# 2-species competition

## Explanation

This model represents the competitive interactions between two species as a two dimensional autonomous ordinary differential equation (shown in the applet).
The main ingredientes of this applet are:

- The populations of each species: coded as
*x*and*y.* - The nullclines: marked in
**blue**(for species x) and**red**(for species y). - The trajectories in the phase space: represented by
**green**lines (two different trajectories are represented here).

- The
**green**points are the initial conditions of this trajectories - The
*r*coefficients control the speed of the dynamics - The competition coefficients are coded in the array
*K.*They have an straightforward geometrical meaning as the intersection points between nullclines. Thus, the values of*K*can be modified dragging and dropping the highlighted points in the nullclines
