A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal ...
Terrestrial ecosystems found in the boreal (or taiga) regions of North America and Eurasia cover 17% of the Earth's land surface, and contain more than 30% of all carbon present in the terrestrial biome. [1] In terms of carbon storage, the boreal region consists of three ecosystems: boreal forest, peatland, and tundra. Vast areas of the globe ...
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]
A hemiboreal forest has some characteristics of a boreal forest to the north, and also shares features with temperate-zone forests to the south. A significant number of nut species, such as aspens, oaks, maples, ash trees, birches, beeches, hazels, and hornbeams, can be found here.
The Boreal Mountains and Plateaus Ecoregion is unique among other British Columbia ecoregions in that it contains several volcanoes of late Tertiary and Pleistocene age. Level Mountain and Mount Edziza are the most prominent volcanoes of this ecoregion which reach elevations of 2,134 m (7,001 ft) and 2,787 m (9,144 ft), respectively.
The Pre-Boreal began with a sudden rise in temperature that abruptly changed this ecosystem. Forest replaced the open lands in Europe, and forest-dwelling animals spread from southern refugia and replaced the ice-age tundra mammals; new climax ecosystems developed. The old fauna persisted in Central Asia, but were soon hunted out, as they were ...
Boreal (age), the first climatic phase of the Blytt-Sernander sequence of northern Europe, during the Holocene epoch; Boreal climate, a climate characterized by long winters and short, cool to mild summers; Boreal ecosystem, an ecosystem with a subarctic climate in the Northern Hemisphere; Boreal forest, a biome characterized by coniferous forests
60% of the land in the European Union part of the region is covered by forest, but most of this is commercial plantings. Less than 5-10% of the forest is old growth. The typical western taiga forest contains Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) growing on shallow soil covered in moss, lichen and ericaceous shrubs. [1]
