Table 1.
Experimental design testing how the frequency of disturbance (one or three disturbance events) over a three month period influenced recruitment and community dynamics, when the net severity of disturbance was the same (one disturbance of 100% compared to three disturbances of 33%).
Frequency of disturbance | Timing control | Net-Severity | Month #1 | Month #2 | Month #3 |
---|---|---|---|---|---|
Triple | 50% | 17% | 17% | 17% | |
100% | 33% | 33% | 33% | ||
Single | #1 | 50% | 50% | ||
100% | 100% | ||||
#2 | 50% | 50% | |||
100% | 100% | ||||
#3 | 50% | 50% | |||
100% | 100% |
Additionally, this was crossed with two different net severities of disturbance (50% or 100%, kelp canopy removal). To account for potential differences due to the timing of disturbance, we implemented timing controls whereby in each month (#1, #2 or #3) a new treatment plot was disturbed once. N = 40, 5 replicates for each treatment. Each row of this table represents one of the eight treatments deployed in the experiment.
