“…However, due to the difficulty in identifying prey items to genus or species (Magezi 2013), most data were not included in category clustering. Thus, in order clustering, which includes Rodentia data, we argue that Leopardus pardalis occupies a more plausible place within small felids and rodent‐based species, such as Leopardus wiedii , Leopardus tigrinus and Puma yagouaroundi (Silva Pereira 2009, Magioli & Ferraz 2018).…”

“…Firstly, we underlined that the large cats, Puma concolor and Panthera onca were placed together. The especially high consumption of larger mammal prey and even other carnivores by these species is well known (Rueda et al 2013, Magioli & Ferraz 2018, 2021, Llanos & Travaini 2020). Some researchers relate this to the morphological capability of larger predators to feed on larger prey (Carbone et al 2007, Rueda et al 2013, Santos et al 2014, Perilli et al 2016).…”

“…Yet, we were still able to separate small cats, mostly from Leopardus genera: Leopardus colocolo (Molina, 1782), Leopardus geoffroyi (D'Orbigny & Gervais, 1844), Leopardus tigrinus (Schreber, 1775), Leopardus wiedii (Schinz, 1821) and Puma yagouaroundi (Saint‐Hilaire, 1803). It was clear that small cats remain together within the same trophic guild, especially due to rodents and small vertebrates' consumption (Silva Pereira et al 2011, Kasper et al 2016, Magioli & Ferraz 2018, Cruz et al 2021). The Neovison vison was placed within this same guild, due to rodents and lagomorph consumption.…”

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.

Mechanisms of coexistence in a diverse Neotropical mammalian carnivore community

Mammalian carnivore diversity within the Reserva Natural del Bosque Mbaracayú in eastern Paraguay is represented by five families (Canidae, Mephitidae, Mustelidae, Procyonidae, and Felidae) and includes large-bodied, apex predators, several omnivores, and numerous mesocarnivores. The competitive exclusion principle argues that sustained spatial and temporal coexistence of two or more species with identical ecological requirements is unsustainable. The Reserve is a mosaic of habitats that has become isolated due to extensive deforestation of the surrounding Upper Paraná Atlantic Forest. Nevertheless, it is remarkable in that 16 mammalian carnivore species are documented as coexisting within the Reserve. We sought to determine the extent to which this diverse community is mitigating competition through the partitioning of available niche space by assessing dietary ecology of mammalian carnivores present, including diet breadths and dietary overlap, and by examining spatial patterns within the reserve. Feces were collected from all 16 mammalian carnivore species from seven areas within the reserve and specific identifications were confirmed by molecular analyses. Diet breadth, B^, standardized diet breadth, B^A, and Pianka’s Index for dietary overlap, O^, were calculated. A Chi-square goodness-of-fit test was performed to test for randomness of samples associated with survey areas. Diet analyses indicated a spectrum from dietary generalists to specialists. Species segregated into six dietary guilds, defined as groups of species with O^ > 0.5. Four guilds included only one species each (Neotropical otter, crab-eating fox, jaguar, and puma). The low dietary overlap between jaguar and puma contrasts with studies conducted elsewhere. One guild consisted of four highly omnivorous species (maned wolf, Molina’s hog-nosed skunk, crab-eating raccoon, and South American coati). The sixth guild included eight species which mostly consumed small vertebrates, primarily mammals as well as birds and reptiles (bush dog, two mustelines, five small felids). The mustelines (tayra and lesser grison) had extremely high dietary overlap. Although they did not segregate spatially, they are known to occupy distinct niches in vertically stratified forests. The five small felids also showed extremely high dietary overlap. Three of them were found to segregate spatially within the Reserve and two did not, although one (jaguarundi) is known to segregate temporally, being more active diurnally. The exceptionally rich community of mammalian carnivore species at the Reserva Natural del Bosque Mbaracayú appeared to avoid unsustainable competition by a variety of mechanisms, some utilizing different food items, or, in the case of high dietary overlap, utilizing spatial or temporal resources differently.
