Arctic ecology (original) (raw)
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’). This region is characterized by stressful conditions as a result of extreme cold, low precipitation, a limited growing season (50–90 days) and virtually no sunlight throughout the winter. The Arctic consists of taiga (or boreal forest) and tundra biomes, which also dominate very high elevations, even in the tropics. Sensitive ecosystems exist throughout the Arctic region, which are being impacted dramatically by global warming.

| dbo:abstract | 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’). This region is characterized by stressful conditions as a result of extreme cold, low precipitation, a limited growing season (50–90 days) and virtually no sunlight throughout the winter. The Arctic consists of taiga (or boreal forest) and tundra biomes, which also dominate very high elevations, even in the tropics. Sensitive ecosystems exist throughout the Arctic region, which are being impacted dramatically by global warming. The earliest inhabitants of the Arctic were the Neanderthal sub-species. Since then, many indigenous populations have inhabited the region, which continues to this day. Since the early 1900s, when Vilhjalmur Stefansson led the first major Canadian Arctic Expedition, the Arctic has been a valued area for ecological research. In 1946, The Arctic Research Laboratory was established in Point Barrow, Alaska under the contract of the Office of Naval Research. This launched an interest in exploring the Arctic examining animal cycles, permafrost and the interactions between indigenous peoples and the Arctic ecology. During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit of Alaska as they have become extremely accustomed to adapting to ecological and climate variability. (en) La ecología ártica es el estudio científico de las relaciones entre los factores bióticos y abióticos en el Ártico, la región al norte del Círculo Polar Ártico (66 33’). Esta región se caracteriza por condiciones estresantes como resultado del frío extremo, la escasez de precipitaciones, una temporada de crecimiento limitada (50 a 90 días) y prácticamente ausencia de luz solar durante todo el invierno. El Ártico comprende taiga (o bosque boreal) y biomas de tundra, que también dominan elevaciones muy altas, incluso en los trópicos. Existen ecosistemas sensibles en toda la región del Ártico, que están siendo impactados dramáticamente por el calentamiento global. Los primeros habitantes del Ártico fueron la subespecie neandertal. Desde entonces, muchas poblaciones indígenas han habitado la región hasta el día de hoy. Desde principios del siglo XX, cuando Vilhjalmur Stefansson dirigió la primera gran expedición ártica canadiense, el Ártico ha sido un área valiosa para la investigación ecológica. En 1946, el Laboratorio de Investigación del Ártico se estableció en Punta Barrow, Alaska, como parte de las iniciativas de la Oficina de Investigación Naval. Esto despertó un interés en explorar el Ártico examinando los ciclos de los animales, el permafrost y las interacciones entre los pueblos indígenas y la ecología del Ártico. Durante la Guerra Fría, el Ártico se convirtió en un lugar donde Estados Unidos, Canadá y la Unión Soviética realizaron importantes investigaciones que han sido fundamentales para el estudio del cambio climático en los últimos años. Una de las principales razones por las que la investigación en el Ártico es esencial para el estudio del cambio climático es que se considera que sus efectos se habrán de percibir más rápida y drásticamente en las latitudes más altas del mundo, ya que se pronostican temperaturas superiores al promedio para el noroeste de Canadá y Alaska. Desde un punto de vista antropológico, los investigadores estudian a los pueblos nativos inuit de Alaska, debido a que se han podido adaptar a la extrema variabilidad ecológica y climática de la región.
