“…Mayflies (Insecta: Ephemeroptera) are an important component of aquatic systems, as they are abundant in all types of environments, play an important role in nutrient cycling and reflect changes in water quality (McCafferty, 1983;Rosenberg and Resh, 1993). The sensitivity of Ephemeroptera to physical, chemical and physical-chemical changes of an aquatic system has been well described in the literature (e.g., Brittain, 1982;Salles et al, 2004;Domı´nguez et al, 2006). Therefore, Ephemeroptera is regarded as a useful research subject in studies with different ecological approaches (e.g., Francischetti et al, 2004;Goulart and Callisto, 2005;Buss and Salles, 2007;Siegloch et al, 2008;Shimano et al, 2010;Souza et al, 2010).…”

-Community diversity is expected to reflect variations in local conditions but, recently, ecologists have started to realize that local diversity is also under pressure from global processes. As a result, the traditional view of community structure based on local interspecific interactions was replaced by the idea that community structure is a result of multiple processes acting in different spatial scales. This study is aimed at quantifying the relative importance of spatial, environmental and spatially structured processes on Ephemeroptera community in Cerrado streams in Brazil. Thirty-four rivers and streams in the Brazilian state Mato Grosso were sampled. Ephemeroptera species composition, based on abundance and presence data, was evaluated in relation to niche and neutral predictors by using a partial redundancy analysis (pRDA). Results obtained through the pRDA indicated that both environmental and spatial processes influenced Ephemeroptera abundance. On the other hand, only environmental processes showed effects on community patterns when using species presence data from preserved, altered and large streams and also when looking only at the preserved sites. When streams larger than 20 m were excluded from analysis, both environmental and spatially processes showed influence on Ephemeroptera composition. Adjusted R 2 values were higher for environmental than for spatial processes in all analyses. The relatively high influence of both environmental processes and stream width in the analyses highlights the sensitivity of mayflies assemblies to environmental variation, and emphasizes the importance of local processes, as predicted by niche theory, while neutral processes act to a lesser extent on the structure of the studied communities.

“…Com base na publicação da Lista das espécies de Ephemeroptera registradas para o Brasil (Salles et al 2004), a qual vem sendo atualizada freqüentemente pela internet no sítio Ephemeroptera do Brasil (http://sites.google.com/site/ephemeropterabr/home), o Espírito Santo foi considerado um dos estados brasileiros menos estudados com relação ao grupo no país, encontrando-se numa situação comparável apenas aos estados da Região Nordeste bem como à maioria da Região Norte. Até 2008, apenas 12 espécies haviam sido registradas para o Espírito Santo, sendo praticamente metade dessas baseadas em apenas uma coleta na Reserva Santa Lúcia, município de Santa Teresa ).…”

Despite the fact that the state is one of the smallest in Brazil, representing only 0.53% of the country area, a surprising diversity was found. Seventy-six species, 41 genera and nine families were identified, which represents about 25% of the species reported from Brazil, 65% of the genera, and almost all families. Of these, 17 species (most of Baetidae and Leptophlebiidae) are new to science. Five species, collected only at the nymphal stage, could not be identified to the species level. The present work demonstrates that, as for other organisms, the diversity of mayflies is high in the state, and more works aiming to investigate the aquatic insect composition of the Espírito Santo State should be encouraged.

“…Taxonomic identification of nymphs was performed based on papers containing original descriptions and redescriptions, books and thesis (e.g. Domínguez & Flowers 1989, Domínguez et al 1994, 2006, Domínguez 1999, Salles et al 2004, Salles 2006.…”

The first studies of Leptophlebiidae in the Santa Catarina State, Southern Brazil, dated from 1920. Since then, not much is known about the family (even to the Order Ephemeroptera) to the State. The main goal of this study was to survey fauna of Leptophlebiidae in the Santa Catarina State based on nymphs. The material was obtained from the collection deposited at the Laboratório de Pesquisa em Ecologia e Química of the Universidade Comunitária da Região de Chapecó, besides additional specimens collected between 2008 and 2009. Occurrences were plotted in the hydrograph map of Santa Catarina State, with one map for each genus. The Leptophlebiidae nymphs were recorded in 26 aquatic environments that included small streams and rivers. We identified 24 morphotypes distributed in 12 genera. Number of genera in the Western of Santa Catarina increased from eight to 15. Thraulodes, Ulmeritoides and Homothraulus presented higher frequency of occurrence in the region. Leentvaaria and Hermanella were associated to regions well conserved such as in the Araucaria forest. Needhamella and Segesta were related mainly to Irani River.
