Climatic variability drives greater thermal tolerance breadth and enables larger range size in butterflies Abstract. Although climatic variability has been proposed to shape physiological tolerances, and in turn, species distributions, relatively few studies hav

We found support for the Rapoport effect in butterflies 🦋 species that live in more variable climates have broader thermal tolerances and larger range sizes. A collaboration with Aaron Yilmaz and @sarahdiamond.bsky.social 🔬

Species on east-west coastlines are more likely to go extinct than those on north-south shores – new study 500 million years of fossils reveal how ‘escape routes’ along coastlines can decide who survives climate change.

Very excited to share that my first first-author pre-print is out today! Many thanks go out to all of our collaborators, especially those who helped with the fieldwork in Peru - it really wouldn't have been possible without you! 🦋

Our paper on the mysterious Devonian organism Prototaxites has now finally been published! See the paper here (www.science.org/doi/10.1126/...) and our explainer thread below!

New paper alert! Microclimate temperatures are more extreme than we previously thought! Near-ground temperatures are amplified in hot weather, cool refugia is lost and replaced with heat traps ☀️🔥🥵 escape from heat will be very hard for small ground-dwelling organisms

Had an absolutely fantastic time at #BES2025 and a massive well done to all speakers and presenters. Really enjoyed displaying my poster and research, representing two great unis, and meeting so many great people and potential collaborators. Glad my title brought as much joy to others as it did me!!

Tips and tricks for writing constructive peer reviews Peer review has been the cornerstone of scientific inquiry for centuries and is considered the backbone of scientific quality and rigour (Spier, 2002). Des

Great to be a part of this study quantifying the potential negative effects of conservation work to protect one taxon on others! Turns out studying eels did not negatively affect water birds in this case🦆🦢👍

The impact of boat activities associated with an acoustic fish telemetry study on waterbird populations in a Special Protection Area It is widely recognized that the research techniques used to monitor and study wildlife have the potential to disturb and alter the behavior of the study species. However, other impacts on sensitive,...

New paper out! 📢 We tested whether boat activity from an eel telemetry study disturbed protected waterbirds in a UK reservoir.

🦆 No evidence of disturbance.

Temporal Increases in Mercury Concentrations are Associated with Increased Risk of Death by Infectious Disease in Harbour Porpoises (Phocoena Phocoena) Trace elements, particularly heavy metals like mercury, pose significant risks to marine ecosystems due to their toxic and bioaccumulative properties. Concentrations in some marine species show concer...

We’ve found concentrations of mercury in UK-harbour porpoises is increasing. 📈🐬

We also found concentrations of mercury were associated with an increased risk of dying from infectious disease.☠️

Seeing a lot of racist pinkwashing bullshit about Muslims and homosexuality and it’s a good time to share how I was on the gay marriage beat for a decade and racist gays never believed me when I shared how US Muslims favored equal LGBT rights (52%) over Christian evangelicals (34%)!

🚨 Important paper for understanding limits on range expansions under climate change. 🚨 Wall Brown's shift their life history to expand polewards, but are ultimately limited by winter tolerance. Perhaps physiological tolerances just can't evolve at the same pace as other traits... 🦋❄️

New paper in @pnas.org — and this is my favourite one out of my PhD thesis! Field transplants of wall brown butterflies show life history evolution during climate change-driven range expansion, BUT non-evolving winter tolerance still sets the range limit.🧵1/12. doi.org/10.1073/pnas...
