“…In the diet of the crab-eating fox, fruits are an important resource as cited by many investigators throughout the species' range, although there is a wide variation in the consumption rate (Facure et al 2003, Rocha et al 2004, Pedó et al 2006). This species is an opportunistic predator with a diet that varies according to availability, seasonality, and social aspects (Courtney and Maffei 2004).…”

Trophic relationships of sympatric small carnivores in fragmented landscapes of southern Brazil: niche overlap and potential for competition

et al. 2016

Between 2000 and 2010, digestive tracts collected from carnivore carcasses found in southern Brazil were analyzed to determine the frequency and proportion of items constituting the diets of each species. Material was collected and analyzed from 194 animals of 10 species: Cerdocyon thous, Lycalopex gymnocercus (Canidae), Procyon cancrivorus (Procyonidae), Galictis cuja (Mustelidae), Conepatus chinga (Mephitidae), Leopardus colocolo, Leopardus geoffroyi, Leopardus guttulus, Leopardus wiedii, and Puma yagouaroundi (Felidae). Most of these species are sympatric, which makes them potential competitors when sharing, to a greater or lesser degree, the same resources. The food niche breadth was relatively narrow, demonstrating that even generalist species, such as the crab-eating raccoon, used food resources rather unequally. An extensive overlap ( > 90%) in food niches was found among the cat species, the grison, and the Pampas fox, which had diets based on rodents. Crab-eating raccoons occupied a different food niche, based on aquatic or semiaquatic prey and fruits. Conepatus chinga was unique in exploiting arthropods and insect larvae as basic dietary items.

“…Isso também foi visto por outros autores em outras localidades (PASCHOAL & GALETTI 1995, BORDIGNON & MONTEIRO-FILHO 1999, o que corrobora a importância desta palmeira na dieta dos serelepes. Além disso, o jerivá é uma espécie importante não somente para os serelepes mas também para outros mamíferos frugívoros (PASSOS 1999), como por exemplo Alouatta guariba (Humboldt, 1812) (AGUIAR et al 2003, MIRANDA & PASSOS 2004, Leontopithecus chrysopygus (Mikan, 1823) (PASSOS 1999) e Cerdocyon thous (Linnaeus, 1758) (FACURE & MONTEIRO-FILHO 1996, ROCHA et al 2004.…”

Este estudo foi realizado entre fevereiro de 2002 e janeiro de 2003, em um remanescente de Floresta com Araucária, localizado no Distrito do Bugre, Município de Balsa Nova, Paraná, Brasil. O objetivo foi conhecer as espécies utilizadas na alimentação por Sciurus ingrami Thomas, 1901 no decorrer de um ano. Foram registradas dez (N = 10) espécies na dieta dos serelepes, pertencentes a sete famílias botânicas. Os serelepes predaram sementes de três espécies e se alimentaram de três espécies exóticas, mostrando adaptabilidade a ambientes alterados.

Crab-eating fox, Cerdocyon thous, is a habitat generalist species relatively common throughout its range inhabiting most environments owing to its low habitat requirements. Because no information is available for anthropogenic habitats, this study aimed to describe the species occurrence in a highly fragmented and heterogeneous landscape in southeastern Brazil. C. thous was surveyed in 95 study sites in four main land covers (native forest, eucalyptus forest, sugar cane and pasture) from April to September 2006. Presence records (ns28) and landscape variables (land cover, heterogeneity, stream and forest fragment distance, elevation and slope) were used for modeling in Maxent. The bootstrapping method was used for sampling 70% of the dataset for training and 30% for testing models. The species was equally distributed in all types of land cover, although it was more frequent in the sugar cane areas and more associated with forest fragments and heterogeneous habitats. The potential distribution model predicted forest patches and its surroundings as highly suitable for the species. It also predicted part of the sugar cane matrix as highly suitable, probably related to prey availability. Results suggested that the anthropogenic landscape studied encompasses many suitable habitats for species occurrence, resulting in the necessity to assess its potential role in vertebrate communities.
