Sentences with word «latewood»

[Maximum latewood density values are calibrated in the same way as with the ring width data using the statistical procedures described in section 10.2.4.]

Technical considerations / limitations have precluded the construction of bcp maximum latewood density (MLD) chronologies.

Collectively, each couplet of earlywood and latewood comprises an annual growth increment, more commonly called a tree ring.

This is similar to what has been noted, as discussed in the previous emails, with high - latitude summer - temperature sensitive maximum latewood tree - ring density chronologies (e.g. Briffa and coworkers) and it may relate to the same factors that have been discussed in that context.

The part of an annual tree ring that forms in the latter part of the growing season is called latewood.

Other investigators had measured the annual latewood density for trees from the British Isles and the northeastern Mediterranean for rings formed from 1978 back to 1725.

(I'm discovering dozens of papers just on latewood density response to various factors, and the divergence issue)

Ring - width as well as early and latewood width can be separately stored.

Generally, two values are measured in each growth ring: minimum density and maximum density (representing locations within the earlywood and latewood layers, respectively), although maximum density values seem to be a better climatic indicator than minimum density.

Each seasonal increment consists of a couplet of earlywood (a light growth band from the early part of the growing season) and denser latewood (a dark band produced towards the end of the growing season), and collectively they make up the tree ring.

The focus here is on the use of one growth parameter: maximum latewood density (MXD).

Collectively, each couplet of earlywood and latewood comprises an annual growth increment, more commonly called a tree ring.

Records of tree - ring characteristics such as their width (TRW) and density (usually the maximum density of the wood formed towards the end of the growing season — the «maximum latewood density» — MXD) are widely used to infer past variations in climate over recent centuries and even millennia.

Douglas - fir typically has very well - defined annual rings, with a sharp definition between earlywood (light colored cells) and latewood (dark colored cells).

The density of the latewood in a particular tree ring reflects the August temperature that year.

When viewed in detail (Fig. 10.1) it is clear that they are made up of sequences of large, thin - walled cells (earlywood) and more densely packed, thick - walled cells (latewood).

It basically says that ringwidth is a function of: age trend + climate signal + endogenous (local) disturbances + exogenous (standwide) disturbances + unexplained variation Basically, this concept also underlies all other dendro proxies, be it maximum latewood density or stable isotope ratios, even though there are variations, e. g. age trend in density data is treated differently from ring width data).

I will bet you a case of beer that the relationship between growth rates / latewood density and temperature is ASSUMED, not documented by detailed greenhouse studies (which is the only way I can think of for establishing such a relationship).

When both temperature and illumination (day length, solar intensity) become optimum, a great deal of mass is produced (latewood).

Are we agreed that trees at some sites can be sensitive to growing season temperature and reflect this in changes in ringwidth or latewood density?

The result is that «noise» can readily cause the tree - ring width (or latewood density, or whatever) to be extremely far away from the median.

The latewood density is interesting.

This problem should be worst in late summer (after seasonal snow has melted) and and early fall (latewood density).

Tree rings are made up of both earlywood and latewood, which vary markedly in average density and these density variations can be used, like ring width measurements to identify annual growth increments and to crossdate samples Parker 1971.]

The earlywood is made up of large, thin - walled tracheid cells and the latewood, of smaller, thicker - walled cells.

The earlywood is made up of large and relatively thin - walled cells (tracheids); latewood is made up of small thick - walled tracheids.

Latewood is composed of small thick walled tracheid cells compressed tightly together that appear much darker in color.
