Selection history and epistatic interactions impact dynamics of adaptation to novel environmental stresses

Selection history and epistatic interactions impact dynamics of adaptation to novel environmental stresses.

In rapidly changing environments, selection history may impact the dynamics of adaptation. Mutations selected in one environment may result in pleiotropic fitness trade-offs in subsequent novel environments, slowing the rates of adaptation. Epistatic interactions between mutations selected in sequential stressful environments may slow or accelerate subsequent rates of adaptation, depending on t...

Evolutionary dynamics, epistatic interactions, and biological information.

We investigate a definition of biological information that connects population genetics with the tools of information theory by focusing on the distribution of genotypes found in a population. Previous research has treated loci as non-interacting by making specific approximations in the calculation of information-theoretic quantities. We expand earlier mathematical forms to include epistasis, o...

the present study is a survey os postmodern historical novel with respect to the voice of women. it argues how the recorded history is regulated by the rules of power and how women have been excluded from this discourse.ther study analysez angela carters nights at the circus as an example of postmodern historical novel to illustrate how this novel has questioned the historical narrative and how it has inserted women into history by breaking the rules of patriarchy.
