Between april 2005 and May 2006, according to the pressuposts of line transect methodology, census were carried to estimate abundance and population density of Callicebus nigrifrons Spix, 1823 (Pitheciidae) in Cantareira State Park, State of Sao Paulo, southeastern Brazil (23 degrees 23'42"S, 46 degrees 35'27"W). After 275.80 Km of census sampling...

We propose a method to analyse the 2009 outbreak in the region of Botucatu in the state of São Paulo (SP), Brazil, when 28 yellow fever (YF) cases were confirmed, including 11 deaths. At the time of the outbreak, the Secretary of Health of the State of São Paulo vaccinated one million people, causing the death of five individuals, an unprecedented...

The Black Lion Tamarin (BLT, Leontopithecus chrysopygus) is an endangered species, endemic to the State of Sao Paulo, Brazil. The conservation of the species depends on the effective management of the populations and forest conservation but also on the updated knowledge of its areas of occurrence. Here, we report the record of a new site of BLT occ...

Emerging infectious diseases were cited as a cause of population decline of wild nonhuman primates (NHPs) by A. Estrada and collaborators in their review “Impending extinction crisis of the world’s primates” (Science Advances, 18 January, e1600946). Concurrent with the publication of this review, an epidemic of jungle yellow fever (YF) in the Atlan...

Amblyomma is an important tick genus for animal and human health, with some species being the vectors of zoonotic pathogens, such as Rickettsia rickettsii, in the Neotropical region. Knowing their hosts may help to understand the distribution of these agents and decrease the occurrence of clinical cases. Primates are intelligent and adaptable anima...

Landscape connectivity is important for a wide range of ecological processes, including to disease spread, once it describes the degree to which landscapes facilitate or impede vector and hosts dispersion. Understanding connectivity is extremely important to identify where pathogens can move, and at what speed, allowing the organization of vaccinat...

Human activities are changing landscape structure and function globally, affecting wildlife space use, and ultimately increasing human-wildlife conflicts and zoonotic disease spread. Capybaras (Hydrochoerus hydrochaeris) are linked to conflicts in human-modified landscapes (e.g. crop damage, vehicle collision), as well as the spread and amplificati...

Cantareira State Park (CSP) is located in the Metropolitan Region of São Paulo, one of the most densely populated areas on the planet. Recently, a yellow-fever epidemic practically annihilated the howler monkey population in this park, and human infections were reported in the vicinity. As simian and human plasmodia also circulate in CSP, the prese...

This species is listed as Endangered based on a suspected population reduction of >50% over the past three generations (2000-2018) due to habitat loss (>43%), competition and hybridization with invasive species, and occasional live capture for the pet trade.

Human activities are changing landscape structure and function globally, affecting wildlife space use, and ultimately increasing human-wildlife conflicts and zoonotic disease spread. Capybara ( Hydrochoerus hydrochaeris ) is a conflict species that has been implicated in the spread and amplification of the most lethal tick-borne disease in the worl...

Background Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, has been associated with the transmission by the tick Amblyomma sculptum, and one of its main hosts, the capybara (Hydrochoerus hydrochaeris). Methods During 2015–2019, we captured capybaras and ticks in seven highly anthropic areas of São Paulo state (three e...

Chiropotes satanas ocorre no leste da Amazônia no arco do desmatamento, onde sofre pressão de caça. Suspeita-se que houve uma redução de pelo menos 80% da população original nas últimas três gerações ou 30 anos. O desmatamento e fragmentação do seu habitat em toda sua extensão de ocorrência são as principais ameaças. A espécie necessita de áreas de...

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...

The buffy-tufted-ear marmoset (Callithrix aurita) is a small primate endemic to the montane regions of the southeastern Atlantic Forest in Brazil. The species was formerly listed as “Vulnerable” (VU) on the Brazilian Official National List of Threatened Fauna Species, but in December 2014 it was re-classified as “Endangered” (EN) as a result of hab...

The liver fluke Fasciola hepatica (Trematoda: Fasciolidae) causes fascioliasis, which affects mostly domestic ruminants and humans worldwide. This parasite has an Old World origin and was introduced into the New World by European colonizers. Capybara (Hydrochoerus hydrochaeris) is the largest living rodent species, with adults weighing over 60 kg....

Polyspecific or mixed-species associations, where two or more species come together to forage and travel as a unit, have been reported in many primate species. These associations appear to offer a number of benefits to the species involved including increased foraging efficiency and decreased risk of predation. While several researchers have sugges...

Pitheciids are known for their frugivorous diets, but there has been no broad-scale comparison of fruit genera used by these primates that range across five geographic regions in South America. We compiled 31 fruit lists from data collected from 18 species (three Cacajao, six Callicebus, five Chiropotes, and four Pithecia) at 26 study sites in six...

The neotropical primate family Pitheciidae consists of four genera Cacajao (uacaris), Callicebus (titis), Chiropotes (bearded sakis) and Pithecia (sakis), whose 40+ species display a range of sizes, social organisations, ecologies and habitats. Few are well known and the future survival of many is threatened, yet pitheciines have been little studie...

The common English name for the genus Chiropotes is currently bearded saki. We propose the use of "cuxiú" as the common name for Chiropotes species, arguing that this term not only has deeper cultural and historical roots, but would mesh with the common name currently in use over the vast majority of the genus range. Cuxiú (pronounced "coosh-e- oo"...

Neotropical monkeys of the genera Cacajao, Chiropotes, and Pithecia (Pitheciidae) are considered to be highly arboreal, spending most of their time feeding and traveling in the upper canopy. Until now, the use of terrestrial substrates has not been analyzed in detail in this group. Here, we review the frequency of terrestrial use among pitheciin ta...

We studied the potential contribution of frugivorous bats to the reestablishment of vegetational diversity in a restored area. We analysed the diets of the bat species and the differences between them in the consumption of fruits of autochtonous and allochthonous species. Planted (autochtonous) species were the basis of diets, especially Solanum ma...

Martius, mais conhecida como palmito Juçara, encontra-se atualmente sob o risco de extinção (Governo do Estado de São Paulo, 2003), apesar de ser exigido um plano de manejo sustentável para a sua exploração, os casos de extração ilegal de vêm aumentando (Galetti & Fernandez, 1998). O palmito ocorre no estrato médio da Floresta Ombrófila Densa, desd...

Tufted capuchins (Cebus apella) have the widest geographic range of any platyrrhine species, and they are also the most flexible, both behaviourally and ecologically. Capuchin diets are highly diverse and encompass a wide variety of vegetable and animal material, including non‐reproductive plant parts, arthropods and vertebrates [Terborgh, 1...

An adult Harpy Eagle (Harpia har-pyja) attacked and killed an infant collared peccary (Pecari tajacu) at a site in eastern Amazonia. The ea-gle appeared to have been prevented from removing its prey immediately by surviving members of the pec-cary herd. Circumstantial evidence suggests that a set of specific factors, including the abundance of pecc...

Predation of Hyla nahdereri (Anura: Hylidae) by Cyclarhis gujanensis (Aves: Vireonidae) in Santa Catarina state, Brazil. During a field trip in the region of Rio dos Cedros, in the interior of Santa Catarina state, Brazil, we observed the predatory behavior of a pitiguari, Cyclarhis gujanensis. The pitiguari captured and ingested a small tree-frog...
