A subfamily in the family ATELIDAE, comprising three genera: woolly monkeys (Lagothrix), spider monkeys (Ateles), and woolly spider monkeys (Brachyteles).

Functional morphology of the first cervical vertebra in humans and nonhuman primates. (1/34)

The cervical vertebral column bears or balances the weight of the head supported by the nuchal muscles that partly originate from the cervical vertebrae. The position of the head relative to the vertebral column, and consequently locomotion and posture behavior, could thus be associated with the form of the cervical vertebrae. In spite of this assumption and some empirical indications along these lines, primate vertebral morphologies have been reported to be very similar and not clearly related to locomotion. We therefore study the relationship between the morphology of the first cervical vertebra, the atlas, and the locomotion pattern within primates using a geometric morphometric approach. Our analysis is based on a total of 116 vertebrae of adult Homo sapiens, Gorilla gorilla, Pan troglodytes, Pongo pygmaeus, Hylobates lar, Macaca mulatta, Papio hamadryas, Ateles geoffroyi, and Alouatta palliata. On each atlas, 56 landmarks were digitized and superimposed by Procrustes registration. The resulting shape variables were analyzed by principal component analysis, multivariate regression, and partial least-squares analysis. We found that the nine primate species differ clearly in their atlas morphology and that allometric shape change is distinct between the nonhuman primates and Homo sapiens. We could further identify morphological features that relate to the species' locomotion pattern. Human atlas shape, however, cannot be predicted by an extrapolation of the nonhuman primate model. This implies that either the primate atlas is generalized enough to allow bipedal locomotion or else the human atlas morphology is a unique adaptation different from that in the more orthograde nonhuman primates.  (+info)

Aggression and conflict management at fusion in spider monkeys. (2/34)

In social systems characterized by a high degree of fission-fusion dynamics, members of a large community are rarely all together, spending most of their time in smaller subgroups with flexible membership. Although fissioning into smaller subgroups is believed to reduce conflict among community members, fusions may create conflict among individuals from joining subgroups. Here, we present evidence for aggressive escalation at fusion and its mitigation by the use of embraces in wild spider monkeys (Ateles geoffroyi). Our findings provide the first systematic evidence for conflict management at fusion and may have implications for the function of human greetings.  (+info)

Rapid evolution of an X-linked microRNA cluster in primates. (3/34)

MicroRNAs (miRNAs) are a growing class of small RNAs (about 22 nt) that play crucial regulatory roles in the genome by targeting mRNAs for cleavage or translational repression. Most of the identified miRNAs are highly conserved among species, indicating strong functional constraint on miRNA evolution. However, nonconserved miRNAs may contribute to functional novelties during evolution. Recently, an X-linked miRNA cluster was reported with multiple copies in primates but not in rodents or dog. Here we sequenced and compared this miRNA cluster in major primate lineages including human, great ape, lesser ape, Old World monkey, and New World monkey. Our data indicate rapid evolution of this cluster in primates including frequent tandem duplications and nucleotide substitutions. In addition, lineage-specific substitutions were observed in human and chimpanzee, leading to the emergence of potential novel mature miRNAs. The expression analysis in rhesus monkeys revealed a strong correlation between miRNA expression changes and male sexual maturation, suggesting regulatory roles of this miRNA cluster in testis development and spermatogenesis. We propose that, like protein-coding genes, miRNA genes involved in male reproduction are subject to rapid adaptive changes that may contribute to functional novelties during evolution.  (+info)

Nonhuman anthropoid primate femoral neck trabecular architecture and its relationship to locomotor mode. (4/34)

