Kangaroos (Macropus spp., Osphranter spp.) are the most ubiquitous free-ranging herbivores in Australia. Much has been written on their impacts plant community composition and how they interact with livestock, particularly extensive rangelands. Little is known, however, about kangaroos affect soil function relationship healthy soils, nor impact of peri-urban populations where might come into co...

Abstract Many ecosystems are grazed by livestock or large, wild herbivores and exist as mosaics of different vegetation communities. Changing grazing could have an impact on heterogeneity well composition. A long-term, large-scale experiment that maintained existing low-intensity sheep grazing, tripled it, removed it partially substituted cattle was set up a mosaic upland types. The changing re...

The ability of grassland ecosystems to sequester carbon has a great potential achieve neutralization. Rhizosphere deposition is the most uncertain part soil cycle. Since grazing one main ways utilize grasslands, we conducted experiments clarify role rhizosphere on organic (SOC) cycling under in typical steppe region Inner Mongolia, China. experiment was grasslands light, moderate, and heavy con...

Many of the world's rural populations are dependent on the local provision of economically and medicinally important plant resources. However, increasing land-use intensity is depleting these resources, reducing human welfare, and thereby constraining development. Here we investigate a low cost strategy to manage the availability of valuable plant resources, facilitated by the use of isolated F...

Abstract Context A key global challenge is to meet both the growing demand for food and feed while maintaining biodiversity’s supporting functions. Protected grasslands, such as Natura 2000 sites in Europe, may play an important role harmonising productivity biodiversity goals. This work contributes understanding of relationship between forage production plant diversity protected non-protected ...

Between August and October 2000, a cross-sectional study was conducted in smallholder dairy farms in Mbale District, Uganda to assess the prevalence of ticks and tick-borne diseases under different grazing systems and agro-ecological zones and understand the circumstances under which farmers operated. A questionnaire was administered to obtain information on dairy farm circumstances and practic...

Recent epidemiological observations from field studies indicated that sheep selected for resistance to digestive nematodes were more infected than susceptible ones with the nasal bot fly, Oestrus ovis. The present study was undertaken to verify these informations and to explore the possible associated mechanisms. After a whole grazing season and an anthelmintic drench, two groups of 6 rams belo...
