Mineral Content of Tundra and Forest Tundra Plants in Fennoscandia
The mineral composition of plant material has been studied in the Finnish and Norwegian IBP tundra projects (Sonesson et al., 1975). Some mineral analyses of tundra plants in USSR were givenExpand
Morphogenesis in Micrasterias.
Polar lipids and net photosynthesis potential of subarctic Diapensia lapponica
Abstract The overall net photosynthesis potential of Diapensia lapponica was very low. It was highest at the end of August (11.1 μmol CO 2 (μmol chlorophyll) −1 hr −1 ) and decreased during theExpand
Description of Fennoscandian Tundra Ecosystems
The tundra landscape of Fennoscandia is mostly alpine. The southernmost areas above the tree line, with annual mean air temperatures below 0° C, are found at about 59° N in southern Norway. AExpand
Analysis of Precipitation at Fennoscandian Tundra Sites
Nutrient input through precipitation is noticeable particularly in ombrotrophic habitats such as the oligotrophic IBP sites dominated by lichens at Hardangervidda, Norway and at Kevo in Finland;Expand
The effect of different night conditions on the CO2 fixation in a lichen Xanthoria parietina
It seems that plants need an unproductive period during the day to survive and this can be induced by fluctuations in light and/or temperature. Expand
Nitrogen fixation in subarctic lichens
N2 fixation is not well adapted to average arctic conditions and this may account for the low nitrogen content of arctic soils, according to local climatic differences for nitrogen supply. Expand
