Toward temporally calibrated biomarkers of heat stress in free-living songbirds

The paper develops blood-based transcriptomic biomarkers for detecting past heat stress in free-living birds by analyzing gene expression changes in Tree Swallows exposed to controlled heat.

Song complexity in suboscine birds: evolutionary drivers and ecological constraints

This study uses Bayesian phylogenetic models to analyze song complexity in suboscine birds, finding that sexual selection reduces complexity while territoriality increases it, challenging the dominance of sexual selection as the primary driver.

Divergent climate impacts despite similar response to temperature in a widespread aerial insectivore

The paper shows that tree swallow populations have similar sensitivity to temperature but differ in vulnerability due to timing constraints and exposure to warming.

Efficient Inference of Macrophylogenies: Insights from the Avian Tree of Life

This study evaluates methods for inferring large-scale avian phylogenies, finding that fast tree search approaches balance computational efficiency and accuracy.
