Pre-print now out on bioRxiv! If you saw my talk at #eseb and want more info, here it is:

Exciting new pre-print from the group! Why and how are our owls getting redder over time? 🦉

Check it out on BioRxiv 👇👇

A couple of really cool conferences happening next summer on my birthday 🥲

I know many people have a conference birthday but I just can't bring myself to do it ... me and my partner usually go on holiday and yes I'm turning 30 next year 😬

With #eseb2025 coming to a close, it is time to start making plans for 2026. Interested in the interface of evolution 🧬 and ecology 🌳? Come to our #ExE conference hosted by @uniexecec.bsky.social in beautiful #Cornwall. Leave your email address at tinyurl.com/EvolxEcol to join our mailing list!

I'll be presenting at #ESEB25 tomorrow! Pop along to room 114 @3:30 if you want to hear about inbreeding depression, hierarchical models and barn owls of course 🦉
S42.02 - looks like it's going to be a great session! 😊

George RR Martin is an author on the dire wolf paper. Presumably to make sure there’s plenty of incest, cos these wolves will have no one else to fuck except each other.

1/7 Sexual antagonism arises when males and females face different selection pressures for a trait influenced by shared genes. This is thought to drive balancing selection and maintain genetic polymorphism. We challenge this view in our recent paper :

The maintenance of genetic polymorphism underlying sexually antagonistic traits
Abstract. Selection often favors different trait values in males and females, leading to genetic conflicts between the sexes when traits have a shared gene

Inbreeding depression is more severe in harsher environmental conditions, as shown in a wild population

Thanks to my amazing supervisors: Josephine Pemberton and @susanjohnston.bsky.social , and my lovely co-authors too Greg Albery and @seanofrum.bsky.social and Ali Morris at @rumdeerresearch.bsky.social

Slightly surreal that the PhD is now 'officially' finished ... but who knows 😉

💪 BUT ... there's always lessons to be learnt about power, and turns out you need a lot of variation in environmental conditions as well as inbreeding (hence why it's rarely been found in the wild), which we discuss too

📈 We show that inbreeding depression is worse in the harsh northern regions of the study area where survival is lower, indicating that the severity of inbreeding depression changes across fine-scale environments (i.e. ID × E)

Only a few studies have shown evidence for this interaction in the wild!
