Intertidal seaweeds from North Atlantic Patagonian coasts, Argentina
The coasts located between 39°S and 41°S in the Argentinean biogeographic province have been described by impoverished seaweed assemblages, however the floristic information about this region is sparse. The aim of this study was to survey the intertidal seaweeds inhabiting three sites in the oceanog...
