Lake Varese
Varese Lake () is a lake of glacial origin in Lombardy, in the north of Italy. It has an area of 14.5 km², a medium depth of 11 m, and a maximum depth of 23 m. It hosted the Canoeing European Championships in 2012, the World Rowing Master Regatta in 2013, the World Rowing Under 23 Championships in 2014, the second Canoeing World Championship in 2015 and the World Rowing Under 23 / Under 19 Championships in 2022. Formation The birth of Lake Varese dates back to about 15,000 years ago, at the same time as that of nearby Lake Maggiore, when the retreat of the Verbano glacier created the large basin in which the city and its lake are located today, which at the time had a much larger surface and included much of the surrounding lakes. The Waters The lake is currently (since 2015) not suitable for swimming. Flora and Fauna Flora Lying between the basins of Lake Varese and Lake Comabbio, the Palude Brabbia, covering 459 hectares, is a nature reserve that protects one ...

Province Of Varese
The province of Varese () is a Provinces of Italy, province in the Lombardy region of Italy. Its capital is the city of Varese (population of 80,857 inhabitants), but its largest city is Busto Arsizio. The headquarters of AgustaWestland, the company merged into Leonardo S.p.A., Leonardo since 2016 and the world's largest producer of helicopters, is based in Samarate, a ''comune'' (municipality) of the province. The province contains 139 ''comuni'' (: ''comune''). As of 2015, it has a population of 889,410 inhabitants over an area of . History In Roman times, the fortified settlements of Castelseprio (archaeological park), Castelseprio and the port of Angera were of high importance in the region. The Visconti of Milan, House of Visconti conquered the region in the 13th century and completely destroyed Castelseprio. The House of Visconti used the land for agricultural purposes and as part of the territories of Milan. During this Visconti rule, Varese became prosperous due to high ...

Tufted Duck
The tufted duck (or tufted pochard) (''Aythya fuligula'') is a small diving duck with a population of nearly one million birds, found in northern Eurasia. They are partially migratory. The scientific name is derived from Ancient Greek , an unidentified seabird mentioned by authors such as Hesychius and Aristotle, and Latin 'soot' and ' 'throat'. It is a game bird. Taxonomy The tufted duck was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas fuligula''. He cited the Swiss naturalist Conrad Gessner who in 1555 had used the identical name ''Anas fuligula'' in his '' Historiae animalium''. Linnaeus specified the type locality as Europe but in 1761 restricted it to Sweden. The tufted duck is now one of 12 species placed in the genus '' Aythya'' that was introduced in 1822 by the German naturalist Friedrich Boie. The genus name is from Ancient Greek ''aithuia'', an unidentified se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterways Of Italy
A waterway is any navigable body of water. Broad distinctions are useful to avoid ambiguity, and disambiguation will be of varying importance depending on the nuance of the equivalent word in other ways. A first distinction is necessary between maritime shipping routes and waterways used by inland water craft. Maritime shipping routes cross oceans and seas, and some lakes, where navigability is assumed, and no engineering is required, except to provide the draft for deep-sea shipping to approach seaports ( channels), or to provide a short cut across an isthmus; this is the function of ship canals. Dredged channels in the sea are not usually described as waterways. There is an exception to this initial distinction, essentially for legal purposes, see under international waters. Where seaports are located inland, they are approached through a waterway that could be termed "inland" but in practice is generally referred to as a "maritime waterway" (examples Seine Maritime, Loire ...

Subalpine Lakes Of Italy
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in ...

Lakes Of Lombardy
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 ...

List Of Lakes Of Italy
The following is a list of lakes of Italy. The lakes of Italy can be distinguished, depending on their location within the national territory, between Alpine foothills, pre-alpine, north-western, Apennine Mountains, Apennine, Sicily, Sicilian and Sardinian, in addition to lagoons and coastal lakes. They are generally named after the surrounding towns and often their capacity has been increased with the construction of dams, in order to create large water reserves to be used for the Hydroelectricity in Italy, production of electricity. There are more than 1000 lakes in Italy, the largest of which is Lake Garda, Garda (). The Italian Lakes, pre-alpine lakes are the largest and most important because they constitute capacious basins, in which the alpine rivers restrain their impetus and purify their waters, depositing the transported materials. They also affect the Climate of Italy, local climate, mitigating it. Their waters fill the bottom of long valleys that flow into the Po Valley ...

Italian Lakes
The Italian Lakes (, lit. "great pre-alpine lakes") are a group of large lakes lying on the south side of the Alps, in the basin of the river Po and the Mediterranean Sea. As their name suggests, they are essentially located in northern Italy; however, they are also partly located in southern Switzerland. They are all glacial lakes that formed after the retreat of the glaciers at the end of the last ice age. The group is composed of (from west to east): Lake Orta, Lake Maggiore, Lake Varese, Lake Lugano, Lake Como, Lake Iseo, Lake Idro and Lake Garda. The three largest are all well over 100 km2; they are: Lake Garda (largest in Italy), Lake Maggiore (largest in southern Switzerland) and Lake Como (deepest in Italy). The lakes are located in the Italian regions of Piedmont, Lombardy, Veneto and Trentino-Alto Adige/Südtirol, and in the Swiss canton of Ticino. They are all located at least partly in Italy, while two of them (Maggiore and Lugano) are partly in Switzerl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Heron
The purple heron (''Ardea purpurea'') is a wide-ranging heron species. It breeds in Africa, central and southern Europe, and southern and eastern Palearctic. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements. It is similar in appearance to the more common grey heron but is slightly smaller, more slender and has darker plumage. It is also a more evasive bird, favouring densely vegetated habitats near water, particularly reed beds. It hunts for a range of prey including fish, rodents, frogs and insects, either stalking them or standing waiting in ambush. Purple herons are colonial breeders and build a bulky nest out of dead reeds or sticks close to the water' edge among reeds or in dense vegetation. About five bluish-green eggs are laid and are incubated by both birds. The young hatch about four weeks later and fledge six weeks a ...

Bittern
Bitterns are birds belonging to the subfamily Botaurinae of the heron family Ardeidae. Bitterns tend to be shorter-necked and more secretive than other members of the family. They were called ''hæferblæte'' and various iterations of ''raredumla'' in Old English; the word "bittern" came to English from Old French ''butor'', itself from Gallo-Roman ''butitaurus'', a compound of Latin ''būtiō'' (buzzard) and ''taurus'' (bull). Bitterns usually frequent reed beds and similar marshy areas and feed on amphibians, reptiles, insects, and fish. Bitterns, like herons, egrets, and pelicans, fly with their necks retracted, unlike the cranes, storks, ibises and spoonbills, and geese A goose (: geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera '' Anser'' (grey geese and white geese) and ''Branta'' (black geese). Some members of the Tadorninae subfamily (e.g., Egyp ... which fly with necks extended and outstretched. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heron
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 75 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus ''Botaurus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, ''Ardea (genus), Ardea'' and ''Egretta''. Similarly, the relationships of the genus, genera in the family are not completely resolved. However, one species formerly considered to c ...

Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus '' Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willows
Willows, also called sallows and osiers, of the genus ''Salix'', comprise around 350 species (plus numerous hybrids) of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicin, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, and roots readily sprout from aerial parts of the plant. Leave ...
