Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil
Provedor de dados: 49
Autores: Braun,Bruna Marmitt; Salvarrey,Andrea Vanesa Batalla; Kotzian,Carla Bender; Spies,Marcia Regina; Pires,Mateus Marques.
The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages’ genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages’ distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The...

Diversity of Odonata (Insecta) in Seasonal Deciduous Forest fragments in southern Brazil (state of Rio Grande do Sul), with a new record for the state and comments on the seasonal distribution of the species
Provedor de dados: 49

Abstract: We present an Odonata (Insecta) check list of species occurring in a fragment of the Seasonal Deciduous Forest (Atlantic Forest biome) from the central region of the state of Rio Grande do Sul (RS), southern Brazil, along with a list of the odonate species recorded in this phytoecological region for the state. In addition, we provide comments on the seasonal distribution of the species occurring in the study area. Two streams and seven farm ponds located in the middle course of the Jacuí River basin were surveyed between December 2007 and February 2009. Overall, we recorded 49 species from 21 genera and six families. Argia serva Hagen in Selys, 1865 (Coenagrionidade) had its first occurrence record mentioned for the state, elevating to 183 the...

Diversity of Odonata (Insecta) larvae in streams and farm ponds of a montane region in southern Brazil
Provedor de dados: 49
Autores: Pires,Mateus Marques; Kotzian,Carla Bender; Spies,Marcia Regina; Neri,Damaris Battistel.
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...

Suficiência amostral para estudos de impacto ambiental sobre a comunidade de macroinvertebrados bentônicos em arrozais irrigados
Provedor de dados: 65

RESUMO: O objetivo deste estudo foi determinar a suficiência amostral para estudos de impacto ambiental sobre a comunidade de macroinvertebrados bentônicos em arrozais irrigados (Oryza sativa L.). Amostragens de solo foram realizadas com auxílio de coletor cilíndrico, nos anos agrícolas 2007/08 e 2012/13. As amostras foram triadas e os espécimes identificados até o nível de família. Os dados foram submetidos à análise da curva do coletor e os índices de diversidade de Shannon e equabilidade de Pielou foram calculados para o total de amostras e o número de amostras definido pela curva do coletor, em cada ano amostral. Considerando o método de amostragem verificado no presente trabalho, indica-se um mínimo de 12 réplicas para se obter o maior número de...
