Abstract:Habitat specialization can lead to naturally fragmented populations separated by unoccupied habitats that comprise potential barriers to dispersal. Habitat fragmentation can result in phenotypic divergence between populations, and eventual speciation. We investigate trait divergence in a habitat specialist plant species –Impatiens lawii– that is specialized on rock outcrops in the Western Ghats mountains of India. We compare trait divergence in this species with that in a closely related species,I. oppositifol… Show more
