Things that Darwin hated, a 🧵

But I am very poorly today & very stupid & hate everybody & everything. One lives only to make blunders.— I am going to write a little Book for Murray on orchids & today I hate them worse than everything

2 year position (Indiana, USA) studying the Neurobiology of insect welfare in the Barrett lab. Sort of a pre-doc position for someone with a BSc (and ideally) MSc in a relevant discipline. An excellent opportunity to gain (paid) research experience!

This grass moth is often invisible in still frames, but easy to see in motion. BehaveAI can use this motion to track tiny & camouflaged moving objects in complex scenes. Its semi-automated annotation workflow also means this moth-tracker took only an hour to make.

How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

The reshuffling of genomic variation from multiple origins is an important contributor to phenotypic diversification, yet insights into the evolutionary trajectories of this combinatorial process and ...

Chickening out: Why some birds fear novelty
The largest-ever study on neophobia, or fear of novelty, has discovered the key reasons why some bird species are more fearful of new things than others.

What an amazing group of 🐛

@anurag-asclepias.bsky.social has written about his encounters with Euchaetes egle: how the caterpillars handle latex, & even caused him a nasty rash from their pupal hairs. Such small & formidable natural chemists!

Cool! I have milkweed tussock moths (Euchaetes egle) here in my yard in Michigan, USA. As I understand it, they sequester glycosides from the milkweed and, as adults, produce calls that advertise their unpalatability to bats. Interesting clade!

🍄 FLY AGARIC (Amanita muscaria)

This fairy-tale fungus forms mycorrhizal partnerships with trees, trading nutrients for sugars underground. Its red & white cap signals potent compounds (ibotenic acid & muscimol) that can cause hallucinations and delirium.

Strictly for admiring, not nibbling!

Calliteara pudibunda, the pale tussock moth caterpillar. Brilliant yellow tufts and an ultra-black stripe – a striking warning. When disturbed, it curls into a conker-like ball. Those hairs are likely irritating to the skin, a fine example of visual and chemical defence.
