Biodiversity key to sustainable biofuel according to University of Minn. researcher's findings

Ecosystems containing many different plant species are not only more productive, they are also better able to withstand and recover from climate extremes, pests and disease over long periods of time.

These findings, published in the June 1 issue of Nature, are the culmination of 12 years of experiments conducted by David Tilman, Regents Professor of Ecology at the University of Minnesota, to explore the value of biodiversity. The research was carried out at Cedar Creek Natural History Area, near Cambridge, a field station operated by the university's College of Biological Sciences.

"This is exciting because it shows that biodiversity can be used to produce a sustainable supply of biomass for biofuels," Tilman says.

For more than 50 years, scientists have debated the hypothesis that biodiversity stabilizes ecosystems. The University of Minnesota study is the first to provide enough data -- gathered over a sufficient time period in an experiment that controlled biodiversity to confirm the theory. The time period of the study allowed researchers to evaluate the average net effects of diversity on resistance to and recovery from drought, pests, disease and other disturbances. Tilman and his collaborators began the work in the early 1990s and began publishing a series of landmark papers in 1994.

Biodiversity of global ecosystems has decreased as global population has increased because diverse ecosystems such as forests and prairies have been cleared to make way for agricultural fields planted with monocultures, buildings and roads.

Tilman's research has shown that ecosystems containing many different plant species are more productive than those containing only one of those species. A return to biodiversity may prove to be the key to meeting energy needs for the growing number of people on the planet and for restoring global ecosystems.
