The interpretation of stable isotopes in a dendroecological framework can provide powerful insights into how trees adjust physiologically in response to the environment. This symposium aims to bring together researchers who use stable isotopes in tree rings to address ecophysiological responses to environmental changes from intra-annual to multi-decadal resolution. We hope this symposium will enable fruitful discussions and new ideas and help identify new research directions aiming to foster new collaborations between researchers within the scientific community. Therefore, we welcome submissions presenting new scientific approaches on tree-ring isotopic observations and comparisons to data and models based on forest dynamics, ecophysiology, hydrology, biogeochemistry and, remote sensing. Specific topics this session is anticipated to include:

1.         Changes in carbon isotope discrimination and water-use efficiency in response to environmental changes (climate, atmospheric CO2, atmospheric deposition).

2.         Seasonal and environmental changes recorded in intra-annual isotopic variations (Studies using xylogenesis, Quantitative wood anatomy, and isotopes).

3.         Changes in water source and source versus relative humidity interactions. (Oxygen isotopes)

4.         Using d15N in tree rings to assess changes in environmental conditions (Nitrogen availability, atmospheric deposition).

5.         Impacts of climate change on plant functioning under different environmental conditions (dry versus humid) (multi-species interactions).

6.         Forest responses to disturbances (e.g., fires, outbreaks, etc.).

7.         Improvements of vegetation models using multiple tree ring parameters.

8.         Projections of forest responses to future climate change informed by stable isotopes.
