individuals start at 5 mg, and curves are shown for three different starting positions.

D. Consequences of Adding Abiotic Movement
The consequences of simulated turbulence (abiotic movement) on size spec-
tra and life-history parameters are quite trivial with average values differing
from the control by less than 5% in all cases (
Table 3
). However, the variance
of the metrics (slope, intercept, etc.) did increase with increased variability in
