We investigated the thermal acclimation of photosynthesis and respiration in black spruce
seedlings [Picea mariana (Mill.) BSP] grown at 22/14° C [low temperature (LT)] or 30/22° C …

Fast kinetics of chlorophyll a fluorescence in three Norway spruce ecotypes was
investigated. Spruce ecotypes that come from different parts of the provenance regions were …

Low temperatures represent the most important environmental stress for plants at the
treeline ecotone; however, drought periods at the semiarid treeline could modify …

1. There are conflicting reports concerning the adaptive features of tree populations
originating from cold, high‐altitude environments. We hypothesize that such trees will …

Both aboveground and belowground climate affects net primary production (NNP) and forest
growth. Little is known about how above and belowground factors interact. The BIOMASS …

Five-year-old Norway spruce (Picea abies (L.) Karst.) seedlings were subjected to three
simulated growing seasons in controlled environment chambers. Plants were acclimated to …

Studies were undertaken with the aim of examining whether, in conifers growing in regions
with severe winters the photosynthetic depression during winter is the result of oxidative …

Most research on the occurrence and stability of alpine timberlines has focused on
correlations between adult tree growth and mean temperatures rather than on specific …

In the context of an increased risk of extreme drought events across Europe during the next
decades, the capacity of trees to recover and survive drought periods awaits further …

We explored the effect of high‐growth temperatures on a dominant North American boreal
tree, black spruce [Picea mariana (Mill.) BSP]. In 2004 and 2005, we grew black spruce at …
