Most plant species important in various and varying ecosystems: ISU research

AMES, Iowa From the kinds that people sneeze at, to the kinds that have prickly seeds that stick to pant legs, there are many different types of plants in grasslands around the world.

According to a new analysis of plants in grassland ecosystems around the world, it turns out that most of those plant species are important.

Brian Wilsey, associate professor, and Stanley Harpole, assistant professor, both in Iowa State University's Department of Ecology, Evolution and Organismal Biology, are authors of a study on plant diversity published in today's issue of the journal Nature. The study's lead author, Forest Isbell, is a former graduate student of Wilsey who now works at McGill University, Canada.

Their findings show that most species promoted ecosystem functioning in at least some years, sites and environmental conditions. In all, 84 percent of the grassland species are important to the ecosystem at some point.

Prior to this multi-year, multi-context research, Wilsey said that the argument for diversity was more difficult.

"In any single context, only about 27 percent of plant species were seen as important," he said.

Since previous research had shown that such a small number of plant species were important to ecosystem processes, there was less reason to be concerned if grasslands lost different species and diversity lessened, according to Wilsey.

Now, the value of diversity is very apparent.

The species needed to provide one function during multiple years were not the same as those needed to provide multiple functions within one year, the report said.

"If you look at any one year at one site, you might say that species A or species B are really important," said Wilsey. "But what we found was that if you run the analysis over several years, sites or environmental-change contexts, many different species become important. This study really brought everything together."
