Muntiacus reevesiReeves's muntjac

Ge­o­graphic Range

Munti­a­cus reevesi has a na­tive range that ex­tends through­out the sub­trop­i­cal forests of south­east­ern China and Tai­wan. It has also be­come es­tab­lished in Eng­land after being in­tro­duced at Woburn, Eng­land (lo­cated in the mid­dle of Bed­ford­shire county) around 1900. Feral pop­u­la­tions may also exist in France, where in­tro­duced in­di­vid­u­als es­caped gar­dens and zoos. (Chap­man, et al., 1994; Helin, et al., 1999; Nowak, ed. and Par­adiso, ed., 1983; South­ern, 1964)

Habi­tat

Munti­a­cus reevesi is a for­est crea­ture in its na­tive coun­try of China. It cre­ates paths through the sub­trop­i­cal rain­forests at mod­er­ate el­e­va­tions, which is why it has been termed by some as a bush hug­ger. It was ob­served that munt­jacs in gen­eral tend to pre­fer habi­tats near streams, but ev­i­dence of this pref­er­ence is not strongly demon­strated in the lit­er­a­ture for this par­tic­u­lar species of munt­jac. Chi­nese munt­jacs will fight to de­fend a fairly spe­cific ter­ri­tory, but males have been shown to tol­er­ate the pres­ence of a sub­or­di­nate male in their ter­ri­tory so long as that male is not in rut.

In Eng­land, M. reevesi ex­hibits slightly dif­fer­ent pref­er­ences for habi­tat. It ap­pears that the feral munt­jacs of Britain are equally happy in habi­tats with and with­out cover; that is, munt­jacs have been found in de­cid­u­ous and conif­er­ous forests as well as agri­cul­tural land, and even sub­ur­ban and urban areas. In some re­spects, it is dif­fi­cult to con­sider habi­tat pref­er­ences when a num­ber of the metapop­u­la­tions within the British pop­u­la­tion were specif­i­cally re­leased into cer­tain en­vi­ron­ments, so their pres­ence in some habi­tats may not ac­tu­ally be an in­di­ca­tion of a pref­er­ence.

Re­li­able in­for­ma­tion on el­e­va­tion pref­er­ences could not be found for the British pop­u­la­tion of M. reevesi, but in its na­tive en­vi­ron­ment, it ap­pears that M. reevesi prefers mod­er­ate el­e­va­tions (mod­er­ate was not de­fined). (Chap­man, et al., 1994; Geist, 1998; Helin, et al., 1999; Nowak, ed. and Par­adiso, ed., 1983)

Phys­i­cal De­scrip­tion

Munti­a­cus reevesi has a chest­nut-col­ored coat with a 4-inch tail that is black above and white below. It has been re­ported that the fe­males tend to be slightly lighter in color than males, but these ob­ser­va­tions were mainly made on cap­tive and feral M. reevesi in Eng­land and have not been cor­rob­o­rated with ob­ser­va­tions of M. reevesi in its na­tive China. Chi­nese munt­jacs stand 43 to 45 cm in height at the shoul­der.

Sex­ual di­mor­phism in M. reevesi leads to larger, heav­ier males that have short antlers (125 to 150 mm) that grow from their pedi­cles and that have long, tusk-like ca­nines (1 to 2 inches long). The ca­nines are not en­tirely fixed to the pre­max­illa so they are less likely to be bro­ken off dur­ing a fight. Both the male and fe­male Chi­nese munt­jacs have bony ridges on their faces that are lined with black hair along the in­side. These ridges ex­tend into hair-cov­ered pedi­cles from which antlers (male) or black tufts of hair (fe­males) pro­ject. Both the male and fe­male Chi­nese munt­jacs also have pre­or­bital glands that pro­duce a creamy liq­uid used for chem­i­cal com­mu­ni­ca­tion.

As with all Munti­a­cus species, M. reevesi has only the upper parts of the 2nd and 5th digit metacarpals pre­sent, a phys­i­ol­ogy known as ple­siometacarpalia. How­ever, un­like other deer species that have 2 hooves of the same size and shape, M. reevesi has one hoof that is smaller than the other and that is lined with hairs that are vis­i­ble in its foot­prints. (Bur­rage, 2000; Grz­imek, 1990; Helin, et al., 1999; Mar­shall, 1967; Nowak, ed. and Par­adiso, ed., 1983; South­ern, 1964)

