In this section, the algorithms and techniques used in the design of the proposed approach will be introduced. 2.1. Grey Wolf Optimizer Grey wolf optimizer (GWO) is an optimization algorithm simulating the hunting and leadership mechanism of gray wolves and it is introduced by Mirjalili et al.21. An overview about this algorithm is given below. Main concepts and inspiration . Grey wolves are considered as apex preda- tors, which they are at the top of the food chain. Grey wolves prefer to live in a group (pack), each group contains 5-12 members on average. All the members in the group have a very strict social dominant hierarchy. The social hierarchy consists of four levels as follow. The rst level is called Alpha ( ) The alpha wolves are the leaders of the pack …show more content…
The alpha wolf is considered the dominant wolf in the pack and all his/her orders should be followed by the pack members. The second level is called Beta ( ) The betas are subordinate wolves, which help the alpha in decision making. The beta wolf can e either male or female and it consider the best candidate to be the alpha when the alpha passes away or becomes very old. The beta reinforce the alpha's commands throughout the pack and gives the feedback to alpha. The third level is called Delta () The delta wolves are not alpha or beta wolves and they are called subordinates. Delta wolves have to submit to the alpha and beta but they dominate the omega (the lowest level in wolves social hierarchy). There are di erent categories of delta as follows Scouts. The scout wolves are responsible for watching the bound- aries of the territory and warning the pack in case of any danger. Sentinels The sentinel wolves are responsible for protecting the pack. Elders The elder wolves are the experienced wolves who used to be alpha or beta. Hunters The hunters wolves are responsible for helping the alpha and beta wolves in hunting and providing food for the
betas are subordinate wolves that help the alpha in decisionmaking or other pack activities. The beta wolf can be either
There are two factors that play a role in making a dog a pack leader. Those two factors are the hormones and the level of energy. A pack leader is usually male because of the hormones. A strong pack leader must have a good level of energy because they must be able to hunt for food and look for water. Caesar goes further on in his article to talk about how “a dog is born to be a follower.”
It is a kind of grey wolf, though is no longer thought to be a distinct subspecies, it is the least threatened of all grey wolves and its subspecies populations as they live in isolated regions that rarely bring them into contact or conflict with man.
of the wolves and finds that they are more than the savage and merciless hunters
The wolf is the largest member of the dog family Canidae, making it a real pest if it goes unchecked in agricultural systems. The wolf is one of the most efficient and effective predators in this region, preying on large ungulates; elk, deer, big horn sheep, moose, and even bison and cattle; however they will eat small mammals if there is no other food source available. Prior to 2002 estimates of the loss of livestock due to wolves were 19 cattle and 68 sheep, however in 2002, 33 cattle, 71 sheep and 1 dog were confirmed killed by wolves (Wyoming Wolf Management Plan, 2003). These kills are significant...
Wolves used to thrive in the western United States. There was ample game to hunt and plenty of places to live and wander. Until people moved in, wolves were settled. As European settlement expanded to the west, it began to take its toll on the wolves and their habitat. Clearing of the forests came first, which was then accompanied by significant over-hunting in this area (Noceker). Slowly wolves became concentrated into smaller and smaller areas in the west. Finally, they were assumed to be bothers to the ranchers and farmers and maybe a threat to those people who lived in the area.
Hypotheses of the Effects of Wolf Predation Abstract: This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies. It was concluded that the predation limiting hypothesis fit most study cases, but that more research is necessary to account for multiple predator - multiple prey relationships. The effects of predation can have an enormous impact on the ecological organization and structure of communities.
Thus, the question is what makes a leader a leader. For example, back in the early days of homosapian they were so immensely surrounded by danger everywhere either the whether or carnivorous animals harming the very existence of the homosapian race. This caused the homosapian to become social with fellow homosapians which resulted in many pros and lessened the cons for example, a pro would be an increase in safety causing comfort a circle of trust. An environment in which the homosapian could prosper in a calmer as well as trustful manner due to these leaders would prosper those who would stay up in the night to spot danger to worn the rest of a tribe.

