|Jackson's mongoose range|
Jackson's mongoose (Bdeogale jacksoni) is a species of mongoose belonging to the genus Bdeogale . Discovered in 1889 by Frederick John Jackson, Oldfield Thomas in 1894 described it as Galeriscus jacksoni. It is most closely related to the black-footed mongoose of the same subgenus Galeriscus and both are sometimes united in a single species.
With a head and body length of more than 50 cm (20 in) and a body weight of 2–3 kg (4.4–6.6 lb), it is a large mongoose. Its long and dense fur is grizzled black and white, the cheeks, the throat and the sides of the neck are very yellowish, the legs are dark brown or black, and the bushy tail is white.
Jackson's mongoose feeds on rodents and insects, especially on army ants, and is mainly nocturnal and crepuscular and possibly solitary. Its distributional range in Kenya, Uganda and Tanzania is limited to some arboreous mountain regions. It appears to be rare, and in 2008, the IUCN classified it as Near Threatened.
Galeriscus jacksoni was the scientific name proposed by Oldfield Thomas in 1894 based on a skin of a badger-like animal collected by Frederick John Jackson in Kenya. He specified the type locality as Mianzini in Maasailand at an elevation of 2,400 m (8,000 ft). The generic name Galeriscus was recognised as a valid taxon by Paul Matschie, Glover Morrill Allen and Donovan Reginald Rosevear.
Jackson's mongoose was placed in the genus Bdeogale by Reginald Innes Pocock in 1916, who recognised that the animal was a mongoose and considered Galeriscus a synonym of Bdeogale.This classification has been widely followed.
Jackson's mongoose is a large mongoose with a bushy tail. Its head and body length is 50.8–57.1 cm (20.0–22.5 in), its tail length is 28.3 to 32.4 centimeters, its hind foot length is 8.6 to 10.8 cm, its ear length is 2.3 to 3.5 cm and its body weight is 2–3 kg. Young but already breeding animals may be markedly smaller than adults. From the black-footed mongoose, it is distinguishable by its much longer fur, especially on the tail, and yellowish tints on the neck and the throat.
The long and dense dorsal fur is grizzled black and white. The dorsal hairs are 20 mm (0.79 in) long with black and white rings. The muzzle and the chin are brownish white and the cheeks, the throat and the sides of the neck are very yellowish. The legs are dark brown or black and the tail is white. The ventral side is light gray and the underfur is dense and woolly. The pinnae are round and broad and the muzzle is blunt. The rhinarium is large, and the hairless extension of the median groove divides the upper lip. The fore and hind feet have only four digits. A hallux and pollex are absent as is common with Bdeogale. The soles are naked, and the claws are thick and strong.
The dentition of Jackson's mongoose is typical for mongooses. Three incisors, one canine, four premolars and two molars are on either side of each jaw. The total number of teeth is 40 and the dental formula is 184.108.40.206 × 2 = 40.
Jackson's mongoose is distributed in central and southern Kenya and southeastern Uganda, where it was recorded in the Aberdare Range, Mount Kenya and the Mount Elgon mountains at elevations from 300 to 3,300 m (980 to 10,830 ft). It inhabits lowland forests, bamboo and montane forests. In Tanzania's Udzungwa Mountains, it was first recorded in 2002 in the Matundu Forest.
Jackson's mongoose is mainly nocturnal and crepuscular.In the Udzungwa Mountains, most of the 25 camera trap photos were taken by night. It is possibly solitary, but was also recorded in pairs and occasionally in groups of four. Nothing is known about its reproduction.
It probably hunts frequently in the thick herbaceous plant growth around swamps.It is an omnivore. Analysis of 40 feces samples collected in the Aberdare Mountains revealed that they contained army ants, beetles, weevils, millipedes and caterpillars, rodents including Otomys , Dasymys and Praomys , as well as snails, lizards, and of snake eggs. The diet of juveniles consisted foremost of rodents and insects. Feeding on army ants may be a recent evolutionary adaptation to this diet.
Jackson's mongoose occurs in isolated populations and appears to be rare.It has been listed as Near Threatened on the IUCN Red List since 2008, assuming a declining population size within the last 10 years due to habitat destruction. Given its dependence on forest habitat, its main threat is likely to be ongoing forest loss. It has been recorded in protected areas such Aberdare National Park, Mount Kenya National Park and Udzungwa Mountains National Park. It is suspected to also live in Mount Elgon National Park and probably more widely distributed than currently known. Full protection of forests adjacent to the Udzungwa Mountains National Park and a survey in other groundwater-dependent forests in the region has been recommended.
