Climate Change Affect Plants Essay Example for Free

Climate Change Affect Plants Essay Historical climate change has had a profound effect on current biogeography, so we can expect our ongoing and rapid climate change, to have as great an effect. Climate change has important implications for nearly every aspect of life on Earth, and effects are already being felt. * Temperatureeffects–average, minimum or maximum can be important determinants of plant distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem is susceptible to frost. Conversely, boundaries between vegetation types (e. g. Arctic treeline) are generally determined by summer warmth * Rainfall is also an important determinant: for example it affects the balance of grasses to woody vegetation * Other factors such as soil type or herbivory may also be affected by climate change. Effects on Plant Diversity * Species ‘left behind’ as they are unable to change distribution fast enough. Species with long life cycles and/or slow dispersal are particularly vulnerable. Some isolated or disjunct species are particularly vulnerable, as they may have nowhere to go. These include Arctic and alpine species, and Island endemics Coastal species which will be squeezed between human settlements and rising sea levels. * Plant genetic composition may change in response to the selection pressure of climate change. * Some plant communities or species associations may be lost as species move and adapt at different rates. Increased invasions by alien species may occur, as conditions become more suitable for exotic species whilst native species become less well suited to their environment (for example, Bromus is more invasive in wet years (Smith et al, 2000)). This is especially true given human interventions which have deliberately and accidentally facilitated the spread of species across the globe. * Many plant communities act as sinks (store carbon), which helps to offset carbon emissions. However, over the next 70 years, the effects of climate change on plants mean many terrestrial sinks may become sources.

From Moniza Alvis poetry, how do we learn about the challenges of Essa

From Moniza Alvi's poetry, how do we learn about the challenges of living between two cultures? Moniza Alvi writes many poems based on the difficulties she faces whilst living between two cultures and I am going to explore these difficulties through the following poems: - "The Sari", "Throwing out my Fathers Dictionary", "an Unknown Girl" and "Presents from my Aunts in Pakistan." Firstly, I am going to discuss her poem "The Sari" which is a metaphorical poem telling us what happened to her in early life. The poem begins, "Inside my mother I peered through a glass porthole", which creates an image of a baby in the womb. It then continues to say, "the world beyond was hot and brown", which suggests that she was born in Pakistan. The second stanza represents her Pakistani life consisting of a father, servants and animals; "They were all looking in on me - Father, Grandmother, the cook's boy, the sweeper-girl, the bullock." This shows us the differences between the Pakistani and English culture and also what her life would have been like if she had stayed in Pakistan. The phrase "the bullock with the sharp shoulderblades" uses a repetition of soft consonants suggests a feeling of calmness at being somewhere she knows she belongs. The third stanza links her Pakistani and English roots, "My English grandmother took a telescope and gazed across continents", giving the notion that her Grandmother wishes for he upbringing to be in England. The use of the word "gazed" in particular gives an impression of great eagerness. The third stanza begins with her journey from Pakistan to England; "All the people unravelled a sari. It stretched from Lahore to Hyderabad." This suggests that the unravelling sari is showin... ...ttempts to recreate herself in their culture. As you can see, Pakistani beliefs are very different to those held by the English. Moniza Alvi's poetry is deeply influenced by her cultural influences. This is obvious because the majority of her poetry is based on the difficulties of living between two cultures. Her poetry is also influenced by fashions in writing. Her style is very modern and contrasting to pre-20th century poets, and this enhances younger reader's appreciation of the text. In conclusion, Moniza Alvi was privileged to have lived between two cultures because it meant that she was welcomed into two communities and had the opportunity to experience different ways of life. However, all good things come at a price and for this she suffered the issues of not knowing where she fit in, which values she held and having high family expectations.

