By (7) and the Implicit Function Theorem, the [Mathematical Expression Omitted]
isocline does not shift, since [Mathematical Expression Omitted], while the [Mathematical Expression Omitted]
isocline shifts up because [Mathematical Expression Omitted].
The
isocline and full system analyses show similar patterns when there is variation in performance (Figs.
If so, the grazer
isocline will shift upward and to the left (compare grazer
isoclines in Fig.
We derived the following equation for the zero-growth
isocline, equivalent to the self-thinning line, for a sampling area of 36 [cm.
The dynamics of the grazer-algae system are directly determined by the shape and relationship of the
isoclines shown in Fig.
In the absence of resource exchange, the equilibrium point is where per-year consumption meets acquisition and is represented by the intersection of the isolation acquisition
isocline and the consumption vector (points 1 in [ILLUSTRATION FOR FIGURE 1A, B OMITTED]).
A simple way to visualize the growth response of a plant to the levels of two environmental factors is by plotting its zero
isocline in the resource plane [ILLUSTRATION FOR FIGURE 1 OMITTED].
The shape of a gerbil
isocline measured using principles of optimal habitat selection.
3B, we have depicted the plant
isocline (given by dP/dt = 0) and the herbivore
isoclines (given by dH/dt = 0) in the plant-herbivore plane.
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).
The correspondings to this period,
isoclines are shown in the figure 3.
Referring to the Texas MAP
isoclines (Larkin & Bomar, 1983:18),
