Hi all, I started my winter session meta-analysis course on YouTube! Join me as I muddle my way through an entire synthesis project. It’s meant as an entry to research synthesis, so expect some lighthearted fun with new posts nearly daily :-) youtu.be/rM4MQA5hU6c

Here’s an old vid where I outline the problem… I was wrong in so many ways, but articulating the problem out loud help push me take the problem more seriously 😊 youtu.be/a4D-DSKE2J8?si… via @YouTube

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 fixed this with a conversion to Hedges’ d !! Link to paper below:

Alhamdulillah! Exciting News 🌳 Our meta-analysis on the effects of tree diversity on forest transpiration has just been published in Journal of Ecology! A big thank you to my amazing co-authors for their collaboration and hard work! @aumaheu @JEcology

Thanks! This is so cool! Maybe I should start reposting again 🤔

Curious about teaching meta-analysis?🤨 Catch my talk about how my approach to teaching this tool has changed throughout the years Starting at 05:00 AM EDT on YouTube during the 2nd day of the ESMARConf2025 conference, link found below ⬇️

Narrow AI trying to make sense of my porch

@USouthFlorida has been planting many ornamental cycads 🌿 on campus and the result has been this wonderful explosion of 10,000s coontie hairstreaks this week!! ❤️🦋

@smartereveryday Juicr is relatively easy to get the hang of. If using Mac, closing X11 really upsets R Studio, so make sure to save your work before closing X11. youtu.be/tiL-gZgN9Qk?si…

@BellaLGonzalez @OAcevedoCharry Oh wow, was too busy to have a closer inspection at the time, but way cool!

We are in the clear! #Milton did bring some eel riverwash though

As I have a🍺 & wait for #Milton to take my home… I’m reminded of simpler times, when I decided to post +25 hours of #YouTube videos of me doing a complete meta-analysis from scratch on a topic I barely knew anything about Do what you love friends! youtu.be/rM4MQA5hU6c?si…

Very proud of @coraliewilliams 's first #PhD paper @MethodsEcolEvol ! Improving reporting of statistical simulation studies for EcoEvo and beyond besjournals.onlinelibrary.wiley.com/doi/10.1111/20…

Meta-analysis is formal & explicit -- don’t get fooled by incomplete applications for synthesizing research But how do you separate the wheat from chaff? Here’s a 10min YouTube video of the 3 defining features of a high-quality meta-analysis 💪 youtu.be/3XkC_jetn-U

Meanwhile, here’s my yard gator 🐊😍 #Florida

A couple of months ago a paper in @science used a "meta-analysis" to summarise the evidence on the success of conservation action. @metanutter & I had a look at the paper and identified a number of issues that are applicable to many such papers 1/11

Nice #lighting in #florida tonight😍 #retrowave
