“…Figure 1 shows the topology of the portion of the oryzomyine phylogeny encompassing the species sampled in this study (Weksler 2006). Although relevant ecological features such as dietary preferences are not known in detail for most species, their wide distribution, ranging from habitats as distinct as the Peruvian desert (e.g., Oryzomys xantheolus ; Guabloche et al 2002) to rainforest streams (e.g., Nectomys squamipes ; Hershkovitz 1944), strongly suggests that these species span a wide dietary spectrum (see Supporting Table S1).…”

“…Análisis de la dieta.-Los estómagos fueron separados del tracto digestivo, su contenido homogenizado (Meserve 1981) y luego separado en dos fracciones: partículas pequeñas (< 0,7 mm) y partículas grandes (> 0,7 mm) (Guabloche et al 2002). Cada fracción fue examinada usando un estéreomicroscopio a 40 aumentos en no menos de cinco campos ópticos utilizándose el porcentaje de cobertura de campo como una medida del volumen (Solari 1997).…”

“…Perú posee una gran diversidad de roedores, conociéndose no menos de 162 especies (Pacheco et al 2009); sin embargo, pocas especies cuentan con estudios de contenido y variabilidad de su dieta. Después de los estudios pioneros de Dorst (1972) y Pizzimenti y De Salle (1980) muy pocos trabajos sobre análisis de dieta han sido publicados, como los de Guabloche et al (2002) con Aegialomys xanthaeolus (reportado como Oryzomys xantheolus) y Solari (2007) con roedores altoandinos del Parque Nacional del Manu. Otros reportes cualitativos de dieta en algunas especies incluyen a Luna y Patterson (2003) para Rhagomys longilingua y Pacheco y Peralta (2011) para Rhipidomys ochrogaster.…”

“…1991; Dillon 1997). Lomas are highly seasonal habitats in the Pacific coastal desert of Peru and northern Chile that occur between approximately 50–1000 m altitude with vegetative growth mainly between August and November (Guabloche et al . 2002).…”
