Cell death and degeneration in the symbiotic dinoflagellates of the coral Stylophora pistillata during bleaching [PDF]

open access: yes, 2004
Rising sea temperatures are increasing the incidences of mass coral bleaching (the dissociation of the coral–algal symbiosis) and coral mortality. In this study, the effects of bleaching (induced by elevated light and temperature) on the condition of ...
