Stripe-backed Weasel (scientific name: Mustela strigidorsa) is also known as Stripe-backed Weasel or Back-striped Weasel in foreign languages. Its size and body color are similar to those of the yellow-bellied weasel, and it has no subspecies.
Stripe-backed Weasel may be a diurnal species, mostly acting alone. They mark their territories with scent, which also serves as an intraspecific communication mechanism to maintain territoriality. They probably have different sexual ranges, with males having significantly larger territories than females, and territories of conspecifics of the opposite sex often overlap.
Little is known about the dietary habits of the weasel. One prey species is the bandicoot. Weasels attack it by biting the nose. Weasels forage around dead wood, checking cracks and holes for insects, grubs, and worms inside dead wood. Weasels have also been documented hunting and capturing other rodents near streams.
Little is known about the reproductive behavior of the weasel. It is not known whether this species has delayed implantation, a reproductive trait that is not uncommon in mustelids. Most other species of the genus Mustela breed seasonally, usually for 3-4 months. Delayed implantation is required, and it may take up to 10 months for a fertilized embryo to implant in the species' uterus. Environmental conditions such as temperature and day length determine when implantation occurs. Mustelids living in more seasonal climates are more likely to have delayed implantation. After implantation, gestation usually lasts 30-65 days. Females give birth to one litter per season. The pups are altricial, born small and blind, and reach sexual maturity between 8 months and 2 years after birth.
The spotted mustelid has no significant conservation needs. The rate of habitat decline is fairly low, as it is found in degraded and fragmented forests, and has a high proportion of its numbers in mountainous and montane areas with relatively low rates of forest conversion. In addition, it is not targeted for collection markets, except for the fur market in China. The species has been included in many planned protected areas throughout its range. Many of these reserves have protection measures to prevent hunting and small-scale habitat loss, and the main conservation concern for the species in the long term may be the risk of inadequate actual security of declared protected areas.
Listed in the IUCN Red List of Threatened Species in 2015 ver 3.1 - Least Concern (LC).
