Vinegaroons are members of a guild apex arthropod predators in the high desert grasslands southeastern Arizona. Despite their importance as major ecosystem, almost nothing is known about potential prey, predators, or competitors. We evaluated predator-prey relationships vinegaroons and 30 species 27 detailed interactions among three taxa predator guild. With few exceptions, overpowered preyed o...

In this paper, a mathematical model for the system of prey-predator with immigrant prey has been analyzed to find an approximate solution population density, local and predator density. Furthermore, we present novel soft computing technique named LeNN-WOA-NM algorithm solving prey. The proposed uses function approximating ability Legendre polynomials based on neural networks (LeNNs), global sea...

In this paper we study the global dynamics of 3–dimensional predator prey Lotka–Volterra systems, which describes two predators competing for food or shared one resource. From theoretical analysis on all parameters of this system, we show that if the resource for prey is limited, then there exist some values of parameters such that two predators and one prey coexist and their population are asy...

Analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth. We aimed to formalize the conditions in which spatial biological control can be achieved by generalists, through an analytical approach based on reaction-diffusion equations. Using c...
