Students were able to benefit from Prof. Skibinski's boundless knowledge. We discussed sex determination and sex ratio for hours. Can you believe we still don't know how sex determation works in #MusselsAreCool?

Didn't you miss hearing from #MusselsAreCool just a little bit? We had our AMMR2026 conference organised by Pierre de Wit at the Tjarno Marine Lab @cemeb.bsky.social, and it was a lot of fun. www.gu.se/en/event/int...

I find this new discovery of a transmissible cancer in catfish fascinating. As it’s described as the fourth example of contagious cancer, let me share this phylogenetic tree of species infected by such rarities.

This one is another oyster species (Magallana gigas) and Chr 2, 5, 8 and 9 seems different from the others the same way as >5 and <5 in O. edulis.

Does anyone here know about Hi-C heatmaps? What do you think of this one? I feel like the patterns of the first and last five chromosomes are different. Would you agree? What do you think that is? Asking for a friend.

Arrived at Roscoff in Brittany for the conference Jacques Monod on #speciation. What a view ! Do we have a hashtag? #cjm25? First plenary lecture was tonight on our (in)hability to predict diversification rates from microevolutionary processes.

Scanning mussel morphology #MusselsAreCool. The attempts are not yet conclusive, but it's cool.

It's been a while since I shared a photo of a burl, that anarchic cellular development that looks like a plant tumour. This one is on the Lez riverbank in Montpellier.

What if the artificial reef concept was transposed on land?

We strongly recommend incorporating @kamilsjaron.bsky.social's k-mer pair coverage method, #Smudgeplot, into your routine.

#PopGen New preprint of the team on the discovery of a very high rate of polymorphic duplication in a marine bivalve. Imagine looking at the distribution of the allelic coverage fraction at heterozygous calls in an indivdual and getting this distribution 👇 😱😱😱

Just to be clear, for a theorician, hybrid fitness reduction due to alternative deletion (or silencing or subfunctionalization) of a copy of duplicated genes, is nothing else, and indeed exactly, a Dobzhansky–Muller incompatibility (nothing new under the sun)

The year 2025 is off to a flying start as I'm already fishing for mussels in the murky waters of ports.

What cooler way to get to work than on a Citycat boat bus on Brisbane's river? University of Queensland students and staff are so lucky.
In this photo you have a motorized catamaran bus that takes you to the University of Queensland on the Brisbane River.

Like every year, I'm posting a photo of my favourite Christmas tree, this magnificent twisted beech tree my family calls Darwin.
