资源专属性和资源通性的演变引起了广泛的兴趣。影响生态位分化和资源专业化的进化驱动因素集中在权衡的作用上。然而,在这里,我们将探讨如何合作的作用,通过利他行为介导,和经典的资源消费者动态可以影响资源利用的演变。使用进化入侵的方法,我们研究如何关键的阈值水平的利他主义需要资源专业化的出现和维护。互补(必要)和可替代资源之间的差异影响资源通才的演变。资源偏好的强度加上利他主义的水平预计会影响通才的演变。将适当的进化博弈与生态动力学相结合,可以在社会行为与种群动力学之间的反馈中产生新的期望,从而有助于理解经典的生态学问题。
The evolution of resource specialism and generalism has attracted widespread interest. Evolutionary drivers affecting niche differentiation and resource specialization have focused on the role of trade-offs. Here, however, we explore how the role of cooperation, mediated through altruistic behaviors, and classic resource–consumer dynamics can influence the evolution of resource utilization. Using an evolutionary invasion approach, we investigate how critical thresholds in levels of altruism are needed for resource specialization to arise and be maintained. Differences between complementary (essential) and substitutable resources affect the evolution of resource generalists. The strength of resource preferences coupled with the levels of altruism are predicted to influence the evolution of generalism. Coupling appropriate evolutionary game and ecological dynamics lead to novel expectations in the feedbacks between social behaviors and population dynamics for understanding classic ecological problems.
