Veselina (river)
The Veselina () is a 70 km-long river in northern Bulgaria, a left tributary of the Stara reka (Yantra), Stara reka, itself a right tributary of the river Yantra (river), Yantra of the Danube basin. It is the second largest tributary of the Stara reka, after the Golyama reka. Geography The Veselina takes its source at an altitude of 784 m southwest of the village of Drenta in the Elena–Tvarditsa division of the Balkan Mountains. It heads northeast until the village of Dobrevtsi, Veliko Tarnovo Province, Dobrevtsi and then flows north in a deep forested valley until reaching the Yovkovtsi, Yovkovtsi Reservoir. After flowing out of the reservoir close to the Kapinovо Monastery the river cuts through the Elena Heights in a picturesque 4 km gorge. Downstream of the monastery it turns northeast and the valley widens, supporting farmlands. After the confluence with its tributary the Bebrovska reka, the Veselina turns north and flows into the Stara reka at an altitude ...

Balkan Mountains
The Balkan mountain range is located in the eastern part of the Balkan peninsula in Southeast Europe, Southeastern Europe. It is conventionally taken to begin at the peak of Vrashka Chuka on the border between Bulgaria and Serbia. It then runs for about , first in a south-easterly direction along the border, then eastward across Bulgaria, forming a natural barrier between the northern and southern halves of the country, before finally reaching the Black Sea at Cape Emine. The mountains reach their highest point with Botev Peak at . In much of the central and eastern sections, the summit forms the watershed between the drainage basins of the Black Sea and the Aegean Sea, Aegean. A prominent gap in the mountains is formed by the predominantly narrow Iskar Gorge, a few miles north of the Bulgarian capital, Sofia. The karst relief determines the large number of caves, including Magura Cave, Magura, featuring the most important and extended European post-Palaeolithic cave painting, Le ...

Zlatarishka Reka
The Zlatarishka reka () is a 56.5 km-long river in northern Bulgaria, a right tributary of the Veselina, itself a right tributary of the river Stara reka of the Yantra. It is the largest tributary of the Veselina. The Zlatarishka reka takes its source under the name Zelenishka reka at an altitude of 1,315 m some 300 m north of the Chumerna refuge in the Elena–Tvarditsa division of the Balkan Mountains and flows in general direction north throughout its whole course. Until the village of Ruhovtsi it flows in a deep forested valley, which eventually widens as it runs through the eastern parts of the Elena Valley. It then bisects the Elena Heights in the 10 km long Boaza Gorge. Downstream of the gorge the valley widens again, the river passes through Zlataritsa and some 1.6 km north of the town flows into the Veselina at an altitude of 85 m. Its drainage basin covers a territory of 187 km2 or 21.2% of the Veselina's total. High water is in March ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Tree Frog
The European tree frog (''Hyla arborea'') is a small tree frog. As traditionally defined, it was found throughout much of Europe, Asia and northern Africa, but based on molecular genetic and other data several populations formerly included in it are now recognized as separate species (for example, '' H. intermedia'' of Italy and nearby, '' H. molleri'' of the Iberian Peninsula, '' H. meridionalis'' of parts of southwestern Europe and northern Africa, and '' H. orientalis'' of parts of Eastern Europe, Turkey and the Black Sea and Caspian Sea regions), limiting the true European tree frog to Europe from France to Poland and Greece. Description European tree frogs are small; males range from in length, and females range from in length. They are slender, with long legs. Their dorsal skin is smooth, while their ventral skin is granular. Their dorsal skin can be green, gray, or tan depending on the temperature, humidity, or their mood. Their ventral skin is a whitish color, and the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Salamander
The fire salamander (''Salamandra salamandra'') is a common species of salamander found in Europe. It is black with yellow spots or stripes to a varying degree; some specimens can be nearly completely black while on others the yellow is dominant. Shades of red and orange may sometimes appear, either replacing or mixing with the yellow according to subspecies. This bright coloration is highly conspicuous and acts to deter predators by signalling theory#Honest signals, honest signalling of its toxicity (aposematism). Fire salamanders can have a very long lifespan; one specimen lived for more than 50 years in Museum Koenig, a German natural history museum. Despite its wide distribution and abundance, it is classified as Vulnerable species, Vulnerable on the IUCN Red List due to its susceptibility to infection by the introduced fungus ''Batrachochytrium salamandrivorans'', which has caused severe declines in fire salamanders in parts of its range. Taxonomy Several subspecies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-bellied Toad
The yellow-bellied toad (''Bombina variegata'') belongs to the order Anura, the family Bombinatoridae, and the genus of fire-bellied toads. The toad is distributed mainly across western Europe as well as a handful of countries in eastern Europe. While the population of the toad is steadily decreasing over time, its numbers are not critical enough to be considered threatened or extinct. Conservation efforts in Germany are taking place to remedy the declining population before it is too late. The toad is characterized by its bright ‘yellow belly,’ and has a dark brown and green dorsal body. The toad displays crypsis to camouflage itself from predators. It also positions itself to display yellow coloration when facing a threat. The warts found on the dorsal side allow for the toad's toxins to be readily excreted when needed. The yellow-bellied toad is a fascinating species to study because of its breeding choices; it chooses calculated risk when deciding to breed in shallo ...

Smooth Newt
The smooth newt, European newt, northern smooth newt or common newt (''Lissotriton vulgaris'') is a species of newt. It is widespread in Europe and parts of Asia, and has been introduced species, introduced into Australia. Individuals are brown with a spotted underside that ranges in colour from orange to white. They reach an average length of ; males are larger than females. The newts' skins are dry and velvety when they are living on land, but become smooth when they migration (ecology), migrate into the water to breed. Males develop a more vivid colour pattern and a conspicuous skin seam (crest) on their back when breeding. The smooth newt was originally described by Carl Linnaeus as a lizard, and was then given different genus (biology), genus names before the adoption of its current classification as a member of ''Lissotriton''. There are currently three accepted subspecies of smooth newt. Formerly, there were also four subspecies—all with more restricted ranges—that ar ...

Balkan Crested Newt
The Balkan crested newt or Buresch's crested newt (''Triturus ivanbureschi'') is a newt species of the crested newt species complex in genus '' Triturus'', found in Southeastern Europe and Anatolia. It was originally described as a subspecies of the southern crested newt, "''Triturus karelinii arntzeni''", in 1999, and later considered a full species when genetic data showed it to be distinct. After it was suggested the type specimen of "''T. arntzeni''" belonged in fact to the Macedonian crested newt (''T. macedonicus''), the species was redescribed, with a new type specimen, as ''T. ivanbureschi'' in 2013. The species epithet was chosen in honour of Bulgarian herpetologist Ivan Buresh. Its distribution ranges from the Southeastern Balkan peninsula (Western North Macedonia, Northwestern Greece, Bulgaria, Eastern Thrace) to Western Anatolia. An isolated population, surrounded by other crested newt species, occurs in Serbia. Genetic data showed that Northern Anatolian populati ...

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 ...

Populus
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar (Populus trichocarpa, ''P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The Bark (botany), bark on young trees is smooth and white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole (botany), petiole; in species in the sections ''Populus'' ...

Willow
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. Lea ...
