林谦 r策略和k策略 | 一个来自生态学的学说,叫做「r/K选择理论(r/K selection theory)」。这个理论说的是生物体如何权衡后代的数量与品质。有些生物体追求后代的数量,称之为「r策略」,r来自英文rate一次,代表增长率。r策略的特点是大量地繁殖后代,一次生几百上千个,但是生下来就不管了,任其自生自灭。像鱼...
Density-dependent genetic evolution was tested in experimental populations of Drosophila melanogaster subject for eight generations to natural selection under high (K-selection) or low (r-selection) population density regimes. The test consisted of determining at high and at low densities the per capita...
r-K 选择（r/K selection theory），是生态学中关于“种群繁殖”的一种研究理论，表示生物对它所处生存条件的不同适应方式。该理论由生态学家麦克阿瑟（MacArthur）和威尔逊（Wilson）提出。其中，K是德语单词Kapazitätsgrenze的首字母缩写，表示环境最大容纳量。r则是表示最大增长率maximum growth rate。这些字母...
