USO DEL HÁBITAT, DINÁMICA POBLACIONAL Y ESTACIONALIDAD REPRODUCTIVA DE ROEDORES EN EL ALTIPLANO POTOSINO, MÉXICO

Eric Mellink Bijtel

Resumen


RESUMEN. En este trabajo se reportan las preferencias de hábitat, dinámica poblacional y estacionalidad repoductiva de Perognathus jlavus, Chaetodipus hispidus, C. nelsoni, C. penicillatus, Dipodomys ordii, D. merriami, Liomys irroratus, Reithrodontomys fulvescens, Peromyscus maniculatus, Onychomys arenicola y Sigmodon hispidus en asociación con tres sistemas agrícolas áridos, sus bordes y sus alrededores no cultivados, en el Altiplano de San Luis Potosí, México. Al parecer, la cubierta herbácea es la característica más importante del hábitat. Los roedores presentaron dos patrones estacionales diferentes: la mayoría tuvo el nivel poblacional más alto durante el verano, aunque algunos lo presentaron en invierno. A pesar de las diferencias en la estacionalidad de la población, todos los roedores tuvieron su pico reproductivo durante el verano, relacionado en alguna forma con la época de lluvias.

 ABSTRACT. This work reports on the habitat preferences, population dynamics and reproductive seasonality of Perognatusflavus, Chaetodipus hispidus, C. nelsoni, C. penicillatus, Dipodomys ordii. D. merriami, Liomys irroratus, Reithrodontomys fulvescens, Peromyscus maniculatus. Onychomys arenicola and Sigmodon hispidus in association with three dry farming systems and their unfarmed neighboring areas and borders, in the San Luis Potosí Plateau, Mexico. lt was found that herbaceaous cover seemed to be the most important habitat characteristic. Rodents presented two different seasonal patterns: most had their highest populations during the summer. But some did so during the winter. Despite differences in population seasonality, all rodents had their highest reproductive rates during the summer, related in some form with the rainy season.
