5.1 Vanishing Species

• Biodiversity: the diversity of plant and animal life in a particular habitat (or in the world as a whole); "a high level of biodiversity is desirable"

• How many different types do you have?

Biodiversity

• Makes an ecosystem more resistant to change or more able to survive a change in conditions. Not all species may survive, but some should.

• If a niche goes away, so do all the organisms that used it.

• Diversity makes an ecosystem more stable

• Edge Effect (Ecotone)

Human Benefits of biodiversity

• Beauty

• Drugs

• Ecological stabilty

• No plants, no oxygen

• No ocean, no moderated temperature on Earth

Threats to Biodiversity

• Habitat loss

• Habitat fragmentation

• Habitat degradation

Habitat degradation

• Ozone layer• Global warming-does it occur?• Acid precipitation• Water pollution• Land pollution• Groundwater pollution• Land use• Exotic pets

Global Warming

• On Nicenet a question is posted:• The first question is "Does Global Warming

Exist?

• You must research the topic and give your opinion. You must give the link or quote or source that helped you form this opinion. You must respond to 3 other posts. MIND YOUR MANNERS!!! Serious polite responses are required

Nicenet

• You will be graded. You have until Monday to respond with the answer to question 1 and Until next Friday to respond to at least 3 posts.

Paramecium Lab

• Counting

• Stir your cultures.

• Take one drop out and make a slide

• Move to the 4 corners of the drop (and cover slide, we will use the small ones) and count the paramecia there.

• Move to the dead center and count. Record all counts

Paramecium Lab

• There should be two counts done on each culture (two drops looked at). Clarify in your group, who does what.
