Species Identification and Design Value Estimation of Wooden Members in Covered Bridges

Covered timber bridges are historic structures with unique aesthetic value. To preserve this value and maintain bridges in service, robust evaluation of their performance and safety is necessary. The strength of the timber found in covered bridges can vary considerably, not only because of age and condition, but also because of species and grade. For the practicing...

DNA barcode authentication and library development for the wood of six commercial Pterocarpus species: the critical role of xylarium specimens

DNA barcoding has been proposed as a useful tool for forensic wood identification and development of a reliable DNA reference library is an essential first step. Xylaria (wood collections) are potentially enormous data repositories if DNA information could be extracted from wood specimens. In this study, 31 xylarium wood specimens and 8 leaf specimens of six important...

The origins of Tradescant’s ‘India Occidentali’ wooden clubs: ¹⁴C dating, material identification and strontium isotope studies

This paper focuses on the material study (radiocarbon dating, wood identification and strontium isotope analyses) of four large ‘India occidentali’ clubs, part of the founding collections of the Ashmolean Museum, in Oxford, and originally part of John Tradescant’s ‘Ark’,in Lambeth (1656). During the seventeenth century, the term ‘India occidentali/occidentales’...
