The relative impact of evolving pleiotropy and mutational correlation on trait divergence

This study models how evolving pleiotropy and mutational correlation affect trait divergence, finding that pleiotropic connectivity evolution is more effective for trait decoupling.

Dissecting the genetic architecture of quantitative traits using genome-wide identity-by-descent sharing

This study estimates quantitative genetic parameters in sticklebacks using IBD sharing, finding that low relatedness variance impairs estimation but half-sib designs allow accurate heritability and additive variance assessment.

Disentangling adaptation from drift in bottlenecked and reintroduced populations of Alpine ibex

This study assesses the ability of selection detection methods to distinguish adaptation from drift in bottlenecked Alpine ibex populations using simulations and empirical data.

A tradeoff between robustness to environmental fluctuations and speed of evolution

This study shows a tradeoff between robustness to environmental fluctuations and speed of evolution in life histories.

Pleiotropy or linkage? Their relative contributions to the genetic correlation of quantitative traits and detection by multi-trait GWA studies

This study compares how pleiotropy and linkage affect genetic correlations between traits and their detection in multi-trait GWAS.

Genetic variance in fitness and its cross-sex covariance predict adaptation during experimental evolution

This study predicts and tests adaptation in red flour beetles under different environmental stresses using genetic variance in fitness and its cross-sex covariance.

Floral signals evolve in a predictable way under artificial and pollinator selection in Brassica rapa using a G-matrix

The paper predicts evolutionary changes in floral traits of Brassica rapa under artificial and pollinator selection using a G-matrix, showing predictable responses and genetic covariance effects.

Purging of highly deleterious mutations through severe bottlenecks in Alpine ibex

The paper shows that severe population bottlenecks in Alpine ibex led to purging of highly deleterious mutations but accumulation of mildly deleterious ones, highlighting the need to prevent population declines below ~1000 individuals.

Restoring ancestral phenotypes by reduction of plasticity is a general pattern in gene expression during adaptation to different stressors in Tribolium castaneum

The paper shows that during adaptation to different stressors in Tribolium castaneum, gene expression shifts toward ancestral levels, with reduced plasticity and increased mean expression.

Combining transcriptomic and fitness data reveals adaptive and mostly additive plastic responses of gene expression to multiple stress in Tribolium castaneum.

The paper combines fitness and transcriptomic data in Tribolium castaneum to show gene expression responses to drought, heat, and their combination, revealing mostly additive effects and adaptive plasticity.

When do shifts in trait dynamics precede population declines?

The paper shows that shifts in fitness-related traits can precede population declines under medium-to-slow environmental change, influenced by predictability, reproductive rate, plasticity, and genetic variation.

Species’ range dynamics affect the evolution of spatial variation in plasticity under environmental change

This study uses individual-based simulations to show how environmental range dynamics influence the evolution of spatial variation in tolerance and plasticity across species ranges under different environmental change scenarios.
