How the Amazon Rainforest Dies 1122 - If somewhere between 20 and 25% of the forest were lost, models suggested, much of the Amazon would perish.  About 18% of the rainforest is now gone, and the evidence increasingly supports the warnings.  Whether or not the tipping point has arrived — and some scientists think it has — the Amazon is beginning to collapse.  More than 3/4 of the rainforest, research indicates, is showing signs of lost resilience.  In fire-scorched areas of the Rio Negro floodplains, one research group noted a “drastic ecosystem shift” that has reduced jungle to savanna.  In the southeastern Amazon, which has been assaulted by rapacious cattle ranching, trees are dying off and being pushed aside by species better acclimated to drier climes.  In the southwestern Amazon, fast-growing bamboo is overtaking lands ravaged by fire and drought.

Large Wild Herbivores May Help Slow Climate Change 1222 - By removing living and dead plants, large animals dispose of material that may fuel wildfires.  By consuming vegetation and excreting dung, they may improve availability of nutrients to plants and support the storage of carbon in vegetation and soil.  By creating gaps in the vegetation and dispersing seeds, they create diverse ecosystems with plenty of opportunities for a variety of plants to grow, making ecosystems more resilient and better able to deal with climate change.  By nibbling down polar region shrubs and trampling snow, large animals help maintain permafrost, helping prevent the release of carbon to the atmosphere.
