Tambaqui (Colossoma macropomum) is the most important native freshwater fish farmed in Brazil. Production and supply chains are consistently growing, while current yearly production levels of this species exceed 200.000mt. Recent efforts of our research team have produced a draft genome sequence for this species. Here we describe results from SNP discovery efforts using deep sequencing of reduced representation libraries (RRLs) of varying fragment sizes. Ten micrograms of bulked DNA samples from 63 unrelated fish (males and females) were completely digested with HaeIII. |

The Pantanal is an important active sedimentary basin in central South America where highly diverse flora and fauna are sustained by seasonal floods. Intense land use in the catchment areas enhanced sediment load and destabilized avulsive river systems in the plains. A well-known avulsion in the Taquari River during the 1980-90s, called 'Zé da Costa', has shifted the river mouth and drastically changed the nearby landscapes, making them difficult to map because of the hard access and the large variations in spectral and spatial attributes of raster data like Landsat images. Therefore, we developed a useful method to map and explore landscape changes in 'Zé da Costa' avulsion that combines geotagged field pictures, randomly selected high-resolution orbital truths, normalized difference vegetation index, digital elevation models, linear spectral mixture models and Landsat historical imagery in pixel-based and object-oriented supervised classifications. We found that bands in green, red, and near-infrared spectra provide better mapping results with object-oriented algorithms for deriving and studying temporal dry/wet ratio dynamics. The temporal analyses of the dry/wet ratio showed that avulsions in the Taquari River have the potential to change permanently the 'Zé da Costa' area into a dry landscape, making it susceptible for land use (deforestation and fire), except areas seasonally inundated by the floods of the Paraguay River. Overall, our method might be also useful for long-term studies of land use and climate change in avulsive rivers in wetlands around the world.
