Konin Lakes
The Konin Lakes are a group of lakes forming a long navigable channel in central Poland. The lakes include Pątnowskie Lake, Mikorzyńskie Lake, Gosławskie Lake, Licheńskie Lake and Ślesińskie Lake, connecting the River Warta and Lake Gopło and linked to the Warta-Goplo Canal. The lakes are of particular interest because they receive the water outlets from two power stations and the temperature of the water is significantly raised, supporting a different flora and fauna to other lakes in the region. Water for the two power stations is drawn primarily from Lake Pątnowskie, and discharged via canals to Lake Licheńskie, with other outlets flowing into the other lakes. The cooling scheme varies with the time of year, with Licheńskie, Ślesińskie and Mikorzyńskie being included in June but excluded in October. The total area of the lakes is between , and the greatest depth is . Lake Licheńskie is shallow and shows the greatest temperature variation, reaching a maxim ...

Wikimapia
Wikimapia is a geographic online encyclopedia project. The project implements an interactive "clickable" web map that utilizes Google Maps with a geographically-referenced wiki system, with the aim to mark and describe all geographical objects in the world. Wikimapia was created by Alexandre Koriakine and Evgeniy Saveliev in May 2006. The data, a crowdsourced collection of places marked by registered users and guests, has grown to just under 28,000,000 objects , and is released under the Creative Commons License Attribution-ShareAlike (CC BY-SA). Although the project's name is reminiscent of that of Wikipedia, and the creators share parts of the "wiki" philosophy, it is not a part of the non-profit Wikimedia Foundation family of wikis. Since 2018, following years of declining popularity, the site has gone nearly inactive with the site's owners having been unable to pay for the usage of Google Maps and the site's social media accounts having remained derelict. A study from 2017 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusca
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Macrostomum Rostratum
''Macrostomum rostratum'' is a free-living, hermaphroditic flatworm in the family Macrostomidae, found in freshwater and brackish environments. Description ''Macrostomum rostratum'' is colourless and between in length. There are a pair of small eyes at the anterior end and a longitudinal-slit mouth on the ventral surface just behind these. A short pharynx leads from the mouth to a simple gut. Also on the ventral surface, the female gonopore, which is shaped like a rosette, is in front of the male gonopore and penis which are half way along the flatworm. The posterior end of the worm bears an adhesive plate and can spread out to stick to a surface, and the edge of this region bears rodlike rhabdites (defensive structures) in the tissues. Distribution and habitat ''Macrostomum rostratum'' occurs sporadically in the European coastline in the northeastern Atlantic Ocean, typically in the splash zone in both fresh and salt water. It is present in rock pools at Oxwich Bay and Port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otomesostoma Auditivum
''Otomesostoma auditivum'' is a free-living, hermaphroditic flatworm in the order Proseriata, found in brackish and freshwater environments. It is a palearctic species living in shallow-water coastal habitats, and occurring in some freshwater lakes far from the sea. Taxonomy This flatworm was first described in 1874 by the French zoologist Georges Du Plessis who gave it the name ''Mesostoma auditivum''. Because of its unique characteristics, in 1882 Ludwig von Graff erected the genus '' Otomesostoma'' to accommodate it and it became ''Otomesostoma auditivum''. It is one of only two species in the genus, the other being '' Otomesostoma arovi'', described from Lake Baikal by Timoshkin, Lukhnev and Zaytseva in 2010. Distribution ''Otomesostoma auditivum'' is mainly known from marine and brackish water habitats, but it is also found in freshwater locations. It is a holarctic species and has been recorded from the North Atlantic Ocean and the Baltic Sea, including United States, Gree ...

Predation
Predation is a biological interaction In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species ( interspecific interactio ... where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush predation, ambush or pursuit predation, sometimes after stalking the prey. If the attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blicca Bjoerkna
''Blicca bjoerkna'', alternatively called the white bream or the silver bream, is a European species of freshwater fish in the family Cyprinidae. Distribution ''Blicca bjoerkna'' is distributed across most of Europe and in adjacent Western Asia. The natural distribution, though, excludes peripheral areas such as northern Sweden, northern Finland and Norway, and most parts of the British Isles (except Southern England), as well as the Iberian and Italian peninsulas. Introduced populations occur also in Spain and Italy, for instance. The Asian distribution is in the Caspian Sea and Aral Sea basins and in Anatolian Black Sea drainages. Description Small silver bream are very similar in overall appearance to the immature common, or bronze bream, '' Abramis brama'', but can be distinguished by their larger scales. Counting the scale rows from the front of the dorsal fin to the lateral line and including the lateral line scale, is the most reliable first step in determining the spec ...

Common Bream
The common bream, freshwater bream, bream, bronze bream, carp bream or sweaty bream (''Abramis brama''), is a European species of freshwater fish in the family Cyprinidae. It is now considered to be the only species in the genus ''Abramis''. Range and habitat The common bream's home range is Europe north of the Alps and Pyrenees, as well as the Balkans. They are found as far east as the Caspian Sea, the Black Sea, and the Aral Sea. The common bream lives in ponds, lakes, canals, and slow-flowing rivers. Description The bream is usually long, though some specimens of have been recorded; it usually weighs . Its maximum length is 90 cm (35.5 in),the recorded weight is around 9.1 kg (20 lb). The common bream has a laterally flattened and high-backed body and a slightly undershot mouth. It is a silvery grey colour, though older fish can be bronze-coloured, especially in clear waters. The fins are greyish to black, but never reddish. Similar-looking fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients de ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans ( Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) l ...

Pątnowskie Lake
Pątnowskie Lake is a lake in central Poland known as Jezioro Pątnowskie in Polish. It is located in Konin County in Gmina Ślesin, near the town of Licheń Stary. It is a post-glacial ribbon lake with a weakly developed shoreline. To the north it is connected to Ślesińskie Lake and Mikorzyńskie Lake and forms part of the 32-kilometer navigable Ślesińskie Canal. It is one of several lakes known collectively as the heated Konin Lakes because the water temperature is raised as a result of the outflow received from two power stations. Pątnowskie Lake receives the outflow throughout the year and has a thriving population of fish including common bream, carp, common roach, tench, grass carp, silver carp, bighead carp and zander. It is popular with anglers. With its large area and open shoreline, the lake is used recreationally for sailing and windsurfing Windsurfing is a wind propelled water sport that is a combination of sailing and surfing. It is also referred to as "sai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
