I had great time presenting our poster (@jule_neu, @ClocksEvolution) at #dzg23 on transcriptomics of circalunar clocks. Thank you all for great discussions. @BiologyDzg

The marine insect #Clunio can sense the rhythm of the tides based on the agitation of the water. But some Clunio populations are numb. We just published a study on the genetic basis of being numb in #PLOSGenetics: dx.plos.org/10.1371/journal.… @Dusica_bio @MPI_EvolBio @_K_E_C

Genetic analysis of a phenotypic loss in the mechanosensory entrainment of a circalunar clock

Author summary Biological clocks allow organisms to synchronize their physiology and behaviour with their environment. A key part of this mechanism are reliable environmental cues that play a role in...

Biological clocks are critical for organisms. Patrick Emery, PhD, vice chair and professor of neurobiology at @UMassChan, uses the crustacean Parhyale hawaiensis to interrogate genomics of circatidal rhythms: direc.to/joS6 @LabEmery @NeurobioUMass @MBLScience @Parflyale

Gene linking circadian and circatidal rhythms is discovered in tiny crustacean

Scientists at UMass Chan Medical School and the Marine Biological Laboratory at Woods Hole have identified the first gene to play a crucial role in regulating circatidal behavior in the crustacean...

Like the day night cycle, tides are a regular occurance that creatures have evolved to anticipate. But how, and what might the genetic basis of this be? Here, using CRISPR, @LabEmery find a circatidal clock role for the traditionally circadian Bmal1: cell.com/current-biology/ful…

Behavioral circatidal rhythms require Bmal1 in Parhyale hawaiensis

Animals living near the coastline rely on circatidal clocks to predict the tides. The mechanism underlying these timers is not known. Kwiatkowski et al. introduce P. hawaiensis as a model to study...

In the marine midge Clunio marinus, sympatric ecological population divergence with gene flow is based on at least four genetic loci, which partially overlap with large chromosomal inversions.
