  • Warming temperatures and interactions between plants are the main drivers of changes in Arctic plant communities in response to climate change, and there is no evidence of overall biotic homogenization.

  • The feedback between the terrestrial carbon cycle and climate is one of the largest uncertainties in current projections of future climate, with the long-term sensitivity of carbon in peatlands remaining unclear. The combination of non-disturbing in situ measurements of carbon dioxide respiration rates and isotopic composition of respired CO2 in subarctic peatland experiments now shows that warming accelerates respiration rates of these subsurface carbon reservoirs to a much larger extent than was previously thought.

  • The release of ancient carbon from thawing permafrost is thought to have an important impact on global biogeochemistry through positive feedbacks. Here Dean and colleagues show that in Siberian permafrost, warming could liberate more contemporary carbon relative to aged counterparts.

  • Field experiments across aquatic and terrestrial ecosystems show that biodiversity positively affects carbon and nitrogen cycling in leaf litter decomposition, indicating that reduced decomposition caused by biodiversity loss would modify the global carbon cycle and limit the nitrogen supply to the organisms at the base of the food chain.

  • Stef Bokhorst et al. simulate a warming scenario in Antarctic soil under laboratory conditions and report the germination and growth of sixteen non-native plant species. These experimental results, combined with calculations of thermal germination requirement at +3 °C and +5 °C warming scenarios demonstrate that the risk of establishment by non-native species in Antarctica may be greater than previously suggested by species distribution modelling approaches.
