New preprint by the group I am doing my PhD in: “Chromosomal plasticity can drive rapid adaptation in bacteria”.

This is the first chapter of Ever Vega-Cabrera's thesis and has been in the works for a long time.

Chromosomal plasticity can drive rapid adaptation in bacteria

Understanding the molecular mechanisms underlying rapid adaptation to stress is a fundamental question in evolutionary biology.

I've just been reminded of this masterwork book cover. I hope someday my work is cool enough to merit something even half as weird. #Science #ScientificIllustration #Genomics #EvolutionaryBiology

"In light of this development, there has clearly been a paradigm shift away from the sexual stereotypes dominating the early era of sexual selection research towards a more nuanced viewpoint acknowledging that females can be subject to sexual selection too. This progress was substantially fostered by the rise of molecular paternity analyses in the early 1990s revealing that females of many putatively monogamous species are actually polyandrous [25]—also called the “polyandry revolution” [26], which spurred the quest for understanding the adaptive significance of multiple mating from a female perspective."

Sexual selection in females and the evolution of polyandry

Over the last decades, the field of sexual selection underwent a paradigm shift from sexual-stereotype thinking of “eager” males and “coy” females towards a more nuanced perspective acknowledging that not only males but also females can benefit from …

Happy to announce this #preprint , the culmination of last 10 years. 🥳

We find that #antimicrobialpeptides are evolved to control specific #microbiome #bacteria. This example is a textbook case of host #immune #evolution being shaped by the microbiome 🦠 which depends on host #ecology.

Thanks for comments! Bit of an experiment: we are posting pre-submit to get feedback 🙂.

Single innate immune effectors control ecological microbiome bacteria across evolutionary timescales

Antimicrobial peptides are host-encoded antibiotics that combat invading microbes and help shape the microbiome in plants and animals.
