Poblana alchichica: A threatened silverside species?

SIL Proceedings, 1922-2010, 2010
The status of local endemic species such as Poblana alchichica is difficult to assess, and therefore conservation measures are not efficiently implemented. However, in recent years several methods have helped compare status of different species based on objective criteria.

Initial field data for the Critically Endangered Alchichica salamander Ambystoma taylori from Lago Alchichica, Mexico

The Herpetological Bulletin
The Lake Alchichica salamander Ambystoma taylori is a Critically Endangered, neotenic inhabitant of a single, hyposaline lake in Puebla, Mexico. Between 2015 and 2018, initial field data were collected for this understudied species, to inform future conservation action. Using unbaited submerged passive traps at depths of 0–<10, 10–<20 and 20–30 m,

Hidrogeoquímica de salinas Zapotitlán y los lagos-cráter Alchichica y Atexcac, Puebla [PDF]

open access: yesIdesia, 2014
In this study we carried on the experimental evaporation of brines from two saline crater-lakes: Alchichica and Atexcac, in the Basin of the Oriental, Puebla, and from a saline spring, Salinas Chiquitas, Zapotitlan, Puebla, thus documenting patterns of evolution to higher stages of concentration of solutions.

A note on the effects of an individual large rainfall event on saline Lake Alchichica, Mexico

Environmental Geology, 2007
The present study reports on perturbations of the water column by large rainfall at Lake Alchichica, a saline lake in Central Mexico. Alchichica is located in the “Llanos de San Juan,” a high-altitude plateau with a minimum elevation of 2,300 m above sea level. The climate is arid with annual precipitation less than 400 mm and annual evaporation of 500–

Nitrogen fixation patterns displayed by cyanobacterial consortia in Alchichica crater-lake, Mexico

Hydrobiologia, 2002
Alchichica is a saline crater-lake located in Mexico. Tufa grows on its periphery and a wind-driven Nodularia cf. spumigena bloom occurs annually. Fixation rates were assayed by the acetylene reduction method. Here, we describe the patterns of nitrogen fixation on two tufa forms before, during and after the bloom, as well as those from the planktonic ...

Late Pleistocene to Holocene activity of Alchichica maar volcano, eastern Trans-Mexican Volcanic Belt

Journal of South American Earth Sciences, 2020
Abstract Detailed volcano-stratigraphy and 40Ar/39Ar dating are used for the first time to reconstruct the eruptive evolution of the Alchichica maar and to contribute to the understanding of maar volcanism within the eastern Trans-Mexican Volcanic Belt (TMVB).
