Resumen

CARSON, HAMPTON L.. Danko Brncic and the flower-flies. Rev. chil. hist. nat. [online]. 2001, vol.74, n.1, pp.33-38. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2001000000008.

This is a personal essay commemorating Brncic as a keen naturalist/evolutionist in the best Darwinian sense. His innate curiosity, so important in a scientist, led him to the discovery of cenain unique drosophilid flies in Chile. The life cycle of one species of flower-fly (Drosophila flavopilosa) is of special interest. Females oviposit in fresh flowers of a solanaceous plant that is widespread in Chilean valleys. Twenty years of combined ecological and genetic work, carried out on this species, pioneers the use of a highly specialized Drosophila species in the study of population genetics and evolution. Many eco-genetic features are revealed that are important supplements to observations made on the widely-studied generalist species of the genus

Palabras clave : flower-breeding Drosophila; genetic specialization; ecology; population genetics; evolution.
