Ecologists love response ratios for meta-analysis❤️ But… they can’t be converted into other effect sizes—making it impossible to have a unified dataset of all published effect sizes in ecology I fix this with a conversion to Hedges’ d to help unify our data! (Link to Ecology Letters paper below):

Sorry college kids circa 2015-2016, I will no longer be retaining your exams in my office ❤️ 😭🧪

Look at this little fledgling blue jay! 🐣 ❤️ 🧪
Our 7 foot yard gator 🐊 hasn’t returned yet this year, but we welcome this new little 2-foot cutie today ❤️ 🧪
My latest blog on evidence synthesis in ecology. We often see reviews that claim to have followed PRISMA. But PRISMA is not a conduct guide but a reporting guideline. Why does this matter? Have a read and find out! «PRISMA is not the method you are looking for». drmattg.github.io/Uncertain_Ec...

It’s easy to miss seasonal changes in Tampa — but our favorite marker is when the common snapping turtles 🐢 come out to eat our orange Queen palm 🌴 seeds — this event also signals the return of our yard alligator! 🐊❤️ 🧪

@lajeunesselab.bsky.social has written the paper that meta-analysts were waiting for, and I can't recommend it more: Converting and Constructing Effect Sizes With the Response Ratio doi.org/10.1111/ele.... Go check it out (and use it!)

TIL: random effects meta-analysis in Excel, thanks to @lajeunesselab.bsky.social 's perfect YouTubeTorial (Yes I can program & use stats software, but until I crunch the numbers in a spreadsheet, I don't really understand it. Now I know Kung Fu) ps: it's as easy as ANOVA youtu.be/i66Lf2a_Pa8?...

Ecological meta-analyses often inherit medical assumptions. High heterogeneity, small sample sizes, etc. break those assumptions. In the first post of a new series, I show why a “significant pooled effect” can be statistically correct but practically unhelpful. drmattg.github.io/Uncertain_Ec...