Re­pro­duc­tion

Males gain ac­cess to fe­males by de­fend­ing ter­ri­tory that over­laps that of fe­males. The males will fight with the tusk-like ca­nines for ac­cess to fe­males in es­trous. The males do not use their antlers in of­fen­sive moves while fight­ing like the white-tailed deer Odocoileus vir­gini­anus, but they spar ex­ten­sively while still young, and use the horns in de­fen­sive moves while fight­ing. (Chap­man, et al., 1997; Geist, 1998; Grz­imek, 1990; Law­son, et al., 2001; Pei, et al., 1995; South­ern, 1964; Yah­ner, 1980)

Munti­a­cus reevesi has year round breed­ing in its nat­ural habi­tat in China. In Eng­land, Chi­nese munt­jacs ap­pear to have a more sea­sonal breed­ing cycle that oc­curs be­tween late Oc­to­ber and early March. Both sexes of M. reevesi de­velop rapidly so that they may reach their re­pro­duc­tive thresh­old weights (12 kg for bucks, 10 kg for does) within a few months of birth (36 weeks for bucks, 24 weeks for does). It is un­likely that very young males will be able to gain ac­cess to a doe in es­trus, but younger males tend to be more re­pro­duc­tively suc­cess­ful than older males due to the qual­ity of their ca­nines.

Un­like other antlered deer, munt­jacs use tusk-like ca­nines to de­fend ter­ri­tory and gain ac­cess to fe­males. When a doe in es­trus is lo­cated, the male will make a buzzing sound and the fe­male will re­spond by lying flat, weav­ing her head and emit­ting a cat-like whine that is a sign of sub­mis­sion. After cop­u­la­tion, male are no longer in­volved with the fe­males and once the rut is over, males lose their antlers. Males may grow antlers in a pe­riod as rapid as 103 days, which is use­ful for a species that can breed year-round. (Chap­man, et al., 1997; Geist, 1998; Grz­imek, 1990; Nowak, ed. and Par­adiso, ed., 1983; South­ern, 1964; Yah­ner, 1980)

Parental in­vest­ment is min­i­mal in M. reevesi. The young de­velop ex­tremely rapidly and are weaned early enough so that by the time that the caloric needs of the young re­ally begin to es­ca­late, they have begun to eat solid foods and are no longer de­pen­dent on their mother’s milk. Lac­ta­tion gen­er­ally oc­curs for only the first 17 weeks. Be­cause the young be­come in­de­pen­dent so early, there is no extra cost to a fe­male to pro­duce males (which would gen­er­ally cost more in nu­tri­tional needs from a mother). By the age of 6 months, adult­hood is reached and the young must leave the mother's ter­ri­tory. (Chap­man, et al., 1997; Grz­imek, 1990)

Lifes­pan/Longevity

Lit­tle is known about the lifes­pan of M. reevesi in the wild. Anec­do­tal ev­i­dence would in­di­cate that Chi­nese munt­jacs, which are de­scribed as a duiker-like (for ex­am­ple, Cepalo­phus niger) or­gan­ism due to its rapid de­vel­op­ment and its gen­er­al­ist ten­den­cies, would prob­a­bly have a sim­i­lar life ex­pectancy: 10 to 12 years. In Eng­land, with a lack of preda­tors and abun­dant food sources, it may be ex­pected that Chi­nese munt­jacs may live even longer.

Be­hav­ior

Munti­a­cus reevesi is a soli­tary, ter­ri­to­r­ial deer that uses its tusk-like ca­nines to de­fend its ter­ri­tory and gain ac­cess to fe­males. It uses its short antlers for par­ry­ing and spar­ring and for de­fen­sive moves while fight­ing. Un­like other antlered deer, the munt­jac uses its horns to shove an op­po­nent off bal­ance and in­flict a tusk blow to the face or head that will hope­fully punc­ture the skin of the face, neck or ears.

Chi­nese munt­jacs cre­ate trails through their ter­ri­tory that they use for ease of move­ment, sim­i­lar to white-tailed deer of North Amer­ica (Odocoileus vir­gini­anus). The fo­liage along these trails often be­comes worn with use. Munt­jacs will also tram­ple down and clear areas for bed­ding down or uri­nat­ing.

Feed­ing bouts in Chi­nese munt­jacs typ­i­cally last 30-40 min­utes; they are most ac­tive at dawn and dusk. As with other ru­mi­nants, munt­jacs will browse for a short time, then chew their cud for some time. Munti­a­cus reevesi is a par­tic­u­larly un­fussy eater and will browse on a wide va­ri­ety of plant and an­i­mal ma­te­ri­als, as well as car­rion and fun­gus. In Britain, M. reevesi has been found to walk up the stems of small saplings in order to reach fo­liage that would oth­er­wise be out of reach. Munti­a­cus reevesi tends to for­age with its head held low, mak­ing soft growl­ing noises as it moves.

