APES 11.6 and 11.7PLEASE PUT YOUR LAB BOOK BY THE FUME HOODTAKE OUT YOUR PARKING LOT LABLOG 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 42A = 38-42B = 34-37.5C = 29.5- 33.5D = 25.5-29Period 2 Class Average = 76% (31.9)Retakes for scores below 29

Short Answer out of 20A = 18-20B = 16-17.5C = 14-16D = 12-13.5Period 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/FragmentationInvasive SpeciesPopulation GrowthPollutionClimate ChangeOverexploitation

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’s1’s: Silver carp, Kudzu2’s: Scotchbroom, Cane toads3’s Brown tree snake, Lionfish4’s: Nile perch, Asian longhorn beetle

For your species:1. Where they’re from2. Current range3. How they spread4. Why they are so effective at

colonizing new areas5. Negative consequences to

native ecosystems
