Effects of pelagic larval duration on the geographic population structure of two sipunculan species in the Sea of Japan
This study examines genetic diversity in two species of sipunculan worm, Phascolosoma agassizii and Themiste pyroides, in the Sea of Japan. Low sea levels of the Pleistocene era partially or completely isolated marginal ...
Eurythoe complanata: more cryptic species in the Pacific?
Mitochondrial DNA data has shown that Eurythoe complanata is a cryptic species complex characterized by deeply divergent sympatric populations in the Atlantic, and on either side of Panama, despite almost no morphological ...
Polychaete feeding behavior and geographical distribution in the Gulf of Mexico
Polychaete annelids contribute greatly to macrofaunal species diversity in dynamic deep-sea ecosystems. The aim of our study was to assess the functional composition of deep-sea polychaete assemblages in the Gulf of Mexico. ...
Genotypic diversity of Sabellid worms from carbon dioxide vents
Marine carbon dioxide vents are very common in the Mediterranean Sea, especially around Italy and Greece where they typically eject volcanic fluids containing up to 1-2% hydrogen sulfide. Natural CO2 venting sites have ...
