espanolEn este articulo tratamos de describir la composicion de la dieta de Sus scrofa en tres ecorregiones brasilenas caracterizadas por un mosaico de bosques y pastizales: la pampa, el bosque de araucaria y el pantanal. Evaluamos los riesgos que la especie puede representar para la agricultura y la conservacion de la biodiversidad analizando el contenido estomacal de 118 jabalies. Analizamos sus habitos alimentarios en cada ecorregion utilizando el analisis de componentes principales y comprobamos que la dieta varia en funcion de las caracteristicas de cada individuo mediante un analisis de la redundancia. Representamos la composicion de macronutrientes en un espacio multidimensional mediante un diagrama triangular rectangular. El jabali presento una dieta diversa, influida por la estacion, el momento del dia y la disponibilidad local de recursos. Los cereales y hierbas cultivados fueron los productos consumidos mas habitualmente, lo que apunta una ingesta elevada de carbohidratos. Los danos provocados a la agricultura podrian ser elevados dado el gran consumo de cereales cultivados. El crecimiento y la expansion de la poblacion pueden verse limitados por la escasa disponibilidad de proteina en las ecorregiones. EnglishWe aimed to describe the composition of Sus scrofa diet in three Brazilian ecoregions characterized by a mosaic of forests and grasslands: Pampa, Araucaria Forest and Pantanal. We evaluated the possible risks that the species may represent for agriculture and conservation of biodiversity by analyzing the stomach content of 118 boars. We examined dietary patterns in each ecoregion using PCA (principal component analysis) and verified how diet varies according to individual attributes through redundancy analysis. We visualized the composition of macronutrients in a multidimensional space by means of RMT (right–angled mixture triangle). The wild boars presented a diverse diet, influenced by season, time of day, and local availability of resources. Cultivated grains and herbs were the most commonly consumed items, leading to a high carbohydrate intake. Damage to agriculture is potentially high given the large consumption of cultivated grains. Population growth and expansion may be limited by the low availability of protein in the ecoregions.
