Seasonal climate manipulations result in species-specific changes in Leaf nutrient levels and isotopic composition in a sub-arctic bog.
Climate change in cold biomes not only involves higher summer temperatures, but also warmer springs and more winter precipitation. So far, little is known about species responses to these seasonal components of climate change. 2. We experimentally manipulated spring and summer temperatures and winte...
