Species are arranged in descending order of peak I_Ca density within high (18-25°C) and low (4-5°C) acclimation temperatures. All peak I_Ca measurements are from patch-clamp experiments on isolated ventricular cardiomyocytes recorded at acclimation temperature (unless otherwise indicated below). Results obtained in the present study are bolded for emphasis. Results are means ± SEM. ND, Not determined. Species are: Squalus acanthias, spiny dogfish; Danio rerio, zebrafish; Dallia pectoralis, Alaska blackfish; Carassius carassius, crucian carp; Trachemys scripta, red-eared slider turtle; Scomber japonicas, Pacific mackerel; Oncorynchus mykiss, rainbow trout; Thunnus orientalis, Pacific bluefin tuna; Trachemys scripta scripta, yellow-bellied turtle; Varanus exanthematicus, Varanid lizard; Acipenser baerii, Siberian sturgeon; Lampetra fluviatilis, European lamprey; Lota lota, burbot; Perca fluviatilis, European perch.
