Eschach (Neckar)
Eschach (upstream from Horgen also: ''Württembergische Eschach'') is a river of Baden-Württemberg, Germany. It flows into the Neckar south of Rottweil. Geography Source flows The Eschach arises from two spring waters. The longer one is hydrographically classified as its upper course, the much more water-rich one as its third important inflow. Northern headwaters The longest flow path begins today as ''Eschach'' (without name addition), after older name as ''Württembergische Eschach'' or also ''Horgener Eschach''. It has its source at the homestead "Heimliswald" in the district Rötenberg of Aichhalden at an elevation of 699 m above sea level and flows first in southeast direction. After the Eschach has limited the Winzeln-Schramberg Airfield to the west - the municipal area of Fluorn-Winzeln borders there on the left bank - at km 3.258 of its course it is fed from the right side of the Bannmoosgraben. At km 4,7, the Seltenbach also comes from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neckar
The Neckar () is a river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Schwarzwald-Baar-Kreis near Schwenningen in the ''Schwenninger Moos'' conservation area at a height of above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen, Stuttgart, Ludwigsburg, Marbach, Heilbronn and Heidelberg, before discharging on average of water into the Rhine at Mannheim, at above sea level, making the Neckar its 4th largest tributary, and the 10th largest river in Germany. Since 1968, the Neckar has been navigable for cargo ships via 27 locks for about upstream from Mannheim to the river port of Plochingen, at the confluence with the Fils. From Plochingen to Stuttgart, the Neckar valley is densely populated and heavily industrialised, with several well-known companies. Between ...

Habitat Type
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaver
Beavers are large, semiaquatic rodents in the genus ''Castor'' native to the temperate Northern Hemisphere. There are two extant species: the North American beaver (''Castor canadensis'') and the Eurasian beaver (''C. fiber''). Beavers are the second-largest living rodents after the capybaras. They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet and flat, scaly tails. The two species differ in the shape of the skull and tail and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams impound water and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Crayfish
''Austropotamobius torrentium'', also called the stone crayfish, is a European species of fresh water, freshwater crayfish in the family Astacidae. It is mostly found in tributaries of the Danube, having originated in the northern part of the Balkan Peninsula. Description ''A. torrentium'' grows to a length of around , and has a smooth brown carapace, with an untoothed triangular rostrum (anatomy), rostrum; the underside is creamy white. Males have larger claws than females, but females have a noticeably larger abdomen. As in other crayfish, the first two pairs of pleopods are specialised for sperm transfer in males, while the female's pleopods are uniform, and used for brooding egg (biology), eggs. Distribution The distribution of ''A. torrentium'' is centred on the Danube system, extending from the Olt River in Romania upstream to Germany and Switzerland and into parts of the Rhine and Elbe basins. It is widespread in southern Germany, Switzerland, Austria, Hungary, Slovenia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thick Shelled River Mussel
''Unio crassus'', the thick shelled river mussel, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. MolluscaBase eds. (2023). MolluscaBase. Unio crassus Philipsson, 1788. Accessed through: World Register of Marine Species at: https://marinespecies.org/aphia.php?p=taxdetails&id=1044116 on 2023-01-09 ;Subspecies: * † ''Unio crassus jaeckeli'' Modell, 1950 * † ''Unio crassus klemmi'' Modell, 1957 Ecology As part of newly discovered reproductive behaviour, this mollusc crawls up to the edge of the water, exposing its excurrent aperture, and then lets loose a stream of water. The fountain of water often contains glochidia, and it is suggested that this spurting behavior may facilitate dispersal of mussel larvae (video). Decline The thick shelled river mussel declined during the 20th century everywhere in Europe due to deteriorating water quality, habitat fragmentation and host fish limitation.

Brook Lamprey
The brook lamprey (''Lampetra planeri'', also known as the European brook lamprey and the western brook lamprey) is a small European lamprey species that exclusively inhabits freshwater environments. The species is related to, but distinct from, the North American western brook lamprey ('' Lampetra richardsoni''). Description The brook lamprey is a common, non-parasitic species that ranges from North America to northern Europe. Adult brook lampreys measure from . The body is highly elongated and dark blue or greenish above, lightening to yellowish off-white on the sides and pure white on the ventral side. Like all lampreys, these fish lack paired fins and possess a circular sucking disc instead of jaws, which is filled with blunt teeth. They have a single nostril and seven small gill openings on either side behind the eye. The brook lamprey can be told from the closely related river lamprey (''Lampetra fluviatilis'') by the fact that its two dorsal fins are more closely linke ...

European Bullhead
The European bullhead (''Cottus gobio'') is a freshwater fish that is widely distributed in Europe, mainly in rivers. It is a member of the family Cottidae, a type of sculpin. It is also known as the miller's thumb, freshwater sculpin, common bullhead, and cob. The European bullhead is a small demersal fish that lives both in cold, clear, fast-flowing small streams and in middle-sized rivers. It also occurs on gravelly shores of cold lakes. Further, it thrives in diluted brackish water of the Northern Baltic Sea. Description The bullhead has a large broad head and tapering body, large fins and a rounded tail. The eyes are located near the top of the head. To the distinction from the other freshwater sculpin species found in Northern Europe, it can be told from the alpine bullhead ''Cottus poecilopus'' by the fact that the rays of its pelvic fins are of similar lengths while the first and last rays are longer in the alpine bullhead. It can be distinguished from the fourhorn sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Protected Species
European Protected Species (EPS) are species of plants and animals (other than birds) protected by law throughout the European Union. They are listed in Annexes II and IV of the European Habitats Directive. The lists include several hundred species of plants and animals. They do not include any fungi, lichens or birds. European Union states are required under the Habitats Directive to protect the listed species, and for some species (those listed in Annexe II), they are required to designate Special Areas of Conservation (SACs) to protect populations of them. Birds are omitted from the Annexes because the Habitats Directive does not deal with birds – the equivalent bird species are protected separately under the earlier Birds Directive. Many species which are not European Protected Species are nevertheless protected by individual EU states.

Habitats Directive
The Habitats Directive (more formally known as Council Directive 92/43/EEC on the Conservation of natural habitats and of wild fauna and flora) is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised. The Habitats Directive required national governments to specify areas that are expected to be ensuring the conservation of flora and fauna species. This led to the setting up of a network of protected areas across the EU, along with ' Special Areas of Conservation', which together with the existing Special Protection Areas, became the so-called Natura 2000 network established to protect species and habitats. This directive is one of the main pillars of the European Union's system of wildlife and nature conservation, another being the Birds Directive. The Habitats Directive, together with the Birds Directive, are also called th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muschelkalk
The Muschelkalk (German for "shell-bearing limestone"; french: calcaire coquillier) is a sequence of sedimentary rock strata (a lithostratigraphic unit) in the geology of central and western Europe. It has a Middle Triassic (240 to 230 million years) age and forms the middle part of the tripartite Germanic Trias, that give the Triassic its name, lying above the older Buntsandstein and below the younger Keuper. The Muschelkalk (" mussel chalk") consists of a sequence of limestone and dolomite beds. In the past, the time span in which the Muschelkalk was deposited could also be called "Muschelkalk". In modern stratigraphy, however, the name only applies to the stratigraphic unit. Occurrence The name ''Muschelkalk'' was first used by German geologist Georg Christian Füchsel (1722-1773). In 1834, Friedrich August von Alberti included it into the Triassic system. The name indicates a characteristic feature of the unit, namely the frequent occurrence of lenticular banks composed o ...
