First record of plastic ingestion byCerdocyon thous (Carnivora, Canidae) in northeastern Brazil ABSTRACT Cerdocyon thous is a neotropical canid often found in natural, fragmented, altered and agricultural environments. Its generalist diet includes plant and animal items, as well as items generated from human activities, such as cultivated fruits. We report the first consumption of plastic by this species in the semiarid region of Brazil, determined by three fragments found in the stomach of a road-killed individual. This finding highlights the problem of inadequate disposal of domestic waste, and the present threat of inorganic material in the food chain.

We investigated the diet and trophic niche of Kerodon rupestris in Northeastern Brazil for 12 months. The influence of precipitation was evaluated by simple logistic regression. This rodent consumed 23 plant species, mainly the leaves, resulting a low niche breadth. This species presented a greater consumption of leaves of Bauhinia cheilantha, influenced by low rainfall, and fallen flowers of Cenostigma pyramidale, influenced by high precipitation. This rodent showed plasticity in its diet and used different plant resources that provided its survival in semiarid.
