Hernández-Camacho's black-mantle tamarin, This page was last edited on 24 December 2020, at 19:12. What are three examples of Cebids? Also, two superficially similar (by clinging to a vertical support in an upright posture) behaviors have totally different underlying morphologies. In the Callitrichidae, the large energetic burden of carrying twin offspring may be important in the evolution of helper behavior. Adaptive Radiation From the family Cercopithecoidea, there are two subfamilies. Based on these findings, marmosets and tamarins may be useful in the study of atherosclerosis in relation to ovarian dysfunction, psychosocial stress, and for studies of the mechanisms by which females are protected from atherosclerosis relative to males. [5][6], Ancestral stem-callitrichids likely were "normal-sized" ceboids that were dwarfed through evolutionary time. Quite the same Wikipedia. Favorite foods should be offered. This examination is repeated at the end of the quarantine period, and can be done either with alert or anaesthetised animals, depending on the animal. A unique advantage of the Callitrichidae family as model of atherosclerosis is that they are characterized by twinning, potentially allowing genetically identical animals to be assigned to different experimental conditions in the same study. The dorsal side of the hand and fingers is covered with fine brownish-black hairs. Some platyrrhines possess which trait that is lacking other primates? Unlike other male primates, male callitrichids generally provide as much parental care as females. Examples of these include the Cotton Top Tamerin, the Emperor Tamerin, the Golden Lion Tamarin, the Common Marmoset, the Silvery Marmoset, the Pygmy Marmoset, and the Golden-White Tassel-Ear Marmoset. The lips of the common marmoset contain large, acinous, ramified sebaceous glands. Apart from studies within the family Bathyergidae, it is valuable when addressing questions about social evolution to compare sociality, ecology, and the mechanisms and degree of reproductive suppression between different mammalian taxa as well as discussing the family Bathyergidae. Below is a massive list of callitrichidae words - that is, words related to callitrichidae. However, baboons are large, requiring significant resources to house, and are highly aggressive, which limits the extent of clinical neurological evaluation that can be practically conducted. Data related to Callitrichinae at Wikispecies. question. Marmosets and tamarins are small, South American primates of the subfamily Callitrichidae. As these males are offspring of the breeding male, the lack of sexual behavior presumably results from an incest avoidance mechanism. Capuchin monkeys also use their prehensile tail (which does not have a tactile friction skin area) actively as additional support during locomotion and feeding activities. Includes many callitrichids, especially marmosets 2 Insectivores. Notice the position of the hallux. There are several recognized species, with the smallest close in size to some of the larger extant colobines, and males of the largest species weighed over 50 kilograms (110 lb). Some causes of morbidity and mortality include inappropriate housing and diet, disease and trauma related to social stress, wasting marmoset … Other articles where Cercopithecoidea is discussed: primate: Classification: Superfamily Cercopithecoidea 1 family with 21 genera. The reproductive potential of marmosets is often cited as 4.0–4.5 young/year or up to 80 offspring in a lifetime. Medial view of the left foot of the common marmoset showing the presence of a flat nail on the hallux, which contrasts with the claws on the other toes. 2.6). The skin of the palms and soles of the marmoset presents well-developed epidermal ridges. The “vertical clinging” adaptation of marmosets, facilitated by their hands and feet that are equipped with claws, is habitually practiced during harvesting of tree exudates which are usually available on the larger branches and vertical tree trunks rather than on thin, more horizontally diverging branches (Soini, 1988). If a primate possesses low, rounded molars, on which type of food do they likely primarily subsist? Similarly, there were no lesions in the control animals (Crook et al., 1990a). Notice the absence of the bunch of white-tipped hairs on the ears. The marmosets rely quite heavily on tree exudates, with some species (e.g. The epidermis is composed of a thick stratum corneum. Therefore, it is preferable for the breeding female to remain not only with her mate but also with her older offspring. Mico The Callitrichidae are quite uniform in their karyotypes They are also most interesting in relation to their karyotype evolution. Primates possessing high shearing molar crests probably follow this type of feeding pattern. Kathryn A. Shelton, ... Jay R. Kaplan, in Nonhuman Primates in Biomedical Research (Second Edition), Volume 2, 2012. This hypogonadotrophism is reversible if females are removed from their social groups or remain in their social groups