Barbary Ground Squirrel
The Barbary ground squirrel (''Atlantoxerus getulus'') is a species of rodent in the family Sciuridae. It is monotypic within the genus ''Atlantoxerus''. It is endemic to the Atlas mountains in Morocco and some parts in Algeria, and has been introduced into the Canary Islands. Its natural habitats are subtropical or tropical dry shrubland, temperate grassland and rocky areas where it lives colonially in burrows. It was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. Description The Barbary ground squirrel is a small species growing to a length of between with a bushy tail of a similar length. It weighs up to and has short wiry hair. The general colour is greyish-brown or reddish-brown and there is a white stripe running along each side, and sometimes another along the spine. The belly is paler grey and the tail is longitudinally barred in black and grey.Thorington, R. W. Jr. and R. S. Hoffman. 2005. Family Sciuridae. pp. 754 ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Mammals Described In 1758
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they Genetic divergence, diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant taxon, extant species of mammals have been described divided into 29 Order (biology), orders. The largest Order (biology), orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, Mole (animal), moles, shrews, and others).

Rodents Of North Africa
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose ...

Xerini
Xerini is a tribe of ground squirrels occurring in Africa and Asia. With the tribes Marmotini (Holarctic ground squirrels) and Protoxerini (African tree squirrels), they form the subfamily Xerinae. There are five living genera—'' Xerus'', the unstriped ground squirrel; '' Euxerus'', the striped ground squirrel; ''Geosciurus'', the Cape and mountain ground squirrels; ''Atlantoxerus'', containing the living Barbary ground squirrel of North Africa and some extinct species; and ''Spermophilopsis'', containing the long-clawed ground squirrel of Central Asia. The squirrels live in open woodlands, grasslands, or rocky country. They are diurnal and terrestrial, living in burrows. Their diet is roots, seeds, fruits, pods, grains, insects, small vertebrates and bird eggs. They live in colonies similar to North American prairie dogs, and have similar behavior. If kept as pets, they run free as house cats do, otherwise farmers consider them pests. Breeding in South African ground squirrels ...

Essaouira
Essaouira ( ; ar, الصويرة, aṣ-Ṣawīra; shi, ⵜⴰⵚⵚⵓⵔⵜ, Taṣṣort, formerly ''Amegdul''), known until the 1960s as Mogador, is a port city in the western Moroccan region of Marakesh-Safi, on the Atlantic coast. It has 77,966 inhabitants as of 2014. The foundation of the city of Essaouira was the work of the Moroccan 'Alawid sultan Mohammed bin Abdallah, who made an original experiment by entrusting it to several renowned architects in 1760, in particular Théodore Cornut and Ahmed al-Inglizi, who designed the city using French captives from the failed French expedition to Larache in 1765, and with the mission of building a city adapted to the needs of foreign merchants. Once built, it continued to grow and experienced a golden age and exceptional development, becoming the country's most important commercial port but also its diplomatic capital between the end of the 18th century and the first half of the 19th century.

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Argan
''Argania'' (Tashelhit: ⴰⵔⴳⴰⵏ ''Argan'') is a genus of flowering plants containing the sole species ''Argania spinosa'', known as argan, a tree endemic to the calcareous semidesert Sous valley of southwestern Morocco and to the region of Tindouf in southwestern Algeria. Argan trees grow to high and live up to approximately 200 years. They are thorny, with gnarled trunks and wide spreading crown. The crown has a circumference of about and the branches lean towards the ground. The leaves are small, long, and oval with a rounded apex. The flowers are small, with five pale yellow-green petals; flowering in April. The fruit is long and broad, with a thick, bitter peel surrounding a sweet-smelling but unpleasantly flavored layer of pulpy pericarp. This surrounds the very hard nut, which contains one (occasionally two or three) small, oil-rich seeds. The fruit takes over a year to mature, ripening in June to July of the following year.

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffic ...

Xerus Erythropus
The striped ground squirrel (''Euxerus erythropus'') is a species of squirrel native to Africa. It was first described by Geoffroy in 1803, but the original publication may be unavailable, so that the binomial authority is today more often cited as " Desmarest, 1817". There are six subspecies. It is a moderately large ground squirrel with sandy-brown or dark-brown fur with a white lateral stripe and whitish underparts. Adults live alone or in pairs in a simple burrow with a central nest, foraging, mostly on the ground, for seeds, nuts and roots, and caching excess food under stones. This is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Description Striped ground squirrels are moderately large ground squirrels, ranging from in length, with a tail that, at , is nearly as long as the body. Adults weigh between . They have a coat of short, bristly fur, and are pale sandy to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
