New paper by Wout Cherlet & @qforestlab.bsky.social team led by @kimcalders.bsky.social, comparing tree extraction methods from TLS data. TL;DR it's hard to automate, ecosystem dependent & parametric approaches currently outperform DL www.sciencedirect.com/science/arti...

The most well-know use-case of optical fibres is internet.
We show that it actually allows us to measure microclimate temperatures at the ultra-high resolution of 25 cm! Since these fibres can be very long, up to 30 km (!), this novel means of environmental monitoring seems super promising.
Our new perspective on what TLS can (& can't) do in forest research www.nature.com/articles/s41... - led by Eduardo Maeda w lots of great colleagues including @kimcalders.bsky.social @emilyrlines.bsky.social @louiseterryn.bsky.social @benjaminbrede.bsky.social (apols for any I don;t have @ for)

I like big trees and I cannot lie. Great bit of work by @kimcalders.bsky.social @louiseterryn.bsky.social and colleagues using innovative climbing and scanning approach. Stunning illustration of tree structural and biodiversity complexity zslpublications.onlinelibrary.wiley.com/doi/full/10....

This image features part of Bolivia. This vibrant image was created using the radar instrument’s different polarisation channels, with each colour revealing distinct characteristics of the landscape. For instance, green hues mainly represent rainforest, red hues forested floodplains and wetlands, and blue–purple is indicative of grasslands, while black areas are rivers and lakes. The image spans approximately 90 km along the Biomass satellite's flight path (length) and 60 km across in width, with north oriented to the right.
🆕 The first stunning images from our groundbreaking #Biomass satellite mission have been released – they mark a major leap forward in our ability to understand how Earth’s forests are changing and exactly how they contribute to the global carbon cycle 🌳🌍

Ring 2 of the EucFACE experiment, May 2025. Trees have finally returned to good health after a string of extreme events
PhD students Wout and Zane from University of Ghent with TLS scanner at EucFACE
The #EucFACE canopy has finally recovered from the 19-20 drought and the 21-22 floods. Beautiful time for new Lidar scans! @westsyduhie.bsky.social @kimcalders.bsky.social

@qforestlab.bsky.social There are so many leaf-wood separation algorithms, don't know how to choose?
Our latest work (from @qforestlab.bsky.social ) has addressed this issue by providing a robust evaluation framework. Interested? please check our paper: authors.elsevier.com/a/1kKNW7qzT3...
The TFE has been running since 2001. With the roof being taken off now, it becomes a recovery experiment. In collaboration with the University of Edinburgh (UK) and The Universidade Federal de Para & Museu Paraense Emilio Goeldi (Brazil). [2/2]

Important finding for impact modelers by @kornhuber.bsky.social et al.: Climatic extremes change faster/ more severely than anticipated by climate models. The consequences anticipated with impact models (based on climate model-driven forcings) might thus be conservative. www.pnas.org/doi/10.1073/...

It was great having Maurice Leponce give a guest lecture in our BSc course on Ecology, covering Tropical forest biodiversity: large-scale inventories, canopy access, and the role of natural history museums.
Great inspiration for our students!
