bifrost: an R package for scalable inference of phylogenetic shifts in multivariate evolutionary dynamics

The paper introduces bifrost, an R package for detecting shifts in multivariate trait evolution across phylogenetic trees, using a greedy search and information-criterion weights.

The roles of divergent and parallel selection in Amazonian and Andean bird responses to glacial cycles

This study compares divergent and parallel selection in Amazonian and Andean bird species, finding that parallel selection drove faster evolutionary change during glacial cycles.

Climate change introduces threatened killer whale populations and conservation challenges to the Arctic

The paper identifies two genetically distinct killer whale populations in the Arctic, highlights their vulnerability, and discusses conservation challenges due to climate change and human activities.

Unraveling the genetic legacy of commercial whaling in bowhead whales and narwhals

This study examines the genetic impacts of commercial whaling on bowhead whales and narwhals, finding that bowhead populations experienced a sharp decline in effective population size while narwhals showed recent growth.

Elevated temperatures reduce population-specific transcriptional plasticity in developing lake sturgeon (Acipenser fulvescens)

The paper shows that higher temperatures reduce transcriptional plasticity in lake sturgeon populations, with southern populations showing greater plasticity than northern ones.

Genomic architecture of migration timing in a long-distance migratory songbird

This study identifies a genomic region on chromosome 1 associated with migration timing in purple martins, showing genetic basis and reduced adaptive potential to recent environmental changes.

Genomic signals found using RNA sequencing support conservation of walleye (Sander vitreus) in a large freshwater ecosystem.

The paper uses RNA sequencing to analyze genetic variation in walleye from Lake Winnipeg, finding low population divergence and latitudinal transcript variation, suggesting a connected metapopulation for conservation management.
