Miocene
–
The Miocene is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago. The Miocene was named by Sir Charles Lyell and its name comes from the Greek words μείων and καινός and means less recent because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch, the earth went from the Oligocene through the Miocene and into the Pliocene, with the climate slowly cooling towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event, the apes arose and diversified during the Miocene, becoming widespread in the Old World. By the end of this epoch, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path, as in the Oligocene before it, grasslands continued to expand and forests to dwindle in extent. In the Miocene seas, kelp forests made their first appearance, the plants and animals of the Miocene were fairly modern. The Miocene faunal stages from youngest to oldest are typically named according to the International Commission on Stratigraphy, Two subdivisions each form the lower, middle, continents continued to drift toward their present positions. Mountain building took place in western North America, Europe, both continental and marine Miocene deposits are common worldwide with marine outcrops common near modern shorelines. Well studied continental exposures occur in the North American Great Plains, India continued to collide with Asia, creating dramatic new mountain ranges. The Tethys Seaway continued to shrink and then disappeared as Africa collided with Eurasia in the Turkish–Arabian region between 19 and 12 Ma. The subsequent uplift of mountains in the western Mediterranean region and a fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea near the end of the Miocene. The global trend was towards increasing aridity caused primarily by global cooling reducing the ability of the atmosphere to absorb moisture, climates remained moderately warm, although the slow global cooling that eventually led to the Pleistocene glaciations continued. Although a long-term cooling trend was well underway, there is evidence of a period during the Miocene when the global climate rivalled that of the Oligocene. The Miocene warming began 21 million years ago and continued until 14 million years ago, by 8 million years ago, temperatures dropped sharply once again, and the Antarctic ice sheet was already approaching its present-day size and thickness. Greenland may have begun to have large glaciers as early as 7 to 8 million years ago, life during the Miocene Epoch was mostly supported by the two newly formed biomes, kelp forests and grasslands. This allows for more grazers, such as horses, rhinoceroses, ninety five percent of modern plants existed by the end of this epoch. The higher organic content and water retention of the deeper and richer grassland soils, with long term burial of carbon in sediments, produced a carbon and this, combined with higher surface albedo and lower evapotranspiration of grassland, contributed to a cooler, drier climate. The expansion of grasslands and radiations among terrestrial herbivores correlates to fluctuations in CO2

Yellow-bellied marmot
–
The yellow-bellied marmot, also known as the rock chuck, is a ground squirrel in the marmot genus. The fur is brown, with a dark bushy tail, yellow chest. They live in burrows in colonies of up to twenty individuals with a dominant male. They are diurnal and feed on plant material, insects and bird eggs and they hibernate for about eight months from September till the weather warms up. Yellow-bellied marmots usually weigh from 1.6 to 5.2 kilograms when fully grown, adult males typically weigh between 3 to 5 kilograms, females typically weigh between 1.6 to 4 kilograms. They have a coat, a white patch of fur between the eyes, a reddish-brown tail, and a yellow belly, from which they get their name. Their ears are small and round, and they have a white muzzle with a black nose. They get fatter in the autumn just before hibernating, the yellow-bellied marmot lives in the western United States and southwestern Canada, including the Rocky Mountains and the Sierra Nevada. It inhabits steppes, meadows, talus fields and other habitats, sometimes on the edge of deciduous or coniferous forests. Their territory is about 4 to 7 acres around a number of summer burrows, marmots choose to dig burrows under rocks because predators are less likely to see their burrow. Predators include wolves, foxes, coyotes, dogs and eagles, when a marmot sees a predator, it whistles to warn all other marmots in the area. Then it typically hides in a rock pile. Marmots reproduce when about two old, and may live up to an age of fifteen years. They reside in colonies of about ten to twenty individuals, each male marmot digs a burrow soon after he wakes up from hibernation. He then starts looking for females, and by summer may have up to four female mates living with him, litters usually average three to five offspring per female. Only about half of those pups survive and become yearlings, marmots have a harem-polygynous mating system in which the male reproduces with two or three mates at the same time. Female offspring tend to stay in the area around their home, male offspring typically leave when they are yearlings and will defend one or more females. Yellow-bellied marmots spend about 80% of their life in their burrow and they often spend mid-day and night in a burrow as well

