Identifying the factors that determine local extinction of populations is crucial to ensure species conservation. Forest-dwelling primates are especially vulnerable to habitat fragmentation, although few studies have provided systematic evidence of local extinctions. Over an 11-year period, approximately 100 remnant populations of the endangered Coimbra Filho’s titi monkey (Callicebus coimbrai) have been found within the geographic range of the species in Bahia and Sergipe, Northeast Brazil… 
Distribution and conservation status of Boutourlini’s blue monkey (Cercopithecus mitis boutourlinii), a Vulnerable subspecies endemic to western Ethiopia
A complete reassessment of the distribution and conservation status of Boutourlini’s blue monkey will require further surveys across the remaining approximately 60% of its potential range.
Structure and Composition of Atlantic Forest Fragments Inhabited by Callicebus coimbrai in Northeastern Brazil: Subsidies for Landscape Management Strategies
Characterizing the habitat structure, identifying the functionality of tree species is an important strategy to assist in management programs. This study aimed to characterize the habitat’s
Viability meets suitability: distribution of the extinction risk of an imperiled titi monkey (Callicebus barbarabrownae) under multiple threats
Ongoing environmental changes may reduce the population size and geographic distribution of many ecologically sensitive species. Predicting where populations will (or will not) be likely to resist
Can a Non-Native Primate Be a Potential Seed Disperser? A Case Study on Saimiri sciureus in Pernambuco State, Brazil
Evidence is provided that non-native S. sciureus may be acting as a potential seed disperser of native plants in the Atlantic forest fragment, contributing to the ecological role of native frugivores, and potentially contribute to the regeneration process of the highly degraded study site.
Working Together Towards One Goal: Results of the First Primate Census in Western Ecuador
Effective conservation strategies need to be created based on accurate and updated data on the distribution and conservation status of the species of concern. Not surprisingly, the most diverse
Primates in peril: the significance of Brazil, Madagascar, Indonesia and the Democratic Republic of the Congo for global primate conservation
The anthropogenic pressures each country is facing that place their primate populations at risk are examined and the key challenges faced by the four countries to avert primate extinctions now and in the future are listed.
Range extension for Wedge-billed Woodcreeper Glyphorynchus spirurus cuneatus in north-east Brazil
This record of G. spirurus represents an extension of the species’ range in eastern Brazil, within a matrix of eucalypt and bamboo plantations, and pasture at a private reserve in Sergipe, Brazil.


Preliminary Evaluation of the Conservation Status of Callicebus coimbrai Kobayashi & Langguth, 1999 in the Brazilian State of Sergipe
Abstract Endemic to the Atlantic forest of the Brazilian states of Sergipe and Bahia, Callicebus coimbrai survives in a highly fragmented landscape characterized by small remnants of forest in a
Dynamics of Primate Communities along the Santarém-Cuiabá Highway in South-Central Brazilian Amazonia
All Neotropical primates (Platyrrhini) are highly specialized for an arboreal way of life (Hershkovitz, 1977) and rarely, if ever, come to the ground under natural conditions, despite the fact that
On the occurrence of Cebus flavius (Schreber 1774) in the Caatinga, and the use of semi-arid environments by Cebus species in the Brazilian state of Rio Grande do Norte
Four Cebus populations are reported on, including the first occurrence of C. flavius in the Caatinga, and an expansion of the northwestern limits of distribution for the species.
Coping with Forest Fragmentation: The Primates of Kibale National Park, Uganda
No species characteristics—home range, body size, group size, or degree of frugivory—predicted the ability of species to live in patches, and the lack of strong predictive variables as well as differences between other studies of fragmentation caution against making generalizations about primate responses to fragmentation.
Effects of Forest Fragmentation on the Abundance of Colobus angolensis palliatus in Kenya’s Coastal Forests
We documented the occurrence and abundance patterns of Angola black-and-white colobus (Colobus angolensis palliatus) in 46 coastal forest fragments ranging from 1 ha to >1400 ha in the Kwale
Dense understory and absence of capuchin monkeys (Sapajus xanthosternos) predict higher density of common marmosets (Callithrix jacchus) in the Brazilian Northeast
The analysis indicated that the marmosets prefer forests with denser understory, whether or not they are secondary habitats, and the negative effect of the presence of capuchins may be related to predation pressure.
