Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
The characteristics of the tundra are as follows:
1. Extremely cold climate
2. Low biotic diversity
3. Simple vegetation structure
4. Limitation of drainage
5. Short season of growth and reproduction
6. Energy and nutrients in the form of dead organic material
7. Large population oscillations
Arctic tundra is located in the northern hemisphere, encircling the North Pole and extending south to the Coniferous forests of the Taiga. The arctic is known for its cold, desert-like conditions. The growing season ranges from 50 to 60 days. The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F), which enables this biome to sustain life. Rainfall may vary in different regions of the arctic. Yearly precipitation, including mel...
Due to the moderating effect, this ecozone has long, mild summers (18 to 22°C) and cool, short winters (-3 to -12°C), with around 720 to 1000mm of precipitation, and 180 to 260 growing days annually. The Westerlies can also alter the weather quickly in this ecozone.
The Taiga Biome is a large, naturally occurring community of flora and fauna occupying a major part of both Siberia and North America. It is usually found at high elevations at more temperate latitudes in the Northern Hemisphere. It is the largest terrestrial biome on earth, covering around 50 million acres of land (NP, UC Santa Barbara). It is known for its subarctic climate that ranges between -51 to -1 °C in the winter and -21 to 7 °C in the summer. The two main season found in the taiga are summer and winter as autumn and spring are usually very short and barely noticeable. Winter makes up around six months of the year, with only around 50-100 frost-free days during the summer. Summer is also the season during which the taiga receives the most precipitation in form of rain. The remainder is made up of snow and dew, which adds up to around 30-85cm of precipitation yearly (NP, S.L. Woodward).
Even the Antarctic area has a couple of its own arctic regions. The climate of the tundra is characterized by harsh winters. The average temperature in the tundra area is about –27 degrees. But what is even worse is the long night. At night the lowest temperature recorded was –67.36 degrees.
The Alaskan moose are located between 60 and 70 degrees latitude in Alaska and Western Yukon. They reside in boreal forests which is an area “dominated by coniferous forests, particularly spruce, interspersed with vast wetlands, mostly bogs and fens”. and mixed woodlands which consist of both coniferous and deciduous trees where there are many fallen trees and much debris. This region receives very harsh winters, the ground is covered with snow and temperatures fall as low as −60 °F or -51.1 °C and so by early spring food is very scarce. As the warmer temperatures of late spring and summer arrive food becomes plentiful as shoots, grass and leaves begin to grow. Summer temperatures can reach as high as 90 °F or 34 °C, while precipitation in this region can range from 10 inches to 100 inches of rain per year. This mostly comes in the form of snow.
Generally though since climate more or less corresponds vegetation zones, the Tundra is located in Arctic climate areas. Temperature The Tundra suffers from a very harsh climate. Because of this fact most of the area remains barren, save for a few shrubs and lichens. Winters last from 8-10. months and the summers are cool and short.
The ice caps are the most extreme climates on earth. They are located at the north and south poles. These poles are
Dementia is a common syndrome found among elderly over the globe. Talking about dementia, the first word emerge from mind is “loss”. Learning about the disease manifestation, it is known that dementia does bring a huge impact to the affected senior so as the caregiver. Many of us used to focus on the losses of dementia client which indeed causing a labeling effect. Remembered in the first lesson, a question “As a case manager, what will you do to help the client with dementia and the family?” was asked. I realized my answer is “Refer the client to suitable care unit”. It seems that my original thought deprived the elderly as I failed to think of other better solution like assisting them to age in the community. Although dementia leads to certain kinds of loss to people with dementia, their needs and strengths should not be neglected. Institutionalization thus may not the best solution. To serve the elderly, I need to modify my thought by adopting a strength-based approach. Practice should not mutually focus on the losses, but to explore more on the possibilities. Boosting the quality of life is also an important issue, empowering the client by bear in mind that “we are not only work for the service users, but work with them”.
Ice is one of the major abiotic factor in the arctic, without the ice, many organism such as polar bears would be left without a place to live and even with seals, it would be unsafe for them because without ice, there will be no places to hide from predators. Other factors are permafrost, strong winds, poor soil, long winters and short summer.
It’s an icy cold region, with barely any vegetation. There are harsh windstorms, which makes it incredibly hard to hunt. They have a lot of tools that make living in the Arctic easier, but I still find it the hardest, and worst area of Canada to live in.
Delirium, Depression, and Dementia are some of the most common psychological diagnoses in the elderly today. The three D’s are difficult to differentiate between in older adults because they overlap with each other and can all exist in the same patient at once. Delirium, Dementia, and Depression all affect the elderly’s quality of life and often increase the risks for one another (Downing, Caprio & Lyness, 2013). For the purpose of this paper I will be focusing primarily on the diagnosis of Dementia, the prevention, and nursing measures associated with it, but first I would like to differentiate between Delirium and Depression because Dementia is often associated with the two in the older adult population.
Introduction This assignment critically discusses dementia, a widespread disability among older adults today. It provides an introduction to dementia and analyses its prevalence in society. The various forms of dementia are elaborated with descriptions of dysfunctions and symptoms. Nursing Assessment and Interventions are provided in the further sections which discuss actions nurses should take while evaluating patients and treating them.
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 tundra is a biome that is located in the Northern Hemisphere of the world. It circles the North Pole and reaches down to the taiga. The tundra has a very cold and harsh climate, especially in the winters. The average winter temperatures is about -30°F and average summer temperatures is roughly 37-54°F. The yearly amount of precipitation, which includes melting snow, averages to about 6 to 10 inches. With these conditions it makes for a short growing season of about 50-60 days. In some parts it can be up to 180 days. This is only found in the more southern part of the tundra. Another aspect of the tundra includes the vegetation that is found there and the adaptations that have been made.
There has been many research endeavors into the topic of the aging memory specifically short-term memory and recall performance with age. However, there seems to be a lack of research regarding the difference found between young and middle adulthood.
Historically, memory has been a recurring topic in cognition research. Through the years, many scientific findings have helped us to understand how memory works. Since, older adults are the subgroup most affected by frequent memory deficiencies, they would be highly benefited with the advance of the cognitive
