Lake Liepāja
Lake Liepāja ( lv, Liepājas ezers, formerly Lake Libava, lv, Libavas ezers) is the fifth-largest lake in Latvia, located near Liepāja in the Liepāja District. The total area of the lake is 37.15 km2, and it has a length of 16.2 km, average depth of 2.0 m, and a shoreline of 44.6 km. Lake Liepāja is a pod-shaped shallow eutrophic coastal lake with extensive areas of emergent vegetation (Phragmites, Typha, Scirpus, Sparganium), surrounded by seasonally flooded meadows and arable land. Polders and dams enclose most of the wetland area. The lake has 14 species of fish: pike, roach, perch, bream, crucian carp, tench, eel, vimba, burbot, carp, zander, smelt, bitterling, and rudd. In May only licensed fishing is allowed. The price of a licence is 10 LVL (about $20). From 1977 to 1999 the lake was an ornithological preserve with 2 species of birds: swans and ducks. Since 2004 the lake has been included on the European Union Natura 2000 protected territories list. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bārta
Bārta (in Latvian), also named Bartuva (in Lithuanian), is a river in western Lithuania and Latvia. It originates in the Plungė district, 3 km to north of Lake Plateliai. The Bārta flows in a northwesterly direction, passing through the Skuodas district and the city of Skuodas, before entering Latvia. The Bārta flows into Liepāja lake, which is connected with the Baltic Sea. In its upper courses the valley formed by the Bārta is deep and narrow, while in its lower courses it is much wider. Bārta's main tributaries are the Eiškūnas, Erla, Luoba, Apšė, Vārtāja. The etymology of the name ''Bārta''/''Bartuva'' is unclear. Kazimieras Būga it derived from the Baltic tribe name ''Bartians The Bartians (also ''Barthi'', ''Barthoni'', ''Bartens'', or ''Barti'') were an Old Prussian tribe who were among the last natives following a pre-Christian religion before the Northern Crusades forced their conversion to Christianity at the cost ...''.

Grove (nature)
A grove is a small group of trees with minimal or no undergrowth, such as a sequoia grove, or a small orchard planted for the cultivation of fruits or nuts. Other words for groups of trees include ''woodland'', ''woodlot'', ''thicket'', and ''stand''. The main meaning of " grove" is a group of trees that grow close together, generally without many bushes or other plants underneath. It is an old word in the English language, with records of its use dating as far back as the late 9th century. The word's true origins are unknown; the word, or a related root, cannot be found in any other Germanic language. Naturally-occurring groves are typically small, perhaps a few acres at most.In contrast, orchards, which are normally intentional planting of trees, may be small or very large, like the apple orchards in Washington state, and orange groves in Florida. Historically, groves were considered sacred in pagan, pre-Christian Germanic and Celtic cultures. Helen F. Leslie-Jacobsen a ...

Natura 2000
Natura 2000 is a network of nature protection areas in the territory of the European Union. It is made up of Special Areas of Conservation and Special Protection Areas designated under the Habitats Directive and the Birds Directive, respectively. The network includes both terrestrial and Marine Protected Areas. History In May 1992, the governments of the European Communities adopted legislation designed to protect the most seriously threatened habitats and species across Europe. The Habitats Directive complements the Birds Directive adopted earlier in 1979 and together they make up the Natura 2000 network of protected areas. The Birds Directive requires the establishment of Special Protection Areas for birds. The Habitats Directive similarly requires Sites of Community Importance which upon the agreement of the European Commission become Special Areas of Conservation to be designated for species other than birds, and for habitat types (e.g. particular types of forest, grassland ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swan
Swans are birds of the family (biology), family Anatidae within the genus ''Cygnus''. The swans' closest relatives include the goose, geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe (biology), tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life, although "divorce" sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of bird egg, eggs in each :wikt:clutch, clutch ranges from three to eight. Etymology and terminology The English word ''swan'', akin to the German language, German , Dutch language, Dutch and Swedish language, Swedish , is derived from Indo-European root ' ('to sound, to sing'). Young swans are kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithological
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latvian Lats
The lats (plural: ''lati'' or ''latu'' (if the number can be divided by 10), ISO 4217 currency code: LVL or 428) was the currency of Latvia from 1922 until 1940 and from 1993 until it was replaced by the euro on 1 January 2014. A two-week transition period during which the lats was in circulation alongside the euro ended on 14 January 2014. The lats is abbreviated as ''Ls'' and was subdivided into 100 ''santīmi'' (singular: ''santīms''; from French ''centime''), abbreviated as an ''s'' after the santīm amount. The Latvian lats has been recognized as one of the 99 entries of the Latvian Culture Canon. First lats, 1922–1940 The first lats (symbol: ℒ𝓈) was first introduced on 3 August 1922, replacing the Latvian ruble at a rate of ℒ𝓈 1 = Rbls 50. The lats was pegged against the gold standard from its introduction until 1940. On 17 June 1940, Latvia was occupied by the USSR. After the dismantling of the Bank of Latvia and its replacement with the Latv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudd
''Scardinius'' is a genus of ray-finned fish in the family Cyprinidae commonly called rudds. Locally, the name "rudd" without any further qualifiers is also used for individual species, particularly the common rudd (''S. erythrophthalmus''). The rudd can be distinguished from the very similar roach by way of the rudd's upturned mouth, allowing it to pick food items such as aquatic insects from the surface of the water with minimal disturbance. The Greek rudd (''S. graecus'') is a similar fish, about 40 cm long. It occurs only in the southern tip of the Greek mainland. It lives in lakes and slow-flowing rivers, forming large schools. It spawns around April–June among underwater plants in shallow water. It feeds on small crustaceans, the larvae and pupae of insects, and on plant material. The majority of its food is taken at or near the surface of the water. The fish is not usually found in deep water. Very little is known about the biology of this species. It is important ...

Smelt (fish)
Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large Shoaling and schooling, schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt (''Hypomesus transpacificus'') found in the Sacramento Delta of California, and the eulachon (''Thaleichthys pacificus'') found in the Nort ...
