Microclimatic variation regulates seed germination phenology in alpine plant communities
Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.
