Long-term ecological research has revealed the impact of climate on marine ecosystems at multiple time scales. Changes in pelagic system have been detected LTER-MC site Gulf Naples (Tyrrhenian Sea, western Mediterranean) since 1984. Here we analyzed series to determine whether zooplankton had significantly changed over three decades 1984–2015. In addition seasonal cycle as main mode temporal va...

Understanding the impact of climate change on zooplankton populations is of major importance, as they represent the basis for higher trophic levels in the marine food web. In this study we analyze the 36-year copepod abundance time series in the Gulf of Trieste, northern Adriatic, to investigate its interannual variability, with particular attention to species trends and phenology. Following th...

In the Northern Adriatic Sea, extracellular enzymatic activity was measured during a Lagrangian study following a drifting buoy for 40 h. Dissolved free enzymatic activity represented 20 to 70% of total activity depending on the type of enzyme. aand P-glucosidases exhibited a significantly higher free activity than proteolytic enzymes. In subsequent laboratory experiments we investigated the ef...

Abstract A total of five mesozooplankton time series data sets were assembled to compare the seasonal and interannual patterns abundance calanoid copepods in Western English Channel (Station L4), Celtic Sea, Bay Biscay (Continuous Plankton Recorder), Cantabrian Sea (RADIALES series, Santander, St-4 St-6) from January 1992 December 1999. strong component taxonomic composition was detected at loc...

A new species (Acartia hongi) of Acartia (family Acartiidae) predominating in the Korean coastal waters of the Yellow Sea is described. This species closely resembles Acartia bifilosa, from which it can be easily distinguished by the co-occurrence of the following morphological characters: the absence of rostral filaments in both genders; the terminal spine on the female fifth leg toothed only ...
