Data from: The role of bryophytes for tree seedling responses to winter climate change: implications for the stress gradient hypothesis

Signe Lett, David A. Wardle, Marie-Charlotte Nilsson, Laurenz M. Teuber & Ellen Dorrepaal
1.When tree seedlings establish beyond the current tree line due to climate warming, they encounter existing vegetation, such as bryophytes that often dominate in arctic and alpine tundra. The stress gradient hypothesis (SGH) predicts that plant interactions in tundra become increasingly negative as climate warms and conditions become less harsh. However, for seedlings climate warming might not result in lower winter stress, if insulating snow cover is reduced. 2.We aimed to understand to if bryophytes...

Data from: Coordinated responses of soil communities to elevation in three subarctic vegetation types

G. F. Ciska Veen, Jonathan R. De Long, Paul Kardol, Maja K. Sundqvist, L. Basten Snoek & David A. Wardle
Global warming has begun to have a major impact on the species composition and functioning of plant and soil communities. However, long-term community and ecosystem responses to increased temperature are still poorly understood. In this study, we used a well-established elevational gradient in northern Sweden to elucidate how plant, microbial and nematode communities shift with elevation and associated changes in temperature in three highly contrasting vegetation types (i.e. heath, meadow and Salix vegetation). We found...

Data from: Soil fertility shapes belowground food webs across a regional climate gradient

Etienne Laliberté, Paul Kardol, Raphael K. Didham, François P. Teste, Benjamin L. Turner & David A. Wardle
Changes in soil fertility during pedogenesis affect the quantity and quality of resources entering the belowground subsystem. Climate governs pedogenesis, yet how climate modulates responses of soil food webs to soil ageing remains unexplored because of the paucity of appropriate model systems. We characterised soil food webs along each of four retrogressive soil chronosequences situated across a strong regional climate gradient to show that belowground communities are predominantly shaped by changes in fertility rather than...
