Document Summary
By the end of this lecture you should be able to: Explain biodiversity in terms of species richness and species diversity. Describe the importance and benefits of biodiversity. Discuss conservation issues with respect to preserving biodiversity. Vista quiz: biodioversity and conservation must be completed before class starts. You can look at the absolute number of species and the abundance of each. Looking at both abiotic and biotic factors of the ecosystem. Increase in biodiversity = increase in primary production. Biological processes improve abiotic environment - increase with biodiversity. Loss of species diversity becomes a bit issue for us because humans rely on biodiversity for food, enjoyment and knowledge. ~1. 5 million species are cataloged which is not even comparable to how many species we are losing all the time: extinction. Losing a species permanently and this isn"t specifically a bad thing as it is a natural process however what is alarming is the rate of extinction.
