This paper is about the Isle Royal Gray Wolf Population. This paper will discuss when the Gray Wolf first appeared there, their population when they were first studied, how the numbers have remained in check, the importance of the Moose population as it impacts the number of the Gray Wolves, their current population number and what has caused their population decline, what is being considered to help increase their population numbers, and finally conclude with what I believe should be done to resurrect their current population and why. To begin, the Gray Wolves first came to Isle Royale in about the year 1950 by walking on an ice bridge from Canada. Since 1958 the wolves have been studied and their population numbers recorded every year. Each winter to mid-January to early-March, the numbers of wolves are counted on Isle Royale. Since the studies first began in 1958, they have shown that Isle Royal will have an average number of about 24 wolves living in Isle Royale at any given time. (isleroyalewolf.org). Now that we have discussed when the Gray Wolf first appeared in Isle Royale and their population when they were first studied, we will look at how their numbers have remained in check. Over the course of studying the Gray Wolves for the last 50 years, it seems that the primary regulatory influence was believed to be food supply or social controls, or some

Nichols-Felan 2 combination, and high pup mortality in other wolf populations has been regarded as important in reducing their growth potential and the finding of an apparently malnourished pup on Isle Royal in 1964 suggests that food shortages during the pup-rearing season were of regulatory significance (isleroyalewolf.org). Now that we have discussed how the Gray

    One of many reasons the B.C wolf cull should continue is because the caribou population is intensely decreasing and wolves are the cause. The wolf population is not endangered and do not have predators which will affect the food chain negatively. In this case, shortening the wolf species would not impact their population greatly. For instance, in B.C 15 of 31 caribou herds are threatened (Government of B.C, no date) and the number will quickly increase if nothing is done to the wolves. If no action is taken place in order to save the caribou, it will be too late and canadas _______animal will soon be extinct. This important because having a steady, controlled cull saves both species from over exploitation and endangerment.…

    In order to help assess the impact of the challenging conservation work associated with red squirrels, grey squirrel management is being backed up by scientific monitoring and research. Other efforts are concentrating on the habitat of the red squirrel and attempts at designing and managing forests which would deter grey squirrels and encourage red squirrels. Buffer zones are being set-up around areas where red squirrels exist and there is continued monitoring and education. Another animal the pine martin has turned up and it has been observed that in the areas where this animal now roams there are fewer grey squirrels. This has led to the speculation that pine martens could act as a natural biological control and red squirrels will return and begin to flourish once again in these…

    Do you know how many gray wolves are left in North Dakota? There is no actual total because there are so few packs of gray wolves left. The gray wolf has resulted in a threatened species because predator-control is targeting them and destroying their habitat. Because they are supposedly killing too many livestock, predator-control is aiming towards gray wolves. The gray wolf is a threatened mammal in North Dakota. It is not commonly seen, but is usually mistaken for a coyote. They are being threatened all around North Dakota. Gray wolves appear in the state occasionally. As of 2013, it was arranged for the gray wolf to possibly be removed from the Endangered Species list. Currently, the population has rebounded since 1973 and is questionable…

    Usually this male and female are the only animals of the pack to breed. All of a pack's adults help to care for young In 1993, a study of the wolf-like canids found that there was a close kinship between domestic dogs, gray wolves, coyotes and Simien jackals but with a distance from the African wild dog and from the golden, side-striped and black-backed jackals. The domestic dog was an extremely close relative of the gray wolf, differing from it by at most 0.2% of the maternal mitochondrial Cytochrome b gene marker. In comparison, the gray wolf differs from its closest wild relative, the coyote, by about 4%. Therefore, the study concluded that the molecular genetic evidence did not support theories that dogs arose from jackal ancestors. The study proposed the hypothesis that because of the diversity of dog remains found in archaeological sites, that dogs may be derived from several different ancestral gray wolf populations. Later that year, the domestic dog Canis familiar is was reclassified as Canis lupus familiar is, a subspecies of Canis lupus in Mammal Species of the World.[26][76]pups by bringing them food and watching In 1999, a review of the scientific literature regarding the genetic origin of the dog proposed a number of hypotheses. The molecular data indicated that dogs have protein alleles in common with wolves, share highly polymorphic…

    one way to stop this is by forming a law on it being illegal to kill wolves. By this would prevent farmers from killing and being fined for doing so for example if a farmer where to kill one he will be fined a large price for killing the animal. Second way is by moving the wolf population away from farms and far away. By this if their still close to the kaibab but away from the farmers livestock will keep both sides happy. Third way is by adding hunters to kill of kaibab lowering the population. For this will make no need for wolves keeping them away from the livestock and both the over population problem and the killing of livestock will be solved.…

