riverine barriers and gene flow in amazonian saddle-back tamarins.	we describe patterns of genotypic and phenotypic variation in saddle-back tamarin (saguinus fuscicollis) populations along the central and upper rio juruá, western brazilian amazonia. the genetic data are sequence haplotypes of the mitochondrial cytochrome b gene; phenotypic data are pelage colour variants that define sharply demarcated subspecies of this extremely variable tamarin species. we show that gene flow occurs between adjacent subspecies, but that this phenomenon is restricted to the h ...	1996	9032947
anti-predation benefits in a mixed-species group of amazonian tamarins.	because of their small body size, tamarins are potentially vulnerable to a wide range of predator species. this paper examines the general patterns of predator avoidance of the avila-pires saddle-back tamarin (saguinus fuscicollis avilapiresi) and the red-cap moustached tamarin (saguinus mystax pileatus) in the upper urucu river, amazonas, brazil. one highly stable mixed-species group of these species suffered an average of 1 attack by carnivorous raptors every 8.8 days of activity. although non ...	1993	8188122
