A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA
Abstract: We present a quantitative food web of the Ross Sea as a step towards investigating ... ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model consolidates ... quantitative information on trophic links across all the major biota of the Ross Sea and tests for data ... consistency. The model has 38 trophic groups and is balanced in terms of annual flows of organic carbon in an ...
