Palearctic realm in the context of "Rhodope mountains"

The Pontic–Caspian Steppe is a steppe extending across Eastern Europe to Central Asia, formed by the Caspian and Pontic steppes. It stretches from the northern shores of the Black Sea (the Pontus Euxinus of antiquity) to the northern area around the Caspian Sea, where it ends at the Ural-Caspian narrowing, which joins it with the Kazakh Steppe in Central Asia, making it a part of the larger Eurasian Steppe. Geopolitically, the Pontic–Caspian Steppe extends from northeastern Bulgaria and southeastern Romania through Moldova, southern and eastern Ukraine, through the North Caucasus of southern Russia, and into the Lower Volga region where it straddles the border of southern Russia and western Kazakhstan. Biogeographically, it is 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 Central and Eastern Europe, West Asia, and South Asia.

The Rhodopes (/ˈrɒdəpiːz/; Bulgarian: Родопи, Rodopi; Greek: Ροδόπη, Rodopi; Turkish: Rodoplar) are a mountain range in Southeastern Europe, and the largest by area in Bulgaria, with over 83% of its area in the southern part of the country and the remainder in Greece. Golyam Perelik is its highest peak at 2,191 meters (7,188 ft). The mountain range gives its name to the terrestrial ecoregion Rodope montane mixed forests that belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm. The region is particularly notable for its karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge.

A significant part of Bulgaria's hydropower resources are located in the western areas of the range. There are a number of hydro-cascades and dams used for electricity production, irrigation, and as tourist destinations.

Koritnik (Albanian definite form: Koritniku) is a wooded, limestone mountain, located in northeastern Albania and southwest Kosovo between the cities of Kukës and Prizren. The mountain is entirely surrounded by branches of the White Drin river. The highest point of Koritnik massif, Maja e Pikëllimës reaches an elevation of 2,393 metres (7,851 ft) above the Adriatic. Gryka e Vanavës (English: Vanave Gorge) separates the mountain from Gjallica. The gorge is 3.5 km (2.2 mi) long, 30 m (100 ft) wide, and about 300 m (980 ft) deep.

The massif falls within the Balkan mixed forests terrestrial ecoregion of the Palearctic temperate broadleaf and mixed forests biome. The slopes of the mountain meadows are mostly covered with coniferous forests. The high pastures of the Koritnik mountain help sustain a population of around 60 chamois.

Gjallica or Gjallica e Lumës is a limestone mountain at 2,487 m (8,159 ft) above sea level and the highest summit in the region of Kukës County, Albania. It lies 8 km (5 mi) southeast of the city of Kukës, having a cap covered by snow up to June when the winters are cold and snowy.

The mountain falls within the Balkan mixed forests and Dinaric Mountains mixed forests terrestrial ecoregions of the Palearctic Temperate broadleaf and mixed forests biome. The slopes of the mountain are entirely covered with coniferous forests. It has thick vegetation of pines and beeches on high altitude, but sparse vegetation on the foot of the mountain due to the now closed plant that emitted harmful gases for the vegetation close to it. Gjallica appears to be very tall because the Black Drin valley to its west is only 250 m (820 ft) above sea level.

Çikë, (Albanian pronunciation: [mali i tʃikəs]) at 2,044 metres (6,706 ft) above sea level, is the highest peak of the Ceraunian Mountains range in Albania which extends approximately 100 kilometres (62 mi) along the Albanian Riviera in a northwesterly direction from Sarandë to the Karaburun Peninsula. With a prominence of 1,563 metres (5,128 ft), Çikë is the 85th most prominent mountain peak in Europe.

The climate is Mediterranean, having hot summers and generally warm to cool, dry winters. The mount falls within the Illyrian deciduous forests terrestrial ecoregion of the Palearctic temperate broadleaf and mixed forests biome. The mount is also part of the Llogara National Park, which is noted for its rich biodiversity and vegetation. The western flank of the mount is vegetated by species such as the Bulgarian fir, Austrian pine, Bosnian pine and Macedonian pine.

The European Plain or the Great European Plain is a plain in Europe and is a major feature of one of four major topographical units of Europe – the Central and Interior Lowlands. It is the largest mountain-free landform in Europe, although a number of highlands are identified within it.

The stock dove (Columba oenas) is a species of bird in the family Columbidae, the doves and pigeons. It is widely distributed in the western Palearctic, north to central Scandinavia and south to northwest Africa. Western and southern populations are resident, while northeastern populations are migratory to avoid the colder winters there. It is the type species of the genus Columba.

The Kazakh Steppe (Kazakh: Қазақ даласы, romanized: Qazaq dalasy [qɑˈzɑq dɑɫɑˈsə]), also known as the Great Steppe or Great Dala (Kazakh: Ұлы дала, romanized: Ūly dala [ʊˈɫɤ dɑˈɫɑ]), is a vast region of open grassland in Central Asia, covering areas in northern Kazakhstan and adjacent areas of Russia. It lies east of the Pontic–Caspian steppe and west of the Emin Valley steppe, with which it forms the central and western part of the Eurasian steppe. The Kazakh Steppe is an ecoregion of the temperate grasslands, savannas, and shrublands biome in the Palearctic realm. Before the mid-19th century, it was called the Kirghiz steppe, 'Kirghiz' being an old Russian word for the Kazakhs.

The Rodope montane mixed forests is a terrestrial ecoregion of Europe defined by the WWF. It belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm.

The Balkan mixed forests are a terrestrial ecoregion of southeastern Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm.

The Dinaric Mountains mixed forests are a terrestrial ecoregion of the temperate broadleaf and mixed forests biome in Southeastern Europe, according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It also is in the Palearctic realm.

The Illyrian deciduous forests is a terrestrial ecoregion in southern Europe, which extends along the eastern coast of the Adriatic Sea. It belongs to the Mediterranean forests, woodlands, and scrub biome, and is in the Palearctic realm.

The Arabian Desert (Arabic: ٱلصَّحْرَاء ٱلْعَرَبِيَّة) is a vast desert wilderness in West Asia that occupies almost the entire Arabian Peninsula with an area of 2,330,000 square kilometers (900,000 sq mi). It stretches from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It is the fourth largest desert in the world and the largest in Asia. At its center is Ar-Rub' al-Khali (The Empty Quarter), one of the largest continuous bodies of sand in the world. It is an extension of the Sahara Desert.

Gazelles, oryx, sand cats, and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand. The climate is mostly dry (the major part receives around 100 mm (3.9 in) of rain per year, but some very rare places receive as little as 50 mm), and temperatures oscillate between very high heat and seasonal night time freezes. It is part of the deserts and xeric shrublands biome and lie in biogeographical realms of the Palearctic (northern part) and Afrotropical (southern part).

A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions.A biogeographic realm is also known as "ecozone", although that term may also refer to ecoregions.
