我们认为生态进化过程，包括适应性性状分布的自然界。我们实施生态公理，即人口增长，如果它是充满资源，并没有增长，如果它没有。这些公理产生的自然界的性状的手段，这表明，假设的伽马分布性状，性状方差是一个功能的性状的意思，是更合适的比通常的假设的正态分布性状，性状方差是独立的性状的意思。我们使用一个Lotka-Volterra模型来模拟两个植物种群，其特征意味着根据一个进化模型进化，以模拟种群在入侵过程中的适应。我们的模型模拟使用伽马分布特征的结果表明，适应人口可能会通过增加他们的健身和恢复从濒临灭绝稳定共存的瓶颈。将生态进化过程纳入生态系统模型产生了K-理论，该理论预测了种群的长期状态，使其通过进化瓶颈。否则，不能通过瓶颈的种群的最终状态可以由非进化的R ∞理论预测。
We consider eco-evolutionary processes that include natural bounds on adaptive trait distributions. We implement ecological axioms, that a population grows if it is replete with resources, and doesn’t grow if it has none. These axioms produce natural bounds on the trait means that suggest that the assumption of gamma-distributed traits, where the trait variance is a function of the trait mean, is more appropriate than the usual assumption of normally distributed traits, where the trait variance is independent of the trait mean. We use a Lotka-Volterra model to simulate two plant populations, whose trait means evolve according to an evolutionary model, to simulate populations adapting during invasions. The results of our model simulations using gamma-distributed traits suggest that adapting populations may endure bottlenecks by increasing their fitness and recovering from near extinction to stably coexist. The inclusion of eco-evolutionary processes into ecosystem models generates K∗ theory which predicts the long-term states of populations that make it through evolutionary bottlenecks. Otherwise, the final states of populations that do not make it through bottlenecks may be predicted by the non-evolutionary R∗ theory.
