Carnivora species present specialisations for carnivorous diet, although their dietary spectrum is variable: some are strictly carnivorous, others feed mostly on plants. Knowledge about Carnivora feeding habits and resource use patterns is the basis for understanding ecological dynamics, including their role in ecosystems, trophic interactions and conservation.We aimed to contribute to the identification and description of the trophic guild structure of Carnivora species throughout the Neotropical Region and explore the main drivers behind their structuring.We compiled Carnivora dietary studies and evaluated trophic guild formation through network analysis, diet dissimilarity and overlapping. We investigated whether there is spatial variation in diet parameters and the role of phylogeny in trophic guild structuring.We found dietary studies for 32 species from six Carnivora families. We observed two important biases: most studies focus on large‐bodied felids and canids and were predominantly conducted in South and South‐eastern regions of South America. Additionally, it has been noted that biomes such as the Amazon and Caatinga require further research on dietary studies.The network patterns evidenced that central items in carnivorans' diet are small mammals, plants, arthropods and crustaceans. Modularity suggests grouping generalists/opportunists, marine‐based, plant‐based and two mammal‐based diets. Most opportunistic and generalist species were found within the families Canidae and Procyonidae, while felids were strictly carnivorous.Dietary parameters reveal carnivorans tend to maintain niche breadth regardless of the ecoregion, possibly by substitution of items in their diet. Finally, we observed that phylogeny is an important driver of dietary patterns, indicating that evolutionary history explains part of the habits of carnivores. Our review provides insights to identify broad‐scale patterns and guidelines for new studies. [ABSTRACT FROM AUTHOR]
