ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group composition, population density, and diet of 14 groups at two field sites in southeastern Peru. All sampled groups were found in secondary tropical rainforest, often dominated by native bamboo species. Half of the observed sleeping sites were in bamboo stands, though groups also emerged from cane thickets and lianas. This contrasts with other Aotus studies which have found groups living in tree cavities... |

Given their great variability, microsatellites or STRs became the most commonly used genetic markers over the last 15 years. The analysis of these markers requires minimum quantities of DNA, allowing the use of non invasive samples, such as feces or hair. We amplified the microsatellite Ap74 in blood and hair samples in order to analyze the levels of genomic conservation among a wide range of primates including: Lemur catta, Alouatta caraya, Ateles belzebuth, Ateles chamek, Pan troglodytes, Papio sp., and Homo sapiens. In all cases we obtained amplification products that exhibited similar size both in monkeys and human (oscillating between 126 and 176 bp), except in the lemur where the detected fragment presented a size of approximately 1000 bp. The... |

En el año 2000 se presentó lo que se dio en llamar nuestro libro de la vida, el primer borrador del genoma humano. Aquello generó grandes expectativas por sus potenciales en beneficio de las ciencias biológicas. ¿Qué ha sucedido diez años después? Se conoce el número de genes que forman parte de nuestro genoma y se determinó la función de algunos de ellos. Se conocen las secuencias de tres genomas completos de mamíferos, Mus musculus, Pan troglodytes y Sus scrofa y genomas completos o borradores de otros numerosos eucariota (otros animales, plantas, hongos y protistas) y procariota (Archea y Bacterias), ver: http://ncbi.nlm.nih.gov/genomes. Sin embargo, el estudio del genoma no se limita a la mera descripción de las secuencias que lo componen. Las... |

ABSTRACT Plecturocebus ornatus is an endemic vulnerable species due to its population decline and its restricted range within the Eastern Plains of Colombia. This region is affected by deforestation as a result of legal and illegal economic activities. The aim of this work was to analyze the presence and abundance of P. ornatus during a period of urban and livestock production expansion (1986-2019) in Villavicencio, Colombia. This municipality is the most affected by land-use changes associated with regional economic development and represents 3.4 % of P. ornatus distribution's area. The analysis was performed using satellite images Landsat 4 and 8, with V-Late in ArcGIS 10.5 to describe landscape structure, and P. ornatus occurrence records, obtained... |

Inferences about the diet of Miocene platyrrhine monkeys have relied upon the morphology of the molar teeth, specifically the crests on the molars. Using a library of Micro-CT images of a broad comparative sample of living platyrrhines (callitrichines, cebines, pitheciids and atelids), late early Miocene Homunculus, and the early Miocene Tremacebus and Dolichocebus, we extend these inferences by examining the surface areas of the tooth roots, anchor points for the periodontal ligaments. From muscle scars on the skull, we estimate the mechanical leverage of the chewing muscles at bite points from the canine to the last molar. Extant platyrrhines that gouge bark to obtain exudates do not have especially large canine roots or anterior premolar roots compared... |

Long-distance calls are widespread among primates. Several studies concentrate on such calls in just one or in few species, while few studies have treated more general trends within the order. The common features that usually characterize these vocalizations are related to long-distance propagation of sounds. The proposed functions of primate long-distance calls can be divided into extragroup and intragroup ones. Extragroup functions relate to mate defense, mate attraction or resource defense, while intragroup functions involve group coordination or alarm. Among Neotropical primates, several species perform long-distance calls that seem more related to intragroup coordination, markedly in atelines. Callitrichids present long-distance calls that are... |

ABSTRACT The wild cycle of rabies constitutes a serious challenge to epidemiological surveillance for disease control in domestic, companion or production animals, and in humans. The understanding of rabies virus circulation in the natural environment is increasingly important due to the constancy of natural reservoirs of the disease and the presence of potential vectors of the infection to humans and domestic animals. Aiming to evaluate the occurrence of rabies in the State of Sergipe a total of 935 hematophagous bats (Desmodus rotundus), 46 wild dogs (Cerdocyon thous) and 24 primates (Callithrix spp.) were analyzed from 1987 to 2014, of which 1 bat, 17 crab-eating foxes and no primates were positive. Due to the lack of positive results in hematophagous... |

