Nessa E. O'Connor, Jonathan H. Grabowski, Laura M. Ladwig, and John F. Bruno. 2008. Simulated predator extinctions: predator identity affects survival and recruitment of oysters. Ecology 89:428–438.

Appendix C (Table C1). Results from ANOVA testing effects of removing different combinations of species of predator with and without compensation for the loss of biomass on (a) juvenile oyster survival (ArcSin transformed), (b) oyster recruitment (square-root transformed), and (c) percentage organic matter (square-root transformed). n = 5. Nested factors are displayed in brackets.
