A second x = 0 isocline
exists at x=0 and thus lies on the vertical axis.
Optimal foraging and the form of predator isocline
to construct the outlines of the morphologic elements in parallel plans and to define the isocline
q] = 0 isocline
is always defined at m'(k*) = [rho] + [omega] + [theta].
analyses, target neighbor experiments, and foraging observations in Montana and Nebraska prairies, using adult generalist and specialist grasshoppers, have successfully identified feeding-based mechanisms of interspecific competition, including the included niche, on a number of occasions (Belovsky 1986, Chase and Belovsky 1994, Chase 1996).
Equation--The equation specifying the least-cost combination of a set of input factors for production of any specified quantity of output.
biomass at a given density in a species mixture is not different from that predicted by the linear isocline
for growth in pure stands [[[Alpha].
The steady state of (P) is a local saddlepoint if and only if the slope of the [Mathematical Expression Omitted] isocline
is greater than the slope of the [Mathematical Expression Omitted] isocline
, evaluated at the steady state.
t]) corresponding to equation  is in fact the [DELTA]H = 0 isocline
in H - X space.
t] = E = isocline

2] axis: as x increases, isodine 1 moves down while isocline
2 moves up (Fig.
The previous assumption of grazer emigration being independent of producer biomass yields a grazer isocline
parallel to the producer axis.
