Climatic differences among species distributions and their physiological and genomic basis in geomitrid land snails

To show evolutionary adaptation to the local climate niches within or among species, two routes can be pursued. The first is to show the existence of heritable constant fitness-related phenotypic differences among populations and species. The second involves identification of genomic differences related to climatic niche differences We studied climate niche evolution and its genomic basis within and among sister species of the geomitrid genus Candidula, C. unifasciata (Poiret 1801) and C. rugosiuscula (Michaud 1831).
