摘要
本文是《甲壳动物的生殖量与环境关系》系列论文的第二篇,专述桡足类。它和枝角类一样,是一类小型低等甲壳动物,也是浮游生物群落的一个重要组成部分。种类多、数量大、分布广是它的生态特点。
(1)The fecundity of Copepoda is subject to specific variation and seasonal variation. (2)A positive correlation exists between fecundity and temperature within the range of ±15—±20℃, beyond which, the fecundity tends to decrease. (3)The fecundity increases with increasing amount of food. (4)There is a positive correlation between fecundity and size or age of individuals. (5)Species with egg-sacs appear to possess higher fecundity than those depositing eggs directly in water, showing the parental care of eggs to be more favorable for fecundity.
