1 ECOSYSTEM ECOLOGY II PP

2 PROPERTIES OF AN ECOSYSTEM
Species Richness Species Evenness Species- Area Effect

3 1. Species Richness: # of different types of species
Varies with latitude (closer to equator the more species) More sun, better climate stability

4 2. Species evenness: the abundance of each species

5 3. Measuring biodiversity
High richness and evenness = High biodiversity ↑species richness and ↑ evenness: ↑ stability (ability to withstand disturbances in the ecosystem)

6 4. Species- Areas Effect: larger areas contain more species than smaller areas

7 Sites A, C, and D have more richness
Sites A and C has the most evenness Which site has the highest biodiversity?
