“…Members of Acanthagrion, for example, are abundant in lentic and lotic environments (Ferreira-Peruquetti & De Marco Junior 2002, Franco & Takeda 2002, Assis et al 2004, and Oxyagrion may dominate in lakes and on floodplains (Fulan & Henry 2006, Juen et al 2007. Erythrodiplax also predominated in ponds and wetlands of central and southernmost Brazil (De Marco Junior et al 1999, Maltchik et al 2010. Dominance of Lestes in ponds was also reported for Argentinean grasslands (Ellenrieder 2009).…”

“…Besides, the occurrence of odonates has been documented in less than one-third of the Brazilian territory, and especially in areas with tropical and subtropical climates (De Marco Junior & Vianna 2005). Additionally, bioecological studies have focused mainly on lakes and floodplains (De Marco Junior & Latini 1998, Franco & Takeda 2002, Fulan & Henry 2006, 2007, Juen et al 2007, Giacomini & De Marco Junior 2008, while main channels of lowland rivers (Ferreira-Peruquetti & De Marco Junior 2002, Assis et al 2004), montane streams (Dalzochio et al 2011), wetlands (Maltchik et al 2010), reservoir and fishfarms (De Marco Junior et al 1999, Fonseca et al 2004) are poorly known.…”

“…Inventories of adult individuals (Costa 1971, Teixeira 1971) and larvae from wetland systems (Maltchik et al 2010) constitute the only references for the order, and inventories in lotic environments are missing. The occurrence of small reservoirs along streams is too common, and must contribute to the establishment of a typical fauna of lentic environments, along the stream banks.…”

This study presents an inventory of the genera of Odonata found in streams and artificial farm ponds in a montane region, with temperate climate, in southern Brazil. Differences in richness of lotic and lentic environments were also investigated. The diversity of odonate families and genera in southernmost Brazil is lower than in warmer, either tropical or subtropical, regions of the country. Nine genera are new records for the region and six genera had their geographical ranges extended to regions with temperate climate of the Neotropics. The overall richness and especially the overall abundance recorded in the studied area are possibly determined by the occurrence of numerous farm ponds because natural standing waters are scarce in the region. The presence of macrophytes in these artificial ponds allowed the establishment of a diversified odonatofauna, typical of lentic environments. Resumo: Este estudo apresenta um inventário de gêneros de Odonata de riachos e reservatórios artificiais de uma região montanhosa de clima temperado no extremo sul do Brasil. Diferenças na riqueza de ambientes lóticos e lênticos também foram investigadas. A diversidade de famílias e gêneros de Odonata no extremo sul do Brasil é menor que em regiões mais quentes, tanto tropicais quanto subtropicais, do país. Nove gêneros são novos registros para a região e seis gêneros tiveram suas distribuições geográficas de ocorrência estendidas para áreas temperadas da região Neotropical. A riqueza e a abundância verificadas na área de estudo possivelmente foram determinadas pela ocorrência de numerosos reservatórios artificiais, pois áreas lênticas naturais são raras na região. A presença de macrófitas nestes reservatórios permitiu o estabelecimento de uma fauna de Odonata diversificada e típica de ambientes lênticos. Palavras-chave: libélulas, inventário, região Neotropical, reservatórios, fauna lótica.

“…Several studies have shown the wide distribution of immature Odonata in streams where the composition and distribution of these insects are influenced by the interaction among physical, chemical, structural and hydrological variables (Gibbs et al, 2004;Maltchik et al, 2010;Raio et al, 2011;Che Salmah et al, 2012;Gómez-Anaya et al, 2013). Thereby, changes in the water body characteristics can strongly influence the spatial and temporal distribution patterns of the odonatofauna (Buss et al, 2002(Buss et al, , 2004Silveira et al, 2007).…”

ABSTRACT. This study investigated the assemblages attributes (composition, abundance, richness, diversity and evenness) and the most representative genera of Odonata, Anisoptera at Água Boa and Perobão Streams, Iguatemi River basin, Brazil. Both are first order streams with similar length that are impacted by riparian forest removal and silting. Quarterly samplings were conducted from March to December 2008 in the upper, intermediate and lower stretch of each stream. The Mantel test was used to check the influence of spatial autocorrelation on the Odonata composition. Spatial variations in the composition were summarized by the Principal Coordinates Analysis (PCoA) using Mantel test residuals. The effects of spatial correlation on richness and abundance were investigated by the spatial correlogram of Moranʼs I coefficients. The most representative genera in each stream were identified by the Indicator Value Method. The spatial variations in the attributes of the assemblages were assessed using analysis of variance of null models. We collected 500 immature individuals of 23 genera and three families. Among the attributes analyzed only the composition and abundance showed significant spatial differences, with the highest mean abundance found in the Perobão Stream. Miathyria and Zenithoptera were the indicator genera of the Água Boa Stream and Erythrodiplax, Libellula, Macrothemis, Progomphus and Tramea were the indicator genera of the Perobão Stream.

Assembleia de imaturos de Odonata (Insecta, Anisoptera) em riachos sul-matogrossenses: implicações espaciais. Este trabalho investigou atributos de assembleias (composição, abundância, riqueza, diversidade e equitabilidade) e os gêneros mais representativos de Odonata, Anisoptera nos riachos Água Boa e Perobão, bacia do rio Iguatemi, MS, Brasil. Os riachos são de primeira ordem, apresentam extensão similar e são impactados pela remoção da mata ripária e assoreamento. As amostragens foram realizadas trimestralmente de março a dezembro/2008 nos trechos superior, intermediário e inferior de ambos os riachos. O teste de Mantel foi utilizado para verificar a influência da autocorrelação espacial sobre a composição de Odonata. Variações espaciais na composição foram sumarizadas através da Análise de Coordenadas Principais (PCoA) utilizando-se os resíduos do teste de Mantel. Os efeitos da correlação espacial na riqueza e abundância foram investigados através do correlograma espacial dos coeficientes do I de Moran. Para identificar os gêneros mais representativos em cada riacho foi utilizado o Método do Valor Indicador. As variações espaciais dos atributos das assembleias foram avaliadas por meio de análises de variância de modelos nulos. Foram coletados 500 indivíduos imaturos distribuídos em 23 gêneros e três famílias. Dentre os atributos analisados, apenas a composição e abundância apresentaram diferenças espaciais significativas, sendo o maior valor médio do último atributo regi...
