Karl Heinrich Mertens
Karl Heinrich Mertens (Russian: Андрей Карлович Мертенс, 17 May 1796 – 18 September 1830 Kronstadt), was a German botanist and naturalist, and son of the botanist Franz Carl Mertens. Mertens was aboard the Russian vessel ''Senyavin'' under Captain Lieutenant Fedor Petrovich Litke with orders to explore the coasts of Russian America and Asia. This turned out to be one of the most productive voyages of discovery in the nineteenth century. Mertens, ornithologist Baron von Kittlitz, and mineralogist Alexander Postels collected and described over 1 000 new species of animal life, and some 2 500 specimens of plants, algae, and rocks. Shortly after this voyage, Litke and the ''Senyavin'' set out on another scientific expedition to Iceland, the chief scientist being Mertens who died two weeks after the expedition's return to Kronstadt. Cape Mertens (64°32’N, 172°25’W) east of the Chukotka Peninsula at the exit from the Senyavin Straits is named in his ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ctenophore
Ctenophora (; ctenophore ; ) comprise a phylum of marine invertebrates, commonly known as comb jellies, that inhabit sea waters worldwide. They are notable for the groups of cilia they use for swimming (commonly referred to as "combs"), and they are the largest animals to swim with the help of cilia. Depending on the species, adult ctenophores range from a few millimeters to in size. Only 100 to 150 species have been validated, and possibly another 25 have not been fully described and named. The textbook examples are cydippids with egg-shaped bodies and a pair of retractable tentacles fringed with tentilla ("little tentacles") that are covered with colloblasts, sticky cells that capture prey. Their bodies consist of a mass of jelly, with a layer two cells thick on the outside, and another lining the internal cavity. The phylum has a wide range of body forms, including the egg-shaped cydippids with retractable tentacles that capture prey, the flat generally combless platyct ...

Mertensia
''Mertensia'' is a genus of flowering plants in the family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by an increase of pH in the flower tissue. ''Mertensia'' is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped). ''Mertensia'' is native to most of North America and to a large part of Asia from western China to northeastern Russia.Mare Nazaire, Xiao-Quan Wang, and Larry Hufford. 2014. "Geographic origins and patterns of radiation of ''Mertensia'' (Boraginaceae)". ''American Journal of Botany'' 101(1):104-118. . Its center of diversity is in the Rocky Mountains.

René Primevère Lesson
René (''born again'' or ''reborn'' in French) is a common first name in French-speaking, Spanish-speaking, and German-speaking countries. It derives from the Latin name Renatus. René is the masculine form of the name (Renée being the feminine form). In some non-Francophone countries, however, there exists the habit of giving the name René (sometimes spelled without an accent) to girls as well as boys. In addition, both forms are used as surnames (family names). René as a first name given to boys in the United States reached its peaks in popularity in 1969 and 1983 when it ranked 256th. Since 1983 its popularity has steadily declined and it ranked 881st in 2016. René as a first name given to girls in the United States reached its peak in popularity in 1962 when it ranked 306th. The last year for which René was ranked in the top 1000 names given to girls in the United States was 1988. Persons with the given name * René, Duke of Anjou (1409–1480), titular king of Naples ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Kronstadt
Kronstadt (russian: Кроншта́дт, Kronshtadt ), also spelled Kronshtadt, Cronstadt or Kronštádt (from german: link=no, Krone for "crown" and ''Stadt'' for "city") is a Russian port city in Kronshtadtsky District of the federal city of Saint Petersburg, located on Kotlin Island, west of Saint Petersburg, near the head of the Gulf of Finland. It is linked to the former Russian capital by a combination levee-causeway-seagate, the St Petersburg Dam, part of the city's flood defences, which also acts as road access to Kotlin island from the mainland. Founded in the early 18th century by Peter the Great, it became an important international centre of commerce whose trade role was later eclipsed by its strategic significance as the primary maritime defence outpost of the former Russian capital. Kaplan, 1995 The main base of the Russian Baltic Fleet was located in Kronstadt, guarding the approaches to Saint Petersburg. In March 1921, the island city was the site of the Krons ...

Alexander Philipov Postels
Alexander Filippovich Postels (russian: Александр Филиппович Постельс; 24 August 1801 Dorpat – 28 June 1871 Vyborg), was a Baltic German of Russian citizenship naturalist, mineralogist and artist. Postels studied at St.Petersburg Imperial University and in 1826 lectured there on inorganic chemistry. In the 1820s political relations between Russia and the United States were troubled by the extent of Russian territory in North America. Russia intended to enforce its claims by sending two warships to the disputed areas. When the two countries agreed on 54°40′N as the southern limit of Russian claims, Czar Nicolas I changed their orders in 1826 to an extended three-year survey of the Russian-American and Asian coasts. Otto von Kotzebue had returned on 10 July 1826 from his voyage of discovery aboard ''Predpriyatiye''. On 16 August 1826, Captain Lieutenant Fedor Petrovich Litke, sailed on board the Russian vessel ''Senyavin'', accompanied by the '' ...

Friedrich Heinrich, Freiherr von Kittlitz (16 February 1799 – 10 April 1874) was a Prussian artist, naval officer, explorer and naturalist. He was a descendant of a family of old Prussian nobility ("Freiherr" meaning "independent lord" - ranking with a baron). He collected specimens and made illustrations on major expeditions and wrote a few books on his travels. Several species were described on the basis of specimens collected by him and a few are named after him including Kittlitz's plover. Life and work Kittlitz was born in Breslau to Prussian Captain Friedrich (1769-1825) and Henriette Ehrenfried von Diebitsch (1771-1835).
