Study: Climate warming accelerates tallgrass prairie biodiversity.

Byline: Journal Record Staff

NORMAN A University of Oklahoma study on climate warming in an Oklahoma tallgrass prairie has implications for understanding and predicting ecological consequences of climate change and ecosystem management strategies.

"Microbial biodiversity depends on both the size of the area sampled and the time span of the observation," said Jizhong Zhou, director, OU Institute for Environmental Genomics; professor, OU College of Arts and Sciences; and adjunct senior scientist at Lawrence Berkeley National Laboratory.

"Reliable comparison of biodiversity across ecosystems must consider both area and time," Zhou said. "This presents challenges for determining appropriate time scale for biodiversity assessment and conservation in ecosystem management."

Zhou and OU researchers collaborated with researchers from Central South University, Tsinghua University, China and Michigan State University. The study is the first demonstration illustrating that soil microbes exhibit microbial phylogenetic diversity increases with time and document that warming plays predominant roles in regulating temporal scaling.

The research was supported by the U.S. Department of Energy, Office of Science, Genomic Science Program. A paper, "Climate warming accelerates temporal scaling of grassland soil microbial biodiversity," has been published in Nature Ecology & Evolution.
