Fig. 18.5 Simulation output of the mean biomass of the food web along an elevation gradient
during seasonal variations in water level in the last year (year 10). Starting from day 50 (a) each 60
days a 'snapshot' was made until the end of the simulation (f). The water level amplitude during
this simulation run was 0.6 m
of the wet-dry water margin, these cascading effects become more complex and
may be difficult to distinguish from the pulses of invading or retreating popula-
tions. In Fig.

, for example, the invertebrates show a double peak around the
wet-dry water margin. The invertebrate's peak observed on the right side is the
