There are no known negative affects on humans.
There are no known positive benefits to humans.
Their diet mainly consists of berries, fruits, seeds, roots, and plant stems. Little else is known about their food habits. (Parker 1990)
Macrotarsomys bastardi is found throughout southern and western Madagascar. (Anderson and Jones 1984, Nowak 1999, Parker 1990, Wilson and Reeder 1993)
Biogeographic Regions: ethiopian (Native )
Preferred habitats for M. bastardi are dry scrublands, dry deciduous forests, and grassland regions. (Wilson and Reeder 1993)
Terrestrial Biomes: savanna or grassland ; scrub forest
Macrotarsomys bastardi is the smallest species of the murid subfamily, Nesomyinae, the Malagasy mice. M. bastardi is similar in appearance to gerbils. Pelage color is brownish fawn on the upper body with a whitish underbelly. Body length ranges from 80 to 100 mm and tail length from 100-145 mm. The tail has a thin tuft of elongated hair at the end. The hind feet are rather large in comparison to body size and range from 22-28 mm long. Ears are from 22 to 25 mm long. The dental formula is 1/1, 0/0, 0/0, 3/3 = 16. Incisors are opisthodont and smooth faced. M. bastardi also has a weakly developed supraorbital shelf and moderately inflated auditory bullae. (Anderson and Jones 1984, Macdonald 1993, Nowak 1999, Parker 1990)
Range mass: 21 to 38 g.
Other Physical Features: endothermic ; bilateral symmetry
M. bastardi tend to live in pairs. This species is known to have 2-3 young per litter and to breed year round. Average gestation period is 24 days. In some studies females have bitten their mates to death. (Anderson and Jones 1984, Parker 1990)
Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual
The bastard big-footed mouse (Macrotarsomys bastardi) is a species of rodent in the family Nesomyidae. It is found only in Madagascar. Macrotarsomys bastardi is the smallest-bodied of the three species recognized within the genus Macrotarsomys.[2] Two subspecies have been recognized (M. b. occidentalis and M. b. bastardi) however 2004 studies did not find consistent differences between the subspecies and recommended "subspecific epithets be abandoned for this species".[2]
This is a terrestrial species, found primarily in xeric habitats such as dry deciduous forests in the northwest and spiny forests in the south.[2]
