CRUZ, Laura E.; LORENZO, Consuelo; RETANA, Oscar G.  y  SANTIZ, Eugenia C.. Interspecific variability in the abundance of small rodents in the highlands of Chiapas, Mexico. Therya [online]. 2010, vol.1, n.2, pp.129-135. ISSN 2007-3364.  https://doi.org/10.12933/therya-10-11.

We provide data on small rodent species abundances and community composition over a one year period at four locations comprising two contrasting habitats, agricultural areas (corn fields) and ecological reserves, in the Municipality of San Cristóbal de Las Casas, Chiapas. 469 captures of nine species of murid rodents were recorded in total, the most abundant of which included Reithrodontomys fulvescens, Sigmodon hispidus, and Peromyscus levipes. The highest number of captures (272) was recorded during the dry season, and the highest species richness (7) during the rainy season in an agricultural area. We found significant statistical differences in number of captures between the dry and wet seasons only for the Ecological Reserve Moxviquil.
