Are you working on biodiversity monitoring using genomics? Are you developing (AI)tools to track molecular change in declining populations? Are you employing novel methods to track molecular change during or after genetic decline? We would be happy to receive your submissions for #SMBE2026!
SMBE2026 Symposium 5 | Molecular evolution in the era of genetic diversity decline

smbe2026.org/programme

Organisers
- Madlen Stange — Leibniz Institute for the Analysis of Biodiversity Change, Germany
- Deborah M Leigh — Senckenberg Nature Research and Goethe University Frankfurt, Germany

Loss of genetic diversity is now recognised as a critical component of the global biodiversity crisis, with direct implications for species’ adaptive potential, population persistence, and long-term evolutionary trajectories. For molecular evolutionists, this represents both an urgent challenge and a unique opportunity: unprecedented genomic resources and analytical methods allow us to quantify genetic erosion, reconstruct historical baselines, and model future outcomes at scales unimaginable a decade ago. We are now able to directly study evolutionary processes in declining, newly formed, or eroded populations, which offer unique insights into the evolutionary past and future. This symposium aims to highlight research at the interface of molecular evolution, population genomics, and biodiversity monitoring. We will showcase cutting-edge genomic methods—ranging from ancient and historical genomics, whole genome-based analyses, and multispecies genomic syntheses, to entirely novel AI and synthetic biology frameworks—that track population-level molecular change over time and space. How these methods have been used to identify evolutionary patterns or changes in the face of loss or restorative action. As well as, how these methods can be used to support transformative change. By bringing together researchers working on evolutionary theory, genomic inference of diversity loss, temporal monitoring of populations, and large-scale data integration, this symposium will provide a forum to identify common conceptual ground, share methodological innovations, and explore the methods needed for future advances.
