Table 1.
Hypothesized and observed (in parentheses) responses of competition metrics in concurrent and sequential treatments. Predictions included: H = high, M = moderate, L = low. We hypothesized mixed concurrent treatments would exhibit lower virulence and parasite success, and higher replication (evidence of within host competition) relative to single treatments. We hypothesized sequential treatments would exhibit evidence of prior resident advantage and be similar to corresponding single treatments.
