..., Paine and Trimble describe a dramatic assemblage shift
on a rocky intertidal shore in Washington State (USA). The change was initiated during the extreme 1997/98 El Nio and has involved replacement of the original algal dominated assemblage by a mussel bed. Starfish are capable of controlling the distri...
Study examines future of species extinction, conservation
