My presentation is about the snowy owl the biome it lives in and the plant I chose to present.
The biome of the snowy white owl is the tundra. Snowy owls rely on prey populations, such as lemmings, that change a lot over time. As a result, snowy owls go wherever there is plenty food resources at any time. Normally, snowy owls remain in the northernmost parts of Alaska, Canada and Eurasia. But in seasons when prey is hard to find in the northern part of their range, snowy owls move further southward. For example, during the years of 1945 through 1946, snowy owls made a widespread, coast-to-coast movement into the southern parts of Canada and the northern parts of the United States. Then in 1966 and 1967, snowy owls moved deeply into the

Pacific Northwest region. These migrations happened at the same times as declines in the lemming population. Lemmings feed on plant life, but if there is a shortage one year, the number of lemmings surviving decreases. The lemming is the primary food source for the snowy owl, and with lower numbers of lemmings to feed on the number of owls drop too. The tundra biome has very cold temperatures with an average winter temperature of -30 degrees Fahrenheit. The tundra is the coldest of all biomes on Earth and has the least amount of different plant and animal life. Tundra got its name from ‘Tunturia’ a Finnish word that means “treeless plain” or “barren land”. There is very little rain. Because the soil, named permafrost, is always frozen, plants only grow for a short period of time. Trees cannot root in permafrost and with the lack of precipitation throughout the year or sunlight during the winter, the small amount of plant life found in the tundra lies dormant for many months of the year. Under these conditions, the animals that live in the tundra have adapted to live in the extreme conditions. Animals found in the tundra biome include caribous, lemmings, voles, squirrels, arctic hares, arctic foxes, wolves, musk oxen, brown bears, polar bears, killer whales, beluga whales, sea lions, seals, walruses, ermines, reindeer, moose, snowshoe rabbits, moths, grasshoppers, salmon, trout, cod, pikas, marmots, mountain goats, beetles, sheep, elks and butterflies.
Tundras are also home to a variety of bird species, including arctic loons, long-eared owls, rose breasted grosbeaks, bald eagles, golden eagles, gyrfalcon, king penguins, rockhopper penguins, emperor penguins, snow gooses and snowy owls. Land animals found in the tundra biome, such as the musk ox, generally have thick fur, hair, fleece or wool to provide insulation against the cold climate. Some animals that are unable to withstand the extremely cold temperatures only live in the tundra during summertime. Migratory birds, such as ravens, snow buntings, falcons, sandpipers, terns and snow birds, leave the biome during the winter season. Bears also hibernate and sleep during wintertime to escape the …show more content…
cold. The tundra covers about a fifth of the earth’s land surface.
There are two major tundra biomes: the Artic Tundra and the Alpine Tundra. The Artic tundra is located around the north-pole in the northern hemisphere. This biome has temperatures of about 36 degrees Fahrenheit in the summer and about -30 degrees Fahrenheit in the winter. Bogs and ponds are common as a result of constantly frozen surface moisture and melted permafrost. As a result of these extreme conditions, tundra animals develop adaptations to survive the harsh environments. Plants in the Artic Tundra are short and grow closely to each other. Examples include mosses, heaths and lichen. They are adapted to perform photosynthesis even in the freezing conditions. The Alpine Tundra is also very cold, located on top of high mountains, often with very few trees and very little vegetative cover. They are icy for a larger part of the year. The tundra gives a clear picture of a food chain because of a small variety and population of animals and plants the snowy owl has a bird eye

The Pacific Northwest is perhaps most commonly known for its awe-inspiring old growth forests that have been gracing the land for hundreds and hundreds of years. The land in British Colombia, Canada, Washington state, Oregon, and parts of Northern California are the only areas in the world where these forests exist. One of the most unique and amazing inhabitants of this age-old forest is the Northern Spotted Owl. The Northern Spotted Owl has been on the endangered species list for over ten years now. The Northern Spotted Owl can only be found in these old growth forests. The northern spotted owl requires many acres old forests to survive, due to its scarce food supply. They are very sensitive to their habitat, and simply cannot survive in any other environment. These owls, as well as the forests have been disappearing at an alarming rate due to the immense logging industry in its area.
The Hudson Plains ecozone, in northern Ontario and parts of Manitoba and Quebec, is an area of wetlands. The climate is generally cool. The northern part of the ecozone is full of shrubs, but no trees, and areas farther south contain forests. Wet have vegetation such as moss and lichen and also some trees like willow, tamarack and black spruce. More northern, drier locations have vegetation consisting of many shrubs such as crowberry and blueberry. In the summer, the wetlands of the Hudson Plains attract millions of migratory birds, such as snow geese, Canada geese and king eider ducks. Mammals which can be found here include moose and black bear, but small mammals such as muskrats and weasels are more common.
