Microsatellite markers for woolly monkeys (Lagothrix lagotricha) and their amplification in other New World primates (Primates: Platyrrhini)

MOLECULAR ECOLOGY RESOURCES, Issue 2 2004
Anthony Di Fiore
Abstract Seven polymorphic microsatellite loci were identified for woolly monkeys (Lagothrix lagotricha) from an ,enriched' genomic library. For a wild population of 66 animals, these markers averaged over 10 alleles per locus and provided a combined probability for excluding a random individual from parentage of over 98%. These loci were screened in up to 13 other genera of New World monkeys, and many were variable in multiple taxa. Few other platyrrhine-specific microsatellite markers have been identified; thus, these loci should prove valuable for studying the population genetic structure and mating system not just of Lagothrix but also of other neotropical primates.

Arterial vascularization of the mandible and maxilla of neotropical primates

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 8 2006
Cristiane Schilbach Pizzutto
Abstract The objective of the present investigation was to conduct a comparative macroscopic study of the arterial vascularization of the mandible and maxilla of neotropical primates of the genera Cebus, Alouatta, Callithrix, and Leontopithecus. After vinyl was injected into the arterial system of the head of each specimen, the pieces were macerated and corroded. The level of the bifurcation of the common carotid artery into the internal and external carotids varied between the first and third cervical vertebrae. The external carotid artery accounts for most of the vascularization of the facial structures. The actual vessels responsible for the supply of this region are the sublingual, facial, angular, lingual, submandibular, submental, inferior and superior labial, maxillary, inferior alveolar, infraorbital, superior posterior alveolar, palatine major, and sphenopalatine arteries. We conclude that although the arterial vascular pattern was similar in all the genera studied, and resembles the human pattern, there are notable variations in the vasculature of the mandible and maxilla among these four neotropical genera.
