Wolf Species and their Sub-Species


                According to the found information I put together an excel sheet to display the three main wolf species as well as other wolves found throughout the world. I put the sub-species underneath each of the three main wolf species I found within websites that had been updated recently, instead of from 2003. The three main species of wolf found consisted of North American Gray Wolf, Eurasian Gray Wolf and Red Wolf. Other items that can be found within the excel sheet is the information in knowing if the sub-species of that wolf is alive or extinct. Underneath the category of the North American Gray Wolf sub-species I realized there was the dingo as well as the domesticated dog, I had them bolded to let my viewers know that some biologist’s do not count this sub-species, but I wanted to keep them within the excel sheet because they are part of the canine family.
                The North American Gray Wolf is the largest of all the canine family. Their colors vary from salt-and-pepper gray, black or all white. These wolves resemble the German shepherds they are an ancestor of the domesticated dog. Their diet consists of large hoofed animals such as deer, elk, moose and caribou. It is remarkable because these carnivores have also been known to consume beaver as well as rabbit and other small mammals. These wolves are scavengers and usually pillage off animals that have died due to such causes as disease or malnourishment. Common threats Gray wolves encounter is death from the quarrel between people due to their livestock losses.  These people are known as, Ranchers. Wolf predation is very slim as well as an uncommon threat to livestock, though Ranchers still put the blame on wolves. Wolves that are caught in the act of attacking or killing livestock are killed. Defenders of this beautiful creature are desperately trying to fix the problem in a different manner rather than just butchering the wolves.  Some of the possible ideas to stop wolves from attacking livestock and intern stop the killing of wolves are to try putting up fencing around the livestock, more lighting in areas that are dark, an alarm system or removing the feeble of the livestock that may attract the scavenging wolves. Most of the threats linger in the myths of wolves and the fear it leaves in people of this misunderstood creature, the wolf. Wolves are an essential part of the ecosystem and many defenders as well as conservation organization will not rest until this animal may roam freely once more.
                The Eurasian Gray Wolf survived and lives in North America as well as some parts of Europe and Asia. Several of the sub-species of the Eurasian Gray Wolf did at one point live throughout Northern Europe and Asia as well as some of the southern parts of India and the Arabian Peninsula. About one-third of wolves have been reduced in areas throughout the world though this wolf, the gray wolf survived. They are widely spread throughout the world and the numbers of this particular species is increasing. The gray wolf is stated to be the least of the wolf to be concerned about because they are making a comeback. In speaking in terms of the wild populations of the Eurasian Gray Wolf they are found most commonly throughout central Asia which includes Russia, Kazakhstan and parts of the Soviet Union. In this area there are 90,000 wolves and in Mongolia there are more than 10,000 wolves present. Every year many wolves are killed in the country Russia for their fur due to the fur trade as well as the ongoing conflict with humans. The main conflict between humans and wolves is due to the loss of Ranchers livestock from wolves.  In Western and Eastern parts of Europe wolves are slim in finding in these areas including Spain, France, Germany, Scandinavia, Italy, Greece, Poland, Romania and Croatia. Due to the protection placed by the United States government since the 1970’s this has allowed the populations in Europe to come back into play decently.
                The Red Wolf is not as the Gray Wolf it is much smaller with being a slender breed of wolf. The coloring of the Red wolf is gray-black with an addition of a reddish cast that gives this wolf its name. Their diet consists of rodents or small mammals such as rabbits. These wolves have been known to eat berries and if able to they will consume deer.  These wolves were hunted to the point of extinction; though the U.S Fish and Wildlife Service decided to catch and help breed 20 pure red wolves in captivity in the year of 1980 to help the population regain its numbers. In the year 2007, there were about 207 red wolves in captivity at 38 different captive breeding services. Due to these programs it has helped more than 100 red wolves to be able to live peacefully in the wild. Red Wolves are found through the parts of the southeastern U.S from Pennsylvania to the sunshine state, Florida and all the way to Texas. Wild populations of red wolves roam more than 1.7 million acres within the northeastern North Carolina, which includes a national refuge, called Alligator River National Wildlife as well the refuge Lakes National Wildlife. Red Wolves are shy, guarded and either hunt unaided or in small packs. Red Wolves are complex individuals when it comes to breeding; they form pair-bonds for life. The number of wolves in one pack depends on how abundant their prey is because if there is slim food then some of the pack may die off due to starvation. The places that red wolves pick for dens are usually in hollow trees, stream banks and sand knolls. These wolves reproduce in the late winter and their gestation period is about 60-63 days. Red Wolves are able to have the minimum of 2 pups and are able to have maximum of 8 pups. The threats that attack this species of wolf are human developments, harsh weather conditions, vehicles, and of course illegal killings. Interbreeding that happens between coyotes and red wolf populations is a constant threat due to the species because recovery of red wolf is not taking place rather a new and unstable breed is being made.
