Normal resting heart rate. It is important to identify whether your heart rate sits within the normal range. If disease or injury weakens the heart, the organs will not receive enough blood to function normally. The United States National Institutes of Health (NIH) have published a list of normal resting heart rates.
There are currently two recognized species of wolves, the Canis lupus, or grey wolf, and the Canis rufus, or red wolf. These are two of the species that comprise the Canidae family in the Carnivora order. The red wolfâs Genus name, Canis, is Latin for dog.
Subspecies of gray wolves in North America include the Arctic wolf (Canis lupus arctos), northwestern wolf (Canis lupus occidentalis), Great Plains wolf (Canis lupus nubilus), Mexican wolf(Canis lupus baileyi) and the eastern timber wolf (Canis lupus lycaon), which is debated by some as a distinct species, the eastern wolf (Canis lycaon).
