متن کاملChromite composition as evidence of metamorphism in komatiites, greenstone belt, Mozambique
Archaean komatiites of the greenstone belt in Manica area, western Mozambique contains accessory amount of disseminated chromite grains. The komatiite rocks comprise peridotitic and basaltic komtiite. These komatiites are affected by regional metamorphism as all of the studied area. It is observed that only chromian spinel is preserved as the primary mineral and that all the other primary miner...
متن کاملChironomid-based classification of lakes in western Finnish Lapland
For the implementation of the Water Framework Directive we need to develop an informative and cost-effective set of biological monitoring and assessment methods, especially for remote areas. Chironomids are known to be an abundant and speciesrich group that dominate the aquatic macroinvertebrate assemblages in the north and therefore should be an integral part of monitoring and assessment plans...
متن کاملMicroparasites of three species of shrews from Finnish Lapland
Forty-five common shrews, Sorex araneus, caught in 1997; and 48 S. araneus, 21 masked shrews, Sorex caecutiens, and 25 pygmy shrews Sorex minutus trapped in 1998 at Kilpisjärvi in northern Finland were examined for microparasites. Bartonella sp. was found in blood smears of S. araneus both in 1997 (prevalence 15%) and 1998 (10%) but no blood parasites were found in S. caecutiens or S. minutus. ...
متن کاملPhytoplankton ecology of subarctic lakes in Finnish Lapland
The climate is warming and it is most noticeable in the arctic and subarctic areas, where the warming trend is expected to be the greatest. Arctic and subarctic freshwater ecosystems, which are a very characteristic feature of the northern landscape, are especially sensitive to climate change. They could be used as early warning systems, but more information about the ecosystem functioning and ...
