sci.lotka-volterra-predator-prey Calculator
Calculates predator-prey population oscillations using the Lotka-Volterra equations: dN/dt = αN − βNP and dP/dt = δNP − γP. Lotka-Volterra cycles have constant amplitude — in practice, stochastic events and spatial structure cause dampening and irregular cycles.
Inputs
Prey Population
Reference formula or conversion factor shown for context.
Predator Population
Reference formula or conversion factor shown for context.
Prey Growth Rate
Annual percentage increase. Enter as a percentage. Compound growth is exponential — small differences in rate become enormous over long periods.
Predation Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Predator Efficiency
Reference formula or conversion factor shown for context.
Predator Death Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
prey growth rate (dN/dt)
The absolute increase in value over the period. Growth = final value minus initial value.
predator growth rate (dP/dt)
The absolute increase in value over the period. Growth = final value minus initial value.
prey equilibrium N* = γ/δ
Sample size or count used in the calculation.
predator equilibrium P* = α/β
The value at the specified point or condition.
Lotka-Volterra model
The most frequently occurring value.
current population trend
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
