THE MACROBENTHIC ECOLOGY OF THE STRAITS OF MAGELLAN AND THE BEAGLE CHANNEL

The macrobenthic community of the Straits of Magellan and the Beagle Channel was investigated using a Reineck box corer at 22 stations during the Chilean "Cimar Fiordo 3" expedition in 1997. A total of 173 taxa represented by 2188 individuals were identified and are reported for the invest...
