Lake Pamvotida
Lake Pamvotida or Pamvotis ( el, Λίμνη Παμβώτιδα/Παμβώτις), commonly also Lake of Ioannina ( el, Λίμνη των Ιωαννίνων, ''Limni ton Ioanninon'') is the largest lake of Epirus, located in the central part of the Ioannina regional unit in northern Greece. The regional capital Ioannina to the west and the town of Perama to the north are urban settlements fringing the lake while the remaining of its periphery is composed of farmland. The lake features small fishing ports and a boating port. There is a regular boat service to the Ioannina Island. The Greek National Road 6 surrounds the northern half of the lake. Geography Lake Pamvotida is situated at 470 m elevation, south of the Mitsikeli mountains. It is fed by several small rivers. It has no surface outflow, but it is drained through karstic sinkholes towards the rivers Arachthos, Louros and Kalamas. In 1960 a tunnel and ditch were constructed that drain from the northern end of the lake t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epirus (region)
Epirus (; el, Ήπειρος, translit=Ípiros, ) is a traditional geographic and modern administrative region in northwestern Greece.Π.Δ. 51/87 “Καθορισμός των Περιφερειών της Χώρας για το σχεδιασμό κ.λ.π. της Περιφερειακής Ανάπτυξης” (''Determination of the Regions of the Country for the planning etc. of the development of the regions, Efimeris tis Kyverniseos ΦΕΚ A 26/06.03.1987'' It borders the regions of Western Macedonia and Thessaly to the east, West Greece to the south, the Ionian Sea and Ionian Islands to the west and Albania to the north. The region has an area of about . It is part of the wider historical region of Epirus, which overlaps modern Albania and Greece but lies mostly within Greek territory. Geography and ecology Greek Epirus, like the region as a whole, is rugged and mountainous. It comprises the land of the ancient Molossians and Thesprotians and a small part of the la ...

Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Kyra Frosini
Euphrosyne Vasileiou ( el, Ευφροσύνη Βασιλείου; 1773 – 11 January 1800), better known as Kyra Frosini (Κυρά Φροσύνη, "Lady Phrosyne"), was a Greek socialite who was executed for adultery in Ioannina by the Ottoman governor Ali Pasha of Ioannina along with 17 other women. In legend, she was allegedly executed for political reasons and was thereby viewed as a national heroine. The case of Kyra Frosini has been portrayed in fiction as a novel, an opera, a film as well as in folk songs. Life Kyra (Evfrosini) Frosini was the niece of the Bishop of Ioannina and married to the wealthy merchant Dimitrios Vasileiou, with whom she had two children. She was a leading member of the local aristocracy in Ioannina and known for her beauty and intelligence. Ali Pasha had carved out his own semi-autonomous state within the Ottoman Empire centered in Ioannina. In his court he brought in intellectuals from all over Europe. Evfrosini was the central figure and lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algal Bloom
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other organ ...

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 deriv ...

Ali Pasha Of Ioannina
Ali Pasha of Ioannina (1740 – 24 January 1822), was an Albanian ruler who served as pasha of a large part of western Rumelia, the Ottoman Empire's European territories, which was referred to as the Pashalik of Yanina. His court was in Ioannina, and the territory he governed incorporated central and southern Albania, most of Epirus and the western parts of Thessaly and Greek Macedonia. Ali had three sons: Muhtar Pasha, who served in the 1809 war against the Russians, Veli Pasha, who became Pasha of the Morea Eyalet and Salih Pasha, governor of Vlorë. Ali first appears in historical accounts as the leader of a band of brigands who became involved in many confrontations with Ottoman state officials in Albania and Epirus. He joined the administrative-military apparatus of the Ottoman Empire, holding various posts until 1788 when he was appointed pasha, ruler of the sanjak of Ioannina. His diplomatic and administrative skills, his interest in modernist ideas and concepts, his pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thyamis
The Thyamis ( el, Θύαμις), also known as Glykys (Γλυκύς) or Kalamas (Καλαμάς), is a river in the Epirus region of Greece. It flows into the Ionian Sea. It is long, and its drainage area is about , over 99% of which on Greek territory. The names of the Chameria region (''Tsamouria'' in Greek), as well as the Chams, derive from the river's name. Thyamis in ancient Greece was mentioned by Pausanias as forming the boundary between Thesprotis and Kestrine. In addition, Suda and Ptolemaeus mentioned it. Some Renaissance scholars believed that the English River Thames owed its name to the River Thyamis, as early Celtic tribes were thought to have migrated from the Epirus region to England. While this belief influenced the modern spelling of the English river's name, it is no longer regarded as credible. Geography The source of the river is near the village Kalpaki, in the northwestern part of the Ioannina regional unit. It flows south at first, and turns southwes ...
