How do pheomelanic birds handle oxidative stress if their pigments consume antioxidants?🤔
Seems like physiological plasticity may be the answer💡🤯

Paper News!🚨

You may be more familiar with #acromelanism than you think🤔The culprit?
A heat-sensitive protein that affects melanin synthesis!

Turns out, it's not much studied in birds🫣

@ATJCagan @Nature UAU! 🤩

@MafaldaSFe has been working on Atlantic herring adaptation. Lovely to hear her explain how SVs have shaped herring populations and how they perfectly distribute over latitudinal gradients in concordance to water temperature🐟🌡

Oh the Danaus sp. dilemma...🙈
Amazing talk by Rishi de-Kayne from @simonhmartin lab on dynamic supergenes conferring different colors morphs to Monarch butterflies 🦋🌈 #SMBE2023 #colsci

Recent private chr fusion in Brenthis butterflies 🦋 shows signs of positive selection BUT in the context of GF it may be a tech artifact.
Sounds very promising and hopefully they can disentangle these effects later on 😊 Beautifully clear talk from Alex Mackintosh👏

Fancy colourful birds?🌈🐦 Interested in sex-specific trait evolution?🧬🕵‍♀️
Come find me and Poster_847 at San Paolo Cloisters #SMBE2023 for exciting cuckoo facts 😉 (pun intended)

Amazing talk from Graduate Student Excellence Awardee Aurora Alvarez-Buylla #SMBE23
Poison frogs use ABG to bind dietary alkaloids avoiding toxicity. Interestingly this blood protein his homologous to CBG, cortisol binding protein in mammals.
Toxicity is still stress right? 🤷‍♀️😋

@cowbirdlab Beautiful! Love tiles🙂

[CristianaMarques @CIMarques2]

@facasaro Is it online streamed?

[CristianaMarques @CIMarques2]

@cowbirdlab Congratulations Mark!
Sending positive vibes your way. They are lucky to have you and I am sure you will do great🤗

[CristianaMarques @CIMarques2]

@BioMarAlvarenga @evomics Boa Sorteeee! 🤗😘

@f_najas Can it be a sensorial organ?
I was wondering if you study coloration on these, too :)

[CristianaMarques @CIMarques2]

@f_najas Uau! Super cool :)
What is the most surprising thing you learned about this species complex?
Sorry for asking I got really curious about their look eheh :)
