1. Criptógamos do Parque Estadual das Fontes do Ipiranga, São Paulo, SP. Algae, 44: Bacillariophyceae (Surirellales: Epithemia)
RESUMO Foi realizado um levantamento florístico de Epithemia (Bacillariophyceae) na área do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP, Brasil, com o objetivo de conhecer a diversidade taxonômica e a variabilidade morfológica do gênero. Ao total, 31 lâminas de diatomáceas foram examinadas das quais cinco foram usadas no presente est

2. Changes in the taxonomic structure of periphytic algae on a free-floating macrophyte (Utricularia foliosa L.) in relation to macrophyte richness over seasons
ABSTRACT Periphyton has a strong relationship with aquatic macrophytes, which are key components of spatial heterogeneity in the littoral zone. We evaluated the relationship between the community structure of periphytic algae on Utricularia foliosa and macrophyte richness and coverage and limnological variables in a shallow reservoir. Water sampling for phys

3. Use of food resources and resource partitioning among five syntopic species of Hypostomus (Teleostei: Loricariidae) in an Atlantic Forest river in southern Brazil
ABSTRACT We analyzed the diet and resource partitioning among five syntopic species of Hypostomus Lacépède, 1803 in the Corumbataí River in southeastern Brazil. The gut contents of 352 individuals were assessed and 21 food items were identified and quantified under an optical microscope. The food items found in the gut contents indicate that these suckerm

5. Structure and dynamics of the community of periphytic algae in a subtropical reservoir (state of São Paulo, Brazil)
Much remains to be learned about biological diversity, which constitutes a valuable natural resource. Due to the pressure that human activity has put on natural resources, biodiversity has been reduced, often unbeknownst to those responsible for that activity. Therefore, we aimed to perform a quantitative and qualitative analysis of periphytic algae in the I

6. Algas perifíticas como indicadoras de qualidade em ambientes impactados pela drenagem ácida de minas na região carbonífera de Santa Catarina
A Drenagem ácida de minas (DAM), do ponto de vista ecológico, influencia os ambientes aquáticos provocando condições de stress para a maioria dos organismos. O baixo valor de pH (geralmente <3,0), altas quantidades de sulfatos e íons metálicos dissolvidos diminuem a diversidade biológica. Esses locais podem ser caracterizados como ecossistemas simple

7. Respostas ecofisiológicas da comunidade perifítica in situ a diferentes condições ambientais no Rio Santa Maria da Vitória, ES
The physiological ecology responses of periphyton in the high course of the Santa Maria da Vitória (ES) river had been evaluated during one year, in two stations. The determined environmental variables had been: temperature, transparency, euphotic zone, depth, pH, OD, electric conductivity, STD, NO2 -, NO3 -, total-N, PO4 - and total-P. The Periphyton in na
