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.

Oscars for birds? Count me in. We cannot deny that the Killdeer deserves recognition for their amazing performance as a wounded prey item to distract predators from their kids #birds #BirdOscars

“Novelty” of approach is overrated and no I won’t be expanding on this.

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.

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.

Ecological trap might work but it is specific to an attractive place with poor demographics. Population sink is poor demographics without the attraction. There are prob some other useful terms too

Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

Scientists dream of describing new species, not writing their obituary and epitaph, knowing that they are gone forever #ornithology

So many people have made personal sacrifices working every day to improve living standards for all of us. They are heroes that often go unrecognized and deserve better. I'm thinking about you all today.

Demographic trends for the Boreal Owl, Aegolius funereus, using standardized migration monitoring data in eastern North America Many boreal species have declined during recent decades in North America. Various indexes suggest that populations of the Boreal Owl Aegolius funereus are declining across North America, but very f...

Check out our latest where we look at long-term trends of Boreal Owl captures, juvenile captures, body condition, and cycles. Great work Justine Le Vaillant! A collab with @hawkmountain.bsky.social

Someone please do this with Grasshopper Sparrows. It would be pretty wild because their early successional habitat can result from fires, agriculture, or mechanical manipulation. Cool study!

Or the opposite side of the coin. Maybe you all could talk about how excluding people from the economy damages the economy for everyone.

Let's pretend the economy is a pie. Does inclusion and diversity in the economy slice the pie into smaller pieces or does the pie just get bigger? (I strongly suspect the latter but it would be great to hear from experts).

Comparison of Bayesian Models to Estimate Survival From Dead‐Recovery Alone and Together With Live‐Encounter Data: Challenges and Opportunities Different models in the Bayesian framework for analyzing dead-recovery data, either alone or together with live-encounter data to estimate survival, are presented and compared. Although all but one o...

Here's an extremely useful study for those using survival models that compares different implementations. Just my luck, guess which model I had been using for a not-yet-published study. onlinelibrary.wiley.com/doi/10.1002/...

I'm finding as I make more complex models I seem to need to use the noncentered param more to get adequate sampling. Any chance you've had a similar experience?

okay I probably wouldn't have used it then. Still that team is always adding nice features.

Honestly I think one of your previous posts brought this to my attention, so thanks! I was not aware that nimble had a built-in noncentered sampler. I probably should be using that.

And obviously this won't rescue a poor dataset, but it might rescue some poorly behaved MCMCs.

Just sending this out to the BlueSky-iverse in case any of you Bayesians are struggling with convergence out there.

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.

Please, please, please-submit to good journals (society + reputed publishers), respect peer review, and do your reviews with integrity. So important. Thanks to all of you who do. @steve-carpenter.bsky.social @esajournals.bsky.social #Ecosystems

Latest achievement, I made my model indices spell s,c,a,t. Thats sex, captivity, age, and time. Sadly, my study has nothing to do with actual scat.