As is fur­ther ex­plained in the com­mu­ni­ca­tion sec­tion, Chi­nese munt­jacs use vo­cal­iza­tions and chem­i­cal sig­nals as forms of com­mu­ni­ca­tion. Munti­a­cus reevesi tends to bark when it is feel­ing anx­ious, gen­er­ally due to the pres­ence of a preda­tor or a dom­i­nant con­spe­cific. Chem­i­cal com­mu­ni­ca­tion con­sists pri­mar­ily of scent marks that are placed on veg­e­ta­tion in order to mark ter­ri­tory. The odors pro­duced by the scent glands them­selves may be used for the iden­ti­fi­ca­tion of in­di­vid­u­als, but this has not been ex­ten­sively tested.

Ter­ri­to­ries of M. reevesi fe­males tend to over­lap, but male ter­ri­to­ries tend only to over­lap those of fe­males, not of other males. An ex­cep­tion can be ob­served when males will tol­er­ate the pres­ence of a younger, antler­less male that is not a com­peti­tor for fe­males in es­trus. This serves the sub­servient male well be­cause he does not have to fight other males for his own ter­ri­tory and he can get prac­tice spar­ring with a dom­i­nant male. The dom­i­nant male ben­e­fits be­cause he is gain­ing a co-de­fender of ter­ri­tory with­out giv­ing up any ac­cess to fe­males. (Chap­man, et al., 1993; Chap­man, et al., 1997; Geist, 1998; Un­avail­able, Un­avail­able; Yah­ner, 1980)

Home Range

The home range of the Chi­nese munt­jacs has been stud­ied in feral pop­u­la­tions in Eng­land. In those stud­ies, it was found that range size and usage areas of the range did not dif­fer sea­son­ally or di­ur­nally. These stud­ies also noted that fe­male ter­ri­to­ries tended to over­lap. The min­i­mum range size for adult male M. reevesi in Britain is about 20 hectares. The max­i­mum range size for bucks is ap­prox­i­mately 28 hectares. For M. reevesi in Britain, the min­i­mum range size is 11 hectares, and the max­i­mum range size is 14 hectares. In­for­ma­tion on range sizes for M. reevesi in its na­tive China are not avail­able. It is noted that gath­er­ing data on munt­jacs in their na­tive habi­tats (i.e. dense veg­e­ta­tion), is often dif­fi­cult be­cause they are heard more often than they are seen. (Chap­man, et al., 1993; Mar­shall, 1967)

Com­mu­ni­ca­tion and Per­cep­tion

Munti­a­cus reevesi, as a mem­ber of the Munti­a­cus genus, is often known as a bark­ing deer, yet the func­tion of bark­ing may be over­es­ti­mated by ca­sual ob­servers. While it was orig­i­nally thought that munt­jacs used their barks to com­mu­ni­cate with other munt­jacs to com­mu­ni­cate dan­ger or lo­ca­tion in­for­ma­tion, it ap­pears that the barks of munt­jacs have a more lim­ited func­tion than ex­pected. Barks are pri­mar­ily used in two cir­cum­stances; when preda­tors are sus­pected in the en­vi­ron­ment and dur­ing so­cial en­coun­ters when sub­or­di­nate and dom­i­nant an­i­mals come into con­tact. The hy­poth­e­sis that barks are used as a part of re­pro­duc­tive processes has not been sub­stan­ti­ated. Like­wise, ex­pec­ta­tions that barks were used to com­mu­ni­cate dan­ger to other munt­jacs could not be cor­rob­o­rated in stud­ies. The fre­quency of the barks of munt­jacs pre­vents them from trav­el­ing any sub­stan­tial dis­tance, par­tic­u­larly in dense veg­e­ta­tion, so it is un­likely that barks evolved as a warn­ing re­sponse. It has been hy­poth­e­sized that the bark­ing of munt­jacs is ac­tu­ally a vo­cal­iza­tion of inner anx­i­ety that ac­com­pa­nies being hunted by preda­tors or chal­lenged by a dom­i­nant in­di­vid­ual and that it has lit­tle to do with mat­ing, de­fend­ing ter­ri­tory, food pro­cure­ment or iden­ti­fi­ca­tion of in­di­vid­u­als. Ev­i­dence sup­port­ing this hy­poth­e­sis is found in the ob­ser­va­tions of in­creased bark­ing by the munt­jac at dawn and dusk and in en­vi­ron­ments that have de­creased vis­i­bil­ity, such as very dense grass­land en­vi­ron­ments.

