The Pedra Branca Forest is in a highly urbanised region of the central portion of Rio de Janeiro City and comprises the largest urban forest in the world (> 12,000 ha). The local flora and fauna are protected by three conservation units and the Estação Biológica Fiocruz Mata Atlântica (EFMA), which comprises 462 hectares on the east side of the remnant. The local biodiversity is still little known compared to other Atlantic Forest remnants from the Rio de Janeiro State. Here, we provide results of a survey of medium- and large-sized terrestrial mammals from the EFMA. In addition, we analysed the distribution of this fauna along three habitat types defined as Peridomicile, Transitional Forest and Forest Core. Sampling was performed from 2017 to 2020 and comprised a camera-trap survey, interviews with residents and local workers and occasional records. Results include occurrence records for 16 autochthonous and one allochthonous (Callithrix sp.) wild mammals, which are distributed into 14 families and seven orders, in addition to the presence of free-ranging domestic dogs and cats. Four species are in some category of threat of extinction at national or global levels. Amongst them, Leontopithecus rosalia (first record for the Rio de Janeiro City in more than a century) and Leopardus guttulus are classified as Vulnerable by IUCN. Most wild native species were registered in the three habitat types, but with differences in the frequency of records. Our results indicate that the presence of domestic dogs and cats influenced the species composition in each area, with Nasua nasua, Dasyprocta leporina and Didelphis aurita less frequent in places where domestic dogs and cats are more frequent. This is the first systematic effort to understand the occurrence and distribution of mid- and large-sized mammals in the Pedra Branca Forest.

Three Atlantic Forest remnants—Pedra Branca, Tijuca and Gericinó-Mendanha—are present in Rio de Janeiro City. The Pedra Branca Forest is the largest remnant of urban forest in the world and is located in a highly urbanised region of the central portion of the City. This remnant is partially connected to the Tijuca Forest by small forest fragments separated by highways and both are isolated from the Gericinó-Mendanha Forest by a matrix of urban densification. The flora and fauna of Pedra Branca are protected by the Parque Estadual da Pedra Branca (PEPB; Pedra Branca State Park), Parque Natural Municipal da Prainha, Reserva Biológica de Guaratiba and the Estação Biológica Fiocruz Mata Atlântica (EFMA; Fiocruz Atlantic Forest Biological Station). Most of the territory is preserved by the PEPB, which comprises areas above 100 m a.s.l. (ca. 12,000 hectares). The EFMA is on the east side of the remnant, in an area under high human pressure, whose biological diversity, including mammals, is still poorly known compared to other localities in the Municipality and in the State of Rio de Janeiro—for example, Tijuca Forest (
The EFMA is adjacent to six communities with high social vulnerability and precarious sanitation conditions. These communities extend through the forest edge, putting domestic and wild animals, insect vectors and humans in potential contact, which constitutes a favourable environment for the circulation of zoonotic and non-zoonotic pathogens (
Studies with mammals in the Pedra Branca Forest that used systematised sampling were only conducted for the small-sized species, including bats, rodents and marsupials (
Individualised records of medium- and large-sized mammals from Fiocruz Atlantic Forest Biological Station, Rio de Janeiro, south-eastern Brazil, registered by camera trap, are available in Suppl. material
The study was carried out at the Estação Biológica Fiocruz Mata Atlântica (EFMA; central coordinates
The location of the Estação Biológica Fiocruz Mata Atlântica (EFMA) on the east side of Pedra Branca Forest (left, above), Rio de Janeiro; and the distribution of camera-traps at EFMA, in areas defined as Peridomicile (yellow), Transition Forest (light green) and Forest Core (dark green). Combinations of letters and numbers refer to camera identifications. See Table 1 for coordinates, period and effort at each point.
The areas used for the mammal survey are distributed along a gradient of anthropogenic intervention, where each area defined for sampling represents a type of habitat along this gradient: (i) Peridomicile, which consists of areas up to 100 m adjacent to the communities (ca. 30–35 m a.s.l.) and is characterised by the presence of backyards and orchards, with vegetation dominated by exotic species; (ii) Transitional Forest, which extends from the end of the peridomicile area to 100 m.a.s.l., with a prevalence of native plants, but with dense understorey and low canopy; and (iii) Forest Core, including all areas above 100 m a.s.l. and comprising preserved areas, without human constructions, with little human activities, more open understorey, high canopy and great presence of epiphytic plants, streams and rock formations on a sloping topography.
The species survey was conducted using three different methods: (i) sampling with camera-traps; (ii) interviews with residents who live around the EFMA; and (iii) occasional records made directly by researchers during field activities. Only mammals whose species-level identification can be performed, based on external morphology, were considered in the results. This procedure allowed the inclusion of all mammals with a body weight of > 1.0 kg (
For the camera trap survey, Trophy Cam trail cameras (Bushnell, Overland Parks, KS, USA) were distributed at 19 points along the areas defined as peridomicile, transitional forest and forest core (Table

