Resumen

Se utilizó polvo fluorescente para identificar las preferencias de Peromyscus maniculatus (Rodentia, Cricetidae) por distintos rasgos del microhabitat y para examinar el significado ecológico de tales preferencias. Se realizó análisis de datos por sexo. Los resultados muestran que P. maniculatus utilizaró áreas sin cobertura vegetal del estrato más alto, o áreas con cobertura de arbustos bajos o plantas herbáceas en el estrato bajo, y hojarazca y broza leñosa como sustrato. Los ratones prefirieron la cobertura de árboles desciduos en el estrato de vegetación más alto, tronco caídos de 5 a 10 cm de diámetro como cobertura del estrato bajo, y hojarazca como sustrato. La cobertura de pastos y el suelo desnudo fueron evitados. Los machos fueron indiferentes a la cobertura de arbustos bajos y evitaron la cobertura de dicotiledóneas herbáceas, mientras que las hembras prefirieron arena como sustrato y fueron indiferentes en el uso de rocas.
