Descripción del nido de dos especies de Thomasomys (Cricetidae) de un bosque alto-andino en Ecuador

Abstract: Nests are described for Thomasomys aureus and T. paramorum in a high Andean forest in northern Ecuador. Nests of T. aureus were found in the tree canopy to 6 and 7 m in height andthose for T. paramorum were located under the roots from 15 cm to 1.5 m above the surface.

“…These species may require more vertical structural complexity than was present in the mid-successional woodland. For instance, Brito et al [35] found that T. aureus relies on a habitat's vertical structure and complexity moving through trees and nesting above ground more frequently than T. paramorum. Temperatures within intact Polylepis woodlands have less diurnal variation and are less susceptible to frost than nearby páramo [14], which therefore opens the possibility that the microclimate, in addition to habitat complexity, may affect the viability of forest specialists outside of canopied forests.…”

“…Temperatures within intact Polylepis woodlands have less diurnal variation and are less susceptible to frost than nearby páramo [14], which therefore opens the possibility that the microclimate, in addition to habitat complexity, may affect the viability of forest specialists outside of canopied forests. T. paramorum, a habitat generalist, [19,[35][36][37] was abundant in both the mid-successional and intact woodland. We predicted that two ground dwelling species, N. latebricola and A. mollis would occur in different abundances in the intact and mid-successional woodlands because N. latebricola was more associated with forested habitats than the páramo in this region [37].…”

“…Para la descripción del nido se consideraron las siguientes medidas sugeridas por Brito et al [10]: longitud, ancho, altura y peso del nido, diá-metro de la entrada, orientación relativa en el espacio y materiales de construcción. expedición realizada en junio 2014 a Sardinayacu (02…”

“…Briani et al [11] menciona que la rata Nectomys scuamipes construye nidos en troncos caídos y Oryzomys intermedius bajo o dentro de troncos caídos y dentro de raíces aéreas de palmas, siempre cerca de cuerpos de agua; Udrizar-Sauthier et al [12] reportan los nidos de Oryzomys sp. e Hylochilus brasiliensis en sitios elevados a pocos centímetros de la superficie del agua; Brito et al [10] reportan que Thomasomys aureus y T. paramorum también construyen sus nidos cerca a los cuerpos de agua, mientras que Rengifo y Aquino [13] dan a conocer un nido de Scolomys melanops en un árbol caído a 50 m del cuerpo de agua más cercano.…”

“…Para los análisis acústicos se utilizó el programa Adobe Audition 3.0 a una frecuencia de muestreo de 44.1 kHz y 16 "bits" de resolución y en la diagramación del oscilograma y espectrograma se utilizó el programa Raven 1. El ratón andino de páramo Thomasomys paramorum habita matorrales de Polylepis, páramo arbustivo y bosques de ecotono [22,23]. Las vocalizaciones una hembra adulta de T. paramorum eran imilares a un chasquido de frecuencia modulada, con una frecuencia dominante de 1.65-1.89 kHz (X =1.74 ± 0.10), generando un armónico cuya frecuencia era de 3.40-4.04 kHz (X =3.64 ± 0.24) (Fig.…”
