Microhabitat use by sigmodontine rodents in crop-field borders of pampean agroecosystems

Abstract

The aims of this work were to assess the relevance of some variables in the use of microhabitats by two rodent species, and to contribute to models predicting their presence in agroecosystems in the south of Córdoba province, Argentina. Rodent sampling was conducted in crop-field borders seasonally from spring 2013 to winter 2014. Floristic composition, litter cover and bare soil percentage were determined at each trap site. Variables influencing the use and not-use of trapping stations by each species were identified with a logistic regression. We suggest a differential microhabitat use by both species.