and are given GnRH replacement therapy. Callithrix Colobines have longer tails, longer legs, short … Females mate with more than one male and each shares the … Indeed, the plasma lipoproteins in the common marmoset have been well characterized (Chapman et al., 1979; Forgez et al., 1983), aiding their use in toxicological studies and as a model of hepatic metabolism (Mansfield, 2003). An understanding of hematopoietic chimerism is imperative to the interpretation of their natural biology and provides an understanding of limitations for the marmoset in biomedical research. There is some suggestion that callitrichids – particularly tamarins – display more adept parenting skills if they were previously exposed to and participated in the care of younger siblings (Tardif et al., 1984; Tardif, 1997). -Cebids and Atelids: this includes spider monkeys, black wooly Monkey, Brown Wooly Monkey, Howler … Includes platyrrhines and some of the callitrichids, and many strepsirhines 3 folivores Group of primates that rely primarily on leaves for food 4 frugivores . The Catarrhini are divided into cercopithecoids (Old World monkeys) and … Test Prep. The same is true for the ultimate factors involved in the evolution and maintenance of cooperative breeding. Leontopithecus Old World monkey genera include baboons (genus Papio) and macaques (genus Macaca).Common names for other Old World monkeys … New World nonhuman primates in the Callitrichidae family (marmosets and tamarins) are uniquely capable of producing dizygotic twins that exhibit chimerism in the blood and other cells of the hematopoietic lineage (bone marrow, spleen, and thymus). Their social organization is unique among primates and is called a "cooperative polyandrous group". 2.5). Hospitalized callitrichids should be provided supplemental heat, a dark box for sleeping, and should be handled as little as possible. The hind limbs are long and equal the crown–rump length. This characteristic has resulted in the fact that the common marmoset is also known as the cotton-eared marmoset. Once the reproductive male or female dies or is removed from the group, the group may become unstable as new breeders are placed in the cage. One of the karyotypes that has been recorded for C. goeldii also resembles callithrichids by having two pairs of metacentric chromosomes and a submetacentric X-chromosome. The internarial distance is large. What type of molar pattern do the cercopithecoids express?- b) bilophodont. Such research provided the foundation for stroke research to come by establishing the concept that therapeutic intervention could reduce infarction in brain-at-risk. Palmar pads (torus metacarpeus) can be observed. Do Callitrichids eat leaves? This may exemplify a rare example of insular dwarfing in a mainland context, with the "islands" being formed by biogeographic barriers during arid climatic periods when forest distribution became patchy, and/or by the extensive river networks in the Amazon Basin. The dental formula of Callimico and the morphology of its skull are like those of the Cebidae. In particular, studies that involve genotyping and immunology must consider the source of genomic DNA and potential confounders posed by chimeric blood and lymphocytes [157]. However, they did branch off from the same species as Lemurs, Lorises, and Tarsiers. Callitrichids typically live in small, territorial groups of about five or six animals. n, Haploid number; M, metacentric; S, submetacentric; A, acrocentric; X, female sex chromosome; Y, male sex chromosome; SM, submetacentric; ST, subtelocentric. Sexual maturity – as defined by occurrence of ovulation in females and ejaculation of motile sperm in males – occurs at 11–13 months of age. The palms and soles of the common marmoset contain simple tubular eccrine sweat glands. This observation suggests that callitrichids have much flexibility in their social structures and that different species within this group may be very adaptable. These are the Cercopithecines and Colobines. However, from direct measurement of GnRH in the hypothalamus, it appears that GnRH release does not differ between nonbreeding females and breeding females in the follicular phase of their ovarian cycle. The remainder of the face is covered with black hairs. Furthermore, this region is preferred for injection of anticonception hormone implants in nonbreeding females. 8. The dorsal side of the body is covered with white-tipped black hairs that are golden brown in the middle. What do Callitrichids eat? Because of these features it was thought that callitrichids were a very primitive family of American monkeys, and suggesting that American monkeys have evolved a separate ancestor from the catarrhines. They also hang on the tip of their tails during feeding in terminal branches. In contrast to atherosclerotic lesion progression in humans, they found that the monkeys developed atherosclerotic lesions in the tongue and small intramyocardial arteries prior to development in the aorta (Dreizen et al., 1973). On the ground, woolly monkeys are quite apt in standing and walking bipedally on their hind legs, while holding the tail erect, parallel to their back. The differences of the karyotypes between Saguinus fuscicollis on the one hand and Callithrix jacchus and Leontideus illigeri on the other have been explained as the results of translocations of an acrocentric and a submetacentric pair of chromosomes producing two metacentric chromosome pairs (Egozcue et al., 1968). Pages 8 This preview shows page 4 - 7 out of 8 pages. 