We have a new #preprint on #lunar #reproductive #timing as a #magictrait in #speciation www.biorxiv.org/content/10.6... with former PhD students Alexander Jacobsen 🧪💻 Runa Ekrem 🦟🌊 🙏 Big thanks to both for the great work! #EvoBio #barriers #Chronobiology #circadian #MarineEcology

Full moon and new moon strains from Roscoff differ in lunar reproductive timing (A). Genotyping of 11 divergent loci (B) in 797 field-caught individuals shows that thetwo timing strains are distinct genetic entities (C).

We had a visit by former #postdoc @juleneumann.bsky.social last week. She presented her current work on ⏰ #clocks & #crabs 🦀 @aberuni.bsky.social, including the her amazing high-throughput #phenotyping setup. Good to have you #home for a while! @mpi-evolbio.bsky.social #marine #chronobio

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:

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! @kokkonut.bsky.social @lottedevries.bsky.social #Evobio #MarineEcology #Ecology #Modelling #Chronobiology Picture by Solvin Zankl

(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. (1/5)
