Outline:
- 10 species, 33 subspecies (1977)
- 2 claids based off dental measurements (1992)
- 15 species, no subspecies (Rylands, 2000)
- Live of both banks of the Tocantins river
- S.niger and S. medas are monofiletic (common anncestors), those two are closest related based of mitochondrial DNA
- The differences between the different banks is as great as the difference between S. Midas and S. nigers
- Suggests that the Tocantins river is a gene flow barrier
Taxonomy:
The first ever classification of the Saguinus tamarins contained ten different species, and then further divided up into 33 morphotypes based on facial pelage. (Hershkovitz,1977) Then sixteen years after the first classification, (Found in Tocantins River As An Effective Barrier To Gene Flow In Saguinus Niger Population, Natori and Hanihara,1992) Natori and Hanihara came up with a new way to classify the Saguinus tamarins based on variations in dental measurements. Based off of the dental measurements they were broken into two clades. (1992) After the two clades based on dental measurements, Rylands presented a new way to classify the Saguinus tamarins. He broke them up into fifteen species with no sub species. This is the most recent classification. [1] The S. Niger has been discovered on both banks of the Tocantins. The S.Niger and S.Midas are common ancestors, it has been found that the S. Niger were more closely related based off of mitochondrial DNA, to the S. Midas on the other side of the river on the bank of Uatuma. [2]Which reveals that the river has created a divide between the two different populations of S. Niger on opposite sides of the Tocantins river. The difference between the two populations of the S. Niger is as great as the distance of the river between them. The river has created a gene flow barrier. [3]
