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

Terrestrial biomes - defined by temperature and precipitation

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

Terrestrial biomes of the world

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

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

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.

Outline The biome concept Survey of the biomes Variability in Connecticut

Biome : Tundra Climate: Short, cool summers Long, very cold winters Permanently frozen soil (permafrost) Vegetation: No trees Very short vegetation Animals: Caribou, lemmings, artic fox Net Productivity: Low Diversity: Low

Why are there no trees in the tundra? A. permafrost B. shallow snow cover C. short and cool growing season D. all of the above

Biome : Boreal forest Climate: Cold Low – moderate precipitation Vegetation: Spruce, fir Animals: Moose, wolves, elk, bear Net Productivity: Low Diversity: Low

Biome : Temperature seasonal forest Climate: Warm summers, cold winters Moderate precipitation Vegetation: Mostly deciduous trees Some conifers (pine, hemlock) Animals: Deer, turkey, skunk Net Productivity: Moderate Diversity: Moderate

As spring arrives, perennial herbaceous plants will begin to push out of the ground in deciduous forests around here, but not in the coniferous forests. This early growth ensures that the herbs…. A. Get enough light to grow B. Get enough water to grow C. Get enough nutrients to grow D. Avoid insect herbivores

Biome : Temperate rainforest Climate: Cool summer Mild winter High rainfall Vegetation: Large coniferous trees Animals: Bear, salmon, spotted owl Net Productivity: Moderate Diversity: Moderate

Biome : Grasslands Climate: Hot summers Cold winters Vegetation: No trees Grasses and herbaceous plants Sagebrush Animals: Prairie dog, antelope, bison Net Productivity: Moderate Diversity: Moderate

Biome : Temperate woodland/shrubland Climate: Cool, moist winters Hot, dry summers Vegetation: Fire resistant shrubs Animals: Migratory birds Browsers – deer, sheep, goat Net Productivity: Low Diversity: Variable (never high)