Functional analyses of human and nonhuman anthropoid primate femoral neck structure have largely ignored the trabecular bone. We tested hypotheses regarding differences in the relative distribution and structural anisotropy of trabecular bone in the femoral neck of quadrupedal and climbing/suspensory anthropoids. We used high-resolution X-ray computed tomography to analyze quantitatively the femoral neck trabecular structure of Ateles geoffroyi, Symphalangus syndactylus, Alouatta seniculus, Colobus guereza, Macaca fascicularis, and Papio cynocephalus (n = 46). We analyzed a size-scaled superior and inferior volume of interest (VOI) in the femoral neck. The ratio of the superior to inferior VOI bone volume fraction indicated that the distribution of trabecular bone was inferiorly skewed in most (but not all) quadrupeds and evenly distributed the climbing/suspensory species, but interspecific comparisons indicated that all taxa overlapped in these measurements. Degree of anisotropy values were generally higher in the inferior VOI of all species and the results for the two climbing/suspensory taxa, A. geoffroyi (1.71 +/- 0.30) and S. syndactylus (1.55 +/- 0.04), were similar to the results for the quadrupedal anthropoids, C. guereza (male = 1.64 +/- 0.13; female = 1.68 +/- 0.07) and P. cynocephalus (1.47 +/- 0.13). These results suggest strong trabecular architecture similarity across body sizes, anthropoid phylogenetic backgrounds, and locomotor mode. This structural similarity might be explained by greater similarity in anthropoid hip joint loading mechanics than previously considered. It is likely that our current models of anthropoid hip joint mechanics are overly simplistic.  (+info)

Neuroendocrine tumor in the lung of a captive black spider monkey (Ateles paniscus). (5/34)

This paper describes a neuroendocrine (NE) tumor of the lung that was observed during the necropsy of a 14-year-old female black spider monkey (Ateles paniscus) with sudden death. Grossly, multifocal firm and coalescing nodular masses were observed in the lung. The histological examination showed the tumor to be an typical NE tumor with polygonal cells grouped in small solid aggregates, with regularly sized, spherical, centrally placed nuclei with modest, lightly granular cytoplasm suspended in a fibrovascular stroma. The immunohistochemical examination revealed the tumor to be positive for cytokeratin, chromogranin A and synaptophysin, and negative for CD56. To the best of our knowledge, this is the first report of NE tumor in the lung of the black spider monkey.  (+info)

The complete nucleotide sequence of a New World simian foamy virus. (6/34)

We determined the complete nucleotide sequence of the New World simian foamy virus (FV) from spider monkey (SFVspm). Starting from a conserved region in the integrase (IN) domain of the pol gene we cloned fragments of the genome up to the 5' end of the long terminal repeat (LTR) into plasmid vectors and elucidated their nucleotide sequence. The 3' end of the genome was determined by direct nucleotide sequencing of PCR products. Each nucleotide of the genome was determined at least two times from both strands. All protein motifs described to be conserved among primate FVs were found in SFVspm. At both the nucleotide and protein levels SFVspm is the most divergent primate FV described to date, reflecting the long-term phylogenetic separation between Old World and New World primate host species (Catarrhini and Platyrrhini, respectively). The molecular probes developed for SFVspm will allow the investigation of trans-species transmissions of this New World foamy virus to humans by serological assays.  (+info)

Fission-fusion dynamics, behavioral flexibility, and inhibitory control in primates. (8/34)

 (+info)

Spider monkeys are New World monkeys of the family Atelidae, subfamily Atelinae. Found in tropical forests from southern Mexico to Brazil, spider monkeys belong to the genus Ateles; the closely related woolly spider monkeys are in the genus Brachyteles.. As they require large tracts of undisturbed forest and specialize on ripe fruits, spider monkeys may be considered an indicator species. The monkeys are threatened by habitat destruction through continued growth in South American agriculture. Disproportionately long, spindly limbs inspired the spider monkeys common name. Their deftly prehensile tails have highly flexible hairless tips.. Spider monkeys have hook-like, narrow and thumbless hands; the fingers are elongate and recurved. The hair is coarse, ranging in color from a ruddy gold to brown and black; the hands and feet are usually black. Heads are small with hairless faces. An unusually long labia in females may be mistaken for a penis; it is used to attract the males. A female will ...

