互惠是个体之间的种间相互作用,其中每个参与者都从协会中获得净利益(Thompson,1994)。互利共生的概念是广泛的,包括各种各样的非对抗性和非竞争性的种间相互作用。一般来说,这些相互作用涉及商品或服务的交换(例如营养、保护、配子或后代的传播)。根据定义,合作伙伴提供的货物或服务的成本应低于其从协会获得的利益。因此,要证明一个联合体是互利的,就必须证明每个伙伴的适应性相对增加。
Mutualisms are interspecific interactions between individuals in which each participant receives a net benefit from the association (Thompson, 1994). The concept of mutualism is broad encompassing a wide variety of non-antagonistic and non-commensal interspecific interactions. Generally, these interactions involve and exchange of goods or services (e.g. nutrition, protection, dispersal of gametes or progeny). By definition the goods or services provided by a partner should be of low cost relative to the benefits it receives from the association. Therefore, to demonstrate that an association is mutualistic it is necessary to show a relative increase in the fitness of each partner.
