New cards
Exponential Growth
Population growth under unlimited resources
2
New cards
Exponential Growth Equation
dN/dt = rN
3
New cards
Exponential Growth Curve
J-shaped curve
4
New cards
Intrinsic Growth Rate (r)
Maximum per-capita growth rate under ideal conditions
5
New cards
Geometric Growth
Population growth in discrete breeding intervals
6
New cards
Geometric Growth Equation
Nt = N₀λᵗ
7
New cards
λ (Lambda)
Finite rate of population increase
8
New cards
λ > 1
Population increases
9
New cards
λ = 1
Population remains stable
10
New cards
λ < 1
Population decreases
11
New cards
Doubling Time
Time required for a population to double in size
12
New cards
Doubling Time Equation
t = 0.693/r
13
New cards
Carrying Capacity (K)
Maximum population size an environment can support
14
New cards
Logistic Growth
Population growth that slows as resources become limited
15
New cards
Logistic Growth Equation
dN/dt = rN(1-N/K)
16
New cards
Logistic Growth Curve
S-shaped curve
17
New cards
Inflection Point
Point of maximum population growth
18
New cards
Inflection Point Location
K/2
19
New cards
Negative Density Dependence
Population growth decreases as density increases
20
New cards
Examples of Negative Density Dependence
Competition, disease, predation
21
New cards
Positive Density Dependence
Population growth increases as density increases
22
New cards
Allee Effect
Positive density dependence at low population densities
23
New cards
Source of Positive Density Dependence
Easier mate finding and improved survival at higher densities
