Volcanic Activity Exploring Succession and Ecosystem Change Lab Assignment
For this lab, you need:Google EarthA browser with Adobe Flash PlayerThe ability to access videos onlineAn Introduction to Ecological SuccessionEcosystems are always changing. Ecologists and geographers are interested in this change. Is the change beneficial or harmful? To which species? Can we predict what an ecosystem will look like in the future? Succession is how ecosystems form and change over time. Succession comes in two types:Primary succession: where there is no ecosystem and no soil, so life is starting from “scratch” in an area.Secondary succession: where an ecosystem has been disturbed, from something as small as a falling tree, to something as big as a forest fire, but the soil remains intact.Please watch this video that’s just over 10 minutes about ecological succession.CrashCourse Ecology #6: Ecological SuccessionEcological Succession: Change is Good - Crash Course Ecology #6 (链接到外部网站。)链接到外部网站。Primary Succession: Two Explosive IslandsVolcanic activity is one of the most common ways to find examples of primary succession. New land has formed, but there isn’t any soil yet. In 2017, a new island formed in Tonga between two existing islands.Please watch this 5 minute video about the birth of a new island:The Birth of a New Island (链接到外部网站。)链接到外部网站。From 1963-1967, another new island formed in a similar way off the southern coast of Iceland. While we may speculate about what may happen to Hunga Tonga Hunga Ha’apai, we can see what has happened to Surtsey over 50 years later. Go to this website to read about Surtsey, and the first life that took hold there:https://whc.unesco.org/en/list/1267 (链接到外部网站。)链接到外部网站。Use Google Earth to look at both islands. You can find them using these coordinates:Surtsey: 63.30N, 20.20WHunga Tonga – Huya Ha’apai: 20.54S, 175.39WPlease answer the following questions.Use the coordinates provided and the map in your atlas to find the climate type for each of these islands using the Koppen Climate Classification System. List and briefly describe the climate type for both islands.Based on the climate type, what may be some different limiting factors for primary succession for the two different places?Hunga Tonga Huya Ha’apai formed between two existing islands joining them, while Surtsey island formed in isolation. How might this affect the succession of these two places?Surtsey has existed now for 50 years, and has some life on it. According to the materials provided, what was some of the first life to come to Surtsey, and how did it get there?You have been given funding to study primary succession at these two sites. Come up with a research question you would like to answer, and find at least one method you could use to try to answer your question. Please cite any sources you use.Secondary Succession: ClearcuttingSecondary succession looks a how an ecosystems forms after a previous ecosystem suffered some sort of disturbance. This can be something natural, like a fire, or cause by humans, like the example we will look at: clearcutting. Soils exist, so don’t need to be formed from scratch, but there is no guarantee that the ecosystem that replaces the old on will be of the same type that was disturbed.Clearcutting is a logging practice where a whole area of trees is cut at the same time, and often replanted with a monoculture of new trees. This is a very efficient, but highly controversial logging practice, so let’s take a look at some of the impacts and controversy around this practice.A very powerful tool used to study forest health is satellite imagery and remote sensing. One very cool thing about these sensors is that they can see types of light human eyes cannot. Near Infrared light is not visible to human eyes, but plants give off a ton of it when they are making food with photosynthesis. You can read more here:Reflected Near-Infrared Waves, NASA: https://science.nasa.gov/ems/08_nearinfraredwavesThe two images below are of forest clearcutting in Washington State using reflected near-infrared light. Areas of more near-infrared light are in green, and areas with less are in red. Green areas have the most healthy vegetation, and red areas the least. You can get a good idea about clearcutting and regrowth in an area by comparing these images:Source: Logging and Regrowth in Washington State, NASA Earth Observatory. July 5, 2011, viewed March 4, 2019. https://earthobservatory.nasa.gov/images/51257/log...You can see the full images below.1984 Washigton Clearcutting.jpg2010 Washington Clearcutting.jpg6. Describe how the forest has changed between 1984 and 2010. Is there more or less mature forest in the area? How would describe the regrowth area compared to the mature unlogged forest?Next, open Google Earth, and go to Mt. Rainier, Washington. You can see Mt Rainier in the bottom left corner of the full sized images. Zoom out in Google Earth until you are in the same extent at the satellite photos. The picture on Google Earth is different, because it shows the area in visible light, instead of near IR light like the previous images. Areas here with healthier forests are darker green, and the more brown, the less vegetation.7. Describe what you see in the Google Earth image forest cover compared to the images from 1984 and 2010. How have things changed? What looks the same? Make sure to talk about both regrowth areas and unlogged areas.Pros and consPlease explore these two websites about clearcutting. The first is from a logging advocacy group, and is very pro-clearcutting. The second is from a non-profit that is trying to end the practice.Oregon Forest Resources Institute: https://oregonforests.org/clearcutting (链接到外部网站。)链接到外部网站。Stop Clearcutting California: https://www.stopclearcuttingca.org/about-clearcutting/what-is-clearcutting/ (链接到外部网站。)链接到外部网站。 (make sure to look at the different sections, you can see the table of contents to the right. You must look at the first page, and “What’s wrong with it?”.)Please answer the following questions:8. After looking through the material, briefly list some pros and cons to clearcutting.9. You have the means to try and settle part of the argument over clearcutting. Select one of the concerns people have about clearcutting, and design a way to test if the concern is accurate or not. Please do some research of real methods scientists use to collect this kind of data, and cite your sources.Invasive Species: Zebra MusselsOne of the concerns about man made disturbance is that it provides opportunities for invasive species to take over an ecosystem. An invasive species is a non-native lifeform that moves into an area and causes damage to the area’s diversity and overall health. Invasive species can be a very serious problem. We will look at one of these species that has cause both economic and ecological harm in the US, the Zebra Mussel. Please watch this short video about zebra mussels and their impact on lakes in the US:"Silent Invaders" Zebra Mussels 2013 (链接到外部网站。)链接到外部网站。Use the graph below to answer the following questions:Densities of zebra mussels and unionid mussels are given in number per square meter, averaged over the freshwater tidal Hudson (RKM 99-248); data collected in August for zebra mussels and July for unionids. Scientists began collected unionid data in 1991. One meter squared equals ten square feet.Source of both graphs: Michelle Smith, Zebra Mussel Graphing Exercise, BIO 124 Lab, Windward Community College. Accessed 3/4/2019, https://windward.hawaii.edu/facstaff/miliefsky-m/B...10. When were the zebra mussels introduced to the Hudson river?11. Record the density of zebra mussels and unionid mussels for the following years: 1992, 1997, 2004. Please note: The density for zebra mussels is labeled on the left, and the unionids is on the right side of the graph.12. How did the native unionid mussel density change over this time period?13. How did the zebra mussel density change over this time period?Effect on Food SourcesTo understand the effect the zebra mussels may have had on the food supply, we first need to look at predator and prey relationships. Please go to the following website to explore how populations of predators and prey affect each other: http://www.phschool.com/atschool/phbio/active_art/predator_prey_simulation/index.html (链接到外部网站。)链接到外部网站。Please note: You will need adobe flash player to do this activity.The graph below shows the relationship between zebra mussel populations and their food supply, phytoplankton. Use what you learned about predatory/prey relationships and the graph below to answer the following questions.14. What are the phytoplankton population density for 1992, 1997, and 2004?15. Compare the relationship between phytoplankton density and zebra mussels. What patterns do you see?16. Give an overview of how you think zebra mussels have affected both native mussels and phytoplankton on the Hudson river based on this data. Please support your discussion with data and evidence.

