title: FLOATING COMMUNITIES OF ALGAE IN AN ARTIFICIAL POND IN THE PARQUE DO ESTADO, SÃO PAULO, BRAZIL(1).
abstract: A fresluvater floating algal community was repeatedly observed in an artificial pond in the Parque do Estado São Paulo, Brazil. The ontogeny and composition of the community are discussed and are related to oxygen liberation during photosynthesis of the periphyton, or of the pond-bottom algne, which carries up portions of the algae growing there.
