Our current follow-up #modelling study with @gokhalecs.bsky.social, former colleague @mpi-evolbio.bsky.social, suggests that larval competition for space can actually drive the evolution of divergent reproductive timing, aka #allochrony, which results in spatial separation and reduced competition.

Previous work with @kokkonut.bsky.social (tinyurl.com/28hxwree) showed that #sympatric Clunio strains reproduce AT full #moon or BEFORE new moon. During these times low tide levels differ, placing the eggs & larvae at different elevations. This spatial separation allows #coexistence of the strains:

How can larval #competition for space, adult #reproductive #timing and the #tides interact to produce different timing strains, aka #chronotypes, of the marine insect #Clunio?

Could humans and AI one day form a single “evolutionary individual”? Researchers at the Max Planck Institute for Evolutionary Biology raise this question in a new publication exploring human–AI interdependence.

Years of work distilled to 1 minute:
Our recent paper with @kokkonut.bsky.social has made it to #youtube !

The AI illustrations do not look anything like real-life #Clunio - but they are captivating.

And the scientific content is accurate and well explained!
