cranial computed tomography in the evaluation of neurologic disorders in two nonhuman primates.cranial computed tomography (cct) was used to evaluate neurologic disorders in 2 primates. in the 1st case, acute left hemiparesis developed in an adult female proboscis monkey (nasalis larvatus). a cct scan revealed a right frontal lobe abscess that was subsequently surgically drained. in the 2nd case, a juvenile black spider monkey (ateles fusciceps) experienced recurrent seizures following an episode of trauma and anoxia. a cct scan demonstrated enlarged lateral ventricles and cerebral atroph ...19817328009
isolation and characterization of simian t-cell leukemia virus type ii from new world monkeys.since the description of human t-cell leukemia virus type i (htlv-i) and its simian counterpart, simian t-cell leukemia virus type i (stlv-i), the possible existence of other related simian retroviruses has been raised. here, we report a new retrovirus, stlv-ii, which we have identified in spider monkeys (ateles fusciceps), a new world primate species. initially, a recombinant htlv-ii envelope protein (rp-iib) was used to identify anti-stlv-ii antibodies in new world monkeys by western blot (imm ...19947507178
failure to detect human t-lymphotropic virus antibody in wild-caught new world primates.we conducted a study to look for a simian counterpart of human t-lymphotropic virus (htlv) in wild-caught monkeys in the republic of panama. serum specimens were obtained from 102 monkeys (ateles fusciceps, n = 75; alouatta villosa, n = 18; and cebus capucinus, n = 9) captured in panama's darien rain forest in 1979-1980. specimens were screened for htlv antibody by enzyme-linked immunosorbent assay, and reactive specimens were further tested by western blot. none of the 102 specimens were seropo ...19938102837
rflp analysis of mtdna from six platyrrhine genera: phylogenetic inferences.this study investigates the phylogenetic relationships of 10 species of platyrrhine primates using rflp analysis of mtdna. three restriction enzymes were used to determine the restriction site haplotypes for a total of 276 individuals. phylogenetic analysis using maximum parsimony was employed to construct phylogenetic trees. we found close phylogenetic relationships between alouatta, lagothrix and ateles. we also found a close relationship between cebus and aotus, with saimiri clustering with t ...200312759493
footfall patterns, stride length and speed of vertical climbing in spider monkeys (ateles fusciceps robustus) and woolly monkeys (lagothrix lagotricha).vertical climbing is central to theories surrounding the locomotor specialisations of large primates. in this paper, we present spatiotemporal gait parameters obtained from video recordings of captive spider monkeys (ateles fusciceps robustus) and woolly monkeys (lagothrix lagotricha) in semi-natural enclosures, with the aim of discovering the influence of body weight and differences in general locomotor behaviour on vertical climbing kinematics on various substrates. results show that there are ...200415240978
The vomeronasal organ of New World monkeys (platyrrhini).Although all platyrrhine primates possess a vomeronasal organ (VNO), few species have been studied in detail. Here, we revisit the microanatomy of the VNO and related features in serially sectioned samples from 41 platyrrhine cadavers (14 species) of mixed age. Procedures to identify terminally differentiated vomeronasal sensory neurons (VSNs) via immunolabeling of olfactory marker protein (OMP) were used on selected specimens. The VNO varies from an elongated epithelial tube (e.g., Ateles fusci ...201122042751

arboreal locomotion in wild black-and-white snub-nosed monkeys (rhinopithecus bieti).this paper presents spatiotemporal gait parameters of arboreal locomotion in the colobine rhinopithecus bieti in its natural habitat. while adult females used exclusively either extended-elbow vertical climbing or pulse climbing, the much larger adult males preferred the less demanding flexed-elbow vertical climbing on thin trees or on trunks with handholds. if sex-specific differences are taken into consideration, the differences between flexed-elbow and extended-elbow vertical climbing in rhin ...200616612094
pendular motion in the brachiation of captive lagothrix and ateles.pendular motion during brachiation of captive lagothrix lagothricha lugens and ateles fusciceps robustus was analyzed to demonstrate similarities, and differences, between these two closely related large bodied atelines. this is the first captive study of the kinematics of brachiation in lagothrix. videorecordings of one adult male of each species were made in a specially designed cage constructed at the dumond conservancy/monkey jungle, miami, fl. java software (jandel scientific inc., san rafa ...199910402035
taxonomic notes on the pelage of ateles paniscus paniscus, a. p. chamek (sensu kellogg and goldman, 1944) and a. fusciceps rufiventris (equals a. f. robustus, kellogg and goldman, 1944).observations on specimens of ateles paniscus paniscus, a. p. chamek and ateles fusciceps rufiventris (equals a. f. robustus) reveal unreported variations in coat color and lead to expansions of the current taxonomic descriptions of these subspecies. these variants are significant for the correct identification of spider monkeys used in biomedical research and in terms of distribution and speciation within the genus ateles.1975804562
