Microorganisms, plants, and animals have successfully colonized cold environments, which
represent the majority of the biosphere on Earth. They have evolved special mechanisms to …

Leaf reddening during autumn in senescing, deciduous tree species has received
widespread attention from the public and in the scientific literature, whereas leaf reddening …

Insulation provided by snow cover and tolerance of freezing by physiological acclimation
allows Arctic plants to survive cold winter temperatures. However, both the protection …

Low temperature inhibits plant growth despite the fact that considerable rates of
photosynthetic activity can be maintained. Instead of lower rates of photosynthesis, active …

Freezing patterns in the high alpine cushion plants Saxifraga bryoides, Saxifraga caesia,
Saxifraga moschata and Silene acaulis were studied by infrared thermography at three …

Cold stress is a major environmental constraint to plant productivity. Cold-induced losses in
yield probably exceed those from all other causes, since both the severity and duration of …

Abstract Effects of plant age on resource acquisition and stress tolerance processes is a
largely unstudied subject in herbaceous perennials. In a field experiment, we compared …

Higher elevations and, early as well as late phase of growing season are expected to be
more stressful for plants in high altitudes. The present study was carried out on …

The ability to retain their photosynthetic capacity through the winter may be important for
plants in boreal conditions, where the growing season is relatively short and winter …

Camouflage has been reported as a defensive strategy in plants, while our understanding of
the evolution of such defensive coloration is still limited. In the present study, we tested the …