Chi­nese munt­jacs send sig­nals to oth­ers about their iden­tity, their ter­ri­tory and their sex­ual state using a com­bi­na­tion of non-bark vo­cal­iza­tions and chem­i­cals. The non-bark vo­cal­iza­tions that may be emit­ted by Munti­a­cus reevesi are used in re­pro­duc­tive sit­u­a­tions where the male makes a buzzing sound and a fe­male that is will­ing will make a cat-like whine. A main form of com­mu­ni­ca­tion in M. reevesi comes through chem­i­cals emit­ted by the pre­or­bital gland. These chem­i­cals are used as scent mark­ers to de­fine ter­ri­to­ries and to ad­ver­tise pres­ence of an in­di­vid­ual. Stud­ies have shown that the chem­i­cal com­po­si­tion of these se­cre­tions would per­mit munt­jacs to iden­tify an in­di­vid­ual’s age, sex and pop­u­la­tion of ori­gin, but the mere pres­ence of these ca­pa­bil­i­ties within the chem­i­cal does not mean that the munt­jac are using chem­i­cal com­mu­ni­ca­tion in that way. (Board­man and Bourne, 2001; Geist, 1998; Grz­imek, 1990; Nowak, ed. and Par­adiso, ed., 1983; South­ern, 1964; Yah­ner, 1980)

Food Habits

Munti­a­cus reevesi is sur­pris­ingly om­niv­o­rous. It eats bam­boo, seeds, bark, fruit and fo­liage, as most other deer species, but it has also been found to eat eggs and car­rion and is re­ported to be able to hunt small mam­mals and ground-nest­ing birds. It is re­ported to eat hunters' snared pheas­ants in China. In China, M. reevesi tends to be ag­gres­sively de­fen­sive of its ter­ri­tory be­cause while food is avail­able year-round, it is not plen­ti­ful. (Bur­rage, 2000; Grz­imek, 1990; Mar­shall, 1967)

Pre­da­tion

Munti­a­cus reevesi is pre­dated upon by a num­ber of larger mam­mals and rep­tiles in south­east China. These nat­ural en­e­mies in­clude leop­ards, tigers, dholes, jack­als, croc­o­diles and pythons. In the in­tro­duced pop­u­la­tions in Eng­land, the only po­ten­tial preda­tor is the fox. Be­hav­ioral dif­fer­ences may be noted be­tween the Eng­lish pop­u­la­tions and those of China as the lack of preda­tors leads M. reevesi to be much less vig­i­lent in Eng­land and is there­fore con­sid­ered to be com­fort­able with the pres­ence of man and hu­man-al­tered sur­round­ings.

When alarmed, Chi­nese munt­jacs will bark for up to one hour. This dis­tress call, how­ever, does not ap­pear to be meant to warn oth­ers but may sim­ply be a vo­cal­ized ex­pres­sion of in­ter­nal anx­i­ety. This is mainly ev­i­denced by the fact that munt­jac barks tend to be emit­ted within a fre­quency range that would not carry through the dense veg­e­ta­tion that they in­habit. (Bur­rage, 2000; Grz­imek, 1990; Mar­shall, 1967; Yah­ner, 1980)

Ecosys­tem Roles

The alarm barks of Chi­nese munt­jacs are ex­cel­lent warn­ings for other small mam­mals that a preda­tor, such as a tiger or leop­ard, is in the area. In China, the be­hav­ior and dis­tri­b­u­tion of M. reevesi is in­ter­de­pen­dent with the be­hav­ior and dis­tri­b­u­tion of other Cerv­inae species, es­pe­cially M. crinifrons, M. munt­jak and Elapho­dus cephalo­phus. As the most gen­er­al­ized in its food habits of the munt­jacs, M. reevesi has the widest range, pre­fer­ring sub­trop­i­cal for­est areas and tend­ing to occur near water. The other Cerv­inae species have be­come dis­trib­uted in ei­ther higher el­e­va­tions, drier, open en­vi­ron­ments, or wet­ter, denser en­vi­ron­ments. These habi­tat types have led the other Cerv­inae to be­come more spe­cial­ized in their diet and be­hav­ior than M. reevesi.

