After last year's successful refresh of the BES Reproducible Code guide (www.britishecologicalsociety.org//wp-content/...), this year we're going to refresh the Data Management guide (www.britishecologicalsociety.org//wp-content/...). Exciting! See below for how to get involved...
Congrats Jingyi! Well earned. Gutted I couldn't be there but we'll celebrate soon!
Delighted to have had a small part in this very cool paper - my undergraduate final project contributed to the dataset. And big congrats to Rob and the others on the outcome! 🎉
I have some PhD projects now available for application if you are interested in insect biodiversity change. Please check out the links below and shout if you have questions!
And @obarker.bsky.social !!
Sorry I couldn't find you on blue sky in my rush to post before leaving work 😅
🙏 Thanks to my incredible co-authors and collaborators! Especially @josephtobias.bsky.social who started collecting data yonks ago, but also
@jyang19.bsky.social
@timjanicke.bsky.social
and many others who worked on the dataset at

🌟 This brings me to my last/proudest point (and well done for making it this far). 🏁
🗂️ Our dataset is freely available for all avian species and matched to multiple taxonomies. Hopefully it can help advance research on sexual traits, macroecology, and birds in general 🐦
While historical biases dominate data quality, our analyses confirm the gradient still holds for the fraction of best-known species. Moreover, because of a multitude of reasons, sexually selected species (especially tropical) are better known, which can also dampen global trends
Diet also matters:
Frugivores show weaker sexual selection at higher latitudes (a reversed trend).
In comparison, Insectivores show the strongest positive gradient.
This divergence highlights how ecology can shape the relevance of sexual traits across of species. 🦟🍇
Ecology and climate provide the answers. Species in seasonal environments (common at higher latitudes) experience greater sexual selection, perhaps due to restricted breeding seasons and greater competition for mates.
Key result: Sexual selection intensity follows a striking latitudinal gradient, increasing toward higher latitudes! 🗺️ Birds in temperate zones exhibit more intense sexual selection compared to their tropical counterparts. But what drives this pattern? 🤔
We first combed studies, books, databases, encyclopedias, and expert advice to score sexual selection across thousands of species, validating information on mating systems and courtship behavior against established metrics (e.g., Bateman gradients).
Sexual selection shapes incredible diversity in bird traits, from extravagant plumage to complex displays. Yet, why it varies across species and regions remains a big question in biology. We set out to explore this using data from >10,000 bird species globally. 🌎🐦
Big news! 🎉 My first PhD chapter has been published in @PLOSBiology, and it just made the cover! 🐦🌍 Perfect time to dive into the key findings from our global study on sexual selection in birds. 🧵👇