Not many people know about the arctic wolf, it is the snowy white version of a wolf. They have a really big appite when it comes to eating. They most only eat one meal a day and eat up to 20 pounds in that one meal. They are mostly carnivores; they mainly eat big animals like the caribou and the musk ox so they can feed themselves and the whole pack (Arctic/Antarctic: The Arctic Wolf). People eat up to three meals a day, but wolves can go up to days with out eating a single thing (Arctic/Antarctic: The Arctic Wolf). When wolves are hunting they have to be able to have a plan to catch their food. Wolves would get all the pack members that are hunting to surround the animal, and pounces on them. One bit to the neck and the animal would be dead. When they are eating they will eat everything, like the meat, shin, fur and bone (Arctic/Antarctic: The Arctic Wolf). Also Arctic wolves can live up to 20 years in captivity, while they can only live 7- 15 years in the wild (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most prettiest and unique types of wolf. When Arctic wolves are pups t...
Wolves generally live in packs. A typical wolf pack would include a leader male and female wolf (alpha wolves), their pups, and possibly several other non-breeding adult wolves. Packs can vary from 25 square miles to 500 square miles, depending on the availability of prey. Within a pack, only one pair of wolves mate. This pair is known as the “alpha pair.” The female wolf only goes into heat once a year in January or February. If she becomes pregnant, she wil...
Sometimes they even hunt moose. Their sense of smell is superior. Wolves hunt in packs all male to be exact. Wolf packs are mostly led by the parents of the wolves and some other wolves with the parent wolf to join their pack for hunting and killing their prey. The Gray Wolf can also run as fast as 31 - 37 MPH which makes them really good hunters. And they have been seen viciously attacking people. Unlike some animals wolves don’t hibernate so they have to hunt all year. Wolves also tend to mate in the early spring as well. Then before you know it the female wolf has babies some time during the winter, and their babies also have to eat.
Canis Lupus, the Latin term for the “North American Wolf”. A meat eating mammal with the capability of weighing up to 180 pounds and reaching a height of sixty-three inches, the wolf is easily the largest member of the canine family. Over 500,000 wolves once lived in harmony, roaming the Northern Americas alongside the Native American tribes and the rest of the ecosystem. Wolves live in packs, a pack essentially being a family. While the average size of a pack is six to ten, the largest confirmed pack recorded in North America can be found in Yellowstone National Park where the “Druid Pack” numbers thirty-seven strong and counting. There have been alleged reports of a pack that attacked a small Russian town killing thirty horses in just four days. This pack numbered up to almost 400 members. Animal experts remain suspicious due to the fact that this number is almost fifteen times the size of an average sized pack. Wolves heavily rely on their pack. Every member of the pack has a specific job that benefits the pack, without the pack, death would be almost imminent. The pack is set up as a hierarchy, with an alpha male and an alpha female. The alphas get the best of everything, the best part of the kill, the best sleeping spot, and the breeding rights. When hunting, one member will scout ahead and will determine the weakest member of the herd. Once determined, the rest of the pack will chase the animal down and either takes it down on the run or chase it until it tires out. Unlike many predators in the animal kingdom, wolves eat their prey alive. While wolves are known for their spine tingling howls, the howl is not the only way they communicate. “Wolf Language” so to speak, consists of many grunts, snarls, growls, yips, and whines....
However, the hunters would not keep all of the wolves that grew up from the cubs they had. Keeping a wolf that became overly aggressive towards them, or if it had little practical use, would have been both pointless and dangerous to their group. They most likely would have killed those types of wolves or left them behind to fend for themselves. The hunters would have chosen semi-tame wolves and those with the most desirable traits and abilities and bred the two together, repeating the process until what resembled a dog today. The first bones found which ...
Let me tell you something. In 1970, Gray Wolves used to have a population of 250,000. But now due to mass wolf hunting, the numbers are down to 500. Hello everyone. Today, I’d like to speak on behalf of the Wolf Conservation Center about the importance of wolves, and why they should be protected. Wolves are too often a misunderstood creature, instead of showing fascination, we always fear them, which is the exact opposite of what we should be doing. The society of wolves is just like ours, sorted by ranks, defined by confidence, and full of emotions. We are more like them than we think. Except they are being hunted, and we are not. In many parts of where they range, all types of wolves are being persecuted for killing livestock. As a result, humans have been killing wolves for years, because of us, their numbers are decreasing by thousands.
