Théo Bodineau: The impact of nocturnal warming and prey availability during reproduction in a viviparous lizard In this week’s blog post, we’re checking our calendars and addressing how climate change is causing shifts in breeding dates for reptiles! Discussing the article “A multi-trait evaluation of patter…

👀Behind the paper!👀

🌙Théo Bodineau discusses the impact of nocturnal warming on breeding and gestation in lizards, the challenges of caring for them, and transitioning from medical school to ecology🦎

Really happy to share our new paper ! We characterized the Morpho butterfly visual system, and found a link between opsin evolution, wing coloration and light habitat. We also highlight correlated evolution between amino acids from different opsin genes at a molecular scale !

In 2024, Infant and Child Development (ICD) withdrew as a PCI RR-friendly journal and reneged on three Stage 1 recommendations issued by PCI RR. In addition, Wiley – the publisher of ICD – notified PCI RR and the PCI core team of its decision to withdraw all Wiley journals from PCI and PCI RR, including an additional 9 PCI-friendly journals. Finally, Wiley appears to have banned all of its ~1600 journals from considering submissions that have been previously reviewed by PCI or PCI RR. This statement explains the history of ICD joining PCI RR and developments that led to the current outcome. The PCI RR Managing Board believes that this shift in policy to become “PCI-hostile” renders Wiley journals incompatible not only with community-based preprint review but with preprint archiving in general.

Oval-shaped mollusc with stunning patterns in orange and white. The animal has eight more or less oblong shells that articulate with each other at the long edges. It kind of looks like a steampunk armadillo, if an armadillo didn't have a head, tail or legs. And was mechanical. 

The shells have an unpatterned triangle along the midline, with slanted patterns of bright orange, dark orange and white. 

The chiton is on a rock and is surrounded by barnacles.

Stunning bright red and white chiton that looks so obvious but is nestled on a background of pink coralline algae. It might not be such a striking contrast to a more casual glance. (Or with non-colour vision.)

This creature looks like a tapestry. The girdle (which runs around the edge of the shells) is wide and a superb crimson with little beige spots at the edge that make it look frayed and break up the smooth outline. 

The eight shell valves are red, black (or very dark red) and white and the line pattern is ragged, so it looks as though it's been embroidered. The impression is not of a hard mineral surface, but of velvety fabric. 

This species is very variable in colour and this pattern is not the most frequently encountered, but it's too lovely to ignore.

After the orange and red chitons, this one is much more cryptic, but it's included to show the range of shell shapes. 

Like the others, this has eight shells or valves, but they are small tear-drop shaped shells that articulate with each other at a narrow point. They look like a spine protruding from the mottled grey-green tissue of the girdle. 

Apologies for that mental image. The actual image is less off-putting.

Back to the pretty chitons! This one is blue, white and brown. That combination doesn't sound promising -- you probably wouldn't paint your living room in those colours -- but it works on this mollusc. 

The girdle looks like snakeskin (with tiny scales) and is banded in pastel blue and light brown. The shell valves have broad brown triangles along the midline, which are overlain with pale blue streaks and bright blue dots. On either side of those brown triangles, a pattern of light brown lines and zigzags radiate to the edge of the shells. It's not vividly hued but it is a lively pattern.

This thread asks the question on everyone’s mind: What’s the deal with chitons?

First, some of them are really lovely. (1/11)
