Congratulations to @shreyadimri.bsky.social et al. on this fantastic contribution (and unexpected deep & convoluted rabbit hole 😜)! 🎉 📄 Paper: doi.org/10.1098/rspb... 📊 Data & code: doi.org/10.5281/zeno... ®️ Pre-registration: doi.org/10.17605/OSF...

Why do birds use green nest material? A systematic review and meta-analysis of experiments

Abstract. Many animals build nests. As external structures that can influence survival and reproduction, nests are often considered extended phenotypes. Bi

Nice! Self-contained reproducible #Rstats scripts or #Quarto documents Specify versions (or date) for R and R packages directly in the script or document

ir makes the runtime specification part of the source file. That means a script can say, directly: which packages it needs which R should run it, when that needs to be explicit whether user libraries should be visible whether CRAN packages should be resolved as of a specific date This should help you rerun the script reliably at a later date. Keeping the metadata in the file makes it less likely to be lost or fall out of sync with the code.Quarto documents too# ir uses the same metadata model for Quarto documents. Put package metadata under an ir: key in the document YAML: --- title: My report ir: packages: - dplyr>=1.0 - gt@1.0 isolated: true exclude-newer: 2025-05-15 --- Then render with: $ ir render report.qmd $ ir render report.qmd --to pdf When ir selects an R executable using --r-version, frontmatter ir.r-version, or date-only exclude-newer, it sets QUARTO_R so Quarto renders with that R. ir also seeds rmarkdown automatically for knitr-based renders unless you declare it yourself.

I'm happy to share `ir`, a new command-line tool for running portable R scripts and Quarto documents. It's inspired by my two favorite parts of `uv`: self-describing scripts and tools you can run without installing first. opensource.posit.co/blog/2026-07...

I always guide my students to do a quantitative bias assessment in their lit review, because it's the best way to highlight evidence gaps. This should be a standard for all systematic or quantitative literature reviews, not just formal meta-analyses.

Alfredo Sánchez-Tójar@asanchez-tojar.bsky.social · 3w ago

Are our ecological conclusions built on shaky foundations? Our latest paper in @methodsinecoevol.bsky.social highlights that Risk of Bias (RoB) assessment, crucial for ensuring the internal validity of research, is almost never used in #systematicreviews in eco & evo 📉 🔗 doi.org/10.1111/2041...

Richard McElreath 🐈‍⬛@rmcelreath.bsky.social · 3w ago

This looks useful. A typical meta-analysis in ecology mixes experiments with observational studies, mixes coefficients with different controls and therefore different causal meanings. I would not normally say "hey the folks in medicine are doing it right, imitate them" but in this case maybe

I think I was too vague & nobody engaged, so let me ask more directly: any ecologists & evolutionary biologists out there who pilot their studies? If so, could you briefly share what kind of piloting you do? 🙏🙏🙏

Alfredo Sánchez-Tójar@asanchez-tojar.bsky.social · 4w ago

In many fields, pilot studies are critical for methods & tool development & refinement, yet are often overlooked & rarely reported Any ecologists & evolutionary biologists with a special interest and experience in piloting in ecology & evolution: suggested reading, previous research, etc...?
