Just saw this very nice perspective on Tim’s and my paper about expected distributions of autosomal inversion lengths under different selection scenarios by Dr. Andrius Dagilis, to appear in Molecular Ecology alongside our paper. Very cool (not that we are biased)!
This was a special one 🥳 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!

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!

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.

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

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

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.

Well, this post is pretty late, considering the Special Topics Network happened almost a year ago! But, anyway… last July, 2017, I was fortunate enough to attend the ESEB Special Topics Network: ‘Linking local adaptation with the evolution of sex differences’, held at Lund University, Sweden. I got to meet and get to know a lot of really wonderful colleagues around the world during a really stimulating, and rather whirlwind week of geekery. One of the concrete outcomes of the Network was the decision to try and put together a Special Issue for The Philosophical Transactions of the Royal Society B using collaborations among the attendees as a core for the issue. I was involved in two groups. The first focused on developing new population genetic theory for the evolution of autosomal and X-linked chromosomal inversions during the process of adaptation. The most impressive part of the whole experience for me has been how well the group has worked together and succeeded in developing a really cool study which we recently submitted for review. While there, I also felt I had to be the standard bearer for the poor, underrepresented hermaphrodites, and so I spearheaded another project looking at the consequences of spatially variable sex-specific selection, and local adaptation in species without separate sexes. Keep an eye out for the upcoming Special Issue, in which both of these studies will be published, hopefully sometime in the later half of 2018.
