Feeding habits of capybaras (Hydrochoerus hydrochaeris, Linnaeus 1766), in the Ecological Reserve of Taim (ESEC - Taim) - south of Brazil

The aim of this study was to determine feeding habitats of capybaras in the ESEC-Taim (RS, Brazil), using microhistological analyses of feces. Data were analyzed seasonally. In 172 samples analyzed, 17 species were identified, with predominance of Poaceae. Zizaniopsis bonariensis was the most freque...

description The aim of this study was to determine feeding habitats of capybaras in the ESEC-Taim (RS, Brazil), using microhistological analyses of feces. Data were analyzed seasonally. In 172 samples analyzed, 17 species were identified, with predominance of Poaceae. Zizaniopsis bonariensis was the most frequent species in winter (38%), spring (32%) and summer (26.5%) and Paspalum disthichum in fall (31.5%). A observed increase in vegetation consumption during summer might be due to the food quality. Capybaras showed an opportunistic behavior in the winter and summer and a more selective behavior in spring and fall. Capybaras from the ESEC-Taim varied diet according to the season and alimentary availability.<br>O principal objetivo deste estudo foi determinar os hábitos alimentares das capivaras na ESEC-Taim baseado na análise microhistologica de suas fezes. Os dados foram analisados sazonalmente. Em 172 amostras analisadas, foram identificadas 17 espécies, com predominância de Poaceae. Zizaniopsis bonariensis foi a espécie mais freqüente no inverno (38%), primavera (32%) e verão (26,5%) e Paspalum disthichum no outono (31,5%). O aumento no consumo da vegetação durante o verão pode ser explicado devido à qualidade da vegetação. As capivaras mostram um comportamento de oportunismo nas estações de inverno e verão e um comportamento mais seletivo na primavera e outono. Concluindo, as capivaras da ESEC-Taim variam sua dieta de acordo com a estação e a disponibilidade de comida.
