Lesson 2: Speciation and Diversity in Appalachia

 

Student Objective:

This lesson highlights the diversity of Appalachian species, particularly salamanders, explores how speciation occurs through geographic isolation, and introduces different ways that species diversity can be measured. 

Students will:

      • Recognize the unique features of Appalachia that make it a global species-diversity hotspot for salamanders.
      • Evaluate several different stressors faced by salamander populations in Appalachia.
      • Understand how speciation can occur through geographic isolation.
      • Differentiate between different methods for measuring species diversity.
