The paper develops BEAC, an epigenetic clock for birds, validated across multiple species and showing strong predictive performance for chronological age.

This study examines how subtle temperature changes during early life affect gut microbiome diversity and composition in wild birds, finding that rearing environment has a greater influence than genetics.

This study examines how early-life adversity affects growth and mitochondrial metabolism in king penguin chicks, finding higher mitochondrial metabolism in late-born chicks but no clear link to growth patterns.

Both experimental nestbox heating (+2.83°C) and cooling (-1.72°C) during early postnatal development significantly shorten day-13 relative telomere length in wild pied flycatcher nestlings without altering body mass.

The paper shows that early-stage altricial bird embryos express genes involved in thyroid hormone pathways, suggesting they can respond to maternal thyroid hormone signals.
