I'm resharing in English the very sad news of the passing of French botanist Francis Hallé, specialist of tropical #forests and #tree architecture. You can find more about his life and career (and see some of his amazing drawings) here: www.foretprimaire-francishalle.org/en/who-is-fr...

Lichens (Xanthoria, Physcia and others) on a graffiti paint chip. On lakeside cliffs, Yellowknife, Northwest Territories, Canada. #lichen #fungi #fungifriends #graffiti
Photo of an old, red paint chip partially peeled off cliff rock. The paint chip and surrounding rock in nearly covered in several species of lichens growing in a clump. Lichens are orange, yellow, white and several shades of grey in colour.

Nature Reviews Biodiversity, Published online: 02 January 2026; doi:10.1038/s44358-025-00112-2Experiments manipulating tree species diversity and measuring effects on ecosystem function have been important tools for assessing how biodiverse forests can accumulate biomass, store carbon and help to meet climate goals. This Review summarizes key findings from global tree biodiversity experiments.

Signaling at the interface: The cell wall, peptides, and extracellular vesicles mediate partner communication during arbuscular mycorrhizal symbiosis - ScienceDirect
Signaling at the interface: The cell wall, peptides, and extracellular vesicles mediate partner communication during arbuscular mycorrhizal symbiosis
Arbuscular mycorrhizal (AM) associations of plants and Glomeromycotina soil fungi play a crucial role in all terrestrial ecosystems. In this mutually beneficial interaction, obligate biotrophic fungi acquire photosynthetically fixed carbon from the plant, while the mutualistic fungi enhance plant access to soil nutrients. AM fungi colonize the inner tissues of host roots, where they form specialized symbiotic structures (arbuscules) within fully differentiated cortex cells that are reprogrammed to host the microbe. Given the intimate nature of the interaction, extensive partner communication at the interface of plant and fungal cells is crucial for the development and functioning of AM symbiosis. The peri-arbuscular space, a specialized apoplast compartment surrounding the arbuscules, supports not only nutrient exchange between the symbiotic partners but is also the site of extensive partner crosstalk mediated by cell wall components, receptors, signaling peptides, and extracellular vesicles. Such signaling processes in the apoplast modulate plant immune responses to enable colonization by beneficial fungi, making this compartment a key player for the establishment and maintenance of AM symbiosis. In this review, we discuss recent discoveries related to the role of partner communication in the apoplast, with a focus on peptide and cell wall signaling, as well as extracellular vesicles.

Interested in working on the theory of and concepts behind multiple factor impacts on ecological systems and beyond?

Please send expressions of interest. Starting Jan 2026, I would be awarding up to three postdoctoral fellowships on this topic (12 months; 2,5K €) to drive progress on this topic.
