Exploring wood anatomy, chemistry and climate through the world’s longest living organisms, North American Bristlecone Pine

Investigator

Title of the project Exploring wood anatomy, chemistry and climate through the world’s longest living organisms, North American Bristlecone Pine
Primary and secondary scientific disciplines Biological sciences, Earth and related environmental sciences
Description of the project Characteristics and main objectives of the research project:

  • World’s oldest living tree North American Bristlecone pine is a remarkable species, constituting tree-ring growth series which span around eight millennia.
  • The extraordinary longevity of the species provides us with the opportunity to analyze past climatic fluctuations at exceptionally long scale with yearly and even sub-annual resolution.
  • Microanatomical analysis of tree rings of this species will provide results of so far unprecedented length.
  • Bristlecone pine chronologies have a well-established connection with past climatic changes and frost rings phenomenon with climate fluctuations associated with climatically effective volcanic eruptions. A secondary proxy for such forcing and other climatically derived patterns is lignification.
  • In this project, the unique bristlecone pine tree-ring archive at the Laboratory of Tree-Ring Research will be explored to develop long records of blue-ring (unlignified tree rings structures) data and these explored at a cellular level to develop new lines of proxy evidence.

The project is conducted in cooperation with the Laboratory of Tree Ring Research, University of Arizona, Tucson, USA.
