Finally, the circle closes: the last chapter of my PhD thesis is out! Proud to share our findings: royalsocietypublishing.org/d… @CleliaGasparini Below, a little thread 🧵

Sperm performance in the race for fertilization, the influence of female reproductive fluid

Abstract. In studies of sperm competition, particularly in external fertilizers, the importance of the fertilization environment on the paternity share amo

In this study, we reveal the association, in magnitude and direction, between the effects of FRF on sperm and the paternity share among males, demonstrating that the FRF can even overturn intrinsic sperm performance.

This work thereby posits the change in sperm performance prompted by the FRF as a robust proxy for the paternity bias induced by females.

New paper out in Biology Letters @RSocPublishing. I couldn't be more proud of being part of this all-female team shedding light on female mechanisms of fertilization control. Check it out here 👇

Finally the very first paper of my PhD is available online at @ASNAmNat! With @CleliaGasparini, @fedepolipoli, A Grapputo & MB Rasotto we show how female reproductive fluid increases the opportunities for post-mating sexual selection. Sneak a peek here: journals.uchicago.edu/doi/ep… 👇

Using the Zebrafish we first tested the prediction that female reproductive fluid (FRF) prolongs the egg fertilization window (spoiler: it does!)

Then, we show how FRF, through its effects on the egg fertilization window, increases the degree of multiple paternity, adding a new piece to the puzzle of female post-mating control in external fertilizers.
