Cities represent novel environments where altered ecological conditions can generate strong selection pressures leading to the evolution of specific urban phenotypes. Is there evidence for such adaptive changes in urban populations which have colonized their new environments relatively recently? A growing number of studies suggest that rapid adaptations may be widespread in wild urban populations, including increased tolerance to various anthropogenic stressors, and physiological, morphological and behavioural changes in response to the altered resources and predation risk. Some of these adaptive changes are based on genetic differentiation, although other mechanisms, such as phenotypic plasticity and epigenetic effects, are also frequently involved.

Biologia Futura:城市人口的适应性变化

城市代表了新的环境,改变的生态条件可以产生强大的选择压力,导致特定城市表型的演变。是否有证据表明最近在新环境中定居的城市人口发生了这种适应性变化?越来越多的研究表明,快速适应可能在城市野生种群中普遍存在,包括对各种人为压力源的耐受性增加,以及对资源变化和捕食风险的生理、形态和行为变化。这些适应性变化中的一些是基于遗传分化,尽管其他机制,如表型可塑性和表观遗传效应,也经常涉及。
