***Note the extended deadline for registration and abstract submission*** Dear all, Join us at the Linnean Society in London for a hybrid (in-person and online) one-day symposium focused on the mechanisms and consequences of variation in organismal resilience. The mechanisms that allow organisms to both buffer system function from perturbation, and dynamically respond to change are the foundation of organismal resilience. Understanding these mechanisms and how they evolve is one the most pressing challenges in modern biology. Meeting this challenge will require perspectives that span all levels of biological organization, from genes to populations to ecosystems, and collaboration and integration across many different biological disciplines. Organisms are the nexus that unites lower-level genetic, cellular, and physiological processes that underlie resilience to concepts of resilience at the population, community, and ecosystem levels. Why are some individuals and taxa more resilient than others? And how does individual and species-level variation in resilience relate to the resilience of populations, communities, and entire ecosystems? This symposium will address these and related questions to advance our understanding of organismal resilience, and its potential to buffer organisms from environmental change. This is a hybrid day meeting, offering the option of both in-person tickets or online attendance. Confirmed speakers: Patricia Schulte (University of British Columbia, Canada) Christopher Wheat (Stockholm University, Sweden) Rose Thorogood (University of Helsinki, Finland) Luis-Miguel Chevin (Centre d'Ecologie Fonctionnelle et Evolutive, CNRS Montpellier, France) Maren Vitousek (Cornell University, USA) Shane Campbell-Staton (Princeton University, USA) Glenn Yannic (Université Savoie Mont Blanc & Laboratoire d'Ecologie Alpine, France) Chloe Haberkorn (Stockholm University, Sweden) We will host a poster session, and short talks (~15 minutes) will also be selected from submitted abstracts, with an emphasis on early-career researchers. These short talks can be presented remotely for online attendees. If you would like to contribute a poster or submit an abstract for consideration for a short talk, please submit a title and abstract (max 200 words), with lead author affiliation and career stage, to evojlinnsoc@linnean.org by 17.00 (BST) Tuesday 30 September 2025. Date: 20 November 2025 Venue: Linnean Society of London, Piccadilly London W1J 0BF, United Kingdom Registration and abstract submission deadline: 30 September 2025 Further details and registration information can be found here: https://members.linnean.org/events/6862a9bfe5e1810008367c26/description General questions can be directed to Zac Cheviron (zac.cheviron@umt.edu).
