Applying CLSM to increment core surfaces for histometric analyses: A novel advance in quantitative wood anatomy [PDF]

Dendrochronologia, 2013
A novel procedure has been developed to conduct cell structure measurements on increment core samples of conifers. The procedure combines readily available hardware and software equipment. The essential part of the procedure is the application of a confocal laser scanning microscope (CLSM) which captures images directly from increment cores surfaced ...

Montane forest tree species have lower hydraulic efficiency and vulnerability than lowland forest species in the Atlantic Forest [PDF]

Rodriguésia
The adaptations of plants to different environments are closely related to their wood anatomical traits. This study investigated the wood anatomy of a montane forest community and compared it with anatomical data from three other areas in the Atlantic ...

Wood identification of Dalbergia nigra (CITES Appendix I) using quantitative wood anatomy, principal components analysis and naive Bayes classification [PDF]

Annals of Botany, 2009
Dalbergia nigra is one of the most valuable timber species of its genus, having been traded for over 300 years. Due to over-exploitation it is facing extinction and trade has been banned under CITES Appendix I since 1992. Current methods, primarily comparative wood anatomy, are inadequate for conclusive species identification. This study aims to find a

ECOLOGICAL WOOD ANATOMY OF Blepharocalyx salicifolius (H. B. K.) Berg

Ciência Florestal, 2010
The purpose of this work is the comparison of the wood anatomy of Blepharocalyx salicifolius (H. B. K.) Berg (Myrtaceae) from two provenances in the State of Rio Grande do Sul. There were collected 6 samples of wood; three from “Serra do Sudeste” and the

Machine Learning Models with Quantitative Wood Anatomy Data Can Discriminate between Swietenia macrophylla and Swietenia mahagoni [PDF]

Forests, 2019
Illegal logging and associated trade aggravate the over-exploitation of Swietenia species, of which S. macrophylla King, S. mahagoni (L.) Jacq, and S. humilis Zucc. have been listed in Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix Ⅱ.

Can quantitative wood anatomy data coupled with machine learning analysis discriminate CITES species from their look-alikes?

Wood Science and Technology, 2022
Due to increasing global trade of timber commodities and illegal logging activities, wood species listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) appendices are facing extinction, and their international trade has been banned or is under supervision.

Functional Relationships of Wood Anatomical Traits in Norway Spruce

Frontiers in Plant Science, 2020
The quantitative assessment of wood anatomical traits offers important insights into those factors that shape tree growth. While it is known that conduit diameter, cell wall thickness, and wood density vary substantially between and within species, the ...
