Northern Saw-whet owl feathers contain porphyrins, which fluoresce under UV but break down over time. Older feathers thus glow less intensely than newly-molted feathers. Here you can see three generations of feathers, making this an after second year bird. 🧠

How do major evolutionary shifts leave their mark over deep time? Across mammals, transitions into new niches often drove skull evolution beyond what genetic drift alone can explain. @fmachado.bsky.social @damelo.net @apenna.bsky.social @agporto.bsky.social academic.oup.com/evlett/advan...

Invasion of new adaptive zones retains telltale signs of directional selection at macroevolutionary scales in mammals

Abstract. Directional selection is often viewed as a transient force in macroevolution, with its signal eroded over time by stabilizing and fluctuating sel

Topographic variation shapes organismal responses across mountain landscapes - Nature Climate Change

The authors developed simulations to examine the role of topographic variation in mediating species response to climate change. They show that topographic variation can reduce energy expenditure by up...

🐟🚨 New paper! 🚨🐟 Where do behavioral differences come from? Early life environment clearly matters... ...or not? Early environment affected behavior, but NOT how different individuals became from each other. Those differences were seeded before birth through factors OTHER than genetic variation 🤯
