Classical ecological theory predicts that changes in the availability of essential resources such as nitrogen should lead to changes in plant community composition due to differences in species-specific nutrient requirements. What remains unknown, however, is the extent to which climate change will alter the relationship between plant communities and the nitrogen cycle.

A proposal to let nations opt out of growing European-approved GM varieties is under fire from all sides.

Over the past decade, several models have been developed to predict the
impact of climate change on biodiversity.
