Evidence synthesis researcher, meta-analyst, and occasional ecologist. Working on AI in reviews, open science, and better research methods for conservation. NINA, Trondheim. Still rather fond of pheasants.
Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.
New blog post! Odds ratios are...a bit weird. Here I explain two problems (interpretation, non-collapsibility) and provide some simple recommendations for improved reporting. www.the100.ci/2026/07/30/r...
Reviewer notes: Odds ratios are really odd
When psychological researchers investigate binary outcomes, they routinely report odds ratios to quantify the strength of an effect or an association. This is quite understandable given that psycholog...

Let’s embrace wildfires, droughts, floods and climate change that will get progressively worse and more destructive Let’s embrace ecosystem collapse, food shortages, threats to infrastructure and economic disaster
Why do so many ecological systematic reviews cite PRISMA but not the CEE Guidelines? Are we teaching reporting standards but not conduct standards? Curious to hear from editors, reviewers and those teaching synthesis in ecology. #EvidenceSynthesis
🐦 Thrilled to share our latest research, a milestone: the first first-author paper from @shreyadimri.bsky.social, published in @royalsocietypublishing.org Why do birds add fresh green nest material to their nests? 🧵 🔗 doi.org/10.1098/rspb...
I can't stress enough how disrespectful it is when colleagues in the Global North publish papers about our realities without a single author from the region. It's not "just data." Context matters. Interpreting our realities through your own framework isn't just exclusionary, it's weaker science.
Does anyone what to review an exciting paper in #ResearchSynthesisMethods on LLM screening in systematic reviews with complex inclusion criteria? #SystematicReview Let me know if you have capacity.
Delighted to see this paper finally out after a long time in the making. Huge thanks to everyone involved—and to all those long nights spent on the cliffs catching these incredible little birds. 🥳🎉 @stephen8vickers.bsky.social #seabirds #ornithology

(1/) This week, we head north for an interesting study that was conducted by Nord University in Norway. It used an online bird identification test to upskill survey volunteers in order to increase the number of species that were detected during surveys. @btobirds.bsky.social @jncc.bsky.social
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
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...

We built a hotel for roof-breeding kittiwakes on Røst and share our first experiences in a paper now published in SEABIRD, with recommendations for those attempting a similar project. High attendance but few breeding attempts in the first year. doi.org/10.61350/sbj... 📷 T Anker-Nilssen

Automation is a means, not an outcome. Our @sinisavilaakso.bsky.social, @nealhaddaway.bsky.social , @chrispritchard.co.uk latest commentary argues that we should be careful not to equate AI-assisted automation with demonstrated efficiency in evidence synthesis. rdcu.be/frFVC
Automation is not evidence of efficiency

Only in Norway? We saw this grill mounted on skis on our hike today.
If you need to do a lot of work to make model explainable, you didn't make a (good) model
Today we are running our AI-assisted Coding Workshop at Nord University in Bodø (Norway)! We couldn’t ask for a better setting: an amazing location, inspiring surroundings, and excellent infrastructure for learning and collaboration.
