Life at high altitude is associated with many physiological challenges, including exposure to conspicuous stressors such as hypoxia and extreme cold. Consequently, most animals living at high altitude have been under strong selection to develop adaptations to these challenges. Unveiling adaptations in other high-altitude-living animals, including nonhuman primates, could therefore help illuminate the mechanisms underlying adaptive evolution of myriad traits. Here, we investigated the genetic adaptations to high altitude in a novel nonhuman primate model, the gelada monkey.

Organisms respond to climate change via tracking through space or time, phenotypic plasticity, or evolution.  A key question is whether plasticity facilitates evolution by enabling persistence or hinders evolution by buffering selection. I will present a phenotype-based forecasting framework for montane butterflies, which finds that plasticity facilitates evolution by reducing fluctuations in selection, particularly in more seasonal environments.  Repeating historic lab and field studies and examining museum specimens reveals both the viability of evolutionary responses and t
