1. Despite the importance of Llangorse Lake as the largest natural body of fresh water in South Wales, no long-term limnological project has ever been planned for the lake. 2. A mass of data is available from sampling carried out at intervals since 1

Observations of the degree of branching in various populations of Stigeoclonium tenue Kutz. were correlated with physical and chemical parameters of the environment. Water velocity and depth did not affect the degree of branching, whereas the latter

The phycoperiphyton on Perspex slides is investigated after an exposure for four weeks at six stations in the upper course of the River Wye System from June 1979 to June 1981. The pigment contents were between 0.1 and 48 mg/m2 chlotophyll-a as well a

The Bacillariophyta dominated over the other phyla and were mainly recorded in high densities during summer and autumn. The Chlorophyta and Myxophyta (Cyanobacteria) were represented by coccoid forms and by non-heterocystous, filamentous forms, respe

Studies were made to investigate the minimum time that should be allowed for settling of fixed, freshwater phytoplankton prior to enumeration. Results using a 16 cm vertical column at 20°C indicated that to obtain complete sedimentation the sample s

Seasonal studies of nuclear phases in clonal and naturally occurring plants of Lemanea fluviatilis L. in the River Usk have shown that N = 18–19 and 2N = 36–38. Carposporophytes, carpospores, the Chantransia-stage and lower cells of gametophyte t

The distribution and frequency of Stigeoclonium tenue Kutz. in some South Wales rivers were studied for 12 months to assess the value of the alga as an indicator of organic pollution. It colonised organically polluted areas at most times of the year,
