Abstract
Less is known about effects of ice ages in southern South America than in Europe and North America. The Andes in southern Chile (south of Temuco) were completely glaciated, whereas only descent of local glaciers occurred throughout other Andean regions. Species of South American Hypochaeris sect. Achyrophorus are members of the high-Andean flora (Chile and Argentina) and serve to test hypotheses of biogeographic effects of ice ages in this region. We have analyzed three species that differ in ecology and reproductive modes: H. tenuifolia, a perennial allogamous pioneer on exposed lava slopes, and H. acaulis and H. palustris, both inbreeders localized in moist seeps along small arroyos.
