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]
Night monkeys (Aotus), also known as owl monkeys, are New World primates found across Central and South America, ranging from Panama to northern Argentina. Belonging to the family Aotidae, they are characterized by their nocturnal lifestyle and distinctive owl-like appearance.

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...

The night monkey genus, Aotus, includes at least twelve species and three subspecies. ANDEAN NIGHT MONKEY. Aotus miconax. CONSERVATION STATUS: ENDANGERED. Andean night monkeys, also known as Peruvian night monkeys, are endemic to the South American country of Peru, in the Andes Mountains.
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.
Sep 14, 2023 · We identified 741 primates for sale, of which 33 (4.5%) of these were owl monkeys, all recorded as Aotus sp. During the “complete” survey at the Bellavista market, 4,063 primates were offered for sale across 14 stalls, including 63 (1.6%) owl monkeys, of which 41 were sold during the survey period.
May 21, 2024 · Owl monkeys, which comprise the genus Aotus and are also known as night monkeys, are of considerable scientific interest as they are the only simians with a nocturnal lifestyle evolved secondarily from a diurnal ancestor (Ankel-Simons and Rasmussen 2008).
