Nectar production may be a point of sensitivity that can help link primary and secondary
trophic responses to climate shifts, and is therefore important to our understanding of …

The upper elevational range limit of tree species (including treeline and non-treeline
species) is generally considered to result from either carbon limitation or sink limitation …

We tested if tree line trees are sink or resource limited by comparing the reactions in Scots
pine trees (Pinus sylvestris L.) to changes in resource availability (through nutrient addition …

Methane emissions from wetlands are temporally dynamic. Few chamber-based studies
have explored diurnal variation in methane flux with high temporal replication. Using an …

Dendrochronology has long used tree-rings to better understand climate-tree-growth
relationships within a site or across a region, with tree age often considered to contribute …

Background: Seedling germination and survival is a critical control on forest ecosystem
boundaries, such as at the alpine–treeline ecotone. In addition, while it is known that …

Soil temperature is proposed to affect the photosynthetic rate and carbon allocation in boreal
trees through sink limitation. The aim of this study was to investigate the effect of temperature …

Most hypotheses about controls over high-altitude forests, including treeline, the elevation
for upright woody plants, or timberline, the upper elevation for aggregated forest, suggest …

Key message A ratio of storage to growth of at least 8.4 and a balanced storage-growth
relationship might be essential for subalpine larch trees to persist at the treeline. Abstract …

Questions We investigated the importance of climate and herbivory on native and alien
conifer colonization of the birch‐dominated Fennoscandian tree line by addressing the …
