Agricultural intensification reduces ecological resilience of land-use systems, whereas paradoxically, environmental change and climate extremes requi...

Many rangelands evolved under an interactive disturbance regime in which grazers respond to the spatial pattern of fire and create a patchy, heterogen...

Developing methods to use biocrusts in restoration is becoming more important as land use and climate change impact the health and intactness of high-...

In studies on organochlorine residues in lakes of the Rift Valley, Kenya, 47% of the farms surveyed in the Nakuru catchment basin used either DDT or d...

Habitat manipulation is important for enhancing biological control of arthropod pests, but identification of selective food plants that benefit only n...

There are few long-term experimental studies of plant community responses to changes in grazing intensity. Here we report species' changes in a mesotr...

Climate change, in combination with the impacts of land use, will give rise to new opportunities for grassland invasion. This paper reports on the rep...

Disturbance is widely believed to facilitate invasions by exotic plants, but is also important for the persistence of many native species. The results...