    Trophic Cascade Essay

    • 514 Words
    • 3 Pages

    After the wolves were reintroduced it began to restore the trophic cascade. The reduced browsing because of the altered behavior allowed increase in the recruitment of woody plants like Aspen (Populus tremuloides) and willow (Salix spp.) (Ripple and Beschta 2012). Without the elk decimating woody plants populations they were able to regenerate. This resulted in an increase in multiple species native to the park. These species included bison (Bison bison), beaver (Castor canadensis), and bears (Ursus arctos). The relative abundance and richness of 6/7 species of songbirds also increased because of the increased recruitment (Ripple and Beschta 2012). The wolves also have a positive effect on the age/sex structure. By concentrating on calves and older females they consistently eliminate the older sicker elk that are less suitable to survive. The wolves rarely prey on females in their reproductive prime or full grown males. The reintroduction has also had a positive effect on the bison population. The elk and bison share 80% of the same browsing food source. As elk are driven from their preferred browsing areas the bison are able to exploit the areas with the most nutritional…

    Wolves and humans have been coexisting for hundreds of years. Before Europeans conquered our vast country, wolves held a very esteemed place in Native American culture, as they were vital to forest ecosystems, and were often believed to be spiritual beings in many tribes (kidsplanet 1). As much as they were honored in tribal cultures, others feared them. Children’s fables often described them as “the big bad wolf” in stories such as Little Red Riding hood and The Three Little Pigs (kidsplanet 1). Settlers saw wolves in this way because they were a sort of competition, dwindling stock and wild game numbers (kidsplanet 1). Even into the 20th century, the belief that wolves were still a threat to human safety continued despite documentation to the contrary, and by the 1970s, the lower forty eight states had wolf populations less than three percent of their historical range, about 500 to 1,000 wolves (kidsplanet 1). In a book written by Bruce Hampton called The Great American Wolf, he states,…

    Gray Wolf Habitat

    Wolf reintroduction is only considered where large tracts of suitable wilderness still exist and where certain prey species are abundant enough to support a predetermined wolf population. The five last known wild Mexican grey wolves were captured in 1980 in accordance with an agreement between the United States and Mexico intended to save the critically endangered subspecies. Since then, a comprehensive captive breeding program has brought Mexican wolves back from the brink. Currently, there are 300 captive Mexican wolves taking part in the program. The ultimate goal for these wolves, however, is to reintroduce them to areas of their former range. In March 1998, this reintroduction campaign began with the releasing of three packs into the Apache-Sit greaves National Forest in Arizona. Today, there may be up to 50 wild Mexican wolves in Arizona and New Mexico. The final goal for Mexican wolf recovery is a wild, self-sustaining population of at least 100…

    “Wolves are the dogs that stayed behind.” The world is a cruel place. A thing that can be treasured in one instance can be a threat in the next. For many people, we stare at the natural world and see its rugged beauty and wish that we could captivate it for ourselves. The case is no different for our modern dogs. Bred from the “empty canvas” of a wolf, we’ve modified, altered, formed, transformed, reformed, and remodified wolves to be one of the closest companions we have still today: dogs. But through all of our perfecting and reshaping that we’ve done to our best friends’ closest ancestors, wolves have prevailed, echoing their famous legacy still throughout the world. Wolves, now in danger of extinction, are one of the greatest controversies…

    Wolf Vs Coy Wolf

    One area that really stood out to me is that a wolf pup will stay with its’ mother for up to 5 years before breaking off on its own to find territory. The new coy-wolves are now seeking their own territory after only two years of staying close to their mothers. These animals are maturing much quicker and able to adapt so quickly that they can now branch out twice as quickly as they otherwise would. This accelerated growth and development should also come as an alarm to humans and other species. As this group matures faster, they are no longer hesitating to reproduce as coy-wolves are now at a substantial…

    Over time Yellowstone National Park have undergone factors that have destroyed their wolf population. With this decline, or as others say habitual extinction, individuals began to understand the importance that these animals (1) had on a working ecosystem. In 1975 the wolf reintroduction process to Yellowstone began, however, it is still going on today due to it being such an extensive course of action.…
