Abstract Lake Thingvallavatn supports four trophic morphs of Arctic charr, Salvelinus alpinus (. ; two of the morphs are benthic (small and . Ecology of eutrophic, subarctic Lake Mývatn and the River Laxá. ; two of the morphs are benthic (small and large benthivorous charr) one exploits pelagic water. More).

Feeding ecology of Arctic charr in Lake Lønavatn, Norway, Cand.

Habitat use by four morphs of arctic charr,Salvelinus alpinus, was investigated in Thingvallavatn, Iceland, by sampling with pelagic and benthic gill nets. Sampling was done in May/June and August/September. Decomposition and sedimentation processes in oligotrophic, subarctic Lake Thingvallavatn, Iceland. Bathymetric distribution of Chironomidae (Diptera) in the oligotrophic Lake Thingvallatn, Iceland. Feeding ecology of Arctic charr in Lake Lønavatn, Norway, Cand.

Thingvallavatn is the only known lake in the world with four Arctic charr morphs utilizing the different food resources of the lake. Gunnar Steinn Jónsson. Among the morphs, a clear differentiation in life history characters, morphology, habitat, and food ecology, has occurred within 10 000 years.

Oligotrophic environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil .

Oligotrophic environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil, aquifers, ocean waters, and leached soils. Examples of oligotrophic organisms are the cave-dwelling olm; the bacterium, Pelagibacter ubique, which is the most abundant organism in the oceans with an estimated 2 1028 individuals in total; and the lichens with their extremely low metabolic rate.

This work brings new information about species distribution and dynamics of subarctic freshwater phytoplankton in relation to environmental factors. The phytoplankton of lakes in Finnish Lapland and other European high-altitude or high-latitude areas were compared. Most lakes were oligotrophic and dominated by flagellated species belonging to chrysophytes, cryptophytes and dinoflagellates.
