International Tundra Experiment
The International Tundra Experiment (ITEX) is a long-term international collaboration of researchers examining the responses of arctic and alpine plants and ecosystems to climate change. Researchers measure plant responses to standardized, small-scale passive warming, snow manipulations, and nutrient additions. Researchers use small open-top chambers (OTCs) to passively increase mean air temperature by 1-2 °C. The ITEX approach has been validated by tundra responses at the plot level. The network has published meta-analyses on plant phenology, growth, and reproduction, composition and abundance, and carbon flux. The ITEX network consists of more than 50 sites in polar and alpine locations around the world.

Arctic Vegetation
About 1,702 species of plants live on the Arctic tundra, including flowering plants, short shrubs, herbs, grasses, mosses. These plants are adapted to short, cold growing seasons. They have the ability to withstand extremely cold temperatures in the winter (winter hardiness), and grow and reproduce in summer conditions that are quite limiting. As of 2005, arctic vegetation covered approximately of land. The area of arctic vegetation decreased by approximately from 1980 to 2000, with a corresponding increase in the boreal forest. This decrease is linked to the warming of the Arctic due to climate change. Adaptations Arctic plants have a number of adaptations to the compressed growing season and low temperatures: * They initiate growth rapidly in the spring, and flower and set seed much sooner than plants that grow in warmer conditions. * Their peak metabolic rate occurs at a much lower temperature than plants from farther south, but only peaks for a short growing season. * ...

Luzula
''Luzula'' is a genus of flowering plants in the rush family Juncaceae. The genus has a cosmopolitan distribution, with species occurring throughout the world, especially in temperate regions, the Arctic, and higher elevation areas in the tropics. Plants of the genus are known commonly as wood-rush, wood rush, or woodrush.''Luzula''. Integrated Taxonomic Information System (ITIS). Possible origins of the genus name include the Italian ''lucciola'' ("to shine, sparkle") or the ''luzulae'' or ''luxulae'', from ''lux'' ("light"), inspired by the way the plants sparkle when wet with [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foscagno Pass
Foscagno Pass ( it, Passo di Foscagno, rm, Pass da Fus-chagn) (el. 2291 m.) is a high mountain pass in the Alps in the province of Sondrio, northern Italy. The road (SS 301) connects Bormio in the east and Livigno in the west. It is the only link between Livigno and the rest of Italy, and is usually open all year round. This route also includes the subsidiary Eira Pass ( it, Passo d'Eira) (2209 m) which lies between the Foscagno Pass and Livigno itself. Here lies the village of Trepalle, part of Livigno municipality, and one of Europe's highest inhabited parishes. Although both sides of the pass are in the same country, Italy, you are required to pass through customs at the top. This is due to the duty-free status of Livigno. The pass is located on the main alpine watershed Watershed is a hydrological term, which has been adopted in other fields in a more or less figurative sense.

Gavia Pass
Gavia Pass ( it, Passo di Gavia) (el. 2621 m.) is a high mountain pass in the Italian Alps. It is the List of highest paved roads in the Alps, tenth highest paved road in the Alps. The pass lies in the Lombardy region and divides the province of Sondrio to the north and the province of Brescia to the south. The road over the pass (SS 300) connects Bormio to the northwest with Ponte di Legno to the south and is single track most on its southern section. Climbing around Gavia Pass There are many peaks to climb around. Directly above the pass on its east side is Corno dei Tre Signori (3360 m) and next to it Monte Gaviola (3025). On the other side of the road raises Monte Gavia (3223 m).

Herschel Island
Herschel Island (french: Île d'Herschel; Inuit languages: ''Qikiqtaruk'') is an island in the Beaufort Sea (part of the Arctic Ocean), which lies off the coast of Yukon in Canada, of which it is administratively a part. It is Yukon's only offshore island.

These people are the ancestors of the present-day Inuvialuit. The Inuvialuktun word for Herschel Island is "Qikiqtaruk", which simply means "island". The first European to sight the island was explorer Sir John Franklin, who named it on 15 July 1826.Burn, C. R. (2009) "After whom is Herschel Island named"? Arctic 62(3):317–323. It is not clear after whom the island was named.

''Oxyria digyna'' (mountain sorrel, wood sorrel, Alpine sorrel or Alpine mountain-sorrel) is a species of flowering plant in the buckwheat family (Polygonaceae).Sierra Nevada Wildflowers, Karen Wiese, 2nd ed., 2013, p. 108 It is native to arctic regions and mountainous parts of the Northern Hemisphere. Description Mountain sorrel is a perennial plant with a tough taproot; the plant grows to a height of . It grows in dense tufts, with stems that are usually unbranched and hairless. Both flowering stems and leaf stalks are somewhat reddish. The leaves are kidney-shaped, somewhat fleshy, on stalks from the basal part of the stem. Flowers are small, green and later reddish, and are grouped in an open upright cluster. The fruit is a small nut, encircled by a broad wing which finally turns red. Forming dense, red tufts, the plant is easily recognized. ''Oxyria digyna'' grows in wet places protected by snow in winter. ''Oxyria'' (from Greek) means "sour". Distribution and habitat Mounta ...
