Sandy Blind Mole-rat
The sandy blind mole-rat (''Spalax arenarius'') is an endangered species of rodent in the family Spalacidae. It is endemic to Ukraine. It was first identified by Evdokia Reshetnik in 1939. Distribution and habitat It is restricted to a very small region of southern Ukraine, on sandy habitats along the lower Dnieper River on the Black Sea coastal plain. It inhabits moderately wet, sandy soils with low subterranean waters, in steppes dominated by absinth-grass or absinth-spurge, with sparse vegetation otherwise. It does not inhabit dry feathergrass steppe or moving sands. Status Only about 15,000 to 20,000 mature individuals are thought to exist. The primary segment of the population inhabits the Black Sea Biosphere Reserve, and is thought to have a stable population trend. However, populations outside of this protected area are thought to be declining. The primary threat to this species is habitat conversion by the afforestation Afforestation is the establishment of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipa
''Stipa'' is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the terminology of some prairie types. ...

Endemic Fauna Of Ukraine
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodents Of Europe
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose inciso ...

Spalax
''Spalax'' is a genus of rodent in the family Spalacidae, subfamily ''Spalacinae'' (blind mole-rats). It is one of two extant genera in the subfamily Spalacinae, alongside ''Nannospalax''.'''' Species in this genus are found in eastern Europe and western & central Asia. They are completely blind and have a subterranean lifestyle. Taxonomy Prior to 2013, ''Spalax'' was widely considered the only member of Spalacinae, with all blind mole-rat species being grouped within it. However, phylogenetic and morphological evidence supported some of the species within it forming a distinct lineage that diverged from the others during the Late Miocene, when a marine barrier formed between Anatolia and the Balkans. These species were reclassified into the genus ''Nannospalax'', making ''Spalax'' one of two extant spalacine genera.''''

Afforestation
Afforestation is the establishment of a forest or stand of trees (forestation) in an area where there was no previous tree cover. Many government and non-governmental organizations directly engage in afforestation programs to create forests and increase carbon capture. Afforestation is an increasingly sought-after method to fight climate concerns, as it is known to increase the soil quality and organic carbon levels into the soil, avoiding desertification. Afforestation is mainly done for conservational and commercial purposes. # The rate of net forest loss decreased substantially over the period 1990–2020 due to a reduction in deforestation in some countries, plus increases in forest area in others through afforestation and the natural expansion of forests. A 2019 study of the global potential for tree restoration showed that there is space for at least 9 million km2 of new forests worldwide, which is a 25% increase from current conditions. This forested area could store up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Sea Biosphere Reserve
The Black Sea Biosphere Reserve ( uk, Чорноморський біосферний заповідник) is a biosphere reserve of Ukraine that is located at littoral zone of the northern Black Sea coast covering regions of the Kherson and Mykolaiv Oblasts and including Gulf of Tendra and Yahorlyk Bay. The reserve is part of the National Academy of Sciences of Ukraine. History The preserve was initially established on July 14, 1927, as part of the Trans-Maritime Preserve by the decree No. 172 of the Council of People's Commissars of Ukrainian SSR. In 1933 the preserve became an independent research institution. In 1973 to the Black Sea Preserve were added the Danube floodplains, Kinski islands in Yahorlyk Bay, and the shallow portion of the Gulf of Tendra. Next year the neighboring Yahorlyk reserve was annexed as well. In 1981 the Danube floodplains became an independent preserve. In 1983 there was established the Black Sea Biosphere Reserve that included the Black Sea State ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pontic–Caspian Steppe
The Pontic–Caspian steppe, formed by the Caspian steppe and the Pontic steppe, is the steppeland stretching from the northern shores of the Black Sea (the Pontus Euxinus of antiquity) to the northern area around the Caspian Sea. It extends from Dobruja in the northeastern corner of Bulgaria and southeastern Romania, through Moldova and southern and eastern Ukraine, across the Russian Northern Caucasus, the Southern and lower Volga regions to western Kazakhstan, adjacent to the Kazakh steppe to the east, both forming part of the larger Eurasian Steppe. It forms a part of the Palearctic realm and of the temperate grasslands, savannas, and shrublands biome. The area corresponds to Cimmeria, Scythia, and Sarmatia of classical antiquity. Across several millennia, numerous tribes of nomadic horsemen used the steppe; many of them went on to conquer lands in the settled regions of Europe, Western Asia, and Southern Asia. The term Ponto-Caspian region is used in biogeography ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Dnieper
} The Dnieper () or Dnipro (); , ; . is one of the major transboundary rivers of Europe, rising in the Valdai Hills near Smolensk, Russia, before flowing through Belarus and Ukraine to the Black Sea. It is the longest river of Ukraine and Belarus and the fourth-longest river in Europe, after the Volga, Danube, and Ural rivers. It is approximately long, with a drainage basin of . In antiquity, the river was part of the Amber Road trade routes. During the Ruin in the later 17th century, the area was contested between the Polish–Lithuanian Commonwealth and Russia, dividing Ukraine into areas described by its right and left banks. During the Soviet period, the river became noted for its major hydroelectric dams and large reservoirs. The 1986 Chernobyl disaster occurred on the Pripyat, immediately above that tributary's confluence with the Dnieper. The Dnieper is an important navigable waterway for the economy of Ukraine and is connected by the Dnieper–Bug Canal to other ...
