1/2 Personality in Sea Anemones
Despite lacking a centralized nervous system, Actinia equina displays predictable personality traits for each individual. This study shows that high temperatures increase their boldness and affect their ability to learn.

"While the handling and marking of chamois in this study were noninvasive, the method of capture (falling nets) nevertheless had the potential to cause high levels of stress and resulted in the deaths of five chamois." 🔽

1/6 Emotional/affective contagion in bumblebees
First evidence that emotions are contagious in insects too.
Bumblebees that observed an optimistic bumblebee became optimistic themselves.
This is the most basic form of empathy.

Beliefs about one's own beliefs in chimpanzees.
Five experiments have demonstrated that chimpanzees evaluate their beliefs based on evidence and the source of that evidence (by epistemic defeat). Language is not needed for any of this.

NEW PAPER: Female wild turkeys produce fewer male offspring where hunting increases male mortality, suggesting adaptive adjustment of brood sex ratios to enhance reproductive success under harvest pressure.

A l'heure actuelle, le livre est quasiment terminé mais la campagne de financement peine vraiment à se lancer, alors si vous voulez rejoindre l'aventure, n'hésitez pas à partager, participer, voire on peut possiblement discuter de sponsoring avec des structures :)
Merci!

Il y aura notamment deux gros blocs qui reprennent la plupart des travaux en metacognition et mémoire épisodique, mais aussi des travaux pionniers sur les émotions et plein d'autres aspects de leur vie mentale et sociale !

Josselin Billard et moi préparons un ouvrage de synthèse sous forme de BD sur la cognition et le comportement des rats. Pas loin de 1000 études en bibiographie.
Il est autant destiné au grand public qu'au monde universitaire.

Fingers crossed it survives review!

1/5 Birds around the world use the same alarm call to warn of the presence of brood parasites.
They studied 21 species from nine families that were separated by 50 million years of evolution. Perhaps the most interesting finding: the alarm call is learned.

1/8 Numerical cognition in birds
They handle quantities, proportions, simple arithmetic, etc.
The numerical cognition of birds is similar (sometimes superior) to that observed in primates, which represents an astonishing evolutionary convergence.
