Fantastic day in the Amance Arboretum, sampling #pine needles with #DothistromaNeedleBlight symptoms with @kathrinblumenstein.bsky.social and Yasin Korkmaz from @uni-freiburg.de on many Asian, European and American pine species.

Urban trees are under pressure, but we still know too little about the #pathogens affecting them. This study of Yasin Korkmaz and me is about #Diplodia species and their emerging role in stem cankers of deciduous trees in #urban environments. @uni-freiburg.de link.springer.com/article/10.1...

Our Cluster of Excellence FutureForest got funded! Seven years of research on complex social-ecological systems ahead! Stay tuned! 🌲🌳🧍🧍‍♂️🌳🌲 @uni-freiburg.de @dfg.de

#IUFRO25CH Congratulations to Yasin Korkmaz from @kathrinblumenstein.bsky.social’s lab on his best poster presentation award 👏👏👏

#IUFRO25CH Blessing Durodola (@kathrinblumenstein.bsky.social’s lab) is investigating #mycobiome dynamics in symptomatic and asymptomatic giant #sequoias

🎉Ab 1. Januar 2026 fördert die @dfg.de (#DFG) zwei #Exzellenzcluster der #UniFreiburg. Der bisherige #Exzellenzcluster @cibss.bsky.social wird weitere sieben Jahre fortgesetzt. Zudem startet der neue Exzellenzcluster #FutureForests. ufr.link/exzellenzclu...

Yasin Korkmaz's, Marta Belka's and my new paper explores how overlooked animal vectors spread fungal pathogens in forests. These "cryptic vectors" play a bigger role than we think, especially as climate change shifts species distributions. rdcu.be/edIXl #ForestHealth #FungalEcology #ClimateChange

Wie kranke Bäume den Weg zu resilienteren Wäldern aufzeigen: #Baumpathologin @kathrinblumenstein.bsky.social erforscht #Mikroorganismen, die Bäume unter unterschiedlichen klimatischen Verhältnissen schwächen und so den Stoffkreislauf im #Wald stören. Das ganze Video: ufr.link/baumpathologie-video

Shoutout to all the amazing women in our COST Action! Special thanks to our Chair Prof. Johanna Witzell and WG leaders Dr. Mariella Marzano, Dr. Diana Marciulyniene, Dr. Dijana Vuletic, and Prof. Kathrin Blumenstein for their inspiring contribution. #WomenInScience @costprogramme.bsky.social

COST Action UB3Guard event in Novi Sad International experts & stakeholders gathered to develop inclusive decision support tools for urban tree management. Big thanks to Dr. Milica Zlatković, Dr. Lazar Pavlović & their team and to our amazing Chair Prof. Johanna Witzell @costprogramme.bsky.social

STSM Report of the Week This study develops a LAMP assay for detecting Cryptostroma corticale, a major pathogen affecting sycamore maple trees. This rapid diagnostic tool improves forest health monitoring and biosecurity. #Biosecurity @costprogramme.bsky.social @mireiagoga.bsky.social

STSM Report of the Week 🌿 Virulence genes of Diplodia sapinea triggered by abiotic stress using RNA-seq and DGE analyses. New mycoviruses were identified froM RNA-seq data, adding fresh insights into the pathogen's world. @costprogramme.bsky.social @eterhone.bsky.social @needleblight.bsky.social

STSM Report of the Week🌿 This study compiles available & emerging technologies for detecting & managing invasive pests, highlighting innovative tools to boost biosecurity and protect forest and urban ecosystems. @costprogramme.bsky.social #STSM #InvasivePests #Biosecurity #PestManagement

Special and beautiful formation of 'Hair ice' on deadwood caused by the Basidiomycete Exidiopsis effusa. Here in the Black Forest in southern Germany. #mycology #nature #fungaldiversity #Schwarzwald #fungi

STSM Report of the Week 🌿 This study examines the isolation of Phytophthora spp., major forest pathogens, and their biological control using essential oils and metabolites. #STSM #Phytophthora #ForestHealth #Biocontrol #BioSecurity #UrbanForestry #CityTrees

Collaborative Approaches to Urban Tree Biosecurity: Stakeholders’ Perceptions, Actions & Social Networks This study, led by Alessandro Paletto and with contributions from Urban Tree Guard COST Action members, explores collaboration in urban tree biosecurity. www.sciencedirect.com/science/arti...

What a diversity of saprotrophic fungi have been fighting for their realms in this felled beech tree while it had still been alive - all hidden from our eyes #fungi #biodiversity

Check out how Diplodia sapinea emerge in Finland! Funded by Alfred Kordelin Foundation #suuretkulttuurihankkeet & @LukeFinland We used citizen science to gather samples! My favourite pathogen 😅 doi.org/10.1016/j.fg...
