Big new blogpost!

Monkeys have rhythm Synchronizing movements to music is a hallmark of human culture, but its evolutionary and neurobiological origins remain unknown. This ability requires (i) extracting a steady rhythmic pulse, or beat,...

New in Science, Macaques tap to the beat.

Very cool study for its main result and its null one: consistent with nearly every other comparative study of music, monkeys don't differentiate beats by their relative strengthโ€”which even young children do innately. Monkeys have rhythm but not meter!

Ooo yes of course! I used {styler} so much to help me format messy code into something readable over the years, so {Air} is definitely an important part of this clean code workflow. Thanks!

An excerpt from the paper

"Low neck mobility, combined with a mainly motionless posture, might have precipitated the decoupled eye movements and extensive eye rotation, and this association was previously reported in the seventeenth century. Thus chameleons, with their large orbits and extensive capacity for rotation, may benefit from the slack provided by the coiled optic nerve.

Wavy fibers have been identified in the optic nerves of rats, which allow the nerves to โ€œstretchโ€, but such fibers have not been found in the chameleon optic nerve. Convoluted optic nerve paths have been described in the larvae of the Ribbon Sawtail Fish (Idiacanthus fasciola). The eyes in the larval stage are supported by long stalks with a long optic nerve posterior to the stalk, but as these fish mature, the optic nerve shows gradual retraction and reduction of coiling. The occurrence of coiled optic nerves have also been reported among invertebrates; in the Stalk-eye Fly Cyrtodiopsis whitei long, coiled optic nerves develop inside the lumen during pupation, allowing for the rapid inflation and elongation of the eye stalks following eclosion."

The paper goes onto discuss how this long, coiled optic nerve trait is unique. Similar nerve structures are only found in a few animals, including the Stalk-eye fly which has some of the strangest eyes on the planet

Large-eyed animals like owls ๐Ÿฆ‰ have a trade-off between large eyes & short optic nerves, which lowers eye mobility (to compensate they evolved swivelly necks)

But chameleons ๐ŸฆŽ have long, coiled optic nerves with extra slack for eye mobility, allowing them to use their famous large swivelly eyes ๐Ÿ‘€๐Ÿงช๐ŸŒ

New #dataviz on summer heat-stress anomalies in Europe, 1950โ€“2025. ๐Ÿฅต

This map shows hours with WBGT > 29.5โ€ฏยฐCโ€”extreme stress where work should be limited. Since 2010, positive anomalies dominate. 300h = 12.5 days of danger. Itโ€™s important to focus on the sub-daily exposure.

Picture of an owlfly resting on a cream-coloured wall. The owlfy is quite hairy and holds its black and orange abdomen at an angle from the rest of its body. It has translucent wings and long, striped antennae with very obvious bulbs at the ends

Spotted this beautifully hairy #owlfly (Acmonotus incusifer) this week.

One of the Split-eyed Owlflies, it seems this isn't a commonly observed species. There are only 5 observations in #inaturalist with all of those in Western Australia.

We hope galaxias encourages more researchers to publish their data because they are already familiar with R or Python, so the barrier-to-entry is much lower!

Research data is so valuable for conservation, collected with robust methods & often in areas that are remote or difficult to access ๐Ÿง‘โ€๐Ÿ”ฌ

Once your data and metadata are ready, just run `build_archive()`, which will automatically build a schema file (meta.xml), zip and save your Darwin Core Archive to the parent directory.

You are now ready to share your ecological data with the world!
