Decomposing leaf mass into metabolic and structural components explains divergent patterns of trait variation within and among plant species🌿

Decomposing leaf mass into metabolic and structural components explains divergent patterns of trait variation within and among plant species - Oecologia

Across the global flora, interspecific variation in photosynthetic and metabolic rates depends more strongly on leaf area than leaf mass. In contrast, intraspecific variation in these rates is strongl...

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

genzplyr is dplyr, but bussin fr fr no cap.

Rにまつわる怖い話をいくつか書いてみました。lmerのデフォルト設定がREML=TRUEとなっており、モデル選択できない使用になっているのに気づかず、やらかしてしまっている論文はかなり多いのでは、、と思ってます。

When do girls fall behind in maths? Gigantic study pinpoints the moment

https://go.nature.com/4l1nC4g

Watch the mathematics gender gap emerge. The school environment triggers a gender gap in mathematics. Line charts showing test results from all children in France who started school in 2018 reveal the trend. At the start of first year of school boys and girls similar on average with slightly more boys in highest and lowest percentiles. At the start of second year of school the gender gap becomes more exaggerated.

Analysis of ~80,000 peer reviews in computer science showed (i) papers from Asia/China/TOEFL-required countries receive lower ratings, (ii) this bias slightly reduced post ChatGPT, (iii) reviewers now link ChatGPT "style" with scholar origin, then with the quality of science:

🌳 How long do trees really live?
Our new study in Nature Ecology & Evolution reveals that Japanese trees can have a potential lifespan of ~400 years, but most live only ~80 years. Huge congrats to first author Yuta Kobayashi for this fascinating work! 🎉

Climatic differences among habitats shape the balance between maximum lifespan and life expectancy in Japanese tree species - Nature Ecology & Evolution

Using Japanese forest census data, the authors define potential maximum lifespan and life expectancy for 53 tree species, finding that life expectancy is more sensitive to habitat-associated gradients...
