Differential effects of warming on carbon budget, photosynthetic yield and biochemical composition of cold-temperate and Arctic isolates of Laminaria digitata (Phaeophyceae) Open
Cold-temperate and Arctic hard bottom coastal ecosystems are dominated by kelp forests, which have a high biomass production and provide important ecosystem services, but are subject to change due to ocean warming. However, the photophysio…

Varying photosynthetic quotients strongly influence net kelp primary production and seasonal differences increase under warming Open
Reliable net primary production (NPP) estimations of kelp forests are important to evaluate their C-fixation potential. Photosynthetic oxygen measurements can be converted to C-fixation using photosynthetic quotients (PQs). Although there …

The challenge of estimating kelp production in a turbid marine environment Open
Coastal kelp forests produce substantial marine carbon due to high annual net primary production (NPP) rates, but upscaling of NPP estimates over time and space remains difficult. We investigated the impact of variable underwater photosynt…

Microscopic Stages of North Atlantic Laminaria digitata (Phaeophyceae) Exhibit Trait-Dependent Thermal Adaptation Along Latitudes Open
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…

Looks can be deceiving: contrasting temperature characteristics of two morphologically similar kelp species co-occurring in the Arctic Open
Two morphologically similar digitate kelp species, Laminaria digitata and Hedophyllum nigripes , co-occur along a shallow sublittoral depth gradient in the Arctic but, in contrast to L. digitata , very few ecophysiological data exist for H…
