Resumen
THE ISOLATED WATERSHEDS OF THE SOUTHWESTERN ANDEAN ALTIPLANO CONSTITUTE A NATURAL LABORATORY TO STUDY THE EVOLUTIONARY DIVERGENCE OF FRESHWATER BIOTA. FIELD OBSERVATIONS SHOWED THAT BIOMPHALARIA SNAILS FROM PARINACOTA, COLPA, AND CAQUENA HAVE DIFFERENT SHELL SIZES. WE PERFORMED MORPHOMETRIC ANALYSIS AND COMMON GARDEN EXPERIMENT TO EVALUATE WHETHER THE OBSERVED SHELL VARIATION HAS A GENETIC BASE AND IF THIS VARIATION IS MANIFESTED IN OTHER MORPHOLOGICAL CHARACTERS AND LIFE HISTORY TRAITS.
