| This document is a description of the macroscopic functional anatomy of the ulna bony prominences in the White-footed Tamarin (Saguinus leucopus), a neotropical endemic, and monotypic primate of Colombia. Few studies have been conducted on its anatomy, and thus its ulnar morphology, an essential element for this animal's quadrupedal arboreal locomotion, remains unknown. This study is based on eight specimens, fixed in formalin at 10 % whose ulnas were extracted in order to describe the main bony prominences along with muscular and ligamentous fixation functions. These elements of the locomotor apparatus and the multiple anatomical contours of the ulna of the White-footed Tamarin, exhibit characteristics for positional and articular adjustment with other... |

| The aim was to understand the anatomical features of the venous valve in Macaca fascicularis and to compare it with that of humans. The bilateral lower limbs (24 limbs from 12 animals) of Macaca fascicularis cadavers were dissected, and the femoral veins (FVs) were equally divided into distal, intermediate, and proximal sections. The external diameter of the FV in each section was measured. The venous valves were observed microscopically and stained with hematoxylin and eosin as well as trichrome. Data describing the human venous valve were collected from the current literature. No great saphenous veins were found among the 24 lower limbs from the Macaca fascicularis cadavers. The external diameters of the FVs in the distal, intermediate, and proximal... |

| El Saguinus leucopus es un primate neotropical, endémico y monotípico de Colombia, con escasos estudios sobre su anatomía, en especial de sus músculos, siendo estos un elemento fundamental para la locomoción activa de este primate en los árboles. El objetivo del presente estudio fue describir la anatomía macroscópica del músculo braquiorradial del tití gris (Saguinus leucopus), tomando como base del estudio diez especímenes fijados con formalina al 10%, y a cada uno de ellos se les disecó los dos miembros torácicos de superficial a profundo, describiendo la forma, el origen, la inserción, la inervación y la irrigación del músculo braquiorradial. Se concluye que es un músculo que presenta una morfología, que debe contribuir a los movimientos flexores y... |

| El Saguinus leucopus es un primate neotropical, endémico y monotípico de Colombia, con escasos estudios sobre su anatomía, cuya morfología humeral permanece desconocida siendo un elemento fundamental para la locomoción cuadrúpeda de este animal arbóreo. El objectivo del presente estudio fue describir la anatomía macroscópica y la función de los relieves óseos del húmero del titi gris Saguinus leucopus. Se tomaron como base del estudio ocho especímenes fijados con formalina al 10% y de ellos se extrajeron sus húmeros, describiendo las principales funciones de los relieves óseos, como fijaciones musculares y canalizaciones neurovasculares. Los variados relieves anatómicos del húmero del titi gris presentan una disposición morfológica coincidente con sus... |

| The Saguinus leucopus is an endemic and monotypic primate of Colombia with quadrupedal arboreal locomotion, but the study of its morphological adaptations are still scarce, therefore the specific knowledge of its muscles will allow to understand these adaptations and to establish better medical and surgical procedures in order to preserve this species. For this purposes, the two forearms of 10 S. leucopus specimens were dissected, they were fixed within a formaldehyde solution, phenic acid and mineral oil mixture. Among the craniolateral muscles of the forearm two muscles were independent for digits IV and V. They presented form, origin and insertion suitable for individual extension of each digit, with innervation and irrigation by the cranial... |

| ABSTRACT This is the first report of parasitism by Gongylonema sp. in a free-ranging callitrichid from the Atlantic forest of Espírito Santo, Brazil. A juvenile male of Geoffroy's marmoset (Callithrix geoffroyi) was euthanized due to poor prognosis, then necropsied. Samples of the tongue were collected for routine histological processing. Microscopically, there were transversal sections of adult nematodes within the epithelial layer of the mucosa of the tongue. Lingual scraping demonstrated a small number of oval embryonated eggs with a thick capsule. The morphology of the adult parasites and the eggs, associated with its location, were compatible with the Spirurida nematode of the genus Gongylonema. Further studies are needed to evaluate the impact of... |

| BACKGROUND: Chemerin, encoded by the retinoic acid receptor responder 2 (RARRES2) gene is an adipocytesecreted protein with autocrine/paracrine functions in adipose tissue, metabolism and inflammation with a recently described function in vascular tone regulation, liver, steatosis, etc. This molecule is believed to represent a critical endocrine signal linking obesity to diabetes. There are no data available regarding evolution of RARRES2 in non-human primates and great apes. Expression profile and orthology in RARRES2 genes are unknown aspects in the biology of this multigene family in primates. Thus; we attempt to describe expression profile and phylogenetic relationship as complementary knowledge in the function of this gene in primates. To do that, we... |

| Monitoring the influence of human actions on flagship species is an important part of conserving biodiversity, because the information gained is crucial for the development and adaptation of conservation management plans. On the Masoala Peninsula in Madagascar, we are monitoring the two largest prosimian species, Eulemur fulvus albifrons and Varecia variegata rubra, at disturbed and undisturbed forest sites to determine if extraction of forest resources has a significant impact on the population viability of these species. To test the sensitivity of lemur species to routine extraction of natural resources by local villagers, we compared population demography and density for both species across six study sites, using a new census technique. Three of the... |

| The dorsal surface of the tongues of the Slow Loris and the Pygma Slow Loris were examined by employing scanning electron microscopy techniques. Three types of the papillae are present on their dorsal surface of the tongue: filiform, fungiform and vallate. The filiform papillae are located the apex and the body of the tongue, and we observed that each of them has a gustatory pore. The fungiform papillae, scattered singly among the filiform papillae, distribute mainly on the apex of the tongue. The vallate papillae are located along the diversing arms of the V-shaped boundary between the anterior and posterior regions of the tongue. In addition, no foliate papillae were observed. The morphological characteristics of the dorsal surface of the tongues in Slow... |

| This paper reports the behavior of the black capped capuchin monkey, Cebus apella, using tools to break seeds of Syagrus romanzoffianum in search of coleoptera larvae that live inside. The study area was the Parque Municipal Arthur Thomas (85,47 ha) located in the city of Londrina, Paraná state. In one year of study, using the ad libitum method, the monkeys were observed using rocks pretty much in the same way as if they were hammer and anvil. Individuais of both sexes including adults, subadults and juveniles with more than two years of age, were involved in such activity. The behavior of the animais consisted of they place the seeds on a large rock in the ground, and using a smaller rock which was hold among the hands, the seeds were beaten repeatedly... |

| In this paper, the topology of cortical visuotopic maps in adult primates is reviewed, with emphasis on recent studies. The observed visuotopic organisation can be summarised with reference to two basic rules. First, adjacent radial columns in the cortex represent partially overlapping regions of the visual field, irrespective of whether these columns are part of the same or different cortical areas. This primary rule is seldom, if ever, violated. Second, adjacent regions of the visual field tend to be represented in adjacent radial columns of a same area. This rule is not as rigid as the first, as many cortical areas form discontinuous, second-order representations of the visual field. A developmental model based on these physiological observations, and... |
