5. Biodiversity
What does “Bio” mean?
Life

6. What does “Diversity” mean?
Biodiversity
What does “Diversity” mean?
Diversity = Variety

7. Biodiversity
*Biodiversity is the variety of life in an area that is determined by the number of different species in that area.
*Biodiversity increases the stability of an ecosystem and contributes to the health of the biosphere.

8. *There are 3 components of biodiversity:
Genetic
Diversity
Species Diversity
Ecosystem Diversity

9. Genetic Diversity
*Genetic Diversity- the variety of genes or inheritable characteristics present in a population Chihuahuas, beagles, and Rottweiler's are all dogs—but they're not the same because their genes are different.
Beagle
Chihuahua
Rottweilers

10. Species Diversity
2. *Species Diversity- the number of different species and the relative abundance of each species in a biological community. For example, monkeys, dragonflies, and meadow beauties are all different species in the same community.
Golden Skimmer
Meadow Beauty
Saki Monkey

11. Ecosystem Diversity
3. *Ecosystem Diversity- the variety of ecosystems that are present in the biosphere.
Prairies, Ponds, and tropical rain forests are all ecosystems. Each one is different, with its own set of species living in it.
Paines Prairie
Florida Sand hill Pond
Hoh Rain Forest

18. The Importance of Biodiversity
*Aesthetic and Scientific Value: The value of beauty and scientific discovery cannot be measured, but are extremely important to life on Earth.
*Direct Economic Value: Maintaining biodiversity has a direct economic value to humans. Humans depend on plants and animals for food, clothing, energy, medicine and shelter.

19. The Importance of Biodiversity
*Indirect Economic Value: a healthy biosphere provides many services to humans and other organisms that live on Earth.
Examples:
Green plants provide oxygen
Water cycle provides clean water

20. The Importance of Biodiversity
Your Turn:
Think of an environment you have been to, or live in. What different species of plants and animals have you seen? How do they depend on each other? What are some examples of genetic diversity and species diversity in that environment? Write a paragraph that answers these questions.

21. Should we be concerned about biodiversity?
What we know: The Earth is losing species at an alarming rate
In the past 500 years, we know of approximately 1,000 species that have gone extinct 

22. *Threats to biodiversity
*Overexploitation
*Habitat Loss
*Habitat Fragmentation
*Pollution
*Introduced Species
*Global Climate Change

23. Endangered Species
An Endangered Species- is a plant or animal that is in danger of becoming extinct.
List of endangered species
A Threatened Species- plants or animals that may become endangered in the near future

24. Extinct Species
Extinct species- are plants or animals that once lived on Earth that have completely disappeared.
The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. It stood about a metre (3.3 feet) tall, weighing about 20 kilograms (44 lb).
The dodo was first mentioned by Dutch sailors in By 1681, all dodos had been killed by hungry sailors or their domesticated animals.
The extinction of the bird, within 80 years of its discovery, made people realise for the first time that humans could induce the extinction of plants and animals.--- …
