La présence de certains de ces gènes pourrait résulter du transport atmosphérique de bactéries résistantes à des antibiotiques utilisés en médecine et en agriculture par Jean Hamman. Un petit article de vulgarisation sur l'étude de Alonso García et al. 2025. L'importance des microorganismes résistants aux antibiotiques a récemment été soulignée. https://nouvelles.ulaval.ca/2025/10/17/des-genes-de-resistance-aux-antibiotiques-sur-des-lichens-boreaux-du-quebec-6f8e2524-7f13-497f-b9fb-7519...

I had an exciting year of study and research (AER in French or sabbatical). I spent time in Lille with Christelle Fraïsse learning about population genomics and then, some time in Toulouse working with Pierre-Marc Delaux on the genomic interactions between hornworts/cyanobacteria/mycorrhizal fungi. Yes, we are back to hornworts! I also travelled to Leiden to visit leading experts on cycad biology and metabolomics, Angélica Cibrián-Jaramillo (Naturalis) and Francisco "Paco" Barona-Gómez (U. of Le...

Un petit article sur l'importance des anthocérotes dans le magasin pour la science par Isabelle Bellin. Voilà profitez ! https://www.pourlascience.fr/sd/biologie-vegetale/une-piste-pour-ameliorer-la-photosynthese-des-plantes-agricoles-grace-aux-anthocerotes-27463.php et le pdf Pourlascience

We began a fruitful collaboration with cycad experts that got together in the Madrid Botanical Congress (2024). Soon after we submitted a review on the chemical ecology of cycad symbiosis. We provide a new perspective on different aspects of cycad symbioses and the way forward. In our lab we work on the coralloid root /bacterial symbiosis and the leaf endophytes using metabarcoding, metagenomics and metabolomics approaches. Hope you enjoy the review. Abstracts in both English and Spanish ...

In February, I spent my second field season in the Tierras Collectives Emberá, where we have our permanent plot: Bacurú Drõa. The project started in 2021 by the internationally recognized climate scientist Catherine Potvin, now emeritus professor at McGill university. I joined the scientific leadership of the project in 2023 with the tropical biologist Dr. Daisy Dent (ETH Zurich), the social scientist Joseph Levitan (McGill University) and Javier Mateo-Vega(Assistant Under Secretary for Research...

Back in Panamá, I started working on hornworts during my bachelor's degree and, frankly, there were just 5-6 people interested in the world. In 2003, I had the opportunity to do my master's with the hornwort expert, Karen Renzaglia at Southern Illinois University. During my doctoral degree at UCONN, with Bernard Goffinet, I explored phylogenetics and population genetics of one species with separate sexes and potentially lacking any kind of sexual reproduction. In 2012, during my postdoc with...

« Après six ans et demi au laboratoire de Juan Carlos Villarreal, à l’Institut de biologie intégrative et des systèmes (IBIS), il est temps pour moi de tourner une nouvelle page. Je commence un poste de professeure au département de biologie végétale de l’Universidad de Murcia, en Espagne, un retour aux sources pour moi. Je suis arrivée au labo de Juan Carlos en mai 2018 pour un projet postdoctoral de deux ans… Je pense qu’une telle prolongation témoigne que je me suis senti très bien au sein ...

Cette semaine, Philip Bell-Doyon, un étudiant doctoral de notre labo present son séminaire de doctorat intitulé : "Diversité biologique et chimique associée aux écosystèmes forestiers boréaux intacts". La recherche de Philip porte sur la caractérisation de la diversité biologique et chimique associée aux écosystèmes forestiers boréaux intacts. Philip étudie en detail les communautés de lichens, de bryophytes et de microorganismes du sol (bactéries et champignons) entre des vieilles sapini...

Dennis Escolástico-Ortiz successfully defended his doctoral thesis on the population genomics, genotype/microbiome interaction and functional diversity of the bacteria  associated with the moss Racomitrium lanuginosum.  Dennis started a postdoc at Natural Resources Canada. We hope the best for Dennis ! Our lab has three new members. For the summer, we have the visit of Ève Gaubert from Université des Sciences et Technologies de Bordeaux (France). Eve will spend a month in the lab worki...

The Chocó-Darién region is one of the 25 global biodiversity hotspots.  Our lab was invited to do fieldwork in a remote area in Río Balsas, Darién. The project, spearheaded by Dr. Catherine Potvin (Mcgill University), aims at documenting this important biodiversity hotspot while sharing and exchanging knowledge with local Emberá communities. Dr. Potvin's team has established a long-term 15-ha plot in an old growth forest with trees of over 60 meters. With Adriel Sierra Pinilla we traveled...
