Kylla M. Benes and Robert C. Carpenter. 2015. Kelp canopy facilitates understory algal assemblage via competitive release during early stages of secondary succession. Ecology 96:241–251. http://dx.doi.org/10.1890/14-0076.1

Appendix E. Percent cover of each understory algal species observed at the beginning and end of the canopy manipulation experiment.

Table E1. The percent cover of species of foliose red algae and brown algae 40 days and 505 days after the disturbance with the canopy present and with the canopy removed.  Data are shown by type of disturbance treatment (NR, no removal; UR, upright; CR, complete removal).  The percent cover of articulated coralline algae and crustose coralline algae also are shown for comparison.  A dash is used when a species was not found in a particular plot type during that sampling period.
