Key differences, features, and comparative analysis of Concept and Formula.
| Concept | Formula |
|---|---|
| Density change | Nt+1 = Nt + [(B + I) − (D + E)] |
| Intrinsic rate of natural increase | r = b − d |
| Exponential growth (differential) | dN/dt = (b − d)N = rN |
| Exponential growth (integral) | Nt = N0 ert, e = 2.71828 |
| Logistic growth | dN/dt = rN [(K − N)/K] |
| Doubling time (exponential) | t = ln 2 / r = 0.693 / r |
| Fastest logistic growth | at N = K/2 |
