Much recent attention has focused on the potential of trees and forests to mitigate ongoing climate change by acting as sinks for carbon. While our study is restricted to New World trees, we suggest that plant biodiversity globally may be evolutionarily structured following a tropics-extratropics pattern, while diversity within the tropics may be structured primarily around a moist-dry pattern. But trees aren’t immune to disease outbreaks either, and ash trees are facing their own pandemic.

Wohlleben cites the work of Japanese marine chemist Katsuhiko Matsunaga, who discovered that trees falling into a river can change the acidity of the water and thus stimulate the growth of plankton — the elemental and most significant building block of the entire food chain, on which our own sustenance depends. So, these were not stones, after all, but old wood. Most trees grow to a considerable height, usually bearing lateralbranches at some distance from the ground. Decision trees are the foundat i on of the most well performing algorithms on Kaggle competitions and real-life. To practice some observation and identification (both good, solid science skills! The exhibit will run through January 2013. These relationships, Wohlleben points out, are encoded in the forest canopy and visible to anyone who simply looks up: The average tree grows its branches out until it encounters the branch tips of a neighboring tree of the same height.
