On the spatial and temporal variations of zooplankton in Northeast Atlantic shelf waters
165 p. In the present study we have used zooplankton time-series, for the 1999 ¿ 2013 period, coming from long-term monitoring programs carried out at four sites placed along a latitudinal gradient within the Northeast Atlantic Shelves Province, the Bay of Biscay (two sites with a different trophic...
