Carrying Capacity Calculator
Estimate K from Two Population Points
Estimate carrying capacity from population at two time points
Resource-Based Carrying Capacity
Estimate K from available resources and per-individual requirements
Formula
Resource-based K = Total resources / Resources per individual. From logistic model: K can be estimated by fitting Nt = K/(1 + ((K−N₀)/N₀)×e^(−rt)) to observed data.
Frequently Asked Questions
What is carrying capacity?
Carrying capacity (K) is the maximum population size an environment can sustain indefinitely given available resources like food, water, habitat, and other necessities.
What factors affect carrying capacity?
Carrying capacity depends on abiotic factors (temperature, water, space) and biotic factors (food availability, predation, disease, competition). It can change over time as conditions change.
What happens when a population exceeds K?
When a population exceeds carrying capacity, density-dependent factors like starvation, disease, and competition increase, causing the population to decline back toward K (sometimes oscillating).
