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:

Curious how the #moon is perceived, controls #development, and may drive #speciation in a #marine #insect?

If you want to know more about #circalunar #clocks, the following might also be interesting:

(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.
