    Reconstructing past xylogenesis of black spruce

    Hemispheric-scale reconstructions of surface temperature fluctuations over the last millennium have identified the 20th century as uniquely warm. Boulouf Lugo et al. monitor timings of wood formation in black spruce, Picea mariana, on a weekly timescale over 9 years in the boreal forest of Quebec, Canada, and use the results in conjunction with temperature records to […] More

    Modelling growth of the cambial surface

    Individual tree growth models traditionally focus on apical growth and architecture; however, cambial growth equally contributes to plant form and function. Sellier et al. present a model of cambial growth based on level sets, a technique used in computational physics. It simulates tree shape and xylem structure resulting from arbitrarily defined growth functions, and can be […] More
