studies is still in an initial phase and the number of fungal species used so far reflect only a small spectrum of described species, screening the potential application of further decay fungi may prove to be very valuable for the future progress of dendrochronology.(den-droh-cruh-NOL-uh-gee) means “the study of tree time.” Usually called tree-ring dating, dendrochronology is a science based on the fact that every growth season a tree adds a new layer of wood to its trunk.Tree-ring analysis requires observation and pattern recognition.Each year a tree’s growth ring has two parts; one is wide and light colored, and the other is narrow and dark. This grows during the wet spring and early summer when the tree has a lot of sap, and the cambium cells giving rise to the trunk growth are large and thin walled.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. 1979, 1986 © Harper Collins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012 Cite This Source (děn'drō-krə-nŏl'ə-jē) The study of growth rings in trees for the purpose of analyzing past climate conditions or determining the dates of past events.Because trees grow more slowly in periods of drought or other environmental stress than they do under more favorable conditions, the size of the rings they produce varies.By observing the pattern formed by a tree's rings, scientists can learn about the environmental changes that took place during the period in which it was growing.They can also match up the pattern in trees whose age is known to the pattern in a piece of wood found at an archaeological site, thereby establishing the approximate date of the site.
The second piece of wood is taken from a supporting beam in a house built at the beginning of the twentieth century.The study of annual rings in trees in order to analyze past climate conditions or to determine the date of past events.Trees grow more slowly in periods of drought or other environmental stress than they do under more favorable conditions, and thus the annual rings they produce are smaller.For the Aegean world, at the moment we do have a series of rings reaching back to 363 CE.There is another series (with a length of 1503 years) that does not fit to this series: there is a gap of several centuries.
