Distribution of abundance, biomass, production and productivity of macrozoobenthos in the Sub-Antarctic Magellan Province (South America)
Distribution of abundance, biomass, productivity and production of macrozoobenthos was investigated in four study areas in the Magellan region(South Patagonian Ice-Field, Strait of Magellan, Beagle Channel. Continental Shelf). Using a Reineck box corer and a multibox corer, a total of 277 quantitati...
