Publikováno v: PLoS ONE, Vol 12, Iss 6, p e0180042 (2017)

We collected relevant observational and measured annual-resolution time series dealing with climate in northern Europe, focusing in Finland. We analysed these series for the reliability of their temperature signal at annual and seasonal resolutions.

Aim The aim was to decipher Europe‐wide spatio‐temporal patterns of forest growth dynamics and their associations with carbon isotope fractionation processes inferred from tree rings as modulated by climate warming. Location Europe and North Afri

Most of the carbon (C) stored in temperate arable soils is present in organic matter (OM) intimately associated with soil minerals and with slow turnover rates. The sensitivity of mineral-associated OM to changes in temperature is crucial for reliabl

Priming effect increases with depth in a boreal forest soil

Publikováno v: Soil biology & biochemistry. 99:104-107

Climate warming increases labile carbon (C) inputs to soil through increased photosynthesis and C allocation belowground. This could counterintuitively lead to losses of soil C via priming effects (PE): the stimulation of soil organic matter (SOM) de

Oak decline analyzed using intraannual radial growth indices, δ13C series and climate data from a rural hemiboreal landscape in southwesternmost Finland

Publikováno v: Environmental Monitoring and Assessment. 186:4697-4708

Decline of pedunculate oak (Quercus robur L.) was studied in SW Finland. This is a region where the species is growing near its northern distributional limit globally and a recent decline of mature trees has been described regionally. Tree rings of d

The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the last century are likely to have had a profound effect on the physiology of trees: altering the carbon and water fluxes passing thr

Contrasting effects of increased carbon input on boreal SOM decomposition with and without presence of living root system of Pinus sylvestris L

Publikováno v: Plant and Soil. 377:145-158

We studied how the availability of carbon affects the decomposition of soil organic matter (SOM) in the presence of living root system compared to bare SOM treatments without roots. We measured the effect of living Pinus sylvestris L. root systems on

Temperature sensitivity of decomposition in a peat profile

Autor: Jari Liski, Hannu Fritze, Markku Oinonen, Emmi Hilasvuori, Raija Laiho, Päivi Mäkiranta, Pekka Vanhala, Kristiina Karhu, Anu Akujärvi, V. Palonen

Publikováno v: Soil Biology and Biochemistry. 67:47-54

Soil microbes favour easily decomposable organic compounds, and, consequently, soil organic matter tends to enrich with recalcitrant carbon compounds. In theory, this leads to an increasing temperature sensitivity of decomposition towards older fract

On the Eve of Urbanization: Bayesian Model Dating for Medieval Turku

Autor: Emmi Hilasvuori, Kari Uotila, Pentti Zetterberg, H Mehtonen, Markku Oinonen

Publikováno v: Radiocarbon. 55:1265-1277

The era of early urbanization in Finland coincides with large variations in the atmospheric radiocarbon concentration around the 13th–14th centuries AD. Therefore, the uncertainties of an individual 14C date are too large to support studies of this

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 73:383-387

Within a project on climate in Europe during the past few hundred years we have collected a record on stable isotope ratios 13 C/ 12 C and 18 O/ 16 O in tree ring cellulose from pine trees in northern Finland. The records cover the time interval 1600
