Population dynamics in extreme environments: shared histories of strong selection lead to predictable patterns across separate high-elevation populations of small mammals

The paper examines genetic and phenotypic variation in deer mice across elevation gradients, finding predictable patterns in extreme environments that could inform species vulnerability to environmental change.

Reduced baseline male fertility and increased sensitivity to hypoxic stress in high-elevation deer mice

This study finds that high-elevation deer mice have reduced baseline fertility and greater sensitivity to hypoxia compared to low-elevation mice, with gene expression changes suggesting adaptive testicular regression.
