Jule, thank you for all your contributions to the group - and to the institute - over all those years! All the best for the next steps!

There is also a really nice thread by @kokkonut.bsky.social giving more details to our two joint papers on how #timing by the #moon allows #coexistence in a #marine #midge:

A big thank you to everyone involved in this!
It was great fun!

Coexistence by Moonlight: How Midges Divide Time and Space How can different ecologically specialised populations of the same species—so-called ecotypes—coexist within the same habitat and even evolve into distinct species over time? This fundamental question...

How an Insect Converts Time Into Space: Temporal Niches Aid Coexistence via Modifying the Amount of Habitat Available for Reproduction Temporal niches do not automatically promote coexistence. Combining field data and modelling, we show that in the marine midge Clunio marinus, sympatric timing strains, which reproduce during full mo...

In the second study we found out that differences in #lunar reproductive #timing of the adults can lead to spatial separation of the larvae, which in turn allows coexistence.

In the first study we showed that #coexistence of #Clunio strains which live in the same habitat, but differ in #lunar reproductive #timing is not easily explained.

Happy to share that we just published two papers from an exciting and fruitful collaboration with Hanna Kokko, involving Runa Ekrem, Alec Jacobsen and Lotte de Vries!

The #marine #midge #Clunio lives for only one low #tide
and its emergence follows the #lunar #cycle!

On the Essential Principles and Practice of Circadian Biology: A Road Map – Simple Book Publishing Circadian Biology is about the adaptation of life to our rotating world, to the Earth’s 24-hour rhythm of day and night. Not surprisingly, the field has attracted considerable popular and scientific ...

Interested in (studying) biological #clocks?

Here is a brilliant and concise introduction to the field, focussing on #ciradian clocks, and stressing the #adaptive nature of clocks.

A question to the #Naturalists 🌿 out there:

Have you ever met this strange critter at the #beach?

You should be able to find Clunio species on rocky #coasts around the world – but only around full #moon and new moon!

(5/5) #Research
Our group studies these timing adaptations with #genomic and #molecular tools, aiming to decode the unknown lunar clockwork. We also explore the role of #biological #clocks in #ecology, #evolution and #conservation.

(4/5) #LocalAdaptation
But the tides differ along the coastline. Therefore, the lunar clock of Clunio populations from different places needs specific adaptations to the local tides.

(3/5) #Lunar #Rhythm
… and then time these hours to the lowest low tides. These tides always occur at full and new #moon. Clunio has an internal timer, a so-called #circalunar #clock. It enables the midges to predict #moon phases and allows adults to only emerge at the right #time.

(2/5) #LifeCycle
Clunio’s long-lived larvae prefer to be submerged and therefore settle in the lower parts of the intertidal zone. However, the adults need these regions to be exposed for egg-laying. The solution was to reduce adult lifespan – and thereby mating and egg-laying – to a few hours …

#Moonstruck #Midges: Introducing Clunio marinus
#Clunio is a midge and a truly #marine #insect. You can find it on the #European #Atlantic #coast in the #intertidal zone. This is the region between the low #tide and high tide, alternating between marine and terrestrial conditions.

This week, the Clunios @clocksevolution.bsky.social had the pleasure of hosting @clairemerot.bsky.social and hear about her awesome research on the role of inversions in adaptive evolution! We explored the baltic sea and found wrackbeds full of seaweed flies. Thanks again for visiting us, Claire!

🧬 Rethinking Cooperation in Biology?

New study suggests that natural growth differences – not just strategy – matter big time for cooperation in nature.
Turns out, yeast don't need to be strategic.

A very nice study from our institute @mpi-evolbio.bsky.social @avezyrakis.bsky.social

Note the press release: "It’s a charming lesson from the humble house mouse: sometimes it’s not the loudest or boldest who breaks through — it’s the one who keeps coming back."

Does this also apply in science?

A big thank you to the organizers of this workshop!
Great speakers, great atmosphere!
We enjoyed it a lot!
