Abstract Plants have evolved numerous strategies for surviving the harsh conditions of the Arctic. One strategy for Arctic evergreen and semi‐evergreen species is to photosynthesize beneath the snow during spring. However, the prevalence of this ph

Sloane and Sadava, in 1975, proposed that auxin-induced cell wall acidification is largely due to carbonic acid derived from respired CO 2 . In this paper we show that the pH values calculated by Sloane and Sadava from measured CO 2 concentrations do

The relationship of growth to plant water potential was studied in several arctic tundra species by experimentally altering the water regimes on excised tussocks, by clipping leaf area, and by clipping roots. Most species, including evergreen shrubs,

The objectives of this study were to (1) provide a baseline estimate of soil and plant element concentrations for an intensive research site at Imnavait Creek in northern Alaska, and (2) examine the relationships between soil and plant elements in an

Evapotranspiration was measured periodically from late June through mid-August 1978 in Eriophorum vaginiatum tussock tundra near Eagle Creek, Alaska. The average evapotranspiration rates from tussock and intertussock areas were 0.8 mm d−1 and 1.3 m

The response of seed germination to substrate water potential was determined for several plant species of the arctic tundra. Seeds were collected from Cape Thompson and Eagle Summit, Alaska and germinated on dialysis membranes over water solutions of
