Dear colleagues, We are pleased to announce the third Genomics of Marine Mammals workshop will be held at the World Marine Mammal Conference in Barcelona on Sunday 8th December, 08:30-17:30. Details can be found following this link and a summary of the workshop is given below: https://www.wmmconference.org/workshops/#Genomics%20of%20Marine%20Mammals%20... We have invited several colleagues working at the cutting edge of the field to give talks. We still have space to accommodate additional talks and would be happy to receive abstracts of studies that are at, or near, completion. Email details can be found following the link above. *Workshop Summary: *This will be the third Marine Mammal Genomics Workshop, first held at the 20thBiennial Conference in New Zealand. The last workshop was four years ago in San Francisco and resulted in a published review by workshop presenters (https://doi.org/10.1093/jhered/esw044). Genomics is a dynamic field, and new genomic data, novel techniques and methods of analysis appear monthly. We will bring together researchers in this fast-moving field to discuss new developments in marine mammal genomics including phylogenomics, population genomics, conservation genomics, museomics, proteomics, and hologenomics among others. The symposium will provide a platform to present more complex and detailed results to a more specialised audience than at the main biennial conference. Researchers will present cutting edge research on marine mammals with the aim of describing and summarizing state-of-the-art techniques and methods to workshop attendees. A panel discussion will follow the talks, so attendees and speakers will able to ask questions and interact. Andy Foote and Michael McGowen
