What Is Community Structure?
2
What Determines Species Diversity? Some Examples/Graphs
3
Types of Species and Their Roles
1. Native (eg. deer)
2. Non-native, incl. invasive and alien (eg. large mouth bass)
3. Indicator - sensitive to environmental conditions, indicator of habitat's wellbeing
4. Keystone - play critical ecological roles (eg. beaver, atlantic salmon)
5. Foundation - create and enhance habitats (eg. beaver, elephant)

What is resource partitioning? Graph?
6
What makes up ecological stability?
7
What is the precautionary priciple?
8
What are population dynamics? Formula
9
Types of population dispersion
10
What factors dictate population size?
11
Types of population growth (how a single population grows)
12
draw graphs of population overshoot then crash (one for massive overshoot, crash and die out, one for small overshoot, small crash, then stablizes)

Human Impacts on Natural Systems
• Habitat degradation and fragmentation
• Ecosystem simplification
• Use and waste of primary resources
• Genetic resistance
• Predator elimination
• Introduction of non-native species
• Overharvesting renewable resources
• Interference with ecological systems
• Creating fossil fuel dependent systems

Do communities have one species or several
several

What factors cause communities to change?
succession (inclu. evolving) and disturbance
