Article
Full-text available
Fruit pulp is an easily handled energy source for many frugivorous species but generally has little protein. Accordingly, ripe-fruit specialist primate species with diets dominated by fruit pulp risk protein deficiency. While some species use leaf and flower buds, young leaves, and arthropods as an alternative protein supplement, highly frugivorous...

The main factors influencing feeding competition among members of diurnal primate groups are the distribution, availability, and quality of food resources. Socioecological models predict that temporal availability of preferred resources, such as fruit, can influence intragroup feeding competition, which is expected to affect rates of agonism and in...

The maned wolf (Chrysocyon brachyurus; Carnivora, Canidae) is the South America's largest canid, typically occurring in open areas of Cerrado, Chaco and Pampa. Its geographical distribution is historically limited to the north by the Amazon forest, and to the northeast by the Caatinga and Atlantic Forest biomes. However, recent studies have reporte...

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...

Predation risk is important in influencing animal behaviour. We investigated how the choice of nocturnal sleeping and diurnal resting sites by two species of primates was influenced by the most likely forms of attack (diurnal raptors and nocturnal felids). We recorded vertical and horizontal patterns of occupancy for 47 sleeping and 31 resting site...

Ecological niche models (ENMs) are widely used tools for predicting species geographic distribution as a function of environmental variables. The inclusion of biotic factors in the predictor suite can significantly increase the predictive power of such models, leading to a model closer to the realized niche for the species under investigation. In t...

O lobo-guará (Chrysocyon brachyurus; Carnivora, Canidae) é o maior canídeo da América do Sul, ocorrendo tipicamente em áreas abertas de Cerrado, Chaco e Pampa. Sua distribuição geográfica é historicamente limitada ao norte pelas florestas do bioma Amazônico, e à nordeste pelos biomas da Caatinga e Mata Atlântica. No entanto, estudos recentes têm re...

Although relatively common among omnivorous primates, anurophagy is still poorly documented in frugivorous species. Here we report the predation of a giant gladiator treefrog (Boana boans) by a large arboreal frugivore, the gray woolly monkey (Lagothrix lagotricha cana). The predation event occurred in a stretch of riparian forest located in a frag...

The post-fledging period is of paramount importance for raptors, since this is when a juvenile develops its hunting skills and gains the abilities required in adulthood and independence through dispersal. Little is known however, about this stage in the lives of raptors such as harpy eagles, Harpia harpyja. Between March 2016 and July 2017, we reco...

Deviations from sex-biased dispersal patterns of primate species have often been attributed to local demography, particularly in cases of dispersal by males in what are typically male philopatric societies. Here, we evaluate the demographic conditions associated with novel observations of intergroup movements by two male northern muriquis, Brachyte...

Project
To provide key information to base conservation actions for the endangered Black-faced black spider monkey (Ateles chamek) in the Amazon. Specifically, we aim: (i) to update the information on the species distribution, specifically the extent of occurrence (EOO) and area of occupancy (AOO); (ii) to evaluate how environmental filters and biotic interactions affect species distribution and how they act to arrange the habitat suitability for the species; (iii) to assess the conservation status of the species; and (iv) to indicate priority areas for the conservation of species.
Project
The main objectives of the project are to: (i) provide the first habitat-based modeling of the geographic distribution of L. cana over its entire range using Ecological Niche Models, and produce a framework for the conservation of this species describing the status of the areas with highest species-specific habitat suitability and which parts of these areas are under legal protection; (ii) quantify the current and future habitat loss for L. cana in these areas; and (iii) apply this to conservation planning and management in the region via information generated for the National Action Plan for the Conservation of Amazonian Primates, integration of local communities into conservation activities and fostering public and scientific awareness.
Project
The main objective of this project is to evaluate the influence of fruit availability and consumption on the agonistic behavior and interindividual distance in gray woolly monkeys (Lagothrix cana) in southwestern Brazilian Amazonia. Specifically, we are testing: (i) whether overall fruit availability predicts the degree of frugivory of the woolly monkeys; (ii) if their degree of frugivory influence the rate of agonistic interactions and the spatial distances among group members; and (iii) if the rate of agonistic interactions and intragroup spacing distances are correlated.
