- TEMPORAL VARIATION IN THE ABUNDANCE OF POBLANA ALCHICHICA IN NEAR-SHORE HABITAT OF THE HIGH ELEVATION LAKE, LAGO DE ALCHICHICA, PUEBLA, MEXICO GUILLERMO A. WOOLRICH-PIÑA GEOFFREY R. SMITH JULIO A. LEMOS-ESPINAL RAYMUNDO MONTOYA-AYALA LUIS E. ÁVILA-BOCANEGRA EDUARDO BENAVIDES GARDUÑO Biología salinity Abundance temperature dissolved oxygen Poblana Alchichica The distribution and abundance of organisms within a pond or lake can reflect the result of a variety of factors. We examined the abundance of the endemic fish, Poblana Alchichica, in Lago de Alchichica, Puebla, Mexico, as well as how the abundance varied among months. Dissolved oxygen, temperature, and salinity varied among months. The abundance of Poblana Alchichica peaked in December and February. For the months when fish were observed, their abundances were positively related to dissolved oxygen concentration and were generally not related to temperature. Our results provide evidence that there is substantial seasonal variation in the abundances of Poblana Alchichica and that within months, their distributions are likely driven by dissolved oxygen than either temperature or salinity. 2012 artículo científico 0120-548X https://www.redalyc.org/articulo.oa?id=319028009015 en http://www.redalyc.org/revista.oa?id=3190 Acta Biológica Colombiana application/pdf Universidad Nacional de Colombia Acta Biológica Colombiana (Colombia) Num.1 Vol.17
