Article Synopsis
- The study explores how climate change and past nutrient availability affect Arctic vegetation growth, focusing on Salix glauca L. at archaeological sites in Southwest Greenland.
- The researchers found that plants in areas with historical nutrient enrichment had wider growth rings and responded more positively to temperature changes compared to those in nutrient-poor areas.
- The results indicate that past human activities enhance vegetation growth in the Arctic, suggesting that nutrient availability should be considered in future assessments of plant responses to climate change.
Insect defoliations are a major natural disturbance in high-latitude ecosystems and are expected to increase in frequency and severity due to current climatic change. Defoliations cause severe reductions in biomass and carbon investments that affect the functioning and productivity of tundra ecosystems. Here we combined dendro-anatomical analysis with chemical imaging to investigate the direct and lagged effects of insect outbreaks on carbon investment.

This could potentially lead to a major loss of wooden artefacts that are still buried within the region. Here, we carry out the first large-scale investigation of wood degradation within archaeological deposits in the Arctic.