Capella University Reproduction and Genetics Lab Report
For this assignment, you will be participating in a lab activity on genetics by analyzing the pedigree chart and karyotype for two patients.Reproduction and GeneticsThe reproductive systems of males and females are different but have the common goal of continuation of human species. We will look closely at the reproductive systems in males and females and inheritance of genes. Furthermore, we will explore genetic diseases in families and the concept of gene therapy for providing hope for genetically inherited disorders. Genetics can play a role in the traits that we inherit, but the environment around us can also impact our traits. We are born with a genetic code that is a culmination of genes from our parents and generations before us. Genetic diseases in families often are "hidden" if they are a recessive trait, such as cystic fibrosis or sickle-cell anemia. However, with the advances in science, gene therapy provides new hope for genetically inherited disorders like sickle-cell anemia.SHOW LESSHave you ever wanted to know more about where exactly you came from? It has never been easier to find out thanks to the explosion of at-home DNA testing kits. Millions of people have tried them, resulting in a great surge in popularity. Many new companies offer genetic testing, also known as DNA testing, which allows an individual to receive a genetic diagnosis of their vulnerabilities to inherited diseases. In general, this helps determine an individual's ancestry or biological relationships between people.

Such fears may dissuade patients from taking genomics-based clinical tests or volunteering to participate in the research necessary for the development of new tests, therapies, and cures. To address this, in 2008 the Genetic Information Nondiscrimination Act (GINA) was passed into law, prohibiting discrimination by employers and health insurers" (National Human Genome Research Institute, 2017).Find more about the NIH's work as you read the Genetic Information Nondiscrimination Act of 2008 that prohibits insurance companies and employers from genetic discrimination:Genetic Discrimination.ReferenceNational Institute of Health: National Human Genome Research Institute.

