Abstract: The electrocardiogram (ECG) reveals that heart chamber activation and repolarization are much faster in mammals and birds compared to ectothermic vertebrates of similar size. Temperature, however, affects electrophysiology of the heart and most data from… read more here.

DOI: 10.1093/icb/icy090
Abstract: All aerobic organisms are subjected to metabolic by-products known as reactive species (RS). RS can wreak havoc on macromolecules by structurally altering proteins and inducing mutations in DNA, among other deleterious effects. To combat accumulating… read more here.

DOI: 10.1126/sciadv.abb8458
Abstract: Herbivores have the highest representation of at-risk species in the present day, the recent past, and the late Pleistocene. As a result of their extensive home ranges and slow population growth rates, predators have often… read more here.
