1. Biodiversity and Conservation7
CHAPTER
Placeholder opening page, but maybe we can duplicate the look of the SE chapter opener page by using the same fonts and colors (and maybe that Ch 14 icon?)

2. Brainstorm!
Estimate how many different types of species are on earth, including plants, animals, fungi, and microorganisms.

3. Scientists have identified 1.7 to 2 million species to date.
HOWEVER, scientists estimate the total number of species on earth is between 3 million to 100 million!!!

4. Lesson 7.1 Our Planet of Life
There are more known species of insects than any other form of life. Among known insect species, 40% are beetles.

5. Lesson 7.1 Our Planet of Life
Biodiversity
Describes the variety of life across all levels of ecological organization
Includes three types:
Ecosystem diversity
Species diversity
Genetic diversity
Genetic Diversity
Species Diversity
Ecosystem Diversity

6. Lesson 7.1 Our Planet of Life
Ecosystem Diversity
The number and variety of ecosystems in a given area
Brainstorm: List the ecosystems found in Florida. Does Florida have a high Ecosystem Diversity?

7. Species Diversity The number or variety of species in a given area
Lesson 7.1 Our Planet of Life
Species Diversity
The number or variety of species in a given area
Speciation increases biodiversity!
Extinction decreases biodiversity!

8. Lesson 7.1 Our Planet of Life
Genetic Diversity
The differences in DNA among individuals within a species
The more genetic diversity in a population, the better the chance for survival because it provides the raw materials for adaptation

9. Lab: How genetically diverse is 1C-310??
Lesson 7.1 Our Planet of Life
Lab: How genetically diverse is 1C-310??
Work with your table.
To find percentage, take the number in the first column (Group Results) and divide it by the second column (Group Total).
EXAMPLE: 2 people have curly hair / 4 people in the group = 50%

10. Other Benefits of Biodiversity
Lesson 7.1 Our Planet of Life
Other Benefits of Biodiversity
Agriculture: Wild strains are cross-bred with related crops to transfer beneficial traits.
Medicine: Organisms contain compounds that are useful for treating disease.
Ecotourism: Environmentally responsible tourism is a source of income for many nations.
The yew tree, an original source of Taxol, a cancer-fighting drug
Did You Know? Of the 150 most prescribed drugs in the United States, 118 originated in nature.

11. Causes of Biodiversity Loss
Lesson 7.2 Extinction and Biodiversity Loss
Causes of Biodiversity Loss
Habitat change and loss
Invasive species
Pollution
Overharvesting
Siberian tiger

12. Habitat Change and Loss
Lesson 7.2 Extinction and Biodiversity Loss
Habitat Change and Loss
Greatest cause of biodiversity loss
Organisms, adapted to their habitat, decline in population when the habitat changes.
Habitat fragmentation: Patches of suitable habitat surrounded by unsuitable habitat
In general, larger habitat fragments can support greater biodiversity than smaller fragments.
Did You Know? Habitat change or destruction is the primary cause of population decline in more than 80% of threatened birds and mammals.

13. Invasive Species, Pollution, and Overharvesting
Lesson 7.2 Extinction and Biodiversity Loss
Invasive Species, Pollution, and Overharvesting
Invasive species can out-compete and displace native species.
Harmful chemicals and materials that make their way into habitats can poison people and wildlife.
Occasionally, species can be driven toward extinction by hunting or overharvesting by humans. Examples include Siberian tigers and passenger pigeons.
Once common in North America, the passenger pigeon is now extinct.

14. Climate Change Increasingly becoming a factor in biodiversity loss
Lesson 7.2 Extinction and Biodiversity Loss
Climate Change
Increasingly becoming a factor in biodiversity loss
Unlike the other factors, climate change will have a potentially global effect on biodiversity.
Did You Know? Scientists predict that a 1.5–2.5C global temperature increase could put 20–30% of plant and animal species at increased risk of extinction.

19. Lesson 7.3 Protecting Biodiversity
Just 2.3% of the planet’s land surface is home to 50% of the world’s plant species and 42% of its vertebrate animal species.

20. Biodiversity Hotspots
Lesson 7.3 Protecting Biodiversity
Biodiversity Hotspots
The “hotspot approach” focuses attention on areas where the greatest number of species can be protected with the least effort.
Hotspots have:
At least 1500 plant species found nowhere else in the world
Already lost 70% of their habitat as a result of human activity
The 34 biodiversity hotspots are home to 50% of Earth’s plant species and 42% of terrestrial vertebrate species.
Northern Pintail ducks, Honshu, Japan Japan is one of the world’s biodiversity hotspots.

22. Biodiversity Hotspots Glogster
Lesson 7.3 Protecting Biodiversity
Biodiversity Hotspots Glogster
 Go to  
Make a glogster and include the following information:
Location of the hotspot and type of ecosystems found there.
Describe at least one endemic plant species and one animal species found there
Describe the socio-economic conditions (pre-industrial, transitional, industrial, post-industrial)
Human induced and/or natural reasons why species biodiversity is decreasing in that region
What is being done to protect this hotspot
Any interesting information you found about the area (AKA your choice!)
LOTS of pictures and color!!
