             abstract = "The diversity and distribution of freshwater insects in South 
                         America is poorly known. Riffle beetles (Elmidae) are aquatic 
                         Coleoptera that are considered important indicators of 
                         environmental integrity. In Brazil, the country with the largest 
                         area and highest richness of Elmidae in the Neotropics, the 
                         diversity of the family remains incipient. The southern region of 
                         Brazil (state of Rio Grande do Sul) reportedly has a higher 
                         richness of stream insects than other regions. In this study, we 
                         used species distribution models (SDMs) to estimate the potential 
                         distribution of riffle beetle taxa in southern Brazil to identify 
                         areas with elevated diversity and suggest priority areas for 
                         further investigation towards conservation of Elmidae. As most 
                         records of Elmidae were represented by larvae, we predicted the 
                         potential distribution firstly of genera and secondly of species 
                         within the genus Macrelmis because they were available as adults 
                         and allowed identification to species level. These were modelled 
                         in relation to environmental factors such as climate, topography, 
                         hydrography and land cover. Our results suggested that montane 
                         regions and basins located within well-preserved forested regions 
                         indicated the highest potential richness of Elmidae. In addition, 
                         the areas with higher predicted suitability for the occurrence of 
                         genera overlapped with the suitable areas for species of 
                         Macrelmis. This result suggests the existence of an elevated 
                         ecological similarity among most of the modelled taxa, and that 
                         projections for certain Elmidae genera can be useful proxies for 
                         estimations of the potential distribution of species in the 
                         region. The most important environmental factors related to the 
                         predicted distribution of Elmidae taxa were associated with 
                         climate (precipitation), landscape (forest cover) and topography. 
                         Unsurprisingly, freshwater ecoregions were also suggested as 
                         important drivers of Elmidae distribution. Our results indicate 
                         that conservation efforts for aquatic insects such as riffle 
                         beetles in Brazil should focus on watersheds located in montane 
                         and forested regions.",
