Geographic Range

Atherurus macrourus (Asiatic brush-tailed porcupines) are distributed across southeast Asia. They are found in Cambodia, Indonesia, Laos, Malaysian Peninsula, Malacca by Lyon, eastern Assam (India), Hupei, Hainan, southcentral China (Yunnan, Szechuan, and Guangxi provinces), Sumatra, Burma, Myanmar, Thailand, Vietnam, and adjacent Indo-chinese islands. (Asian Regional Centre for Biodiversity Conservation, Various National Biodiversity Conservation Units (NBRUs), and European Partner Institutions, 2004; Corbet and Hill, 1991; Grzimek, Schlager, and Olendorf, 2003; Wilson, 1993)

Biogeographic Regions:
oriental (native ); oceanic islands (native ).

Habitat

Elevation
3000 m (high)
(9840 ft)


Asiatic brush-tailed porcupines are terrestrial and nocturnal. They rest during the day in burrows, crevices, termitaries, under and in fallen trees, in holes among tree roots, caves, or cavities along stream banks. They can live in elevations up to altitudes of 3000 meters. Asiatic brush-tailed porcupines prefer to live by plantations or cultivated areas, river forests, forest islands, as well as primary and secondary forests. These animals may dig burrows in soft floors of rainforests, and are often found near water. Rock dens are found to be intricate, having three entries spaced 2 meters apart, feeding into tunnels 3.5 meters long, showing that species of hystricids can be productive lodge diggers. Asiatic brush-tailed porcupines do not cushion their dens with plant materials. (Asian Regional Centre for Biodiversity Conservation, Various National Biodiversity Conservation Units (NBRUs), and European Partner Institutions, 2004; Gould, McKay, and Kirshner (Illustrations), 1998; Grzimek, Schlager, and Olendorf, 2003; Storch and Parker (Editor), 1990; Wilson, 1993)

These animals are found in the following types of habitat:
tropical ; terrestrial .

Terrestrial Biomes:
forest ; rainforest ; scrub forest .

Other:
agricultural ; riparian ; caves.

Physical Description

Mass
1 to 4.30 kg
(2.2 to 9.46 lbs)


Length
36.50 to 60 cm
(14.37 to 23.62 in)


Asiatic brush-tailed porcupines are rat-like and quite slender. They have an almost entirely spiny body, though quills are soft on the under parts, head, and legs. Fur coloration on the upper back is black-brown to grey-brown. These animals possess short and stout limbs, with short, rounded ears. Eyes and ears are quite small. Individual hairs have whitish tips. The underside (ventral side) fur coloration is dirty white to light brown. Their roundish spines are flattened and stiletto-like, with fluted grooves on the upper surface. On the lower back, round and thicker bristles are interspersed between the spines resulting in a distinct terminal tuft. The tuft is whitish to creamy buff in color. Each bristle is thick and scaly and contains a chain of flattened disks that rattles when shaken. This serves as a warning to deter predators. On the upper back, flexible spines are between the fluted spikes, and the longest spines are located on the mid-upper side region. Spines can be about 10 cm long. They have a brush-like tuft on the tip of the tail.

These animals are agile and can run, climb, and swim well. Their fore- and hind-feet are five toed, partially webbed and possess blunt, straight claws. However, the large toe is reduced. The soles are naked and are fitted with pads. The skull lacks or has a very weak postorbital process. (Asian Regional Centre for Biodiversity Conservation, Various National Biodiversity Conservation Units (NBRUs), and European Partner Institutions, 2004; Gotch, 1979; Gould, McKay, and Kirshner (Illustrations), 1998; Grzimek, Schlager, and Olendorf, 2003)

Some key physical features:
endothermic ; homoiothermic; bilateral symmetry .

Reproduction

Breeding interval
Females give birth to 1 to 2 litters per year.

Breeding season
Breeding occurs throughout the year in regions with more favorable climates, and during the most favorable season in more temperate regions.

Number of offspring
1 to 2

Gestation period
100 to 110 days

Time to weaning
2 months (average)

Time to independence
1 to 2 years

Age at sexual or reproductive maturity (female)
2 years (average)

Age at sexual or reproductive maturity (male)
2 years (average)

The spines on the backs of females can make mating problematic for male brush-tailed porcupines. Females can be aggressive and rapidly move backward into a male (backward attack). African brush-tailed porcupine (Atherurus africanus) females are not aggressive toward males they are familiar with, but are very aggressive when meeting unfamiliar males. Therefore, a complicated ritual of appeasement performed by males. In other members of the genus Hystrix, the female puts her tail up and the male stands on his hind legs, supporting himself with his hands on the back of the female during mating. (Storch and Parker (Editor), 1990)

Mating systems:
monogamous .

Both parents participate in raising the young. They breed throughout the year in regions with more favorable climates, otherwise breeding seasonally in the most favorable season. They have 1 to 2 litters a year, with 1 to 2 offspring per litter. No information was found concerning the gestation period of this species, but the related Atherurus africanus has a pregnancy that lasts 100 to 110 days. Females have two pairs of lateral thoracic mammae, and give birth in maternity chambers cushioned with grass or fallen leaves.

Key reproductive features:
iteroparous ; seasonal breeding ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous .

Newborns are very active and agile within hours after they are born. They are highly developed nidifugous animals, with eyes open soon after birth. Because they are very small in size, (3% of the mother's body weight) they have to be nursed for a long time. Both parents participate in guarding the young, taking them for their first excursions and watching over them. (Storch and Parker (Editor), 1990)

Parental investment:
precocial ; pre-fertilization (provisioning, protecting: female); pre-hatching/birth (provisioning: female, protecting: male, female); pre-weaning/fledging (provisioning: male, female, protecting: male, female); pre-independence (provisioning: male, female, protecting: male, female).

Lifespan/Longevity

Typical lifespan (wild)


Typical lifespan (captivity)


Hystrids are reported to be long-lived. However, not much is known about the lifespan of Atherurus macrourus in the wild. In captivity, Atherurus africanus has been reported to live 23 years, Hystrix brachyura, 21. (Storch and Parker (Editor), 1990)

Behavior

Territory Size
15 km^2 (average)

Atherurus macrourus live in family clans of up to four to eight members, who share common runs, trails, excrement depositories, feeding places, refuges, and territories. Dwellings are, as a rule, not inhabited by one animal, but rather by a group. Typical groups consist of an adult couple and a varying number of young and growing animals. Asiatic brush-tailed porcupines provide extensive care of the young. These animals forage nocturnally and alone, but shelter in groups during the day. Atherurus macrourus individuals are extremely cautious and quiet after they have left their dens, and seem nervous when foraging for food. Porcupines move quickly and can also climb. If these animals are disturbed or pursued, they can run fast enough to get away from humans. Atherurus macrourus settle in any area with sufficient food and natural refuges, or where they can build their own dens. These animals are highly adaptive and can find homes in many different habitats. If food supplies become sparse permanently, these animals leave. (Grzimek, Schlager, and Olendorf, 2003; Storch and Parker (Editor), 1990)

Home Range

Asiatic brush-tailed porcupines in search of food may range widely, travelling distances of up to 15 km (9 miles) per night, depending on the availability of the food in the area. Family clans can have widely overlapping territories, refuges, extrement depositories, feeding places, runs and trails. They can have tunnels about 3.5m (11 feet) long. (Storch and Parker (Editor), 1990)

Key behaviors:
terricolous; fossorial ; nocturnal ; motile ; sedentary ; social .

Communication and Perception

The tendency towards inflation of the facial portion of the skull, and the enlargement of nasal bones is less pronounced in Asiatic brush-tailed porcupines than in other porcupines. The enlarged nasal cavity may allow the animals to have a heightened sense of smell, or it may serve to help retrieving moisture from the air. As in most mammals, chemical cues are widely used in communication. Atherurus macrourus rattle the small cups at the end of their tails, which discourages their predators. (Gould, McKay, and Kirshner (Illustrations), 1998; Storch and Parker (Editor), 1990)

Communicates with:
visual ; acoustic ; chemical .

Other communication keywords:
pheromones ; scent marks ; vibrations .

Perception channels:
visual ; tactile ; acoustic ; vibrations ; chemical .

Food Habits

These animals strictly forage during the night. They are herbivorous and usually feed on vegetation. They enjoy tree bark, roots, tubers, leaves, bulbs, and fallen fruits. However, they sometimes also feed on cultivated crops, insects, and carrion. (Gould, McKay, and Kirshner (Illustrations), 1998; Grzimek, Schlager, and Olendorf, 2003)

Primary Diet:
herbivore (folivore , lignivore).

Animal Foods:
carrion ; insects.

Plant Foods:
leaves; roots and tubers; wood, bark, or stems; seeds, grains, and nuts; fruit; flowers.

Predation

Known predators

Large carnivores such as leopards, humans, large owls, canids, and other cats, hunt porcupines. Atherurus species are protected from most predators by their defensive spines. (Grzimek, Schlager, and Olendorf, 2003; Rabinowitz and Walker, 1991; Storch and Parker (Editor), 1990; WCMC Collaborators, 2005)

Anti-predator adaptations::
aposematic .

Ecosystem Roles

Asiatic brush-tailed porcupines eat fallen seeds and may disperse some seeds. Such pits and holes created by porcupines can be an important small habitat for sensitive plants. Asiatic brush-tailed porcupines also burrow dens in rocks and soil, and tunneling may provide some aeration of the surrounding soil and create habitat for invertebrates and other, small vertebrates. (Murniati et al., 2006; Storch and Parker (Editor), 1990; WCMC Collaborators, 2005)

Key ways these animals impact their ecosystem:
disperses seeds; creates habitat; soil aeration .

Commensal or parasitic species (or larger taxonomic groups) that use this species as a host
  • Plasmodium atheruri

Economic Importance for Humans: Negative

Asiatic brush-tailed porcupines may overfeed on crops, including casava, sweet potatoes, bananas, peanuts, maize, pineapple, mango, and sugarcane. Their habit of eating the a ring of cambium layer around the base of trees results in the death of trees when their vascular tissue is destroyed. Atherurus africanus is known to be a carrier of the malaria parasite, Plasmodium atheruri. (Grzimek, Schlager, and Olendorf, 2003; Storch and Parker (Editor), 1990)

Ways that these animals might be a problem for humans:
injures humans (bites or stings, carries human disease); crop pest.

Economic Importance for Humans: Positive

Asiatic brush-tailed porcupines are hunted for their meat. (Grzimek, Schlager, and Olendorf, 2003)

Ways that people benefit from these animals:
food .