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Animal
–
Animals are multicellular, eukaryotic organisms of the kingdom Animalia. The animal kingdom emerged as a clade within Apoikozoa as the group to the choanoflagellates. Animals are motile, meaning they can move spontaneously and independently at some point in their lives and their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs, they must ingest other organisms or their products for sustenance, most known animal phyla appeared in the fossil record as marine species during the Cambrian explosion, about 542 million years ago. Animals can be divided broadly into vertebrates and invertebrates, vertebrates have a backbone or spine, and amount to less than five percent of all described animal species. They include fish, amphibians, reptiles, birds and mammals, the remaining animals are the invertebrates, which lack a backbone. These include molluscs, arthropods, annelids, nematodes, flatworms, cnidarians, ctenophores, the study of animals is called zoology. The word animal comes from the Latin animalis, meaning having breath, the biological definition of the word refers to all members of the kingdom Animalia, encompassing creatures as diverse as sponges, jellyfish, insects, and humans. Aristotle divided the world between animals and plants, and this was followed by Carl Linnaeus, in the first hierarchical classification. In Linnaeuss original scheme, the animals were one of three kingdoms, divided into the classes of Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia. Since then the last four have all been subsumed into a single phylum, in 1874, Ernst Haeckel divided the animal kingdom into two subkingdoms, Metazoa and Protozoa. The protozoa were later moved to the kingdom Protista, leaving only the metazoa, thus Metazoa is now considered a synonym of Animalia. Animals have several characteristics that set apart from other living things. Animals are eukaryotic and multicellular, which separates them from bacteria and they are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls. All animals are motile, if only at life stages. In most animals, embryos pass through a stage, which is a characteristic exclusive to animals. With a few exceptions, most notably the sponges and Placozoa and these include muscles, which are able to contract and control locomotion, and nerve tissues, which send and process signals
5.
Chordate
–
Chordates are deuterostomes, as during the embryo development stage the anus forms before the mouth. They are also bilaterally symmetric coelomates, in the case of vertebrate chordates, the notochord is usually replaced by a vertebral column during development, and they may have body plans organized via segmentation. There are also additional extinct taxa, the Vertebrata are sometimes considered as a subgroup of the clade Craniata, consisting of chordates with a skull, the Craniata and Tunicata compose the clade Olfactores. Of the more than 65,000 living species of chordates, the worlds largest and fastest animals, the blue whale and peregrine falcon respectively, are chordates, as are humans. Fossil chordates are known from at least as early as the Cambrian explosion, Hemichordata, which includes the acorn worms, has been presented as a fourth chordate subphylum, but it now is usually treated as a separate phylum. The Hemichordata, along with the Echinodermata, form the Ambulacraria, the Chordata and Ambulacraria form the superphylum Deuterostomia, composed of the deuterostomes. Attempts to work out the relationships of the chordates have produced several hypotheses. All of the earliest chordate fossils have found in the Early Cambrian Chengjiang fauna. Because the fossil record of early chordates is poor, only molecular phylogenetics offers a prospect of dating their emergence. However, the use of molecular phylogenetics for dating evolutionary transitions is controversial and it has also proved difficult to produce a detailed classification within the living chordates. Attempts to produce family trees shows that many of the traditional classes are paraphyletic. While this has been known since the 19th century, an insistence on only monophyletic taxa has resulted in vertebrate classification being in a state of flux. Although the name Chordata is attributed to William Bateson, it was already in prevalent use by 1880, ernst Haeckel described a taxon comprising tunicates, cephalochordates, and vertebrates in 1866. Though he used the German vernacular form, it is allowed under the ICZN code because of its subsequent latinization, among the vertebrate sub-group of chordates the notochord develops into the spine, and in wholly aquatic species this helps the animal to swim by flexing its tail. In fish and other vertebrates, this develops into the spinal cord, the pharynx is the part of the throat immediately behind the mouth. In fish, the slits are modified to form gills, a muscular tail that extends backwards behind the anus. This is a groove in the wall of the pharynx. In filter-feeding species it produces mucus to gather food particles, which helps in transporting food to the esophagus and it also stores iodine, and may be a precursor of the vertebrate thyroid gland

