Recurrent hybridization and gene flow shaped Norway and Siberian spruce evolutionary history over multiple glacial cycles

This study examines the evolutionary history of Norway and Siberian spruce, revealing recurrent hybridization and gene flow across glacial cycles, with distinct genetic clusters and refugia shaping their distribution.

Global and local adaptation to aridity in a desert plant Gymnocarpos przewalskii

This study identifies genes involved in global and local adaptation to aridity in Gymnocarpos przewalskii, finding limited overlap between the two processes.

Dominance between self-incompatibility alleles determines the mating system of Capsella allopolyploids

This study shows that dominance between self-incompatibility alleles determines the mating system of allopolyploid Capsella species.

Hybridization mediated range expansion and climate change resilience in two keystone tree species of boreal forest

The paper assesses local adaptation and climate resilience in two conifer species using genetic and ecological data, finding hybridization expands niche breadth and identifies vulnerable populations.

Resilience of genetic diversity in forest trees over the Quaternary

The paper uses population genomic analyses to show that forest trees maintained genetic diversity despite Pleistocene climate changes.

Teasing apart the joint effect of demography and natural selection in the birth of a contact zone

The paper uses genomic data to show that natural selection and demographic history jointly shaped the genetic structure and contact zones in Norway spruce during post-glacial recolonization.

Genome-wide evolutionary response of European oakssince the Little Ice Age

This study tracks genomic changes in European oaks since the Little Ice Age, finding shifts in selection linked to climate extremes and stress responses.

Phenotypic plasticity, population structure and adaptation in a young weed species with a worldwide distribution

This study investigates the roles of phenotypic plasticity and genetic adaptation in the rapid global spread of the weed Capsella bursa-pastoris through common garden experiments.

The selfing syndrome overshadows other differences when comparing fitness across Capsella species

The study compares fitness traits across four Capsella species, finding that outcrossing species outperform selfing ones, while polyploidy and geographic origin have less significant effects.

An introgressed gene causes meiotic drive in Neurospora sitophila

This study identifies a gene responsible for meiotic drive in Neurospora sitophila and shows it was introgressed from a related species.

From drift to draft: How much do beneficial mutations actually contribute to predictions of Ohta’s slightly deleterious model of molecular evolution?

The paper tests the Nearly Neutral Theory by analyzing genomic data from 59 species, finding that both effective population size and beneficial mutations influence the proportion of effectively neutral mutations.

Ecological strategy and genetic load in the shepherd's purse (Capsella bursa-pastoris) from the core and the limit of its natural range.

This study examines how genetic load and ecological strategies affect the performance of shepherd's purse accessions from the front and core of its range under competition.

Genomic data provides new insights on the demographic history and the extent of recent material transfers in Norway spruce

The paper uses genomic data to infer the demographic history of Norway spruce and quantify recent material transfers in a Swedish breeding program.

Assessing the potential for assisted gene flow using past introduction of Norway spruce in Southern Sweden: Local adaptation and genetic basis of quantitative traits in trees.

The paper analyzes the genetic basis of local adaptation in Norway spruce using mixed-origin trees and phenotypic data to assess the potential of assisted gene flow for climate change adaptation.

Towards the new normal: Transcriptomic and genomic changes in the two subgenomes of a 100,000 years old allopolyploid, Capsella bursa-pastoris

This study examines transcriptomic and genomic changes in the subgenomes of an ancient allopolyploid plant, finding strong parental legacy and adaptive expression biases in different tissues.

Variation in competitive ability with mating system, ploidy and range expansion in four Capsella species

The paper compares competitive ability across four Capsella species with different mating systems and ploidy levels, finding selfing species are more sensitive to competition than outcrossers, with ploidy and range expansion influencing this sensitivity.
