“…These differences in postnatal maternal effort may account for why C. goeldii infants grow at faster rates than do C. jacchus infants from birth to 18 months. More rapid infant and juvenile growth can explain why C. goeldii have been reported to reach sexual maturity faster than other callitrichids (Dettling and Pryce 1999).…”

“…C. goeldii offspring grow at faster rates than C. jacchus infants and juveniles, implying the retention of a callitrichid growth pattern apparently abetted by the production of only a single infant. This may explain why C. goeldii are reported to reach sexual maturity faster than C. jacchus in captive populations (Dettling and Pryce 1999).…”

Maternal care and infant development in Callimico goeldii and Callithrix jacchus

et al. 2010

Callimico goeldii gives birth to single offspring, whereas other callitrichids, including Callithrix jacchus, twin. This study compares maternal effort and infant development in C. goeldii and C. jacchus; it is the first study to look at nursing frequency. Infants were observed from birth for 7 weeks in two captive groups each of C. goeldii and C. jacchus. C. goeldii mothers physiologically invested the same or less than C. jacchus mothers. C. goeldii mothers gained the same amount of weight during pregnancy in absolute terms as did the smaller C. jacchus. This results in a smaller gain in proportion to maternal weight but an equivalent proportional gain on a per fetus basis. C. goeldii mothers nursed their infants less based on duration of nursing bouts compared with C. jacchus mothers. C. goeldii mothers transported their infants exclusively through the first 2 weeks of life, which is longer than C. jacchus mothers, who exclusively transported infants only during the first week of life. As maternal infant carriage declined, other group members transported offspring in both species. C. goeldii infants engaged in independent locomotive sequences later in development and tasted solid foods less frequently than C. jacchus infants when compared at equivalent ages. A single, opportunistic milk sample obtained from a C. goeldii mother when her infant was 48 days old indicates that C. goeldii milk contains gross energy from crude protein within the range of variation observed in Callithrix milk. Despite the similarities in milk quality and prenatal effort in individual fetuses, C. goeldii infants gain weight faster from 0 to 18 months than do C. jacchus infants. A reduction in litter size allows C. goeldii mothers to spend more time carrying their infant and to delay weaning, thereby allowing accelerated infant and juvenile growth rates compared with C. jacchus.

“…Although it shares many characteristics with other callitrichids, such as its small body size and claw-like nails, Callimico goeldii retains its third molar, and has singleton births, unlike most other habitually twinning callitrichids (Dettling and Pryce 1999;Hershkovitz 1977). It inhabits the western Amazonian basin of Perú, Brazil, Colombia, and Bolivia (Emmons and Feer 1997).…”

Distribution and New Sightings of Goeldi’s Monkey (Callimico goeldii) in Amazonian Perú

et al. 2012

There is a general consensus on the geographic distributions of many primate species; however, the continuity and validity of species range maps are often inaccurate on a local scale. In the case of rare and cryptic species, census methodology is often insufficiently rigorous or specialized, resulting in probable false negatives. Callimico goeldii is a rare primate, with most of its geographical range purported to lie in Perú. We evaluate the accuracy of its predicted geographic range within Perú with an assessment of mammal surveys over the last 40 yr and the inclusion of new sightings from three sites. We found that of all 340 study sites, only 10.9 % indicate that this species is present, and only 51 % of these sites receive any government protection. The Sierra del Divisor Reserve Zone and the Rodal Tahuamanu Conservation Concession have the highest estimated densities of Callimico goeldii. We suggest using focal follows of sympatric tamarins and vocalization playbacks rather than traditional line transects to improve the likelihood of locating this species. Although the current range maps based on the available data are likely an exaggeration of the species' true range, the inherent imperfections of standard census methodology when applied to rare and cryptic species can lead to underrepresentative range maps as well. For these reasons, it is clear that the current Int J Primatol

“…In common marmosets, the onset of sexual maturation in females is confirmed by the increase of sex steroids and identification of progesterone metabolites in urine (Dettling and Pryce 1999) or progesterone in plasma (Abbott and Hearn 1978). The social relationship dynamic among common marmoset females includes certain behavioral mechanisms, such as intrasex aggression, mate guarding and harassment during mating events, infanticide, and inadequate alloparental care.…”

Possible organizational effect of sex steroids on the stabilization of manual preference in female common marmosets (Callithrix jacchus)

2011

Handedness has been widely studied in nonhuman primates. However, few studies investigate this behavior throughout ontogenetic development. To determine the influence of developmental stage in common marmoset (Callithrix jacchus) females, we used six animals, which were observed in food-reaching tests involving hand-use preference from the infantile to the adult phase. During this period, fecal samples were collected for sexual hormone analysis (estrogen and progesterone). The results point to correlations between age and stabilization of manual preference across the developmental phases. A relationship between progesterone and the intensity of hand use asymmetry was observed during the pubertal period, when the data was grouped into three phases: prepubertal, pubertal, and postpubertal. These data show increasing strength of hand preference during ontogenetic development and that sexual hormones may be involved in females.
