Oxygen depletion can lead to the collapse of benthic ecosystems, i.e. to dead zones, and large-scale biodiversity loss. Based on mortality and survival, we evaluated ranges of sensitivity and tolerance to hypoxia levels, duration of anoxia and H2S exposure across taxa and key life habits. Experiments were conducted on a sublittoral soft-bottom under realistic in situ conditions in a community setting featuring both a well-developed epi- and infauna. Overall, 495 individuals representing 40 species were examined over almost 1000 h (using time-lapse camera and sensor arrays). Mortality started at dissolved oxygen (DO) concentrations
