APES 11.6 and 11.7 PLEASE PUT YOUR LAB BOOK BY THE FUME HOOD TAKE OUT YOUR PARKING LOT LAB LOG IN TO A COMPUTER FOR LATER

Learning Targets

Parking Lot Biodiversity  Be prepared to share:  Which parking lot was more diverse? How do you know?  How could the Simpson Index be used in a real ecosystem?

Unit 4 Test Results Multiple Choice out of 42 A = B = C = D = Period 2 Class Average = 76% (31.9) Retakes for scores below 29 Short Answer out of 20 A = B = C = D = Period 2 Class Average = 73.7% (14.75) Retakes for scores below 14 Retakes must be done by next Friday, 11/13

Test Corrections 1. Tell me why your multiple choice answer was wrong. Good: my answer, that land at the equator has the highest albedo, is wrong because snow has the greatest albedo SINCE IT REFLECTS SO MUCH LIGHT. Bad: my answer, B, is wrong because I just forgot to study that. 2. Re-answer short answer.

EcoColumns Data Collection  pH, temperature with probes  Nitrate, phosphate with blue test kits  D.O. with glass ampule kit  Water it with treated water and bubble air in for fish (if you want)  Record what you added/subtracted Next week: what do all these #s mean? We will get some background info. and start to make sense of what’s going on.

Invasive Species  Remember, Invasive Species are one of the 6 threats to biodiversity: Habitat Destruction/Fragmentation Invasive Species Population Growth Pollution Climate Change Overexploitation

Native vs. Alien  Native Species = species that live in their historical range; thrived there due to natural selection  Endemic species = only live in a small area; at greatest risk (i.e. hot springs fish)  Alien Species = species living outside it’s historical range  Invasive Species= alien species that spreads rapidly across large areas

Invasive Species  Example: Zebra Mussels  Native to Black Sea and Caspian Sea (Europe, W. Asia)  Cargo ships carrying seawater came over to St. Lawrence River and the Great Lakes in the 1980’s and dumped their unneeded water  Zebra mussels colonized the Great Lakes, killing off native mussels  Can multiply so fast (1 female = 30,000 eggs) that they clog industrial pipes!

Your Turn!  Number off by 4’s 1’s: Silver carp, Kudzu 2’s: Scotchbroom, Cane toads 3’s Brown tree snake, Lionfish 4’s: Nile perch, Asian longhorn beetle  For your species: 1. Where they’re from 2. Current range 3. How they spread 4. Why they are so effective at colonizing new areas 5. Negative consequences to native ecosystems

Due Next Time  Your notes on modules 15, 16, 18, 20  End of module Multiple Choice  Key terms not already included in notes  Invasive species are NOT homework
