  • 摘要:Delamere Lake is a small (< 2 ha), shallow (mean depth 1.7 m), acidic (pH 4.5) lake amid coniferous forest in Cheshire, England. It showed high total nutrient concentrations (200 ± SEM 14 μg L -1 total phosphorus, 2.2 ± 0.1 mg L -1 total nitrogen), very high phytoplankton biomass (290 ± 30 μg L -1 chlorophyll a), and monospecific green algal dominance (Dictyosphaerium pulchellum, maximum biovolume 33.8 mm 3 L -1 , < 99% of total phytoplankton biovolume). Zooplankton was dominated by rotifers (mainly Keratella quadrata and Brachionus urceolaris), with a few cladoceran species (Alona guttata, Chydorus sphaericus, and Scapholeberis mucronum). Abundant Chaoborus flavicans larvae were the top predators in this fishless lake.
