We can understand these equations much better by using the state space, a
special kind of graph. In the state-space graph, the x axis represents the
abundance of species 1, and the y axis represents the abundance of species 2.
This graph ...
An increase in N1 in the state space is represented as a horizontal arrow pointing
to the right. The arrow is horizontal because the abundance of species 1 is
represented on the x axis. When you work with state-space graphs, pay close ...
In this region of the state space graph, the predator population declines,
represented by downward-pointing vertical arrows. To the right of the isocline,
there is an excess supply of victims, and the predator population increases,
represented by ...
