BACKGROUND AND AIMS Understanding the introduction history of invasive plant species is important for their management and identifying effective host-specific biological control agents. However, uncertain taxonomy, intra- and interspecific hybridization, and cryptic speciation may obscure introduction histories, making it difficult to identify native regions to explore for host-specific agents....

The views expressed in this report are those of the authors, and do not necessarily reflect those of the Bill and Melinda Gates Foundation. Summary Exposure to a high degree of climate risk is a characteristic feature of rainfed agriculture in the drylands of sub-Saharan Africa and parts of South Asia. A growing body of evidence l...

Topography in East Nusa Tenggara Province dominate by dryland and slope land. In the farmers develop farming system of maize as a staple crop. Dryland potential for food crop Bali reach 645,891 ha but have low fertile productivity maize. Productivity only 2.7 ton/ha. This is lower if compare with average national level result research. The objective research to get specific technology cultivati...

An advection–diffusion model of fluvial processes was used to analyze the stratigraphic expression avulsions in terminal river systems and understand their control on basin-fill architecture. The initial boundary conditions runs (i.e., catchment area, smoothed topographic surface, grain-size distribution sediment supply rates) were extracted from modern Rio Colorado dryland system Altiplano Bas...
