Eichener See
The Eichener See ("Lake Eichen"), known in the Alemannic dialect as the Eiemer See, near Eichen in the Baden-Württemberg county of Lörrach is a periodic (''astatic'') karst lake in the Southern Black Forest in Germany. The lake, which only contains water when there is a high water table, lies in a hollow, a muschelkalk- karst basin. It has no surface inflow, its outflows are partly subterranean and partly through evaporation. Location The Eichener See lies in the Southern Black Forest Nature Park on the northeastern perimeter of the Dinkelberg ridge between the nearby village of Eichen to the west, which is part of the municipality of Schopfheim, the municipality of Hasel to the east-northeast and the town of Wehr to the southeast. It is located 2.5 km west of Erdmanns Cave (''Hasler Höhle'') in a shallow valley around 350 metres south of the Bundesstraße 518. Geology and hydrology Geologically it is a doline which is periodically filled with water, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landkreis Lörrach
In all German states, except for the three city states, the primary administrative subdivision higher than a ''Gemeinde'' (municipality) is the (official term in all but two states) or (official term in the states of North Rhine-Westphalia and Schleswig-Holstein). Most major cities in Germany are not part of any ''Kreis'', but instead combine the functions of a municipality and a ''Kreis''; such a city is referred to as a (literally "district-free city"; official term in all but one state) or (literally "urban district"; official term in Baden-Württemberg). ''(Land-)Kreise'' stand at an intermediate level of administration between each German state (, plural ) and the municipal governments (, plural ) within it. These correspond to level-3 administrative units in the Nomenclature of Territorial Units for Statistics (NUTS 3). Previously, the similar title ( Imperial Circle) referred to groups of states in the Holy Roman Empire. The related term was used for similar admi ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100- metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, ...

Special Area Of Conservation
A Special Area of Conservation (SAC) is defined in the European Union's Habitats Directive (92/43/EEC), also known as the ''Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora''. They are to protect the 220 habitats and approximately 1,000 species listed in annex I and II of the directive which are considered to be of European interest following criteria given in the directive. They must be chosen from the Sites of Community Importance by the member states and designated SAC by an act assuring the conservation measures of the natural habitat. SACs complement Special Protection Areas and together form a network of protected sites across the European Union called Natura 2000. This, in turn, is part of the Emerald network of Areas of Special Conservation Interest (ASCIs) under the Berne Convention. Assessment methodology in the United Kingdom Prior to being designated as a Special Area of Conservation (SAC), sites have been assessed under a two-stage pro ...

Natural Monument
A natural monument is a natural or natural/cultural feature of outstanding or unique value because of its inherent rarity, representative of aesthetic qualities or cultural significance. Under World Commission on Protected Areas guidelines, natural monuments are level III, described as: :"Areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine cavern, geological feature such as a cave or even a living feature such as an ancient grove. They are generally quite small protected areas and often have high visitor value." This is a lower level of protection than level II (national parks) and level I (wilderness areas). The European Environment Agency's guidelines for selection of a natural monument are: * The area should contain one or more features of outstanding significance. Appropriate natural features include waterfalls, caves, craters, fossil beds, sand dunes and marine features, along with unique or representative fauna and flo ...

Capsized
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, , loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable inverted. Vessels of this design are called self-righting. Small vessels In dinghy sailing, a practical distinction can be made between being knocked down (to 90 degrees; on its beam-ends, figuratively) which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy are occasi ...

Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of plo ...

Fairy Shrimp
Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes and Antarctic ice. They are usually long (exceptionally up to ). Most species have 20 body segments, bearing 11 pairs of leaf-like ''phyllopodia'' (swimming legs), and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families. Description The body of a fairy shrimp is elongated and divided into segments. The whole animal is typically long, but one species, '' Branchinecta gigas'' does not reach sexual maturity until it reaches long, and can grow to long. The exoskeleton is thin and fl ...

Tanymastix Lacunae
''Tanymastix stagnalis'' is a species of Anostraca (fairy shrimp) that lives in temporary pools across Europe. It may reach up to in some areas and has 11 pairs of bristly, flattened appendages. It swims upside-down and filters food particles from the water. It is the only species of Anostraca in Ireland, having been discovered in Rahasane turlough in 1974. Description ''Tanymastix stagnalis'' has a pair of stalked eyes, and 11 pairs of thoracic appendages, called ''phyllopodia''. The abdomen bears no appendages except for the caudal furca and the external genitalia. In the male the genitalia are a pair of retractable hemipenes, while the female has a brood pouch with two spines. The antennae are also sexually dimorphic, being prehensile in males. At the end of the abdomen, a caudal furca is made up of two red ''cercopods'', which are long, thin and setose. Reports of the size of ''Tanymastix stagnalis'' vary. In Spain, it is reported to reach lengths of , while Macedonia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent wood, woody stems above ground. This broad category of plants includes many perennial plant, perennials, and nearly all Annual plant, annuals and Biennial plant, biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. Glossary of botanical terms#scarious, scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentatio ...
