Ground control

As the climate warms it will destabilize organic matter in soils, causing an increase in the amount of carbon dioxide that they release into the atmosphere. For forests in temperate regions, four degrees of soil warming for two years increased CO2 emissions by around one-third, but tropical soils were expected to be less sensitive to warming. In this week’s issue, Andrew Nottingham and his colleagues present the results of a soil-warming experiment that challenge this assumption. The researchers conducted a warming experiment on lowland tropical forest soil on Barro Colorado Island in Panama (pictured on the cover). Two years of warming to raise the soil temperature by 4 °C resulted in an unexpectedly large increase in CO2 emissions of 55%. These results suggest that tropical soils are highly sensitive to warming and could present a substantial positive feedback to climate change.

    Stretching the skin of mice reveals that mechanical strain is communicated by a subpopulation of stem cells that proliferate and promote mechanical resistance, and so generate extra skin.

    Plots of tropical forest soils were warmed by 4 °C for two years to observe the effects on soil carbon emissions. The increase in efflux of carbon dioxide was larger than expected — a result with worrying implications for climate change.
