Resumen

En este estudio describimos la estrategia alimentaria de la cabra montesa ibérica Capra pyrenaica Schinz, 1838 en dos sierras adyacentes recientemente recolonizadas por la especie, Gerês y Amarela, en el Parque Nacional da Peneda-Gerês (PNPG, Portugal). Para ello estudiamos la composición y selección de la dieta de la cabra montesa utilizando el análisis microhistológico de heces. La cabra montesa presentó un comportamiento intermedio ramoneador - pastador en ambas áreas, aunque con una mayor tendencia al ramoneo en Amarela y al pastoreo en Geres. También se observó un cambio importante en la dieta de primavera en ambas sierras caracterizado por el aumento en el consumo y preferencia por gramíneas. Esta estrategia se mantuvo en verano apenas en Amarela. Los resultados obtenidos son congruentes con el comportamiento generalista ampliamente descrito para la cabra montesa en otras regiones de la Península Ibérica y sugieren que su estrategia alimentaria en el PNPG depende de la distribución espacial de los recursos, en particular de las herbáceas graminoides, y de la carga y gestión ganaderas en la región
