Alpine tundra in the context of "Montane ecosystems"

In physical geography, a tundra (/ˈtʌndrə, ˈtʊn-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic, Alpine, and Antarctic.

Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained greenhouse gases into the atmosphere, creating a feedback cycle that contributes to climate change.

Montane grasslands and shrublands are a biome defined by the World Wide Fund for Nature. The term montane in the name of the biome refers to high elevation, rather than the ecological term that denotes the region below the treeline. The biome includes high-elevation (montane and alpine) grasslands and shrublands around the world, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, and other similar subalpine habitats.Drier subtropical montane grasslands, savannas, and woodlands include the Ethiopian Highlands, the Zambezian montane grasslands and woodlands, and the montane habitats of southeastern Africa.

The páramos of the northern Andes are the most extensive examples of the habitat type. Although ecoregion biotas are most diverse in the Andes, these ecosystems are distinctive wherever they occur in the tropics. The heathlands and moorlands of East Africa (e.g., Mount Kilimanjaro, Mount Kenya, Rwenzori Mountains), Mount Kinabalu of Borneo, and the Central Range of New Guinea are all limited in extent, isolated, and support endemic plants and animals.The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity.

Llogara National Park (Albanian: Parku Kombëtar i Llogarasë/Llogorasë) is a national park centered on the Ceraunian Mountains along the Albanian Riviera in southwestern Albania, spanning a surface area of 1,769 ha (17.69 km). The park's terrain includes large alpine meadows, vertical rock faces, precipices and dense forests. Most area of the park is covered by forests and was established in 1966 to protect several ecosystems and biodiversity of national importance. The International Union for Conservation of Nature (IUCN) has listed the park as Category II. The region has been recognised as an important Bird and Plant Area, supporting significant number of species.

The park features outstanding diversity with the landscape ranging from the alpine peaks of the Ceraunian Mountains covered with snow in winter to the sunny Albanian Ionian Sea Coast in summer. At 1,027 m (3,369 ft), the Llogara Pass provides a striking scenery, with tall mountains overlooking the Albanian Riviera and several islands in the sea. The region experiences a mediterranean climate. This means that the summers are hot and the winters generally dry to warm to cool. Despite the vicinity to the mediterranean climatic region, an alpine climate prevails at the Maja e Çikës. Geomorphologically, carbonate rocks occupy most of the area, while the mountains are composed of limestones and dolomites.

Cladonia rangiferina, also known as reindeer cup lichen, reindeer lichen (cf. Sw. renlav) or grey reindeer lichen, is a light-coloured fruticose, cup lichen species in the family Cladoniaceae. It grows in both hot and cold climates in well-drained, open environments. Found primarily in areas of alpine tundra, it is extremely cold-hardy.

Other common names include reindeer moss, deer moss, and caribou moss, but these names can be misleading since it is, though somewhat moss-like in appearance, not a moss. As the common names suggest, reindeer lichen is an important food for reindeer (caribou), and has economic importance as a result. Synonyms include Cladina rangiferina and Lichen rangiferinus.

MultiCam is a camouflage pattern designed for use in a wide range of environments and conditions which was developed and is produced by American company Crye Precision. The pattern has found extensive adoption globally. Variants of it, some unlicensed, are in use with militaries worldwide, particularly with special forces/special operations forces units.

The pattern is also available for purchase for civilian usage. Derived from the original standard pattern, additional specified variants were developed and later introduced in late 2013, those are "Arid", "Tropic", "Alpine" and "Black".

Páramo (Spanish pronunciation: [ˈpaɾamo]) may refer to a variety of alpine tundra ecosystems located in the Andes Mountains in South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", meaning that they are among the fastest evolving regions on Earth.
