Working Up Green, and Living Up Green

Amazon forests green-up during 2005 drought.

Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly ...

Green Homeowners as Lead Adopters: Sustainable Living and Green Computing

In this paper, we explore opportunities for green computing, drawing on our ethnographic study of 35 green households in the United States. We begin by discussing recent shifts in Western environmentalism and the growth of green consumerism. We then explore green social networking processes and how these relate to perceptions of corporations, openness to new technological solutions, and our par...

Amazon rainforests green-up with sunlight in dry season

[1] Metabolism and phenology of Amazon rainforests significantly influence global dynamics of climate, carbon and water, but remain poorly understood. We analyzed Amazon vegetation phenology at multiple scales with Moderate Resolution Imaging Spectroradiometer (MODIS) satellite measurements from 2000 to 2005. MODIS Enhanced Vegetation Index (EVI, an index of canopy photosynthetic capacity) incr...

Growing up green: cellular basis of plant development

Plant development is a biphasic process. Pattern formation during embryogenesis generates a basic body organisation, including self-maintaining stem-cell systems called meristems at opposite ends of the main axis of polarity. During post-embryonic development, the meristems produce new organs with reference to the existing body, transforming the juvenile seedling into the species-specific adult...
