一.r-选择与K-选择每种生物都有其生态对策(bionomicstrategies,ecological strategies).生态对策就反映在大小、世代时间、寿命、生殖能力、分布范围及迁移习性等方面,它能使生物最大限度地适应与利用环境.生物的栖息生境(habitat)可以看成是一块模板,进化动力就在这模板上塑造生物的生态对策(Sou-thwood,1976).
I. Selection and K-selection Each species has its own ecological strategy (bionomic strategies, ecological strategies). Ecological measures are reflected in size, generational time, longevity, reproductive capacity, distribution range, and migration habits, Creatures adapt and use the environment to the maximum extent. Habitat for living things can be considered as a template on which evolutionary forces shape the ecological response of the organism (Sou-thwood, 1976).
