Soil-borne pathogens drive tree diversity in forests, study shows
Date:6/25/2010

MILWAUKEE What determines plant diversity in a forest? It's a question even Charles Darwin wanted to unravel. But most research into forest diversity demonstrates only patterns of species survival and abundance rather than the reason for them until now.

A team of researchers led by biologists at the University of WisconsinMilwaukee (UWM) has shown that soil-borne pathogens are one important mechanism that can maintain species diversity and explain patterns of tree abundance in a forest.

The paper, "Negative plant-soil feedbacks predict tree-species relative abundance in a tropical forest," is published today in the journal Nature. The lead authors are Scott Mangan, a UWM postdoctoral research associate, and Stefan Schnitzer, UWM associate professor of biological sciences. Other authors include Edward A. Herre and Evelyn I. Sanchez of the Smithsonian Tropical Research Institute, Keenan M.L. Mack and James D. Bever of Indiana University, and Mariana C. Valencia of the University of IllinoisChicago.

In a self-limiting process called "negative feedback," scientists have observed that the farther from the parent tree a seed falls, the better it fares. Negative feedbacks occur when juveniles growing near an adult of the same species are particularly vulnerable to the detrimental effects of enemies that accumulate in the soil near the adult tree.

In both greenhouse and field experiments, the researchers found clues that tree species differ in their susceptibilities to enemies found in the soil, such as viruses, bacteria and fungi.

The research reinforces the conclusion that certain tree species are abundant in forests because they are less susceptible to pathogens in the soil than rarer tree species, says Mangan. "Strong negative feedbacks with soil-borne pathogens prevent rare tree species from becoming abundant."

The study has shown that more abundant tree species exhibit the weakest negative feedback
