Hypoxic conditions and the resultant death or morbidity of macrofauna may benefit scavenging species such as Asterias rubens and Carcinus maenas. However, as oxygen levels drop, they too are excluded. Remineralisation of organic matter in the sediment, and of sulphur by Beggiatoa sp. are probably important processes in nutrient cycling with isolated habitats. In habitats in which the sediment is isolated from surface waters by reduced water flow or mixing (e.g. due to a thermocline), restoration of water mixing probably releases inorganic nutrients to the wider ecosystem.
