Predation drives life history and morphology evolution? We tested the classic textbook story of guppies and their predators 🐟🐟

Out now: our meta analysis on male ejaculate aging in non human animals @natcomms

Brief summary here👇
6.Fish and bulls show improvement with age in ejaculate quantities, possibly due to indeterminate growth and selective culling
7. Reproductive outcomes less likely to senesce than sperm traits, maybe due to female driven buffering effects (small sample sizes)
No evidence for male reproductive senescence across non-human animals ⚫️〰️
Specific taxa show senescence in some traits + lifespan sampled is key to detect it

Very exciting to see this one finally out!
Please retweet: Excited to announce that a fantastic collection of ASN VP SYMPOSIUM papers on "The Power of Sexual Selection" led by early career researchers is now available. Check them out, read them, cite them and hire these people! journals.uchicago.edu/toc/an…
A great seminar by the amazing @LoeskeKruuk on the lovely fairy wrens @egioxford
💥Paper accepted @ASNAmNat 💥w/Lauren Harrison and @Mikejennions
Are males that always win better than losers when it comes to sex? Only when it comes to mating behaviour, not sperm.
Part of the special issue “Power of Sexual Selection”

Thank you @FrontiersIn for the highlighting our new paper!
Honeybees exposed to modern pesticides have an impaired optomotor response, shows research. This impairment is accompanied by damage to brain cells and dysregulation of detoxification genes.
Read the study in @FrontInsectSci: fro.ntiers.in/6535 or our news story ⬇

Super proud of this Work by @JGMussoi @mc_stanley1 and I. Does a crappy nights sleep screw up bird vocalisations? We think probably so, but very little research out there.

Come check @waele_hannah poster (#80 level 5), she shows how predation pressure on #guppies affects offspring production. Interesting to see that somewhere out there predators actually do get to eat some guppies in an environment setting 😵

Where have all the males gone?
Ironically, we show that life history data is biased towards females using two different data-sets
Proud of an all-female authored paper w/Ruth Archer, @m_paniw @iremsepil @RSocPublishing

Got to know great people while learning about proteomics @EBItraining. Now looking forward to analysing my junglefowl 🐥 sperm data 🤓
Can direct predation impact relative brain size and brain anatomy?
We found females surviving to predation had larger brains, while smaller survivors showed relatively smaller brains: link.springer.com/article/10…
Always great to work with @catarina_vp @DrDJDavidJ @KotrschalA
