Sredetska Reka
The Sredetska reka () is a 69 km long river in southeastern Bulgaria, which flows into Lake Mandrensko, itself draining into the Black Sea. Geography The river springs in the northwestern foothills of Kamen Vrah (369 m) in the Bakadzhitsite heights. Some 2.5–3 km from the source, the river flows northeast through a vaguely defined valley with very oblique slopes, covered with oak forests. Downstream the river valley takes pronounced trapezoidal cross-section. The longitudinal slope of the bed is 2.2%, and it remains until the Chetmanska River flows into it. The banks of the riverbed are 0.6–0.7 m high and almost vertical. The bottom of the river is formed by gravels and sand. The Sredetska reka does not form meanders in its upper course. After the confluence with the Chetmanska reka, the river enters a 50–60 m wide hilly valley with shrubs along the rights banks. Downstream from the village of Aleksandrovo the slopes of its banks become steep and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. The Natura 2000 network covered more than 18% of the European Union's land area and more than 7% of its marine area in 2022. 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 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 o ...

Eurasian Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, European river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia and the Maghreb. The most widely distributed member of the otter subfamily (Lutrinae) of the Mustelidae, weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the ...

European Bitterling
The European bitterling (''Rhodeus amarus'') is a temperate freshwater ray-finned fish belonging to the family Acheilognathidae, the bitterlings. It originates in Europe, ranging from the Rhone River basin in France to the Neva River in Russia. It was originally described as ''Cyprinus amarus'' by Marcus Elieser Bloch in 1782, and has been referred to in scientific literature as ''Rhodeus sericeus amarus''. It is known simply as "the bitterling" in its native range, where it is the only species of its genus '' Rhodeus'', and sometimes in the scientific literature, also, but this is technically wrong, being a leftover from the times when the European bitterling was united with its Siberian relative, the Amur bitterling, in ''R. sericeus''. Properly, "bitterling" can refer to any species of ''Acheilognathus'' or ''Rhodeus''. The fish reaches a size of up to . It is found among plants over sandy and muddy bottoms in shallow waters. It feeds mainly on plants, and to a lesser extent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Barbus cyclolepis'', the round-scaled barbel, is a freshwater fish species in the family Cyprinidae. It is found in Bulgaria, Greece, and Turkey. Its natural habitats are rivers and intermittent rivers. It is not considered a threatened species by the IUCN. A broader concept of ''Barbus cyclolepis'' would include in the same species several other barbel taxa that others consider distinct species, i.e. ''Barbus sperchiensis ''Barbus sperchiensis'' is a disputed species of cyprinid fish in the genus ''Barbus ''Barbus'' is a genus of ray-finned fish in the family Cyprinidae.

Bulgarian Black Sea Coast
The Bulgarian Black Sea Coast (), also known as the Bulgarian Riviera, covers the entire eastern bound of Bulgaria stretching from the Romanian Black Sea resorts in the north to European Turkey in the south, along 378 km of coastline. White and golden sandy beaches occupy approximately 130 km of the 378 km long coast. The region is an important center of tourism during the summer season (May–October), drawing millions of foreign and local tourists alike and constituting one of the country's most popular tourist destinations. Prior to 1989 the Bulgarian Black Sea coast was internationally known as the ''Red Riviera''. Since the fall of the Iron Curtain, however, its nickname has been changed to the ''Bulgarian Riviera''. The Bulgarian Black Sea Coast has a humid subtropical climate (Köppen climate classification ''Cfa''), with considerable maritime and continental influences.

Barbus Bergi
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. The smaller barbs are in some cases traded as aquarium fish. Some are quite significant, but as a whole, the genus is not yet as well represented in aqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
