After 3 d, the seeds were recovered from the softened fruit by sieving.
Grain-size analyses were carried out by dry sieving 2-3 kg of pyroclastic samples.
The clay is refined by sieving it, and the extracted material is reinjected into the clay body.
The inclusions result from coarser sieving when preparing the paste, keeping the coarse nonplastics as temper (instead of throwing them away).
The liquid, consisting of water and effluent, was collected in a tray at the bottom of the sieving device.
The sand fraction (63-2000 m) was determined by wet sieving, with silt (2-63 m) and clay (<2 m) determined by hydrometer.
All remaining material after sieving was collected in a fabric-mesh sieve (0.3-0.5 mm opening diameter).
The molluscan infauna of dead wood was also included, but no sieving for soil infauna was attempted.
