  • Abstract:

    The International Tree Ring Data Bank (ITRDB) is the most comprehensive database of tree growth worldwide. We are using this great ecological resource to understand the ecologic and evolutionary conditions associated with long-living individuals and species. We used the coordinates and maximum longevity of the 7000+ sites of the database together to build structural equations models that relate the maximum longevity achieved in each place with the environmental and intrinsic conditions that they experience. We also compared the importance of biotic and abiotic factors in determining the longevity expressed by singular individuals, as well as project this conditions to the whole World to find areas with a high-likelihood of hosting old individuals of their native species.
