Tests with starved larvae showed that the ammonia tolerance of starved larvae of S. Tests in varying ionic composition of the water illustrated that the absence of sodium ions accounts for a considerable increase in ammonia toxicity.

An analysis of the time-budget and a description of reproductive behaviour at a small pond in Vicosa, Minas Gerais, Brazil are presented.
