Table 2. Propensity to drift/strand based on drift intensity respectively stranding density to benthic density of the most common taxa across all HP reaches (‘ALL’) and separated by reach. Larger numbers (mean ± standard error) suggest higher propensity to drift/strand (the three largest numbers of each reach and for ‘ALL’ are indicated in bold). Asterisks indicate taxa with relative abundances > 1% in the drift/stranding but not in the benthic samples (Appendix C in Data S1).
