Caucasian Fir
''Abies nordmanniana'', the Nordmann fir or Caucasian fir, is a fir indigenous to the mountains south and east of the Black Sea, in Turkey, Georgia and the Russian Caucasus. It occurs at altitudes of 900–2,200 m on mountains with precipitation of over 1,000 mm. The current distribution of the Nordmann fir is associated with the forest refugia that existed during the Ice Age at the eastern and southern Black Sea coast. In spite of currently suitable climate, the species is not found in areas of the Eastern Greater Caucasus, which are separated from the Black Sea Coast by more than 400–500 km. Description It is a large evergreen coniferous tree growing to 55–61 m tall and with a trunk diameter of up to 2 m. In the Western Caucasus Reserve, some specimens have been reported to be and even tall, the tallest trees in the Caucasus, Anatolia, the Russian Federation and the continent of Europe. The leaves are needle-like, flattened, 1.8–3.5 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dombay, Karachay-Cherkess Republic
Dombay (russian: Домба́й; krc, Доммай, ''Dommay'') is an urban locality (a resort settlement) under the administrative jurisdiction of the town of republic significance of Karachayevsk in the Karachay-Cherkess Republic, Russia. As of the 2010 Census, its population was 657. Geography Dombay is situated within the Teberda Nature Reserve (''zapovednik'') and is a tourist destination. History Urban-type settlement status was granted to Dombay in 1965. In January 2013, the ski resort made international headlines when a man died from a broken neck and another was badly injured when a Zorb rolled out of control down a mountain, hitting rocks and eventually coming to a stop away on a frozen lake in Dombay. After the incident made international headlines, Russian authorities called for tougher safety laws. Administrative and municipal status Within the framework of administrative divisions, the resort settlement of Dombay is subordinated to the town of repub ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontic Mountains
The Pontic Mountains or Pontic Alps (Turkish language, Turkish: ''Kuzey Anadolu Dağları'', meaning North Anatolian Mountains) form a mountain range in northern Anatolia, Turkey. They are also known as the ''Parhar Mountains'' in the local Turkish language, Turkish and Pontic Greek languages. The term ''Parhar'' originates from a Hittite language, Hittite word meaning "high" or "summit". In ancient Greek, the mountains were called the Paryadres or Parihedri Mountains. Geography The range runs roughly east–west, parallel and close to the southern coast of the Black Sea. It extends northeast into Georgia (country), Georgia, and west into the Sea of Marmara, with the northwestern spur of the Küre Mountains (and their western extension the Akçakoca Mountains) and the Bolu Mountains, following the coast. The highest peak in the range is Kaçkar Dağı, which rises to . The North Anatolian Fault and the Northeast Anatolian Fault, which are east–west-running strike-slip faults, ...

Alexander Von Nordmann
Alexander von Nordmann (24 May 1803 in Ruotsinsalmi (now Kotka), Finland – 25 June 1866 in Helsinki) was a 19th-century Finnish biologist, who contributed to zoology, parasitology, botany and paleontology.Leikola A (2001Nordmann, Alexander von (1803 - 1866) - eläintieteen professori, todellinen valtioneuvosKansallisbiografia. SKS Biografiakeskus Biography Nordmann was a son of an officer of the Russian army at the Ruotsinsalmi fortress, SE Finland. He started academic studies at the Imperial Academy of Turku, and at that time also acted as a curator of the entomological collections. In 1827 he continued studies in Berlin with the famous parasitologist and anatomist Karl Rudolphi. His first major work was a microscopical description of tens of parasitic worms and crustaceans from the eyes and other organs of fishes and other animals, including man. These included the enigmatic monogenean ''Diplozoon paradoxum''. In 1832 he was appointed a professor (teacher) at the Lyceum R ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Conifer Cone
A conifer cone (in formal botany, botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the plant sexuality, reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous plant, herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the cone (geometry), geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stomata
In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere in a process called transpiration. Stomata are present in the sporophyte generation of all land plant groups except liverworts. In vascular plants the number, size and distribution of stomata varies widely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Anatolia
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asian ...
