Alpine climate in the context of "Sympagic ecology"

Kosovo, officially the Republic of Kosovo, is a landlocked country in Southeast Europe with partial diplomatic recognition. It is bordered by Albania to the southwest, Montenegro to the west, Serbia to the north and east, and North Macedonia to the southeast. It covers an area of 10,887 km (4,203 sq mi) and has a population of nearly 1.6 million, of whom the vast majority (approximately 92 per cent) are ethnic Albanians. Kosovo has a varied terrain, with high plains along with rolling hills and mountains, some of which have an altitude over 2,500 m (8,200 ft). Its climate is mainly continental with some Mediterranean and Alpine influences. Kosovo's capital and most populous city is Pristina; other major cities and urban areas include Prizren, Ferizaj, Gjilan, and Peja.

Kosovo formed the core territory of the Dardani, an Illyrian people, attested in classical sources from the 4th century BCE. The Dardani established the Kingdom of Dardania, with its political and cultural center likely located near present-day Lipjan (ancient Ulpiana). The kingdom was incorporated into the Roman Empire in the 1st century BCE; later, in the 3rd century CE, it was transformed into a separate Roman province. During the Byzantine period, the region was eventually organised as part of the Theme of Dardania and remained under imperial control, facing Slavic migrations in the 6th and 7th centuries CE. Control shifted between the Byzantines and the First Bulgarian Empire. In the 13th century, Kosovo became integral to the Serbian medieval state and the establishment of the Serbian Patriarchate. Ottoman expansion in the Balkans in the late 14th and 15th centuries led to the decline and fall of the Serbian Empire; the Battle of Kosovo of 1389, in which a Serbian-led coalition of various ethnicities fought against the Ottoman Empire, is considered one of the defining moments.

Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply.

In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions.

Succulents may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as Glottiphyllum semicyllindricum and Mesembryanthemum barkleyii. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs (caudex) may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky or sandy soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to survive in ecosystems that contain scarce water sources.

Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level and merges with polar tundra.

The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as krummholz. With increasing elevation it ends at the snow line where snow and ice persist through summer.

New Mexico is a landlocked state in the Southwestern region of the United States. It is one of the Mountain States of the southern Rocky Mountains, sharing the Four Corners region with Utah, Colorado, and Arizona. It also borders the state of Texas to the east and southeast, Oklahoma to the northeast, and shares an international border with the Mexican states of Chihuahua and Sonora to the south. New Mexico's largest city is Albuquerque, and its state capital is Santa Fe, the oldest state capital in the U.S.—founded in 1610 as the government seat of Nuevo México in New Spain—and the highest in elevation, at 6,998 feet (2,133 m).

New Mexico is the fifth-largest of the fifty states by area, but with just over 2.1 million residents, ranks 36th in population and 45th in population density. Its climate and geography are highly varied, ranging from forested mountains to sparse deserts; the northern and eastern regions exhibit a colder alpine climate, while the west and south are warmer and more arid. The Rio Grande and its fertile valley runs from north-to-south, creating a riparian biome through the center of the state that supports a bosque habitat and distinct Albuquerque Basin climate. One–third of New Mexico's land is federally owned, including many protected wilderness areas, 15 national parks and monuments, and three UNESCO World Heritage Sites wholly contained within the state—the most of any U.S. state.

The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification. It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F). If the climate occurs at high elevations, it is known as alpine climate.

Despite the potential diversity of climates in the ET category involving precipitation, extreme temperatures, and relative wet and dry seasons, this category is rarely subdivided. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes. The amount of native tundra biomass depends more on the local temperature than the amount of precipitation.

Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes, such as frost shattering, frost wedging, and cryofracturing. The process may act on a wide range of spatial and temporal scales, from minutes to years and from dislodging mineral grains to fracturing boulders. It is most pronounced in high-altitude and high-latitude areas and is especially associated with alpine, periglacial, subpolar maritime, and polar climates, but may occur anywhere at sub-freezing temperatures (between −3 and −8 °C (27 and 18 °F)) if water is present.

Sikkim (/ˈsɪkɪm/ SIK-im; Nepali: [ˈsikːim]) is a state in northeastern India. It borders Bhutan in the east, the Tibet Autonomous Region of China in the north and northeast, Koshi Province of Nepal in the west, and West Bengal in the south. Sikkim is also close to the Siliguri Corridor, which borders Bangladesh. Sikkim is the least populous and second-smallest among the Indian states. Situated in the Eastern Himalaya, Sikkim is notable for its biodiversity, including alpine and subtropical climates, as well as being a host to Kangchenjunga, the highest peak in India and third-highest on Earth. Sikkim's capital and largest city is Gangtok. Almost 35% of the state is covered by Khangchendzonga National Park – a UNESCO World Heritage Site.

The Kingdom of Sikkim was founded by the Namgyal dynasty in the 17th century. It was ruled by Buddhist priest-kings known as the Chogyal. It became a princely state of the British Indian Empire in 1890. Following Indian independence, Sikkim continued its protectorate status with the Union of India after 1947 and the Republic of India after 1950. It enjoyed the highest literacy rate and per capita income among Himalayan states. In 1973, anti-royalist riots took place in front of the Chogyal's palace. In 1975, after the Indian Army took over the city of Gangtok, a referendum was held that led to the dissolution of the monarchy and Sikkim's joining India as its 22nd state.
