🦉We show inbreeding depression in morphological traits in a wild population of barn owls 📉 And that it manifests during early juvenile growth 🌦 We also show that h2 is lower in juvenile stages, because environmental impacts are higher

Abstract. Despite its detrimental effects, inbreeding depression in wild populations is relatively under-explored. Here, we use whole-genome sequence data

📃New paper in Ecology letters 🐦 I’m delighted to share the publication of the first paper from my #postdoc with @samanthacpatrick.bsky.social looking at life-history trade-offs and #senescence in black-browed #albatrosses from Kerguelen and Bird Island doi.org/10.1111/ele.70384
dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

🚨 New paper 🚨 (1/8) In meerkats, pregnancy isn’t one-size-fits-all. Some mothers gain weight steadily, others delay all growth until the final weeks 📈 What drives this striking variation, and how does it affect the (adorable) pups? OA PAPER: doi.org/10.1111/1365... Details (+cute pics!) below👇
🚨 PhD position available ! 🚨 I am hiring a PhD student to work with me on the evolution of plant sexual systems 🌺 at @unifrbiology.bsky.social ! The position is funded for 4 years by @snsf.ch as part of my Ambizione fellowship. More info here: tinyurl.com/monoecy 🌱 Please RP and share widely ! 🌱

Life-history theory predicts a trade-off between allocation of resources to reproduction or self-maintenance, yet how environmental variability shapes this trade-off remains poorly understood. We sho...
