Arctic char species complex, distribution map Arctic char species complex, distribution map
The Arctic char species complex, sensu stricto, represent a key component of the marine and freshwater ecosystems of the north. Chars are stressed by factors such as fisheries, climate change and pollutants. We are possibly altering char biodiversity without documenting it and understanding its relevance. Concerted pan-Arctic biodiversity assessments, sustained research, and coordinated monitoring of chars are required to outline the scope of div...

The Arctic, as defined by summer temperature The Arctic, as defined by summer temperature
The Arctic is a region not easily delineated by one boundary or definition - it includes the Arctic Ocean and the land areas around it, including Greenland, Eurasia and North America. A climate definition of the Arctic is the 10 centigrade July isotherm. This limit roughly coincides with the treeline and represents a change in growing conditions for plants. As visible in the map, this also includes mountainous and alpine areas. The map also prese...
