Copepod carcasses as microbial hot spots for pelagic denitrification
Description: Copepods are exposed to a high non-predatory mortality and their decomposing carcasses act as microniches with intensified microbial activity. Sinking carcasses could thereby represent anoxic microenvironment sustaining anaerobic microbial pathways in otherwise oxic water columns. Using non-invasive O2 imaging, scientists document that carcasses of Calanus finmarchicus had an anoxic interior even at fully air-saturated ambient O2 level. [Source: Limnology and Oceanography]
