An increasing Arctic-boreal CO2 sink offset by wildfires and source regions

A.-M. Virkkala

The paper shows the Arctic-Boreal Zone was an increasing CO2 sink from 2001-2020, but fire emissions offset this trend, making the region's overall sink statistically insignificant.

Relationships between aboveground plant traits and carbon cycling in tundra plant communities

K. Happonen, A.-M. Virkkala, J. Kemppinen, P. Niittynen, M. Luoto

This study models how plant traits influence carbon cycling in tundra ecosystems, finding that plant height, SLA, and LDMC strongly affect carbon dynamics, with functional diversity also playing a significant role.

The activity and functions of soil microbial communities in the Finnish sub-Arctic vary across vegetation types

S. Viitamaki, I. S. Pessi, A.-M. Virkkala, P. Niittynen, J. Kemppinen, E. Eronen-Rasimus, M. Luoto, J. Hultman

The study examines how microbial activity and functional potential vary across vegetation types in Finnish sub-Arctic soils, revealing differences in community composition and carbon turnover potential.

Woody plants constructing tundra soils

J. Kemppinen, P. Niittynen, A.-M. Virkkala, K. Happonen, H. Riihimaki, J. Aalto, M. Luoto

This study examines how woody plant coverage and height affect tundra soil moisture, temperature, and organic carbon stocks, finding coverage has a significant inverse correlation while height does not.

Snow is an important control of plant community functional composition

K. Happonen, J. Aalto, J. Kemppinen, P. Niittynen, A.-M. Virkkala, M. Luoto

The paper investigates factors influencing plant community functional composition in Arctic tundra, finding that snow is the most influential abiotic variable.
