Reproductive ecology of Lophelia pertusa in Mingulay Reef and the Logachev mounds (North East Atlantic): a multi‐scale comparison
This paper presents the results of a multi-scale comparison in the reproductive stage of the cold-water coral Lophelia pertusa in two areas of the North-east Atlantic: The Mingulay Reef and the Logachev Mounds. The study was carried out during the Research cruise “Changing Oceans” on board of the RR...

The comparison between single colonies and within the same colony from the Mingulay Reef did not show any differences in the maturity stage of the oocytes, nevertheless the analyses of the reproductive stage between mesenteries within the same polyps showed high variability, which indicates that the gametogenic development within each mesentery undergoes a prolonged period of oocyte production.

This paper presents the results of a multi-scale comparison in the reproductive stage of the cold-water coral Lophelia pertusa in two areas of the North-east Atlantic: The Mingulay Reef and the Logachev Mounds. The study was carried out during the Research cruise “Changing Oceans” on board of the RRV James Cook, conducted in May-June 2012. The comparative study between the two geographical areas revealed higher fecundity for the colonies analysed from Mingulay Reef compared to the colonies from the Logachev mounds. Moreover the development stage of the oocytes was more advanced in the colonies sampled from Mingulay than in the ones collected from Logachev. The comparison between single colonies and within the same colony from the Mingulay Reef did not show any differences in the maturity stage of the oocytes, nevertheless the analyses of the reproductive stage between mesenteries within the same polyps showed high variability, which indicates that the gametogenic development within each mesentery undergoes a prolonged period of oocyte production. This probably results in a protracted spawning period, which might improve the reproductive success of the species.
