Mar 13, 2024 · Meet the owl monkey, also known as the night monkey, the world’s only nocturnal primate species. What is an owl monkey and where do they live? The owl monkeys are a group of 10 species in the...
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...

Azara’s night monkeys, also called Azara’s owl monkeys and southern night monkeys, are endemic to the Gran Chaco region of South America—a large area including many diverse ecosystems, from grasslands to savannas to xeric thorn forests and gallery forests.
Apr 1, 2017 · Recently, however, we encountered for the first time de novo chromosomal alterations in hybrid individuals of night monkeys (also known as owl monkeys), a primate taxon of placental mammals. Night monkeys are a distinct genus ( Aotus) within the radiation of New World Monkeys (Platyrhinni).

Night monkeys are found in southern Central America through South America as far south as Bolivia, northeastern Argentina, and Paraguay. The genus Aotus is the second most widely distributed New World monkey genus, with howler monkeys being more widely distributed. (Cawthon Lang and Fernandez-Duque, 2005; Martin, 2004; Nowak, 1991)
