(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-11)
      Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear whether all phenophases, particularly those later in the season, will shift in unison or respond divergently to warming. Here, we present the largest synthesis to our knowledge of ...

    • Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome 

      Rheubottom, Sarah I.; Barrio, Isabel C.; Kozlov, Mikhail V.; Alatalo, Juha M.; Andersson, Tommi; Asmus, Ashley L.; Baubin, Capucine; Brearley, Francis Q.; Egelkraut, Dagmar; Ehrich, Dorothee; Gauthier, Gilles; Jonsdottir, Ingibjørg; Konieczka, Sophia; Lévesque, Esther; Olofsson, Johan; Prevéy, Janet S.; Slevan-Tremblay, Guillaume; Sokolov, Aleksandr; Sokolova, Natalia; Sokovnina, Svetlana; Speed, James David Mervyn; Suominen, Otso; Zverev, Vitali; Hik, David S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-03)
      Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current levels of invertebrate herbivory vary across the Arctic is limited and generally restricted to a single host plant or a small group of species, so predicting future change remains ...

      The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental factors shape plant structure and function is crucial for predicting the consequences of environmental change for ecosystem functioning. Here we explore the biome-wide relationships ...

      <p><i>Aim - </i>Plant functional groups are widely used in community ecology and earth system modelling to describe trait variation within and across plant communities. However, this approach rests on the assumption that functional groups explain a large proportion of trait variation among species. We test whether four commonly used plant functional groups represent variation in six ecologically ...

      <p><i>Motivation</i>: The Tundra Trait Team (TTT) database includes field‐based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical questions about plant strategy and trade‐offs, trait–environment relationships and environmental filtering, and trait variation across spatial scales, to validate satellite ...
