| Description: |
Animal populations can have a far more significant effect on carbon storage and exchange in regional ecosystems than is typically recognized by global carbon models, according to a new paper. In fact, in some regions the magnitude of carbon uptake or release due to the effects of specific animal species or groups of animals - such as the pine beetles devouring forests in western North America - can rival the impact of fossil fuel emissions for the same region.
