Night monkeys (Aotus spp.) typically live in small family groups consisting of a monogamous pair and their offspring. These groups are highly cohesive, with strong bonds between members. Both parents are involved in raising the young, exhibiting cooperative breeding behavior.

Our findings showed different MT-CO1, MT-CO2, MT-CYB and SRY haplotypes between Aotus species although some SRY haplotypes differed by only one nucleotide (see Figure 2A), as was the case of A. infulatus (IN2) when compared to A. azarae boliviensis (AB1) and A. nigriceps(NI2). Identification based on MT-CO2was shown to be unreliable for closely rel...
Analyses of the different datasets showed that Dat-CO1 contained the highest number of PI sites (182), closely followed by Dat-CYB (181), while Dat-CO2, showed the lowest number (66). This might be related to the smaller size of MT-CO2 (696 bp) respective to MT-CO1 (1,557 bp) and MT-CYB (1,140 bp) although a similar number of PI sites was found in ...
Our phylogenetic reconstructions question the classical grouping of red neck and grey neck species proposed by Hershkovitz . All phylogenetic reconstructions based on mtDNA showed that the lineage leading to the grey neck species A. trivirgatus was a sister lineage of the one leading to the red neck clade (A. nigriceps (A. azarae, A. infulatus)). I...

A primary distinction between red-necked and gray-necked night monkeys is spatial distribution. Gray-necked night monkeys (Aotus lemurinus group) are found north of the Amazon River, while the red-necked group (Aotus azare group) are localized south of the Amazon River. [11]
Sep 14, 2023 · Aotus spp. serves as a remarkable nonhuman primate model, and researchers are particularly well-suited to integrate data from captivity and the field, due in great part to the extensive and well-habituated populations of owl monkeys at the DuMond Conservancy, OMBRR, and the Owl Monkey Project.
Aotus trivirgatus eat primarily fruits, insects, nectar and leaves. They will also complement their diet with lizards, frogs and eggs for protein. During times when food is scarce, they seek out mostly nectar, figs and insects.
Jan 31, 2012 · Owl monkeys Aotus spp have the potential to be a great model to accomplish a thorough integration of zoo and field research. Their most salient features are their nocturnal habits, monogamous social ...

Jul 18, 2005 · The Genus Aotus used to contain only one species (Aotus trivirgatus) with ten subspecies, but in 1983, all ten subspecies were elevated to species level and subsequent genetic work has refined the taxonomy even more (Groves 2001).
