There is consensus (e.g., Szalay and Pleistocene Delson, 1979; Delson, 1980; Alba et al., 2011, 2014) that all the Eu- ropean fossil macaques belong to the lineage of the extant M. sylvanus. The two earliest (latest Miocene) European macaque records (Kohler€ et al., 2000; Alba et al., 2014) are attributed to cf. Macaca sp., while the macaque fossil remains from Sardinia are recognized as an extinct, endemic insular species, Macaca majori Azzaroli, 1946 (Zanaga, 1998; Rook and O'Higgins, 2005). The remaining fossil macaque remains from Europe, following Szalay 1.

  • Targets, Tactics, and Cooperation in the Play Fighting of Two Genera of Old World Monkeys (Mandrillus and Papio): Accounting for Similarities and Differences
    2019, 32 Heather M. Hill Editor Peer-reviewed Targets, Tactics, and Cooperation in the Play Fighting of Two Genera of Old World Monkeys (Mandrillus and Papio): Accounting for Similarities and Differences Kelly L. Kraus1, Vivien C. Pellis1, and Sergio M. Pellis1 1 Department of Neuroscience, University of Lethbridge, Canada Play fighting in many species involves partners competing to bite one another while avoiding being bitten. Species can differ in the body targets that are bitten and the tactics used to attack and defend those targets. However, even closely related species that attack and defend the same body target using the same tactics can differ markedly in how much the competitiveness of such interactions is mitigated by cooperation. A degree of cooperation is necessary to ensure that some turn-taking between the roles of attacker and defender occurs, as this is critical in preventing play fighting from escalating into serious fighting. In the present study, the dyadic play fighting of captive troops of 4 closely related species of Old World monkeys, 2 each from 2 genera of Papio and Mandrillus, was analyzed. All 4 species have a comparable social organization, are large bodied with considerable sexual dimorphism, and are mostly terrestrial. In all species, the target of biting is the same – the area encompassing the upper arm, shoulder, and side of the neck – and they have the same tactics of attack and defense. However, the Papio species exhibit more cooperation in their play than do the Mandrillus species, with the former using tactics that make biting easier to attain and that facilitate close bodily contact.

Results confirm that allometric scaling of craniofacial shape characterized by positive facial allometry and negative neurocranial allometry is present across adult papionins. Pairwise comparisons of regression lines among genera revealed considerable homogeneity of scaling within the Papionini, however statistically significant differ- ences in regression lines also were noted.

How an individual forms and maintains social bonds may be influenced by a large number of factors including sex, age, dominance rank, group structure, group demographics, relatedness, or seasonality. Individuals may employ differential social strategies both in terms of the type and quantity of interactions they engage in as well as their chosen social partners. The objective of this dissertation is to examine sociality in adult male Japanese macaques (Macaca fuscata) and the varying strategies that individuals may employ depending on their relative position within a social group.

  • 1 Old World Monkeys
    2003. 5. 23 Dr. Toshio MOURI Old World monkey Although Old World monkey, as a word, corresponds to New World monkey, its taxonomic rank is much lower than that of the New World Monkey. Therefore, it is speculated that the last common ancestor of Old World monkeys is newer compared to that of New World monkeys. While New World monkey is the vernacular name for infraorder Platyrrhini, Old World Monkey is the vernacular name for superfamily Cercopithecoidea (family Cercopithecidae is limited to living species). As a side note, the taxon including Old World Monkey at the same taxonomic level as New World Monkey is infraorder Catarrhini. Catarrhini includes Hominoidea (humans and apes), as well as Cercopithecoidea. Cercopithecoidea comprises the families Victoriapithecidae and Cercopithecidae. Victoriapithecidae is fossil primates from the early to middle Miocene (15-20 Ma; Ma = megannum = 1 million years ago), with known genera Prohylobates and Victoriapithecus. The characteristic that defines the Old World Monkey (as synapomorphy – a derived character shared by two or more groups – defines a monophyletic taxon), is the bilophodonty of the molars, but the development of biphilophodonty in Victoriapithecidae is still imperfect, and crista obliqua is observed in many maxillary molars (as well as primary molars). (Benefit, 1999; Fleagle, 1999) Recently, there is an opinion that Prohylobates should be combined with Victoriapithecus. Living Old World Monkeys are all classified in the family Cercopithecidae. Cercopithecidae comprises the subfamilies Cercopithecinae and Colobinae. Cercopithecinae has a buccal pouch, and Colobinae has a complex, or sacculated, stomach. It is thought that the buccal pouch is an adaptation for quickly putting rare food like fruit into the mouth, and the complex stomach is an adaptation for eating leaves.
