Lisa’s paper on ion balance and cardiac performance in crabs exposed to heat stress titled “Paralysis and heart failure precede ion balance disruption in heat-stressed European green crabs” is now published in the Journal of Thermal Biology!
“Acute exposure of ectotherms to critically high temperatures causes injury and death, and to find out which physiological mechanisms set the thermal limits, we need to comprehend in what order the physiological perturbations occur. In this paper we found that extracellular ion balance is lost when crabs are exposed to heat stress, but that this loss only follows AFTER the crab is paralyzed, and cardiac performance is compromised. Accordingly, loss of ion balance does not cause paralysis, and this loss might instead be a consequence of tissue damage caused by failure of other physiological systems.”
