Are seminal fluid proteins a male tool to manipulate females against their interests? Or do females have a say as well? Michalak et al. argue that if females can detect seminal fluids, using it as information can benefit both sexes. Read now ahead of print! www.journals.uchicago.edu/doi/10.1086/...

Compelling meta-analytic evidence for female fitness benefits of polyandry in arthropods by Yan et al. academic.oup.com/evolut/advan...

Led by my talented PhD student @justine-armg.bsky.social we’re running a #meta-analysis of #cross-sex-genetic-correlations in fitness components. If you have unpublished data or know of studies that might not appear in a systematic search, please reach out, we’d love to include them! Please share!

A study uncovers the mechanisms by which a parasitic wasp uses a virus that it produces from its own DNA to disrupt the development of the testes of its moth host, diverting host resources that would have gone to reproduction. In PNAS: https://ow.ly/uCMe50Yf4l6

With respect to female adult performance, Chung et al. found elevated temperatures alone led to faster life histories with lower reproductive output, while early-life food shortage had no effect. Available now ahead of print! www.journals.uchicago.edu/doi/10.1086/...
