Full description

Species composition trends for the microheterotrophic grazing community (<300 um) over an annual period (1998-1999) were determined for the upper Swan River estuary. Also differences in grazing rates, monthly over an annual cycle and changes in grazing pressure and grazer species composition over the course of a typical (summer dinophyte) bloom were measured.

Statement: Annual species composition trends for the microheterotroph community were determined from monthly surface and bottom water samples which were collected from the study site at Ron Courtney Island (February 1998 to January 1999) as described in Chapter 3 of the thesis during noon and night-time sampling trips using a positive displacemnet pump. Whole water samples collected the following day at noon for the grazing experiments were also analysed for species composition. During the summer Dinophyte seasonal bloom study (January 1996) weekly whole water samples were collected from three depts (0.25 m, 2.5 m and 4.5 m) over a four week period using a purpose-built 6-litre horizontal water sampler, designed to collect from a narrow (15 cm) depth range. Changes in grazer species composition and diurnal depth-related distribution patterns were established for the course of the bloom.