Mammal
–
Mammals are any vertebrates within the class Mammalia, a clade of endothermic amniotes distinguished from reptiles by the possession of a neocortex, hair, three middle ear bones and mammary glands. All female mammals nurse their young with milk, secreted from the mammary glands, Mammals include the largest animals on the planet, the great whales. The basic body type is a quadruped, but some mammals are adapted for life at sea, in the air, in trees. The largest group of mammals, the placentals, have a placenta, Mammals range in size from the 30–40 mm bumblebee bat to the 30-meter blue whale. With the exception of the five species of monotreme, all modern mammals give birth to live young, most mammals, including the six most species-rich orders, belong to the placental group. The largest orders are the rodents, bats and Soricomorpha, the next three biggest orders, depending on the biological classification scheme used, are the Primates, the Cetartiodactyla, and the Carnivora. Living mammals are divided into the Yinotheria and Theriiformes There are around 5450 species of mammal, in some classifications, extant mammals are divided into two subclasses, the Prototheria, that is, the order Monotremata, and the Theria, or the infraclasses Metatheria and Eutheria. The marsupials constitute the group of the Metatheria, and include all living metatherians as well as many extinct ones. Much of the changes reflect the advances of cladistic analysis and molecular genetics, findings from molecular genetics, for example, have prompted adopting new groups, such as the Afrotheria, and abandoning traditional groups, such as the Insectivora. The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade, the early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the line that led to todays reptiles. Some mammals are intelligent, with some possessing large brains, self-awareness, Mammals can communicate and vocalize in several different ways, including the production of ultrasound, scent-marking, alarm signals, singing, and echolocation. Mammals can organize themselves into fission-fusion societies, harems, and hierarchies, most mammals are polygynous, but some can be monogamous or polyandrous. They provided, and continue to provide, power for transport and agriculture, as well as commodities such as meat, dairy products, wool. Mammals are hunted or raced for sport, and are used as model organisms in science, Mammals have been depicted in art since Palaeolithic times, and appear in literature, film, mythology, and religion. Defaunation of mammals is primarily driven by anthropogenic factors, such as poaching and habitat destruction, Mammal classification has been through several iterations since Carl Linnaeus initially defined the class. No classification system is accepted, McKenna & Bell and Wilson & Reader provide useful recent compendiums. Though field work gradually made Simpsons classification outdated, it remains the closest thing to a classification of mammals

Rodent
–
Rodents 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 species are rodents, they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, Species can be arboreal, fossorial, or semiaquatic. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, hamsters, and capybaras. Other animals such as rabbits, hares, and pikas, whose incisors also grow continually, were included with them, but are now considered to be in a separate order. Nonetheless, Rodentia and Lagomorpha are sister groups, sharing a most recent common ancestor, most rodents are small animals with robust bodies, short limbs, and long tails. They use their incisors to gnaw food, excavate burrows. Most eat seeds or other plant material, but some have more varied diets and they tend to be social animals and many species live in societies with complex ways of communicating with each other. Mating among rodents can vary from monogamy, to polygyny, to promiscuity, many have litters of underdeveloped, altricial young, while others are precocial at birth. The rodent fossil record back to the Paleocene on the supercontinent of Laurasia. Rodents greatly diversified in the Eocene, as spread across continents. Rodents reached both South America and Madagascar from Africa, and were the only placental mammals to reach. Rodents have been used as food, for clothing, as pets, some species, in particular the brown rat, the black rat, and the house mouse, are serious pests, eating and spoiling food stored by humans, and spreading diseases. The distinguishing feature of the rodents is their pairs of continuously growing and these incisors have thick layers of enamel on the front and little enamel on the back. Because they do not stop growing, the animal must continue to wear them down so that they do not reach and pierce the skull. As the incisors grind against each other, the softer dentine on the rear of the teeth wears away, most species have up to 22 teeth with no canines or anterior premolars. A gap, or diastema, occurs between the incisors and the teeth in most species. This allows rodents to suck in their cheeks or lips to shield their mouth and throat from wood shavings and other inedible material, chinchillas and guinea pigs have a high-fiber diet, their molars have no roots and grow continuously like their incisors