Black spider monkeys are habitat specialists and are almost always seen in undisturbed, primary rainforest and do not utilize edge habitats (Mittermeier & van Roosmalen 1981; Lehman 2004b). Like other species of spider monkeys, black spider monkeys occupy the upper layers of the rainforest and forage in the high canopy (from 25 to 30 m [82.0 to 98.4 ft]) consuming primarily fruits, but also occasionally consuming leaves, flowers, and insects (van Roosmalen & Klein 1988; Russo et al. 2005). As large-bodied frugivores, black spider monkeys are important seed dispersers within the rainforest ecosystem and play a crucial role in regenerating tropical forests (van Roosmalen 1985; Russo et al. 2005). Compared to other sympatric species of primates, black spider monkeys exhibit low diet diversity because of their high levels of fruit consumption (Guillotin et al. 1994). Despite their dependence on fruit as the mainstay of their diet, black spider monkeys supplement their fruit consumption during ...

Also known as the black-handed spider monkey, Geoffroys Spider Monkey originates from parts of Mexico and possibly Colombia. There are 5 subspecies of
Spider monkeys form loose groups of 15-25 individuals. During the day, spider monkey groups break up into smaller subgroups of two to eight individuals; this social structure (fission-fusion) is found in only one other primate, the chimpanzee. The size of subgroups and the degree to which they will avoid each other during the day is determined by food competition and the risk of predation. Each group is closely associated with its territory (Gordon 2007).. Also less common in primates, females-rather than males-disperse at puberty to join new groups. Males tend to stick together for their whole life. Hence, males in a group are more likely to be related and have closer bonds than females. The strongest social bonds are formed between females and young offspring. Groups are thought to be directed by a lead female, who is responsible for planning an efficient route for the days feeding activities.. Spider monkeys are diurnal and spend the night sleeping in carefully trees. Grooming is not as ...

The social organization of black spider monkeys is closely related to their ecological niche as large-bodied frugivores. In addition to ranging over large areas to find the amount of fruit necessary to meet their feeding requirements, black spider monkeys exhibit another behavior that helps them cope with seasonally restricted fruit. Like chimpanzees (Pan troglodytes), spider monkeys exhibit a fission-fusion social system; there is a large community of individuals that regularly associate with one another but individuals within the larger community spend much of their time traveling in smaller, temporary sub-groups led by dominant adult females (Mittermeier & van Roosmalen 1981; van Roosmalen 1985). Spider monkeys break up into small foraging groups that travel together and feed throughout the day within a core area of the larger groups home range (Simmen & Sabatier 1996). The subgroups or parties that are formed by individuals within the troop are temporary and can change in composition ...

Luum was an adult female of the Coba group, daughter of Yaax (green in Mayan) and older sister of the little Kiin (sun in Mayan). She was one of the most cheerful and playful individuals in the group, she loved to play with all the members of the group and from time to time she wanted to play with the other primates that followed and observed her daily (us!). She was an excellent leader; we saw her move ahead of her mother in the forest and let her know if she saw any other monkeys. However, her time in the group came to an end when she reached sexual maturity. As is part of spider monkey life, the females migrate from the group to find another group and form their own family, while the males stay for their entire lives in the group they were born (this is known as philopatry). And this time Luum was no exception. When she reached sexual maturity and learned everything a spider monkey must know to leave home, she left the subgroup in search of a new home. ...
Negra lived as a pet from a very young age with a family in Ascensión de Guarayos. She remained tied to a tree by a chain, surrounded by a group of pigs. The staff of Parque Ambue Ari used to see Negra every week when they went to buy fruits and vegetables for the animals at the sanctuary. They tried to explain to Negras captors that it is illegal to keep monkeys as pets and that they should release her to CIWYs care. The family refused, until one day Negra freed herself, entered the neighbors house and caused great damage. After this, the family allowed CIWY to take Negra.. Negra initially came to Ambue Ari, but was transferred to Machía so that she could integrate into the group of spider monkeys there. Spider monkeys are very social animals and fortunately Negra was immediately accepted by the group.. Despite being over 20 years old, Negra is a very active monkey. Everything arouses her curiosity and she enjoys exploring the area for new stimuli. Her intelligence never ceases to amaze ...

PSA is a 32 kDa single chain glycoprotein serine protease with a chymotrypsin like specificity produced by the secretory epithelium of the prostate gland (1). PSA is normally secreted into the seminal fluid and plays a functional role in the cleavage of the seminal vesicle proteins and the liquefaction of the seminal coagulum (2). Only low levels of PSA are normally present in the blood stream, and increasing serum concentrations indicate prostatic pathology, including benign prostatic hyperplasia and cancer of the prostate. Determination of PSA is now widely used for detection and management of patients with prostatic cancer and considered as the superior serological marker for cancer of the prostate (3, 8 ...

