The Effect of Species diversity on Ecosystem Resilience Hunter Greer Mr. PattersonSBI 3U Block I September 14, 2017 Abstract: The purpose of this lab was to see if the amount of plant species affects the resistance of an ecosystem. The way I did this was I went to page 39 in the textbook and I looked at the chart of information. It had the resilience a plant community had verses a drought depending on how many species where in it. In the end I found out that the more species there are in an ecosystem the more resilience it has to drought. Introduction: In an ecosystem from 1986 to 1988 scientists determined the resilience of the ecosystem through its entire cycle, lowest level to peak level …show more content…
Resilience is the ability of an ecosystem to maintain a balance despite disturbances like droughts, disease, etc. How is resilience related to species diversity within an ecosystem? Resilience is related to species diversity within an ecosystem. They are relate because in scientific study's it shows that areas that have more species diversity have higher resistance to invasive species and decreased incident of disease. 3. Why is it important to maintain biodiversity in ecosystems? It is important to maintain biodiversity in an ecosystem because it increases resistance to disease, invasive species, etc. As well It will keep the ecosystem more stable and make it healthy. Purpose: The purpose of this lab was to see if the amount of plant species in an ecosystem affects it resilience to droughts, diseases, …show more content…
Go to https://nces.ed.gov/nceskids/createagraph/ Then use the information in the text book to create a bar graph on the website above. Data analysis and Interpret: As shown from the data in the graph the more plant species in the ecosystem the more resilience it had. When the ecosystem had only two plant species in a drought the resistant was –1.1. When the ecosystem had 8 plant species it had a resistant rate of –0.65 this was a .55 increase in resilience to the drought. Then when the ecosystem had 24 plant species it's resistance to the drought was -0.38. Which is a 0.27 increase in resistance to the drought from -0.65. I predict that the ecosystems with the most plant species will go back to normal conditions after the drought faster than those with less plant species. I predict this because they had a higher resilience rate so they were not as affected or damaged as the ecosystems with less plant species.
Resilience gives people living in poor conditions a way to change the way they perceive situations by creative a view of positivity. Relationships between poverty and the environment in rural destitute neighborhoods are not

Resilience is having the motive to go through hard times and ‘bounce back’ from them and learnt how to deal with certain situations. To be resilient you must have a positive point of view on life. Anh’s book ‘The happiest refugee’ He was born into a 1970’s Vietnam, He and his family were forced to leave their country due to seeking safety and freedom from war. Anh uses resilience through his comedic, selfless actions. Resilience has allowed Anh to improve the quality of his life, and the lives of those around him.
Resilience and hardiness has long been a topic of research and discussion within different paradigms and fields of study, for example, in military psychology, psychiatry, health statistics and measurement, medical anthropology, education, medicine and organizational settings. Resilience means the skills, abilities, acquaintance, and insight that accumulate over time as people struggle to conquer adversity and meet challenges. It is an ongoing and developing fund of energy and skill that can be used in current struggles (Saleebey, 1996; Liebenberg, 2005).Most commonly, the term resilience has come to mean an individual's ability to overcome adversity and continue his or her normal development.
Resilience is not an attribute or personality characteristic of an individual but a dynamic process wherein people show positive adaptation despite experiences of major adversity or trauma. (LUTHAR & CICCHETTI, 2000) Resilience is a two-dimensional construct regarding adversity exposure and the proper adjustment outcomes of that adversity. (LUTHAR & CICCHETTI, 2000) The two-dimensional construct means implies two judgments about the significance of adversity and a positive adaptation to adversity. (Masten & Obradovic, 2006).
Purpose: The purpose of this lab is to investigate the various components of different ecosystems in a smaller representation and study the conditions required for the ecosystem’s sustainability as well as the connections between
With global warming on the increase and species habitats on the decrease, the chances for various ecosystems to adapt naturally are diminishing. Many studies have pointed out that the rates of extinction of animal and plant species and the temperature changes around the world since the industrial revolution have been significantly different to normal expectations.
The Oxford dictionary defines the word resilience as “the capacity to recover quickly from difficulties” (Oxford Dictionaries | English, 2017). In simpler words the term resilience is the ability to bounce back from tough situations. This straight forward definition of resilience is only one of many ways in which people define resilience. Psychology Today simply states that people who are resilient do not dwell on negative things that happen to them or in their lives, and rather get on with things, “Resilience
Resilience is important because it is the human capacity to face, overcome and be strengthened by or even transformed by
Native plants in any given area have adapted to all the other organisms in a given area and genetically diverse ecosystems are generally maintained.
Climate change has been happening for many years and it continues to do so. It is a significant change in regards to the distribution of weather patterns over a given time frame such as decades or millennia. In recent times, the climate change is called “global warming” and it has been linked to certain human activities (NRC 2010). This shows that climate change is not limited to biotic factors. In a general sense, these changes have the potential to impact populations and ecosystems due to alterations in the water cycle. Climate change impacts includes too little water in some regions while too much water in other regions. Changes in precipitation patterns can influence plant physiology and thereby affect the rates of photosynthesis. Such patterns include drought in which warmer temperatures increase evaporative stress on a plant and increased rain or frequency of storms can influence water uptake by plants. Under both conditions, there is a change in photosynthetic rates. Photosynthesis allows the plant to accumulate carbon, grow and produce biomass (Niu et al. 2008). Therefore, a change in photosynthetic rates can be either beneficial or harmful to a plant. The effects of altered precipitation patterns on photosynthetic rates is significant to the scientific field because it gives insight on the shifts in plant community composition and how it affects the water availability for human and ecosystem uses (Kray et al. 2012). In addition, understanding the connection between water relations and photosynthesis with respect to changes in precipitation patterns could help with management decisions of ecosystems, where climate change indicates alterations in species composition, in water availability for wildlife and in fire regimes (L...
Resiliency is an important factor to posses in a constantly changing world. Resiliency in the family, arguably the closest social circle an individual may have, is extremely important for a healthy family. Family resiliency is the ability to deal with a stressful family event and be able to cope as well as bounce back from it. It is important for a family to be able to adapt to the stressor and overcome it. After learning about family resiliency and thinking back to previous family experiences; such as my mom losing her ability to hear, I realize that my family in fact posses a great deal of it. After learning about family resiliency in class, I now have greater insights about how resilient my family has been through negative experiences.
According to the American Psychological Association website, there are 10 different ways to build resilience. Those 10 ways are Make connections, Avoid seeing crises as insurmountable problems, Accept that change is a part of living, Move toward your goals, Take decisive actions, Look for opportunities for self-discovery, Nurture a positive view of yourself, Keep things in perspective, Maintain a hopeful outlook, Take care of yourself, and Additional ways of strengthening resilience may be helpful (apa.org). In my perspective, three out of the 10 different ways to build resilience are more important: Make connections, avoid seeing crises as insurmountable problems, and accept that change is part of living.

Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
