Cape spiny mouse
  Extant (resident)

The Cape spiny mouse (Acomys subspinosus) is a murid rodent found in the Western Cape province of South Africa. They have a dorsal covering of spiny hairs with dark grey-brown colouration, and a white underbelly. The Cape spiny mouse has large eyes and ears and a scaly, nearly bald tail that is brittle and can break off readily either as a whole or in part if it is caught. Their total length is 17 cm (6.7 in), with an 8 cm (3.1 in) tail, and they typically weigh 22 g (0.78 oz).

Range

This species is largely endemic to the Western Cape province of South Africa; its range just extends into the Eastern and Northern Cape provinces. The extent of occurrence is greater than 20,000 km², and can occur up to about 1,000m above sea level.

Habitat

Its natural habitats are Mediterranean-type shrubby vegetation and rocky areas. They are terrestrial and nocturnal, but can be active in early morning and late afternoon in shadows cast by rocks.

Behaviour

Cape spiny mice may live singly or in small groups. They feed almost exclusively on seeds, especially ant dispersed seeds of Restionaceae and Proteaceae with elaiosomes. The remainder of the diet consists of green plant material and insects, millipedes, and snails. In addition, the cape spiny mouse feed extensively on Protea humiflora flower.

Breeding

Rather than having one set breeding season, cape spiny mice are opportunistic breeders, only reproducing when they have sufficient food sources. [2] They produce litters of 2-5 pups.

Value

The cape spiny mouse contributes significantly to the pollination of Protea humiflora , and in turn gains the food resources that enable winter breeding. In addition to being a potential pollinator for a number of plant species, it also has a role in seed predation and hoarding in the fynbos, potentially contributing to the evolution of myrmecochory as a mechanism to evade rodent seed predation.

<span class="mw-page-title-main">Deomyinae</span> Subfamily of rodents

The subfamily Deomyinae consists of four genera of mouse-like rodents that were previously placed in the subfamilies Murinae and Dendromurinae. They are sometimes called the Acomyinae, particularly in references that antedate the discovery that the link rat, Deomys ferugineus, is part of the clade. Deomyinae is the older name and therefore has priority over Acomyinae.

<span class="mw-page-title-main">Spiny mouse</span> Genus of rodents

The term spiny mouse refers to any species of rodent within the genus Acomys. Similar in appearance to mice of the genus Mus, spiny mice are small mammals with bare tails which contain osteoderms, a rare feature in mammals. Their coats are endowed with unusually stiff guard hairs similar to the spines of a hedgehog; this trait is the source of the common name, spiny mouse.

<span class="mw-page-title-main">Golden spiny mouse</span> Species of rodent

The golden spiny mouse gets its name from the reddish-orange spiny fur that covers its body from head to tail. This coarse, inflexible fur is thought to protect it from predation. Aside from the golden fur that covers its head and upper parts, its flanks are yellow and its underside is pale. It has gray legs with pale feet and black soles. It is also described as having a small, but distinct white spot under each eye. It is often found in the wild missing a part or all of its tail because it is able to shed this as a defense mechanism. However, it is not known how this is done, how often it can occur, or under what conditions. It lives an average of three years in the wild. It is omnivorous and feeds on seeds, desert plants, snails, and insects. Living in desert regions, it is a xeric animal that obtains water from the plants that it eats and produces very concentrated urine in order to conserve water. A. russatus is naturally nocturnal, but adapts to being diurnal when it shares a habitat with A. cahirinus.

<span class="mw-page-title-main">Cape elephant shrew</span> Species of mammal

The Cape elephant shrew, also known as the Cape rock elephant-shrew, or Cape rock sengi, is a species of elephant shrew in the family Macroscelididae. It is endemic to South Africa, although it is a relatively common animal. Its natural habitat is rocky areas. Elephant shrews are not closely related to other species of shrews and to rodents such as mice. E. edwardii has been observed to be a non-flying mammal pollinator of the pagoda lily. Elephant shrews are floral pollinators due to their largely insectivorous diet. Elephant-shrews are pollinators of Hyobanche atropurpurea. It uses its long slender tongue to feed on the pagoda lily's nectar while getting the lily's pollen on its long nose. E. edwardii is also a pollinator of Protea sulphurea.

The eastern spiny mouse or Arabian spiny mouse is a species of rodent in the family Muridae. They have a wide range, having been found in Middle Eastern deserts, as well as being prevalent in riverine forests in Africa. This is the only species of spiny mouse which may have black coloration. Their diet is similar to other species of spiny mouse, consisting mostly of seeds.

Flexible or opportunistic breeders mate whenever the conditions of their environment become favorable. Their ability and motivation to mate are primarily independent of day-length (photoperiod) and instead rely on cues from short-term changes in local conditions like rainfall, food abundance and temperature. Another factor is the presence of suitable breeding sites, which may only form with heavy rain or other environmental changes.
