CRUZ-SAENZ, Daniel  y  LAZCANO, David. Biological and ecological aspects of Xantusia sanchezi, an endangered lizard in an oak forest in the state of Jalisco, Mexico. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.1, pp. 129-132. ISSN 2007-8706.

Xantusia sanchezi is an endangered species that is endemic to Mexico and is known only from the states of Jalisco and Zacatecas. We studied a population from a locality known as Huaxtla, in the municipality of Zapopan in the state of Jalisco. Sampling was conducted over a period of 7 months in an area of 1.5 hectares of grassland and oak forest with boulders. Collected data included: body measurements (total length, snout-vent length, tail length, head length, head width, head height, femur length, and femoral pores), sex, weight, habitat and average temperature and humidity. Habitat characterization was made using a coverage analysis. A total of 29 individuals were captured with 7 re-captures. This work provides the first data on the biology and ecology of this species, which is known in Jalisco from only a small area under tremendous threat due to urban development.
