Popis:	Daytime variations in temperature, dissolved oxygen concentration and pH were investigated at 3-hourly intervals from 6a.m. to 6 p.m. January had the lowest temperature values, while at noon; September and January had the lowest air and pond water temperature values respectively.Dissolved oxygen increase from 6a.m., to 6p.m., with peak values during the 3p.m. readings. ANOVA showed no significant difference in pH values at the various times of the day (p≥ 0.05), while the t-test showed no significant difference in a seasonal pH values (p ≥0.05). Keywords: Daytime, temperature, D0, pH, Ponds AJAZEB Vol. 6 2004: pp. 71-75