Squirrel
–
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels, chipmunks, marmots, flying squirrels, Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known date from the Eocene period and are most closely related to the mountain beaver. That word squirrel, first attested in 1327, comes from the Anglo-Norman esquirel which is from the Old French escurel and this Latin word was borrowed from the Ancient Greek word σκίουρος, skiouros, which means shadow-tailed, referring to the bushy appendage possessed by many of its members. The native Old English word for the squirrel, ācweorna, survived only into Middle English before being replaced, Squirrels typically have slender bodies with bushy tails and large eyes. In general, their fur is soft and silky, although much thicker in some species than others, the color of squirrels is highly variable between—and often even within—species. In general, the limbs are longer than the fore limbs. Their paws include a poorly developed thumb, and have soft pads on the undersides. Unlike most mammals, Tree squirrels can descend a tree head-first and they do so by rotating their ankles 180 degrees so the hind paws are backward-pointing and can grip the tree bark. Squirrels live in almost every habitat from tropical rainforest to desert, avoiding only the high polar regions. They are predominantly herbivorous, subsisting on seeds and nuts, but many will eat insects, as their large eyes indicate, in general squirrels have an excellent sense of vision, which is especially important for tree-dwelling species. They also have very versatile and sturdy claws for grasping and climbing, many also have a good sense of touch, with vibrissae on their heads and limbs. The teeth of sciurids follow the typical rodent pattern, with large gnawing incisors that grow throughout life, the typical dental formula for sciurids is 1.0.1.31.0.1.3. Many juvenile squirrels die in the first year of life, adult squirrels can have a lifespan of 5 to 10 years in the wild. Some can survive 10 to 20 years in captivity, Squirrels breed once or twice a year and give birth to a varying number of young after three to six weeks, depending on species. The young are naked, toothless, and blind. In most species of squirrel, only the female looks after the young, in general, ground-dwelling species are social animals, often living in well-developed colonies, but the tree-dwelling species are more solitary. Squirrels cannot digest cellulose, so they must rely on foods rich in protein, carbohydrates, during these times, squirrels rely heavily on the buds of trees
9.
Ground squirrel
–
The ground squirrels are members of the squirrel family of rodents which generally live on or in the ground, rather than trees. Together, they make up the tribe of squirrels, Marmotini, and the large and mainly ground squirrel subfamily Xerinae. Well-known members of this largely Holarctic group are the marmots, including the American groundhog, the chipmunks, the susliks, and the prairie dogs. They are highly variable in size and habitus, but most are able to rise up on their hind legs. They also tend to be far more gregarious than other squirrels, most Marmotini are rather short-tailed and large squirrels, and the alpine marmot is the largest living member of the Sciuridae, at 53–73 cm in length and weighing 5–8 kg. The chipmunks of the genus Tamias frequently spend time in trees, also closer to typical squirrels in other aspects, they are occasionally considered a tribe of their own. The ground squirrel is especially renowned for its tendency to rise up on its hind legs and it does this whenever it senses nearby danger, or when it must see over tall grasses. The squirrel then curls its paws flat against its chest and sends a call to warn other family members about the presence of predators. Palaeosciurus from Europe is the oldest known ground squirrel species, the oldest fossils are from the Early Oligocene, more than 30 million years ago, but the genus probably persisted at least until the mid-Miocene, some 15 mya. It is not clear where the Marmotini originated, the subtribes probably diverged in the early to mid-Oligocene, as primitive marmots and chipmunks are known from the Late Oligocene of North America. A ground squirrel lives in areas like pastures, golf courses, cemeteries. Ground squirrels are omnivorous, and will not only eat a diet rich in fungi, nuts, fruits, and seeds, but also insects, eggs.

