 Issued from : C.B. Miller in Biological Oceanography, Blackwell Publishing, 2005. [p.363, Fig. 16.16 (a)]. After Dessier & Donguy, 1987.
Time series of abundance estimates for Clausocalanus spp. (mainly C. minor, C. farrani, C. jobei) species sampled along the Pacific equator from passenger liner on a regular schedule.
Miller underlines that serial abundance for this species from the equator to 0°-2°N shows strong seasonality and dramatic reduction during the 1982-1983 El Niño (with a a sharp reduction of nitrate). A long list of other species also nearly vanished in that event. At least the stocks of hebivorous species rebounded immediately in 1984 (see E. rimana, a predator). |
