The sensitivity of insect populations to climate is universally appreciated (Andrewartha and Birch 1954; Lawton 1995). Climate can also synchronize populations of conspecifics over regional scales when dynamics are driven by similar density-dependent processes—the Moran effect (Moran 1953; Ranta et al. 1995, 1997; Royama 1996). However, the possibility that climatic events can also synchronize populations of many species over large geographic scales is less well documented.
Hawkins et al. (Tue,) studied this question.
