External surface growth rings (annuli) or checks and internal growth lines representing a gastropod's age occur because of changes in seasonal shell growth rates that cause a change in the appearance in the shell as a result of variations in the inorganic/organic content and the shell crystal structure.

To achieve the goal, a system approach linked the results from previous studies (Jeong and Zink-Sharp 2012, 2013; Jeong 2013) that encompassed the information of anatomical structure from different forest managed trees associated with height and growth ring numbers to OSB mechanical properties of the current study.

The lumen diameter (DL) presented high variability between growth rings. This could be related to the decrease of growth rings due to increased age of the wood and, consequently, a higher proportion of early wood than latewood.

Although differences are low, in general ,specimens with narrowest rings and low density were more decayed than specimen with average or the widest xylem growth rings. The highest mass losses were observed at specimens with narrow rings (table 1).

In most trees, a single annual growing season results in the formation of a growth ring. These rings are xylem tissues, and as the tree ages, the inner (earliest) rings usually accumulate metabolic by-products and take on a different appearance.
