Developing a macroecology for human‐altered ecosystems
Ecography, EarlyView.Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Integration of biotechnologies for rubber tree improvement. What about rootstock clones ?
, 2008 Breeding and dissemination of planting material for rubber plantations are closely linked to propagation methods. Since the progress made by shifting from multiplication by seed to propagation by budding, the development of new techniques, such as ...

Comparison of photosynthesis and antioxidant performance of several Citrus and Fortunella species under natural chilling stress : S08P24 [PDF]
, 2012 Citrus plants originate from southeastern Asia, in a large area with various climates characterized by a broad range of temperatures. Temperature is assumed to be a key factor in Citrus species adaptation and diversification.

Tropical forests and global atmospheric change: a synthesis [PDF]
, 2004 We present a personal perspective on the highlights of the Theme Issue 'Tropical forests and global atmospheric change'. We highlight the key findings on the contemporary rate of climatic change in the tropics, the evidence--gained from field studies--of

Ecography, EarlyView.Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

Unraveling drought propagation dynamics using causal inference from time series
Environmental Research LettersDrought is a pervasive natural hazard that propagates through the hydrologic cycle, leading to water deficiencies across key hydroclimatic variables such as precipitation, streamflow, and soil moisture.

Energy Science &Engineering, EarlyView.Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...
