In this study, we identified OR gene repertoires in orangutans, marmosets, and mouse lemurs for the first time based on currently available genome sequences.
Coquerel's giant mouse lemur is thought to opportunistically prey on mouse lemurs after an individual was found with a half-eaten gray mouse lemur (M. murinus) in a trap.
Unlike Grandidier, they placed their specimen in the genus Microcebus (mouse lemurs); however, these authors also listed all Cheirogaleus under Microcebus and based the classification of their species on similarities with the greater dwarf lemur (M. typicus, now C. major).
A rejection of a peripatric model for mouse lemurs is also similar to a recent study on mantellid frogs based on range overlap analysis, where the authors found that range size differences among sister species increased with evolutionary age [ 67].
Later, it was recognized that Coquerel's giant mouse lemur was found in lower densities than the northern giant mouse lemur.
Resulting centroid sequences were used for downstream phylogenetic analyses based on sequences specific to the lemuriform families Cheirogaleidae (the dwarf and mouse lemurs) and Lemuridae (the true lemurs).
In a previous study it was shown that gray mouse lemurs seem to prefer to use their mouths to pick up raisins, but this was based on a small sample size (N = 8; [ 32, 33]).
Further, we did not find any influence of body posture on the direction or strength of hand preference in gray mouse lemurs, supporting previous findings in mouse lemurs for the comparison of the sit versus biped task, based on a small sample size [ 10].
Based on this total set of evidence, we diagnose 16 population-level lineages of mouse lemurs (Tables 2, 3).
Most surprising were the mouse lemurs, a group which is now thought to contain cryptic species, meaning they are indistinguishable from each other based solely on appearance.
