Ecology
Population Ecology
Size
Number of individual
Density
Number of individual / unit area
Dispersion
Pattern of spacing among individual
Clumped
Uniform
Random
How to quantify?
Quadrat
Pitfall trap
Mist trap
Live trap
Components
Population
Different species in the same region
Community
Different population in the same region
Ecosystem
Community + non-living environment
Organism's interaction
Producer -> Consumer -> Decomposer
Competition
Both negative
Symbiosis
(at least one benefits)
Predation,
herbivory,
parasitism
One benefits, the other harmed
Commensalism
One benefits, the other unaffected
Mutualism
Both benefit
Growth / Decay
Linear
Rate of increase/decrease
remain constant
with time
y=a+bx
a - Initial value
b - Growth / Decay value
x - Number of time interval
Linear graph
Exponential
Rate of increase/decrease
change proportionately
with time
y=a(b)^x
a - Initial value
b - Growth/decay rate/factor
x - number of time interval
Exponential graph: J-shape
Logistic graph: S-shape; carrying capacity reached
