Abstract
Hybridization experiments between seven north and south Atlantic Laminaria species were carried out. Morphologically normal F1 sporophytes developed from the following crosses among south Atlantic species: L. pallida x L. schinzii, L. pallida x L. abyssalis and L. schinzii x L. abyssalis. Normal F1 sporophytes also resulted from the crosses L. digitata (north Atlantic) x L. pallida (south Atlantic) and L. digitata (north Atlantic) x L. abyssalis (south Atlantic). Hybrids between north Atlantic L. ochroleuca and south Atlantic L. pallida, L. schinzii and L. abyssalis and between north Atlantic L. digitata and south Atlantic L. schinzii initially developed as normal sporophytes but became deformed later on and further development was retarded. No hybrids resulted from attempted crosses between northeastern Atlantic L. saccharina and L. abyssalis from Brazil. Temperature tolerance, relative growth rates and temperature demands for gametogenesis revealed the existence of a warm temperate group within the digitate Laminaria species consisting of L. ochroleuca, L. pallida, L. schinzii and L. abyssalis. Hybridization experiments and temperature responses suggest that north Atlantic L. digitata and L. ochroleuca are still similar to south Atlantic Laminaria species, confirming the speculation that a transequatorial migration of a warm-temperate L. ochroleuca-like ancestor may have taken place.
