Dear all, we have moved to BlueSky, connect with us on @thehoffmanlab.bsky.social🦋 The old twitter account will be discontinued. Thank you for following us and we hope to see you on BlueSky!

Some of our lab members visited the Marine Mammal conference in Perth, Oz. They had a great time (and the ones staying at home are very jealous! 😉) #PerthSMM2024 @marinemammalogy

ICYMI, yesterday we reported the major decline of the Antarctic fur seal on Bird Island - a 40% drop in the population since 2009 🦭 Here's population biologist Jaume Forcada to introduce the story ⬇️ Full article and film: ow.ly/C8Sh50PXJOc

on three important early #Antarctic fur seal life traits; pup birth weight, pup survival and pup growth. The findings suggest that #selection may mainly act on the juvenile life stage, rather than early pup life stage. Read more in @SciReports nature.com/articles/s4159…

Check out this paper by one of our PhD candidate @AnnekeTw1tter et al! Using both #SNP data as well as #microsatellites, they found that there was no consistent effect of either individual or maternal #inbreeding 1/2

@BrejonEtienne and colleagues used whole #genomes from 225 samples of Boletus edulis spread across the Northern hemisphere and found that ROHs could reveal the genomic legacies of major #climatic events in this key forest engineer. 2/3

Runs of Homozygosity (#ROHs) are a powerful tool to quantify genomic inbreeding. Yet, they haven't been applied to #fungi... until now! 1/3

These findings question the role of MHC in the chemical encoding of genetic information in the Antarctic fur seal. Paper in #ProceedingsB @RSocPublishing https://royalsocietypublishingorg/doi/10.1098/rspb.2023.2519

... no effects of MHC  relatedness on #chemical similarity of #skin swabs. There was also no relationship between MHC heterozygosity and chemical diversity. 2/3

Check out this paper by colleague @ebbetoj! Jonas et al. explored how an individual's genotype is encoded in #odour. One of the potential pathways could be via the major histocompatibility complex (#MHC). However, they found... 1/3

.@ecopetridish presented her poster on host-microbiome interactions in the Antarctic fur seal!

Ane Liv Berthelsen presented her first preliminary results of her trait decomposition project

Several of our lab members are joining the conservation genomics conference in Paris! 👇
