In ZeBook: Working with Dynamic Models for Agriculture and Environment

Description

Predator-Prey Lotka-Volterra model (with logistic prey)

Usage

predator.prey.model(grH = 1, kH = 10, mrH = 0.2, eff = 0.5,
  mrA = 0.2, H0 = 1, A0 = 2, duration = 200, dt = 1,
  method = "euler")

Arguments

grH	: relative rate of prey population growth
kH	: environment carrying capacity for prey (number per ha)
mrH	: maximum predation rate (number per predator and per prey per day)
eff	: efficiency, growth of predator population depending on predation (-)
mrA	: mortality of predator (-)
H0	: size of population of prey, at time 0
A0	: size of population of predator, at time 0
duration	: simulation duration
dt	: time step for integration
method	: integration method

Value

data.frame with daily H and A
