Journal of Biogeography, La Boussole, Grenoble, France, pages. L’Harmattan, Paris, pages.

Land degradation in north-western Jordan: Growth inhibitory alkaloids from mesquite Prosopis juliflora Sw. Journal of Arid Environments CNRS, Paris, pages. Biodiversity and Conservation Especially, facilitation between plants, and related nurse effects, can be taken as a relevant tool to restore degraded ecosystems in arid environments. Global Change Biology doi: Forest Ecology and Management Vivre dans les milieux fragiles: Animal Feed Science and Technology It is populated with approximately inhabitants depending mostly on local vegetation resources.

Two types of effects are distinguished. Broad-scale satellite Normalized Difference Vegetation Index data predict plant biomass and peak date of nitrogen concentration in Arctic tundra vegetation. Kluser Tchintoulous, et F.

Second, the peripheral urban zones have a growing negative impact on vegetation, especially on wood. Is facilitation in arid environments the result of direct or complex interactions? Effects of rainfall, wild herbivores and change in land use. Co-management plans on natural resources including local inhabitants as managers should break this degradation cycle. Investigations with local populations and empirical observations showed a rapid degradation of the vegetation related to human activities.


Frontiers in Ecology in the Environment 4: Climate sensitivity of shrub growth across the tundra biome. Ward Hunt Island and vicinity. We aimed to study the relationships between the recent changes in human activities and the level of vegetation resource so as to anticipate a possible lack of resources in an arid region confronted to recurrent droughts.

Regional perspectives on exologie and biodiversity in the drylands of Africa. First, local people increase pressure on vegetation around the villages, while the intensification of irrigated agriculture threatens the level of belowground water resources.
