“…However, it is still necessary to test family-level in a biomonitoring program for streams in the whole region, considering there is substantial difference of biota among the biomes. Finally, few studies in Latin America have dealt with developing and testing of other important aspects of biomonitoring protocols, such as sampling procedures and mesh sizes (Buss and Borges 2008), sample size (Schneck and Melo 2010), subsampling methods (Oliveira et al 2011a;Ligeiro et al 2013a), and taxonomic sufficiency (e.g., Melo 2005;Buss and Vitorino 2010).…”

Water quality agencies and scientists are increasingly adopting standardized sampling methodologies because of the challenges associated with interpreting data derived from dissimilar protocols. Here, we compare 13 protocols for monitoring streams from different regions and countries around the globe. Despite the spatially diverse range of countries assessed, many aspects of bioassessment structure and protocols were similar, thereby providing evidence of key characteristics that might be incorporated in a global sampling methodology. Similarities were found regarding sampler type, mesh size, sampling period, subsampling methods, and taxonomic resolution. Consistent field and laboratory methods are essential for merging data sets collected by multiple institutions to enable large-scale comparisons. We discuss the similarities and differences among protocols and present current trends and future recommendations for monitoring programs, especially for regions where large-scale protocols do not yet exist. We summarize the current state in one of these regions, Latin America, and comment on the possible development path for these techniques in this region. We conclude that several aspects of stream biomonitoring need additional performance evaluation (accuracy, precision, discriminatory power, relative costs), particularly when comparing targeted habitat (only the commonest habitat type) versus site-wide sampling (multiple habitat types), appropriate levels of sampling and processing effort, and standardized indicators to resolve dissimilarities among biomonitoring methods. Global issues such as climate change are creating an environment where there is an increasing need to have universally consistent data collection, processing and storage to enable large-scale trend analysis. Biomonitoring programs following standardized methods could aid international data sharing and interpretation.

“…Others also have demonstrated that fixed-count size can affect richness estimates (e.g., McCord et al, 2007;Oliveira et al, 2011), the separation between sites or groups (e.g., Cao et al, 2002a;Schneck and Melo, 2010), and performance of MMIs (e.g., Doberstein et al, 2000) and O/E indices (e.g., Nichols et al, 2006;Ostermiller and Hawkins, 2004).…”

“…All samples were then combined into a single composite sample and preserved with 80% ethanol. In the laboratory, we adopted the subsampling procedure (as tested by Oliveira et al, 2010), which consisted in homogenising the sample on a gridded tray and taking randomly 6 of the 24 quadrats. These six subsamples were fully examined and macroinvertebrates were removed, counted and identified at the lower taxonomic level possible, which was genus-level for all groups but Diptera, Hemiptera and Lepidoptera, which were identified to familylevel.…”

The influence of connectivity in forest patches, and riparian vegetation width on stream macroinvertebrate fauna

We assessed two dimensions of stream connectivity: longitudinal (between forest patches along the stream) and lateral (riparian vegetation), using macroinvertebrate assemblages as bioindicators. Sites representing different land-uses were sampled in a lowland basin that holds a mosaic of protected areas. Land-use analysis, forest successional stages and riparian zone widths were calculated by the GIS analysis. Macroinvertebrate fauna was strongly affected by land-use. We observed a continuous decrease in the number of sensitive species, %Shredders and IBE-IOC biotic index from the upstream protected area to highly deforested sites, increasing again where the stream crosses a Biological Reserve. When analysing buffer strips, we found aquatic fauna responding to land-use alterations beyond the 30 m riparian corridor (60 m and 100 m wide). We discussed the longitudinal connectivity between forest patches and the riparian vegetation buffer strips necessary to hold high macroinvertebrate diversity. We recommend actions for the increase/ maintenance of biodiversity in this and other lowland basins.Keywords: bioassessment, biomonitoring, aquatic insects, riparian zone, conservation.Influência da conectividade dos fragmentos florestais e da largura da vegetação ripária sobre a fauna de macroinvertebrados em um ecossistema lótico ResumoNeste trabalho, foram avaliadas duas dimensões de conectividade em um ecossistema lótico: longitudinal (entre fragmentos florestais ao longo do córrego) e lateral (mata ripária), utilizando-se assembléias de macroinvertebrados como indicadores. Pontos que representam diferentes tipos de usos da terra foram amostrados em uma bacia de planície litorânea, que abriga um mosaico de áreas protegidas. As análises de uso da terra, os estágios de sucessão florestal e as diferentes larguras da zona ripária foram calculados utilizando-se um SIG. A fauna de macroinvertebrados foi fortemente afetada pelo uso da terra. Partindo-se da área protegida à montante, observou-se um decréscimo contínuo do número de espécies sensíveis, da porcentagem de fragmentadores e do índice biótico IBE-IOC até o trecho fortemente desflorestado, no médio curso do rio; os valores aumentam novamente, quando o rio atravessa uma Reserva Biológica. Ao analisar a largura da vegetação ripária, constatou-se que a fauna aquática responde às alterações além do corredor ripário com 30 m de largura (60 m e 100 m de largura). Discutiu-se sobre a conectividade longitudinal entre fragmentos florestais e sobre a largura necessária da vegetação ripária para manter a alta diversidade de macroinvertebrados. Dessa forma, foram feitas recomendações visando a favorecer o aumento/a manutenção da biodiversidade, tanto na bacia analisada como em outras bacias localizadas em planícies litorâneas.Palavras-chave: bioavaliação, biomonitoramento, insetos aquáticos, zona ripária, conservação.
