The figure shows the loci and depicts the nonnegative orthant where the isoclines
in equations and compose four isosectors labeled (i) - (iv).
Mean spring salinities at each deployment site showed the same relative longitudinal gradient during all years, but variations in freshwater inflow conditions caused locations of salinity isoclines
to shift in both up- and downstream directions (Table 3).
Equations (20) to (22) can be solved to yield two k = 0 isoclines
and a single [dot.
The correspondings to this period, isoclines
are shown in the figure 3.
Referring to the Texas MAP isoclines
(Larkin & Bomar, 1983:18),
For fixed x, the isoclines
are linear; x determines where the isoclines
intersect the [u.
No solution exists for n [greater than or equal to] 5, because the corresponding isoclines
never meet [ILLUSTRATION FOR FIGURES 2A,B OMITTED].
We have not attempted a formal local-stability analysis of the discrete-grazer model, but the plots of producer productivity and producer isoclines
The slopes of the isoclines
are given in the last equation of the proof.
The null isoclines
give the threshold of zero growth for each of the two species, and their intersection specifies the equilibrium point.
However, due to the relative position of these isoclines
1], The zero growth isocline
is augmented by isoclines
