Ecological divergence is marked by species specific plastic gene expression and distinct rhizosphere among sibling allopolyploid marsh orchids (Dactylorhiza)

This study examines gene expression and root mycobiome diversity in two allopolyploid orchids to understand how plasticity and environmental factors influence their ecological divergence and persistence.

Adaptive, maladaptive, neutral, or absent plasticity: Hidden caveats of reaction norms

The paper shows that reaction norms alone cannot determine if a trait exhibits adaptive, maladaptive, neutral, or no plasticity without knowing the trait's relationship to fitness or local adaptation.

Shallow environmental gradients can cause range margins to form

The paper shows that shallow environmental gradients can lead to sharp range margins when multiple selection gradients steepen each other, even if one gradient is shallow across the range.

The role of phenotypic plasticity in the establishment of range margins

This study investigates how phenotypic plasticity affects population range margins when genetic variance evolves, finding that plasticity can enhance range expansion below a critical cost threshold.

The Heterochromatin protein 1 is a master regulator in RNA splicing precision deficient in ulcerative colitis

This study identifies HP1γ as a regulator of RNA splicing in the gut, showing its deficiency leads to splicing errors and progerin production, linking it to ulcerative colitis and aging diseases.

The effect of genetic architecture and selfing on the capacity of a population to expand its range

This study uses simulations to show that reduced recombination and selfing can enhance range expansion in populations by mitigating genetic drift and deleterious allele accumulation.
