Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.

ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...
