RÉSUMÉ. La construction de logiciels à partir de plusieurs applications différentes et hétérogènes est de plus en plus fréquente. Cependant, il n’existe pas à présent une méthodologie de construction pour de tels logiciels. Dans cet article, nous proposons une architecture qui permet de créer des logiciels en faisant collaborer plusieurs services et applications différentes et hétérogènes, util...

Pihlgren, A. 2007. Small-scale structures and grazing intensity in semi-natural pastures effects on plants and insects. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-7312-1. Semi-natural grasslands characterized by nutrient poor soils are among the most species-rich habitats in Europe and they harbour many red-listed species. The area of semi-natural grasslands has decreased drastically du...

A 3-yr experiment was conducted with cows and their calves to evaluate resource inputs, animal performance, and carcass characteristics of two production systems. In the control system, cows (CON; n = 99/yr) grazed pasture and were fed hay during the winter, and CON steer calves were finished in the feedlot for 211 d after weaning. In the treatment system (TRT; n = 100/yr), cows grazed pasture ...

We examined long-term (10 years) meadow plant community responses to (1) livestock grazing under riparian grazing utilization limits; (2) suspension of livestock grazing; and (3) meadow site wetness and precipitation on the Inyo National Forest, California. Observed trends in meadow plant species richness, diversity, and frequency of soil stabilizing species were not significantly different bet...

Tundra plant communities are often shaped by topography. Contrasting wind exposure, slopes of different inclination and landforms curvature affect habitat conditions shape diversity patterns. The majority tundra is also grazed ungulates, which may alter topographically induced patterns, but such effects depend on the spatial scales assessments. Here we ask whether patterns within ( alpha ) betw...

Three methods of copper supplementation were compared in 9to 15-month-old Friesian bulls on a farm with a history of copper deficiency. A group of 60 bulls grazed 19 ha which had been topdressed in May with 120 kg copper sulphate (6.3 kg/ha). Five of the bulls were identified for repeated sample collection. A second group of 60 bulls grazed an untreated area and five of these were each given a ...

Veira, D. M., Lysyk, T. J., Thompson, D. J., Garland, G. J. and Majak, W. 2010. Effect of grazing mixtures of alfalfa and orchardgrass grown in strips on the incidence of bloat in cattle. Can. J. Anim. Sci. 90: 109 112. Steers were grazed on pastures with alfalfa and orchardgrass grown in monoculture strips with alfalfa covering 100, 75 or 50% of the ground area. The forages were maintained at ...

Coproscopic examinations of mouflons Ovis aries musimon from four forest districts of Lower Silesia performed in spring and autumn from 2012 to 2014 demonstrated the presence of pulmonary nematodes and intestinal parasites, including coccidia of the genus Eimeria. Prevalence of pulmonary nematodes (mainly Muellerius capillaris) amounted to 69.78%, intestinal nematodes--56.11% and coccidia of th...

The high and middle intertidal zones of the northeastern portion ("barren") of the limestone bench on the windward side of Enewetak Island, Enewetak Atoll, Marshall Islands, have a significantly higher number of herbivorous fishes grazing at high tide than the same intertidal zones of the reef flat 300 m to the southwest ("algae-covered"). This portion of the reef flat in the barren, heavily gr...
