Johann Heinrich Rudolf Schenck
Johann Heinrich Rudolf Schenck (31 January 1860 – 25 June 1927) was a German botanist who was a native of Siegen. He was a brother to geographer Adolf Schenck (1857–1936). Heinrich Schenck initially studied natural sciences at the University of Bonn (1879–80), then continued his studies in Berlin under August Wilhelm Eichler (1839–1887) and Simon Schwendener (1829–1919). Later he returned to Bonn as a student of Eduard Strasburger (1844–1912), receiving his doctorate in 1884. In 1889 he became a lecturer in Bonn, and in 1896 relocated to the Polytechnic Institute of Darmstadt, where he was appointed director of the botanical garden. Schenck undertook important research involving adaptation of water plants to their underwater environment. He also conducted studies on the ecology, morphology and histology of lianas. In 1886-87 he accompanied Andreas Franz Wilhelm Schimper (1856–1901) on a scientific expedition to Brazil, and in 1908 performed botanical investigations i ...

Botanist
Botany, also called plant science (or plant sciences), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (') meaning " pasture", "herbs" " grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liana
A liana is a long- stemmed, woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. The word ''liana'' does not refer to a taxonomic grouping, but rather a habit of plant growth – much like ''tree'' or '' shrub''. It comes from standard French ''liane'', itself from an Antilles French dialect word meaning to sheave. Ecology Lianas are characteristic of tropical moist broadleaf forests (especially seasonal forests), but may be found in temperate rainforests and temperate deciduous forests. There are also temperate lianas, for example the members of the '' Clematis'' or '' Vitis'' (wild grape) genera. Lianas can form bridges amidst the forest canopy, providing arboreal animals with paths across the forest. These bridges can protect weaker trees from strong winds. Lianas compete with forest trees for sunlight, water and nutrients from the soil. Forests wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1860 Births
Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as forage, feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of bi ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Schenckochloa
''Schenckochloa'' is a monotypic genus of flowering plants belonging to the family Poaceae. It only contains one known species, ''Schenckochloa barbata'' Its native range is north-eastern Brazil. The genus name of ''Schenckochloa'' is in honour of Heinrich Schenck (1860–1927), a German botanist who was a native of Siegen. The Latin specific epithet of ''barbata'' is derived from ''barbatus'' meaning bearded. Both genus and species were first described and published in Candollea Vol.46 on page 243 in 1991. The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service, but they do not list any known species and they note that it could be a possible synonym of ''Gouinia ''Gouinia'' is a genus of Latin American plants in the grass family.Catasus Guerra, L. 1997.

Kamchatka
The Kamchatka Peninsula (russian: полуостров Камчатка, Poluostrov Kamchatka, ) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russia, Russian Federation. The vast majority of the 322,079 inhabitants are ethnic Russians, although about 13,000 are Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980). The Kamchatka peninsula contains the volcanoes of Kamchatka, a World Heritage Site, UNESCO World Heritage Site. Geography Politically, the peninsula forms part of Kamchatka Krai.

Eric Hultén
Oskar Eric Gunnar Hultén (18 March 1894 – 1 February 1981) was a Swedish botanist, plant geographer and 20th century explorer of The Arctic. He was born in Halla in Södermanland. He took his licentiate exam 1931 at Stockholm University and obtained his doctorate degree in botany at Lund University in 1937. In his thesis, he coined the term ''Beringia'' for the ice-age land bridge between Eurasia and North America. From 1945 to 1961, he was a professor and head of the Botany Section at the Swedish Museum of Natural History. In 1953, he was elected to the Royal Swedish Academy of Sciences as member number 977. Hultén travelled extensively in the Scandes Mountains and Siberia, Kamchatka (1920–22 together with his spouse Elsie Hultén, Sten Bergman and René Malaise), the Aleutian Islands and Alaska (1932). He published extensive accounts on the flora of several of these regions and distribution maps of thousands of species. He was the father of the professor of art hist ...

Alpine Vegetation
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens.. Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season. Some alpine plants serve as medicinal plants. Ecology Alpine plants occur in a tundra: a type of natural region or biome that does not contain trees. Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation, it ends at the snow line where snow and ice persist through summer, also known as the Nival Zone. Alpine plants are not ...
