Darren W. Johnson. 2006. Predation, habitat complexity, and variation in density-dependent mortality of temperate reef fishes. Ecology 87:1179–1188.

Appendix A (Table A1). Analysis of covariance (ANCOVA) of the effects of habitat complexity (i.e., refuge-based density) on proportional loss from isolated units of habitat.  Two levels of habitat complexity (no. fish per unit kelp) were analyzed with initial number of fish (per unit water volume) as a covariate.
