Abstract:
... The successful interaction amongst relevant stakeholders in water and climate management in Africa is of principal importance when trying to address local water challenges and provide effective solutions. Yet there was no mechanism in place to know who has the information, which organisations are the bridges, and which are the bottlenecks to water and climate change knowledge exchange. The AfriAll ...

Abstract:
... Habitat for tigers and many carnivores is fragmented and degraded to an extent that the existing land base supporting discrete tiger populations is often inadequate to maintain viable populations. Using fine-scale location data of dispersing tigers, we studied their exploratory movements in Thailand’s Western Forest Complex (WEFCOM), where the last remaining viable tiger population in mainland Sou ...

Abstract:
... Obligate intracellular parasites have evolved a remarkable assortment of strategies to scavenge nutrients from the host cells they parasitize. Most apicomplexans form a parasitophorous vacuole (PV) within the invaded cell, a replicative niche within which they survive and multiply. As well as providing a physical barrier against host cell defense mechanisms, the PV membrane (PVM) is also an import ...

Abstract:
... Corn farmers reported unexpectedly severe damage on fields planted with genetically‐engineered rootworm‐resistant (Bt‐CRW) corn seeds during the 2009 growing season. Entomologists later determined that rootworms on these fields had developed resistance to the insecticidal proteins produced by Bt‐CRW corn. This article explores what corn farmers' seed and soil insecticide choices imply about rootwo ...
