Species loss linked to unstable production of grassland ecosystem

Losing plant species is directly linked to long-term declines in the stable productivity of grasslands, a new study has shown. The study demonstrates for the first time that for every decrease in plant biodiversity there is a proportional decrease in the stable production of plant biomass through time of grassland ecosystems. Over the long-term, factors such as rising levels of carbon dioxide, nitrogen, more frequent grazing, or drought, only affect ecosystem stability in as much as they affect biodiversity.
