1. What is Biological Diversity Bio diversity refers to the variety of life forms in an area. –Expressed as # of species in an area –Or # of genetic types in an area

2. Biodiversity The variety of the earth’s species, the genes they contain, the ecosystems in which they live and the ecosystem processes. Biodiversity is a vital natural resource

3. Basic Concepts of Biological Diversity Genetic diversity : –total # of genetic characteristics of a specific species, sub species or group of species. Habitat diversity : –the different kinds of habitat in a given unit area. Species diversity: –Species richness- total # of sp –Species evenness- the relative abundance of sp –Species dominance- the most abundant sp

5. 10 species; 100 ind, 10 ind each species

6. Species Diversity Merely counting the number of species is not enough to describe biological diversity.

7. Diversity Index A diversity index is a mathematical measure of species diversity in a community. Important to select area, understand what you are counting and be familiar with the organisms in order to do a DI What is the Diversity Index of that forest?

13. Diversity Lab DIRECTIONS: In this activity your "ecosystem" will be the school parking lot, and the "species" will be the different car models and colors. As a class, we will be comparing the species diversity of the student and staff parking lots. Count the number of different makes of cars (i.e. – Chevy, Honda, etc) in the student parking lot. (Consider models and colors to be “genetic diversity”) Count the number of different makes of cars (i.e. – Chevy, Honda, etc) in the staff parking lot. Calculate the diversity index using the equation below. Average the “D” of all the species to find the overall diversity of the parking lots.
