Phenotypic stasis with genetic divergence

The paper evolves Caenorhabditis elegans populations for 240 generations and finds phenotypic stasis in locomotion behavior despite genetic divergence.

Variation in mutational (co)variances

The paper estimates the M matrix for locomotion traits in two C. elegans genotypes and finds similar mutational variances but differences from a lab-adapted G matrix due to linkage disequilibrium.

Selection and the direction of phenotypic evolution

The paper shows ancestral phenotypic plasticity in C. elegans does not align with genetic variance, but selection can predict the direction of phenotypic divergence.

The evolution of phenotypic plasticity in response to temperature stress

This study shows that thermal plasticity of gene expression evolves in response to temperature stress in Drosophila simulans, with most ancestral plasticity increasing in more extreme environments.

A morphological trait involved in reproductive isolation between Drosophila sister species is sensitive to temperature

The study examines how temperature affects the shape of male genitalia in Drosophila species, finding that D. santomea's ventral branches change shape at lower temperatures, suggesting a link to speciation.

Selection and drift determine phenotypic stasis despite genetic divergence

The paper shows phenotypic stasis in C. elegans despite genetic divergence, due to stabilizing and disruptive selection, with genetic variance-covariance structure changes explained by selection and drift.

From individuals to populations: How intraspecific competition shapes thermal reaction norms

This study examines how intraspecific competition and temperature jointly affect growth rate and asymptotic length in ectotherms, showing competition modulates the temperature-size rule.

Polygenic adaptation fuels genetic redundancy in Drosophila

This study shows that polygenic adaptation in Drosophila simulans leads to genetic redundancy, enabling rapid evolutionary responses through multiple genetic pathways.

A simple genetic basis of adaptation to a novel thermal environment results in complex metabolic rewiring in Drosophila

This study shows that a simple genetic basis for thermal adaptation in Drosophila leads to complex metabolic changes, highlighting the role of large-effect loci in rapid adaptation.
