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!


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
