Our new paper is officially out ! 🎉 We found that iridescence tends to converge between sympatric Morpho butterflies! This signal is likely driven by predation pressures, bringing new evidence to the evasive mimicry hypothesis, i.e. the evolution of confusion patterns in hard-to-catch prey!

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...

Predicting the effect of a #mutation on #fitness is hard. @oliviamghosh.bsky.social @petrovadmitri.bsky.social &co use fitness effects of adaptive yeast mutants to show that underlying genotype-phenotype-fitness maps are low-dimensional but context-dependent @plosbiology.org 🧪 plos.io/4dLy2Ez
Two models for the nature of pleiotropy in adaptation. Left: Schematic of the environmental structure in this study. Environments can be mapped onto a multidimensional environment space characterized by chemical and physical compositions. The large green circle represents an environment where adaptive mutants evolved, and the large pink circle is a distant environment. Around each base, a set of identical environmental perturbations (arrows) is applied, generating clusters of similar environments around distinct base environments. Top right: Schematic of fitnotype map for adaptive mutants near their home base environment. By measuring fitness in each of the green environments, one can infer how many fitnotypes matter for this set of mutants in their home environment. Here, only four of the possible 8 fitnotypes matter. Bottom right: When the mutants are moved to the distant base environment, and their fitness is measured in all pink environments (base and perturbations), there are two possibilities. Either more fitnotypes become important and the space appears higher-dimensional (left, pleiotropic expansion), or the set of fitnotypes that matters remains low-dimensional, but shifts (right, pleiotropic shift).

Come and join our team! A 2-year postdoc position is available in our "Genome Evolution" department at Univ Paris Saclay. We want to play with phylogenetic models accounting for horizontal transfers of transposable elements. Application& details on the official portal: emploi.cnrs.fr/Offres/CDD/U...
Object: Postdoc Position 

Building a phylogenetic model for horizontal transfers of transposable elements 

A postdoctoral position (24 months) is available to work at EGCE (Gif-sur-Yvette, France, CNRS / Université Paris-Saclay) from January 2026. 

Transposable elements (TEs) are repetitive DNA sequences capable of promoting their own mobility. They are widespread across the tree of life and often represent a substantial fraction of eukaryotic genomes. Beyond their ability to invade genomes, TEs are frequently reported to undergo horizontal transfer, enabling their colonization of new hosts. However, understanding and predicting how horizontal transfers shape the distribution of TEs among species is far from straightforward. In particular, estimates of transfer rates based on documented cases are both biased and approximate, since transfers occurring close to speciation events are virtually undetectable. This project aims to develop explicit phylogenetic models of TE evolution that incorporate horizontal transfers, and to use these models to obtain statistical estimates of key evolutionary dynamics of TE families across species (e.g., horizontal transfer and extinction rates). The postdoctoral project will focus on exploring the impact of horizontal transfers on the distribution of TE presence/absence among related species, using statistical and/or computational approaches. Context

The position will be part of a 4-year collaborative project funded by the French National Agency (ANR). The research consortium gathers two departments (from Paris-Saclay university and from Université Lyon 1), and involves 7 Pls and 5 postdocs and PhD students devoted to distinct workpackages of the project. The postdoc will be based at EGCE, which is part of the Institute for Ecology and Evolution (IDEEV). The institute offers an exciting and active scientific life, it is located on the new research campus of Paris-Saclay, 35 km south of Paris.