The interviews to survey the species that occur in the region were conducted with residents, Fiocruz employees involved in the maintenance of EFMA trails and researchers who work with the local fauna and flora. Occasional records of mammals made by our staff or by other Fiocruz researchers were also considered.
Effort for the camera trap survey was calculated by multiplying the number of cameras installed by the number of days remaining active (unit: camera-days;
The homogeneity of multivariate dispersions was tested following
The conservation status of each species on a global and national level was derived respectively from the IUCN Red List of Threatened Species (version 2021.3) and the Red Book of Threatened Brazilian Fauna (
In addition to domestic dogs and cats, the camera trap survey, interviews and other sporadic records revealed the presence of 17 species of medium- and large-sized autochthonous (16 spp.) and allochthonous (Callithrix sp.) wild mammals, which are organised into 14 families and seven orders (Table

The sampling effort with camera-traps provided 1,189 records of 12 species of wild mammals and domestic dogs and cats. Eighteen species were recorded by interviews, of which nine were not recorded by camera traps (Bradypus variegatus, Cabassous tatouay, Dasypus septemcinctus, Dicotyles tajacu, Eira barbara, Euphractus sexcinctus, Galictis cuja, Leontopithecus rosalia and Sapajus nigritus). Amongst them, the following six were included in our list: B. variegatus, Leontopithecus rosalia, S. nigritus and T. tetradactyla, which were confirmed by direct observation; and C. tatouay and E. sexcinctus, whose occurrence is confirmed for Tijuca Forest—an Atlantic Forest remnant geographically close to EFMA. Although the occurrence of D. tajacu has been confirmed for the Mendanha Forest—another Atlantic Forest remnant geographically close to EFMA—we chose not to include it in our list due to the rarity of the species in the Municipality of Rio de Janeiro. Thus, the records of Eira barbara, Galictis cuja, Dicotyles tajacu and Dasypus septemcinctus obtained from interviews were considered dubious. Eight species were recorded by direct observation, none exclusively.
Of the 17 wild mammal species recorded, all are autochthonous, except Callithrix sp., which is a hybrid of Callithrix jacchus and Callithrix penicillata, widely distributed in the City of Rio de Janeiro. The record of Leontopithecus rosalia is the first of the current distribution of the species to the Municipality of Rio de Janeiro. Leontopithecus rosalia is coded as Endangered in the Red Book of Threatened Brazilian Fauna (
Considering only the results of camera-traps, the highest concentration of records occurred in the peridomicile (N = 519, 0.391/camera-days), followed by the forest core (N = 375, 0.472/camera-days) and transitional forest (N = 295, 0.525/camera-days; Table