The im­pacts of munt­jacs and other deer on plant di­ver­sity and wood­land in­ver­te­brates in Eng­land have been stud­ied and it ap­pears that with nat­ural deer pop­u­la­tions, veg­e­ta­tion brows­ing may cre­ate more habi­tats for in­ver­te­brates and the pres­ence of dung may allow for an in­creased di­ver­sity of in­ver­te­brates. This is con­trasted with high-den­sity deer pop­u­la­tions, where deer will over­browse an area and leave min­i­mal plant di­ver­sity and re­duce re­main­ing plant qual­ity for in­ver­te­brates. Sim­i­lar im­pacts have been ob­served on small mam­mal pop­u­la­tions, where munt­jacs may act as di­rect com­peti­tors for re­sources or act as habi­tat mod­i­fiers. Just as with the in­ver­te­brate study, ob­ser­va­tions made about Chi­nese munt­jacs’ im­pact on small mam­mals are den­sity-de­pen­dent. Es­sen­tially, at high den­si­ties, the com­pe­ti­tion for re­sources and habi­tat mod­i­fi­ca­tion through loss of cover will cause a de­cline in the pop­u­la­tions of small mam­mals (such as Apode­mus syl­vati­cus, Mi­cromys min­u­tus, Sorex anareus, Sorex min­u­tus, My­o­des glare­o­lus, Apode­mus flav­i­col­lis, Mus­cardi­nus avel­la­narius) that rip­ples through the food chain, es­pe­cially af­fect­ing the preda­tors of small mam­mals: Mustela ni­valis, Mustela er­minea and Vulpes vulpes. (Bur­rage, 2000; Cooke and Far­rell, 2001; Flow­erdew and Ell­wood, 2001; Stew­art, 2001)

Eco­nomic Im­por­tance for Hu­mans: Pos­i­tive

Munti­a­cus reevesi has pos­i­tive im­pacts for hu­mans in both China and west­ern Eu­ro­pean feral pop­u­la­tions. In both en­vi­ron­ments, M. reevesi is hunted for meat (and in Britain, for sport). They have also been ap­pre­ci­ated in their na­tive en­vi­ron­ments for warn­ing hu­mans in the woods of the pres­ence of a preda­tor an­i­mal, such as a tiger or leop­ard, with their barks.

Eco­nomic Im­por­tance for Hu­mans: Neg­a­tive

Munti­a­cus reevesi does not have any re­ported neg­a­tive im­pacts in its na­tive habi­tat be­cause its pop­u­la­tions are con­trolled by preda­tor species and be­cause it tends to live in for­est en­vi­ron­ments. In Eng­land, how­ever, M. reevesi, unchecked by preda­tors, has be­come the most widely dis­trib­uted deer and has been found to in­habit urban and sub­ur­ban areas, as well as forests. They may be a nui­sance to farm­ers and foresters due to their brows­ing on veg­e­ta­tion, par­tic­u­larly cop­pice.

Con­ser­va­tion Sta­tus

Munti­a­cus reevesi is com­mon in south­east China, there­fore it is not listed as a threat­ened or en­dan­gered species. It ap­pears not to have been stud­ied by many con­ser­va­tion or­ga­ni­za­tions, which most likely in­di­cates that it is not a species of con­cern for those in­volved in pro­tect­ing bio­di­ver­sity.

Other Com­ments

Munti­a­cus reevesi and other mem­bers of the Cerv­inae sub­fam­ily are in­ter­est­ing to ge­neti­cists due to their strange ge­netic his­tory. It ap­pears that while M. reevesi is 2n=46, M. feae is 2n=14 F/13 M, M. crinifrons and M. gong­sha­ne­nis are 2n=8 F/9 M, and M. munt­jak is 2n=6 F/7 M, the small­est known chro­mo­some num­ber for any mam­mal. It is also noted that evo­lu­tion from the more prim­i­tive to more de­rived Munti­a­cus species was rapid, with the fastest evo­lu­tion oc­cur­ring in M. feae, where two dif­fer­ent kary­otypes emerged in only 0.5 Myr. Tax­on­o­mists re­cently added a po­ten­tial new genus Mega­munt­ja­cus to the sub­fam­ily Cerv­inae, al­though it is still being dis­puted whether or not this new species should be its own genus or should fall under the genus Munti­a­cus.

forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.

introduced

referring to animal species that have been transported to and established populations in regions outside of their natural range, usually through human action.

iteroparous

offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).

keystone species

a species whose presence or absence strongly affects populations of other species in that area such that the extirpation of the keystone species in an area will result in the ultimate extirpation of many more species in that area (Example: sea otter).

motile

having the capacity to move from one place to another.

native range

the area in which the animal is naturally found, the region in which it is endemic.

omnivore

solitary

lives alone

suburban

living in residential areas on the outskirts of large cities or towns.

tactile

uses touch to communicate

temperate

that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle).

territorial

defends an area within the home range, occupied by a single animals or group of animals of the same species and held through overt defense, display, or advertisement

tropical

the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south.

urban

living in cities and large towns, landscapes dominated by human structures and activity.

viviparous
