Dynamic response to mountain breeze circulation in Alchichica, a crater lake in Mexico [PDF]

Geophysical Research Letters, 2006
In this paper we discuss the dynamic response to mountain breeze circulation in Alchichica, a deep crater lake in Mexico. A numerical model was used to simulate integrated drift currents based on wind data sampled at 1‐h intervals. The results are compared with those measured by an ADCP.

TEMPORAL VARIATION IN THE ABUNDANCE OF POBLANA ALCHICHICA IN NEAR-SHORE HABITAT OF THE HIGH ELEVATION LAKE, LAGO DE ALCHICHICA, PUEBLA, MEXICO

, 2012
"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.

Geomicrobiology of Alchichica alkaline lake microbialites (Mexico)

, 2012
Les stromatolites sont des structures organo-sédimentaires formées grâce à l'activité des microorganismes. Ils dominent le registre fossile Précambrien et sont parmi les plus anciennes traces potentielles de vie sur Terre (datées à 3,5 Ga). Cependant les processus biotiques et abiotiques à l'origine de leur formation restent peu compris et ouvrent des ...
