Juvenile morphology of the large Antarctic canopy-forming brown alga, Desmarestia menziesii J. Agardh
Abstract For many types of seaweeds in Polar Regions, open questions remain about how their life cycle contributes to their overall adaptation to the extreme abiotic environment. This applies in particular to the major canopy-forming brown algae in much of the Antarctic Peninsula of the genus Desmar...