ABSTRACT The common marmoset is an important Neotropical primate for biomedical research. With the intention of providing pelvimetric values that allow the selection of animals with better characteristics for reproduction, we studied the X-ray of the pelvis, in ventro-dorsal projection of 12 adult animals, six males and six females, belonging to the National Center of Primates - CENP. The measurements were made to right diagonal diameters (RDD), left diagonal diameter (LDD), bi-iliac middle diameter (BIMD), bi-iliac upper diameter (BIUD), bi-iliac lower diameter (BILD), sacrum-pubic diameter (SPD), and the input area of the pelvis (IAP), which were compared in relation to sex and bodily correlated with the biometrics. The results of the means and standard... |

Abstract The common marmoset (Callithrix jacchus) are small primates belonging to the family Cebidae, subfamily Callitrichinae and are the most well-known and common in adaptation to captivity. The scarcity of data in the literature on the anatomy of these marmosets and wild animals hinders the application of appropriate anesthetic and surgical procedures and therapeutics. In order to understand the anatomic variations in the lobation and bronchopulmonary segmentation the lungs were dissected from nine adult common marmoset (Callithrix jacchus) corpses, five males and four females. In the marmosets, the right lung presented cranial lobe, middle lobe, caudal lobe and accessory lobe while the left lung presented cranial and caudal lobes. The fissures were... |

The effects of habitat fragmentation and deforestation are exacerbated by some elements, such as roads and power lines, which may become filters or barriers to wildlife movements. In order to mitigate mortality and restore connectivity, wildlife passages are being constructed as linear corridors. The installation of these mitigation measures must be followed by systematic monitoring, in order to evaluate their use and effectiveness, to assist in their management, and to convince stakeholders of their value. In this paper we present the results of a monitoring study of the use of rope overpasses developed near a protected area in Porto Alegre, southern Brazil. The canopy bridges were installed by the Urban Monkeys Program in places where electric hazards... |

The Saguinus represent the basal genus of the Callitrichinae subfamily. Traditionally this genus is divided into three groups: Hairy, Mottled and Bare-face, however, molecular data failed to validate these groups as monophyletic units, as well as raised some subspecies to the species status. This is the case of the former subspecies Saguinus midas midas and S. midas niger, which are now considered as different species. In the present study, we sequenced a portion of the D-loop mtDNA region in populations from the East bank of the Xingu and from both banks of the Tocantins river, in order to test the effectiveness of large rivers as barriers to the gene flow in Saguinus. According to our results, the populations from the East and West banks of the Tocantins... |

O Pantanal é reconhecido como um importante refúgio da fauna silvestre. Entretanto, apesar de alguns inventários já terem sido realizados no Pantanal, sua fauna de mamíferos ainda é mal conhecida. Apesar de em geral ainda estar bem conservado, o Pantanal já sofre impactos ambientais visíveis, como mudanças no pulso de enchentes, causadas por assoreamento e/ou represamento de rios, e remoção da vegetação arbórea. Estes impactos podem ameaçar a fauna silvestre, e pesquisadores e conservacionistas se preocupam em identificar organismos indicadores da "saúde" deste bioma. Os mamíferos carnívoros são considerados bons indicadores biológicos, pois são predadores de topo e com isso dependem de toda a estrutura de presas e seus ambientes, em bom estado de... |

The phylogenetic proximity of primates to humans, along with their behavioral, biochemical, and anatomical similarities, make such animals more interesting experimental models for biomedical researches, as compared to classical laboratory animals. Another aspect that has called the attention of researchers is the differentiated quadrupedalism present in some primates. The tufted capuchin monkey uses the ground and tree branches as its support for locomotion, showing various postures while performing this task. On the basis of this information, we have decided to study the rectus abdominis muscle of the tufted capuchin monkey, with the following goals: the frequency and area of fiber types; its possible compartmentalization; and identify if this muscle is... |

Los monos neotropicales de la colección del Zoológico de la Ciudad de Mendoza (ZMA), Argentina, fueron objeto de un estudio colaborativo que incluyó la toma de medidas antropométricas y el análisis citogenético básico (alfa). Se estudiaron 13 ejemplares del género Alouatta sp. (10 hembras y 3 machos), 2 Cebus sp. (una hembra y un macho) y 3 hembras Saimiri sp. Mediante la cariología se confirmó que los Cebus del ZMA se corresponderían con C. paraguayanus (2N=54, XX/XY) y los Saimiri, con Saimiri boliviensis boliviensis (2N= 44,XX). En los aulladores se corroboró su asignación de especie como A. caraya y se observó una morfología cromosómica, compatible con el ya descrito sistema de determinación sexual múltiple X1X1X2X2/X1X2Y1Y2. La oportunidad permitió... |
