Dendrochronology-the scientific method of dating tree rings-has been widely applied to reconstruct past environmental events such as paleoclimatic variation, climate change, wildfire history, droughts, floods, and glacial dynamics. However, its application to track the historical deposition of persistent organic pollutants remains underexplored. In this study, we analyzed annual growth rings of Pinus sylvestris to reconstruct the temporal dynamics of hexachlorocyclohexane (HCH) isomer contamination at the Bailín landfill site (Sabiñánigo, northeastern Spain) over the period 1979-2018.

Responses of tree radial growth to climate are usually species-specific. Northwestern Yunnan has become a hotspot for the study of dendrochronology due to its sensitivity to climate change and the relative integrity of vegetation preservation. In this paper, we take three dominant conifers-, and -as the research objects and analyze their tree-ring width chronologies in order to reveal the main climate factors affecting tree growth in northwestern Yunnan and to evaluate species-specific variation in climate response.

Pinus banksiana exhibits remarkable ecological adaptability, thriving across diverse environments in the Canadian boreal zone, including clay deposits, fast-draining glacial tills, and rocky outcrops. However, projected rising temperature and increasing vapor pressure deficit (VPD), could increase the species' vulnerability, particularly in dry regions. In this study, we measured basal area increment (BAI) and physiological responses from isotopic fractionation across a soil gradient including three sites in the boreal mixed wood of western Quebec, Canada.

Late spring frost (LSF) severely impacts tree growth and forest productivity, with global warming potentially altering LSF risk due to asymmetric changes in vegetation onset and frost timing. However, reconstructing past frost regimes with climatic and phenological data remains challenging. Using phenological models, high-resolution climate and tree-ring data, we identified damaging LSF on European beech at two sites in the Swiss Jura mountains over nine decades.

Applying a centennial or millennial perspective to disturbance regimes permits an understanding of how these events have varied in the past in relation to climate change. Correctly interpreting this variability is crucial when preparing sustainable forest management practices for future warming. The eastern spruce budworm (Lepidoptera) is the most important biotic disturbance in the eastern Canadian boreal forest.
