This is an endemic from Mauritius that I thought I would have to leave the island without seeing: the Mauritius ornate day gecko. I managed to find quite a few in the end and I think that their upright posture complements their smiley face perfectly!

I am looking for a PhD student to join my new Socio-Eco-Evo group, hosted in Katie Peichel's Evolutionary Ecology Division @ University of Bern. We're offering a fully funded 4-year position, studying social plasticity and behavioral adaptation among stickleback in Greenland. Please share around!

Another endemic from Mauritius: the Mauritius kestrel. The only bird of prey on the island. I had never been that close to a raptor in the wild!

I have recently visited Mauritius, where I was constantly looking for animals that I had never seen before (both in the water and on land). The pink pigeon is one of the few endemic birds that you can see there. They were almost extinct in the '90s and are still pretty rare in the wild.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

It was a pleasure talking to Mary about our apparatus to take fish cognition research into the wild! 🐟🧠 Read it on Psychology Today ⬇️⬇️ with @kotrschal.bsky.social and @amydeacon.bsky.social

How does predation shape evolution? We tested this with guppies, exposing them to real predators over 3 generations. Survivors evolved fast: bigger females with earlier broods, males with shorter tails and gonopodia. But... www.science.org/doi/10.1126/...
