Montane ecosystems in the context of "Climate change"

Shebenik National Park (Albanian: Parku Kombëtar i Shebenikut) is a national park in eastern Albania adjacent to the border with North Macedonia. It encompasses 34,507.9 hectares (345.079 km) and is specifically marked by a mountainous landscape supplied with glacial lakes, valleys, dense coniferous and deciduous forests and alpine meadows and pastures. Elevations in the park vary from 300 metres to over 2,200 metres above the Adriatic at the peak of Shebenik and Jabllanica, hence the name. It dwells a number of endangered species that are fast becoming rare in Southern Europe, including the brown bear, gray wolf and Balkan lynx. The abundance in wildlife can in part be explained by the variety of vegetation types and remote location.

The park offers some of the most rugged scenery in the eastern section of country that were carved into their present shapes by the glaciers of the last ice age. It is home to 14 glacial lakes, the highest situated between 1,500 and 1,900 metres elevation above the Adriatic. Small cirque glaciers are fairly common in the mountain ranges, situated in depressions on the side of many mountains. Two rivers flow and multiple smaller water sources flow through the park's area including the rivers of Qarrishte and Bushtrice, both of which are 22 km long. The park area is thought to contain one of the primary remaining ranges of the Balkan lynx, a subspecies of the Eurasian lynx.

Eastern South Asia is a subregion of South Asia. It includes the countries of Bangladesh, Bhutan, India (specifically East India and Northeast India), and Nepal. Geographically, it lies between the Eastern Himalayas and the Bay of Bengal. Two of the world's largest rivers, the Ganges and the Brahmaputra, flow into the sea through Eastern South Asia. The region includes the world's highest mountainous terrain and the world's largest delta, and has a climate ranging from alpine and subalpine to subtropical and tropical. Since Nepal, Bhutan, and northeast India are landlocked, the coastlines of Bangladesh and East India serve as the principal gateways to the region.

With more than 441 million inhabitants, Eastern South Asia is home to 6% of the world's population and 25% of South Asia's population. The Bangladesh, Bhutan, India, Nepal Initiative promotes economic integration in the region. The four countries are members of the South Asian Association for Regional Cooperation and the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation. Yunnan Province and the Tibet Autonomous Region of the People's Republic of China (PRC) and Myanmar are historically, economically, and culturally interdependent on Eastern South Asia. The Bangladesh–China–India–Myanmar Forum has established an economic corridor in the region.

Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered deciduous conifer. It is the sole living species of the genus Metasequoia, one of three genera in the subfamily Sequoioideae of the family Cupressaceae. It now survives in the wild only in wet lower slopes and montane river and stream valleys in the border region of Hubei and Hunan provinces and Chongqing municipality in south-central China, notably in Lichuan county in Hubei. Although the shortest of the redwoods, it can grow to 167 ft (51 m) in height.

In 1941, the genus Metasequoia was reported by paleobotanist Shigeru Miki [jp] as a widely distributed extinct genus based on fossils, before attracting considerable attention a few years later when small populations were found alive in central China. It is a well-known example of a living fossil species. Modern dawn redwood appears identical to its late Cretaceous ancestors. The tree faces considerable risks of extinction in its wild range due to deforestation; however, it has been planted extensively in arboreta worldwide, where it has proved a popular and fast-growing ornamental plant. If the species had not been discovered when it was, it might have become extinct before being investigated.

Elms are deciduous and semi-deciduous trees comprising the genus Ulmus in the family Ulmaceae. They are distributed over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, ranging southward in Western Asia to Iran, in Africa to Libya, and in Southeast Asia into Indonesia.

Elms are components of many kinds of natural forests. Moreover, during the 19th and early 20th centuries, many species and cultivars were also planted as ornamental street, garden, and park trees in Europe, North America, and parts of the Southern Hemisphere, notably Australasia. Some individual elms reached great size and age. However, in recent decades, most mature elms of European or North American origin have died from Dutch elm disease, caused by a microfungus dispersed by bark beetles. In response, disease-resistant cultivars have been developed, capable of restoring the elm to forestry and landscaping.

Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau and has extended to similarly isolated high-elevation forests. The isolation has significant implications for these natural habitats. Endemism, altitudinal migration, and relict populations are some of the natural phenomena to be found on sky islands.

The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other mountain ranges, resulting in a habitat island, such as a forest surrounded by desert.

The western lowland gorilla (Gorilla gorilla gorilla) is one of two Critically Endangered subspecies of the western gorilla (Gorilla gorilla) that lives in montane, primary and secondary forest and lowland swampland in central Africa in Angola (Cabinda Province), Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. It is the nominate subspecies of the western gorilla, and the smallest of the four gorilla subspecies.

The western lowland gorilla is the only subspecies kept in zoos with the exception of Amahoro, a female eastern lowland gorilla at Antwerp Zoo, and a few mountain gorillas kept captive in the Democratic Republic of the Congo.
