Figure 9 Result of CCA analysis on the amphipod abundances and water characteristics. TN: total nitrogen, TP: total phosphorus, TB: total number of bacteria, TVB: total number of viable bacteria. Other symbols mean pools surveyed in each season by "month-pool number": for example, 5-CH1 corresponds to CH1 pool surveyed in May.
