Wolves: The Ecology Of Tundras

The tundra is by far the coldest type of biome, as it is known for its low temperatures, little precipitation, poor nutrients, and short growing seasons. Occurring primarily near the Arctic within the Northern Hemisphere, the soil may be frozen all year up to a few feet, which allows no tree growth. However, a few animals have adapted to these conditions. These animals include lemmings, hares, oxen, foxes, wolves, and more. Within the tundra biome there are two different types of tundra biomes, arctic tundra and alpine tundra.

Wolves have always been a symbol of the wild, free in spirit and roamers of the land. These animals are considered majestic and protectors of the wilderness. They have always roamed the western United States, although their population has fluctuated over time. Over the past 10 years wolf reintroduction into Yellowstone National Park has been a controversial topic to those of the United States. As of 1995, wolves have been reintroduced into the park. This has come with some strong opposition and yet has prevailed. The future of the wolf in Yellowstone park is now looking bright, although not certain since there still are those who want them banished again.

For the first time in 70 years, the howl of the Grey Wolf is being heard throughout Yellowstone Park (Sanders, 2000). In January of 1995, 14 wolves from separate packs in Canada were trapped and transported to Yellowstone. Once in the park the wolves were placed in one acre acclimation pens. In total there were three pens scattered across the northern portion of Yellowstone: one a Crystal Creek, another at Rose Creek, and the last at Soda Butte. During the wolves time spent in these pens they were fed winter kill, or road kill. The packs that were formed in these pens were released in the winters of 1995-1996 and also again in 1996-1997 for a second release period (Sanders, 2000). In 1995 fourteen wolves were released and in 1996 seventeen were released. In 1997 there were 64 pups born and since 1995, 33 wolves have died in the Yellowstone area.

During the 1940’s, wolves were exterminated from Colorado and few have come back since. As a result the ecosystem that we have in Colorado is somewhat skewed due to the absence of them. Many people think that wolves are a nuisance and would get in the way of the agricultural style that colorado has. However, wolves are considered a keystone species which means their “presence would reinvigorate the natural order” (clifford). For this reason wolves should be reintroduced into montezuma county. The reintroduction would greatly benefit and restore the balance of our ecosystem.

On May 3, 1995 female wolf number nine gave birth to eight puppies, the first wolves to be born in the park in nearly 70 years. The mother and pups were recaptured and taken back to the acclimation pen, until the pups were weaned (Sanders par. 15). The reason for this recapture was because at this time, this wolf and her eight pups counted for almost 50% of the park’s wolf population. Since this time there have been no other human interventions preferring to let nature take its course on the population.

When the wolves were first reintroduced, having 30 equally distributed breeding pairs was enough to constitute a success. A breeding pair is defined as an adult male and female wolf raising two or more pups in a year, where the pups are born between April and May and then raised till December 31. With the reintroduction of the gray wolf, a recovery population goal had to be established. That was the goal of the United States Fish and Wildlife Service (USFWS) for the recovery of the wolf population for the northern Rocky Mountains. Wolf numbers needed to be maintained at this level for at least three consecutive years. According to the USFWS 2002 was the third year where there had been at least 30 breeding pairs throughout Wyoming, Montana, and Idaho. After 2002, these wolves are still multiplying and the population continues to soar, even at this very moment.

The thesis of this article is that wolves, once endangered, have come back and started to flourish causing mixed feelings for locals and biologists. Wolves were once hunted because one, to protect livestock, and two, they were seen as pests and/or vermin. The government then put wolves under the endangered list to try to save them. Since then, wolf populations have multiplied.

