As a team building exercise the lab went on a kayaking tour of ca 8km on the Werre in Herford, Germany. It was a very beautiful tour and we saw many king fishers, herons and other birds. The pictures speak for themselves!

Four of our lab members presented their work at the Congress of the European Society for Evolutionary Biology (ESEB 2025) in Barcelona in August. Beril presented a pilot study linked to her multi-pinniped comparative genomics project, which looks into differences in genomic inbreeding and bottleneck strength as a consequence of historical sealing across South American fur seal populations. Rebecca presented her recently published study on the effects of mutation load on sexual trait expression and reproductive success in lekking black grouse. Kosmas presented some new results on the distribution of mutation load and inbreeding across different Antarctic fur seal colonies. Finally, Anneke got the opportunity to present results from a joint project led by David about the effects of inbreeding on Antarctic fur seal female reproductive success.
As a bonus, the event coincided with the “Festes de Gràcia”, a street festival in a neighborhood of Barcelona called Gràcia with beautiful street decorations, music and dance. ESEB 2025 joined in by incorporating themes of evolution and biodiversity in the street decorations and other activities. Of course ESEB attendees were welcomed to join in on the festivities, which were great fun!
We had a great conference with many interesting presentations and thought-provoking discussions.










A massive congratulations to Jonas for successfully defending his PhD thesis “Dissecting complex chemical phenotypes in the Antarctic fur seal“! We wish him all the best in his new job!


Last week Anneke successfully defended her PhD titled “Genetic dissection of anthropogenic impacts on a declining Antarctic fur seal population“. Congratulations dr Anneke! 🥳🎓 Luckily we don’t have to say our farewells yet, as Anneke will continue working on her Antarctic fur seal project as a postdoc in the group 🦭


Last week, the Hoffman Lab organised their second lab retreat, hosted in the middle of the serene Teutoburg Forest. We spent two beautiful summer days team-bonding, discussing science and fieldwork, and organising lab improvements.
On the first day, we started by getting to know each other a little bit better by playing a game of “two truths and a lie”. In this game, each group member made three statements about their lives and the others had to guess which one was the lie. Next, we provided feedback to Anneke’s PhD defence which is coming up shortly, followed by a fruitful discussion of equity, diversity and inclusivity in the lab. After a relaxing walk-and-talk in the forest and a lovely dinner at the Brand’s Busch restaurant, we enjoyed the inspiring pictures and stories from Juan about the many field sites he has set up and/or regularly travels to.
On the second day, we played another round of “two truths and a lie”, discussed how to communicate our research findings with the wider public, and drafted a statement about the lab’s values and work culture that will soon be published on our website. We ended the day by openly discussing the supervision experienced by PhD students and postdocs in the lab, highlighting both strengths and points of improvement.
And of course, the retreat provided us with an excellent opportunity to take our annual group picture!

Two of our lab members presented their work at the 36th Annual Conference of the European Cetacean Society in Ponta Delgada, Azores in May 2025. Both presented recent work from their PhD projects on Antarctic fur seals. Petroula presented her work on host-microbiome interactions from birth until weaning, and Ane Liv presented a project using an autonomous fixed camera and a machine learning approach to identify patterns of predator-prey interactions. We thoroughly enjoyed the conference, which featured lots of interesting workshops, inspiring talks and cool discussions!





Etienne and Joe just returned from a short but very successful visit to Spain, where we attended the Mycoforum 2025 living lab mycotour, collected Boletus pinophilus samples for genetic analysis, visited experimental plots and discussed mushroom science! A great time was had by all. We would like to thank our wonderful host and collaborator, Fernando Martínez-Peña!







Some of our members were lucky enough to present their work on the SMM2024 in Perth, Australia! Below an impression of post-doc David, presenting the recent paper that’s in press about Northern elephant seals, Ramona presenting her recent work on polar ocean soundscapes and ecoacoustics, and Ane Liv presenting her poster on trait decomposition in Antarctic fur seals!





Five lab members attended the conservation genomics conference in Paris 2024. We had a great time, saw some very interesting talks and posters, and came home with many new ideas.






We had a very productive and inspirational lab retreat. On the first day, everybody presented current and past work, we had a “walk&talk” to catch up with each other and explore the area, and we ended with a fantastic workshop exploring some topics of interest and future directions (and ended with drinks!). The second day we started with a workshop about strengths and weaknesses, discussed lab organization and ended with the opportunity to sit together one-on-one for mentoring/scientific exchange. And of course there was time for a group picture! Thank you all that helped organizing this retreat!
