Macro-environment strongly interacts with warming in a global analysis of decomposition

This study analyzes decomposition responses to warming across global macro-environmental gradients, finding that warming effects vary significantly depending on moisture and temperature, with a threshold of 5.2°C for significant decomposition increase.

Long-term herbivore removal experiments reveal different impacts of geese and reindeer on vegetation and ecosystem CO2-fluxes in high-Arctic tundra

This study compares the impacts of geese and reindeer removal on vegetation and CO2-fluxes in high-Arctic tundra, finding that geese have stronger localized effects than reindeer.

Greening conceals evergreening: contrasting trends for a socio-ecological system in Arctic Europe

The paper shows increased biomass of allelopathic crowberry in Arctic Norway, contrasting with smaller increases in other plant types, and suggests potential negative impacts on reindeer and pastoral systems.

Towards rainy high Arctic winters: how ice-encasement impacts tundra plant phenology, productivity and reproduction

This study examines how winter ice-encasement from rain-on-snow events affects tundra plant phenology, productivity, and reproduction in the high Arctic, showing compensatory responses and trade-offs.

Long-term warming effects on the microbiome and nitrogen fixation of a common moss species in sub-Arctic tundra

This study examines how 20-year warming affects the bacterial communities and nitrogen fixation in a sub-Arctic moss species, finding shifts in community composition and reduced nitrogen fixation rates.

The total and active bacterial community of the chlorolichen Cetraria islandica and its response to long-term warming in sub-Arctic tundra

This study examines the bacterial communities in the lichen Cetraria islandica under long-term warming, finding shifts in community composition and increased activity of rare taxa.
