New paper out in The American Naturalist

This was a special one ūü•≥ It all started in Montpellier 2019 at a meeting of the ESEB Special Topics Network “Linking sex differences in selection with local adaptation” when I listened to my now good friend and colleague Dr. Lotte de Vries give an awesome talk about her Ph.D. thesis research on evolutionary demographic models. 3 years, 2 postdocs, 1 pandemic, and many Zoom meetings later, I am very happy and proud to say that the frenzied geek-out we had after that talk was the beginning of an awesome collaboration which has now resulted in an outstanding paper in The American Naturalist (not that I’m biased). I really do hope this is the first of many!

New Paper out at Evolution!

Another one that took a long time to come to fruition, but it’s finally out… Very happy to announce this recent paper with my colleagues here at the Genetics of Sex Differences Research Group at Lund University. This was a great instance of a paper being born the way they ought to be: from discussions started during a lab journal club meeting! Congrats everyone!

New Paper out at Mol. Ecol.!

It was a long time in the making, but well worth it. Happy to post a recent paper with my good friend, colleague, and mentor Tim Connallon on the Distribution of Chromosomal Inversion Lengths under different selection scenarios.

New Paper out at PNAS!

Congrats again to my friend and coauthor Dr. Katrine Lund-Hansen on the publication of one of her main PhD chapters, which has recently been published at PNAS:

Katrine K. Lund-Hansen, Colin Olito, Edward H. Morrow, Jessica K. Abbott. Sexually antagonistic coevolution between the sex chromosomes of Drosophila melanogaster. doi: https://doi.org/10.1101/818146.

Was a very fun project to be involved in. Very cool combination of experimental evolution and theory!

New STN paper!

Congratulations to my wonderful colleagues and coauthors on our recent review article:

Ruzicka, F., Dutoit, L., Czuppon, P., Jordan, C.Y., Li,X, Olito, C., Runemark, A., Svensson, E.I., Yazdi, H.P., Connallon, T. (2020). The search for sexually antagonistic genes: Practical insights from studies of local adaptation and statistical genomics. Evolution Letters. doi: 10.1002/evl3.192

This represents another great contribution by the ESEB Special Topics Network “Linking local adaptation with sex-differences in selection”. Great work everybody!

Correction (!)

Shortly after our paper “Sexually antagonistic variation and the evolution of dimorphic sexual systems” was published at The American Naturalist, I noticed a mistake in our derivation of a few of the results pertaining the invasion of sexually antagonistic alleles linked to a unisexual sterility allele. The correction is now published as:

Olito, C. & T. Connallon. 2019. Correction. American Naturalist 194: 741-742. doi: 10.1086/705014.

New Paper!

Very happy to report that our new paper ‘Sexually antagonistic variation and the evolution of dimorphic sexual systems’ has been accepted for publication at The American Naturalist. This was definitely the ‘queen chapter’ from my Ph.D. thesis, and I am very pleased with out it turned out. Hopefully it will be of interest to a broad cross-section of evolutionary biologists — from floral evolutionary ecologists, to population geneticists studying the evolution of sex chromosomes.

The Phil Trans Theme issue is out!

Well done to all the participants from the ESEB special network ‘Linking local adaptation and the evolution of sex-differences’. The theme issue of Philosophical Transactions is online now at http://rstb.royalsocietypublishing.org/content/373/1757. That was definitely a successful Special Topics Network!

I was involved in two papers from the issue:

Olito, C., J.K. Abbott, C.Y. Jordan. 2018. Linking sex-specific selection and local adaptation in species without separate sexes. Phil. Trans. Roy. Soc. B. (doi: 10.1098/rstb.2017.0426) PDF.
