TL;DR: It is shown, using data from 854 sites across Africa, that maximum woody cover in savannas receiving a mean annual precipitation (MAP) of less than ∼650 mm is constrained by, and increases linearly with, MAP.
Abstract: Savannas are globally important ecosystems of great significance to human economies. In these biomes, which are characterized by the co-dominance of trees and grasses, woody cover is a chief determinant of ecosystem properties1–3. The availability of resources (water, nutrients) and disturbance regimes (fire, herbivory) are thought to be important in regulating woody cover1,2,4,5, but perceptions differ on which of these are the primary drivers of savanna structure. Here we show, using data from 854 sites across Africa, that maximum woody cover in savannas receiving a mean annual precipitation (MAP) of less than ,650mm is constrained by, and increases linearly with, MAP. These arid and semi-arid savannas may be considered ‘stable' systems in which water constrains woody cover and permits grasses to coexist, while fire, herbivory and soil properties interact to reduce woody cover below the MAP-controlled upper bound. Above a MAP of ,650mm, savannas are ‘unstable' systems in which MAP is sufficient for woody canopy closure, and disturbances (fire, herbivory) are required for the coexistence of trees and grass. These results provide insights into the nature of African savannas and suggest that future changes in precipitation6 may considerably affect their distribution and dynamics.

TL;DR: None of the drug regimens evaluated reduced the rates of HIV-1 acquisition in an intention-to-treat analysis, and adherence to study drugs was low.
Abstract: BackgroundReproductive-age women need effective interventions to prevent the acquisition of human immunodeficiency virus type 1 (HIV-1) infection. MethodsWe conducted a randomized, placebo-controlled trial to assess daily treatment with oral tenofovir disoproxil fumarate (TDF), oral tenofovir–emtricitabine (TDF-FTC), or 1% tenofovir (TFV) vaginal gel as preexposure prophylaxis against HIV-1 infection in women in South Africa, Uganda, and Zimbabwe. HIV-1 testing was performed monthly, and plasma TFV levels were assessed quarterly. ResultsOf 12,320 women who were screened, 5029 were enrolled in the study. The rate of retention in the study was 91% during 5509 person-years of follow-up. A total of 312 HIV-1 infections occurred; the incidence of HIV-1 infection was 5.7 per 100 person-years. In the modified intention-to-treat analysis, the effectiveness was −49.0% with TDF (hazard ratio for infection, 1.49; 95% confidence interval [CI], 0.97 to 2.29), −4.4% with TDF-FTC (hazard ratio, 1.04; 95% CI, 0.73 to 1.4...

TL;DR: The authors examined the impact of pre-school malnutrition on subsequent human capital formation in rural Zimbabwe using a maternal fixed effects - instrumental variables (MFE-IV) estimator with a long term panel data set.
Abstract: This paper examines the impact of pre-school malnutrition on subsequent human capital formation in rural Zimbabwe using a maternal fixed effects - instrumental variables (MFE-IV) estimator with a long term panel data set. Representations of civil war and drought shocks are used to identify differences in pre-school nutritional status across siblings. Improvements in height-for-age in pre-schoolers are associated with increased height as a young adult and number of grades of schooling completed. Had the median pre-school child in this sample had the stature of a median child in a developed country, by adolescence, she would be 3.4 centimeters taller, had completed an additional 0.85 grades of schooling and would have commenced school six months earlier. © 2006 Oxford University Press.
