Characterizing the Influence of Effective Population Size on the Rate of Adaptation: Gillespie's Darwin Domain

Jeffrey David Jensen

Characterizing the role of effective population size in dictating the rate of adaptive evolution remains a major challenge in evolutionary biology. Depending on the underlying distribution of fitness effects of new mutations, populations of different sizes ...

Does Positive Selection Drive Transcription Factor Binding Site Turnover? A Test with Drosophila Cis-Regulatory Modules

Sebastian Maerkl

Transcription factor binding site(s) (TFBS) gain and loss (i.e., turnover) is a well-documented feature of cis-regulatory module (CRM) evolution, yet little attention has been paid to the evolutionary force(s) driving this turnover process. The predominant ...

Tracking genes of ecological relevance using a genome scan in two independent regional population samples of Arabis alpina

Understanding the genetic basis of adaptation in response to environmental variation is fundamental as adaptation plays a key role in the extension of ecological niches to marginal habitats and in ecological speciation. Based on the assumption that some ge ...

Uptake of Cd(II) and Pb(II) by microalgae in presence of colloidal organic matter from wastewater treatment plant effluents

Vera Slaveykova-Startcheva

The present study addresses the key issue of linking the chemical speciation to the uptake of priority pollutants Cd(II) and Pb(II) in the wastewater treatment plant effluents, with emphasis on the role of the colloidal organic matter (EfOM). Binding of Cd ...

Divergent selection in trailing- versus leading-edge populations of Biscutella laevigata

Stéphane Joost

Background and Aims: Knowledge on how climate-induced range shifts might affect natural selection is crucial to understand the evolution of species range. Methods: Using historical demographic perspectives gathered from regional-scale phylogeography on the ...

Effect of humic acid on Cd(II), Cu(II) and Pb(II) uptake by freshwater algae: kinetic and cell wall speciation considerations

Vera Slaveykova-Startcheva, Cristina Lamelas

The present study examines the effect of humic acid on the uptake kinetics of Cd(II), Cu(II), and Pb(II) by the freshwater alga Chlorella kesslerii. The results demonstrated that the relative proportion of Pb in the cell wall layer is greater than that of ...

Road runoff over the shoulder diffuse infiltration : real-scale experimentation and optimization

Pascal Piguet

A new concept of road runoff management, based on diffuse infiltration over the shoulder, was tested in a real-scale experimentation site located near Grandson, Switzerland. This new concept consists in diffusely infiltrating the road runoff in the infiltr ...
