Genetic drift in range expansions is very sensitive to density feedback in dispersal and growth

Autor: Birzu, Gabriel, Matin, Sakib, Hallatschek, Oskar, Korolev, Kirill S.

Theory predicts rapid genetic drift during invasions, yet many expanding populations maintain high genetic diversity. We find that genetic drift is dramatically suppressed when dispersal rates increase with the population density because many more mi

Neither pulled nor pushed: Genetic drift and front wandering uncover a new class of reaction-diffusion waves

Autor: Birzu, Gabriel, Hallatschek, Oskar, Korolev, Kirill S.

Traveling waves describe diverse natural phenomena from crystal growth in physics to range expansions in biology. Two classes of waves exist with very different properties: pulled and pushed. Pulled waves are driven by high growth rates at the expans
