Decreasing snow cover alters functional composition and diversity of Arctic tundra

P Niittynen, RK Heikkinen, M Luoto - … of the National Academy of Sciences, 2020 - pnas.org
The Arctic is one of the least human-impacted parts of the world, but, in turn, tundra biome is
facing the most rapid climate change on Earth. These perturbations may cause major …

Microgeography, not just latitude, drives climate overlap on mountains from tropical to polar ecosystems

DH Klinges, BR Scheffers - The American Naturalist, 2021 - journals.uchicago.edu
An extension of the climate variability hypothesis is that relatively stable climate, such as that
of the tropics, induces distinct thermal bands across elevation that render dispersal over …

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 …

Microclimate relationships of intraspecific trait variation in sub‐Arctic plants

J Kemppinen, P Niittynen - Oikos, 2022 - Wiley Online Library
Within‐species trait variation is a substantial part of plant functional diversity. However, this
intraspecific trait variation (ITV) is rarely investigated in relation to a key characteristic of the …

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 …

Plant trait‐environment relationships in tundra are consistent across spatial scales

T Rissanen, P Niittynen, J Soininen, AM Virkkala… - …, 2023 - Wiley Online Library
Patterns and processes sha** ecosystems vary across spatiotemporal scales. As plant
