Lifetime reproduction
Tamarin’s typically live in extended family groups composed of anywhere between 4 and 15 individuals. Dominant female callitrichides suppress reproductive activity between their daughters and the other subordinate females of their family group. Ovulation among female tamarins typically occurs between 12 and 17 months whereas male tamarins Sperm production occurs slightly later in age at about 13 to 18 months. Although groups of tamarins may have more then one female in a group, only one of them typically breeds with the exception of the geodli’s monkey. Female callitrichids are able to conceive again in as little as 2-4 weeks after giving birth to their offspring. All callitrichids other than the callimico typically give birth to twins and are the only monkey known to do so. Saguinus niger infant births were observed in both early January and mid July.[1] Infants within the family group are generally carried by other group members whom feed them through weaning and juvenile growth. As infant tamarins mature, they reach independence at 5 months of age. Due to accelerated deforestation for agriculture, selective logging, and cattle ranching developments, the black tamarin is facing rapid population decline.[2] Some marmosets occupy small forest locations in the Tapajós and Madeira Basins but the black-handed tamarin is absent among these regions due to lack of food resources.The saguinus niger however, is considered to be more tolerant of habitat disturbances than other callitrichides.[1]
