted from carbon-capturing grasslands or forests. Precise measurement of these cover changes, however, proven difficult. Analysis date focused primarily on moderate resolution (30 m) satellite imagery, which provided granularity accuracy needed. ...
No-till dryland winter wheat (Triticum aestivum L.)-fallow systems in the central Great Plains have more water available for crop production than the traditional conventionally tilled winter wheat-fallow systems because of greater precipitation storage efficiency. That additional water is used most efficiently when a crop is present to transpire the water, and crop yields respond positively to ...
