The Biogeographic Importance of Buoyancy in Macroalgae: A Case Study of the Southern Bull‐Kelp Genus Durvillaea (Phaeophyceae), Including Descriptions of Two New Species 1
Long‐distance dispersal plays a key role in evolution, facilitating allopatric divergence, range expansions, and species movement in response to environmental change. Even species that seem poorly suited to dispersal can sometimes travel long distances, for example via hitchhiking with other, more i...