Nesomyines are characterized by their morphological and ecological diversity. Typically they are medium to large gerbil-like, vole-like, or rat-like rodents. They measure 80 to 350 mm in head and body length and their tails range from 60 to 250 mm. Nesomyines weigh 21 to 1,500 grams. In some species, females weigh less than males, in other species, there is no sexual dimorphism. Nesomyine tails are short to long, naked to moderately furred, and sometimes tufted. Some have prehensile tails. The hind feet range from wide and short to narrow and long, and most have no hair on the soles. The pelage is long and soft or thick and woolly. It is sandy brown, reddish, or gray on the dorsum and yellowish white, white, or gray on the venter. Most nesomyines have large eyes and prominent ears and whiskers.. The nesomyine dental formula is 1/1, 0/0, 0/0, 3/3 = 16. The incisors are opisthodont. The molars are rooted, have a biserial cusp arrangement, and range from brachydont to hypsodont. In most species, ...

Crested geckos have a relatively large, triangular head, with two large eyes and two relatively large ear openings on either side of the head. Very fine light tan, peach, or reddish brown-colored granular scales cover their long bodies. They have moderately thick, prehensile tails. The back typically has a pattern of lateral, darker stripes. Thin, continuous, calcareous crest, project along either side of the back and also above the eyes and portions of the limbs. Above the eyes, these crests seem to serve primarily to keep dust and other particles out, but it is unknown what purpose is served by the dorsal and limb crests; they may be used in discriminating between potential mates. There are three color morphs that appear in wild crested geckos: patternless, tiger, and white-fringed. Patternless crested geckos are more or less solid in color, ranging from yellow, green, brown, red, to gray, and have very faint or no pattern present on the back. Tiger crested geckos have a light colored ...
This family comprises the seahorses and true pipefishes. Their body is typically slender and elongate, and is encased in a series of bony rings. They may or may not have a prehensile tail. Their snouts are long and tube-like, and the toothless mouth is located at the tip. Most species feed on tiny benthic and planktonic organisms. Interestingly, the females deposit their eggs on the belly or base of the tails of the males, either in a pouch or a special surface full of blood vessels. The males will fertilise the eggs and carry them until they hatch. Many species are dried and sold in the curio trade, or used in traditional medicine in Asia ...

Summary 1. We received a juvenile squirrel-monkey, Leontocebus geoffroyi (Pucheran) with a naturally acquired spirochetosis on May 20, 1930. This animal had been in captivity for a short time in the region of Arraijan and La Chorrera, Republic of Panama. This region has long been known as an endemic center for relapsing fever. 2. We secured, in August, 1930, two monkeys of this same species that were positive for a scant or latent infection of apparently the same spirochete. These animals were captured in the jungle at a point on the banks of the Tuira river above Boca de Cupe, Dárien Province, Republic of Panama. Twenty other specimens captured on the same expedition failed to show the infection. All were post mortem examinations. 3. We have passed the spirochetal infection from the squirrel-monkeys to white mice, white rats, one guinea pig, white-faced monkeys (Cebus capucinus imitator Thomas), red spider monkeys (Ateles geoffroyi Kuhl), a night monkey (Aotus zonalis Goldman) and to numerous
Fecal glucocorticoid metabolites (e.g., cortisol) are a valuable non-invasive source of information on individual levels of physiological stress. However, using them to evaluate stress levels among females can be problematic in species that do not show overt signs of reproductive condition because concentrations of reproductive hormones can affect cortisol concentrations. For example, high concentrations of estradiol during pregnancy may promote an increase in glucocorticoids and associated binding factors. Here, we examine the efficacy of using fecal glucocorticoid metabolites as an indicator of stress and whether estradiol is a potential confound of such measurements in both wild (El Zota, Costa Rica) and captive (Brookfield Zoo, Illinois) black-handed spider monkeys (Ateles geoffroyi). First, fecal cortisol concentrations were measured from captive female spider monkeys before and after a veterinary exam. All females exhibited elevated cortisol concentrations after this stressful experience, ...
New World monkeys are primates and are more closely related to humans, apes and Old World monkeys than any other living nonhuman primate group. The Smithsonian Institutions Division of Mammals ( http://vertebrates.si.edu/mammals/ ) houses many New World monkeys in its scientific collections.
Brachiation (from brachium, Latin for arm), or arm swinging, is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb. This form of locomotion is the primary means of locomotion for the small gibbons and siamangs of southeast Asia. Some New World monkeys such as spider monkeys and muriquis are semibrachiators and move through the trees with a combination of leaping and brachiation. Some New World species also practice suspensory behaviors by using their prehensile tail, which acts as a fifth grasping hand. Some traits that allow primates to brachiate include a short spine (particularity the lumbar spine), short fingernails (instead of claws), long curved fingers, reduced thumbs, long forelimbs and freely rotating wrists. Modern humans retain many physical characteristics that suggest a brachiator ancestor, including flexible shoulder joints and fingers well-suited for ...

