Modestly, we decided to review a century's worth of theories of balancing selection :) onlinelibrary.wiley.com/doi/10.1111/...

2025 Student Paper Award: Evolution in one sex is often affected by selection acting on the opposite sex. Geeta Arun et al. explore this using fruit flies and find that responses to selection are largely parallel between sexes. Read now ahead of print! www.journals.uchicago.edu/doi/10.1086/...

In a stunning display of coordinated movement, male Swallow-tailed Manakins dance together in groups of up to five to attract females. Researchers studied display consistency, group size effects and implications for female choice: royalsocietypublishing.org/doi/10.1098/... #RSOS #AnimalBehaviour

Does #SexualSelection fuel #Speciation? Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force. doi.org/10.1093/evle...

📜 Why are trade-offs often so elusive? Does the distribution of resources in a population affect if life history trade-offs emerge? We tested this experimentally in the Australian field cricket using a re-sampling approach. Now out #OpenAccess in @journal-evo.bsky.social: doi.org/10.1093/evol...

We’re offering a fully funded 4 yr PhD position to work on Sexual selection in complex environments at the @uv.es. Co-supervised by @dbergerbiol.bsky.social. Find details below 👇

Many of us are using LLMs in coding and scientific writing. They are very helpful tools, but we need to be thoughtful as we integrate them into our work flows to preserve accountability, voice and trust. academic.oup.com/evlett/advan.... An editorial at @evolletters.bsky.social for discussion:

How to interpret sexual selection using Bateman gradients? When are these not informative & how should researchers identify, deal with confounded gradients? We simulate anisogamy & sperm competition to provide a guide for using Bateman gradients. Out in Evolution academic.oup.com/evolut/advan...

Looking for a PhD project on sexual selection? Join us at UZH! Application deadline: 9 June 2025. jobs.uzh.ch/job-vacancie...

Finally out: Predicting adaptation to climate warming www.nature.com/articles/s41... We find that there are many genomic routes to heat-adaptation, but this can also make genomic data of limited value for prediction. A tour de force by @denovorego.bsky.social , with @stelkens.bsky.social.

New work from our lab, led by @avigayillev.bsky.social! Male mate choice for large females is typically attributed to the higher fecundity of those females. However, we show that in #Drosophila, large females also produce daughters with higher fecundity. doi.org/10.1093/evol...

The call for MSCA fellowships is soon opening! This is a great postdoc program, so do get in touch if you'd like to join our group from another country, within or outside Europe. The University of Montpellier and CNRS can train you on writing your proposal! forms.office.com/Pages/Respon...
