El Nino-Southern Oscillation (ENSO) is a meteorological/oceanographic feature which occurs every few years at low latitudes, particularly in the E Pacific from the equator southwards. Consequences include anomalous oceanic warming, reduced upwelling, high rainfall and a decline in fishery yields. The 1982-83 event was particularly severe, spreading its effects more broadly and more deeply in the Pacific than hitherto this century. Coral reefs ceased growing and many became prone to erosion. The marine food base became depleted, with consequential disturbances along the food chain. Reproductive failure was noted in many ocean-feeding birds, and uncharacteristic bird migrations also took place. Terrestrial communities were also affected, eg drought in Panama and rainfall torrents in the Atacama and Peruvian deserts. The 18 contributions (each abstracted separately) examine the physical aspects of ENSO and review a range of environmental and ecological consequences. -P.J.Jarvis