2.4). The only callitrichine species commonly used in biomedical research is the common marmoset (Callithrix jacchus). Hershkovitz, P. Living New World Monkeys (Platyrrhini) with an Introduction to the Primates. [4] However, some works argue that callitrichids are actually a dwarfed lineage. Yet the present study indicates variable timing of VNO ductal patency for these relatively altricial mammals. However physiological work has shown that marmosets and tamarins are actually derived simians that are more closely related to the squirrel monkeys and the … * 2011 , Matt Cartmill, Fred H. Smith, The Human Lineage , page 128, The latest major anthropoid radiation, and in some ways the most successful, was that of the Old … 167. Marmoset groups will sometimes include two breeding females if an unrelated male is present, but this configuration often leads to high infant mortality, especially due to infanticide (Rothe and Koenig, 1991; Saltzman et al., 2004, 2008). What specializations do Callitrichids have for eating exudates? The colobine monkeys are distinguished by their specialized stomachs, which have been modified for a highly folivorous, or leaf-eating, diet. 205. Marmosets are cooperative breeders – group members including the breeding male and older offspring in the group participate in the care of dependent offspring, including transport and provisioning the infants with solid food once weaning begins. Primates possessing low, rounded molars likely primarily … In both wild and captive colonies, reproduction is restricted to a single dominant breeding female, while the nonbreeders act as helpers by sharing the carrying of the twin offspring of the breeder (even at birth they constitute a burden, since their combined body mass is some 20% that of an adult). [7], Callitrichids typically live in small, territorial groups of about five or six animals. While both techniques are capable of successfully detecting chimeric tissue, neither is able to quantitate the level of chimerism within an individual or various tissue types [157]. In addition, colobines tend to live in one-male, multifemale social groupings. Common marmoset groups of 3–15 individuals in the wild are primarily extended families, but unrelated immigrants may also be found. Capuchin monkeys leap comparatively less than the smaller cebid monkeys. (1986)). This karyotype of Callimico has been used by some students as additional evidence for the taxonomic placement of this genus in the family Callitrichidae. Since this is a zoonotic disease, testing should be considered especially if there is risk of exposure. Callimico is a genus of Ceboidea that has been much discussed with regard to its systematic placement within the superfamily. Genus Cebus is basically a quadrupedal walker, climber, and runner. In species where twins are produced, the male often carries the young while the mother … Christophe Casteleyn, Jaco Bakker, in The Common Marmoset in Captivity and Biomedical Research, 2019. The third genus of the Atelinae, Lagothrix, the woolly monkeys, are predominantly quadrupedal walkers and always employ their fifth extremity (the prehensile tail with a well developed friction pad) to secure their movements. Terminal or digital pads (torus digitalis) are present on the terminal phalanx of the digits (Fig. Investigators found 15 wild-caught black-mantled tamarins (S. nigricollis) to be essentially free of aortic and coronary artery atherosclerotic lesions (Newman et al., 1974). Most imported animals arrive in a stressed condition, dehydrated and underfed and should therefore be rested (Deinhardt, 1967). The large ears are characterized by a bunch of long black hairs tipped with white (Fig. They eat insects, fruit, and the sap or gum from trees; occasionally they take small vertebrates. answer. Four large vibrissae lie near the corners of the mouth. They are gyrencephalic, possessing larger brains with a more complex cortical and subcortical organization and a vascular anatomy that resemble that of the human brain [3]. Another important mammalian group for comparative analysis of mechanisms implicated in cooperative breeding is the various mongoose species in the carnivore family Herpestidae. However, in captive “peer” groups of common marmosets consisting of unrelated adults, the dominant breeding female mates mainly with the dominant male. [9] The typical social structure seems to constitute a breeding group, with several of their previous offspring living in the group and providing significant help in rearing the young. Request PDF | Callitrichids | Callitrichids are important research models for the study of reproduction, behavior, vision, endocrinology, psychology, aging, nephropathy, and... | … Concerning systematics, while extinct monkeys from the early and middle Miocene of Africa are widely accepted as true cercopithecoids , there remains some discussion as to their precise phylogenetic position. Most of the species are considered to be endangered, threatened or vulnerable. Alouatta seniculus and A. palliata are also avid and capable swimmers (Kinsey, 1997). As estrogen priming prior to mating is needed for induction of ovulation, the implication is that even if some nonbreeding subordinate females mate, they probably will not ovulate (Creel, Creel, Wildt, and Monfort, 1992; Creel and Waser, 1997). Interaction between the dominant female and other female group members usually induces suppression of ovulation among the subordinate females (Abbott et al., 1981; Barrett et al., 1993; Kuederling et al., 1995). Define cercopithecoids. A well-defined neck is not present. Copyright © 2021 Elsevier B.V. or its licensors or contributors. All callitrichids are arboreal. However, ovulation may be suppressed for periods of years following puberty under certain conditions (Abbott, 1987; Tardif et al., 1994). As opposed to most nonhuman primates, callitrichids do not display any meaningful delays in ovulation associated with lactation. answer. Figure 2.4. Some platyrrhines possess which trait that is lacking in other primates? The mechanism in question is centric fusion: A large pair and a small pair of acrocentric chromosomes fuse to form one large pair of submetacentric chromosomes. The oval nasal openings are rostrolaterally oriented. Infants may be hand-reared for short periods (around 3 weeks) and successfully reintroduced into either their original group or into an experienced group that has had visual and olfactory exposure to the infant while it was being hand-reared. Instead, it appears that associative learning of olfactory and visual cues from the dominant female by subordinates results in a psychological conditioning component to the neural and neuroendocrine mechanisms that suppress reproduction in nonbreeding females (Abbott et al., 1997). This taxon was traditionally thought to be a primitive lineage, from which all the larger-bodied platyrrhines evolved. The perineum, the skin over the sternum, and the ventral surface of the tail are devoid of hairs. Howler monkeys are basically deliberate quadrupedal climbers that always use their prehensile tail (with dorsoventral friction skin) to secure their movements. Local factors that affect bone remodeling include cytokines that promote bone loss (IL-1, TNF-α, osteoclast differentiation factor), cytokines that inhibit bone resorption (IL-4, IFN-γ, osteoprotegerin), colony-stimulating factors, prostaglandins, leukotrienes, nitric oxide, and growth factors (insulin-like growth factor, TGF-β). Ovulation number and litter size are related to maternal condition, with a higher average maternal weight for larger litters than for smaller litters (Tardif and Jaquish, 1997). Macaca fascicularis (cynomolgus macaque) and Macaca mulatta (rhesus macaque) have been used in permanent and transient MCAO models. View Callitrichids Research Papers on Academia.edu for free. Figure 2.5. An example of this has been the apparent ineffectiveness of studies in marmosets to predict success with the neuroprotectant NXY-059 [2]. Part II: the capillaries in the dermal ridges of fingers and palms in man and monkeys / A. Ikeda & N. Umeda -- Adaptations in the hands of cercopithecoids and callitrichids / W. Maier -- Joints and muscles of hands and paws / R. McN. Therefore, “nuclear” marmoset families are a stable housing condition as long as the original breeding pair remains intact, i.e. Hominoids are distinguished from cercopithecoids in having primitive nonbilophodont molars, larger brains, longer arms than legs (except in humans), a broader chest, a shorter and less flexible lower back, and no tail. Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae / ˌ s ɜːr k oʊ p ɪ ˈ θ ɛ s ɪ d iː /.Twenty-four genera and 138 species are recognized, making it the largest primate family. Drugs recommended for Callitrichidae, Victoria K. Baxter, ... Kelly A. Metcalf Pate, in The Common Marmoset in Captivity and Biomedical Research, 2019. Définition et Explications - Les Simiiformes, ou anthropoïdés (Anthropoidea) selon les auteurs, est un groupe de primates, et plus précisément, le groupe des singes et des humains. In addition, females form social hierarchies in which only the dominant female breeds. question. Lissencephalic species are also smaller making them easier to house, manage, and conduct experiments. These results parallel findings on laboratory rodents that have altricial young but may either develop … Symon and colleagues used this species to characterize the ischemic penumbra, specifically the relationships between time, blood flow, and the likelihood of cerebral infarction after middle