Identifying wood holds significance across several domains and is of critical importance for commercial, forensic, archaeological, and paleontological applications. Also, timber identification provides new tools needed for the tracking of illegal logging and transportation. [8] Wood identification is also important from an economic point of ...
It can be grown by itself or in mixed species plantations, and the nitrogen-rich leaves falling to the ground enrich the soil and increase the production of such trees as walnut, Douglas-fir and poplar on poor quality soils. Although the tree can live for up to 160 years, it is best felled for timber at 60 to 70 years before heart rot sets in. [8]
It contains only three species, C. esmeraldense, C. rodiei and C. venenosum, and is native to northern South America. The name Chlorocardium means green heart , referring to the wood. They are trees up to 40 m high, mostly 30 m high, and are hermaphrodites. They are slow-growing canopy evergreen trees and have a valuable timber.
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
There are several databases relating to wood anatomy. One of them, InsideWood, is an online resource and database for wood anatomy, serving as a reference, research, and teaching tool. [13] [14] This database was created by several international researchers, members of the IAWA, mostly botanists, biologists and wood scientists. [15]
To search for unknown risk factors for cardiovascular disease, Hazen and his colleagues designed a multipart study that included an analysis of fasting blood samples from 1,162 patients who had ...
Furthermore, food biodiversity, as measured by the absolute number of biological species in the usual diet, was negatively associated with the total mortality rate and cause-specific deaths due to cancer, heart disease, respiratory disease, and digestive disease among ~450,000 adults from nine European countries.

Calocedrus decurrens is a large tree, typically reaching heights of 30–40 meters (100–130 ft) and a trunk diameter up to 1.2 m (3 ft 11 in). The largest known tree, located in Klamath National Forest, Siskiyou County, California, is 47.98 m (157 ft 5 in) tall with a 12 m (39 ft 4 in) circumference trunk and a 17.5 m (57 + 1 ⁄ 2 ft) spread.
