“…That being said, however, the age range of female marmosets in our study was relatively restricted (4.5 – 8.7 years of age). These ages are not exceptionally old for a species in a genus ( Callithrix ) that can live to more than 16 years of age (Ross et al, 2007). …”

Maternal hormones can dramatically modify offspring phenotypes via organizational actions on morphological and behavioral development. In placental mammals, there is the possibility that some portion of hormones in maternal circulation may be derived from fetal origin. We tested the possibility that maternal androgens in pregnant female marmosets reflected, in part, contributions from male fetuses by comparing levels of urinary androgens across pregnancy in females carrying varying numbers of male offspring. We monitored urinary androgen excretion in 18 pregnancies from five female white-faced marmosets (Callithrix geoffroyi). Androgen levels rose significantly in the first trimester of pregnancy, reached a peak in the middle of the second trimester, and then declined gradually until parturition. At no point in pregnancy were levels of urinary androgens higher in females carrying litters that had 50% or more males than females carrying litters that were less than 50% male. Levels of maternal androgens were not associated with litter size, the number of males in the litter, or with the proportion of the litter that was male. The high levels of androgen in pregnant females are therefore likely of strictly maternal origin, and any modification of fetal growth and development can be considered a 'maternal effect'.

“…First, marmosets are the only simian primates that produces a litter. The modal litter size is two, but litter sizes can range from one to five (Smucny et al, 2004; Ross et al, 2007). Second, since the offspring are not identical twins, the sex ratios of litters can vary from 0% to 100% males.…”

“…The maximum lifespan for the marmoset is 16.5 years 3 ; reports indicate that the average lifespan of captive marmosets is 5 to 7 years (Abbott et al 2003; Dyke et al 1993; Ross et al 2007; Smucny et al 2004; Tardif et al 2003). Figure 1A illustrates postinfancy survival by age for 358 marmosets that were born in the Southwest National Primate Research Center (SNPRC) colony and survived to at least 0.5 years of age, between January 1994 and March 2010 (excluding those whose deaths were related to experiments).…”

The common marmoset (Callithrix jacchus) is poised to become a standard nonhuman primate aging model. With an average lifespan of 5 to 7 years and a maximum lifespan of 16.5 years, marmosets are the shortest-lived anthropoid primates. They display age-related changes in pathologies that mirror those seen in humans, such as cancer, amyloidosis, diabetes, and chronic renal disease. They also display predictable age-related differences in lean mass, calf circumference, circulating albumin, hemoglobin, and hematocrit. Features of spontaneous sensory and neurodegenerative change—for example, reduced neurogenesis, β-amyloid deposition in the cerebral cortex, loss of calbindin D28k binding, and evidence of presbycusis—appear between the ages of 7 and 10 years. Variation among colonies in the age at which neurodegenerative change occurs suggests the interesting possibility that marmosets could be specifically managed to produce earlier versus later occurrence of degenerative conditions associated with differing rates of damage accumulation. In addition to the established value of the marmoset as a model of age-related neurodegenerative change, this primate can serve as a model of the integrated effects of aging and obesity on metabolic dysfunction, as it displays evidence of such dysfunction associated with high body weight as early as 6 to 8 years of age.

“…Callitrichids have been maintained in captive colonies for many years and there has been considerable research investigating the factors that influence litter size and survivability of offspring [Jaquish et al, 1996;Rothe et al, 1982Rothe et al, , 1987Snowdon et al, 1985;Tardif et al, 2002;Windle et al, 1999]. In contrast to other nonhuman primates, callitrichids are unusual as litter size can vary between one to five offspring in captivity [Coimbra-Filho et al, 1984;Jaquish et al, 1996;Leong et al, 2004;Ross et al, 2007;Snowdon et al, 1985;Tardif et al, 1984a,b;Windle et al, 1999]. Although twins tend to be the norm for most callitrichids, the incidence of triplet and quadruplet births can account for nearly 10-50% of the litters born in captive colonies [Leong et al, 2004-S. oedipus;Ross et al, 2007-C. kuhlii;Windle et al, 1999-Callithrix jacchus].…”

Cotton-top tamains (Saguinus oedipus) are a critically endangered primate found only in Colombia. Efforts to conserve this species are centered on developing effective management plans that integrate biological information regarding population dynamics and factors that influence their survival. This study documented infants born to wild cotton-top tamarin females from 1994-2008 at two distinct field sites in northern Colombia. Our studies have shown that wild cotton-top tamarins typically give birth to one litter each year and infant survival to 6 months of age was greater in the wild than has been reported in captive colonies. However, similar to reports from captive colonies, litter size of wild cotton-top tamarins ranges from 1-3 infants, with twin litters most common. Here we report the first occurrence of triplet litters in nearly 20 years of observing wild cotton-top tamarin groups. Over the first 3 months of life, wild-born infants exhibited highest mortality during the first week of life, similar to reports from captive colonies. Infant survival in the wild also increases with successive litters as it does in captivity. However, inter-birth interval, group size, and the number of adult males in the group did not appear to influence infant survival in the wild. The value of such long-term data from field studies aids in the information that can be used to model future population trends and develop effective conservation plans for this critically endangered primate.
