We use the Western Canadian Taiga-Tundra and the Italian Alps as examples here to demonstrate that the infeasibility conditions do not need to manifest in terms of net CO2loss for the counterfactual tree scenario (X-Tr) to become infeasible. The thermodynamic infeasibility associated with prolonged ...

Treeline, the ecotone where forest transitions to alpine or tundra habitats, is considered susceptible to climate change (Körner, 1999, 2012; Holtmeier, 2009; Dial et al., 2022). For the purpose of comprehending forest dynamics in the context of ongoing climate change, it is essential to ...
Over the past decade, neither mean annual precipitation (MAP; Supplementary Fig.2) nor atmospheric N deposition (Supplementary Figs.2and3) experienced significant changes, whereas both mean annual air temperature (MAAT) and atmospheric CO2concentration significantly increased (P < 0.05; Supplementary...

We sampled a distinct and well-defined landscape unit within the GLV that is bound on the east by the tundra, on the south by alpine lakes, glaciers and meadows, on the west by the continental divide and on the north by steep cliffs. There is a large cliff face in the centre of our...

Figure 1. Map of the location of the AOI (Hol, Norway). Locations of field plots (see explanation in Section 2.2—Field methods) used for calibration of models appear as coloured circles along with the isolines. A graphical overview of the workflow is displayed in the chart in Figure 2....
A minority of the remaining species characterize alpine habitats other than true grasslands [26]: relict summit graminoid tundra in the alpine and subnival belts (Oxytropido-Elynetalia); subnival and alpine lime-rich shale screes and frozen slopes of the Alps and the Pyrenees of the nemoral ...