A karyotype is a picture of stained chromosomes arranged to show chromosome pairs. Abnormalities in chromosome number or size can be easily identified in a karyotype. Pedigree charts give a symbolic representation of phenotypic (observable) traits through a family. Using a pedigree, researchers can trace the pathway of a disease through families:Genetics Lab.ConsiderIf gene therapy was available to fix a gene before birth, do you think this might cross the lines of “unethical” research?InstructionsFor this assessment, you will complete a series of responses within the lab, complete an assessment at the end of the lab, and write a brief summary of your conclusion about the lab.To complete this assessment:Fill out the items requested in the lab.Complete the assessment at the end of the lab.Save a pdf of your responses and download it to your computer. You will have an option to download a pdf within the lab.Write a one-paragraph summary detailing new knowledge acquired in the lab.Attach both documents when submitting the assessment.Make sure that you read the Homework: Genetics Lab Scoring Guide prior to submitting your assessments to ensure you have met all of the expectations for this assessment.It is recommended that you review the scoring guide prior to completing the la as most work will be completed within the lab.Assessment Requirements Your summary should meet the following requirements:Length: Submit one double-spaced page.Written communication: Ensure written communication is free of errors that detract from the overall message.Standard formatting: Include one-inch margins, appropriate headers, and a title page.Font and font size: Use Times New Roman, 12-point font.Note: If you use assistive technology or any alternative communication methods to participate in this activity, please contact DisabilityServices@Capella.edu with any access-related questions or to request accommodations.

John Wiley and Sons.Chapter 21, "Inheritance, Genetics, and Molecular Biology." In this chapter, you will learn more about gene expression and inheritance. What are main differences between males and females? Why do I look like my mom and grandma, but not my dad?In addition, consider the work of the National Institutes of Health's (NIH) National Genome Research Institute to prevent genetic discrimination: "Many Americans fear that participating in research or undergoing genetic testing will lead to being discriminated against based on their genetics. Such fears may dissuade patients from taking genomics-based clinical tests or volunteering to participate in the research necessary for the development of new tests, therapies, and cures. To address this, in 2008 the Genetic Information Nondiscrimination Act (GINA) was passed into law, prohibiting discrimination by employers and health insurers" (National Human Genome Research Institute, 2017).Find more about the NIH's work as you read the Genetic Information Nondiscrimination Act of 2008 that prohibits insurance companies and employers from genetic discrimination:Genetic Discrimination.ReferenceNational Institute of Health: National Human Genome Research Institute.

A karyotype is a picture of stained chromosomes arranged to show chromosome pairs. Abnormalities in chromosome number or size can be easily identified in a karyotype. Pedigree charts give a symbolic representation of phenotypic (observable) traits through a family. Using a pedigree, researchers can trace the pathway of a disease through families:Genetics Lab.ConsiderIf gene therapy was available to fix a gene before birth, do you think this might cross the lines of “unethical” research?InstructionsFor this assessment, you will complete a series of responses within the lab, complete an assessment at the end of the lab, and write a brief summary of your conclusion about the lab.To complete this assessment:Fill out the items requested in the lab.Complete the assessment at the end of the lab.Save a pdf of your responses and download it to your computer. You will have an option to download a pdf within the lab.Write a one-paragraph summary detailing new knowledge acquired in the lab.Attach both documents when submitting the assessment.Make sure that you read the Homework: Genetics Lab Scoring Guide prior to submitting your assessments to ensure you have met all of the expectations for this assessment.It is recommended that you review the scoring guide prior to completing the la as most work will be completed within the lab.Assessment Requirements Your summary should meet the following requirements:Length: Submit one double-spaced page.Written communication: Ensure written communication is free of errors that detract from the overall message.Standard formatting: Include one-inch margins, appropriate headers, and a title page.Font and font size: Use Times New Roman, 12-point font.Note: If you use assistive technology or any alternative communication methods to participate in this activity, please contact DisabilityServices@Capella.edu with any access-related questions or to request accommodations. Competencies MeasuredCompetency 1: Describe the organization of the human body. Explain the inheritance of an autosomal recessive trait by reading a pedigree.Explain the gender of the second patient in a lab scenario.Explain the results of the karyotype and how the chromosomal abnormalities affect the body systems.Explain the positive and negative ramifications of genetic testing.
