Lumbricus Badensis
''Lumbricus badensis'' is a type of giant earthworm, a species of annelid. It is endemic to the upper-elevation spruce forests of Germany's Black Forest, where its common name is ''Badischer Riesenregenwurm'' ("giant rainworm of Baden"). It inhabits exclusively the region between the mountains Feldberg and Belchen, and the Wiese Valley at elevations above 1000 m.

Wilhelm Michaelsen
Johann Wilhelm Michaelsen (9 October 1860, Hamburg - 18 February 1937) was a German zoologist who was a world authority on the Oligochaeta which includes the earthworms. He named and described more than a thousand new species. Michaelsen was born to Friedrich Rudolph and Johanna Catharina Ferdinandine née Köhn. In 1887 he commenced work at the Hamburg Zoological Museum, at first as a research assistant. He was later to become ''Hauptkustos'' (chief curator). Alfred Lothar Wegener (1880-1930) was a friend of Michaelsen and made use of his biogeographical work for some of his ideas on plate tectonics. Michaelsen named a species of earthworm after him as ''Wegeneriella'' Michaelsen, 1933. He also collaborated with John Stephenson. Though he also worked in the study of Tunicates and Polychaetes, Michaelsen was best known for his work on Oligochaeta. To that end, he travelled to southern regions of South America, Africa and Australia to investigate the fossil records of ...

Annelid
The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spruce
A spruce is a tree of the genus ''Picea'' (), a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal ( taiga) regions of the Earth. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures ( pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the eastern spru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Forest
The Black Forest (german: Schwarzwald ) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers. Its highest peak is the Feldberg with an elevation of above sea level. Roughly oblong in shape, with a length of and breadth of up to , it has an area of about 6,009 km2 (2,320 sq mi). Historically, the area was known for forestry and the mining of ore deposits, but tourism has now become the primary industry, accounting for around 300,000 jobs. There are several ruined military fortifications dating back to the 17th century. History In ancient times, the Black Forest was known as , after the Celtic deity, Abnoba. In Roman times ( Late antiquity), it was given the name ("Marcynian Forest", from the Germanic word ''marka'' = "border"). The Black Forest probably represented the ...

Baden
Baden (; ) is a historical territory in South Germany, in earlier times on both sides of the Upper Rhine but since the Napoleonic Wars only East of the Rhine. History The margraves of Baden originated from the House of Zähringen. Baden is named after the margraves' residence, in Baden-Baden. Hermann II of Baden first claimed the title of Margrave of Baden in 1112. A united Margraviate of Baden existed from this time until 1535, when it was split into the two Margraviates of Baden-Durlach and Baden-Baden. Following a devastating fire in Baden-Baden in 1689, the capital was moved to Rastatt. The two parts were reunited in 1771 under Margrave Charles Frederick. The restored Margraviate with its capital Karlsruhe was elevated to the status of electorate in 1803. In 1806, the Electorate of Baden, receiving territorial additions, became the Grand Duchy of Baden. The Grand Duchy of Baden was a state within the German Confederation until 1866 and the German Empire u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feldberg (Black Forest)
At the Feldberg in the Black Forest is the highest mountain in Baden-Württemberg, and the highest in Germany outside of the Alps. The local municipality of Feldberg was named after the mountain. Environment The Feldberg is situated southeast of Freiburg im Breisgau and is surrounded by the municipalities of Hinterzarten (northeast), Titisee (east), Menzenschwand (south), Bernau (also south) and Todtnau (southwest). About two kilometres southeast of the summit lies the village of Feldberg (). Between the main peak (, also known as the ''Höchste'' or "Highest", and its subpeak, the Seebuck (), just under away, is a saddle, the ''Grüble'', from which a wide spur, the Baldenweger Buck () branches off. The saddle initially descends gently and then ever more steeply into the valleys on either side. From the Seebuck the Feldberg drops steeply away to the northeast into the Feldsee, a lake of glacial origin at about altitude. Deeply incised valleys run northwest towards F ...

Belchen (Black Forest)
The Belchen, , or Black Forest Belchen (german: Schwarzwälder Belchen) is the fourth-highest summit of the Black Forest after Feldberg, Seebuck and Herzogenhorn. The municipalities of Münstertal, Schönenberg and Kleines Wiesental meet on the summit dome of Belchen which is located in the southwest German state of Baden-Württemberg. Geography The Belchen, with its furrowed, unbroken rock faces, rises 1,000 metres out of the Münstertal valley. Its north face is thus the area of highest relief energy in the German Central Uplands. Even towards the south the mountain drops steeply, its '' schrofen'' slopes descending 800 metres into the valley bowl of the Little Wiese near Neuenweg. The large expanse of rolling plateau in the eastern Black Forest has only survived in small places at the Belchen. Towards the Rhine Plain and the Blauen mountain the western main crest of the southern Black Forest has been cut into narrow ridges as a result of the marked uplift o ...

Wiese (river)
The Wiese is a river, 57.8 kilometres long, and a right-hand tributary of the Rhine in southwest Germany and northwest Switzerland. From its source in Baden-Württemberg in the Southern Black Forest on the mountain of the Feldberg, it flows for a short distance though the county of Breisgau-Hochschwarzwald and then mainly across Lörrach and through numerous settlements including the county town of Lörrach. After crossing the international border, the lower reaches of the river pass through the canton of Basel-Stadt, mainly through the city of Basle and through its district of Kleinbasel before emptying into the Upper Rhine. The valley of the Wiese, which drains a catchment of 455 square kilometres, is called the '' Wiesental'' or Wiese Valley; it is oriented roughly towards the south-west. Its largest tributary is the Little Wiese (''Kleine Wiese'') which approaches from the north. The right-hand Rhine tributary of the Wiese and the left-hand Rhine tributaries of the Bi ...

Humus
In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. It is also used to describe a topsoil horizon that contains organic matter (''humus type'', ''humus form'', or ''humus profile''). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus commonly ranges between eight and fifteen with the median being about twelve. It also significantly affects the bulk density of soil. Humus is amorphous and lacks the "cellular cake structure characteristic of plants, micro-organisms or animals". Description The prim ...
