Dendrochronology has been applied as a research tool to many natural scientific disciplines, and it also constitutes its own line of research in many respects. Below is a list of various subdisciplines of dendrochronology, each of which has a list of recent publications that were authored or coauthored by someone currently at the Laboratory of Tree-Ring Research. Direct e-mail links to authors are provided to aid in requesting reprints or more information about any particular article or general research endeavor.
