Variación geográfica de la recompensa floral de <i>Calceolaria polyrhiza</i> (Calceolariaceae): Influencia de factores bióticos y abióticos

Geographic variation of floral reward in Calceolaria polyrhiza: influence of biotic and abiotic factors. The study of intraspecific differentiation of floral characters involved in plant-pollinator interaction, and of its relationship with biotic and abiotic factors is essential to elucidate the factors affecting biological adaptation and specialization. Systems involving oil-secreting plants and oil-collecting bees are considered one of the most specialized plant-pollinator mutualisms. In this study, using thin layer chromatography (TLC), we analyze composition of floral oils in 12 natural populations of Calceolaria polyrhiza, a species endemic to Patagonia. For each sampling site we obtained data on…
