The beetle Cucujus clavipes is found in North America over a broad latitudinal range from North Carolina (latitude approximately 35 degrees N) to near tree line in the Brooks Range in Alaska (latitude, approximately 67 degrees 30' N). The cold adaptations of populations from northern Indiana (approximately 41 degrees 45' N) and Alaska were compared and, as(More)
Conduction in the heart requires gap junctions. In mammalian ventricular myocytes these consist of connexin43 (Cx43). Hearts of non-hibernating species display conduction disturbances at reduced temperatures. These may exacerbate into lethal arrhythmias. Hibernating species are protected against these arrhythmias by a non-resolved mechanism. To analyze(More)
