Common Name (s): Araucaria, pine (tropical) Distribution: Primarily tropical regions in the Southern Hemisphere. Genus Size: Approximately 20 species (many of which are endemic to the island of New Caledonia) Mechanical Characteristics: Generally moderate density with good strength characteristics for a softwood.
Shooting involved spearing the logs down the slope along a brushed path or track. The front ends of the logs were pointed to make their travel easier. ‘Chuting’ involved the sending of logs in a specially made chute constructed out of timber or bark; in …

Some of the largest logs in this arid desert region are ten feet in diameter, the remnants of trees that were over 200 feet tall. Seed cones of Araucaria mirabilis from this site are remarkably preserved in every detail.
Araucariaceae - Wikipedia
Araucariaceae is a family of conifers with three living genera, Araucaria in the Araucarioid clade and Agathis, and Wollemia in the Agathioid clade. While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of Agathis in Malesia , it was formerly widespread in the Northern Hemisphere ...

2022年5月1日 · The tree is Agathoxylon hoodii (Araucariaceae), one of the largest individuals in a monospecific forest, whose trunk was infected and decayed by white rot while the tree was alive during the Jurassic. Fungal formation of voids in the wood facilitated the boring of large-diameter galleries by an insect, likely a beetle.

Many of the petrified logs have been assigned to the genus Araucarioxylon, a presumed distant relative of Araucaria; however, new evidence indicates that these petrified logs represent a broad diversity of conifer species. Streams carried dead logs into this once swampy lowland region where they were buried in sediments rich in volcanic ash.
araucariaceous logs in Utah, USA, by applying these three models. Key words: Agathoxylon, fossil forest, fossil log, height–dia-meter growth model, Upper Jurassic, Morrison Formation. FORESTS have played a dominant role in terrestrial eco-systems on earth for more than 300 million years (Berry & Marshall 2015). Some of the most informative ...
Respiration of downed logs in four natural evergreen broad …
2014年8月10日 · The objectives of this study were (1) to quantify the respiration rates of downed logs (R log) and Q 10 of different tree species at various stages of decay, (2) to assess the effect of microclimatic (log temperature and moisture) variables on R log and (3) to estimate annual C flux of the CWD logs in four natural evergreen broad-leaved forest ...