cerebral artery occlusion (MCAO) [5]. Sole of the left foot of the common marmoset showing the epidermal ridges, the proximal plantar pads (ppp), the distal plantar pad (dpp), and the five digital pads (dp), one on each toe. Banding studies will be able to show whether homology exists between the arms of the submetacentrics and the autosomes from which they purportedly derive. University of Chicago 1977. Females produce one to three young annually. Superfamily cercopithecoid (plural cercopithecoids) Any species of the superfamily Cercopithecoidea (the Old World monkeys). However, this tuft of white hairs is not yet present in the neonatal animal (Fig. Crook et al. Group of primates that rely heavily on fruits 5 Primate dental morphology Includes adaptations … It is unfortunate that here the same terminology has been applied to lump together totally incompatible locomotor behaviors with completely incompatible locomotor morphologies. They do not leap, and are said to use their tails in bridging maneuvers between branches to allow their young to cross. Results of qPCR-based studies have determined that although chimerism can be detected across a variety of tissue types, levels are significantly higher in tissues derived primarily from the hematopoietic lineage, such as the bone marrow. 14.2 An owl monkey, ... 17.1 Female baboon with a sexual swelling, a recurring trait among cercopithecoids. As with other cooperative breeders, reproductive suppression in male marmosets appears to be predominantly behavioral rather than physiological. Alexander -- Muscle fibre and tendon lengths in primate extremities / G.P. Humans are catarrhines The Catarrhini are divided into cercopithecoids Old. Family Cercopithecidae (Old World monkeys) 2 subfamilies of 21 genera with 103 or more species, almost all from Asia and Africa. Although unproven, this difference may limit the capacity of stroke experiments conducted in lissencephalic species to predict the effects of a promising therapy in humans. Egozcue (1969), however, found that the chromosome morphology of C. goeldii also puts this species between Callitrichidae and Cebidae and placed Callimico into a separate family, Callimiconidae. Young are often carried on the parents' backs. The type species, Cercopithecoides williamsi, was named by O. D. Mollett in … If possible, allow owners to treat their pet at home, as they become depressed when separated from family members. PTH predominantly regulates serum calcium levels and is involved in both bone formation and resorption; 1,25(OH)2D is covered in more depth later in this chapter. Macaque monkeys (genus Macaca) have a gyrencephalic brain with cortical and subcortical anatomy similar to human. He reports that particularly the smallest monkey, Cebuella pygmaea, as well as the marmoset Callithrix jacchus, move about by using vertical clinging and leaping activities. Due to their size, Old World species require specialized housing facilities with larger cages and more environmental enrichment than the smaller New World species. The mouth opening is wide. question. Prehensile tail. Currently, the relationship between renal disease and atherosclerosis development in Callitrichidae is unclear. Social development during the first twenty weeks in the cotton-top tamarin (, "Some nomenclatural notes regarding authorship and dates of New World monkeys (Primates: Platyrrhini)", Marmosets and tamarins: dwarfed monkeys of the South American tropics, "Phenotypic evolution in marmoset and tamarin monkeys (Cebidae, Callitrichinae) and a revised genus-level classification", "Taxonomic Review of the New World Tamarins (Primates: Callitrichidae)", Learn how and when to remove this template message, https://en.wikipedia.org/w/index.php?title=Callitrichidae&oldid=996135316, Articles lacking in-text citations from June 2009, Creative Commons Attribution-ShareAlike License. Adaptations in the hands of cercopithecoids and callitrichids. Genera Ateles and Brachyteles are arboreal quadrupeds and habitually use the arms for suspensory activities. if a primate possesses molars with high shearing crests, they … Humans are catarrhines. Parental duties may include carrying, protecting, feeding, comforting, and even engaging in play behavior with offspring. Hi there! The primary hypothesis for detection of chimerism within nonhematopoietic tissues is infiltration by blood or lymphocytes [157]. 2.1). The tip of the tail presents a bunch of white-tipped black hairs [1] (Fig. Callimico. Marmosets are known to consume a considerable amount of tree exudates such as sap. Both tamarins and marmosets are diurnal arboreal quadrupeds that tend to eat insects, small vertebrates, and fruits. Most recently, however, quantitative PCR (qPCR) has been utilized to compare and quantify levels of chimerism between individuals as well as between tissue types within an individual animal. Based on the reported resistance of the Callitrichidae family to atherosclerosis in the wild, Dreizen and co-workers investigated whether a high cholesterol (5% w/w) – high lard (23% w/w) diet would be atherogenic in the cottontop tamarin (S. oedipus). Callitrichids are diurnal and live in family groups. Humans are catarrhines the catarrhini are divided. 