Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.
