Wisdom of the crowd : when decisions are difficult and conformity bias is present, a little disagreement can make a group's decision more trustworthy than near-unanimous agreement, because dissent signals independent thinking rather than conformity. 📄 Boussard et […] [Original post on mamot.fr]

Figure comparing two groups making a decision: on the left, six identical figures form a “Full consensus” group, with everyone agreeing. On the right, six figures form a “Small dissent” group, but one figure indicate disagreement. A figure stands between the groups, asking which decision is more trustworthy. Full consensus may be more trustworthy for easy decisions or when people don’t conform, whereas slight dissent may be more trustworthy for difficult decisions when people tend to conform.

During flight, pigeons adopt a very stable gaze strategy: they dilate their pupils and reduce their eye movements in order to align their eyes with the axis of their vestibular systems. 📄 Ros et al. (2026) Pigeons lock their eyes in place during flight. Current […] [Original post on mamot.fr]

This composite image shows the experimental apparatus (a tiny camera on the pigeon's head monitoring both eyes) and an illustration showing the difference in eye movement when the bird is perched or in flight.

Contrary to our expectations, our study of the invasive round goby in Ontario found that bold, proactive personalities did not drive range expansion, challenging the idea that behaviour fuels invasion spread. 📄 Souques et al. (2026) Testing a personality-dispersal […] [Original post on mamot.fr]

High functional responses predispose fish species to invasiveness, but these trophic advantages do not necessarily persist outside their native range. Congratulation to Marine and Chloé for this nice paper! 📄 Courtois et al. (2026) Functional response predicts […] [Original post on mamot.fr]

This visual abstract of the paper shows two plots. The plot on the left illustrates that invasive species display a higher functional response. The right-hand plot illustrates that this difference only applies when the invasive species have been sampled in their native habitat.

Try to explain scientific journal publishing fees to non-academics... xkcd.com/2085

xkcd comic showing a discussion between two women. In the first panel, one woman says "wait, all the papers in your field are posted as free pdfs on arxiv? That must be killing big scientific journals since they charge such huge subscription/publishing fees." The other woman replies "Nah, we have been doing it since the 90s, and nobody seems to care". The first woman gets agitated and says "That makes no sense at all", when the other woman shushes her "shh, you'll jinx it".

International commercial trade is a major driver of ecological invasions. Unlike Suez canal, the Panama Canal had a lock system opened in 1914 which limited introduction of marine species. Recent expansion work has enabled the transit of mega-vessels. In this […] [Original post on mamot.fr]
