Abstract

Large-scale analyses of the effects of climate change on the Earth's biodiversity miss numerous local processes of crucial importance. This can be illustrated by using the sensitive forests of high-oceanic islands as model ecosystems. The montane rain forest on the island of Hawaii, for instance, was affected by a decline of canopy trees in the 1970s. Here, extreme climatic fluctuations, e.g. during an episodic lifting of the cloud layer in ENSO years, cause abiotic stress, thus functioning as dieback triggers, whereby synchronized senescence of the dominant tree species acts as a major predisposing cause. The extent of rapid oscillation between high precipitation and droughts increased over the last 40 years.
