TL;DR: It is concluded that the growth of trees is not C-limited, with the key to understanding future responses to climate change being turnover of soil organic matter and nutrient cycling.

TL;DR: It is found that across all treatments, NDVI is correlated with aboveground biomass, aboveground plant biomass, and ecosystem C fluxes including gross ecosystem production (GEP), ecosystem respiration (ER) and net ecosystem production, providing a basis for linking remotely sensed NDVI toAboveground biomass and ecosystem carbon flux.

TL;DR: A new framework that attempts to reconcile the role of soil fauna within the C and N cycle with biogeochemical models and soil food web models is introduced and a simple stoichiometric approach is considered to integrate the understanding of N mineralization and immobilization with the C:N ratio of substrates and faunal life history characteristics.

TL;DR: The authors showed that enhanced plant growth in the European Arctic could result in an overall increase in carbon being released to the atmosphere, and this effect must be considered in the context of soil-carbon changes.

TL;DR: Over the time scale of a few weeks to months, warming-induced changes in the microbial community in arctic soils will amplify the instantaneous increase in the rates of CO2 production and thus enhance C losses potentially accelerating the rate of 21st century climate change.
