The following gadget of distinction equations represents two species x and y competing for a frequent useful resource (Leslie 1959; Piclou, 1977). Note that will increase in the populace dimension of x or y limit the populace dimension for the different species. (a1 + 1)x *1 = 1 + xy + through 21, b > zero (az + 1)y, You 1 + b2x, + y az, h2> zero (a) There are threc cquilibria of the shape (0,0), (x", 0), (0, y*). Find x* and y*: (b) Determine prerequisites on the parameters so that the equilibria in phase (a) are regionally asymptotically stable. (c) There is a fourth equilibrium (1,ỹ). Find prerequisites on the parameters so that i and j are positive. (d) Assume az/b2 > a, and a 1/6, > az. What can you say about the balance of the equilibrium (,)? If one of the incqualities is reversed, what can you say about the balance of (, y)?
