Family: Cervidae
Subfamily: Cervinae
Genus: Muntiacus
Species: Muntiacus gongshanensis

Geographic Range

Muntiacus gongshanensis can be found in Southern China, Tibet, Myanmar, and Northern Thailand. (Macdonald and Norris, 2001)

Biogeographic Regions:
palearctic (native ); oriental (native ).

Habitat

Muntiacus gongshanensis prefers habitats with productive evergreen, lowland forests. (Macdonald and Norris, 2001; Worlddeer, 2005)

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

Terrestrial Biomes:
forest .

Physical Description

Mass
18 to 24 kg; avg. 21 kg
(39.6 to 52.8 lbs; avg. 46.2 lbs)


Muntiacus gongshanensis has a dark, chestnut brown coat and may be conspecific with Muntiacus crinifrons, which resembles M. gongshanensis in appearance. Muntiacus gongshanensis has small, dagger like antlers, which are hidden in a tuft of reddish colored hair. Females can reach 57 to 61 centimeters in height, where males only reach 47 to 52 centimeters in height, both sexes weigh between 18 and 20 kilograms (Macdonald and Norris, 2001). However, a weight of 24 kilograms was reported for a male in one study (Schaller and Vrba, 1996). (Macdonald and Norris, 2001; Schaller and Vrba, 1996)

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

Reproduction

Breeding interval
Gongshan muntjac interbirth intervals are not known.

Breeding season
Gongshan muntjacs may breed throughout the year.

Number of offspring
1 to 2; avg. 1

Gestation period
0.01 months (high)

Time to weaning
2 months (average)

Time to independence
6 months (average)

Age at sexual or reproductive maturity (female)
6 months (low)

Age at sexual or reproductive maturity (male)
9 months (low)

Reproduction behavior of M. gongshanensis is not documented, however, in Muntiacus reevesi, males demarcate and aggressively defend small territories against other males. These territories may overlap with several female territories. (Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006)

Mating systems:
polygynous .

Little is known about mating systems in M. gongshanensis. In their close relative, Muntiacus crinifrons, breeding occurs continuously throughout the year. They have no distinct breeding season and females may go into estrous before reaching full body size. In one study, it was found that some lactating females were carrying fetuses, indicating that post-partum estrous occurs in this species. Although the gestation period is not known for M. gongshanensis, in Muntiacus reevesi gestation lasts between 209 to 220 days. Typically a single young is born, twins are rare. (Geist, 1998; Nowak, 1999; Wood and Myers, 2006)

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

Nothing is known about parental care in M. gongshanensis. In other species of Muntiacus, however, maturation progresses quickly and females can carry one developing young in the uterus while nursing another. Both sexes develop rapidly, becoming independent within 6 months after birth. (Dueling and Myers, 2004; Geist, 1998; Wood and Myers, 2006; Worlddeer, 2005)

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

Lifespan/Longevity

Extreme lifespan (wild)
11 years (high)

The lifespan of M. gongshanensis is unknown. However, a wild, pregnant female M. crinifrons was captured at 11 years of age. (Lu and Sheng, 1984; Wood and Myers, 2006)

Behavior

No studies have been done on the behavior of M. gongshanensis. However, it is probably similar to that of the close relative, M. crinifrons. Muntiacus crinifrons is solitary and very territorial. When a male enters another male’s territory, the resident male attacks the other male, using their large, tusk-like, upper canines. Muntiacus crinifrons defend their territories from conspecifics as well as other deer species. Muntjac species are generally active at dusk and dawn. (Geist, 1998; Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006)

Home Range

Nothing is known about the home range of M. gongshanensis, but M. reevesi that were released in England had home ranges of approximately 20 ha and females had home ranges of approximately 12 ha. (Nowak, 1999; Wood and Myers, 2006)

Key behaviors:
terricolous; crepuscular ; motile ; sedentary ; solitary ; territorial .

Communication and Perception

No studies have been done on this topic for M. gongshanensis. However, M. crinifrons individuals use secretions from frontal and preorbital glands to mark territorial boundaries. They also use scents to indicate reproductive status. Muntiacus crinifrons uses visual signals. For instance, the white fur on the underside of the tail can be used to show a predator or an opponent that they have been detected. A raised frontal tuft can have the same meaning. Auditory signals may also be used, such as a barking sound used when a predator has been detected. Male M. reevesi use low postures and buzzing noises during courtship. (Dueling and Myers, 2004; Geist, 1998; Nowak, 1999; Wood and Myers, 2006)

Communicates with:
visual ; acoustic ; chemical .

Perception channels:
visual ; tactile ; acoustic ; chemical .

Food Habits

Not much has been reported on the food habits of M. gongshanensis. Most muntjac species are described as omnivorous, however, the closely related species, M. crinifrons, seems to be mainly herbivorous. A study of stomach contents showed that the diet is made up of fruits, twigs, and leaves. (Lu and Sheng, 1984; Wood and Myers, 2006)

Primary Diet:
herbivore (folivore , frugivore ).

Plant Foods:
leaves; wood, bark, or stems; fruit.

Predation

Known predators

Little is known about predation on Gongshan muntjacs, but humans are suspected of being important predators. In M. crinifrons dholes and leopards are important predators. Some species of Muntiacus flee from predators on well maintained trails and hide in dense undergrowth. (Dueling and Myers, 2004; Geist, 1998; Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006; Worlddeer, 2005)

Ecosystem Roles

Gongshan muntjacs are likely to be important in tree seed dispersal in their native ecosystems. They are also important prey for large predators, such as leopards. (Geist, 1998; Lu and Sheng, 1984; Wood and Myers, 2006)

Key ways these animals impact their ecosystem:
disperses seeds.

Economic Importance for Humans: Negative

Economic Importance for Humans: Positive

Gongshan muntjacs are hunted by native populations for their meat, horns, and hides. They are also important members of healthy, native ecosystems. (Lu and Sheng, 1984; Rabinowitz and Khaing, 1998; Rabinowitz, Amato, and Saw Tun Khaing, 1998; Sheng and Lu, 1980; Wood and Myers, 2006; Worlddeer, 2005)

Ways that people benefit from these animals:
food ; body parts are source of valuable material.

Conservation Status

IUCN Red List: [link]:
Data Deficient.

US Federal List: [link]:
No special status.

CITES: [link]:
No special status.

Muntiacus gongshanensis numbers appear to be decreasing because of over hunting by local human populations. Gongshan muntjacs are considered data deficient, more research is needed to determine their conservation status. (Deer Specialist Group, 2006; Worlddeer, 2005)

Other Comments

There is controversy regarding the taxonomic status of Gongshan muntjacs. “ Muntiacus gongshanensis has always been problematic since it was described on the basis of a single, odd karyotype" (C. P. Groves, pers. comm.). Amato, Eagan, and Rabinowitz (1999) suggest that M. crinifrons and M. gongshanensis should be treated as a single taxon because morphological and molecular data from multiple specimens does not diagnose M. gongshanensis as distinct. They suggest that further study must be done. (Amato, Eagan, and Rabinowitz, 1999)
