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:
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:
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!
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.
Well, this one is a little bit special. My first sole-author paper has just been accepted for publication at Evolution. The study presents a two-locus model of sexually antagonistic selection for hermaphrodites, and investigates the consequences of genetic linkage, self-fertilization, and dominance for the maintenance of sexually antagonistic genetic variation.

Our methods paper describing how to use our new R package LoLinR to estimate monotonic biological rates using Local Linear Regression has just been accepted at the Journal of Experimental Biology! (see package and reproduce the paper here).

The second of the papers from my Ph.D. was recently accepted at The American Naturalist! Details to come.
