Food Preference of Cavia magna (Rodentia: Caviidae) on a Subtropical Island in Southern Brazil

Abstract This study aimed to link the plants consumed by Cavia magna and their availability in the environment, (Ilha dos Marinheiros) determining its food preference. In the environment, 96 species were recorded. Twenty-four plant species were identified in the fecal samples. There wasn’t significant difference in the composition of plant species among seasons, although the variation was significant between the island’s northern and southern areas concerning the fecal samples. Mantel test’s results supported that the availability of vegetation has significant influence on the species c...
