New meta-analysis out on the role of sexual selection in speciation!

Across the Animal kingdom, we found that stronger sexual selection is significantly (though weakly) associated with greater species richness in comparative studies — suggesting a modest role for sexual selection in speciation.

A great collaboration with Tim Janicke, Jeanne Tonnabel, Tamra Mendelson & Mike Ritchie.

Ornamental traits play a central role in sexual selection. Gussone et al. identify sources of phenotypic variation in ornamental traits by showing that inbreeding and genetic relatedness of rivals affect the dynamic colour-expression in competing males in a cichlid fish.

Januario et al. found no correlation between sexual selection intensity & speciation rates or proxy traits. Because sexual selection intensity has high intraspecific variation and low phylogenetic signal, its macroevolutionary impacts are weak. Read now!

How does sexual selection influence behavioural consistency? Using experimental evolution, Brand et al. demonstrate that evolution under heightened sexual selection limits individual phenotypic plasticity and promotes male behavioural consistency.

New #pterosaur species from #Solnhofen described by Dave Hone and coworkers. Got a big crest so more palaeo #SexualSelection going on. Figure 12 is especially splendid.

#introduction I’m Anne, Professor in #neuroscience at Fribourg University. In our #Drosophila lab, we work on neuronal circuits for reproductive behavior and acoustic communication, sex differences of the nervous system and the signaling function of seminal fluid. I like #arthopods #sexualselection #matechoice #spermcompetition #microscopy and #connectomics
Used to work with #zebrafish #development #axonguidance
Also teaching and keen on #embryology and #histology for medical students...

#introduction
👋 :mastodon:,
I'm a researcher at #INRAE-Nouzilly (France) studying #quantitativegenetics of #chicken #behaviour (especially #socialbehavior) to improve #animalwelfare

I tackle these questions using my background from #EvolutionaryBiology. I've investigated how #sexualselection and #genetic constraints (#pleiotropy, between life stages & sexes) can drive the #evolution of phenotypes & behaviours in red #junglefowl and #drosophila (some cool stuffs to be published soon!)

Bright colors in the animal kingdom: Why some use them to impress and others to intimidate https://news.arizona.edu/story/bright-colors-animal-kingdom-why-some-use-them-impress-and-others-intimidate

Paper: Why are #animals conspicuously colored? #Evolution of sexual versus warning signals in land #vertebrates https://onlinelibrary.wiley.com/doi/10.1111/evo.14636

Species that use their bright colors for #SexualSelection were found to be descended from ancestors active during the day. Conversely, those that use #aposematism — warning that species are toxic — have had ancestors that were active at night.

Introduction: I am an evolutionary ecologist working on (among other things) how mating systems affect #adaptation to changing environments. I like #beetles, #sexualselection, #savanna and #tropicalforest environments and #rstats and am trying to use #julialang with some variance in success. I also #scuba dive using a #jjccr #rebreather, enjoy #triathlon and do mediocre #wildlifephotography. I am moving to the University of Hull in December 2022.
