📢New paper!!
Really excited to finally share with the world our fabulous paper exploring the diversity of sperm storage tubule morphology across Galliformes, out now #openaccess in @Ecol_Evol with @HemmingsNicola1 and Paul Richards @EEB_Sheffield (1/9)

🚨 NEW PAPER ALERT! 🚨

Ever since the OG, Darwin, evolutionary biologists have been puzzled by the potential benefits females get by choosing "attractive" males. Well, good news Chuck, my grad school buddy Doug Barron and I figured it out today in @ASNAmNat! 😜 🧵 1/8

Check out the paper for more images and descriptions, for methods for #dissecting and categorising tubules in your own samples, and for some speculation as to the evolutionary significance of our findings and some enticing questions for future research (9/9)

...including channels that are sometimes long (and may end directly in a tubule), but may also be short and ‘funnel-like’. The existence of channels may have implications for our understanding of sperm transport, SST function and sperm selection within the avian vagina (8/9)

Delighted to share our latest paper, and the second chapter of my PhD, is now out in @royalsociety Proc B. With @HemmingsNicola1 @Jon_Slate @OMorton212.
We thoroughly explore the effects of a sex-linked supergene on reproductive traits in male and female zebra finches..

[Katherine Assersohn @kassersohn]

Despite the supergene having important effects for sperm traits, we found no evidence of an effect on reproductive traits in females. We do, however, reinforce the existing evidence that this supergene is being maintained by a heterozygote advantage for male fitness..

Check out our new guide on how to identify and get DNA from failed early embryos - step by step from field to sequencing! We hope this is useful for those that study captive or wild birds, from reproductive failure to selection, conservation and beyond! https://t.co/guMJkR4VVm

@rorylcooper @LANEVOL @ScienceAdvances @genevunige @sciences_UNIGE @UNIGEnews Wow! Congrats Rory this is amazing! 👏🥳

[Fay Morland @fay_morland]

The first paper of my PhD is out! We show that reproductive ageing across the whole lifespan of female hihi can be predicted by their telomere length at 21 days old! 🐣 @HemmingsNicola1 @P_Brekke @MirreSimons @hihinews https://t.co/4UZc9mdTzd

@fay_morland @HemmingsNicola1 @P_Brekke @MirreSimons @hihinews Congrats Fay!! Looks great :D

New #kakapo paper! We analysed what most affects fertility, one of the biggest issues for kākāpō recovery. Ranger and artist Sarah Little (https://t.co/902HSAThWx) provides the summary. Read the full paper here: https://t.co/9efuPz7jeV. #conservation

@Belfast_Ash9 Congrats Ashleigh this looks so cool! Can't wait to read it :D
