Temperature mediates the outcome of species interactions in early life-history stages of two sympatric kelp species
Ocean warming can mediate species interactions and provoke changes in community structure worldwide. Species interactions vary along environmental gradients and life-history stages and increasing temperatures may change competitive dominance between species. Kelps, being marine foundation species, h...

Ocean warming can mediate species interactions and provoke changes in community structure worldwide. Species interactions vary along environmental gradients and life-history stages and increasing temperatures may change competitive dominance between species. Kelps, being marine foundation species, have a complex heteromorphic life cycle, with the early developmental stages being a bottleneck for successful establishment of the adult population. Here, we investigated how temperature influences interactions in early life-history stages of two kelp species with different thermal affinities (Alaria esculenta and Laminaria digitata from Spitsbergen) by cultivating them in mono- and co-culture and different temperatures. Irrespectively of cultivation treatment, spore germination, gametogenesis, and sporophyte development of both species were mostly positively stimulated by a temperature increase from mean ambient summer temperatures (4–5 °C) to a global warming scenario for the Arctic future (9–10 °C) but not at 15 °C which is the southern temperature limit of A. esculenta. At 15 °C gametogenesis and sporophyte formation of A. esculenta were greatly inhibited in monoculture but not so in L. digitata.
