Free advice. It is many orders of magnitude faster to recode and run your Population Viability Analysis in R than to run it in Bayesian software from an Integrated Population Model.

I've been wrestling with model convergence so I'm giving Empirical Bayes another try. Has anyone tried this out in their own research? Not seeking advice but curious about whether it worked for others.

A critical part of my "writing a manuscript process" has become jamming as much of my hard work into the supplemental materials as possible just before submission.

If youre using AI to help with coding/stats on manuscripts, be sure to get a code review from someone who actually knows how to code/do stats. The AI slop era has arrived.

I love condors. They are critically endangered and quite the characters. But they’re also incredibly important. With iron-strong stomachs, they are the disinfectants of ecosystems and protect from disease. We have much to improve in our relationship with them. www.azcentral.com/story/news/l...

Condors soar over the Grand Canyon, kept aloft despite lead ammo threat

The California condor nearly went extinct, and remains imperiled by the threat of poisoning from lead ammunition.

A preview of my upcoming talk at Raptor Research Foundation. Evaluating management of Ridgway's Hawk using IPMs and PVAs. Press play and watch the Population Viability Analysis go!

As of today, I'm officially an Elective Member of the American Ornithological Society (AOS)! 🎉🎈🎊 I always need to remind myself to stop and celebrate these things.

Using non-centered parameterizations of the normal and multivariate normal distributions has absolutely rescued a couple of complex models for several projects. It served me well when models become intractible or take too long to run.

Are you a US researcher who has recently moved to Canada because of the Trump disruption to science (or are you in the process of doing so)? I want to talk to you for a story in @nature.com 🧪
