This week has been one of the warmest on record in Oxford. This heatwave has also been recorded by the thermologgers we have in @wythamwoods.bsky.social. The period between 23rd and 28th May has been ~8°C (+2.6 SDs) warmer in 2026 than the same period between 2023 and 2025.

New paper out in Biological Reviews📝🚨 When trying to explain why female birds engage in extra-pair copulations/paternity, we mostly focus on the benefits. But what about the costs? Should we not consider the downsides of the behavior we try to understand? 🧵 onlinelibrary.wiley.com/doi/10.1002/...

The costs of extra‐pair behaviours in birds

Extra-pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecol...

Planning a nestbox temperature manipulation experiment in birds? We’ve just published a preprint that may be useful! 🪺🪶 We review 46 studies and also share our own blue tit pilot experiment from Wytham Woods, highlighting some very real practical challenges doi.org/10.32942/X25387

1/🧵My first preprint!🐛🌡️ We examine how environmental effects experienced during one life-history stage persist and modulate environmental responses in later life-history stages. With Lea Beaupere, @sheldonbirds.bsky.social, @rona-learmonth.bsky.social www.biorxiv.org/content/10.6...

Great talk by @rona-learmonth.bsky.social at #BES2025 on the absence of small scale local adaptation by winter moths to oak tree bud burst. Read more in this preprint www.biorxiv.org/content/10.1...

New preprint! 🌳🐛 We combined experimental and genomic methods to study local adaptation of winter moths to variation in oak budburst timing in Wytham Woods, UK. With @andreaestandia.bsky.social, Lea Beaupere, Ella Cole, and @sheldonbirds.bsky.social www.biorxiv.org/content/10.1...

Integrative analysis of fine-scale local adaptation of winter moths to variable oak phenology

For herbivorous insects whose fitness depends on tight phenological synchrony with host plants, spatial variation in plant phenology can impose strong selective pressures and promote local adaptation ...

Last week of winter moth trapping along the Phenoweb transect between Edinburgh and Inverness. We aim to study the spatial scale of local adaptation to oak phenology 🦋🌳🧬 with @rona-learmonth.bsky.social, @allyphillimore.bsky.social, @nilomr.bsky.social (and @sheldonbirds.bsky.social back in Oxford)
