The term allochrony is used to describe the general ecological …
WebApr 7, 2024 · Phenotypic variation, including developmental and behavioral plasticity, had been characterized as proximal causes . Focusing on ultimate causes to the exclusion of proximal ones can be misleading because natural selection can only act on genes if they are 1) expressed, and; 2) result in phenotypic differences that affect survival and reproduction. WebPlastic transgenerational phenotypic variation, a direct result of perceived environmental conditions by previous generations, creates variation on which natural selection can act …
WebAug 18, 2024 · Phenotypic plasticity, the property by which living organisms express different phenotypes depending on environmental conditions, can impact their response to environmental perturbation, including that resulting from global climate change ( Reed et al., 2011; Chevin et al., 2013; Merilä and Hendry, 2014; Sgrò et al., 2016; Bonamour et al., 2024 ).
