图2 消费者-资源相互作用(改绘自McCann, 2010)。其中R和C分别表示资源和消费者种群密度, r为资源内禀增长率, K为承载力, a为攻击率, R0是资源的半饱和密度, e是转化为消费者生物量的比例, m为消费者的个体死亡率。

Fig. 2 Consumer-resource interaction (redrawing from McCann, 2010). Where R and C are population density of the resource and consumer, respectively, r is intrinsic growth rate of resource, K is the carrying capacity, a is the attack rate, R0 is the semi-saturation density of resource, e is the proportion converted to the consumer biomass, and m is mortality rate of consumer.
