“…The rodents Cuniculus paca, Sciurus aureogaster, Peromyscus leucopus, and Chaetodipus sp. found at the oak forest in Tamasopo are widespread, maintaining viable populations in small fragments of forest surrounded by crop land as in the study area (Navarrete-Gutiérrez et al 1996;Núñez-Garduño 2005;Rojas-Rojas and Barboza-Rodríguez 2007;Rodríguez-Macedo et al 2014;Martínez-Ceceñas et al 2020). As opportunistic species, they predate on D. edule seeds despite the toxin content, adapting their diet to the available resources.…”

“…The robust methods utilized in these analyses are applied to ield data similar to those gathered by workers in oak forests in Central and South America (Fleming 1974, Van den Bergh & Kappelle 1998, Vazquez et al 2000, Sánchez-Cordero 2001, and Rojas Rojas & Barboza Rodriguez 2007. We can extract more information from the data after these analyses than can be obtained by analysis of the very same data using less robust methods.…”

“…Like investigations of larger mammals in these systems (Walker & Cardenas 2004, Cujar-Tovar 2006, Tobler et al 2006, these studies have depended upon indices of activity rather than population size estimations to assess habitat relationships and community dynamics. Attempts to determine population size or relative abundance often have used less precise estimation methods such as Minimum Number Left Alive (Vazquez et al 2000), Lincoln Index (Fleming 1974), or JollySeber methods (Rojas Rojas & Barboza Rodriguez 2007). Recent work using more robust population estimation methods such as available in Program Capture (Rexstad & Burnham 1991) or Program Mark (White & Burnham 1999) has proved to be very useful and informative comparing small mammal use of different habitats (e.g.…”

“…Las abundancias de las 7 especies registradas fueron significativamente variables a lo largo del tiempo de muestreo, sin embargo, no se encontró una relación estadística entre estas y la precipitación, excepto en el caso de R. fulviventer que mostró un aumento hacia los meses con mayor lluvia. El aumento en la abundancia relacionado con la precipitación se ha reportado para otros roedores neotropicales, tales como Peromyscus mexicanus (Rojas-Rojas y Barboza-Rodríguez, 2007), Heteromys catopterius, Neacomys tenuipes, Nephelomys caracolus, Oligorizomys trinitatis, O. fulvescens, Rhipidomys venezuelae, R. venustus, Sigmodon hirsutus (García et al, 2013), entre otros. Estos aumentos en la abundancia pueden deberse a que el período lluvioso propicia la producción y caída de frutos y semillas (Rojas-Rojas y Barboza-Rodríguez, 2007), así mismo, la permanente nubosidad que caracteriza el bosque altoandino en este período reduce el riesgo https://doi.org/10.…”
