Congrats to Alessio De Nardo, who just published his MSc and first ever paper in Evolution Journal. It shows that small male #drosophila may have poor mating success, but they can make up for it in other ways... onlinelibrary.wiley.com/doi/10.1111/ev… #sexualselection #spermcompetition #reproduction

Distinctive weaponry, ornamentation or sperm quality - male animals have to be especially dominant or attractive if they want to woo females. Biologist Stefan Lüpold examines which features increase the mating success of a species and why: news.uzh.ch/en/articles/20… UZH Science

Congratulations to Erin Macartney and Valzee who spearheaded this effort: onlinelibrary.wiley.com/doi/abs/10.111… Also many thanks to Abhishek Meena, Ph.D., Alessio De Nardo and Russell Bonduriansky for their important contributions to this collaboration.

Now that it's all nicely copy-edited and open access, here is our new paper examining the effects of diet and genetic background on sperm depletion and fitness in D.melanogaster Valzee Abhishek Meena, Ph.D. Alessio De Nardo Russell Bonduriansky Stefan Lüpold doi.org/10.1111/evo.14…

(1/3) I typically look at GCaMP in neurons, but here is GCaMP in eggs during ovulation! An individual egg (red arrow) travels from an ovary to the uterus. The egg is then activated (increase in fluorescence is due to calcium influx) and eventually deposited. [5X speed]

Fantastic PhD defence by Valérian Zeender! Congratulations 👏🏻 👏🏻. The best memories from when we counted nearly 950,000 sperm 😎 Abhishek Meena, Ph.D. Alessio De Nardo Stefan Lüpold

Congatulations to Abhishek Meena, Ph.D. on the first chapter of his PhD that just went online. Fertility loss and recovery dynamics after repeated heat stress across life stages in male Drosophila melanogaster: patterns and processes | Royal Society Open Science royalsocietypublishing.org/doi/10.1098/rs…

Abhishek Meena, Ph.D.'s new paper shows how just a brief heat pulse during a vulnerable developmental stage keeps #drosophila males nearly sterile for days after emergence. Females are not affected.

Humbled and proud to be part of this fantastic collaboration leading to this study in NatureEcoEvo on the genomics underlying ornament-preference coevolution. Kudos to Zeeshan for leading this massive effort and thanks to all collaborators. doi.org/10.1038/s41559…
