“…Arguing against the spatial heterogeneity justification, they refer to a simple two-patch model (Abrams, 1994) and to spatial models (Barraquand, 2014;Abrams, 2015) that ignore directed movements of predators, and thus cannot demonstrate the emergence of predator-or ratio-dependence at the population level. Predator-prey models with prey-taxis show that the active movements of predators generate spatially heterogeneous dynamics, stabilizing trophic systems at both local and landscape scales (Sapoukhina et al, 2003;Tyutyunov et al, 2019). Emerging population clustering induces predator interference at the population level.…”

“…Thus, this implied mechanism is evolutionary advantageous strategy, which allows prey and predator to coexist safely and avoid the collapse of total overgrazing, and therefore increases the efficiency of the whole system. The effect of increased viability of trophic system due to the active predator's movements was earlier revealed for spatial prey-predator models with the indirect (inertial) prey-taxis [22,23,27,30].…”

“…In the model presented here (hereinafter referred to as TZA model), predator's migrations are explicitly formalized as indirect (or equivalently, inertial) prey-taxis stimulated by the degree of starvation, which leads to the Patlak-Keller-Segel flux of the predator population density [8,11]. As shown in [22][23][24][25][26][27][28][29], in the frameworks of the taxis-diffusion-reaction systems this approach enables us to account for the inertial delay in the consumer's response to varying distribution of the prey. Recently, another model of the same biological system has been presented in [7] (hereinafter referred to as SA model).…”
