Fine-scale tundra vegetation patterns are strongly related to winter thermal conditions

…, RK Heikkinen, J Aalto, A Guisan, J Kemppinen… - Nature Climate …, 2020 - nature.com
Harsh winters are a characteristic element of Arctic ecosystems, yet the importance of winter
conditions for Arctic plant communities is still underrepresented in climate change impact …

Consistent trait–environment relationships within and across tundra plant communities

J Kemppinen, P Niittynen, PC le Roux… - Nature Ecology & …, 2021 - nature.com
A fundamental assumption in trait-based ecology is that relationships between traits and
environmental conditions are globally consistent. We use field-quantified microclimate and soil …

Modelling soil moisture in a high‐latitude landscape using LiDAR and soil data

J Kemppinen, P Niittynen, H Riihimäki… - Earth Surface …, 2018 - Wiley Online Library
Soil moisture has a pronounced effect on earth surface processes. Global soil moisture is
strongly driven by climate, whereas at finer scales, the role of non‐climatic drivers becomes …

Global maps of soil temperature

…, MB Ashcroft, P De Frenne, J Kemppinen… - Global change …, 2022 - Wiley Online Library
Research in global change ecology relies heavily on global climatic grids derived from
estimates of air temperature in open areas at around 2 m above the ground. These climatic grids …

SoilTemp: A global database of near‐surface temperature

…, G Kazakis, MA de Pablo, J Kemppinen… - Global change …, 2020 - Wiley Online Library
Current analyses and predictions of spatially explicit patterns and processes in ecology most
often rely on climate data interpolated from standardized weather stations. This interpolated …

Water as a resource, stress and disturbance shaping tundra vegetation

J Kemppinen, P Niittynen, J Aalto, PC le Roux, M Luoto - Oikos, 2019 - Wiley Online Library
Water is crucial for plant productivity and survival as a fundamental resource, but water
conditions can also cause physiological stress and mechanical disturbance to vegetation. …

[HTML][HTML] Microclimate temperature variations from boreal forests to the tundra

J Aalto, V Tyystjärvi, P Niittynen, J Kemppinen… - Agricultural and Forest …, 2022 - Elsevier
Microclimate varies greatly over short horizontal and vertical distances, and timescales. This
multi-level heterogeneity influences terrestrial biodiversity and ecosystem functions by …

Distance decay 2.0–a global synthesis of taxonomic and functional turnover in ecological communities

…, KK Kahilainen, J Kemppinen… - Global Ecology and …, 2022 - Wiley Online Library
Aim Understanding the variation in community composition and species abundances (ie, β‐diversity)
is at the heart of community ecology. A common approach to examine β‐diversity is …

Relationships between above‐ground plant traits and carbon cycling in tundra plant communities

K Happonen, AM Virkkala, J Kemppinen… - Journal of …, 2022 - Wiley Online Library
The trait composition and trait diversity of plant communities are globally applicable predictors
of ecosystem functioning. Yet, it is unclear how plant traits influence carbon cycling. This is …

A methodological guide to observe local‐scale geodiversity for biodiversity research and management

…, H Tukiainen, H Salminen, J Kemppinen… - Journal of Applied …, 2022 - Wiley Online Library
Current global environmental change calls for comprehensive and complementing approaches
for biodiversity conservation. According to recent research, consideration of the diversity …
