This document contains information about an introductory environmental science unit on ecosystems and populations, including: - The unit questions focus on understanding the value of diversity and how resilience is achieved through diversity. - Assessment tasks include an ecological survey lab and unit test. - Review tasks involve quizzes on ecosystems and communities and populations. - Several sections provide information on diversity, why it is important to measure, and challenges tracking species diversity in Brazil. - Additional passages discuss human population reaching 7 billion and the IUCN Red List categories for threatened species.

52. 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.

53. Conservation of Endangered Species
Extinct in the wild Endangered Near threatened
Critically endangered Vulnerable
What 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?

54. 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?
