"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Raw data of species presence/absence and quadrat attributes

R dump file containing raw data, y1: species presence (1) / absence (0) for each quadrat in 1992, y2: species presence (1) /absence (0) for each quadrat in 2014, plot: quadrat attributes (position: 0 for lower slope, 1 for upper slope, slope: slope angles (degree), affect: 0 for not gaps, 1 for gaps created or affected by the mass mortality). Vectors adj, weights and num are spatial data for OpenBUGS.
