Genetic variability in four Alouatta species measured by means of nine DNA microsatellite markers: Genetic structure and recent bottlenecks
We used microsatellite DNA to study the population genetics of 4 Alouatta species from Central and South America. Our main findings include the following: (1) A. seniculus had the highest level of microsatellite variability while A. caraya and A. palliata had the lowest mean number of alleles per lo...
