Stable Isotopes Analysis of Black Lion Tamarins Reveals Increasing Arthropod Consumption When Fruit Productivity Decreases in Forest Fragments.

Given the cryptic and elusive nature of prey consumption, quantifying its contribution to the diet of free-ranging primates using behavioral methods is challenging. In this context, the use of carbon and nitrogen-stable isotopes represents a promising alternative approach. Here, we used stable isotope analysis to estimate the proportion of arthropods and fruits in the diet of black lion tamarins (Leontopithecus chrysopygus), an endangered primate endemic to the Brazilian Atlantic Forest.

Performance of autonomous recorders to detect a cryptic and endangered primate species, the black lion-tamarin (Leontopithecus chrysopygus).

Information about species distribution is important for conservation but the monitoring of populations can demand a high sampling effort with traditional methods (e.g., line transects, sound playback) that are poorly efficient for cryptic primates, such as the black lion tamarin (Leontopithecus chrysopygus).

Correction to: Predation of treefrogs (Anura: Hylidae) with toxic skin secretions by the black lion tamarin (Leontopithecus chrysopygus, Callitrichinae).

In the original publication of the article, the scientific name of veined treefrog.

Predation of treefrogs (Anura: Hylidae) with toxic skin secretions by the black lion tamarin (Leontopithecus chrysopygus, Callitrichinae).

We report on the predation of a veined treefrog (Trachycephalus venulosus) and an ocellated treefrog (Itapotihyla langsdorffii), both species with noxious skin secretions, by black lion tamarins (Leontopithecus chrysopygus). The two predation events took place in Morro do Diabo State Park, an Atlantic Forest reserve in southeastern Brazil. The veined treefrog was removed from a tree hollow by an adult male, whereas the ocellated treefrog was caught on the ground after it jumped from the tree attempting to escape capture.

ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America.

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta.

ATLANTIC MAMMAL TRAITS: a data set of morphological traits of mammals in the Atlantic Forest of South America.

Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species.

Pelage Variation and Distribution of the Black Lion Tamarin, Leontopithecus chrysopygus.

The black lion tamarin, Leontopithecus chrysopygus, is endemic to the Atlantic Forest of the interior of the state of São Paulo in Brazil. Since the discovery of the species, authors have described variations in the pelage of L. chrysopygus, but the nature of this variation has remained unknown.
