Filogenia e dieta de canídeos da subtribo Cerdocyonina

Abstract

There are a total of 10 extant canids from the Cerdocyonina subtribe, all of which are endemic to South America, living in a diversity of habitats from the Cerrado to the mountains. This study sought to identify a possible correlation between diet and phylogeny in these canids. This study analyzed 34 articles about the diet of 8 South American canids. These articles used various methods for data collection, fecal and stomach samples and direct observation, the most common was fecal analysis. Diet similarity was measured using BrayCurts index. Information was collected on 292 food items by genus and/or species. Two dendrograms were created, one that analyzed each genus/species of food item, and the second that analyzed food items by groups (mammals, birds, reptiles, amphibians, fish, invertebrates, plants). A weak correlation between diet and phylogeny was found for south American canids.
