Heart beating tango of mussels and temperature

Some exciting preliminary results from the Coopenor field work in the White Sea shows both littoral and sublittoral mussels having a heart beat well synchronized to the ambient seawater temperature. The heart beats increase gradually with increasing temperatures from March to June/July, and is on the way back down now in the winter.

I mostly noticed that my colleague Igor has a better chance to go for a swim at its sampling site that we do in Tromsø…3 to 5 degrees more in the White Sea do a huge difference for us!
