Republic Of Artsakh
Artsakh ( ), officially the Republic of Artsakh or the Republic of Nagorno-Karabakh ( ), was a breakaway state in the South Caucasus whose territory was internationally recognised as part of Azerbaijan. Between 1991 and 2023, Artsakh controlled parts of the former Nagorno-Karabakh Autonomous Oblast of the Azerbaijani Soviet Socialist Republic, including its capital Stepanakert. It had been an enclave within Azerbaijan from the 2020 Nagorno-Karabakh war until the 2023 Azerbaijani offensive, when the Azerbaijani military took control over the remaining territory controlled by Artsakh. Its only overland access route to Armenia after the 2020 war was via the Lachin corridor, which was placed under the supervision of Russian peacekeeping forces. The predominantly Armenian-populated region of Nagorno-Karabakh was claimed by both the Azerbaijan Democratic Republic and the First Republic of Armenia when both countries became independent in 1918 after the fall of the Rus ...

Plant Taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various ...

Enclave
An enclave is a territory that is entirely surrounded by the territory of only one other state or entity. An enclave can be an independent territory or part of a larger one. Enclaves may also exist within territorial waters. ''Enclave'' is sometimes used improperly to denote a territory that is only partly surrounded by another state. Enclaves that are not part of a larger territory are not exclaves, for example Lesotho (enclaved by South Africa), and San Marino and Vatican City (both enclaved by Italy) are enclaved sovereign states. An exclave is a portion of a state or district geographically separated from the main part, by some surrounding alien territory. Many exclaves are also enclaves, but an exclave surrounded by the territory of more than one state is not an enclave. The Azerbaijani exclave of Nakhchivan is an example of an exclave that is not an enclave, as it borders Armenia, Iran, and Turkey. Semi-enclaves and semi-exclaves are areas that, except for possessing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Lazzaro Degli Armeni
San Lazzaro degli Armeni (, "Saint Lazarus of the Armenians"; sometimes called Saint Lazarus Island in English; ) is a small island in the Venetian Lagoon which has been home to the monastery of the Mekhitarists, an Armenian Catholic congregation, since 1717. It is one of the two primary centers of the congregation, along with the monastery in Vienna. The islet lies to the southeast of Venice proper and west of the Lido and covers an area of . Settled in the 9th century, it was a leper colony during the Middle Ages, but fell into disuse by the early 18th century. In 1717 San Lazzaro was ceded by the Republic of Venice to Mkhitar Sebastatsi, an Armenian Catholic monk, who established a monastery with his followers. It has since been the headquarters of the Mekhitarists and, as such, one of the world's prominent centers of Armenian culture and Armenian studies. Numerous important publications, such as the first complete dictionary of the Armenian language (1749–69) and the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trabzon
Trabzon, historically known as Trebizond, is a city on the Black Sea coast of northeastern Turkey and the capital of Trabzon Province. The city was founded in 756 BC as "Trapezous" by colonists from Miletus. It was added into the Achaemenid Empire by Cyrus the Great and was later part of the independent Kingdom of Pontus that challenged Rome until 68 BC. Thenceforth part of the Roman and later Byzantine Empire, the city was the capital of the Empire of Trebizond, one of the successor states of the Byzantine Empire after the Fourth Crusade in 1204. In 1461 it came under Ottoman rule. During the early modern period, Trabzon, because of the importance of its port, again became a focal point of trade to Persia and the Caucasus. Today Trabzon is the second largest city and port on the Black Sea coast of Turkey with a population of almost 300,000. The urban population of the city is 330,836 (Ortahisar), with a metropolitan population of 822,270. Name The Turkish name of the city ...

Shushi
Shusha (, ) or Shushi () is a city in Azerbaijan, in the region of Nagorno-Karabakh. Situated at an altitude of 1,400–1,800 metres (4,600–5,900 ft) in the Karabakh mountains, the city was a mountain resort in the Soviet Union, Soviet era. Most sources date Shusha's establishment to the 1750s by Panah Ali Khan, founder of the Karabakh Khanate, coinciding with the foundation of Shusha fortress, the fortress of Shusha. Some attribute this to an alliance between Panah Ali Khan and Melik Shahnazar II, Melik Shahnazar, the local Armenian prince () of Melikdom of Varanda, Varanda. In these accounts, the name of the town originated from a nearby Armenian village called Shosh, Nagorno-Karabakh, Shosh or Shushikent (see for alternative explanations). Conversely, some sources describe Shusha as an important center within the self-governing Armenian melikdoms of Karabakh in the 1720s, and others say the plateau was already the site of an Armenian fortification.Krunk Hayots Ashkha ...

Taxonomists
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolutionary relationships among organisms, both l ...

Caucasus
The Caucasus () or Caucasia (), is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan. The Caucasus Mountains, including the Greater Caucasus range, have conventionally been considered as a natural barrier between Europe and Asia, bisecting the Eurasian landmass. Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is mostly located on the territory of sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleobotany
Paleobotany or palaeobotany, also known as paleophytology, is the branch of botany dealing with the recovery and identification of plant fossils from geological contexts, and their use for the biological reconstruction of past environments ( paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' or ''paleo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of land plants, as well as the study of prehistoric marine photoautotrophs such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological and climate systems, known as paleoecology and paleoclimatology respectively. It is fundamental to the study of green plant development and evolution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
