(Reports, 16 March 2012, p. 1344) conclude that niche shifts are rare for terrestrial plant invaders and that this justifies the use of correlative modeling to project species geographic ranges for biological invasions and climate change. We draw attention to the limitations of their conceptual assumptions and the importance of niche shifts excluded from their analyses.
Production and productivity developments in South Africa have regional consequences:
South Africa’s agricultural economy accounted for 43.1% of the agricultural GDP of
This article sets the background for an exciting new linkage between Australian and Africa-based scientists who will use NIR to enhance the safety and value of traditional African crops.
We use newly constructed state-specific data to explore the implications of common modeling choices for measures of research returns.
Insect pests and plant diseases reduce cassava yields substantially, posing a threat to food security throughout the developing world.
The use of mixtures of transgenic insecticidal seed and nontransgenic seed to provide an in-field refuge for susceptible insects in insect-resistance-management (IRM) plans has been considered for at
The twentieth century saw substantive shifts in the structure, funding and conduct of public agricultural research and development (R&D) and related regulatory and extension activities in South Africa.
