High incidence of supernumerary nipples and twins in formosan macaques (Macaca cyclopis) at Mt. Longevity, Taiwan.
نویسندگان
چکیده
A population of Formosan macaques at Mt. Longevity exhibits an unusually high incidence of supernumerary nipples (polythelia: between 1-6 accessory nipples and/or areolae on 33% of adults), as well as a high rate of twinning (about 1% of births). The coexistence of these unusual traits suggests a connection, which is further supported by a tendency for mothers of twins to have accessory nipples and for twins to be born in troops with high incidence of polythelia.

Complete Taiwanese Macaque (Macaca cyclopis) Mitochondrial Genome: Reference-Assisted de novo Assembly with Multiple k-mer Strategy
The Taiwanese (Formosan) macaque (Macaca cyclopis) is the only nonhuman primate endemic to Taiwan. This primate species is valuable for evolutionary studies and as subjects in medical research. However, only partial fragments of the mitochondrial genome (mitogenome) of this primate species have been sequenced, not mentioning its nuclear genome. We employed next-generation sequencing to generate...

Mitochondrial DNA (mtDNA) polymorphisms in four species of macaques, i.e., Japanese monkey (Macaca fuscata), rhesus monkey (M. mulatta), Formosan monkey (M. cyclopis), and crab-eating monkey (M. fascicularis), were analyzed to study phylogenetic relationships. When 17 restriction enzymes of 6-bp recognition were used, 42-49 sites were observed in the samples. The estimated number of nucleotide ...

Feeding-related agonism among wild female Taiwanese macaques was investigated in two study groups at ecologically diverse sites (Fu-shan and Ken-ting) to determine whether contest-feeding competition was present in these groups. Females that contest for food within a primate group are hypothesized to form dominance hierarchies and tend to be philopatric. In this study we tested 1) whether Taiwa...

The classification of the Mm. levatores costarum in man into the same system as the M. intercostalis externus by L u s c h k a, E i s l e r, Nish i, etc. has been widely accepted. Recently F u j i t a who examined the nerve supply to these muscles reported that the view of Morrison with respect to the nerve supply was correct, and that these muscles are part of the intrinsic dorsal musculature ...
