Dear friends and colleagues, As part of the 3rd Joint Congress on Evolutionary Biology 2024 in Montreal, Canada, 26-30 July (https://www.evolutionmeetings.org/), we are organising a symposium on "Advances in marine evolutionary biology" (https://www.evolutionmeetings.org/symposia.html). The goal of the symposium is to bring together evolutionary biologists working in marine systems across the globe and highlight scientific and technological advances in the field (See a more detailed summary below) If you work with evolutionary marine biology we would be very happy if you consider submitting your talk to our session! Talks that are not selected for a symposium will nevertheless be placed in one of the general sessions. Please do not hesitate to contact us if you have any questions: Ellika Faust ellika.faust[at]eawag.ch Pierre De Wit pierre.de_wit[at]bioenv.gu.se Summary: Around 500 million years ago life had not yet colonised land and was exclusively found in the oceans. Despite the rich diversity of life found in our oceans, much has yet to be described and put into an evolutionary context. Practical hurdles of working in the marine environment, as well as the complexity of marine systems, have historically impeded our ability to study them. However, with recent theoretical and technological advancements, these hurdles are diminishing, now allowing for in-detail studies of biological processes such as speciation, local adaptation, connectivity, and genotype-phenotype associations in diverse marine systems. This symposium will broadly feature studies that advance our understanding of these phenomena and their underlying mechanisms. It aims to highlight similarities and interconnections of study systems across different coastlines and oceans, thereby building a base for future collaborations across networks and societies in a world undergoing dramatic change.
