This study identifies an expansion threshold in species range dynamics caused by eco-evolutionary feedback, where genetic drift overwhelms selection, leading to range contraction or fragmentation.

This paper extends local adaptation models to multi-habitat scenarios, showing how polymorphism persistence depends on migration, selection pressure, and habitat symmetry.

The paper explains why species ranges have limits by showing genetic drift reduces variance needed for adaptation, leading to sharp range margins even without abrupt environmental changes.
