Species
Describe characteristics of generalist species
can thrive in wide variety, broad niche
Biotic factors
Competition, predation, disease, symbiosis
Draw a Type 1 survivorship curve

Stage 1
Pre transition
Total Fertility Rate
measures average number of children a woman suspected to have in her lifetime
Describe characteristics of specialist species
eats 1 thing, narrow niche, doesnt survive well
Temperature, water, sunlight, soil, climate
Draw a Type 2 survivorship curve
\
\
\
\
Stage 2
Early transition
infant mortality rate
measures the infant deaths per thousand live births
Describe characteristics of r-selected species
What is carrying capacity
Maximum population size a environment can sustain
Draw a Type 3 survivorship curve

\______________
Stage 3
Late transition
Doubling time
measures population growth rate
Describe characteristics of k- selected species
small number if offspring, high maturity age, higher competition, more parental care
How to find carrying capacity on a graph
Look for the maximum vertex
Which curve do r- selected species follow
Type 3
Stage 4
Post transition
what method is used to find doubling time?
Rule of 70
Name another type of species
Indicator, Keystone, Invasive, Endemic
What is population overshoot
When the ecosystem exceeds carrying capacity
Which curve do k- selected species follow
Type 1 or 2
Stage 5
Declining population
population momentum
To depict whether, a population has rapid, slow, zero, or negative growth rate
