“…The hormonal response of caretakers was not related to age Schradin and Anzenberger, 2004;Schradin et al, 2003). Moreover, some authors have associated glucocorticoid cortisol with parental response (black tufted-ear marmosets: Nunes et al, 2001; cotton-top tamarins: Ziegler et al, 2004) and prior experience raising young (cotton-top tamarins: Ziegler et al, 1996; black tufted-ear marmosets: Nunes et al, 2001).…”

“…In cotton-top tamarins, estradiol may play a role in promoting paternal care (Ziegler et al, 2004; see also Trainor and Marler, 2002). An association between prolactin levels and paternal and alloparental care has been investigated in birds (Garcia et al, 1996;Schoech et al, 1996), rodents (Gubernick and Nelson, 1989;Brown et al, 1995), New World primates (Dixson and George, 1982;Ziegler et al, 1996;Mota and Sousa, 2000), and humans (Storey et al, 2000;Fleming et al, 2002), showing an elevation in prolactin levels among animals participating in infant care. Among callitrichids, prolactin levels increases following infant carrying (common marmosets: Dixson and George, 1982;Mota and Sousa, 2000;Roberts et al, 2001).…”

The physiological mechanisms of parental and alloparental care in cooperatively breeding nonhuman primate species such as the common marmoset (Callithrix jacchus) are poorly known. In this study, we examined prolactin and cortisol plasma levels of fathers and older offspring of both sexes, with and without previous experience in infant carrying, around parturition and during infant carrying. Blood samples were collected from fathers and older offspring and prolactin and cortisol were measured by RIA and EIA, respectively. Prolactin levels of both caretakers were not influenced by infant's birth, previous experience or proximity to parturition. However, prolactin levels increased in both caretakers while in physical contact with infants and also with the number of infants being carried in older offspring. These findings suggest that increased prolactin seems to be mainly due to physical effort rather than a physiological trigger of paternal and alloparental care in common marmosets. Cortisol levels were higher for experienced fathers shortly before parturition which could act to reinforce affiliative bonds between breeding males and females at this time or in the ability of males to detect the proximity of the parturition or both.

“…Serum and urine were collected during spontaneous and GnRH-induced LH surges, which were clearly identified in serum, but not in urine. By contrast, this antibody has proven effective in measuring LH concentrations in urine of other species, including callitrichids (Ziegler et al, 1993(Ziegler et al, , 1996, bottlenose and white-sided dolphins (Robeck et al, 2005), killer whales (Robeck et al, 2004), giant pandas (Kersey, Monfort, Brown, unpubl. ), manatees (Iske, Brown, unpubl.…”

“…The use of Centricon centrifugal filtration tubes to concentrate urine before protein hormone analysis was based on studies conducted in primates (Schradin et al, 2003;Keely and Faiman, 1994;Ziegler et al, 1996). Following essentially the same protocol, using tubes that concentrated urine $6-to 10-fold, we failed to observe changes in urinary prolactin or LH immunoactivity that correlated with serum concentrations.…”

“…Both LH and prolactin are excreted in urine of humans and nonhuman primates and can be quantified using standard immunoassay techniques (LH -Miller and Soules, 1996;French et al, 1999: prolactin -Miller andSoules, 1996;Soltis et al, 2005;Schradin et al, 2003;Ziegler et al, 1996).

Measurement of scrotum and testis size of unrestrained captive cotton-top tamarins (Saguinus oedipus oedipus)

Reproduction is restricted to a small number of animals within both captive and wild groups of callitrichid monkeys (marmosets and tamarins). Sexual development of nonbreeding group members might differ from that of active breeders. Measurements of physical growth typically involve animal handling. However, capture and restraint of callitrichid monkeys can disrupt natural behaviors and physiology. This study introduces a method for estimating size of external genitalia by measuring frontal scrotum width of unrestrained cotton‐top tamarin males. We examined whether scrotum width was a reliable indicator of testis size, and whether the method provided information useful for comparisons of growth and development among individuals. Animals were lured to a standardized position, and maximum width of the scrotum was systematically compared to a card with a series of rectangles graded in 1 mm increments. Card measures were validated with caliper measurements of scrotum width and testicle dimensions. Regressions of testes dimensions measured by caliper on scrotum width measured by card were between 82 and 93%, suggesting that measures of frontal scrotum width provide consistent estimates of relative testis sizes. The period of rapid growth ended by roughly two years of age, after which scrotum size did not differ from that of breeding males. Am. J. Primatol. 51:187–195, 2000. © 2000 Wiley‐Liss, Inc.