The honey badger, also known as the ratel, is a mammal widely distributed in Africa, Southwest Asia, and the Indian subcontinent. Because of its wide range and occurrence in a variety of habitats, it is listed as Least Concern on the IUCN Red List.
A genet is a member of the genus Genetta, which consists of 14 to 17 species of small African carnivorans. Genet fossils from the Upper Miocene and forward have been found at sites in Ethiopia, Kenya and Morocco. The common genet is the only genet present in Europe and occurs in the Iberian Peninsula and France.
The servaline genet is a genet species native to Central Africa. As it is widely distributed and considered common, it is listed as Least Concern on the IUCN Red List.
Bdeogale is a mongoose genus that was proposed by Wilhelm Peters in 1850 based on a mongoose specimen collected in Mozambique. This genus contains three species native to the rainforests of central and western Africa. They are primarily terrestrial and insectivorous.
The black-footed mongoose is a mongoose species native to Central Africa, where it inhabits deep deciduous forests from eastern Nigeria to the southern Democratic Republic of the Congo. It has been listed as Least Concern on the IUCN Red List since 2008. It is omnivorous and feeds on ants, termites, Orthoptera, small rodents, frogs, lizards and fruits. It is mostly solitary and nocturnal.
The white-tailed mongoose is on average the largest species in the mongoose family (Herpestidae). It is the only member of the genus Ichneumia.
The Liberian mongoose is a small carnivoran belonging to the mongoose family (Herpestidae). It is the only member of the genus Liberiictis. Phylogenetic analysis shows it is closely related to other small, social mongooses and that the banded mongoose is its closest relative.
Meller's mongoose is a species of mongoose found in Africa. It occurs in Democratic Republic of the Congo, Malawi, Mozambique, South Africa, Swaziland, Tanzania, Zambia and Zimbabwe. It is the only member of the genus Rhynchogale.
The Angola colobus, Angolan black-and-white colobus or Angolan colobus, is a primate species of Old World monkey belonging to the genus Colobus.
The black and rufous elephant shrew, the black and rufous sengi, or the Zanj elephant shrew is one of the 17 species of elephant shrew found only in Africa. Like other members of the genus Rhynchocyon, it is a relatively large species, with adults averaging about 28 cm (11 in) in length and 450-700 g (1.0-1.5 lb) in weight. It is native to the lowland montane and dense forests of Kenya and Tanzania. It eats insects such as beetles, termites, and centipedes, using its proboscis to dig them from the soil and its tongue to lick them up. It typically builds ground level nests for shelter requiring dry leaf litter often at the base of trees. Like most elephant shrews, it lives in monogamous pairs, defending hectare-sized territories.
Rhynchocyon is a genus of elephant shrew in the family Macroscelididae. Members of this genus are known colloquially as the checkered elephant shrews or giant sengis. It contains the following four species:
The Uzungwa red colobus, also known as the Udzungwa red colobus or Iringa red colobus, is a species of primate in the family Cercopithecidae. It is endemic to riverine and montane forest in the Udzungwa Mountains in Tanzania. It is threatened by habitat loss.
Kihaule's mouse shrew is a species of mammal in the family Soricidae endemic to Tanzania where it is known only from the Udzungwa Mountains, at the western end of the Eastern Arc Mountains. Its natural habitats are subtropical or tropical moist montane forests and plantations. It is threatened by habitat destruction and the International Union for Conservation of Nature has assessed its conservation status as being "endangered". It was named after Philip M. Kihaule, a medical-entomological technician, who considerably contributed to the documenting of the small mammals of Tanzania and collected the type specimen of this shrew.
The grey-faced sengi is a species of elephant shrew that is endemic to the Udzungwa Mountains of south-central Tanzania. The discovery of the species was announced in January 2008; only 15 species of elephant shrew were known until then, and the last discovery was made more than 120 years ago. As the name implies, the species is characterised by a distinctive grey face and a black rump, as well as being larger than the other species of elephant shrews.
The Sanje mangabey is a highly endangered Old World monkey of the white-eyelid mangabey group from the Eastern Arc Mountains in Tanzania. They are about 50–65 centimetres (20–26 in) in length, excluding the tail, and their body colour is greyish. Fruit makes up about 70% of their diet. They live in valley forests and on mountain slopes, but are mostly ground-dwelling, which makes them susceptible to hunting and poaching. Their habitat is being degraded, and the International Union for Conservation of Nature has assessed their conservation status as being "endangered".
Helogale is a genus of the mongoose family (Herpestidae). It consists of two species and 12 subspecies:
