Antarctica and the surrounding Southern Ocean are facing complex environmental change.
Their native biota has adapted to the region's extreme conditions over many millions of …

Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation
determines ground temperature, light conditions, and moisture availability during winter. It …

Inference about future climate change impacts typically relies on one of three approaches:
manipulative experiments, historical comparisons (broadly defined to include monitoring the …

Climate change has a disproportionally large impact on alpine soil ecosystems, leading to
pronounced changes in soil microbial diversity and function associated with effects on …

Because of severe abiotic limitations, Antarctic soils represent simplified systems, where
microorganisms are the principal drivers of nutrient cycling. This relative simplicity makes …

Environmental manipulation studies are integral to determining biological consequences of
climate warming. Open Top Chambers (OTC s) have been widely used to assess summer …

Historically, slow decomposition rates have resulted in the accumulation of large amounts of
carbon in northern peatlands. Both climate warming and vegetation change can alter rates …

The polar regions are experiencing rapid climate change with implications for terrestrial
ecosystems. Here, despite limited knowledge, we make some early predictions on soil …

Climate warming is expected to increasingly influence boreal peatlands and alter their
greenhouse gases emissions. However, the effects of warming on N 2 O fluxes and the N 2 …

Arctic tundra currently stores half of the global soil carbon (C) stock. Climate warming in the
Arctic may lead to accelerated CO2 release through enhanced decomposition and turn …
