Genetologic Research

Dendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was invented and developed during the 20th century originally by the astronomer A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona.

Other branches of Dendrology:

dendroarchaeology: The science that uses tree rings to date when timber was felled, transported, processed, or used for construction or wooden artifacts. Example: dating the tree rings of a beam from a ruin in the American Southwest to determine when it was built.

dendroclimatology: The science that uses tree rings to study present climate and reconstruct past climate. Example: analyzing ring widths of trees to determine how much rainfall fell per year long before weather records were kept.

dendroecology: The science that uses tree rings to study factors that affect the earth’s ecosystems. Example: analyzing the effects of air pollution on tree growth by studying changes in ring widths over time.

dendrogeomorphology: The science that uses tree rings to date earth surface processes that created, altered, or shaped the landscape. Example: analyzing changes in tree growth patterns via tree rings to date a series of landslide events.

dendroglaciology: The science that uses tree rings to date and study past and present changes in glaciers. Example: dating the inside rings of trees on moraines to establish the approximate date of a glacial advance.

dendrohydrology: The science that uses tree rings to study changes in river flow, surface runoff, and lake levels. Example: dating when trees were inundated to determine the sequence of lake level changes over time.

dendropyrochronology: The science that uses tree rings to date and study past and present changes in wildfires. Example: dating the fire scars left in tree rings to determine how often fires occurred in the past.

dendroentomology: The science that uses tree rings to date and study the past dynamics of insect populations. Example: dating the growth suppressions left in tree rings from western spruce budworm outbreaks in the past.
