Document Summary

Recovery after disturbance: controlled by many factors, successional processes are critically important; larger disturbances have longer recovery times, environmental damage is not irreversible, restoration efforts may help, scientific knowledge is critical. Conservation biology: classic case: seahorses, harvested for traditional chinese medicine, aquaria, little knowledge of seahorse ecology: distribution, abundance, taxonomy, fishery pressure, etc, habitat loss is a factor, many species are considered endangered. Coral conservation: protect nearby reefs to promote healthy recruitment to reefs. Increasing evidence that chemical cues are critical to habitat selection by coral reef fishes, coral larvae (dixson 2014: orga(cid:374)is(cid:373)s (cid:272)a(cid:374) (cid:862)s(cid:373)ell(cid:863) a healthy reef, paradox: need a healthy reef to promote other healthy reefs.
