From October 10, 1979 to August 26, 1981 we investigated the effect of physical disturbance, herbivory and algal-algal competition on the dynamics of the Macrocystis community near Valdivia, Chile.

Marine algae are integral to global biogeochemical cycles, with their capacity for photosynthesis underpinning both primary productivity and climate regulation. The process, which converts light ...

The southern coast of Chile appears to be a safe haven for giant kelp forests (Macrocystis pyrifera). With stalks up to 60 meters long, these algae form underwater forests in coastal waters of the ...

New measurements show that ‘Marine heatwaves’ around an island in Baja California helped invasive algae species to wipe out a native underwater kelp forest, with potentially dramatic effects for the ...

If Earth were to be suddenly devoid of all life, but otherwise unchanged, and I were to drop a single photosynthetic bacterium or alga in the ocean, how long would it take to colonise all the seas?
