“…Thus the overall diversity (41) of the area here studied can be considered generally lower than that recorded in warmer tropical/subtropical regions of the country. However, this difference is valid only for the streams analyzed (Assis et al 2004, Anjos-Santos & Costa 2006. The richness registered in the lentic sites of the middle Jacuí River was sometimes higher (De Marco Junior & Latini 1998, De Marco Junior et al 1999, Franco & Takeda 2002, Fonseca et al 2004, Fulan & Henry 2006, 2007, and sometimes lower (Ferreira-Peruquetti & Fonseca-Gessner 2003, Juen et al 2007 than that recorded in other natural and artificial standing waters in the country.…”

“…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.…”

Diversity of Odonata (Insecta) larvae in streams and farm ponds of a montane region in southern Brazil

et al. 2013

View full text Add to dashboard Cite

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.

“…Progomphus is mainly found in lotic environments, presents burrowing habit adapted to dig and burrow in streams' sandy beds (Assis et al, 2004;Costa et al, 2004;Ramírez, 2010). On the other hand, Tramea and Erythrodiplax occur in lentic habitats and have sprawling habit, wherein the first colonizes sediments mainly composed of clay, sand and stones, whereas the second preferably dwells densely vegetated sites (Carvalho & Nessimian, 1998;Costa et al, 2004;Figueiredo et al, 2013).…”

“…In turn, immature individuals are longitudinally distributed along water bodies according to their ecological requirements (Assis et al, 2004;Remsburg & Turner, 2009) in search of food, oxygenated water and refuge (Corbet, 1980). These organisms are important functional components of aquatic ecosystems, with essential role in the food chain because they are predators at all life stages (Corbet, 1999;Carchini et al, 2007) and are preyed upon by fish, amphibians and reptiles (Souza & Costa, 2006).…”

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...

“…The content of this and the granulometric composition of the sediment exert great influence on aquatic biodiversity (Súarez et al, 2001;Takeda & Fujita, 2004;Príncipe & Del Corigliano, 2006) for differences in both complexity and environmental heterogeneity among lakes (Pressinatte Junior et al, 2016). The organic matter is important for its great contribution in the diet of most aquatic organisms (Darnell, 1964;Alongi, 1998), which acts as a determinant factor on the species composition and allows the occurrence of different communities among the floodplain lakes (Barreto, 1999;Assis et al, 2004;Townsend et al, 2010).…”

Abstract: Aim: Identify the effects of sediment composition and water conditions on diversity, richness, evenness, density and composition of freshwater Oligochaeta in shallow floodplain lakes. Methods: We sampled 13 shallow floodplain lakes quarterly during the year 2010 in the Upper Paraná River floodplain. In each lake, four sediment samples were taken from the shore and central regions, three of them were used for biological analysis, and one for granulometric analysis. Concomitantly, temperature, dissolved oxygen, pH, conductivity, alkalinity, turbidity and chlorophyll-a were also measured. Initially, the biological samples were analyzed by a stereoscopic microscope. Oligochaeta individuals were identified under optical microscope at the lowest possible taxonomic level. For data analysis, we quantified density, richness, evenness and diversity index of freshwater Oligochaeta. In order to show differences between the months and the analyzed lakes, in relation to the percentages of coarse and fine organic material, the nonparametric Kruskal Wallis test was used. We also calculated the sediment granulometric diversity using the Shannon-Wienner index, using a simple regression analysis. We correlated assemblage attributes of Oligochaeta with sediment diversity and the assemblage species with the limnological variables using the Spearman correlation. Results: A total of 2,090 individuals were found distributed among 27 species. From the total individuals number, 57% were Pristina americana, followed by Dero (Dero) righii with 13%. Assemblage attributes were not significantly correlated with sediment diversity, and 7 of the 27 species recorded showed significant correlations with at least some of the abiotic variables. Conclusions: We verified that the abiotic variables of the water present greater influence on the attributes of the assemblage of freshwater Oligochaeta, when compared with sediment influences. Although we found low local diversity of this group, the wide range of water conditions offered by lakes culminates with a great species richness considering the whole landscape.
