slide1. A Deep Dive
Calculating Biodiversity<br>
slide2. How do we use data to describe communities? Three main ways:
Species richness: The number of species present
Evenness: Uniformity of an ecosystem
Diversity: Number and relative abundance of species<br>
slide3. The number of different species in one area is called the species richness. If each different color represents a different species of sea star, what is the species richness?<br>
slide4. The number of different species in one area is called the species richness. Answer: 4!
Green, purple, pink, and blue<br>
slide5. Species evenness tells you about the relative abundance of different species. If all species are equally abundant, evenness is high. 2 2 2<br>
slide6. Species evenness tells you about the relative abundance of different species. If some species are very abundant and others are rare, evenness is low. 2 8<br>
slide7. Species evenness tells you about the relative abundance of different species. Would you say the evenness is high, medium, or low?<br>
slide8. A biodiversity index combines abundance and richness to describe the community. Species richness ÷ number of individuals = simple biodiversity index<br>
slide9. A biodiversity index combines abundance and richness to describe the community. Species richness ÷ number of individuals = simple biodiversity index
Try calculating the biodiversity of this group!<br>
slide10. A biodiversity index combines abundance and richness to describe the community. Species richness ÷ number of individuals = simple biodiversity index
Answer: 4 ÷ 10 = 0.4 10 individuals 4 species<br>
