2. Outline
The biome concept
- terrestrial
- aquatic
Survey of the biomes
Variability in Connecticut

3. Terrestrial biomes - defined by temperature
and precipitation

4. Aquatic systems - defined by physical
factors such as depth, temperature,
water flow

5. Terrestrial biomes of the world

6. Biome :
Climate:
Vegetation: The dominant types
Animals: A few of the charismatic ones
Net Productivity: rate of plant biomass production
Diversity: # of plant and animal species

8. Organisms in different biomes have
different adaptations depending on the selection pressures in that environment
What is an adaptation?

9. Which of the following gives the best example of an evolutionary change?
Over the last 1000 years, humans in Europe have increased in average height by 4 inches.
B. If you moved to the Andes mountains, after a year, your blood will transport 30% more oxygen than it does now.
C. Over the past 50 years, the frequency of antibiotic resistant strains of bacteria has increased.
