Egyptian Pygmy Shrew
The Egyptian pygmy shrew or sacred shrew (''Crocidura religiosa'') is a species of mammal in the family Soricidae. It is endemic to Egypt. Its natural habitat is arable land. It is threatened by habitat loss, partially caused by the construction of the Aswan Dam. They are in length and weigh , making them one of the smallest shrews in Egypt. Breeding Like most shrews, it is a nocturnal animal, hiding during day in burrows and crevices. Its diet is mostly insectivorous. It is solitary and territorial. Female pygmy shrews give birth to litters of one to ten, hairless young with closed eyes. Their eyes open at 13 days and they are weaned at 20 days. The young reach sexual maturity at two to three months and live for 12 to 18 months. Description The Egyptian pygmy shrew has grey fur, tinged with brown on the upperparts and tipped with white on the paler underparts. The bristly tail is grey on top and white underneath and the feet are pale and almost hairless. It has small eyes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
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 with Saur ...

Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Aswan Dam
The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt. Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin. These flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pepi II
Pepi II Neferkare (2284 BC – after 2247 BC, probably either 2216 or 2184 BC) was a pharaoh of the Sixth Dynasty in Egypt's Old Kingdom who reigned from 2278 BC. His second name, Neferkare (''Nefer-ka-Re''), means "Beautiful is the Ka of Re". He succeeded to the throne at age six, after the death of Merenre I. Pepi II's reign marked a sharp decline of the Old Kingdom. As the power of the nomarchs grew, the power of the pharaoh declined. With no dominant central power, local nobles began raiding each other's territories and the Old Kingdom came to an end within a couple of years after the close of Pepi II's reign. Early years of Pepi II's reign He was traditionally thought to be the son of Pepi I and Queen Ankhesenpepi II, but the South Saqqara Stone annals record that Merenre had a minimum reign of 11 years. Several 6th Dynasty royal seals and stone blocks – the latter of which were found within the funerary temple of Queen Ankhesenpepi II, the known mo ...

Sixth Dynasty
The Sixth Dynasty of ancient Egypt (notated Dynasty VI), along with the Third, Fourth and Fifth Dynasty, constitutes the Old Kingdom of Dynastic Egypt. Pharaohs Known pharaohs of the Sixth Dynasty are listed in the table below. Manetho accords the dynasty 203 regnal years from Teti to Nitocris, while the Turin Canon assigns 181 regnal years, but with three additional kings concluding with Aba – discounting the reigns of the added Eighth Dynasty kings, this is reduced to 155 regnal years. This estimate varies between both scholar and source. History The Sixth Dynasty is considered by many authorities as the last dynasty of the Old Kingdom, although ''The Oxford History of Ancient Egypt'' includes Dynasties VII and VIII as part of the Old Kingdom. Manetho writes that these kings ruled from Memphis, since their pyramids were built at Saqqara, very close one to another. By the Fifth Dynasty, the religious institution had established itself as the dominan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crocidura
The genus ''Crocidura'' is one of nine genus, genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, ''Crocidura'' contains the most species of any mammal genus. The name ''Crocidura'' means "woolly tail", because the tail of ''Crocidura'' species are covered in short hairs interspersed with longer ones. They are found throughout all tropical and temperate regions of the Old World, from South Africa north to Europe, and east throughout Asia, as far east as the Malay Archipelago. One species, the possibly extinct Christmas Island shrew (''C. trichura''), also inhabited Christmas Island. They likely originated in Africa or Anatolia, Asia Minor during the Miocene, spread to Europe by the early Pliocene, and spread to eastern Asia and the Mediterranean by the Pleistocene.
