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?

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
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!
