Golden-rumped Elephant Shrew
The golden-rumped elephant shrew (''Rhynchocyon chrysopygus'') is a small African mammal. It is the largest species of the elephant shrew family along with its close relative the grey-faced sengi. It is classified as endangered. Taxonomy and description The golden-rumped elephant shrew is found in the northern coastal areas in and around Arabuko Sokoke National Park Mombasa in Kenya. Its name derives from the conspicuous golden fur on its hindquarters, distinctive golden coloration on its rump, and grizzled gold forehead contrasting with its dark reddish-brown color. The golden-rumped elephant shrew has long muscular rear legs and shorter, less developed forelegs. Like other elephant shrews, this species has a long and flexible snout, which is where its genus gets its name. Its tail is largely black except for the last third, which is white with a black tip. On juveniles, the fur shows vestigial traces of a checkerboard pattern seen on giant elephant shrews like the checkered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Fauna Of Kenya
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 Kenya
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, pinniped, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wit ...

EDGE Species
Evolutionarily Distinct and Globally Endangered (EDGE) species are animal species which have a high 'EDGE score', a metric combining endangered conservation status with the genetic distinctiveness of the particular taxon. Distinctive species have few closely related species, and EDGE species are often the only surviving member of their genus or even higher taxonomic rank. The extinction of such species would therefore represent a disproportionate loss of unique evolutionary history and biodiversity. Some EDGE species, such as elephants and pandas, are well-known and already receive considerable conservation attention, but many others, such as the vaquita (the world's rarest cetacean) the bumblebee bat (arguably the world's smallest mammal) and the egg-laying long-beaked echidnas, are highly threatened yet remain poorly understood, and are frequently overlooked by existing conservation frameworks. The Zoological Society of London launched the EDGE of Existence Programme in 2007 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephant Shrews
Elephant shrews, also called jumping shrews or sengis, are small insectivorous mammals native to Africa, belonging to the family Macroscelididae, in the order Macroscelidea. Their traditional common English name "elephant shrew" comes from a perceived resemblance between their long noses and the trunk of an elephant, and their superficial similarity with shrews (family Soricidae) in the order Eulipotyphla. However, phylogenetic analysis has revealed that elephant shrews are not properly classified with true shrews, but are in fact more closely related to elephants than to shrews. In 1997, the biologist Jonathan Kingdon proposed that they instead be called "sengis" (singular ''sengi''), a term derived from the Bantu languages of Africa, and in 1998, they were classified into the new clade Afrotheria. They are widely distributed across the southern part of Africa, and although common nowhere, can be found in almost any type of habitat, from the Namib Desert to boulder-strewn ou ...

Human Impact On The Environment
Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it w ...

Nest
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and several social insec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escape Distance
The flight zone of an animal is the area surrounding an animal that if encroached upon by a potential predator or threat, including humans, will cause alarm and escape behavior. The flight zone is determined by the animal's flight distance, sometimes called flight initiation distance (FID) which extends horizontally from the animal and sometimes vertically. It may also be termed escape distance, alert distance, flush distance, and escape flight distance. Swiss zoologist Heini Hediger distinguished between ''flight distance'' (run boundary), ''critical distance'' (attack boundary), '' personal distance'' (distance separating members of non-contact species, as a pair of swans), and ''social distance'' (intraspecies communication distance). Flight distance can be used as a measure of the willingness of an animal to take risks. Escape theory predicts that the probability of fleeing and flight distance increase as predation risk increases and decrease as escape cost increases. Flight ...

Southern Banded Snake-eagle
The southern banded snake eagle, also known as the East African snake eagle or fasciated snake eagle (''Circaetus fasciolatus'') is a species of snake eagle in the family Accipitridae which is found in eastern Sub-Saharan Africa. Description The Southern banded snake eagle is a rather small, stocky snake eagle with a large, rounded head which has a hooded beak. It has a grey-brown head contrasting slightly with the mainly blackish-brown upperparts and whitish underparts. The tail has a white tip and shows three distinct dark bands on the underside. The large eyes are pale yellow eyes, the feet and cere are yellow and the bill us black. The juvenile lacks the grey head, has mainly dark upperparts and the whitish pale underparts are marked with dark streaks on the face, throat and upper breast. The total length varies from 55 to 60 cm with females larger than males. Voice The Southern banded snake eagle is unobtrusive and is normally found due to its noisy, high-pitched call, ...
