摘要
How can so many 物種 coexist in natural ecosystems remains a fundamental question in 生態學. Classical models suggest that competition for space and resources should maintain the number of coexisting 物種 far below the staggering 多樣性 commonly found in nature. To overcome this paradox, theoretical studies have long highlighted a number of mechanisms that can favour 物種 coexistence, from the distribution of interaction strengths between 物種 to the shape of 族群 growth functions. In particular, a family of 數學 models finds that, when sublinear 族群 growth (SG) rates are coupled with competition between 物種, 物種 多樣性 can stabilize community dynamics. This could suggest that SG may explain the stable coexistence of many 物種 in natural ecosystems. Here we clarify why SG models do not solve the paradox of 物種 coexi
