Measuring Population Biodiversity

Measuring Biodiverity

Open Ended

Warm up: How do you think scientists figure out how many species there are living within an ecosystem?

Learning Objectives. SWBAT:

• Define key terms such as Biodiversity, Species richness, and Species evenness

• Explain the importance of studying Biodiversity

• Identify different ways that biodiversity is studied. 

Ecosystem Richness

• Species richness is the number of different species represented in an ecological community, landscape or region.

• i.e. How many different species are present in a single ecosystem

• 
  

Ecosystem Evenness

• Species evenness refers to how close in numbers each species in an environment is.

• Mathematically explained as Diversity index.

• i.e. How do the populations of organisms compare? Is there more of one than another?
