A temporal approach to linking aboveground and belowground ecology

Ecologists are becoming increasingly aware of the role of aboveground-belowground relationships in controlling ecosystem processes and properties. Here, we review recent studies that show that relationships between aboveground and belowground communities operate over a hierarchy of temporal scales, ranging from days to seasons, to millennia, with differing consequences for ecosystem structure and function. We propose that a temporal framework is crucial to our understanding of the nature and ecological significance of relationships between aboveground and belowground communities. © 2005 Elsevier Ltd.
