Cape Spiny Mouse
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 coloration, 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 , with an tail, and they typically weigh . 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. Behavior Cape spiny mice may live singly or in small groups. They feed almost e ...

Opportunistic Breeder
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.WE Duellman, L Trueb. ''Biology of amphibians.'' The Johns Hopkins University Press, 1994, p. 20 Thus, they are distinct from seasonal breeders that rely on changes in day length to induce entry into estrus and to cue mating, and continuous breeders like humans that can mate year-round. Other categories of breeders that perhaps can be subdivided under the heading "opportunistic" have been used to describe many species, such as many that are anurans like frogs. These include sporadic wet and sporadic dry, describing animals that breed sporadically not alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protea Humiflora
''Protea humiflora'', the patentleaf sugarbush, is a flower-bearing shrub belonging to the ''Protea'' genus. The plant is endemic to South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countri ... and occurs from the Du Toitskloof Mountains to the Langeberg and Waboomsberg. The plant grows to 2 m in diameter and flowers from July to September with its peak in August. Fire destroys the plant but the seeds survive. The seeds are stored in a shell and spread by the wind. The plant is unisexual. Pollination takes place through the action of rats and mice. The plant grows on dry slopes of Karoo fynbos at altitudes of 450 - 1 200 m.

Endemic Fauna Of South Africa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of South Africa
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. Geography South Africa is located in subtropical southern Africa, lying between 22°S and 35°S. It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than . The interior of the country consists of a large, nearly flat, plateau with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1838
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...
