Validation of the ring count was confirmed by the second reader whose counts fell within the range of the original 3 readings for each otolith.
The measurement of settlement age was based on the pre-settlement ring count (+ 2 days), and size at settlement was based on the otolith radius to somatic length regression from measured standard length.
7m ring counts differed by 14 in tree 1, by 5 in tree 2 and by 7 in tree 3, while at the top (18.
However, mean fire-free interval calculated from records [greater than]150 yr long (as determined by total ring count for fire scarred trees or total ring count + MRFFP for fire scarred stumps) [TABULAR DATA FOR TABLE 2 OMITTED] can be combined with corresponding mean patch sizes (Table 1) to derive a reliable estimate of pre-1910 fire occurrence rates within those patches (fires/time/area).
The PLD was estimated from otolith ring counts, which are assumed to be daily growth increments as in other pomacentrids (1, 3).
The impacts on drying behavior of basic density, initial moisture content, percentage and position of heartwood, ring count, rings from the pith, growth ring angle, and earlywood and latewood coverage on board faces were investigated for western hemlock (Tsuga heterophylla) lumber.
In the meantime, Jackson upped his ring count to nine, tying Auerbach's record.
If the two ring counts differed, the section was read again, and if the third ring count differed from the previous two ring counts, the spine was considered unreadable and discarded.
Knot area, ring count, ring angle, initial MC, and heartwood percentage were measured for each board but not included in the final correlation.
On the other hand, the index of completion, being the ratio of the marginal increment to the width of the previous band, would be expected to be constant at the same time of year for a particular species, regardless of the ring count.
I'm the biggest sandpaper snob in the world," Copenheaver says, adding that she sands with finer and finer grade sandpaper, until she winds up with "a polish on the wood you wouldn't believe," making possible a ring count that's "absolutely perfect.
The distribution of species, timber quality, and aesthetically important growth characteristics (ring count, color, consistency of ring count, roundness of bole, etc.
