ESEB 2025 Symposium: 'The contribution of the microbiome to host adaptation and plasticity' (S07). The ESEB 2025 Congress will be held at the International Convention Centre of Barcelona (CCIB) in Barcelona, Spain, from August 17 to 22,2025. Abstract submission deadline: April 25th 2025 (link below) We are excited to announce an exciting symposium on the role of microbiomes in host adaptation and plasticity and we invite you to submit your abstracts for contributed talks and posters. Organisers are Melissah Rowe (Netherlands Institute of Ecology), Florent Mazel (University of Lausanne, Switzerland), and Klara Wanelik (University of Surrey, UK), on behalf of the ESEB funded STN on Wild Animal Microbiome Evolution (WAME). Contribution of the microbiome to host adaptation and plasticity All organisms host microbial communities in and on their bodies. Over the last 20 years, there has been an explosion in studies characterising the microbial communities associated with a diversity of host sites (e.g. gut, skin, rhizosphere) in a wide range of taxa across the animal and plant kingdoms. Recent studies have shown that these microbiomes can have major impacts on host biology, including effects on digestion, development, immunity, and behaviour. Indeed, it is now widely recognized that microbiomes can play a fundamental role in host ecology and evolution. However, our understanding of the specific role of microbiomes in the evolutionary process by which a host becomes better suited to its environment (i.e. host adaptation) remains relatively limited. Key examples of microbiome-mediated host adaptation are emerging , but the critical next step is to broaden our understanding of the contribution of microbiomes to host adaptation and the role of microbiome-mediated plasticity in this process. Our proposed symposium will bring together a diverse group of researchers working in this rapidly growing and important field. We will showcase work spanning a wide range of host study systems and including a variety of theoretical, experimental, and field approaches. We are pleased to confirm as invited speakers - Dr. Hassan Salem (Max Planck Institute for Biology Tübingen, Germany) and Dr. Carola Petersen (Evolutionary Ecology and Genetics, Zoological Institute of Kiel University, Germany).
