Abstract

espanolLa ardilla gigante hindu (Ratufa indica) es una de las cuatro especies de ardilla gigante del mundo. Se trata de una especie endemica de la India, pero sus poblaciones se encuentran muy fragmentadas. La ecologia de las ardillas en Asia se ha estudiado poco, lo que ha entorpecido los esfuerzos de conservacion y de gestion. Se estudiaron los habitos de nidificacion y alimentacion de la ardilla gigante hindu durante la primavera en el refugio de vida silvestre de Karpalat, en la India. Se inspeccionaron 122,5 km de senderos naturales para la observacion directa de estas ardillas, sus nidos e indicios de alimentacion, y se muestrearon varios cuadrantes para evaluar la disponibilidad de recursos. Para analizar los datos sobre preferencias, se emplearon los indices de la funcion de seleccion de recursos de Manly y del logaritmo de la prueba de razon de verosimilitud. El promedio del indice de encuentros de la ardilla gigante hindu fue de 0,57 (± 0,18 DE) individuos/km. Haldinia cordifolia (Wi = 4,899; p EnglishThe Indian giant squirrel (Ratufa indica) is one of four species of giant squirrels in the world. It is endemic to India and its populations are severely fragmented. The ecology of squirrels in Asia has been little studied, hindering conservation and management efforts. We studied the Indian giant squirrel’s nesting and feeding habits during spring in the Karlapat Wildlife Sanctuary, India. We surveyed 122.5 km of natural trails for direct observation of these squirrels, their nests and feeding evidence, and we sampled plot–based quadrats to assess the availability of resources. We used Manly’s resource selection function and log–likelihood test ratios to analyse the data for preference. The mean encounter rate of the Indian giant squirrel was 0.57 (± 0.18 SD) individuals/km. Haldinia cordifolia (Wi = 4.899, p Nest site preference was for taller tree species. As current management practices directly damage the preferred nesting sites and food resources, our findings aim to promote effective conservation of the Indian giant squirrel.
