摘要
Consumers face numerous risks that can be minimized by incorporating different life-history strategies. How much and when a consumer adds to its energetic reserves or invests in reproduction are key behavioral and physiological 適應s that structure communities. Here we develop a theoretical framework that explicitly accounts for 隨機 fluctuations of an individual consumer's energetic reserves while foraging and reproducing on a landscape with resources that range from uniformly distributed to highly clustered. First, we show that the selection of alternative life histories depends on both the mean and variance of resource availability, where depleted and more 隨機 environments promote investment in each reproductive event at the expense of future fitness as well as more investment per offspring.
