Adaptive maternal effects and rapid population differentiation

نویسنده

چکیده

How rapidly can two populations diverge when exposed to different selection pressures? And what mechanisms contribute to rapid population divergence? A remarkable new study by Badyaev et al. of house finches Carpodacus mexicanus suggests that simultaneous maternal adjustment of offspring sex ratio and growth rates has played an important role in rapid population differentiation associated with an explosive range expansion.

An explicit test for the contribution of environmental maternal effects to rapid clinal differentiation in an invasive plant.

Population differentiation of alien invasive plants within their non-native range has received increasingly more attention. Common gardens are typically used to assess the levels of genotypic differentiation among populations.However, in such experiments, environmental maternal effects can influence phenotypic variation among individuals if seed sources are collected from field populations unde...

Population divergence in compensatory growth responses and their costs in sticklebacks

Compensatory growth (CG) may be an adaptive mechanism that helps to restore an organisms' growth trajectory and adult size from deviations caused by early life resource limitation. Yet, few studies have investigated the genetic basis of CG potential and existence of genetically based population differentiation in CG potential. We studied population differentiation, genetic basis, and costs of C...

Maternal effects and evolution at ecological time-scales

1. Genetic and environmental maternal effects can play an important role in the evolutionary dynamics of a population: they may have a substantial impact on the rate and direction of genetic change in response to selection, and they may generate immediate phenotypic change via phenotypic plasticity. Because of this potential to generate rapid phenotypic change in a population, maternal effects ...

Maternal inheritance and rapid evolution of sexual size dimorphism: passive effects or active strategies?

Adaptive evolution is often strongly influenced by maternal inheritance that transfers the parental strategies across generations. The consequences of maternal effects for the offspring generation depend on the between-generation similarity in environments and on the evolved sensitivity of the offspring's ontogeny to maternal effects. When these factors differ between sons and daughters, matern...

Effects of BIO on proliferation and chondrogenic differentiation of mouse marrow-derived mesenchymal stem cells

In vitro expansion of mesenchymal stem cell (MSCs) into large number is necessary for their application in cell-based treatment of articular cartilage defects. On the other hand, some studies have indicated that BIO (6-Bromoindirubin-3-Oxime) possesses mitogenic effects on cell culture. The objective of the present study was to examine the effect of BIO on in vitro expansion and chondrogenic di...
