Microscopic life stages of North Atlantic Laminaria digitata (Phaeophyceae) exhibit trait-depedent thermal adaptation along latitudes
Kelp forests in the North Atlantic are at risk of decline at their warm temperature distribution margins due to anthropogenic temperature rise and more frequent marine heat waves. To investigate the thermal adaptation of the cold-temperate kelp Laminaria digitata, we sampled six populations, from th...
