TL;DR: It is argued that a new integrated field of forensic timber identification should be a global investment priority, for which the ongoing collection, curation and taxonomic study of appropriate reference material is a critical part.
Book ChapterDOI
Structure and function of wood
TL;DR: The objective of this chapter is to review the basic biological structure of wood and provide a basis for interpreting its properties in an engineering context to better understand the strengths and limitations it presents as a material.
Journal ArticleDOI
Carbon starvation in glacial trees recovered from the La Brea tar pits, southern California
Joy K. Ward,John Harris,Thure E. Cerling,Alex C. Wiedenhoeft,Michael J. Lott,M. D. Dearing,Joan Brenner Coltrain,James R. Ehleringer +7 more
TL;DR: Evidence that C3 primary productivity was greatly diminished in southern California during the last glacial period is found, found by scaling ancient ci values to plant growth by using modern relationships.
Journal ArticleDOI
