Plant phenotypic plasticity in a changing climate.
Climate change is altering the availability of resources and the conditions that are crucial to plant performance. One way plants will respond to these changes is through environmentally induced shifts in phenotype (phenotypic plasticity). Understanding plastic responses is crucial for predicting and managing the effects of climate change on native species as well as crop plants. Here, we provi...
متن کاملPhenotypic plasticity in evolutionary rescue experiments.
Population persistence in a new and stressful environment can be influenced by the plastic phenotypic responses of individuals to this environment, and by the genetic evolution of plasticity itself. This process has recently been investigated theoretically, but testing the quantitative predictions in the wild is challenging because (i) there are usually not enough population replicates to deal ...
متن کاملPhenotypic plasticity and evolution by genetic
Introduction Why revisit a 50 year old debate? Genetic assimilation is a process whereby environmentally induced phenotypic variation becomes constitutively produced (i.e. no longer requires the environmental signal for expression). Although the origins of this concept can be traced [genetic assimilation] is an interesting but, I would judge, relatively minor outcome of the [synthetic] theory' ...
متن کاملPhenotypic plasticity and evolution by genetic assimilation.
In addition to considerable debate in the recent evolutionary literature about the limits of the Modern Synthesis of the 1930s and 1940s, there has also been theoretical and empirical interest in a variety of new and not so new concepts such as phenotypic plasticity, genetic assimilation and phenotypic accommodation. Here we consider examples of the arguments and counter-arguments that have sha...
متن کاملEnvironmental change, phenotypic plasticity, and genetic compensation.
When a species encounters novel environmental conditions, some phenotypic characters may develop differently than in the ancestral environment. Most environmental perturbations of development are likely to reduce fitness, and thus selection would usually be expected to favor genetic changes that restore the ancestral phenotype. I propose the term "genetic compensation" to refer to this form of ...
