Stability of African pastoral ecosystems: alternate paradigms and implications for development
JIM ELLIS took undergraduate work in animal husbandry at the University of Missouri and also obtained his Master of Science degree there studying wildlife biology. In 1970, he received his Ph.D. in
Climate Patterns and Land-Use Practices in the Dry Zones of Africa
This article discusses the following two areas in depth: precipitation patterns and land use including temporal precipitation patterns, seasonality, interannual variability, and long term trends.
Plant-herbivore interactions in a North American mixed-grass prairie
It is suggested that prairie dog-induced changes in plant biomass, plant species diversity, plant nutrient content, and forage digestibility may lead to further alterations of nutrient cycling and trophic dynamics in this mixed-grass prairie ecosystem.
Impacts of Pastoralists on Woodlands in South Turkana, Kenya: Livestock‐ Mediated Tree Recruitment
The early survival and growth advantages of the corral environment appear to stabilize the reproductive patterns of A. tortilis in this arid ecosystem, where successful recruitment in noncorral sites may be restricted to the few years with high rainfall.
Regional analysis of climate, primary production, and livestock density in inner Mongolia.
There was a significant linear relationship between annual rainfall and ANPP in IMAR and the slope of ANPP versus rainfall was greater than those found in South America and Africa, indicating higher rain-use efficiency.
Landscape and climatic control of woody vegetation in a dry tropical ecosystem: Turkana District, Kenya
The spatial organization of a dry woodland/ savanna/shrub-steppe ecosystem in a 9000 km2 region of arid Northern Kenya was explored by analysing the abundance and distribution of woody vegetation in
