Provedor de dados: 103
Autores: Senna,André R.; Mugnai,Riccardo; Reddy,Yenumula Ranga.
A new amphipod species of Bogidiellidae Hertzog, 1936 is described and illustrated based on specimens collected from bore wells in the state of Andhra Pradesh, Southern India. The new species is closely related to those belonging to a group of Bogidiella species with inner rami of pleopods reduced or absent. Bogidiella totakura sp. nov. differs from all the other species in the group mainly by the shape, size and ornamentation on gnathopods and telson. This is the second Indian species of Bogidiella.

Multimetric index for assessing ecological condition of running waters in the upper reaches of the Piabanha-Paquequer-Preto Basin, Rio de Janeiro, Brazil
Provedor de dados: 103

The objective of this study was to develop a rapid multimetric index using benthic macrofauna as bioindicators of ecological conditions for the upper reaches of the Piabanha-Paquequer-Preto Basin located in the state of Rio de Janeiro, Brazil. A total of 33698 macroinvertebrates were collected in 27 sites. Benthic macroinvertebrates were sampled using the multi-habitat method that consists in sampling 20 m² of substrate collected in approximate proportion to the representation of all major habitat types in the reach. A subsampling procedure was used. The main steps followed to develop and test the index were: exclusion of unsuitable metrics using box-whisker plots, considering the degree of overlapping among interquartile limits (1º-3º) and confirmed by...

A predictive multimetric index based on macroinvetebrates for Atlantic Forest wadeable streams assessment

Abstract: Multimetric Indices (MMIs) have been widely applied for ecological assessment in freshwater ecosystems. Most MMIs face difficulties when scaling up from small spatial scales because larger scales usually encompass great environmental variability. Covariance of anthropogenic pressures with natural environmental gradients can be a confounding factor in assessing biologic responses to anthropogenic pressures. This study presents the development and validation of a predictive multimetric index to assess the ecological condition of Atlantic Forest wadeable streams using benthic macroinvertebrates. To do so, we sampled 158 sites for the index development. We adjusted each biological metric to natural variation through multiple regression analyses...