Learning and Memory Essay

If one were to explain what it is to learn something new, they would certainly mention memory somewhere in their explanation. As well as if someone was to explain memory, they certainly would have learning mentioned in their explanation. This is because learning and memory go hand in hand. When one learns, they store what they learned in their memory whether it is short term or long term. It would go without saying that memory and learning has to do with the brain, hence the importance of keeping one’s brain functioning properly by insuring proper stimulation and continuously learning new things. Now, the ability to learn and to memorize what is learned stems from different areas of the brain. The brain is a part of an individual’s neuroanatomy. Neuroanatomy refers to the structure of the nervous system. The nervous system is made up of different parts. Those parts are broken up by having the main one being the nervous system, and then it is divided by the central nervous system brain and spinal cord on one end. The other ends are much more complex and, consist of the peripheral nervous system which then branches off to other ones. These each control different parts of the nervous system and give the ability for people to sleep, eat or learn. The part of our nervous system that pertains to learning is the brain. The part in the brain that helps with learning is called the hippocampus. The hippocampus is in the limbic system. It is the part of the brain where the learning that people do in day to day life takes place. Learning is a neurobiological that is important to humans and being able to be conscious. The communication that happens between singular neuroanatomical structures and their abilities to repeat neurophysiologic activities is combined as a network of neural activity. These things occur in the cortex and create different types of learning for people. The movement that is ongoing changes in the synaptic area of the nerves. These active activities make the synaptic connectors stronger with the result of the continuous activity and then this creates memories that help an individual learn and remember what they have learned. It has been taught that learning is not singled out to one certain area of the brain itself. The cerebral cortex is where all the learning is. When a person is learning to read, walk, or talk it occurs here. One of the many different neural processes involved in learning is the synaptic inputs that occur in the brain. When a synaptic input in a certain neuron is combined with two different synapse then; it creates a long term depression or a long term printed memory, this is something that occurs and has been known to create learning involved with motor skills. Learning is mainly either a process that one learns through the brain with the use of classical conditioning and also instrumental conditioning. Our brains respond to the many different things that are in a human’s surroundings. In the process of a human’s learning new things is by the development of a neuron and its effectiveness to make new synaptic connections or reinforcing the strengths of the neurons that are already in place. The relationship between learning and memory has been a subject of much debate among psychologists, teachers, and society in general for many years now. It is what we learn and how we learn it that is responsible for how we live in the world and how we deal with the world around us. Learning has been a fundamental part of our survival ever since Cro-Magnon man. He/she had to learn how to make spears, sharp points, even mastering the bow and arrow was important to the survival and the spread of the human species. Why, though, if humanity has so much â€Å"experience† in learning, then why do we forget things? The brain is the organ that is responsible for what we call the mind. It is the basis for thinking, feeling, wanting, perceiving, learning and memory, curiosity, and behavior. Memory is a fundamental mental process, and without memory we are capable of nothing but simple reflexes and stereotyped behaviors (Okano, 2000). Both the brain and memory are responsible for our learning. The brain assists us in figuring out a solution to the problem and to solve it. Our memory is responsible for storing that information within our brains in case we ever need it for a later date, or if we ever need to apply it to another problem which is similar. During this learning process, our brain is communicating with that section of our mind that is responsible for memorizing methods, actions, and procedures for finding a solution to a given problem. Since our memory is only a mental process and not a â€Å"supercomputer† like the brain, it stands to reason that our memories need to recall different types of information using dissimilar methods. We define memory as a behavioral change caused by an experience, and define learning as a process for acquiring memory. According to these definitions, there are different kinds of memory. Some memories, such as those concerning events and facts, are available to our consciousness; this type of memory is called â€Å"declarative memory. † However, another type of memory, called â€Å"procedural memory,† is not available to consciousness. This is the memory that is needed, for example, to use a previously learned skill (Okano, 2000). When someone is learning something, they assume that they are acquiring the knowledge to write a paper or to build a chair. Actually, all a person is really doing is creating memories for them to recall the information. While we are in the process of creating these memories, our brains are at work in determining the best ways to store them in our memories. This might be learning a piece of music by only playing the 3rd or 4th notes, or by building a chair by starting with top first instead of the bottom. Each person’s brain is different from another person so each method of memorization would be different. This theory has been proven using animals that work together. For instance, one taxonomic group of birds, the oscines or true songbirds, all learn to sing by imitation. To produce biologically functional songs, they need to hear examples of species songs during development, which they commit to memory. They subsequently perfect their song performance by ear and are capable of using both memorized material as well as songs of birds they can hear to produce an acceptable species song (Okano, 2000). Birds, and other animals, have shown that they use memory in order to learn a skill or to work together to achieve a common goal or result. The ability to apply the right knowledge effectively is an important skill and the cornerstone of our success, because we live in the Knowledge Age. People who have not used a computer in 10 years to find an article on the Internet definitely understand strength of knowledge and learning. Learning develops interesting people. Knowledge enables us to have different perspectives, fascinating conversation and a deeper understanding. It makes us well rounded better people; it allows us to make better, informed decisions; and assists us in becoming more successful in our lives and careers. Technology has made our lives become fast paced; the advancement of technology has boosted the pace of our lives, and requires us to learn something new each day just to stay current in the workplace. The day’s on-the-job training is something we can no longer rely on; companies can no longer be the basis to provide the necessary education. We must seek out more education just to keep up. It’s advantageous for everyone to make time for learning, seek out their own opportunities, use available resources wisely, and find new resources. Our children are a good example of how fast technology has increased the need for learning. They our learning how to use technology much earlier than we ever did, it seems like they are born with the ability to operate a computer. Brain stimulation can help with Parkinson’s disease, chronic pain, Major depression, and Tourette syndrome. Stimulating the brain helps to relieve symptoms of these conditions when medications are not working or have major side effects. The stimulation can help people with Parkinson’s disease to manage their symptoms of tremor, rigidity, bradykinesia and postural instability. Brain stimulation has produced impressive results with some patients with chronic pain, some patients are virtually pain free after treatment and even released from the hospital. Brain stimulation has been found to significantly decrease depression and increase in function. Although highly experimental, brain stimulation has had success. Patients experience reduction in tics and the disappearance of obsessive-compulsive behaviors. Lifelong learning and brain stimulation helps to manage and relive a symptom which increases life longevity and quality of life for the patients. Patients who continue to learn and stimulate their minds increase life longevity and quality of life because they are able to eliminate medications which can have very harmful side effects. These medications can actually shorten life and decrease quality of life because of the side effects. Taking medication out of the treatment of any kind will always increase life longevity and quality life. Most of all any time a patient is able to manage and relive symptoms, their life longevity and quality of life will have a great increase. As must as society tells us our physical up keep is so important for our health and life longevity, it would seem keep care of our brain is just as important as well. The brain is a muscle, and it is a part of our nervous system. It controls our breathing, eating, learning, memory, and so much more. Keeping care of our brains allows an individual to learn, remember things, and increase their life longevity as well. It would not seem that is keeping up on learning and remembering what we have learned will make us live longer, however this is how this muscle is exercised! It can also help control and care for one’s mental defects as well. It would seem, no matter what someone is wanting to believe, learning is never finished! REFERENCES Fernandez, A. (2011).

