✦ Synopsis

The distribution of phytoplankton was studied in Lake Lanao, Philippines. In calm weather, the species segregate vertically with motile species and buoyancy-regulating species above other species in the water column. On a distance scale of 12.5 km, horizontal variability yields a coefficient of variation of 23.60/, for total biomass, 30.20/0 for net primary production, and an average of 30.3?'0 for individual species biomass after removal of error variances. Variabilities on a scale of 1 km are about half as large. Horizontal patchiness of individual species is not related to their abundance, surface t o volume ratio, morphotype, or taxon, but is negatively related to their size.
