Could not help myself but laughing when I saw what the drop down menu offered me today as suggestions, no doubts based on past choices, regarding personal profile keywords in a journal's reviewer system

Not been here for a while, I though I would today to commemorate the 25th of April 1974. If don't know what it represents for Portugal, visit the website that was built to commemorate the 50 years of the revolution (which was last year) which includes lots of information about it:

O problema do país parecem ser os imigrantes criminosos, com valores de criminalidade residual, e os deputados do chega, onde a proporção de criminosos ronda os 20% www.publico.pt/2025/01/22/p... não os podemos mandar fazer as malas 😝 e enviar para o país deles? Aí, espera... o pais deles é o nosso.
Quase um quinto dos deputados do Chega teve ou tem problemas na Justiça
Pelo menos nove dos 50 deputados eleitos do Chega já tiveram processos na Justiça. Miguel Arruda é o caso mais recente.

A cool example of using a model for (multi) species abundances to reconstruct an image (unrelated to species abundances!), by treating the RGB channels as 3 different species. It's remarkable how you can get a good idea about the overall picture just from RGB values on a very small sample of pixels.
spAbundance package (Doser et al. doi.org/10.1111/2041-210X.14332) was published this year at
@methodsinecoevol.bsky.social! It fits a variety of single/multispecies abundance models using Bayesian Inference allowing also for hierarchical frameworks. Let me show you a funny example 🧵👇(1/6) #rstats

It is disturbing how a few men are now capable of electing a President in what was once an example of democracy, and worse, that they can silence the "free" press about it without consequences. That seems the theme of the century. No consequences, no accountability open.substack.com/pub/anntelna...

Great diversity. I might be quite marine mammal biased... I'll go with bowhead whale, Commerson's dolphin, polar bear, narwhal and chimpanzee.

Insightful post from Peter Ellis on the relation between depression levels at the US county level and proportion of Trump voters. Code to gather data + run analysis available. Cool analysis illustrates how logistic regression might severely underestimate precision freerangestats.info/blog/2024/12...
Depression incidence by county and vote for Trump
Multi-level modelling with spatial auto-correlation! I look at county level data on incidence of depression in 2020, and voting for Trump in the 2024 US Presidential election, and conclude that there'...

Animal movement workshop alert! A line of speakers difficult to beat with John Fieberg, Marie Auger-Méthé, Brett McClintock & Inês Silva and the location is definitely a place that makes you "move" for it: lovely Madeira. 19-23 May 2025. Just after the ECS in Azores. It's PT islands 2025. See you?

Today was the last day of Ecological Modelling classes, I "offered" the students a full day workshop where I would work with them and their final assignment models. Yesterday we had a little get together to celebrate end of term. What a great class. #WorkHardPartyHarder

Near-0 probability event: level unlocked. Today I was the external examiner of an MSc dissertation. Drove to a different uni. A car hit me from behind (really far from the uni!). A few chaotic minutes later... the MSc's student boyfriend was the co-pilot, his cousin the driver. What are the odds??

The dream team today at Feira da Matemática at Museu Nacional de História Natural e da Ciência, (yesterday schools and) today helping the general public know how we count wild animals. Thanks Matilde Correia, Miguel Martins and Gabriela Xavier-Quintais, all students of the Biostatistics MSc at FCUL.

Today I was at Museu Nacional de História Natural e da Ciência, at Feira da Matemática, with an activity about how to count animals. Highschool kids and as usual some climate change, Dunning-Kruger effect, passive acoustics density estimation, ACCURATE cue rates, distance sampling, capture-recapture

Making my first post here in a long time, but as many others more and more disappointed with twitter each day. How's the environment around here? Are there fundamental things to do/not do here? Any pointers greatly appreciated!
