Results

           Different test species were impacted in various ways by S. terebinthifolius.All treatments with S. terebinthifolius had a significant negative impact on the survival of the isopod S. quadridentata, relative to the control, but there were no significant differences among the S. terebinthifolius treatments (Figure 1A). The green porcelain crab Petrolisthes armatus was not significantly affected either by density or the condition of the S. terebinthifolius fruits (Figure 1B). For the eastern mud snail I. obsoleta, only the treatment with 10 crushed fruits had significantly reduced survival relative to the control and all other treatments (Figure 1C).

           The first trial with the brine shrimp, A. salina, found no significant differences among treatments with 5 intact fruits, 5 crushed fruits, and 10 intact fruits (Figure 2). However, survival in these treatments was all significantly reduced relative to the control. The treatment with 10 crushed fruits significantly reduced survival relative to all other treatments. The second brine shrimp trial found no significant differences among treatments (Figure 2). Finally, in the third brine shrimp trial, survival was only significantly reduced by the treatment of 10 crushed fruits (Figure 2).
