Forests constitute important ecosystems in the global carbon cycle. However, how trees and
environmental conditions interact to determine the amount of organic carbon stored in forest …

Alpine and Arctic treeline expansion depends on establishment of tree seedlings beyond the
current treeline, which is expected to occur with climate warming. However, treelines often …

Unprecedented modern rates of warming are expected to advance boreal forest into Arctic
tundra, thereby reducing albedo,–, altering carbon cycling and further changing climate …

Little is known about how soil properties control tree growth at its upper limit. This paper
reviews the state of knowledge and discusses the results specifically related to ecozones, to …

Treelines advance due to climate warming. The impacts of this vegetation shift on plant–soil
nutrient cycling are still uncertain, yet highly relevant as nutrient availability stimulates tree …

Only a few studies have addressed the soil and foliar carbon: nitrogen: phosphorus (C: N: P)
stoichiometry in alpine treeline ecotones. Moreover, information on the soil nutrient …

Climate warming may alter ecosystem nitrogen (N) cycling by accelerating N transformations
in the soil, and changes may be especially pronounced in cold regions characterized by N …

Climate change is expected to shift the boreal biome northward through expansion at the
northern and contraction at the southern boundary respectively. However, biome-scale …

Whether increased photosynthates under elevated atmospheric CO2 could translate into
sustained biomass accumulation in forest trees remains uncertain. Here we demonstrate …

Climate change has the potential to impact headwater streams in the Arctic by thawing
permafrost and subsequently altering hydrologic regimes and vegetation distribution …
