Explaining Succession Introduction Succession is the progression of plant and animal species in an area from smaller simpler organisms to larger more complex organisms, eventually leading to a climax community. The climax community is reached when the species found in the area remain constant over time with few or no species being wiped out or starting to grow- there is an equal balance between births and deaths and gross primary productivity is the same as total respiration. The climax community exists as long as biotic and abiotic factors allow. Things which could devastate a climax community include forest fires and drastic changes in climate, or biotic factors like Dutch elm disease, a fungus transmitted by European and American bark beetles which killed millions of elm trees in the 1980's. The climax community arises in stages called seral stages. There are two types of succession, primary and secondary. Primary succession A primary succession is one that takes place in an area or piece of land which was not previously populated by other organisms. Examples of places where primary successions can take place include newly bared rocks, sand dunes, river deltas where fertile silt is deposited, hardened lava from a volcanic eruption or in a freshwater lake. A xerosere is the name given to a succession which begins on dry rock and the plants which grow there are called xerophytes. A hydrosere is a succession beginning in water with plants called hydrophytes. The first plants to become established on a bare area of land are called pioneer populations. The plants which occur in the pioneer populations vary accord... ... middle of paper ... ... forest which was cut down to grow crops or graze animals on. After the land is abandoned, small weeds appear which give way to larger plants, bushes and shrubs, which are then superseded by larger trees and deciduous woodland. This whole succession can take place in just over a hundred years, whilst the succession to woodland in a freshwater lake can take up to ten thousand years. Conclusion: All landscapes have resulted from a succession of some sort and complex organisms would not be able to survive without the land first being made habitable by smaller plants with adaptations to survive in hostile conditions. Animal succession relies directly on plant succession to take place, since without the smaller plants as a source of food and shelter, the smaller animals would not be able to become established.
“The Inheritance of My Father: A Story for Listening” comments on the issues of family ties, identity and belonging in relation to hybridization. Roemer’s purpose involves the highlighting of the relationship between finding one’s identity and finding one’s voice. He achieves this by allowing the readers to embark on a journey of self-discovery with the child narrator Bonkoro, who changes from a docile, almost voiceless “child” before the summer vacation to a renewed, confident and articulate “adult” at the end of her vacation. This short story is a unified and coherent production since several aspects of Roemer’s craft testify to the intimate interrelation of finding one’s identity and one’s voice. Roemer emphasizes the theme of self-discovery
Secondary succession occurred while Simba was trying to take back the throne. In the progress of doing so, a fire started. The fire caused the vegetation to burn, which would lead to secondary succession. This will change the community because the vegetation would have to regrow over a period of time, and while it is in the progress of growing back, the lion and hyena population will have to travel to get food. This fire is similar to a real forest fire because in both communities, the vegetation would grow back over a period of time, and the remaining animals that survived would have to travel to find
What creditor protection was provided to Mr. Dutton’s assets in the course of implementing his estate plan?
The achievers, the gamblers and visionaries, and the undefined, this is how Jeffery Kluger describes the oldest, youngest, and middle child in his article “The Power of Birth Order” (409). The birth order is a phenomenon, studied by many scientists, that has been impacting the way siblings think and act for years. The birth order classifies the oldest child, who is the achiever; the middle child, who is a hybrid of the oldest and youngest; and last but not least, the youngest child, who is the adventurer of the family. The fact that the birth order affects the personalities of siblings is becoming more and more evident and the classifications of the firstborn, middle child, and youngest child have been proved to be very accurate.
Settlers who first arrived at the Great Plains found the grasslands keeping the grain like soil intact. In result many settled down in the area and began building ranches and farms. At firs the there was mostly cattle ranching and some farming. However, a series of droughts and overgrazing of the grasslands let to the growth of land cultivation. Also recurrence of wet weather led to the belief that “previously” dry land is suitable...
