The ability to adapt to marginal habitats, in which survival and reproduction are initially poor, plays a crucial role in the evolution of ecological niches and species ranges. Adaptation to marginal habitats may be limited by genetic, developmental, and functional constraints, but also by consequences of demographic characteristics of marginal populations. Marginal populations are often sparse, fragmented, prone to local extinctions, oil are demographic sinks subject to high immigration from high-quality core habitats. This makes them demographically and genetically dependent Oil core habitats and prone to gene flow counteracting local selection. Theoretical and empirical research in the past decade has advanced Our understanding of conditions that favor adaptation to marginal habitats despite those limitations. This review is an attempt at synthesis of those developments and of the emerging conceptual framework.
