Forest shrew range |
The forest shrew (Myosorex varius) is a species of shrew in the mouse shrew family, Soricidae. [2] It is found in Lesotho, South Africa, and Eswatini. [1] Its natural habitats include temperate forests, dry savanna, Mediterranean-type shrubby vegetation, and temperate grassland. [1] The term "forest shrews" in the plural is sometimes confusingly used to collectively refer to a different genus, Sylvisorex .
The forest shrew grows to a length around 12.5 cm (5 in) with a tail of 4.3 cm (1.7 in) and an average mass of about 12 g (0.4 oz). In KwaZulu-Natal and the Drakensberg region, the males are larger than the females, but in the Cape Colony, the sexes are of similar sizes. This shrew is covered in short, dense fur, dark grey or brown above and paler underneath. [3]
The forest shrew is native to South Africa, Lesotho, and Eswatini. In upland areas, it is often the commonest small mammal, but it is less common in coastal areas. It is found in a wide range of primary and secondary habitats, including forests, grassland, scrub, semidesert, karoo, and fynbos. [1]
The forest shrew excavates a shallow burrow or takes over the burrow of another small mammal. The complex of passages has several entrances and a nesting chamber containing dry grasses. These shrews are territorial and a breeding pair of shrews is often found in a nest. [3]
The forest shrew is mainly nocturnal and is an insectivore, but its diet also includes any small invertebrates it can find, including earthworms, millipedes, centipedes, crustaceans, and spiders. The forest shrew is preyed upon by barn owls, marsh mongooses, striped weasels, and striped polecats. To avoid predation, it spends most of its time in its burrow and only leaves when it needs to feed or defecate. Its droppings are very pungent. [3]
The breeding season varies across the forest shrew's range. In some areas, breeding takes place all year round, but in others, it is correlated with the higher rainfall which occurs in the summer, while unusually wet weather at other times of year can spark further reproductive activity. [4]
The forest shrew often contains the brachylaimid trematode Renylaima capensis in its kidney and ureter. This parasitic fluke has been found to have a three-host lifecycle, the first intermediate host being the terrestrial slug Ariostralis nebulosa and the second, another slug Ariopelta capensis . The forest shrew feeds on both these slugs. [5]
Feeding as it does on small invertebrates, the forest shrew tends to accumulate any environmental contaminants in its tissues. Earthworms are known to bioaccumulate lead and the levels of lead in forest shrews are found to rise when they eat contaminated earthworms. This enables the shrews to be used as bioindicators of heavy metal pollution. [6]
The IUCN lists the forest shrew as being of "Least Concern" because it has a wide distribution and is common over much of its range and the population seems stable. It is able to adapt to variations in its habitat and no specific threats have been identified. [1]
The North American least shrew is one of the smallest mammals, growing to be only up to 3 inches long. It has a long pointed snout and a tail never more than twice the length of its hind foot. The dense fur coat is either grayish-brown or reddish-brown with a white belly. Its fur becomes lighter in the summer and darker in the winter. Although similar in appearance to several species of rodents, all shrews are members of the order Eulipotyphla and should not be mistaken for a member of the order Rodentia. The North American least shrew's eyes are small and its ears are completely concealed within its short fur, giving it very poor eyesight and hearing.
The southern bald ibis is a large bird found in open grassland or semi-desert in the mountains of southern Africa. Taxonomically, it is most closely related to its counterpart in the northern regions of Africa, the waldrapp. As a species, it has a very restricted homerange, limited to the southern tips of South Africa in highland and mountainous regions.
The wildlife of Cameroon is composed of its flora and fauna. Bordering Nigeria, it is considered one of the wettest parts of Africa and records Africa's second highest concentration of biodiversity. To preserve its wildlife, Cameroon has more than 20 protected reserves comprising national parks, zoos, forest reserves and sanctuaries. The protected areas were first created in the northern region under the colonial administration in 1932; the first two reserves established were Mozogo Gokoro Reserve and the Bénoué Reserve, which was followed by the Waza Reserve on 24 March 1934. The coverage of reserves was initially about 4 percent of the country's area, rising to 12 percent; the administration proposes to cover 30 percent of the land area.
The wildlife of South Africa consists of the flora and fauna of this country in Southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants.
Geoxus valdivianus, also known as the long-clawed mole mouse or Valdivian long-clawed akodont, is a species of rodent in the tribe Abrotrichini of family Cricetidae found in the Valdivian temperate rain forests and Magellanic subpolar forests of Argentina and Chile. It is one of two species in the genus Geoxus.
The highveld gerbil is a species of rodent found in Angola, Botswana, Lesotho, Namibia, South Africa, Eswatini, Zambia, and Zimbabwe. Its natural habitats are dry savanna, temperate shrubland, subtropical or tropical dry shrubland, temperate grassland, and temperate desert. This is a common species with a wide range and the International Union for Conservation of Nature has rated it as being of "least concern" as of 2008.
Amblysomus is a genus of the golden mole family, Chrysochloridae, comprising five species of the small, insect-eating, burrowing mammals endemic to Southern Africa. All five species can be found in South Africa and some are also found in Eswatini and Lesotho.
Marley's golden mole is a species of burrowing mammal in the golden mole family, Chrysochloridae. It is found in South Africa and possibly Eswatini. It has been separated from Amblysomus hottentotus by Bronner. Its natural habitat is indigenous forests and moist grassland, and also gardens. It is classified as Endangered in the IUCN Red List of Threatened Species. The main threats it faces are habitat degradation, either through overgrazing by cattle or the removal of vegetation for firewood, and urbanization.
Sclater's golden mole is a species of mammal in the family Chrysochloridae. It is found in Lesotho and South Africa. Its natural habitats are subtropical or tropical dry and high-altitude shrubland, Mediterranean-type shrubby vegetation, temperate grassland, arable land, pastureland, rural gardens, and urban areas. This species is locally common, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The rough-haired golden mole is a species of mammal that live mostly below ground. They have shiny coats of dense fur and a streamlined, formless appearance. They have no visible eyes or ears; in fact, they are blind - the small eyes are covered with hairy skin. The ears are small and are hidden in the animal's fur.
The reddish-gray musk shrew is a species of mammal in the family Soricidae. It is found in Angola, Botswana, Democratic Republic of the Congo, Eswatini, Lesotho, Malawi, Mozambique, Namibia, Nigeria, South Africa, Tanzania, Zambia, and Zimbabwe. Its natural habitats are lowland forests, subtropical or tropical high-elevation grassland, and caves.
The greater red musk shrew is a species of mammal in the family Soricidae. It is found in Lesotho, Mozambique, South Africa, and Eswatini. Its natural habitats are moist savanna, temperate grassland, and rural gardens. Like most shrew species, C. flavenscens is nocturnal. The greater red musk shrew is considered to be asocial and territorial, with males using scent marking to establish their territory. Males appear to be more aggressive than females, and their aggression increases with greater population density.
Myosorex is a mammal genus in the Soricidae (shrew) family. The genus, collectively referred to as the mouse shrews, contains these species:
The dark-footed mouse shrew is a species of mammal in the family Soricidae found in Mozambique, South Africa, Eswatini, and Zimbabwe. Its natural habitat is subtropical or tropical moist montane forests. It was formerly sometimes called the dark-footed forest shrew.
