Distribution map of Subeucalanus crassus by geographical zones

| | | | | | | | | | | |  Issued from : E. Goetze & M.D. Ohman in Deep-Sea Res. II, 2010, 57. [p.2117, Fig.5].
Biogeographic distribution records for Subeucalanus crassus (Atl) and Subeucalanus crassus (Pac), two distinct genetic lineages within the nominal species Subeucalanus crassus s.l. .
Subeucalanus crassus was decribed by Fleminger (1973) as a subtropical-tropical, circumglobal species in eutrophic or broadly neritic waters.
Current sampling of new genetic lineages is inadequate the geographic distribution of these distinct taxa.
Solid and open circles mark sampling locations of specimens whose species identity was verified to be S. crassus (Atl) or S. crassus (Pac), respectively, by DNA sequencing of 165 rRNA.
Note: The 'positive" records plotted from Lang (1965) are a subset of her original material. |
 Issued from : A.J. Southward, S.J. Hawkins & M.T. Burrows in J. therm. Biol., 1995, 20 (1/2). [p.140, Fig.9].Changes in geographical distribution of the warm water copepod Eucalanus (= Subeucalanus) crassus (C & D).
Contours at 1, 10 and 100 individuals per 750 m3.
Nota: The figure gives an example of a latitudinal retreat of one of the warm water species between 1969 and 1979, by comparison with a cold water species as the trachymedusan Aglantha digitalis during the same period, both based on extensive sampling over the entrance of the English Channel and approaches (A. Southward, unpublish. data). The warm water species had retreated south and the cold water plankton had moved into the northern side of the western Channel to replace it. |

Bradford-Grieve (1994, p.88) observes the body of the Southwest Pacific specimens were covered with very small spinules although Farran (1929) noted that his specimen had a smooth integument.
For Goetze & Ohman (2010, p.2117) E. oculanus Marukawa, 1921 in Japanese waters may correspond to Subeucalanus sp. Goetze & Ohman, and not synonym of S. crassus.
