The factors that promote ecological separation among closely related sympatric carnivores in tropical forests are poorly understood due to a paucity of field studies. Here, we report on community-wide food resource utilization patterns among eight co-existing carnivores in the Dzanga-Sangha Reserve, Central African Republic, based on a collection of 666 scats that were identified using a combination of methods, including thin-layer chromatography. Members of the assemblage took advantage of the… 
Trophic ecology of sympatric small cats in the Brazilian Pampa
TLDR
Despite their habitat and diet similarities, these four species explore distinct microhabitats by foraging different prey groups, what favor them to live in sympatry.
Diversity of small carnivores in Pendjari biosphere reserve, Benin
TLDR
The results suggested that Felidae were more vulnerable to anthropogenic activities than other carnivores, and these species and jackal could be used as indicator species in Pendjari ecosystem.
Trophic relationships of sympatric small carnivores in fragmented landscapes of southern Brazil: niche overlap and potential for competition
TLDR
The food niche breadth was relatively narrow, demonstrating that even generalist species, such as the crab-eating raccoon, used food resources rather unequally, and Conepatus chinga was unique in exploiting arthropods and insect larvae as basic dietary items.
Co-occurrence patterns in independently evolved groups of Mediterranean insectivorous vertebrates (lizards and shrews)
TLDR
The data indicated that the assemblage of shrews and lizards was likely regulated essentially by local climate and not by synecological (interspecific competition) dynamics, thus demonstrating that interspecific competition was not the main force driving these assemblages of species.
Competition and specialization in an African forest carnivore community
TLDR
It is found that community assembly and coexistence in this ecosystem are primarily driven by more complex processes, which suggests that preserving the observed community assemblage will require the maintenance of a large variety of habitats, with a particular focus on those required by the more specialized carnivores.
Niche Partitioning among Mesocarnivores in a Brazilian Wetland
TLDR
It is suggested that temporal segregation of carnivores was more important than spatial segregation, notably between the generalist coati, crab-eating fox and Crab-eating raccoon, and the more specialized ocelot.
Surveys of mammal communities in a system of five forest reserves suggest an ongoing biotic homogenization process for the Niger Delta (Nigeria)
TLDR
Overall, a biotic homogenization process for the mammal communities of the five forest reserves was observed, likely as an outcome of the high deforestation of the last 50 years.
Niche Partitioning amongMesocarnivores in a BrazilianWetland
We investigated the home range size, habitat selection, as well as the spatial and activity overlap, of four mid-sized carnivore species in the Central Pantanal, Mato Grosso do Sul, Brazil. From
Intraguild dynamics of understudied carnivores in a human‐altered landscape
TLDR
It is found that African civets and bushy‐tailed mongooses avoid each other spatially and temporally, which contributes to scant ecological knowledge of these mesocarnivores and adds to understanding of community dynamics in human‐altered ecosystems.
Food Habits of Jaguar and Puma in a Protected Area and Adjacent Fragmented Landscape of Northeastern Mexico
TLDR
The diet of both felids included almost exclusively wild species, suggesting the presence of a good prey base that allows the coexistence of jaguars and pumas in a protected area surrounded by a fragmented landscape in northeastern Mexico.

The carnivore community in a dry tropical forest mosaic in Huai Kha Khaeng Wildlife Sanctuary, Thailand
TLDR
Twenty-one carnivore species of five families were found to be feeding on at least 34 mammal species, as well as birds, lizards, snakes, crabs, fish, insects, and fruits, in an area of dry tropical forest in Huai Kha Khaeng Wildlife Sanctuary, Thailand.
Patterns of Tropical Vertebrate Frugivore Diversity
The production of fleshy fruits by angiosperms and their consumption by a diverse array of vertebrates is a quintessential tropical phenomenon. Although fleshy fruits are produced by many kinds of
Temporal variation of predation on rodents and shrews by small African forest carnivores
TLDR
Analysis of small carnivore scats collected over a two-year period in a seasonal forest in the south-western Central African Republic yielded the remains of 732 shrews, rodents, and bats comprising at least 34 species, suggesting mongooses and perhaps other small carnivores were foraging in micro-habitats characterized by higher-than-average vegetation understorey thickness.
Dietary separation of sympatric carnivores identified by molecular analysis of scats
TLDR
Analysis of diets of four sympatric carnivores in the flooding savannas of western Venezuela by analysing predator DNA and prey remains in faeces shows that puma and jaguar scats overlap in size, as do those of puma, ocelot and fox.
Food niche separation between four sympatric Namib Desert carnivores
The diet of four sympatric carnivore species was established by analyzing scats collected during 1978-1980, a period of increasing drought in the Namib Desert. Termites were especially important in
Comparative ecology of two African forest mongooses, Herpestes naso and Atilax paludinosus
TLDR
It is suggested that the higher degree of habitat specificity exhibited by Atilax in the study area compared with other parts of its range was a result of the absence of otters from the smaller tributaries of the Dzanga-Sangha forest or perhaps to the social dominance of Herpestes naso.
Food habits of some neotropical carnivores in Venezuela (Mammalia, Carnivora)
— Food habits of seven neotropical carnivores were determined by analysis of stomach contents. The species include the kinkajou (Potos flavus, N = 20), raccoon (Procyon cancrivorus, N = 9), coati
Small nocturnal carnivores: ecological studies in the Serengeti
TLDR
Comparative studies of activity patterns, microhabitat preferences, foraging behaviour and diet indicate surprisingly broad overlap among small nocturnal carnivores along the niche dimensions investigated.
Food habits of three carnivore species (Viverricula indica, Herpestes urva, and Melogale moschata) in Fushan Forest, northern Taiwan
TLDR
The food habits and degrees of dietary overlap of lesser oriental civet, crab-eating mongoose, and ferret badger inhabiting the Fushan Forest, northern Taiwan, were studied using faecal analysis between February 1993 and June 1994.
FEEDING SPECIALIZATION OF THE EUROPEAN BADGER MELES MELES IN SCOTLAND
TLDR
It is suggested that badgers change their foraging effort to compensate for fluctuations in earthworm availability, consuming a range of secondary foods.
