Review of Chapter 1.
Define the term biodiversity.
explain the three levels of biodiversity.
Chapter 1:.
What were the main points?.
What did you learn?.
What is Biodiversity?.
Variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur.
Levels of Biodiversity.
Genetic Diversity.
Species Diversity.
Ecosystem Diversity.
Composition.
Numbers, names classification of species.
Measures of species diversity.
Measures of genetic diversity.
True Or False?.
Just over 10 million species have been identified by scientists. FALSE.
How many Species?.
1.7 million named.
100,000 well known.
10 mil estimated (not including microbes!).
True or False?.
Large plants, birds, and mammals make up 1/2 of the world's species. FALSE.
- 1,000,000 Arthropods!!.
- 270,000 Plants.
- 70,000 Fungi (More related to Animals than plan, share very little similarities with plants when put in the tree of life).
- 45,000 vertebrates (Birds are Reptiles).
- 40,000 Protists (Algae is a protist, not a plant), (Plasmodium is the protist that causes Malaria).
True or False.
All species on earth have been discovered. FALSE.
Measure of Species Diversity.
Richness - the number of species ( 5 Difference Colors).
Evenness: The relative abundance of species.
(2) (1).
Green - 4 1 .
Yellow - 4 2.
Blue - 4 9.
Red - 4 3.
Black - 0 1.
Disparity: The extent of differences between species.
Blue (Circles), Yellow (Triangles), Orange (Suns).
What are species?.
Hierarchical Classification.
Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.
Sciurus Carolinensis > Sciurus > Sciuridae > Rodentia > Mammalia > Vertebrate > Animalia > Eukarya.
What are species?.
Types or kinds of living things.
But, based on what characteristics?.
Similar Appearance?.
Ability to reproduce?.
Shared evolutionary history?.
All of the above? .
Species Concepts.