Wuthering Heights - 1100 Words

How does Emily BrontÃÆ' « make us sympathize with Heathcliff? Heathcliff is a ruthless character. No obstacle ever gets in his way when it comes to exacting revenge on several other characters in the novel, be it Hindley or Edgar Linton. He will kill or torture young and old to pay back those who have hurt him and deprived him of his love for Catherine. However, among all these atrocities, we still feel great sympathy for him. This is mainly due to the many techniques employed by BrontÃÆ' « and the effect of these in creating understanding and pity for Heathcliff. Perhaps the most significant factor that makes us sympathize with Heathcliff is his troubled and problematic character. Two particular incidents highlight this point very well.†¦show more content†¦The poetic nature of his narration is pitiful. His love for Cathy has taken him from being a revenge ridden, hatred filled character to one who talks poetically about love and loss for Cathy (even though this may only occur on one occasion). This extract almost completes the character of Heathcliff. We have seen Heathcliff through the eyes of Lockwood, Nelly, and now his own. However, more importantly, we sympathize with him because BrontÃÆ' « has somehow built a character that takes every emotion to new extremes. He can be so full of anger that we would go as far as à ¢Ã¢â€š ¬Ã‹Å"smashing Haretonà ¢Ã¢â€š ¬Ã¢â€ž ¢s skull into the stepsà ¢Ã¢â€š ¬Ã¢â€ž ¢ (chapter 9) just to avenge Hindley, to someone who talks poetically about his love and loss for Cathy. In Heathcliff, Bront ÃÆ' « has constructed a character that shows everything, and this is why the audience can not only sympathize for him, but also share many of his feelings. Overall, Heathcliff is an unfortunate character that we can sympathize with although he is a ruthless person. The fact that we have a first hand account of his troubled past and childhood influences the audienceà ¢Ã¢â€š ¬Ã¢â€ž ¢s emotions.
