Lilla Sjö (Hästveda Socken, Skåne)
Lilla Sjö is a lake in the Hässleholm Municipality, municipality of Hässleholm in Skåne County, Skåne and is part of the main catchment area of the Helge River. The lake has an area of 0.144 square kilometers and has an elevation of 57.6 meters above sea level. During test fishing, European perch, perch, white bream, Common bream, bream and Northern pike, pike have been caught in the lake.Until the 1940s, the lake was a bathing lake with a sandy bottom and three bathing places: the ladies', the men's and the priest's. However, due to the lack of a functional wastewater treatment plant, non-existent filtration from peat mining at Åbuamossen, and phosphorus and nitrogen leaks from households and agriculture, it became difficult for the lake to survive on its own. There is a 2.6 km long illuminated exercise trail around Lilla Sjö. Additionally, there is an outdoor gym by the lake, which is connected to the exercise trail. History and conservation Lilla Sjö has been l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hässleholm Municipality
Hässleholm Municipality () is a Municipalities of Sweden, municipality in Scania County in southern Sweden. Its seat is located in the city Hässleholm. The present municipality was created in 1974 when the former ''City of Hässleholm,'' itself incorporated in 1914, was amalgamated with seven surrounding municipalities. In 1863, there were 29 local government units, all rural, in the area. The municipal coat of arms was granted in 1920 and registered for the new municipality in 1974. The cross symbolizes the railway junction, which is the origin of the town Hässleholm. The hazelnuts allude to the name ''Hässleholm'', which roughly translates as ''"Hazel-isle"''. Geography At 1,306.27 km2 Hässleholm is the second largest municipality in Skåne County by total area. By land area Hässleholm is the largest in Scania County with 1,268.53 km2 (Kristianstad Municipality short after with 1,246.25 km2), much due to its relatively small water area of 37.74 km2 ...

Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of Sweden
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large ...

Eurasian Carp
The common carp (''Cyprinus carpio''), also known as European carp, Eurasian carp, or simply carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia.Fishbase''Cyprinus carpio'' Linnaeus, 1758/ref>Arkive The native wild populations are considered Vulnerable species, vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been Domestication, domesticated and Introduced species, introduced (see aquaculture) into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family, Cyprinidae. Taxonomy The type subspecies is ''Cyprinus carpio carpio'', native to much of Europe (notably the Danube and Volga Rivers).Jian Feng Zhou, Qing Jiang Wu, Yu Zhen Ye & Jin Gou Tong (2003). Genetic divergence between ''Cyprinus carpio carpio'' and ''Cyprinus carpio haematopterus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tench
The tench or doctor fish (''Tinca tinca'') is a freshwater, fresh- and brackish water, brackish-water fish of the order Cypriniformes found throughout Eurasia from Western Europe including Great Britain, Britain and Ireland east into Asia as far as the Ob River, Ob and Yenisei Rivers. It is also found in Lake Baikal. It normally inhabits slow-moving freshwater habitats, particularly lakes and lowland rivers.B. Whitton (1982). ''Rivers, Lakes and Marshes'' p 163. Hodder & Staughton, London. Taxonomy The tench was first formally Species description, described in as ''Cyprinus tinca'' by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae with its Type locality (biology), type locality given as "European lakes". In 1764 François Alexandre Pierre de Garsault proposed the new monospecific genus ''Tinca'', with ''Cyprinus tinca'' as the type species by absolute tautonymy. The 5th edition of ''Fishes of the World'' classified ''Tinca'' in the subfamily Tincinae, alongside th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Rudd
The common rudd (''Scardinius erythrophthalmus'') is a benthos, bentho-pelagic freshwater Actinopterygii, ray-finned fish belonging to the Family (biology), family Leuciscidae. This species is widely spread in Europe and central Asia, around the basins of the North Sea, North, Baltic Sea, Baltic, Black Sea, Black, Caspian Sea, Caspian and Aral Sea, Aral seas. Identification Morphologically, this species is very similar to the roach (''Rutilus rutilus''), with which it can be easily confused. It can be identified by the yellow eye colour. The eye of the roach has a big red spot above the pupil, that can be more or less conspicuous. The rudd has an upturned mouth allowing it to feed easily at the top of the water. The placement of the dorsal fin is more to the rear which is even visible in very young fish. There are normally only one or two scales between the tip of the pelvic fins and the anal fins, while on the roach there are five. Also the skin of the rudd is yellowish green, w ...

Common Roach
The roach, or rutilus roach (''Rutilus rutilus''), also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera ''Rutilus'', '' Leucos'' and ''Hesperoleucus'', depending on locality. The plural of the term is also roach. Description The roach is a small fish, often reaching no more than about ; maximum length is . Its body has a bluish-silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39–48. The dorsal and anal fins have 12–14 rays. Young specimens have a slender build; older specimens acquire a higher and broader body shape. The roach can often be recognized by the big red spot in the iris above and beside the pupil. Colours of the eye and fins can be very pale, however, in some environments. In Central and Northern Europe, the common roach can most easily be confused with the common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Microcystis Aeruginosa
''Microcystis aeruginosa'' is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. ''Microcystis aeruginosa'' produces numerous congeners of microcystin, with microcystin-LR being the most common. Microcystis blooms have been reported in at least 108 countries, with the production of microcystin noted in at least 79. Characteristics As the etymological derivation implies, ''Microcystis'' is characterized by small cells (of only a few micrometers diameter), which lack individual sheaths. Cells usually are organized into colonies (large colonies of which may be viewed with the naked eye) that begin in a spherical shape, but lose their coherence to become perforated or irregularly shaped over time in culture. Recent evidence suggests one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Main Line
The Southern Main Line () is a long standard gauge electrified railway between Malmö and Katrineholm in Sweden. The trains continue further on to Stockholm Central Station along the Western Main Line and terminate there (at platforms 16–19). The line also connects to other lines, most notably in Malmö the Öresund line to Copenhagen, and in Lund to the West Coast Line towards Gothenburg. History The first parts of the line opened in 1856 between Malmö and Lund, and the last parts in 1874. An unusual route was chosen as the line passed far from many of the bigger towns at the time, such as Hörby and Kristianstad. This was an attempt to "colonize" the countryside and populate it. Another strategic choice was to put it far from the coast to minimize vulnerability to military attacks. A number of new towns sprung up or grew as the line brought access to the area, such as Eslöv and Hässleholm. Initially the route Katrineholm–Nässjö was called ''Eastern Main Line'', whe ...
