Phenotypic plasticity facilitates initial colonization of a novel environment

Abstract: Phenotypic plasticity can allow organisms to respond to environmental changes by producing better matching phenotypes without any genetic change. Because of this, plasticity is predicted to be a major mechanism by which a population can survive the initial stage of colonizing a novel environment. We tested this prediction by challenging wild Drosophila melanogaster with increasingly extreme larval environments and then examining expression of alcohol dehydrogenase (ADH) and its relationship to larval survival … Show more

“…Heritable variation for both ADH activity and ADH plasticity were high, with narrow‐sense heritabilities h2=0.557 and h2=0.776, respectively. From these results, Wang and Althoff () concluded that ADH plasticity is an adaptive trait, which is an important finding because adaptive trait plasticity is uncommon (Scheiner ).…”

“…In the former, Drosophila spp. In particular, the capacity for experimental evolution in Drosophila and its abundant genetic and genomic resources, make it a great candidate for studying various phases and the underlying mechanisms (especially the transition from plastic to nonplastic trait production) of PLE as it unfolds (e.g., Debat, Debelle, & Dworkin, 2009;Fanti et al, 2017;Wang & Althoff, 2019). The emphasis on Drosophila is unsurprising, given that they are used to study many evolutionary questions.…”
