Conservation Habitat and Distribution: Marmosets and tamarins are found primarily in the tropical rainforests of South America with a few remnant populations located in Central America. The common marmoset is distributed throughout the Atlantic Coastal Forest of northeastern Brazil. Translocated populations of the common marmoset also flourish in the ranges of other Brazilian marmoset and tamarin species, such as around Rio de Janiero, well beyond their native coastal forests. The home range of a marmoset group can vary from 5,000 to 65,000 square meters (1.2-16 acres). On any one day a marmoset group will travel about 500 to 1000 meters. The common marmoset is entirely arboreal (tree dwelling) and prefers secondary or disturbed forests and edge habitat. This species may also be found in coastal and upland scrub forest, gallery forests and even gardens and parks of South American cities, such as Natal and Joao Pessoa. Wherever they are found, their home range will typically include a variety of habitat types.

Home Mammal Index Lecture Notes Legal Considerations ... Endangered Species Mammal Lab The mammals represent the highest adaptive level of the vertebrate plan of organization. The ultimate basis for their success as a group is the high degree of efficiency achieved by their homeostatic mechanisms, largely as the result of the culmination of certain morphological, physiological, and behavioral trends initiated at lower levels of vertebrate organization and improved by the lines leading to the mammals. This exercise will serve as an introduction to the structure of mammals as a background for a better understanding of their classification and biology. It will also afford an excellent opportunity to review many of the general trends that have occurred within the vertebrates. External Morphology Obtain a specimen of the albino rat or mouse. The albino rat is a laboratory strain of the Norway or brown rat ( Rattus norvegicus ), a species that has been widely introduced around the world. The albino mouse is a laboratory strain of the House mouse ( Mus musculus ) also with worldwide distribution.
