Measuring Species Diversity

How Can We Measure Species Diversity?

This post will go through measuring species diversity for QCE Biology.

3.1.1 – Biodiversity

  • Determine diversity of species using measures such as species richness,
    evenness (relative species abundance), percentage cover, percentage
    frequency and Simpson’s diversity index
  • Use species diversity indices, species interactions (predation, competition,
    symbiosis, disease) and abiotic factors (climate, substrate, size/depth of area)
    to compare ecosystems across spatial and temporal scales
  • Mandatory practical: Determine species diversity of a group of organisms
    based on a given index

 

What is The Index of Species Diversity?

Simpson’s Index of Diversity is a measure of diversity for habitats and can also describe species abundance and magnitude. This video will go through Simpson’s index of diversity and also some practice calculations.

 

This video is another explanation of Simpson’s Index of Diversity.

 

This video will go through species richness and evenness.

 

How Do Species Interact?

This video will go through the various modes in which species can interact, such as predation, symbiosis and etc.

 

This is a video detailing the importance of biodiversity.