The gray wolf is one of the world’s most well known and well researched animals with more documentation on them than any other wildlife species. It is a canid whose main habitats are in the wilderness of remote areas in North America, Eurasia and North Africa. It is the largest member of the wolf family, usually weighing between 70 and 120 lbs, and closely resembles in general appearance and proportions to a modern day breed of dog known as the German Sheppard, although they typically have a larger head, narrower chest, longer legs, straighter tails and bigger paws. The narrow chest of the gray wolf allows for swift and efficient movement through the common elements of their environment such as snow, brush and other conditions. Their larger heads indicate their higher level of intelligence and their large paws, webbed with fur aid in movement across mud and snow. The colour of a gray wolf’s fur lives up to its name and is predominantly a mottled gray although the gray wolf can also have fur that is nearly pure white, mixes of red, brown, or black. Being very social animals, gray wolves do mostly everything in packs of 2 – 15 animals; living, traveling and hunting. They can hunt and feed off smaller game, yet with their large pack size, they can work collectively to bring down large game such as deer, moose or bison. There are 37 recognized subspecies of the gray wolf in total ranging across six continents with familiar names that one

Red wolves are very similar to the coyotes. As their name name suggests the have red coat but also a little brown mixed into it. They are the smaller and leaner version of their cousin, the grey wolf. They are native to the southeast region of North America. Red wolves are mostly found in forest and swamps but can survive mostly anywhere in the southeast. They are a carnivorous species and their diet ranges from small rodents to white tailed deer. If they can not find anything else they have been to eat berries and insects to survive. Red wolves breed once a year during January through February. They

Long before the settlers started to make the United States their home, “American Indians lived long beside the Gray Wolf before settlers started to come here.” (Rowe, Mark) The wolf is native to the North American continent and has been inhabiting its land for centuries. It is a canid species, or member of the canine family and is a cunning, smart, fast, and sly animal. Gray wolves range in color from black, brown, gray, and white and also look like a grown German Shepherd. They are well known for traveling in family sizes from 7-9 wolves, led by the alpha male and have a mate. They are a fierce animal that has been researched extensively because of their unique qualities and that they are near extinction.

Gray wolves. To some, these creatures are monsters, harbingers of death and destruction. To others, they are simply misunderstood creatures, protective of their family and their pack. However, what either side does not know is that these creatures play a greater role in their ecosystem than one human alone could understand. Grey wolves are one of thousands of different keystone species- species of organisms that have a large effect on the health and stability of a particular ecosystem. But they are also on the brink of extinction. The over hunting of these creatures in the 1900’s has lead to a severe decline in their population throughout the U.S., creating a ripple effect in the ecosystems in which they reside in. Luckily, reintroduction

A single pack may contain animals that are black, shades of gray-brown, and white. Wolves in the heavily forested areas of eastern North America are more uniform in color. They are often a grizzled gray-brown like some German shepherd dogs. This color variation is a good example of natural selection, which enables those animals best suited to a particular environment to survive. On the arctic islands, where much of the ground is snow-covered for at least nine months of the year, being white is a distinct advantage, so wolves in the Arctic may be nearly white. In the mottled grey, green, and brown world of the eastern forests the normal coat of the wolf is an effective camouflage. As a wolf moves stealthily, or rests, it blends into the background and is hardly seen. Wolves in the Arctic have extremely dense under-fur, which insulates them against rigorous winters. Another adaptation to environment is their habit of hunting in packs, or groups, which enables them to kill large animals.

Wolves in the Upper Peninsula have been a hot topic for many of years, especially the hunting and trapping of them. I think people pro wolf are afraid that making it legal to hunt them would eventually make them an extinct animal. This shows us a type of supply and demand, where the supply is the wolves in their natural environment and the demand is where the people live and want to live in harmony with the wolves.

The raven, eagle, and crow populations are growing due to the leftovers of the wolves.

After years of selective breeding and taming, the hunters finally came across some wolves that were able to listen to commands and do what they were ordered to do. These wolves did not look like the first ones with which humans came into contact. Their size, coloring, senses and even the length of their coat or swimming ability reflected the environment in which they lived. These environments could have ranged from anything since hunters do not stay in one place for very long. These wolves probably did not reflect their gray ancestors much anymore. The color of their coat could have become brown, black, or even yellow depending on where they were taken. Their size could have been affected, too, depending on how the hunters had used them- they could have shrunken to the size
