Quality of biodiversity, not just quantity, is key
Date:12/6/2013

DURHAM, N.C. -- For years, scientists have believed that preserving more species, no matter which ones, is a key component to enhancing how well an ecosystem performs.

Not so fast, say scientists at Duke University and the University of Massachusetts at Boston.

In a new study of biodiversity loss in a salt marsh, published this week in the Proceedings of the National Academy of Sciences, they find that it's not just the total number of species preserved that matters, it's the number of key species.

If humans want to reap the benefits of the full range of functions that salt marshes and other coastal ecosystems provide, we need to preserve the right mix of species, they said.

"Having a group of distantly related species, representing markedly different ecologies and biology, is as important, or more important, than just having more species in general," said Brian R. Silliman, Rachel Carson associate professor of marine conservation biology at Duke's Nicholas School of the Environment.

"It's quality, not just quantity," said lead author Marc J. S. Hensel, a Ph.D. student at the University of Massachusetts at Boston. "We need to preserve a wide variety of species."

Salt marshes perform a long list of ecological services: they buffer coastal erosion; filter runoff; reduce the risk of flooding; provide habitat for juvenile fish, crabs and shrimp; and store excess carbon, keeping it from re-entering Earth's atmosphere.

To better understand how the loss of key species affects these functions, Silliman and Hensel conducted a tightly controlled eight-month field experiment in a salt marsh on Sapelo Island, Ga. They set up eight different experimental treatments, each with a different mix of three of the marsh's most abundant "consumer" species: purple marsh crabs; marsh periwinkle snails; and fungus. At first, all three species were present, to mirror the natural "intact" conditions of the m
