Surf zone zooplankton communities from the west coast of the Iberian Peninsula — Influence of season, substrate type and environmental factors

Studies on surf zone zooplankton biodiversity and population dynamics processes remain scarce in comparison to other coastal areas. In this work, we analysed the seasonal (winter/summer) variability of assemblage structure copepod biomass distinct areas with different substrate types (sandy beaches/rocky shores) at west coast Iberian Peninsula (Portugal). Cypris Cirripedia Acartia clausi prevailed during summer both winter, Paracalanus parvus Temora longicornis were most abundant species sandy beaches, while Harpacticoida n.id.1 Euterpina acutifrons dominated rocky shores. Copepod was higher winter beaches. Zooplankton showed community according season type, Harpacticoids cirripeds being main responsible for differences, fish eggs harpacticoids mainly differences among substrates. Surf assemblages influenced by temperature, chlorophyll a local hydrodynamics, which reflects reproduction drift water column.
