How biodiversity is affected by speciation disruptive stabilizing and directional selection?

Biodiversity is influenced by the type of natural selection acting on species. Disruptive selection can increase diversity by favoring extreme phenotypes over intermediate ones, potentially leading to speciation as populations diverge. Stabilizing selection tends to reduce variation by favoring average traits, which can limit the emergence of new species and decrease biodiversity. Directional selection shifts the population's traits in one direction, which may enhance or reduce diversity depending on the environmental context and the traits favored.
