"In the natural world, species have evolved to be finely attuned to the seasons--timing is everything," said lead author Elsa Cleland, who performed this research as part of her doctoral dissertation at Stanford and is now a postdoctoral fellow at the National Center for Ecological Analysis and Synthesis in Santa Barbara, Calif. "If climate change alters the timing of plant activity, then it could have a domino effect, impacting the feeding, breeding or migration patterns of the animals that rely on particular plant species."
Cleland's co-authors include Nona R. Chiariello, research coordinator of the Jasper Ridge Biological Preserve; Scott Loarie, who assisted with this research while a Stanford undergraduate; Christopher B. Field, director of the Carnegie Institution's Department of Global Ecology (located on the Stanford campus) and faculty director of Jasper Ridge Biological Preserve, and Harold A. Mooney, the Paul S. Achilles Professor of Environmental Biology at Stanford.
The findings are part of the ongoing Jasper Ridge Global Change Experiment, launched in 1998 and designed to demonstrate how a typical California grassland ecosystem may respond to future global environmental changes. Researchers from Stanford and the Carnegie Institution's Department of Global Ecology conducted the experiment in about two fenced-off acres of the 1,189-acre Jasper Ridge Biological Preserve. The experiment was designed to simu