The patterns of birth order have been seen for centuries, although it was not studied exclusively until around the 1980s. There are many factors that play into a persons personality, such as their genetics, the way they are raised, and their environment. Birth order looks at a persons place in their family—if they are the oldest, middle, or youngest child—and provides commonalities between them and others in the same location in other families. While there are many variations, the general traits do apply. Research shows that the first born is typically a leader in the family and in other areas of life. The youngest child is usually light hearted and social. The one that is hardest to put a type to is the middle child. He or she will frequently try to blaze their own path, straying from the one that their older sibling made. I believe that birth order plays a part in a person’s personality, but that the way they were raised is also a very important variable. A child’s birth order, along with the way they were raised, is a major factor in the way they interact within their family and other groups.
Tim Kastelle’s article Hierarchy is Overrated is focused on the relatively new and growing flat organizational structure. He begins with an example of the Second Chance Programme, “a group that raises money to help reduce homelessness among women.” Second Chance Programme is a non-profit organization run by a committee of ten people. When the non-profit was first founded a management consultant predicted its failure because of its decentralized structure, assuming a hierarchical structure is important for success. Ultimately the organization ended up being successful, despite this prediction.
There is clear difference in seed dispersion and tree density in woodlot and Oldfield, the key difference relies on the type of habitat it nurtures and the kind of growth it allows. Some of the observed differences in Oldfield, that it’s an open place with constant sun which causes higher temperature, there are no trees but more flowers, the ground is not wet, there was not many animals inhabiting it, and it is less diverse compared to woodlot. According to this study, Animal species abundance, are thought to be correlated with size of natural environment and resource availability3. Furthermore, it was confirmed that species distributions are influenced by elements like soils and habitat factors3. On the other hand, woodlot had more shade which led to cooler temperature but higher humidity, it was more damp and wet. Furthermore, it is established by this research, that the difference between the average (daily) temperature of two habitats; a denser habitat and an open-field one was generally found to be highly significant value (p < 0.0001), and the average of the Relative Humidity was found higher in the forest /woodland habitat than an open-field1
The Demographic Transition Model (DTM) shows how the population of a country changes over time. This is explained through changes in both birth and death rates. These changes can be easily seen and mapped between five different stages of population growth, which can be seen in both More Developed Countries (MDC, and Less Developed Countries (LDC) in several ways.
On the second level, the introduced species starts to reproduce faster than other native species around it. It also out-competes native species for resources
To begin with, one result from the domestication of plants is that the land changed considerably and consequently it was no longer substantial enough for complete sustenance of those who depended on hunting and gathering. Equally important, it was transformed into particular territories, collectively or individually. Another dramatic effect
By state law, guardianship is a relationship between the guardian and court that gives one person or entity the duty and power to make personal and/or property decisions. Guardianships are designed to protect the interest of incapacitated adults and elders. Pam Wright, licensed attorney in Tennessee and elder law specialists said, " I always tell people to think about it earlier if possible because if you can make some of these decisions and think about this while you are able to make your own decisions, you can decide who can handle your business ahead of time."
Prior to the Age of Exploration, hardwood trees blanketed all of Europe to form a forest giOB47;comparable in size to the Amazon Basin” (David Morse). Forest density was intense, such that “scattered clearings must have appeared like islets in an ocean of green” (Morse).
Adler believed “it is the feeling of inferiority, inadequacy, insecurity, which determines the goal of an individual’s existence.” His theory applies to every individual because in childhood everyone has felt sense of inferiority in them. The only difference is that some are able to overcome it some do not. To Adler, healthy individual drive toward superiority as a way to compensate for the inferiorities felt during childhood. However, superiority according to Adler does not specify to be superior to others but signifies moving from a perceived lower position to perceived higher position. Not only this, Adler also took into account individual life style and birth order. His approach to give emphasis to the relationship between siblings and psychological birth position is exclusive. It is obvious for people to think why children from the same family are different even though they come from same environment. Even though sharing some aspects of the family pattern, each child becomes different due to birth order. If we look in our own family, we can easily understand what Adler mean by this behavioral distinction by birth order. I am eldest child in my family, thus more pampered and looked upon until my brother was born. When my parents were more into taking care of my brother, I automatically became their helping hand to help raise my brother. Now, he is totally dependent on me for every decision he makes and looks upon me as his mentor or role-model. As we pass from one stage to the next, often with some difficult periods of transition, we learn and mature in the process. Throughout the life span, the importance of roles may change, varying with the stages. Every individual pass through these stages of life thus should prepare them...
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.
