“…For the state of São Paulo, 15 species were reported and nine new records for the Parque Estadual das Fontes do Ipiranga were recently registered by Ferreira & Bicudo (2017) Kützing and S. tenera W.Gregory. The ecological studies about Surirellales for tropical and subtropical regions are still very scarce and address pH preferences, trophic state, and physical and chemical water parameters (e.g. Cocquyt et al, 2014;Cocquyt & Taylor, 2015;Cocquyt et al, 2017).…”

Aim The aim of this study was to inventory the diatom species of order Surirellales present in the surface sediments of tropical reservoirs (São Paulo State, Brazil) and to correlate their distribution with environmental (pH, total phosphorus, and total nitrogen) and spatial predictors. Methods Samplings were carried out in 31 reservoirs from 2009 to 2014. Vertical profile of water samples was collected in the summer and winter along the reservoirs, and their water column mean results were used to characterize each sampling site. We measured water transparency, euphotic zone, water depth, pH, dissolved oxygen, total nitrogen, and total phosphorus. Surface sediment samples (2 cm top) were collected for diatom analyses. A partial RDA was performed between species abundance data (response matrix) and environmental and spatial variables (predictor matrices). Results 14 species of Surirellales were identified from the surface sediment samples, five of them being identified only at the genus level. Overall, partial RDA showed that the species distribution is constrained by both environmental and spatial predictors. Species were mainly ordinated in relation to pH and light availability. Conclusion Our results demonstrated that the Surirellales species revealed ecological preferences to low nutrient concentrations, neutral to slightly acidic waters, and higher light availability. Moreover, our results suggest that both environmental and spatial factors are important for their species distribution.

Tropical reservoirs are sensitive to eutrophication but long-term impacts of impoundment on their productivity and biota are poorly understood. Here, we employ a palaeolimnological approach to assess whether ecological baselines can be defined for reservoirs, and examine the challenges and management implications. We studied the environmental history of five reservoirs in Brazil with different productivities, using sediment records covering the period since reservoir construction (* 50-90 years). Our main goals, based on the analysis of organic geochemistry (TOC, TN, TP, C:N), stable isotopes Electronic supplementary material The online version of this article (

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 estudo. Cinco espécies foram identificadas: E. proboscidea Kützing, E. gibba (Ehrenberg) Kützing, E. gibberula (Ehrenberg) Kützing, E. operculata (C. Agardh) Ruck & Nakov e Epithemia sp., com dominância de espécies perifíticas. Um táxon foi registrado pela primeira vez para o Brasil (E. proboscidea Kützing) e dois táxons para a área do PEFI (E. gibba (Ehrenberg) Kützing e E. operculata (C. Agardh) Ruck & Nakov).
