Ecosystems & Populations

  1. 1. Ecosystems & Populations Introductory Environmental Science Canadian Academy MrT
  2. 2. Ecosystems & Populations Unit Questions: “What is the value of diversity?” Enduring Understandings: Resilience is achieved through diversityCriterion Assessment TasksD, E, F Ecological Survey LabC Unit TestReview tasks:- Quia Quiz: 7.1 Ecosystems & Communities- Quiz Quiz: 7.2 Populations
  3. 3. What is Diversity?
  4. 4. Why Measure Diversity?http://www.txchnologist.com/2012/noahs-scriveners-the-challenges-of-tracking-brazils-1-8-million-species

  7. 7. (now 7bn)
  8. 8. Rokko Island Ecological Survey What biotic and abiotic factors affect populations and distributions of a species? Investigate one factor and its effect on a population. 52
  9. 9. Conservation of Endangered Species Extinct in the wild Endangered Near threatened Critically endangered VulnerableWhat threatened species do you know about?Which category do you think they fit on the IUCN Red List (above)?What are conservationists and governments doing to protect them? 53
  10. 10. Save the Panda? Goal: Learn more about conservation of endangered species in the context of the panda Role: A team of researchers communicating issues of conservation ecology to their peers Audience: Yourself, your group and teacher Scenario: How do we make decisions about conservation and human impacts? Product: An instant expert sheet (this one) on conservation to be shared and used for study http://www.iucnredlist.org/ Work in a group of up to three students. Use the IUCN Red List database to find out more about conservation of pandas and other species. Find the natural range, determine the threats and uncover other species threatened in the same area. Discuss the benefits of whole-ecosystem conservation http://www.youtube.com/watch?v=W4nFwAvZ0OI as opposed to single-species efforts. What conservation techniques are most successful? 54Panda logo: http:wwf.org See what action you can take
