Magellan Bryozoa: a review of the diversity and of the Subantarctic and Antarctic zoogeographical links

Based principally on previous work by the author, the Magellan Bryozoa are reviewed in terms of endemism, specific diversity, zoarial diversity and polymorphism. The Magellan, Atlantic, Pacific, Subantarctic and Antarctic zoogeographical relationships are reevaluated. New data related to the distrib...

Description
Summary:Based principally on previous work by the author, the Magellan Bryozoa are reviewed in terms of endemism, specific diversity, zoarial diversity and polymorphism. The Magellan, Atlantic, Pacific, Subantarctic and Antarctic zoogeographical relationships are reevaluated. New data related to the distribution of Magellanic and Antarctic species along the archipelagos of the Scotia Arc and new data on Bryozoa from the Magellan continental slope are added. Se revisa la briozoofauna magallánica en términos de endemismo, diversidad específica, diversidad zoarial y de polimorfos. Se reevalúan las relaciones zoogeográficas transpacíficas, transatlánticas, subantárticas y antárticomagallánicas. A la revisión anterior basada en trabajos previos del autor se añaden nuevos datos referentes a la briozoofauna magallánica del talud y a la vicariancia entre especies antárticas y magallánicas. Se evalúa el papel del Arco de Escocia en el movimiento de especies desde y hacia la Antártida.
