Peter Simon Pallas
Peter Simon Pallas Fellow of the Royal Society, FRS FRSE (22 September 1741 – 8 September 1811) was a Prussian zoologist and botanist who worked in Russia between 1767 and 1810. Life and work Peter Simon Pallas was born in Berlin, the son of Professor of Surgery Simon Pallas. He studied with private tutors and took an interest in natural history, later attending the University of Halle and the University of Göttingen. In 1760, he moved to the University of Leiden and passed his doctor's degree at the age of 19. Pallas travelled throughout the Netherlands and to London, improving his medical and surgical knowledge. He then settled at The Hague, and his new system of animal classification was praised by Georges Cuvier. Pallas wrote ''Miscellanea Zoologica'' (1766), which included descriptions of several vertebrates new to science which he had discovered in the Dutch museum collections. A planned voyage to southern Africa and the East Indies fell through when his father reca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fauna Of Iran
The wildlife of Iran include the fauna and flora of Iran. One of the most famous wildlife of Iran is the critically endangered Asiatic cheetah (''Acinonyx jubatus venaticus''), which today survives only in Iran. History The wildlife of Iran first been partly described by Hamdallah Mustawfi in the 14th century who only referred to animals. In the 18th and 19th centuries, Samuel Gottlieb Gmelin and Édouard Ménétries explored the Caspian Sea area and the Talysh Mountains to document Caspian fauna. Several naturalists followed in the 19th century, including Filippo de Filippi, William Thomas Blanford, and Nikolai Zarudny who documented mammal, bird, reptile, amphibian and fish species. Flora More than one-tenth of the country is forested. The most extensive growths are found on the mountain slopes rising from the Caspian Sea, with stands of oak, ash, elm, cypress, and other valuable trees. On the plateau proper, areas of scrub oak appear on the best-watered mountain slopes, and vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meriones (rodent)
''Meriones'' is a rodent genus that includes the gerbil most commonly kept as a pet, ''Meriones unguiculatus''. The genus contains most animals referred to as jirds, but members of the genera ''Sekeetamys'', ''Brachiones'', and sometimes ''Pachyuromys'' are also known as jirds. The distribution of ''Meriones'' ranges from northern Africa to Mongolia. ''Meriones'' jirds tend to inhabit arid regions including clay desert, sandy desert, and steppe, but are also in slightly wetter regions, and are an agriculture, agricultural pest (organism), pest. The genus was named by Johann Karl Wilhelm Illiger, Illiger in 1811, deriving from the Greek word ''μηρος'' (femur). However the name is shared with Greek warrior Meriones (mythology), Meriones in Homer's ''Iliad'' which has brought confusion to the meaning of the scientific names, specially for the popular pet Mongolian gerbil. Description Adult ''Meriones'' species range in size from 9 to 18 cm (head and body), with tails equal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
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 ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Aralkum
The Aralkum Desert is a desert that has appeared since 1960 on the seabed once occupied by the Aral Sea. It lies to the south and east of what remains of the Eastern Basin Aral Sea in Uzbekistan and Kazakhstan. It is currently the youngest desert in the world. History While the level of the Aral Sea has fluctuated over its existence, the most recent level drop since the 1960s was caused by the Soviet Union building massive irrigation projects in the region. The severely reduced inflow caused the water level in the Aral Sea to drop. While the North Aral Sea rose due to the Dike Kokaral, the South Aral Sea kept dropping, thus expanding the size of the desert, until 2010, when the South Aral Sea was partly reflooded. The water level of the South Aral Sea then began to drop again, this time more severely. In August 2021, British polar athlete Rosie Stancer led the first expedition on foot across the Aralkum desert. Stranded boats Before its desertification, the Aral Sea sustaine ...
