摘要

Periphyton is essential for the functioning of aquatic ecosystems, contributing mainly to primary productivity and acting at the base of the food web. Temperature is a determining factor in the development of periphytic algae, as it influences community structuring and colonization process. In this context, the primary production of periphyton was evaluated on artificial substrates (glass slides) for 60 days in temperature treatments at 28, 30 and 32 ºC. The experiment occurred in mesocosms located in a fish-farming tank. The biomass proxy of the periphyton was evaluated through Chlorophyll a, and the environmental variables were verified. To investigate the effect of temperature and colonization time on periphytic biomass, repeated-measures ANOVA was applied. The highest biomass peak was recorded in the treatment at 32 ºC, specifically 20 days after the start of the experiment. In contrast, the lowest amount was observed at 32 days in the treatment at 30 ºC. We concluded that the highest temperature of 32 ºC determined greater biomass of periphytic algae and more accelerated colonization process.