In the peridomicile, the most frequent species were Cuniculus paca (N = 162, 0.122/camera-days), Didelphis aurita (N = 146, 0.110/camera-days) and Canis lupus familiaris (N = 122, 0.092/camera-days); in the transitional forest, were Didelphis aurita (N = 166, 0.295/camera-days), Dasyprocta leporina (N = 66 records, 0.117/camera-days) and Canis lupus familiaris (N = 21, 0.037/camera days); while in the forest core, the predominant species were Cuniculus paca (N = 111, 0.140/camera-days), Dasyprocta leporina (N = 97, 0.122/camera-days) and Didelphis aurita (N = 58, 0.073/camera-days; Table
Didelphis aurita showed the highest frequency of occurrence, found in 89% of the sampling points, followed by Canis lupus familiaris, with 63%, and Tamandua tetradactyla with 58%. The domestic dog was recorded at all peridomicile points, in addition to records in some transitional forest and forest core points. However, domestic cats, Felis catus and Sylvilagus tapetillus were only found in the peridomicile points. On the other hand, Leopardus guttulus and Nasua nasua were recorded only in the Transitional Forest and Forest Core. Cerdocyon thous was recorded in the Peridomicile and Transitional Forest (Table

Considering the three sampling areas (Peridomicile, Transitional Forest and Forest Core) as independent populations, we did not find significant differences between the averages of camera-day records for these areas (F = 0.238; p = 0.792; Fig.
The areas showed homogeneity of multivariate dispersion (F = 1.29, p = 0.29) and differed significantly in relation to the similarity of the records (F = 4.75, p < 0.001, Fig.
Dendrogram produced by cluster analysis (Ward method) from the similarity (Jaccard distance) between points in the peridomicile (yellow), transitional forest (light green) and forest core (dark green), considering the species richness of medium and large-sized mammals in the Estação Biológica Fiocruz Mata Atlântica, Rio de Janeiro.
Our data indicated the existence of three stable groups (mean bootstrapped Jaccard similarities > 0.85 and overall cluster instability < 0.06 for all three clusters). Peridomicile records clearly differentiate this area from the other two (i.e. Transitional Forest and Forest Core) as all sample points defined as Peridomicile were grouped into a single cluster (Fig.
About 60 spp. of mammals from different orders are known to occur in the region of the Pedra Branca Forest (
Despite differences in habitat structure and composition amongst the Peridomicile area, Transitional Forest and Forest Core, differences were not observed in the abundance of medium and large mammals amongst these areas in the EFMA. The survey focused mainly on the use of camera traps because they favour records of species that are difficult to detect through active search and because the method requires less effort when compared to active search or capture (
In surveys with camera-traps conducted in the mountainous region of Rio de Janeiro, which comprises the largest remnant of continuous Atlantic Forest in the State, more than 20 species of medium and large mammals were recorded, including some threatened, such as Puma yagouaroundi, Puma concolor, Dicotyles tajacu and Tayassu pecari (e.g.
Domestic dogs and cats, which showed high frequency of occurrence in the EFMA, also showed high frequency in Parque Nacional da Tijuca (
Domestic dogs and cats exert different types of pressure on local biodiversity. Amongst the 17 wild species recorded in the EFMA, there are predation records by dogs for eight species, competition records for six and pathogen transmission reports for two (
In relation to primates, it is also worth mentioning the record of the golden-lion-tamarin, Leontopithecus rosalia, in the EFMA and adjacent areas. One individual of this species was recorded by direct observation in 2017, living with a group of Callithrix. Subsequently, the species was also reported by residents and Fiocruz employees, who reported the presence of more than one individual, with at least one female and a juvenile. We have records of at least three individuals that co-exist with Callithrix in the surroundings of EFMA. The species is endemic to the southeast Atlantic Forest, originally occurring in coastal lowland forests of the States of Rio de Janeiro and southern Espírito Santo (
Peridomicile is a distinct area inside EFMA’s territory concerning medium- large-sized mammal communities, probably by the effects of the high level of anthropogenic disturbances. Habitat loss, introduction of exotic species and poaching are the main threats to mammals in the Pedra Branca Forest (
