In lieu of using surface
growth rings or internal growth lines in shells to directly age individual gastropod specimens, individual age can often be estimated from measurements such as total shell length and lip thickness, provided that population growth rates have already been established.
The number of the
growth rings on each scale was verified by three different people and the final results comprised the number of the most frequent
growth rings.
Pederson's team compared the ship's
growth rings with those of living trees and wood from historic structures.
Schematic view of a section of two
growth rings. Early wood--or spring wood--contains more and larger vessels.
Particularly, the segregation of wood is less noticeable in [D.sub.L] (Figure 2c) due to a high variability between
growth rings. Nevertheless, a tendency of [D.sub.L] decrease based on segregation year was observed.
Hubacz holds a cross-section of a red oak that shows the
growth rings. (2) Close-up of a red oak cross-section showing decreased growth in a red oak resulting, according to forester Ross P.
The goal of this study was to investigate the effects of thinning and fertilization on mechanical properties of loblolly pine (Pinus taeda L.) strands associated with
growth ring number and height.
Since the initial application of daily
growth rings in the aging of larval fishes by Brothers et al.
grandis is one of the tropical species that shows clear
growth rings and suitable for climatic analysis (Chowdhury 1964, Detienne 1989, Bhattacharyya & Shah 2009).
By studying
growth rings from coastal shrubs and lake sediments, the researchers discovered that the region hasn't experienced an event of such magnitude during the past 1,000 years.
Similar to annual
growth rings of trees, otoliths' rings can be counted to indicate a fish's age and annual growth rate, estimated by measuring distances between each new ring.
