Many marine species, including mussels in the Mytilus edulis species group (i.e. M. edulis L., M. galloprovincialis Lamarck, and M. trossulus Gould), have an antitropical distribution pattern, with closely related taxa occurring in high latitudes of the northern and southern hemispheres but being absent from the tropics. We tested four hypotheses to explain the timing and route of transequatori...

--USING the trends of equatorial, marginal fracture ridgcs, Le Pichon and Hayes1 proposed an early phase for the opening of the South Atlantic, with a pole of rotation at 21.5-N, 14'W with respect to Africa. Francheteau and Le Pichon2 tested this plate tectonic model with the whole South Atlantic and assunied that there is a relationship between continental niargin offscts, the subsidence of co...

Abstract Northern sand lance (Ammodytes dubius) are essential forage fish in most offshore, temperate-to-polar waters on the Northwest Atlantic shelf (NWA), but their population structure and genetic separation from American (A. americanus) remain unresolved. We assembled a reference genome for A. dubius (first Ammodytidae) then used low-coverage whole sequencing 262 specimens collected across ...

As a contribution to the OCEANOBS99 objectives, we give a brief description of the present knowledge of the South Atlantic and identify some key processes and areas which need to be monitored in order to understand the role of that part of the ocean in the global climate. Included are suggestions of strategies for a first approximation towards an ocean climate monitoring system in the South Atl...

From data on allozyme, nuclear DNA and mitochondrial DNA markers, we show that the originally North Pacific/Northwest Atlantic mussel Mytilus trossulus is widespread on North European coasts, earliM. trossuluser thought to be inhabited only by Mytilus edulis. Several local occurrences of , interspersed with a dominant M. edulis, were recorded on the North Sea, Norwegian Sea and Barents Sea coas...

Energetic, large-scale variability is observed in the atmosphere and ocean of the Atlantic Sector on interannual and decadal time scales. It is manifested as coherent fluctuations in temperature , rainfall, surface pressure and temperature reaching eastward to central Europe and northern Asia, southward to subtropical West Africa and westward to North and South America with a myriad of well doc...
