📌 Final version of my review paper on the definition of #SexualSelection is out in @BehavEcol.   I discuss potential limitations of a recently advocated definition and propose an alternative one.   1/4   academic.oup.com/beheco/article…

Big news! 🎉 My first PhD chapter has been published in @PLOSBiology, and it just made the cover! 🐦🌍Perfect time to dive into the key findings from our global study on sexual selection in birds. 🧵👇 📖 Read the paper: doi.org/10.1371/journa…

I am loving the @EvolLetters by G. Moggioli. This issue has 3 articles about the Darwin-Bateman paradigm. Lehtonen & Parker doi.org/10.1093/evlett… provide theory, w/ comments by @timjanicke doi.org/10.1093/evlett… and Mokos et al. doi.org/10.1093/evlett…

Final version of this thing now published in @PLOSBiology, so ... some weekend reading. 🧵 Sexual selection (SS) is a major strand of evolutionary theory, but how and why it varies across species at global scales is poorly known. 1/9 journals.plos.org/plosbiology/ar…

Does vegetation structure shape animal vocalisations? A meta-analysis testing for phenotypic and evolutionary responses suggests that the acoustic adaptation hypothesis is not universally valid across birds, amphibians, and mammals.   Kudos to @brbbfreitas for the terrific work!

📌Just published: "Meta-analysis of the acoustic adaptation hypothesis reveals no support for the effect of vegetation structure on acoustic signalling across terrestrial vertebrates" More details 👇 onlinelibrary.wiley.com/doi/10.1111/br…

How and why does #SexualSelection vary geographically? @ra_barber @ja_tobias &co study 10,671 #bird species, revealing that avian sexual selection varies latitudinally, is explained by temperature seasonality & other #climate-related factors #PLOSBiology plos.io/4fixxjC

Super happy with our new collaborative paper in the Neotropics! We examined how climatic variability affects sexual selection for nuptial gifts. Congrats Camila for this awesome research 🙌🏻 and the fantastic work of all authors Find out more at @ASNAmNat journals.uchicago.edu/doi/epdf/10.10…

Fantastic to see this study come to life. Congrats, Lennart!

Experimental study suggests that sperm competition in hermpahroditic flatworms favours individuals that produce sperm of intermediate size: @Santhosh_s96 @TimJanicke & Prof. Dieter Ebert @UniBasel_en ow.ly/g6Jk50T8vOb

Does the inherent sex difference in gamete size drive sex roles? In a recent @EvolLetters opinion piece, @TimJanicke reflects on recent theoretical and empirical advances in understanding how anisogamy shapes sexual differentiation. doi.org/10.1093/evlett…

Delighted to share my thoughts on the latest theoretical and empirical work exploring the evolutionary foundations of sex differences in #SexualSelection. Out now in @EvolLetters.   academic.oup.com/evlett/advance…

Interested in sexual selection in plants? This PhD position might be for you! Please get in touch.

In an attempt to be explicit about the ultimate target of intra-sexual competition, I propose to define sexual selection as competition for access to reproductive resources provided by potential mating partners.   4/4

I argue that the nature of pre-copulatory competition does not depend on whether individuals compete for gametes or any other resources accessed through mates.   Instead, both sexes compete for a package of resources including gametic and non-gametic resources. 3/4

#SexualSelection and #speciation – unpublished data? For a #metaanalysis of comparative studies testing for a relationship between sexual selection and speciation, we are looking for unpublished data or studies with a different focus that might go undetected. Please get in touch!

Many thanks for encouragement and inspiring discussions to @kokkonutter, @JTonnabel, Patrice David and Beatriz Alvarez. Also to Sin-Syue Li for providing his beautiful picture of copulating painted snipes

Not much interested in definitions? Thought I was neither, but a recently proposed definition of #SexualSelection kept me pondering. Happy to share my thoughts (and another alternative definition) in an invited review in @BehavEcol   academic.oup.com/beheco/advance…
