Describe original observations of researchers.
Describe the study in detail:
·Research questions of study ·Hypotheses ·Variables in study
Discuss research findings.
·Include a brief, general overview of how ecologists use evidence and observation to quantify results before going in to the specific findings of this case study.
Discuss evolution and its relationship to natural selection.
·What role do they play in ecology?
·What role do they play specifically in the case study chosen?
Propose a follow-up study based on the case study. Briefly address the following questions:
·What variables would you alter?
·What additional findings might you expect to discover on aspects of evolution or natural selection in your proposed study?

BIO 315 WEEK 2 DQ 2


Define the terms fundamental niche and realized niche. How does competition relate to George Evelyn Hutchinson’s concept of niches? How can niche differentiation or complementary experiments explain aspects of evolutionary theory?

BIO 315 WEEK 2 DQ 3


Describe the three main types of predator defined in ecology. How does an understanding of fitness, abundance, and foraging behavior help us understand predation? How does environmental patchiness or fragmentation affect predator–prey populations?

BIO 315 WEEK 2 LEARNING TEAM EXERCISES

After reading Ch. 1 of Essentials of Ecology, create an outline of the main interactions that happen between organisms, populations, and communities in an assigned ecosystem. Develop an outline and suggest additional interactions that might be important.
Examine the importance and applicability of this week’s concepts to each team member and to society in general.
·Post your team’s outline from this exercise via the Assignments link. Briefly describe how this activity applied to the weekly concepts.
Post a 150- to 200- word summary from your team’s examination and discussion of the weekly concepts exercise via the Assignments link.

BIO 315 WEEK 2 INDIVIDUAL ASSIGNMENT ENVIRONMENT, RESOURCES, AND COMPETITION


Resources: University of Phoenix Materials: Temperature and Precipitation, Intraspecific Competition, and Interspecific Competition located on your student website
Imagine you are an ecologist studying ecosystems. In this assignment, you are given a set of data to study.
Review the Temperature and Precipitation data, Intraspecific Competition data, and Interspecific Competition data located on your student website.
Analyze the data provided in three graphs.
Environment, Resources, and Competition Presentation:
Prepare a 10- to 15-slide Microsoft® PowerPoint® presentationthat answers the following questions:
·What are the major characteristics of the environment of the chosen ecosystem?
·How do these characteristics affect the animals, plants, and their resources living in the environment?
·Review the temperature and precipitation data. From the data, what can you determine about the role of precipitation and temperature in biomes?
·Review the Intraspecific Competition data. How is the predator community affected by low numbers of prey? How do high numbers of predators affect the prey community? What are some possible effects on other species?
·Review the Interspecific Competition data, what behavioral data might be inferred from this graph? What factors might be responsible for the success of the older mothers’ offspring? Propose a scenario that might explain the data recorded. How might interspecific competition affect the reproductive success?
·What implications can you infer from the three graphs about the relationship between plants and animals?

BIO 315 WEEK 3 DQ 1


What are some ways ecologists define populations? What are some of the factors that regulate populations? What challenges do ecologists encounter when studying populations?

BIO 315 WEEK 3 DQ 2


What is demographic stochasticity? Why are small populations more susceptible to extinction from demographic stochasticity than larger populations? Why is demographic stochasticity important to biologists?

BIO 315 WEEK 3 DQ 3


What is primary and secondary production? What are the limiting factors on primary production in terrestrial and aquatic ecosystems? Why is it important for an ecologist to be able to understand the energy pathways through trophic levels?

BIO 315 WEEK 3 DQ 4


What is a biogeochemical cycle? Describe how the hydrological cycle transports water through ecosystems. What are some examples of both benign and disruptive human contributions to biogeochemical cycles?

BIO 315 WEEK 3 INDIVIDUAL ASSIGNMENT YEAST CULTURE LAB


Resources: University of Phoenix Materials: Lab Report Outline, Yeast Lab Worksheet, and Yeast Lab Spreadsheet located on your student website
Review the Yeast Lab Worksheet. It contains images of four yeast samples that were observed at 0, 24, 48, 72, and 96 hours.
Count the number of yeast cultures observed at each interval.
Record the data on the Yeast Lab Spreadsheet and analyze the graphs.
Write a lab report of 1,050- to 1,400-words following the Lab Report Outline provided on your student website. Address all points listed in the outline.
Format your lab report consistent with APA guidelines

BIO 315 WEEK 3 LEARNING TEAM EXERCISES


Ecosystem Stability
·Complete the following:
Identify producers and consumers in your native biome and answer the following questions:
·How would removing a producer affect that biome?
·What if a consumer is removed?
·How are the results different?
·In what situation would an ecosystem be unaffected by the removal of producer or consumer?

BIO 315 WEEK 4 DQ 1


Define the following terms: biome, mosaic, and patch. What role does scale play in the study of ecology? Why are aquatic ecosystems classified differently than terrestrial biomes?
