  2. Arctic ecology - Wikipedia

    en.wikipedia.org/wiki/Arctic_ecology

    Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]

  3. Effects of climate change on biomes - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    [2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]

  4. Tundra - Wikipedia

    en.wikipedia.org/wiki/Tundra

    Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...

    Environmentalist Bill McKibben imagines what would happen if we "solved" climate change by 2050. Here's what the world would look like.

  6. Tundra of North America - Wikipedia

    These complex interactions between plants, animals and abiotic factors in the tundra are held together by the permafrost layer, located 450 metres (1,480 ft) under the soil. [3] However climate change is causing this crucial layer of frozen soil to melt. As a result, tundra communities are becoming unstable and basic processes are breaking down.

  7. International Tundra Experiment - Wikipedia

    en.wikipedia.org/wiki/International_Tundra...

    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. [1] Researchers measure plant responses to standardized, small-scale passive warming, snow manipulations, and nutrient additions.

  8. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    An environmental gradient, or climate gradient, is a change in abiotic (non-living) factors through space (or time). Environmental gradients can be related to factors such as altitude, depth, temperature, soil humidity and precipitation.

  9. Kalaallit Nunaat Arctic Steppe - Wikipedia

    en.wikipedia.org/wiki/Kalaallit_Nunaat_Arctic_Steppe

    On the west coast, the relatively warmer climate supports a dwarf-scrub heath and steppe-like vegetation. The warmest and driest areas, at the head of fjords, there are sheltered areas that support scrub and low forests of green alder ( Alnus alnobetula ), white birch ( Betula pubescens ), and Greenland mountain ash ( Sorbus groenlandica ).
