Our aim is to provide an update about what we know and do not know about primates in Brazilian Amazonia, as well as to highlight key threats and to identify research and conservation priorities. Here, we provide a history of primatology in the Brazilian Amazon and a literature review of primate research locations there between 1968 and 2018. Most o...
The current biodiversity crisis has generated a growing demand for information on the status and trends of biodiversity, especially in mega diverse regions such as the tropics, where comprehensive data is lacking. In view of this, the Brazilian government developed the Brazilian in situ monitoring program of Federal Protected Areas – Programa Monit...
O principal objetivo da oficina foi avaliar se o manejo ex situ é uma ferramenta de conservação adequada para as espécies selecionadas (listadas abaixo) e definir qual(is) papel(is) o manejo ex situ pode desempenhar na estratégia geral de conservação da espécie. No caso das espécies que já possuem um programa ex situ estabelecido, como as incluídas...
Brazilian primates differ regarding landscape characteristics within their ranges (e.g. habitat availability) and life‐history traits (e.g. body size). These landscape and life history attributes may be related to extinction risk. Here, we verified how such attributes correlate with primate threat categories. We considered 124 Brazilian primates ba...
Terrestrial mammals face a severe crisis of habitat loss worldwide. Therefore, assessing information on habitat loss throughout different time periods is crucial for assessing species’ conservation statuses based on the IUCN Red List system. To support the national extinction risk assessment in Brazil (2016–2022), we developed a script that uses th...
In 2019, a canopy bridge was built connecting two fragments of the Atlantic Forest separated by the Pacatuba unpaved road within the Pacatuba-Gargaú Corridor. This bridge was built as part of the Brazilian National Action Plan for the Conservation of Northeastern Primates ( Plano de Ação Nacional para Conservação dos Primatas do Nordeste – PAN PRIN...
Brazil is known as a high biodiversity country, but at the same time, it has an extensive road network that threatens its wildlife and ecosystems. The impacts of roads and railways on vertebrates have been documented extensively, and the discussion concerning the implementation of mitigation measures for terrestrial wildlife has increased in the la...
Assessing the conservation status of species is essential for implementing appropriate conservation measures. A lack of evidence of threats, rather than showing an absence of impacts, could reflect a lack of studies on how human activities could result in species population declines. The range of Prince Bernhard's titi monkey Plecturocebus bernhard...
Fifty years of deforestation in the Arc of Deforestation have put at risk species survival, ecosystem services and the stability of biogeochemical cycles in Amazonia, with global repercussions. In response, we need to understand the diversity, distribution and abundance of flagship species groups, such as primates, which can serve as umbrella speci...

Alouatta guariba is endemic to the Atlantic
Forest in eastern Brazil and northeastern
Argentina. In the south, its range is limited by the
Camaquã river basin in the state of Rio Grande
do Sul (Printes et al. 2001) and, in the past, to
the north by the Rio Paraguaçu in the state of
Bahia (Gregorin 2006).
Plecturocebus vieirai is endemic from the top global deforestation frontier, the Amazonian arc of deforestation, in the States of Mato Grosso and Pará. Based on new occurrence data, and models of species occurrence and of future deforestation in Amazonia, this species already lost 56% of its area of habitat only 14% of the species area of habitat w...

The red-handed-howler-monkey (Alouatta belzebul) is vulnerable to extinction mainly due to habitat loss and fragmentation, as well as hunting pressure. In its Atlantic Forest range, small populations inhabit 31 sparse fragments in a landscape dominated by a matrix of sugar cane plantations, pastures and urban areas. The aim of the present study was...
In 2011, a distinct but unnamed form of titi, Plecturocebus, was rediscovered in the Chapada dos Parecis, a plateau in the southern extreme of the Brazilian state of Rondônia. Here we describe it as a new species based on an analysis of morphological and molecular traits. It can be distinguished from all other species of the genus Plecturocebus by...
Howlers are highly susceptible to yellow fever, and two recent outbreaks have severely affected their numbers.
Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. Mortality due to roads (hereafter road-kill) can affect the dynamic of populations of many species and can, therefore, increase the risk of local decline or extinction. This is especially true in Brazil, where plans for road network upgrading and expansio...
Titi monkeys comprise the most diverse species group of Neotropical primates, with 34 currently recognized. Some are now threatened by deforestation for agriculture, and by forest fragmentation and major infrastructure projects. The identification and mapping of the Plecturocebus species ranges in the Amazon in particular has become a strategic iss...
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 specie...
