Sorry, no etymologies found.
For example, in nearly all existing records, data for the most recent period is based on tree rings that on average have a high cambial age as compared to the earlier parts of the record.
(SB trees grew faster in diameter) 1. I agree with others that the strip bark phenomenon is likely caused by root death, and the root death is likely caused by physical injury by rocky substrate. (cf. wave regeneration in fir) 2. Root death will cause cambial death above it.
Conventional wisdom regarding the mechanism includes two notions: first, less cambial tissue means the existing, limited number of cambial cells will get more carbohydrate and therefore grow faster.
In this connection cambial activity occurs at precisely this period.
Ring development and most cambial activity therefore is a result of daytime conditions or at least weighted towards the day and so it would seem logical that the trees would respond more strongly to daytime conditions.
Dendrochronological work at Sheep Mountain in the White Mountains, CA has demonstrated that bristlecone pine trees in two forms, full-bark and strip-bark, have experienced different cambial growth rates over the past century or longer.
When almost all new biomass goes into cambial enlargement, however, a growth increase of 60% or more is observed over the past two centuries.
Experience has indicated that many of the oldest five-needled pines have experienced cambial dieback to varying degrees.
To build RCS chronologies from the whole data set containing different sites and species, we analyzed the growth levels and trends of the individual ring width series after aligning them by cambial age and classifying them into two groups, one with age trends having a weakly "linear" form and one with age trends that are clearly "nonlinear" see Web fig.
Arithmetic mean curves of individual ring width series from different sites after aligning by cambial age.