Alps
–
The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc, Mont Blanc spans the French–Italian border, and at 4,810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres, the altitude and size of the range affects the climate in Europe, in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as live in the higher peaks to elevations of 3,400 m. Evidence of human habitation in the Alps goes back to the Palaeolithic era, a mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established, Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800 Napoleon crossed one of the passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, in World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war. The Alpine region has a cultural identity. The Winter Olympic Games have been hosted in the Swiss, French, at present, the region is home to 14 million people and has 120 million annual visitors. The English word Alps derives from the Latin Alpes, maurus Servius Honoratus, an ancient commentator of Virgil, says in his commentary that all high mountains are called Alpes by Celts. The term may be common to Italo-Celtic, because the Celtic languages have terms for high mountains derived from alp and this may be consistent with the theory that in Greek Alpes is a name of non-Indo-European origin. According to the Old English Dictionary, the Latin Alpes might possibly derive from a pre-Indo-European word *alb hill, Albania, a name not native to the region known as the country of Albania, has been used as a name for a number of mountainous areas across Europe. In Roman times, Albania was a name for the eastern Caucasus, in modern languages the term alp, alm, albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a mountain pasture where cows are taken to be grazed during the summer months and where hay barns can be found. The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km arc from east to west and is 200 km in width, the mean height of the mountain peaks is 2.5 km. The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, the range continues onward toward Vienna, Austria, and east to the Adriatic Sea and Slovenia. To the south it dips into northern Italy and to the north extends to the border of Bavaria in Germany

Apennine Mountains
–
The Apennines or Apennine Mountains are a mountain range consisting of parallel smaller chains extending c. 1,200 km along the length of peninsular Italy. In the northwest they join with the Ligurian Alps at Altare, in the southwest they end at Reggio di Calabria, the coastal city at the tip of the peninsula. The system forms an arc enclosing the east side of the Ligurian and Tyrrhenian Seas, the name originally applied to the north Apennines. However, historical linguists have never found a derivation with which they are universally comfortable, wilhelm Deecke said. its etymology is doubtful but some derive it from the Ligurian-Celtish Pen or Ben, which means mountain peak. The mountains lend their name to the Apennine peninsula, which forms the part of Italy. They are mostly verdant, although one side of the highest peak, Corno Grande is partially covered by Calderone glacier and it has been receding since 1794. The eastern slopes down to the Adriatic Sea are steep, while the western slopes form foothills on which most of peninsular Italys cities are located. The mountains tend to be named from the province or provinces in which they are located, for example, as the provincial borders have not always been stable, this practice has resulted in some confusion about exactly where the montane borders are. Often but not always a feature can be found that lends itself to being a border. The Apennines are divided into three sectors, northern, central, and southern, a number of long hiking trails wind through the Apennines. Of note is European walking route E1 coming from northern Europe and traversing the lengths of the northern, the Grand Italian Trail begins in Trieste and after winding through the Alpine arc traverses the entire Apennine system, Sicily and Sardinia. The northern Apennines consist of three sub-chains, the Ligurian, Tuscan-Emilian, and Umbrian Apennines, the Ligurian Apennines border the Ligurian Sea in the Gulf of Genoa, from about Savona below the upper Bormida River valley to about La Spezia below the upper Magra River valley. The range follows the Gulf of Genoa separating