Ecology Questions

Please answer the following questions in a 200-word response minimum. Try your best to reference the text I will message you privately for how to access the text book.

  1. Discuss the current view  how the abiotic synthesis of polymers led to the formation of life on earth.

 

  1. Explain how ecologists define species diversity. What types of information must be gathered by scientists to assess the degree of diversity of an ecological community?

 

  1. Would removing an endangered species out of their habitat to preserve them if their ecosystem is allowed to disappear? Explain.

 

  1. One area of concern to scientists are ecosystems. Ecosystems can not be recreated in a laboratory study. Instead, field studies are used as a substitute for the laboratory but field observations are lacking in the ability to control variables which exist.

What caveats would you state to a lay person regarding the results of a field study

 

  1. One consideration for conservation of a species is the role of competition between and among populations of species. What is interspecific competition and discuss the impact competition has on the structure of an ecological community.

 

  1. Two concepts often discussed in ecology are a community and a population. Compare and contrast a community and a population.

 

Please participate (respond) to the classmate’s answers with POSITIVE notable and educational input. (200 word minimum Reponses)

 

  1. Danielle: A community of organisms refers to all of the populations of organisms living close enough together to interact.  Species diversity refers to the variety of species that makes up a community, and includes two facets: species richness, or the number of separate species within a community, and the relative abundance of each of those species.  Plant and animal diversity affects the community as a whole; where plant diversity is low, it may attract a smaller variety of animals specific to, for instance, the particular edible plants and habitable trees in the community.  Greater diversity also decreases the risk of disease by pathogens; monocultural agriculture, for instance, is more susceptible to mass disease by a pathogent to which the crop is not resistant than is a crop field in which several varieties of crop are planted, where some may be resistant and some may not be.

  1. Tyler: When looking at life on Earth and the abiotic synthesis of polymers they are three stages to consider. The first step is the abiotic synthesis of small organic molecules in the origin of life, which then leads us to the abiotic synthesis of polymers. Enzymes catalyze in a cell that then join monomers that build polymers, which there are concerns into whether or not this could have happened. One of the key steps in the origin of life is the isolation of a collection of organic molecules within a membrane enclosed compartment, which is called formation of protocells. Once this happens we move to self replicating RNA, which when RNA is added to a RNA monomer new RNA molecules complementary to parts of the starting RNA sometimes assemble then monomers would adhire to clay particles and this is where the use of RNA world came into context. (Reece, Taylor, Simon, & Dickey, 2012).

Virtual Ecology Lab: Invasive Species Worksheet

Virtual Ecology Lab: Invasive Species Worksheet

Learning Goal: To learn how an invasive species can affect an ecosystem.
Prerequisite Knowledge: Before beginning this lab, you should be familiar with these concepts:
•    the definition of invasive species
•    the types of interactions that occur between different species in an ecosystem
Introduction: Ecosystems are webs of intricately balanced interactions. But what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s resources? In this lab activity, you will determine how an invasive species, the Burmese python, affects other species in the Florida Everglades.

Part A
Normal conditions (no pythons)
Enter the Ecology Lab Room by clicking the button. Then follow the Lab Procedure.

Lab Procedure
1.    Four species appear in the Species Tracking box in the lower left: cougar (or Florida panther), house mouse, Burmese python, and red-eared slider. Note that the python population is set to 0 because in this first simulation, they have not yet been introduced to the ecosystem.
2.    Click the green play button on the Controller, the device sitting on the floor of the Lab Room.
3.    Let the simulation run until 20 years have passed, as displayed by the graphs that appear in the data window on the right side of the screen. (Years are shown on the x-axis.) The speed of the simulation can be accelerated or slowed by clicking the + and – buttons.
4.    After 20 years, pause the simulation by clicking the red button on the Controller.
5.    Click the SAVE button in the upper right corner of the data window to save the data to the Lab Book.
6.    Then click on the Lab Book (on top of the Controller) to open the saved data. Change the data’s title from “Tropical Forest” to “Normal.”
Describe the growth patterns of the mouse, cougar, and red-eared slider populations when pythons are not present.

ANSWER:

Part B
Introduce Burmese pythons
The Burmese python is a species of snake native to Southeast Asia. In Florida, some people who bought Burmese pythons as pets ultimately released them outdoors. The species took hold in the wild, especially in the Everglades.
7.    Click the TIME button at the bottom of the Controller to reset the simulation.
8.    In the Species Tracking box, make sure that the fields next to the +/- Population button are set to +80 and Python, Burmese.
9.    Run the simulation again by clicking the green play button.
10.    But this time, add 80 pythons after 10 years have passed by clicking the +/- Population button when the simulation reaches the 10-year mark.
11.    Let the simulation run for 30 more years. Then pause the simulation at Year 40.
12.    Again, save the data to the Lab Book. Edit the data’s title to “Python Invasion.”
Describe the growth of the Burmese python population immediately after they were introduced.

