Roles of the seasonal dynamics of ecosystem components in fluctuating indirect interactions on a rocky shore.

abstract：:Historically, desert drainages of the American southwest supported productive riverine wetlands (ciénegas). Region-wide erosion of ciénegas during the late 19th and early 20th century dramatically reduced the abundance of these ecosystems, but recent reestablishment of wetlands in Sycamore Creek, Arizona, USA, provide...
