Abstract
Adult E. pacifica obtain a maximum C-specific ration of 8.8% d-1 [day-1] from the centric diatom Thalassiosira angstii and 0.45 % d-1 from the copepod Pseudocalanus sp. E. pacifica exhibits a sigmoidal or stabilizing functional response to diatoms but not to copepods. Adult copepods may be attacked and injured by E. pacifica but they are suboptimal prey item for this omnivore.This publication has 17 references indexed in Scilit:
