From: Comparison and analysis of two forms of harvesting functions in the two-prey and one-predator model
The sketch map of the two forms of harvesting functions. (a) A harvested predator–prey model with traditional form of harvesting function. (b) A harvested predator–prey model with a new form of harvesting function, where \(\phi_{1}\) and \(\phi_{2}\) denote the predator response function of two prey species, respectively. \(\eta _{1}\) and \(\eta_{2}\) are the rate of conversion of prey. \(g_{1}\) and \(g_{2}\) are the growth pattern of two prey species. m is the per capita death rate of predator