goal-directed tail use in colombian spider monkeys (ateles fusciceps rufiventris) is highly lateralized.behavioral laterality refers to a bias in the use of one side of the body over the other and is commonly studied in paired organs (e.g., hands, feet, eyes, antennae). less common are reports of laterality in unpaired organs (e.g., trunk, tongue, tail). the goal of the current study was to examine tail use biases across different tasks in the colombian spider monkey (ateles fusciceps rufiventris) for the first time (n = 14). we hypothesized that task context and task complexity influence tail lat ...201829239649
network analysis as a tool to understand social development in spider monkeys.the emerging field of network science has demonstrated that an individual's connectedness within their social network has cascading effects to other dimensions of life. like humans, spider monkeys live in societies with high fission-fusion dynamics, and are remarkably social. social network analysis (sna) is a powerful tool for quantifying connections that may vary as a function of initiating or receiving social behaviors, which has been described as shifting social roles. in primatology, the sn ...202032794244
the body center of mass in primates: is it more caudal than in other quadrupedal mammals?whole body center of mass (bcom) position values are lacking for a comparative sample of primates. therefore, it still remains unknown whether the bcom in primates is more posteriorly located than in other mammals. the aim of the present report is to provide data for a large sample of primate species and to compare the position of the bcom in primates to non-primate mammals.201930839107
determination of vertebral heart score in three species of spider monkey (ateles fusciceps, a. hybridus and a. paniscus).the vertebral heart score (vhs) is a method of evaluation of cardiac size well documented in domestic mammals and in other primate species, and the aim of this study was to determine the vhs in three species of spider monkey.201728561884
comparison of forest regeneration in two sites with different primate abundances in northwestern ecuador.there is increasing evidence that large-bodied primates play important roles as seed dispersers andin the maintenance of tree diversity in forest ecosystems. in this study we compared forest regeneration at twosites with differing primate abundances in the ecuadorian chocoan rainforest. we predicted: (1) significant differencesin primate abundance between the two sites; (2) higher understory tree species richness and density atthe site with greater primate abundance; (3) the site with lower prim ...201629451750
ancestral resurrection of anthropoid estrogen receptor β demonstrates functional consequences of positive selection.anthropoid primates arose during the eocene approximately 55 million years ago (mya), and extant anthropoids share a most recent common ancestor ∼40mya. paleontology has been very successful at describing the morphological phenotypes of extinct anthropoids. less well understood is the molecular biology of these extinct species as well as the phenotypic consequences of evolutionary variation in their genomes. here we resurrect the most recent common ancestral anthropoid estrogen receptor β gene ( ...201728916155
role of the prehensile tail during ateline locomotion: experimental and osteological evidence.the dynamic role of the prehensile tail of atelines during locomotion is poorly understood. while some have viewed the tail of ateles simply as a safety mechanism, others have suggested that the prehensile tail plays an active role by adjusting pendulum length or controlling lateral sway during bimanual suspensory locomotion. this study examines the bony and muscular anatomy of the prehensile tail as well as the kinematics of tail use during tail-assisted brachiation in two primates, ateles and ...200515386296
identification of mhc i class genes in two platyrrhini species.the major histocompatibility complex is a diverse gene family that plays a crucial role in the adaptive immune system. in humans, the mhc class i genes consist of the classical loci of hla-a, -b, and -c, and the nonclassical loci hla-e, -f, and -g. in platyrrhini species, few mhc class i genes have been described so far and were classified as mhc-e, mhc-f, and mhc-g, with mhc-g possibly representing a classical mhc class i locus while there were arguments about the existence of the mhc-b locus i ...201525573376
precise digit use increases the expression of handedness in colombian spider monkeys (ateles fusciceps rufiventris).decades of research on the hand use patterns of nonhuman primates can be aptly summarized by the following phrase: measurement matters. there is a general consensus that simple reaching is a poor indicator of handedness in most species, while tasks that constrain how the hands are used elicit individual, and in some cases, population-level biases. the tube task has become a popular measure of handedness, although there is variability in its administration across studies. the goal of this study w ...201526339782
embraces are lateralized in spider monkeys (ateles fusciceps rufiventris).side biases observed in behavior are thought to reflect underlying asymmetric brain function or hemispheric specialization. previous work in multiple species identified left side biases (associated with the right hemisphere) for processing social behavior. in highly social species such as primates, many behaviors may be categorized as social, yet differences between such behaviors have not been examined as a test of asymmetric brain function. using colombian spider monkeys (ateles fusciceps rufi ...201728346692
