Rječina
The Rječina (; or ), also known as the Fiumara, is a river in Croatia that flows into the Adriatic Sea at the city of Rijeka (). It is about long, with an average width of . It springs from a cave at an elevation of above sea level, below the high cliff of Kičej Hill (elevation ). Until 1870 the river's spring was below the next hill, Podjavorje, but it collapsed in an earthquake near the village of Klana. The most significant confluents are the Sušica, Lužac, Zala, Zahumčica, Golubinka, Ričinica, and Borovšćica, but they are dry for most of the year. In 1968 a dam Valići was built, creating Lake Valići to facilitate a hydroelectric power plant, HE Rijeka, but destroying the village of the same name in the process. The Rječina flows through a canyon for almost half of its length. In Rijeka, the river branches into two parts: Dead Channel (, the old basin), and the new channel, which was created in the 19th century, when Dead Channel was used as a harbor. The best-k ...

Rijeka (; Fiume ([ˈfjuːme]) in Italian and in Fiuman dialect, Fiuman Venetian) is the principal seaport and the List of cities and towns in Croatia, third-largest city in Croatia. It is located in Primorje-Gorski Kotar County on Kvarner Bay, an inlet of the Adriatic Sea and in 2021 had a population of 107,964 inhabitants. Historically, because of its strategic position and Port of Rijeka, its excellent deep-water port, the city was fiercely contested, especially between the Holy Roman Empire, Venice, Italy and Yugoslavia, changing rulers and demographics many times over centuries.

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures ...

Free State Of Fiume
The Free State of Fiume () was an independent free state that existed from 1920 to 1924. Its territory of comprised the city of Fiume (today Rijeka, Croatia) and rural areas to its north, with a corridor to its west connecting it to the Kingdom of Italy. Fiume gained autonomy for the first time in 1719, when it was proclaimed a free port of the Holy Roman Empire in a decree issued by the Emperor Charles VI. In 1776, during the reign of Empress Maria Theresa, the city was transferred to the Kingdom of Hungary and in 1779 gained the status of within that kingdom. The city briefly lost its autonomy in 1848 after being occupied by Croatian '' ban'' (viceroy) Josip Jelačić but regained it in 1868, when it rejoined the Kingdom of Hungary, again as a . Fiume's status as an exclave of Hungary meant that despite being landlocked, the kingdom had a port. Until 1924, Fiume existed for practical purposes as an autonomous entity with elements of statehood. In the 19th century, the ci ...

Aeshna Cyanea
The southern hawker or blue hawker (''Aeshna cyanea'') is a species of hawker dragonfly. Distribution The species is one of the most common and most widespread dragonflies in Europe. The range in the Western Palearctic covers a large part of Europe, to Scotland and southern Scandinavia in the north and to Italy (without the southwest) and the northern Balkans in the south); the eastern boundary is formed by the Urals and the western by Ireland.

Notonecta Glauca
''Notonecta glauca'', also known as the greater water-boatman or common backswimmer, is a species of aquatic insect in the family Notonectidae. This species is found in large parts of Europe, North Africa, and east through Asia to Siberia and China. In much of its range it is the most common backswimmer species. It is also the most widespread and abundant of the four British water-boatmen. ''Notonecta glauca'' are ''Hemiptera'' (true bug) predators, that are approximately 13–16 mm in length. Females have a larger body size compared to males. These water insects swim and rest on their back (hence their common name "backswimmer" or "water boatman") and are found under the water surface. ''Notonecta glauca'' supports itself under the water surface by using their front legs and mid legs and the back end of its abdomen and rest them on the water surface; They are able to stay under the water surface by water tension, also known as the air-water interface (surface tension). They u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Austropotamobius Pallipes
''Austropotamobius pallipes'' is an endangered European freshwater crayfish, and the only crayfish native to the British Isles. Its common names include white-clawed crayfish and Atlantic stream crayfish.

In France, ''A. pallipes'' is found in streams such as the Mornante and Sellon, two small tributaries of the Dorlay in the Loire department. It is protected as a heritage species. It has also been introduced to Corsica, Liechtenstein, and Portugal (from where it is now extirpated). It was once found across most of Great Britain; however its distribution is rapidly shrinking, and it is recorded in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