2.3 versus 0.44 young/year for provisioned macaques) (Fedigan et al., 1986), it is considerably less than the oft reported maximum. Définition et Explications - Les Callitrichidae forment un groupe de singes miniatures parmi les singes du Nouveau Monde. fed four common marmosets monkeys (C. jacchus) an atherogenic diet containing 0.73 mg of cholesterol/kcal (0.34% wt/wt) for 11 months. Lactation lasts for 65–90 days and infants begin to take solid food at around 30 days of age and are completely weaned from milk at around 80–100 days of age. Cercopithecoidea (order Primates, suborder Simiiformes) A superfamily that comprises the extinct and extant monkeys of the Old World. Historically, the most common species used in stroke experiments has been the Papio anubis (baboon). Marmosets also have several adaptations that allow them to digest gums (Harrison and Tardif, 1994; Power and Oftedal, 1996). Three or four tactile hairs (vibrissae) can be observed on the supraorbital ridge. M. Tymianski, in Primer on Cerebrovascular Diseases (Second Edition), 2017. The Callitrichidae (also called Arctopitheci or Hapalidae) are a family of New World monkeys, including marmosets, tamarins and lion tamarins. As with both Damaraland and naked mole-rats, nonbreeders have reduced concentrations of plasma LH as a result of changes in secretion of, or sensitivity to, hypothalamic GnRH. They are the smallest of the simian primates. Subordinate males do have reduced plasma concentrations of LH and testosterone, but whether these deficiencies result in impaired spermatogenesis and quality and quantity of mature spermatozoa remains unclear. Although the lipoproteins of the Callitrichidae are similar to human lipoproteins in many ways, hypercholesterolemia is characterized by increases in the VLDL-C fraction whereas the LDL-C fraction is usually increased in hypercholesterolemic humans. Female marmosets display no overt signs of ovulation. answer. The vascular anatomy of the macaque closely resembles the human with less collateralization than the baboon [6]. Aggression between males and females is relatively uncommon, and establishing breeding pairs is straightforward. Palm of the left hand of the common marmoset showing the epidermal ridges, the six palmar pads (pp), and the five digital pads (dp), one on each finger. The marmoset nail on the hallux is probably advantageous in grasping, which plays an important role in the tree gouging and exudate feeding in Callitrichidae [3,7]. Infants may also be cross-fostered to families with only one infant of a similar age. Nigel C. Bennett, ... Jennifer U.M. These are more numerous on the digits [8]. fruit. They are generally smaller than Old World primates and exhibit less, lissencephalic, or near-lissencephalic brains. Owl monkeys Capuchins Squirrel monkeys. Do Callitrichids have long or short interbirth intervals? The bunch of white-tipped hairs on the ears is very typical. This postural behavior is the reason that Kinsey (1975) also attributed the locomotor category VCL to several of the small New World monkeys. Most have 4 metacentric chromosomes, 24–28 submetacentrics, and 10–18 acrocentrics in their diploid set. So, while the pace of marmoset reproduction is clearly faster than in larger-bodied Old World monkeys (e.g. Taxa included in Callitrichidae are:[10][11], Media related to Callitrichinae at Wikimedia Commons All the karyotypes of this family that are known have 2n = 44, 46, or 48. Among the macaques the cynomolgus may be more similar to humans in that it may have less collateralization than the rhesus as demonstrated by the need to occlude the ACA (​anterior cerebral artery) along with the distal middle cerebral artery (MCA) to produce a cortical stroke in the rhesus [3] versus clipping only the first segment of the MCA in the cynomolgus to produce an equivalent stroke [3]. What kind of … A recent examination of reproductive output in a population of around 400 dams found an average yearly production of weaned offspring of around 2.3 and a lifetime production of 7.75. The result of this phenomenon is genetically chimeric infants with tissues derived from embryonic cell lineages from self as well as from their sibling. However, recent field data have shown a high degree of variability in the callitrichid mating system (Sussman and Garber, 1987; Ferrari and Lopes Ferrari, 1989), with about 61% of wild social groups containing only one breeding female and multiple adult breeding males that help rear the infants. The body length is 14–18 cm and the tail measures 25–32 cm in length [4]. The hands of geladas show a suite of peculiarities which appear to be connected with their … Crook et al. However, none of these factors is implicated in social suppression of reproduction in common marmoset monkeys. Add extension button. Authors; Authors and affiliations; W. Maier; Chapter.
