3. Reminders of Important Dates
Open-notes test on evolution & Species interaction tomorrow, Thursday, october 5, bring all relevant notes with you!
1st Quarter Progress report grades close TOday, October 4,
If you are failing a class, you have NO more days to improve your grade before progress report grades are finalized!
By the close of business today (~4 pm), your progress report average cannot change; however, your 1st quarter grade is still being generated so keep working hard!

4. Today’s Objective
Students will know how invasive species impact ecosystems by taking notes, performing a close reading and completing a worksheet and answering exit ticket questions.
Mastery: 2/3 or better on the exit ticket questions; 23/33 or better on the Ecological Pyramid P.O.G.I.L.

5. New Vocabulary Words – Invasive Species

10. Essential Question What are invasive species?
How do they become invasive?
What is the impact on human activities?

11. What is an invasive species?
Exotic Species are species that occur outside of their natural ranges because of human activity.
An exotic species becomes invasive when it becomes established in its new environment and out competes native species
Allow students to share their thoughts on invasive species. Correct any inaccuracies. If possible, list on the board as students mention them and before you correct inaccuracies, ask their peers if they think any should be removed from the list.

12. Types of invasive species
Animals
Plants
Pathogens

13. What is the problem with an invasive species?
Can cause an imbalance in the natural environment
Out compete native organisms for resources
Change abiotic factors
Threaten agriculture
Endanger the health of plants and animals
Give an example of each imbalance.
Out compete-
Change abiotic-
Agriculture-
Endanger Health-

14. How do invasive species travel?
Humans
Wind
Water

15. Humans- Can simply carry a organism.
Some invasives can stow away on a ship or plane.
Wind- Seeds can be carried great distances.
Water- Organisms can be transported on natural “rafts”

16. Examples of Invasive Species:
Zebra mussel
Kudzu
Giant Hogweed Asian Tiger Mosquito
Lionfish

17. Zebra Mussel(2) Originally from the Caspian and Black Sea.
Introduced to the Great Lakes in 1988.
Cause many problems:
Can harm other fresh water mussels
Can block intake pipes for power plants
Can cause problems for recreational activities.

19. Kudzu

20. Kudzu Also called Japanese arrowroot
It is a climbing, coiling, and trailing vine native to southern Japan and south east China.
It occurs as an invasive species in the U.S. (W.W.II), it is considered a harmful weed that climbs over trees or shrubs and grows so rapidly, it kills them by heavy shading.
The plant is edible.

21. Giant Hogweed(2) Native to Eurasia (Europe and Asia)
Introduced to the United States in 1917.
Originally used as an ornamental plant
It out competes other plants for resources.
It produces a toxic sap.

23. Asian Tiger Mosquito(2)
Originally from Asia.
Introduced to Hawaii in the late 1800’s.
Continental United States in 1985.
Can be a vector for disease.
Ex. West Nile Virus
Zika Virus
Chikungunya Fever

24. Asian Tiger Mosquito (5)

25. Lionfish(2) Native to the Pacific Ocean
Introduced to the water around the United States in 1992 through the aquarium trade.
Preys on native species.
Has poisonous spines.

27. What can you do?
Obey the rules. Do not transport plants and animals when you travel.
Never release pets into the wild.
Learn about invasive species in your area for identification.
Use native plants.
