Figure 2

Filtration rate (FR) and biodeposition (BD) of Unio douglasiae at different densities (0.5, 1.0, and 2.0 individulas·L^-1) in (a) river water (RW) and (b) lake water (LW). FR and BD of mussels at (c) six concentrations of chlorophyll-a and with (d) eight different algal species as prey. SEL: Selenastrum gracile (KCTC-AG10009); CHL: Chlorella vulgare (UTEX-265); ABW: algal bloom water; OSC: Oscillatoria sancta (NIER-10019); NTP: Nitzschia palea (NIES-489); NTM: nontoxic Microcystis aeruginosa (NIES-101); ANA: Anabaena flos-aquae (NIER-30010); TM: toxic Microcystis aeruginosa (NIES-298).
