[9] It is assumed that like other nocturnal species, the reddish-gray mouse lemur has very sensitive ears, making them important for communication, social encounters, predator avoidance, and critter finding.
[10] Habitat type and factors, and genetic distance have both been found to be uncorrelated to the different pelage, and thus, they have little to not impact on the fur color of the individuals.
[10] Even though their perception of color is different from human beings, vision is still important to the reddish-gray mouse lemur as they may recognize one another from facial patterns.
[10] Like many other species in their suborder, the reddish-gray mouse lemur have tapetum lucidum, a characteristic that makes it easier for them to navigate in environments with low light levels.
Research has found that the morphology of their hands and feet may vary slightly depending on the individual's habitat due to the difference in tree types.
Individuals in the from the gallery forests, which have an abundance of small, flexible and high canopies, with many horizontal adjacent branches will have hook-like hands for easier locomotion.
The spiny forests have harsh and unpredictable conditions, with highly variable ambient temperatures, as well as scarce food and water sources compared to the other habitat types.
[15] During the drier regions or seasons, the reddish-gray mouse lemur will consume more gums and other plant exudates than other parts of their diet, such as fruits,[13][16] since they are more renewable and more readily available under these conditions.
A research on mouse lemur reproduction showed that estrus period seem to occur more often around October (though the number of females experiencing it may vary monthly and yearly).
The reproduction process may also involve mate-guarding, and alloparenting in female pairs since estrus may not be synchronous, but lactation may occur simultaneously, easing alloparental care.
[17] An example of this would be that females reddish-gray mouse lemur have been observed to have higher priority than their male counterpart when it comes to food resources, especially if they are scarce.
[10] However, despite their mostly solitary nature, communication and social signaling between individual mouse lemur still occur through auditory and olfactory means.
[15] Because of the unpredictability and challenges of their habitat, the reddish-gray mouse lemur has developed flexibility in their energy-saving tactics: torpor and prolonged hibernation.
[20] The length of the torpor, and the level of variation in thermal physiology also vary a lot between different individuals, even if they were to live in the same regions.
[1] Due to the high amount of anthropogenic disturbances occurring at their habitat, the resources the reddish-grey mouse lemur needs is often cut often.
