Abiotic Factors which Affect the marmoset:
->Daylight: With shorter daylight they were active during twilight, with longer daylight they had a sleep phase during late morning.
->Background noise: With higher background noise the twitter call of the marmosets was higher as they amplified their vocals, with lower background noise the twitter call was of average pitch.
->Temperature: With higher temperature (40 degrees) activity is less and sleep hours longer. With normal temperature (around 28 degrees) Marmoset do usual activity and sleep regularly. With low temperature (under 15 degrees) marmoset have same activity and sleep hours as with high temperature.

Fun Facts:
1."Marmoset" is derived from the French "marmouset" which means, loosely, shrimp or dwarf. An apt name, considering they are the smallest of the true monkeys (the lightest of the true monkeys is the pygmy marmoset).
2.These monkeys use their specialized claws to establish a firm grip on tree trunks and gnaw little holes in the bark with their lower incisors and canines. This causes the tree to produce more sap, which is used to seal injuries to the bark. This tree sap is a valuable source of carbohydrates and minerals.
3.Common marmoset is considered the best species able to adapt to human changes in their environment.
4.The species was first introduced by humans in southeastern Brazil where it has propagated so successfully it is regularly observed in the marginal park districts of Rio de Janeiro.
5.Marmosets live in mixed sex groups of up to 13 individuals. Only the head male and female will produce offspring. The mechanism that supposedly suppresses reproduction in lower-ranking females is still being studied.
6.The differences between monkeys and apes are easy to see once you know what to look for. Apes do not have a tail and are generally larger than most other primates. They have a more upright body posture as well. Apes rely more on vision than on smell and have a short broad nose rather than a snout, as Old World monkeys do.
7.Old World monkeys are generally from Africa and Asia while New World monkeys are from the Americas. In Old World monkeys, the nostrils face downward and are narrow. New World monkeys have round nostrils facing to the side. Old World primates are usually larger than New World's. Many of the Old World monkeys are partly terrestrial.
8. Though no wildlife agency has listed the marmoset as endangered or threatened, they may be both! Unfortunately, there is no reliable way to count how many marmosets exist in the wild. Because of their size, color, and ability to blend into number of environments, it is hard to known how many currently exist. Marmosets' main threats are bird predators and human trappers.
