Paul Graebner
Carl Otto Robert Peter Paul Graebner (29 June 1871 in Aplerbeck – 6 February 1933 in Berlin) was a German botanist. In 1895 he obtained his doctorate in Berlin, successively working as an assistant and then as curator (1904) at the botanical gardens. During the 1890s he performed botanical investigations in Jerichower Land and Vorharz with Paul Ascherson (1834–1913). He later became a professor at the Botanical Garden and Museum in Berlin-Dahlem, from where he conducted floristic and phytogeographical research.

Aplerbeck
Aplerbeck is a borough (''Stadtbezirk'') of the city of Dortmund in the Ruhr district of North Rhine-Westphalia, Germany. Since 1929, it has been a suburb of Dortmund, located in the city's south-east. The river Emscher, a tributary of the Ruhr (river), Ruhr, crosses Aplerbeck. Aplerbeck was first documented as a village in 899. The place is associated with the death of two martyrs Two Ewalds, both named Ewald in the 7th century, according to the Golden Legend. Aplerbeck was the location of mining and heavy industry as part of the Ruhr from the 19th century to 1926, resulting in a larger population and the building of a representative town hall and a larger church. A psychiatric hospital of regional importance, founded in 1890, is still in operation, now as . History The first document mentioning Aplerbeck, then ''Afaldrabechi'', is a founding document (''Stiftungsurkunde'') of 899, a term containing "apple" and "creek". According to the Golden Legend, two missionaries, the Two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparganiaceae
Sparganiaceae is a family of flowering plants. Such a family was previously recognized by most taxonomists. The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes this family, and assigns it to the order Poales in the clade commelinids, in the monocots. The family consists of only one genus ''Sparganium'' of fewer than two dozen species, perennial plants of wet habitats. By the APG III system of 2009, ''Sparganium'' had been found to be fairly closely related to '' Typha'', and so was placed with that genus in family Typhaceae. The Cronquist system, of 1981, also recognized such a family and placed it in the order Typhales in the subclass Commelinidae in class Liliopsida in division Magnoliophyta. The Wettstein system A system of plant taxonomy, the Wettstein system recognised the following main groups, according to Richard Wettstein's ''Handbuch der Systematischen Botanik'' (1901–1924). 3rd edition (1924) Outline Synopsis * Flagellatae p.& ...

Scientists From North Rhine-Westphalia
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Moorland
Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland, nowadays, generally means uncultivated hill land (such as Dartmoor in South West England), but also includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath, although experts disagree on what precisely distinguishes these types of vegetation. Generally, moor refers to highland and high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats mostly occur in tropical Africa, northern and western Europe, and neotropical South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland also bears a relationship to tundra (where the subsoil is permafros ...

Heath
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource management ( ...

Plantesamfund
''Plantesamfund - Grundtræk af den økologiske Plantegeografi'', published in Danish in 1895 by Eugen Warming, and in English in 1909 as ''Oecology of Plants: An Introduction to the Study of Plant Communities'', by Warming and Martin Vahl, was the first book to be published having the word ecology in its title. The book has had a lasting impact on the field of ecology, particularly in its German translation soon after its initial publication, and in its expanded and revised English translation. The book was based on Warming's lectures on plant geography at the University of Copenhagen. It gives an introduction to all major biomes of the world. Its aim was to explain how nature solved similar problems (drought, flooding, cold, salt, herbivory) in similar way, despite using very different raw material (species of different descent) in different regions of the world. * Warming, E.

Typhaceae
The Typhaceae () are a family of flowering plants, sometimes called the cattail family. The botanical name for the family has been recognized by most taxonomists. Description Members can be recognized as large marsh herbs with alternate two-ranked leaves and a brownish compact spike of unisexual flowers. The plants have creeping rhizomes. The male flowers either lack a perianth or have six scales. They may also have club shaped threads or wedge or spatula shaped scales that are intermingled wit the flowers. They have between two and seven stamens. The female flowers have a perianth of fine hairs or scales. These may be accompanied by slender bracteoles. The ovary is one chambered and contains a single pendulous ovule. The style is simple and the stigma simple and long. The fruit may or may not be stalked and the pericarp may be thick or thin. The seeds are endospermous with a cylindric embryo. Fossils The earliest fossils, including pollen and flowers, have been recovered fro ...

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...
