Broad scale factors influencing the biodiversity of coastal benthic communities of the Ross Sea
none 10 Early ecological research in McMurdo Sound revealed local spatial gradients in community structure associated with variations in anchor ice disturbance, fast ice and snow cover, and the effects of predators. Research contrasting the east and west sides of McMurdo Sound has shown major differ...
