Sensitivity to Natural Events


Following Holt et al. (1995), McLeod (1996) and Hiscock (in prep) both sensitivity (the likelihood that an organism or community will suffer damage or death when exposed to an external factor) and vulnerability (the likelihood of exposure to an external factor) have been taken into consideration under the general heading of ‘sensitivity’ here.

Some repetition between this chapter and chapter IV (biological and ecological functioning) is unavoidable, though this has been minimised as far as possible. In the main, only instances where ecological events or conditions seem likely to have important effects on biogenic reefs are considered here.
