“…Using suitable transformations to reduce the number of parameters in predator-prey models and susceptible-infective-removed models has been widely used in other works. 4,5,16,19,21,[34][35][36][37] Recall that (x, ) ∈ R 2 is an equilibrium of (4) if it satisfies f (x, y) = 0 and g(x, ) = 0. An equilibrium point (x, y) is said to be positive if x, y ≥ 0 and to be a positive interior equilibrium if x, y > 0.…”

“…One of the classical predator‐prey models is the Lotka‐Volterra predator‐prey model often used to describe the dynamics of biological systems in which two species interact. Since 1925, a variety of predator‐prey models have been proposed by introducing functional responses such as Holling‐Tanner predator responses, Beddington‐DeAngelis functional responses, ratio‐dependent functional responses, and harvesting rates . The dynamical behaviors of these models have been widely investigated and analyzed.…”

“…Mathematical modeling in harvesting of species was started by Clark [1,2]. There are mainly three types of harvesting according to Gupta et al [3]: (i) ℎ( ) = ℎ, constant rate harvesting (see [4][5][6][7]), (ii) ℎ( ) = , proportionate harvesting (see [8,9]), and (iii) ℎ( ) = /( 1 + 2 ) (Holling type II), nonlinear harvesting (see [10][11][12][13]). Nonlinear harvesting is more realistic and exhibits saturation effects with respect to both the stock abundance and the effort level.…”
