Zooplankton communities in the Drake Passage through environmental boundaries: a snapshot of 2010, early spring
Background Spatial distribution of zooplankton communities influenced by various environmental factors is always important for understanding pelagic ecosystems. The area of the Drake Passage (Southern Ocean) is of particular interest owing to the high spatial and temporal variability of hydrological...
