Özet

1. Whitemere, a kettle-hole lake in north-west England (z(m),14 m, area 22.5 ha) has extremely high maximal concentrations (around 1 mg L-1) of total phosphorus (TP) and soluble reactive phosphorus (SRP), and comparatively low maximal concentrations of dissolved inorganic nitrogen (<0.5 mg N L-1). Bioassays indicate that its phytoplankton, is nitrogen limited, and it has surface blue-green algal blooms in summer. Palaeoecological investigations have shown that high populations of cyanophytes occurred more than 6000 years ago, even before human settlement of the catchment.
