Carte de distribution de Acartia (Acartiura) margalefi par zones géographiques

| | | | | | | | |  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. |

Cette espèce est dédiée à Ramon Margalef, Professeur d'Ecologie à l'Université de Barcelone.
En tant qu'enseignant au Laboratoire Arago (Banyuls), qu'il connaissait bien, j'évoquais aux étudiants ses ouvrages comme des modèles de créativité. Esprit fertile, bouillonnant d'idées, jouant avec les concepts physico-écologiques, on pouvait le caractériser comme le "Dali" de l'océanologie, autre grande personnalité catalane. Sous des dehors sérieux, voire austères, il ne manquait pas de sens de l'humour, me définissant ce qu'était un copépode: une patte 5 attachée à quelque chose. (cf. Hommage to Ramon Margalef inOecologia aquatica, 10, Publ. Universitat de Barcelona, 1992).
Vives & Shmeleva (2007, p.425) considèrent que Acartia lefevrae n'est pas un synonyme de cette espèce. D'où certaines localisations discutables dans les eaux saumâtres des estuaires et portuaires.
