Distribution map of Acartia (Acartiura) margalefi by geographical zones

| | | | | | | | |  Issued from : M.G. Mazzocchi, L. Dubroca, C. Garcia-Comas, I. Di Capua & M. Ribera d'Alcalà in Progr. Oceanogr., 2012, 97-100. [p.143, Fig.10].
Long-term variability of the abundance (Ind. m3) of rare copepod species that disappeared in the second period of the time-series at Station MC (Gulf of Naples), by vertical tows in the upper 50 m.
Mazzocchi & al. (2012, p.148) point to this species is typically found in harbors and other semi-enclosed systems such as coastal ponds. It was a dominant copepod in the Venice Lagoon until the late 1980s when in the 1990s it was replaced by Acartia tonsa introduced in the mediterranean in the early 1980s. During the same period, A. margalefi has also almost disappeared from the Po River Delta and has drastically reduced its confinement to littoral lakes along the Tyrrhenian coasts. |

This species is dedicated to Ramon Margalef, Professor of Ecology at the University of Barcelona.
My students at the Laboratoire Arago (Laboratory Arago in Banyuls sur Mer that he knew well) studied his works as models of creativity. Fertile spirit, boiling with ideas, playing with physico-ecological concepts, one could characterise him as the "Dali" of Oceanography, other great Catalan personality. Under a serious and severe cover, he had a great sense of humour, defining a copepod as: "a fifth leg attached to something". (see: Hommage to Ramon Margalef in Oecologia aquatica, 10, Publ. Universitat de Barcelona, 1992).
Vives & Shmeleva (2007, p.425) do not admit the synonymy with Acartia lefevrae, contrary to Bradford-Grieve (1999, p.4). Some localisations are debatable in brackish waters (estuaries and harbour installations).
For Sei & Ferrari (2006 a, p.1, 2) the new occurrence of A. tonsa in the Lisa lagoon (S. Adriatc Sea) may have caused the disappearance of the A. margalefi. Like in the Venice's Lagoon after Camatti & al. (2006, p.51-52).
