Figures

Planche 1 issued from : T.E. Bowman in Smithson. Contr. Zool., 1971, 96. [p.25, Fig.20].
Female (from 33°34'N, 78°24'W): a-b, habitus (lateral and dorsal, respectively); c, 5th pedigerous and genital segments (lateral); d-e-f, last thoracic segment, genital and 2nd urosomal segments (dorsal, right and left sides, respectively); g, anal segment and caudal rami (dorsal); h-k, P1 to P4, respectively; l, P5

Nota: Prosome about 3 times as long as urosome, with characteristic dorsal hump (similar to those in some species of Acrocalanus but less strongly developed). Head and 1st pedigerous somite fused, 4th and 5th separated by indistinct suture. Genital segment rather broad in relation to length; lateral part of posterior margin sometimes armed with row of minute spinules, lateral surface with cluster of spinules on either side, anterior and dorsal to spermatheca. Spermatheca obovate; remaining urosomites relatively broader and shorter than those of P. indicus. A1 25-segmented, reaching to about posterior margin of caudal ramus. Swimming legs pattern very similar to that of P. indicus , basipod conspicuously spinose. P5, terminal spine longer than 2nd segment.

Paracalanus quasimodo density (inds. m3).
Samples collected monthly on days of full moon at Cabo Frio, Brazil (23.8° S, 42.018 °W) from January to December 2011, by horizontal hauls (1 m depth).
The dominance of P. quasimodo was due to its emphasis on herbivory (R2 = 0.83) and lead to a decrease in the planktonic diversity (R2 = 0.63).
The results revealed that predation by carnivorous copepods , like Corycaeus spp. and Oncaea spp, is the main opposing factor affecting P. quasimodo dominance (R2 = 0.70

Remarques

Signalé par erreur en Méditerranée occidentale in Ounissi & Khelifi-Touhami (1999, p.10).
Certaines confusions sont possibles entre cette espèce et P. parvus ou P. indicus.
La présence de cette espèce à San Francisco pourrait avoir été introduite par les ballasts des navires, comme dans les eaux sino-japonaises.
