Effect of Social Behavior Amongst Predator-Prey Populations

Procedure:

 

 

User Instructions:

 

The simulator consists of three regions, Input variables menu, Simulation control buttons and Result display window.
 

 

Input Variables Menu:

 

 

Using this drop-down menu control, the user can select either spatial distribution or cooperation among predators.

 

 

Under spatial distribution, by using the second drop down menu, the user can select either rate at which new individuals are added to the population or effect of different theta values.

 

 

Under cooperation among predators, by using the second drop down menu, the user can choose either cooperation among predators or equilibrium densities and population stabilities.

 

 

Spatial distribution -> Rate at which new individuals are added to the population.

 

 

The user can change set of variables including Rate of growth, Carrying capacity, Encounters result in kill, Predator conversion, predator death rate and Theta. The zero population growth rate of predator will plot a vertical line in spatial distribution graph, which indicates that the number of birth is equal to the number of death.

Spatial distribution -> Effect of different theta values.

 

 

The user can change set of variables including initial prey population, initial predator population, rate of growth, carrying capacity, number of steps, step size, encounters result in kill, predator conversion, predator death rate. Theta is a slider bar by which user can set his desired value and re-run the iteration. There are two options provided for plotting the graph is, Predator density vs. Prey density and Time vs. population density. The user can choose either of them and observe his results on the graph.

Cooperation among predators -> cooperation among predators.

 

 

The user is allowed to enter the appropriate value for the initial predator population and also to set his desired value for the advantage of the predator, which is set as slider bar in the simulator.

Cooperation among predators -> equilibrium densities and population stabilities.

 

 

The user is allowed to set the parameters, initial prey population, initial predator population, rate of growth, carrying capacity, number of steps, step size, predator conversion, predator death rate and theta. The user can change the parameter 'Advantage to predator' and set his desired value and can re-run the iterations.

 

Simulation Control Buttons:

 

 

These set of buttons are used for controlling the simulation.

 

Result Display Window:

 

 

Showing the graphical representation for the tab 'rate at which new individuals are added to the population', x-axis: carrying capacity and y-axis: the prey population.
