Jelgava
Jelgava () is a state city in central Latvia. It is located about southwest of Riga. It is the largest town in the Semigallia region of Latvia. Jelgava was the capital of the united Duchy of Courland and Semigallia (1578–1795) and was the administrative center of the Courland Governorate (1795–1918). Jelgava is situated on a fertile plain rising only above mean sea level on the right bank of the river Lielupe. At high water, the plain and sometimes the town as well can be flooded. It is a railway center, and is also a host to the Jelgava Air Base. Its importance as a railway centre can be seen by the fact that it lies at the junction of over 6 railway lines connecting Riga to Lithuania, eastern and western Latvia, and Lithuania to the Baltic Sea. Name Until 1917, the city was officially referred to as Mitau. The name of Jelgava is believed to be derived from the Livonian word ''jālgab'', meaning "town on the river."

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleksander Czekanowski
Aleksander Piotr Czekanowski, or Aleksandr Lavrentyevich Chekanovsky (, 24 February 1833 – 30 October 1876) was a Polish geologist and explorer of Siberia during his exile after participating in the January Uprising. He took part in and later led several expeditions, surveying and mapping the geology of Eastern Siberia. He was released from exile in 1875, and in 1876 took up the post of custodian in the Mineralogical Museum of the Academy of Sciences. Biography Aleksander Czekanowski was born on 12 February 1833 in Krzemieniec, Volhynia. His father Wawrzyniec ran a boarding house and was an honorary assistant in a zoological office at a high school. Shortly after the birth of Alexander, his family moved to Kiev. In 1850 Alexander began studying medicine at the Faculty of Medicine in Kiev. While there he also attended lectures on natural science and participated in local field trips during which he developed a strong interest in geology. After receiving a doctor's diploma in 185 ...

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Gustav Radde
Gustav Ferdinand Richard Radde (27 November 1831 – 16 March 1903) was a German naturalist and Siberian explorer. Radde's warbler and several other species are named after him. Biography Radde was born in Danzig, the son of a schoolmaster. He had little formal education, and began a career as an apothecary. At an early age he was influenced by Anton Menge and became increasingly interested in natural history, and in 1852 he gave up his career and spent two years in the Crimea with the botanist Christian von Steven, collecting both plants and animals. He made further trips to southern Russia with Johann Friedrich von Brandt and Karl Ernst von Baer. He was botanist and zoologist on the East Siberian Expedition of 1855, led by the astronomer Ludwig Schwarz. In 1864 he eventually settled in Tbilisi. In the same year he explored the region surrounding Mount Elbrus, the highest mountain in the Western Palearctic. As well as collecting many plants he recorded the languages, ball ...

Caspian Sea
The Caspian Sea is the world's largest inland body of water, described as the List of lakes by area, world's largest lake and usually referred to as a full-fledged sea. An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east), an area approximately equal to that of Japan, with a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The name of the Caspian Sea is derived from the ancient Iranian peoples, Iranic Caspians, Caspi people. The sea stretches from north to south, with an average width of . Its gr ...

Herniaria
''Herniaria'' is a genus of flowering plants in the family Caryophyllaceae known generally as ruptureworts. They are native to Eurasia and Africa but several species have been widely introduced to other continents. These are flat, mat-forming annual herbs. The genus gets its scientific and common names from the once-held belief that species could be used as an herbal remedy for hernias.

Phytogeography
Phytogeography (from Greek φυτόν, ''phytón'' = "plant" and γεωγραφία, ''geographía'' = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges (at both large and small scales, see species distribution) to the factors that govern the composition of entire communities and floras. Geobotany, by contrast, focuses on the geographic space's influence on plants. Fields Phytogeography is part of a more general science known as biogeography. Phytogeographers are concerned with patterns and process in plant distribution. Most of the major questions and kinds of approaches taken to answer such questions are held in common between phyto- and zoogeographers. Phytogeography in wider sense (or geobo ...
