The first paper from my PhD is now out in the world 🌲📖 Modelling forest dynamics using IPMs and repeat lidar doi.org/10.1002/rse2...

Pipeline for integrating lidar data with structured demographic models for ecological inference. (a) Forest populations are surveyed at appropriate time intervals with a lidar scanner to produce high-resolution 3D point clouds. Point clouds are processed into canopy height models (CHMs) and digital terrain models (DTMs). (b) Individual tree segmentation is performed using a CHM-based algorithm (e.g. Dalponte & Coomes, 2016). (c) Relevant environmental variables are derived. For example, TWI is an indicator of soil moisture accumulation (Kopecký et al., 2021) and is calculated from the DTM. Local competition is inferred from the canopy density surrounding each tree, using the CHM. (d) Trees are matched across time points using a crown-matching algorithm (Battison et al., 2024; Olsoy et al., 2024), before measuring changes in size and classifying mortalities. (e) Continuous traits (e.g. height and crown area) are evaluated for their ability to predict survival and growth across the life cycle. (f) Selected traits and environmental parameters are used to model the vital rates using regressions. (g) The integral projection model (IPM) is constructed based on the selected vital rate models and key life history traits (e.g. mean life expectancy, longevity, generation time) are calculated. (h) Finally, IPM outputs are analysed to test ecological hypotheses.

Foundations and future directions for causal inference in ecological research, forthcoming w/ @katherinesiegel.bsky.social: tinyurl.com/4mm57zzd. We wrote it based on our experience teaching causal inference to ecologists w/ some stuff we wish other papers had reviewed to share w/ the students 1/n

New study led by Ana Elizabeth Bonato Asato published in @journalofecology.bsky.social 🌱🪱 Plant diversity increases above- and below-ground ecosystem functioning and their phenological synchrony, but effects on traits vary across seasons. doi.org/10.1111/1365...

Seasonal shifts in plant diversity effects on above‐ground–below‐ground phenological synchrony

Plant diversity modulates above-ground–below-ground interdependence through intricate phenological dynamics, with the degree of synchrony fluctuating in response to the varying combination of process....

#oneforjournalclub Woody growth of coarse roots of deciduous trees continues throughout the winter! www.nature.com/articles/s41...

No winter halt in below-ground wood growth of four angiosperm deciduous tree species - Nature Ecology & Evolution

As wood growth in deciduous tree stems halts during winter, it has been assumed that wood growth in coarse roots follows the same pattern. This study on the growth of stem and coarse roots of four Eur...