The plants growing among Montana’s peaks and valleys range from tall evergreen trees to grasses. The mountainous areas are covered with forests. However, at each level, from the mountaintops to the valleys, there are different, distinct collections of plant life. The mountainsides are largely covered with towering spruce, pine, cedar, and Douglas fir trees (Av2
The Northern Spotted Owl can only live in old growth environment, it is considered an “indicator species”: The health of the Northern Spotted Owl population indicates the health of the old-growth forest ecosystem. An individual Northern Spotted Owl needs more than 3,000 acres of old growth to survive, because of its scarce food supply. The Northern Spotted Owl is found in the cool, moist woodlands on the Pacific Northwest. The habitat of the Northern Spotted Owl can be described as trees relatively large in diameter in the stand, multi-layered canopy, large tall live trees with cavities, broken tops, mistletoe, or platforms of branches capable of holding accumulated organic matter suitable for use as a nest, dead standing trees and fallen decayed trees to support abundant populations of prey species, especially northern flying squirrels and woodrats.
In conclusion, owls have shown they are excellent at adapting to any environment by the ability to fly silently to stalk prey. They use camouflaged and insulated feathers to hide and keep warm while hunting. Owl’s excellent binocular vision, and hearing helps to track prey from long distances. The only real risk of extinction of the burrowing owl is if people continue to kill off animals that dig holes for them. They have shown the ability to survive for a long time with the help of other animals digging holes for them. Owl’s will continue to evolve long after humans have
direction, the major problem for their decline would have to be remedied – loss. of the habitat of the sailor. This fact combined with the owls' short life expectancy and late age. breeding only exacerbates the problem. When loggers remove old growth owl loses habitat for its food, housing, as well as protection from predators.
The Cooper’s Hawk, breeds mostly in the United States, southern Canada, and northern Mexico. This species was named in 1828 by Charles Bonaparte for his friend and collogue William C. Cooper. They are migratory birds that focus highly on thermal air for direction. Female Cooper’s Hawk is one third larger than the males, and this species is a great example of dimorphism. They are among one of the most reverse sized dimorphism of any hawks in the world. They breed in forests and dense woods. They are also noticed to live in suburban and urban habitats. They consume prey of different sizes, including birds and mammals such as doves, robins, chipmunks, squirrels, and different rodents. In mid 1990s, the eastern population of the birds declined significantly. Some major causes of this decline in population include trapping, pesticide contamination, pollution, and shooting. Thereby, the specie is stamped as threatened or endangered species in some eastern states. Although their population was low, it is slowing recovering now in many areas. Over the years, this specie has been studied intensively by ornithologists and they have put in a collaborative effort to document the specie’s habitat and other characteristics.
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
Some of these landforms include the following: hummocks, or knolls, frost boils, and earth stripes. Another common area to the alpine tundra is a “bare rock covered ground” also known as fell fields, in which not only support but helps the growth of lichens. The many “microhabitats” given by these landforms provide a variety to the tundra’s landscape. As you already know, the amount of different plant species in the tundra is very small. Also, their growth level is low, “with most of the biomass concentrated in the roots”.
One way that the environment impacts the animals is that the animals such as bears adapt and store their energy in the winter. This is also known as hibernating. “Animals in the mountains have also adapted to save energy during the harsh winter months.” (Cassandra Maier, Adaptations of plants and animals to mountains) When animals hibernate, they are less active during the winter, and they just sleep for most of the day. Other animals such as the goat and deer do not hibernate during the winter,
The bald eagle (Haliaeetus leucocephalus) is a bird of prey and is most commonly found in North America. Its habitat is anywhere near large areas of water surrounded by many tall trees. They feed mainly on fish, which they grab from the water with their talons. Due to human impact, particularly from the use of guns, the bald eagle has faced extinction.
The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem
One huge impact of global warming is the change in animals’ habitats. When the earth’s temperature is increasing, it creates the change of weather conditions in a certain area, which causes some kinds of animals in this area to live with many difficulties, or sometimes those kinds of animals are forced to move to new region when they cannot handle the difficulties. The arctic fox is an example for this situation. According to the article “How Does Global Warming Affect Wildlife,” arctic foxes prefer to live in the cooler environment while their habitat is getting warmer and warmer due to global warming, so arctic foxes have to leave their own home to seek a more suitable area (National W...
The early Eskimos settled in the forest and tundra parts of northern and western Alaska. The Eskimos learned how to survive in this cod icy place that was frozen for most of the year. Some of the Eskimos lived in the southwestern part of Alaska The southwestern region is a little warmer and wetter.
