Fitness consequences of maternal and grandmaternal effects
Transgenerational effects are broader than only parental relationships. Despite mounting evidence that multigenerational effects alter phenotypic and life-history traits, our understanding of how they combine to determine fitness is not well developed because of the added complexity necessary to study them. Here, we derive a quantitative genetic model of adaptation to an extraordinary new envir...
متن کاملThe benefits of maternal effects in novel and in stable environments.
Natural selection favours phenotypes that match prevailing ecological conditions. A rapid process of adaptation is therefore required in changing environments. Maternal effects can facilitate such responses, but it is currently poorly understood under which circumstances maternal effects may accelerate or slow down the rate of phenotypic evolution. Here, we use a quantitative genetic model, inc...
متن کاملAdaptation to Temporally Fluctuating Environments by the Evolution of Maternal Effects.
All organisms live in temporally fluctuating environments. Theory predicts that the evolution of deterministic maternal effects (i.e., anticipatory maternal effects or transgenerational phenotypic plasticity) underlies adaptation to environments that fluctuate in a predictably alternating fashion over maternal-offspring generations. In contrast, randomizing maternal effects (i.e., diversifying ...
متن کاملThe effect of food type on phenotypic plasticity of sword tail, Xiphophurus helleri, during early ontogeny
Phenotypic plasticity is an important mechanism of phenotypic adaptation in response to environmental conditions. This study was conducted to investigate the effect of food type on the body shape of swordtail, Xiphoohurus helleri, during early development using geometric morphometric method. For this purpose, two treatments including feed by Artemia naupli and commercial Biomar diet were used i...
متن کاملPhenotypic Plasticity and Selection: Nonexclusive Mechanisms of Adaptation
Selection and plasticity are two mechanisms that allow the adaptation of a population to a changing environment. Interaction between these nonexclusive mechanisms must be considered if we are to understand population survival. This review discusses the ways in which plasticity and selection can interact, based on a review of the literature on selection and phenotypic plasticity in the evolution...