Modern platyrrhines live in Central and South America but its not entirely clear how their common ancestor got there. At the time, around 25 million years ago, the Panama land bridge that connected North and South American hadnt formed, and the Atlantic Ocean was narrower. Its possible that this ancient monkey rafted across from Africa. No matter how it got there, what happened next is clearer thanks to Perelmans study.. After they reached South America, the platyrrhines diverged into three major families. The first to branch off were the pithecids, including the titis, the bald-faced uakaris (top left), the bearded sakis. Next came the atelids with their long, prehensile tails, including the howler (bottom right), spider and woolly monkeys.. Finally, the cebids. This group includes several species that have previously been classified in separate families; Perelman has decided to united them in one. They diverged in quick succession - first, the capuchins and squirrel monkeys (bottom left), ...

Have you ever heard of a pack of wolves, meercats, spider monkeys, chimps, gorillas, howler monkeys, lions, elephants, etc. living in five hundred to thousand individual size groups or shall we say herds? All of them and a mass of other such small group animals live in groups in numbers per group that stays within a certain range. In most, there is an alpha male whom the group revolves around. There will be sub-alphas who support him but one of which will ultimately replace him. When the group gets behond its usual size, it begins to become difficult to keep together. There is more dissention. If the alpha is weak, females will leave with their offspring or another male becomes dominant. With some groups, its the head female that is dominant. A too large group encourages the sub-dominant male to split off with some of the females. Nothing can make the females, gays and children more uneasy and insecure than if the group is large enough that the dominant male has more females than he can control ...

Experiments designed to ascertain the reason for the cessation of growth of heart fibroblasts when they are cultivated in a plasma coagulum with embryo juice as nutrient fluid have shown that it is due, first, to the gradual removal of serum from the coagulum, and second, to an insufficient supply of embryo juice. In a medium containing embryo extract at 66 per cent concentration and serum at 8 per cent concentration, growth continued until the entire coagulum in a 3½ cm. flask was covered with tissue. The serum is needed to furnish additional nutriment, and also to prevent digestion of the coagulum.. ...
Antitrombina (AT), uma proteína membro da família dos inibidores de serino proteases, é uma glicoproteína que co-existe em duas isoformas, a e b, que se diferenciam pelo conteúdo de glicosilação e pela afinidade por glicosaminoglicanos (GAG), um grupo de polissacarídeos polisulfatados, dentre as quais se destaca a heparina. AT é ativada quando ligada a GAGs, tornando-se assim capaz de inibir, com alta eficiência, proteases da cascata de coagulação como trombina e fXa. Essas enzimas formam complexos ternários com heparina e AT, sendo cada uma subsequentemente inibidas preferencialmente por um mecanismo de ação distinto: [1] baseado em mudanças conformacionais (fXa), ou pelo [2] mecanismo de ponte (trombina). Adicionalmente, já foi observado que heparina isoladamente pode modular a atividade catalítica de fIIa e fXa. Considerando a falta de dados estruturais a respeito dos efeitos da glicosilação sobre a estrutura e flexibilidade de AT, bem como sobre o reconhecimento ...
