Reconstructing the origins of high-alpine niches and cushion life form in the genus Androsace S.L. (Primulaceae).
Relatively, few species have been able to colonize extremely cold alpine environments. We investigate the role played by the cushion life form in the evolution of climatic niches in the plant genus Androsace s.l., which spreads across the mountain ranges of the Northern Hemisphere. Using robust methods that account for phylogenetic uncertainty, intraspecific variability of climatic requirements...
متن کاملTraces of ancient range shifts in a mountain plant group (Androsace halleri complex, Primulaceae).
Phylogeographical studies frequently detect range shifts, both expansions (including long-distance dispersal) and contractions (including vicariance), in the studied taxa. These processes are usually inferred from the patterns and distribution of genetic variation, with the potential pitfall that different historical processes may result in similar genetic patterns. Using a combination of DNA s...
متن کاملTaxonomy and nomenclature of the polymorphic European high mountain species Androsace vitaliana (L.) Lapeyr. (Primulaceae)
Androsace vitaliana (syn. Vitaliana primuliflora; Primulaceae) has been subject to several taxonomic treatments, whose conclusions ranged from a single species with numerous infraspecific taxa to several species usually without infraspecific taxa. Here, following molecular investigation, several taxonomic changes are made. A single species with the following infraspecific taxa is recognized: su...
متن کاملConservation of Endangered Species: Androsace mathildae Levier (Primulaceae) in Central Italy
Climate change influences the distribution of species, causing the displacement of distribution areas, both in altitude and latitude. The potentially most climate change-susceptible taxa are those of mountain peaks, with limited distribution areas, such as rare or endemic species. In this paper, we deepened the study of Androsace mathildae Levier, a plant that lives in Central Italy over 2500 m...