it from the upper Po Valley, the northwestern border follows the line of the Bormida River to Acqui Terme. There the river continues northeast to Alessandria in the Po Valley, the upper Bormida can be reached by a number of roads proceeding inland at a right angle to the coast southwest of Savona, the chief one being the Autostrada Torino-Savona. They ascend to the Bocchetta di Altare, sometimes called Colle di Cadibona,436 m, a bronze plaque fixed to a stone marks the top of the pass. In the vicinity are fragments of the old road and three ruins of former fortifications, at Carcare, the main roads connect with the upper Bormida valley before turning west. The Scrivia, the Trebbia and the Taro, tributaries of the Po River, the range contains dozens of peaks. Toward the southern end the Aveto Natural Regional Park includes Monte Penna, nearby is the highest point of Ligurian Apennines, Monte Maggiorasca at 1,780 m

Carpathian Mountains
–
The Carpathian Mountains or Carpathians are a mountain range system forming an arc roughly 1,500 km long across Central and Eastern Europe, making them the second-longest mountain range in Europe. The Carpathians and their foothills also have many thermal and mineral waters, the Carpathians consist of a chain of mountain ranges that stretch in an arc from the Czech Republic in the northwest through Slovakia, Poland, Hungary and Ukraine to Romania and Serbia. The highest range within the Carpathians is the Tatras, on the border of Slovakia and Poland, the second-highest range is the Southern Carpathians in Romania, where the highest peaks exceed 2,500 m. The divisions of the Carpathians are usually in three sections, Western Carpathians — Czech Republic, Poland, and Slovakia. Eastern Carpathians — southeastern Poland, eastern Slovakia, Ukraine, Romania, the term Outer Carpathians is frequently used to describe the northern rim of the Western and Eastern Carpathians. The most important cities in or near the Carpathians are, Bratislava and Košice in Slovakia, Kraków in Poland, Cluj-Napoca, Sibiu and Braşov in Romania, and Uzhhorod in Ukraine. In modern times, the range is called Karpaty in Czech, Polish, Slovak and Карпати in Ukrainian, Carpați in Romanian, Karpaten in German, Kárpátok in Hungarian and Karpati or Карпати in Serbian. Although the toponym was recorded already by Ptolemy in the 2nd century CE, for instance, Havasok was its medieval Hungarian name, Rus and Romanian chronicles referred to it as Hungarian Mountains. The archaic Polish word karpa meant rugged irregularities, underwater obstacles/rocks, the more common word skarpa means a sharp cliff or other vertical terrain. In late Roman documents, the Eastern Carpathian Mountains were referred to as Montes Sarmatici, the Western Carpathians were called Carpates, a name that is first recorded in Ptolemys Geographia. In the Scandinavian Hervarar saga, which relates ancient Germanic legends about battles between Goths and Huns, the name Karpates appears in the predictable Germanic form as Harvaða fjöllum, inter Alpes Huniae et Oceanum est Polonia by Gervase of Tilbury, has described in his Otia Imperialia in 1211. Thirteenth- to fifteenth-century Hungarian documents named the mountains Thorchal, Tarczal or less frequently Montes Nivium, the northwestern Carpathians begin in Slovakia and southern Poland. They surround Transcarpathia and Transylvania in a semicircle, sweeping towards the southeast. The total length of the Carpathians is over 1,500 km, the highest altitudes of the Carpathians occur where they are widest. The Carpathians cover an area of 190,000 km2 and, after the Alps, although commonly referred to as a mountain chain, the Carpathians do not actually form an uninterrupted chain of mountains. Rather, they consist of several orographically and geologically distinctive groups, the Carpathians at their highest altitude are only as high as the middle region of the Alps, with which they share a common appearance, climate, and flora. The Carpathians are separated from the Alps by the Danube, the two ranges meet at only one point, the Leitha Mountains at Bratislava. The river also separates them from the Balkan Mountains at Orşova in Romania, the valley of the March and Oder separates the Carpathians from the Silesian and Moravian chains, which belong to the middle wing of the great Central Mountain System of Europe
