摘要：

Prosome length of the resting stages of Neocalanus plumchrus and Neocalanus flemingeri varied significantly, but modestly, among years at Station P in the Gulf of Alaska. The range of variation over 20 yr was small relative to the known geographic variation. Among-year length variations were significantly greater than within-year variations, implying similarity of year-to-year variation in growth conditions over an indeterminate, subregional scale. The two species tended to vary in the same fashion both among and within years, despite the offset of about 1 mo in their developmental schedules. Length of N. plumchrus was negatively correlated with Emerson's (1987. J. Geophys. Res. (Oceans) 92(C6): 6535-6544) estimates of May-August new production at Station P from 1969 to 1978.
