Impending extinction crisis of the world’s primates: Why primates matter
TLDR
Raising global scientific and public awareness of the plight of the world’s primates and the costs of their loss to ecosystem health and human society is imperative.
Sleeping habits of tamarins, Saguinus mystax and Saguinus fuscicollis (Mammalia; Primates; Callitrichidae), in north-eastern Peru
The sleeping habits of moustached tamarins, Saguinus mystax, and saddle-back tamarins, Saguinus fuscicollis, were studied in northeastern Peru. Five types of sleeping sites were distinguished: 1)
Long-term patterns of sleeping site use in wild saddleback (Saguinus fuscicollis) and mustached tamarins (S. mystax): effects of foraging, thermoregulation, predation, and resource defense
TLDR
Seasonal changes in photoperiod accounted for a significant amount of variation in sleeping site entry and exit times, and predation risk was indicated as the major factor influencing the pattern of sleeping site use in these species.
Paternity and kinship patterns in polyandrous moustached tamarins (Saguinus mystax).
We studied patterns of genetic relatedness and paternity in moustached tamarins, small Neotropical primates living in groups of 1-4 adult males and 1-4 adult females. Generally only one female per
Primates in Peril: The World's 25 Most Endangered Primates 2008–2010
TLDR
The 2016–2018 list of the world’s 25 most endangered primates has five species from Africa, six from Madagascar, nine from Asia, and five from the Neotropics.
Effects of logging, hunting, and forest fragment size on physiological stress levels of two sympatric ateline primates in Colombia
TLDR
Spider monkeys showed elevated glucocorticoid metabolite levels in forest fragments with high levels of human impact, whereas howler monkeys did not, providing evidence that hunting and logging can impose stress on animals.
Characterization and Social Correlates of Fecal Testosterone and Cortisol Excretion in Wild Male Saguinus mystax
TLDR
The data suggest that reproductive competition in moustached tamarins is not based on endocrinological, but instead on behavioral mechanisms, possibly combined with sperm competition.
Scent marking strategies of new world primates

  • 1 June 2006
TLDR
This paper reviews recent findings on scent‐marking behavior in wild New World primates and examines three functional hypotheses: territoriality, regulation of social and reproductive dominance, and mating competition/mate attraction to suggest a hypothesized function in intrasexual competition and intersexual mate choice.
