Mar 13, 2024 · Image credit: Edwin Butter/Shutterstock.com. Just once in a while, zoologists like to combine the names of animals – something like the parrotfish or the dragonfly. This time, they’ve done it ...
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]

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 mesmerizing beauty of lionfish blends seamlessly with coral formations beneath tropical waves, whereas tigerfish gracefully navigate through freshwater ecosystems displaying sheer strength through their distinctive stripes.
Sep 14, 2023 · In this chapter, we synthesize data from anatomy, neuroscience, psychophysics, genetics, and behavioral ecology to review the key adaptations of the owl monkey visual system for dim light vision. First, we review Aotus evolutionary history and highlight the dramatic variation available in light environments at night.
Sep 14, 2023 · Genetic data have firmly established that Aotus is more closely related to the cebid primates (capuchins, squirrel monkeys, marmoset, and tamarins) than to the pitheciids (sakis, uacaris, and titis), despite showing remarkable morphological and behavioral similarity to certain members of the latter clade.

Monkey and Tiger are both members of the animal kingdom, but they have many differences in terms of physical appearance and behavior. Monkeys are known for their agility and playful nature, often swinging from trees and interacting with their surroundings in a curious manner.
