• How are the boreal and tundra areas in the
• Arctic different from the boreal/tundra areas in
• Alpine areas?
• Seasonality
• B. Daily temperature change
• C. UV radiation
• D. All of the above

4
Aquatic systems - defined by physical factors
such as depth, temperature, water flow
5
From Miller 1993
6
thermocline
Oceans and lakes are usually thermally stratified
7
Aquatic systems Marine Pelagic zone (open
ocean) Deep sea Shallow benthos Coral
reefs Freshwater Lakes Streams/rivers
8
Shallow benthos
Pelagic zone
Deep sea
9
Biome Pelagic zone of ocean Climate Depends
on location generally warm and
well-lit Vegetation Phytoplankton Animals
Zooplankton, fish Net Productivity
Low Diversity Low
10
Diatoms photosynthetic protists
11
Zooplankton common herbivores and carnivores
of the ocean
12
Biome Deep sea Climate Extremely uniform
dark and cold Very high pressure Vegetation
None Animals Unusual things Net Productivity
Low Diversity Low but higher than pelagic zone

If no photosynthesis and no vegetation, what
supports the organisms that live in the deep
sea? What do they eat if they cant eat plants?
15
Biome Shallow benthos Climate Depends on area
relatively warm and well-lit Vegetation
Kelp forests and other seaweeds Animals
Urchins, starfish, sea cucumbers Net
Productivity Moderate to high Diversity
Moderate
16
Kelp forests
17
Biome Coral reefs Climate warm and
well-lit Vegetation Algae Animals Coral,
tropical fish Net Productivity High Diversity
High 25 of all marine species in 0.17 of
ocean area

Biome Lakes Climate Highly variable Vegetatio
n Phytoplankton, rooted plants on
edges Animals Zooplankton,

22
Shallow benthos
Pelagic zone
23
Biome Rivers/streams Climate Highly variable
less vertical variability than
lakes Vegetation Algae, rooted plants in large
rivers Animals Insect larvae, fish Net
Productivity Low to high Diversity Low to
moderate
24
More horizontal than vertical variability in
streams
