Preliminary results of the study on the genetic structure of deep populations (below 50m deep) of red sea fan (Paramuricea clavata) found at the underwater canyons of Arenys, Blanes and Palamós (Spain), show that they are very isolated. Even when comparing populations of the same canyon. Also when related to the closest populations of shallower waters of Llafranc and Begur (Spain), continue to be very isolated.
This low capacity of dispersion and its longevity indicate a high fragility, in the sense of low capacity to regenerate after events of massive mortality. This fact has strong implications in conservation policies since these populations are acting as reservoirs of long living organisms and of biodiversity.
These results have been presented at the XVIII Simposio Ibérico de Estudios de Biología Marina, 2-5 September 2014, Gijón (Spain). More information >>
