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. |
| | | | Loc: | | | Angola, Congo, Morocco-Mauritania, off Madeira, off Coruña, NW Spain, Bay of Biscay (Belon estuary), Scotland, Ireland, Medit. (Algiers, Balearic Sea, G. of Lion (Thau Lagoon), Ligurian Sea, Tyrrhenian Sea, G. of Naples, Taranto, Adriatic Sea, Venise, G. of Manfredonia, Aegean Sea, Thracian Sea, Lebanon Basin, Marmara Sea), | | | | N: | 44 | | | | Lg.: | | | (307) F: 0,95; M: 0,95; (379) F: 0,86-0,74; M: 0,74-0,68; (380) M: 0,76; (449) F: 0,95; (881) F: 0,74-0,95; M: 0,68-0,74; {F: 0,74-0,95; M: 0,68-0,95} | | | | Rem.: | hyperbenthic. Sampling depth: 0-300 m.
A doubt subsists concerning the validity or the synonymy from Diaixis durani; Othman & Greenwood (1994, p.988) the species is considered as valid. | | | Last update : 28/10/2022 | |
