can sometimes lead to infanticide by the mother. Conservation The population trend for the moustached tamarin monkey is decreasing; however, the IUCN red list categorizes the moustache tamarin as least concerned. They have demonstrated an ability to adapt to disturbed habitats and proximity to human settlements. They can acclimate well to changes in environmental conditions and their ecosystem. Habitat destruction remains an inevitable threat to their population as for all species living in the Amazonian rainforest. However, their ability to adapt gives hope that this factor will not severely affect their population numbers. Economic importance Moustached tamarin monkeys are economically significant because they are used extensively in biomedical research, like other tamarin species. They have been used in the development of the hepatitis A vaccine.