ANSWER:

Part C
What happened to the populations of the other animals?

ANSWER:

Part D
Think it over
Suggest one reason why the introduction of Burmese pythons to this ecosystem may have caused the effects you observed.

ANSWER:

Part E
Remove Burmese pythons
Now try controlling the Burmese python population.
13.    Click the TIME button at the bottom of the Controller to reset the simulation.
14.    In the Species Tracking box, make sure that the fields next to the +/- Population button are set to +80 and Python, Burmese, and that the fields next to the Catastrophe button are set to -80% and Python, Burmese.
15.    Run the simulation again by clicking the green play button.
16.    When the simulation reaches the 10-year mark, click the +/- Population button to add 80 pythons.
17.    When the simulation reaches the 30-year mark, click the Catastrophe button to wipe out 80% of the python population.
18.    Let the simulation run for 10 more years. Then pause the simulation at Year 40.
19.    Again, save the data to the Lab Book. Edit the data’s title to “Python Removal.”
What happened to the cougar and Burmese python populations when 80% of the Burmese pythons were removed?

ANSWER:

Part F
Think it over
What do your observations reveal about the challenges involved in fighting invasive species?

ANSWER:

Part G
Based on your observations of Burmese python population trends, recommend a way managers could fight the Burmese python invasion in the Everglades. Explain your reasoning.

ANSWER:

Part H
Would you recommend introducing another nonnative species from Southeast Asia that is known to prey upon the Burmese python or its eggs? Explain.

ANSWER:

Part I
Not all invasive species are predators.
Which of the following characteristics would help any nonnative species, regardless of its place in the food chain, become invasive? Select all that apply.

ANSWER:

____ reproduce fewer offspring in new environment

____ grow and reproduce quickly in new environment

____ lack adequate space in new environment

____ outcompete native species for resources in new environment

____ have no natural predators in new environment

DEFINING AND MEASURING BIODIVERSITY


DEFINING AND MEASURING BIODIVERSITY
Now that you have a solid understanding of the study of ecology and how scientists measure biodiversity, let’s continue to develop the relationship between economics and the natural world. We start with the question:

Why do we care about biodiversity and the natural world?
To complete your SLP assignment:

Read the following article available in the Trident Online Library:
Public attitudes: What’s the use? (2013, Sep 14). The Economist, 408(8853):6.

Describe the relationships between the shift in “humanity’s approach to the natural world” and the “three great intellectual movements of recent times.”
Research an example in your region or an example of interest globally, where biodiversity has been affected in a way that has impacted you or the people nearby. If you use one of the examples in the article, provide additional related articles to dive more deeply into the situation.

Assignment 2: Comparative Research on Cross-Cultural Families


Assignment 2: Comparative Research on Cross-Cultural Families

(70 points)

Students will choose a cross-cultural* research article from a Family Studies journal (only choose from Family Relations, Journal of Marriage and Family, or Journal of Comparative Family Studies) other than from what is already an assigned reading for this course. All these journals are available in the www.wmich.edu/library. Know how to use this resource.

Based on that article, students will complete the Comparative Research on Cross-Cultural Families Form below.

*Note: Cross-cultural research articles are papers that have participants who are from different cultural backgrounds, have a methodology part, and have results and discussion sections. Please take note that the article that you choose should be comparative, meaning it compares the samples or participants with culture as a factor.

Your Name:  ___________________________________________________

In answering the questions below, do not lift words or copy exactly the sentences in the article. PARAPHRASE or use your own words to summarize the ideas from the article.

  1. Reference or bibliographic entry of your selected article in APA style (see example in the first assignment guidelines):
  1. What are the aims and/or research questions of the study?

 

  1. What concepts or ideas did the authors want to study? How were they defined in the study? Read through the literature background or the introduction part.

 

  1. Describe the participants of the study. Since you are supposed to choose an article of a cross-cultural study on families, the participants for this study should have different cultural backgrounds. What are these cultural backgrounds? What are the demographics of the participants?

 

  1. What is the authors’ methodology? How did the authors collect their data? What are the measurements or research tools that they used?

 

  1. What kind of analytical procedures did the authors use? Describe each as to how they can answer the research questions or achieve the aims of the study.

 

  1. What are their general findings and conclusions?

 

  1. After the findings and conclusions, what recommendations were made by the researchers?

 

  1. What learning did you gain from this assignment or from reading this kind of a paper?

 

Grading:

  1. Complete answers to each of the 9 questions (7 pts each) = 63
  2. Writing quality (spelling, grammar, sentence construction, etc.) = 7

TOTAL: 70 Points
