生态专业化涉及所有物种,是许多主要的生态和进化模式的基础。然而,它作为一个统一概念的地位并不总是被欣赏,因为它与利基概念相似,它适用于生物现象的多个层面,以及影响它的机制的复杂性。专业化的演变要求对适应性进化的约束与基因型和环境表现的协变相结合。这种协变本身取决于生物特性,如扩散行为和生活史,以及由物种相互作用和资源的时空异质性等因素引起的环境复杂性。在这里,我们发展了一种专业化的观点,整合了一系列生物现象,目标是开发一个更具预测性的概念框架,具体说明生物复杂性和共同进化事件的重要性。
Ecological specialisation concerns all species and underlies many major ecological and evolutionary patterns. Yet its status as a unifying concept is not always appreciated because of its similarity to concepts of the niche, the many levels of biological phenomena to which it applies, and the complexity of the mechanisms influencing it. The evolution of specialisation requires the coupling of constraints on adaptive evolution with covariation of genotype and environmental performance. This covariation itself depends upon organismal properties such as dispersal behaviour and life history and complexity in the environment stemming from factors such as species interactions and spatio-temporal heterogeneity in resources. Here, we develop a view on specialisation that integrates across the range of biological phenomena with the goal of developing a more predictive conceptual framework that specifically accounts for the importance of biotic complexity and coevolutionary events.
