When grasslands are fertilized their productivity is increased, but their plant diversity is diminished, according to Prof. Andrew Hector, Institute of Environmental Sciences, University of Zurich.
In the last 50 years, levels of plant-available nitrogen and phosphorous have doubled worldwide. This additional supply of plant nutrients is predicted to be one of the three most important causes of biodiversity loss in this century, says Hector.
For the first time, the research, under the leadership of Professor Hector, shows the exact mechanisms that lead to the loss of biodiversity from grasslands following fertilization. Read more . . .
