ABSTRACT

Extensive debate has surrounded the application of alternative species concepts in Ornithology. The biological species concept (BSC) and phylogenetic species concept (PSC) have typically been set in opposition, with extensive debate on the relative merits of each. An alternative is the evolutionary species concept (ESC), which offers a perspective similar to that of the PSC, yet with several significant differences. To date, no major avifauna has been examined and compared among taxonomic viewpoints. Herein, we develop an alternative phylogenetic/evolutionary species taxonomy to the current BSC treatment for the more than 1000 bird species of Mexico. A total of 135 biological species was divided to produce a total of 323 phylogenetic/evolutionary species, 122 of which represent “new” endemic forms in Mexico.

Key words: Species concepts, avifauna, Mexico

RESUMEN

Gran debate ha rodeado la aplicación de conceptos de especie alternativos en la Ornitología. El concepto biológico de especie (CBE) y el concepto filogenético de especie (CFE) han estado típicamente en contraposición, existiendo mucha discusión acerca de las ventajas relativas de cada uno. Una alternativa es el concepto evolutivo de especie (CEE), que ofrece una perspectiva similar a la del CFE, aunque con algunas diferencias importantes. A la fecha, no se ha examinado y comparado alguna avifauna regional desde el punto de vista del CBE y de los conceptos alternativos. En este trabajo desarrollamos una taxonomía alternativa a la existente en la actualidad bajo el CBE para las más de 1000 especies de aves de México. Un total de 135 especies biológicas fue dividido hasta producir un total de 323 especies filogenético/evolutivas, 122 de las cuales son “nuevas” formas endémicas al país.

Palabras-claves: Conceptos de especie, avifauna, México.
