Biomonitoring in Brazil

Bob Hughes has consulted on 3 projects in Brazil since 2003. The research occurred in the 3 major ecoregions of that country: Atlantic Forest, Cerrado (savanna), and Amazon Forest.

In multiyear studies of the nonwadeable Rio Paraiba do Sul and its tributaries, together with wadeable streams draining to Guanabara Bay, he has worked with a senior professor and 2 Ph.D. and 1 M.Sc. students at the Federal Rural University of Rio de Janeiro and the Federal University of Rio de Janeiro. The major outputs of this research are Ph.D. and M.Sc. degrees by the students and 6 journal publications (Oliveira et al. 2011; Pinto et al. 2006, 2009; Terra et al. 2013a, 2013b, In Press).. Dr. Hughes’ contributions to this research included advising on survey design, sampling methodologies, data analyses, and manuscript preparation.

In a multi-university study of 40 stream sites and the receiving reservoir in each of 4 Cerrado river basins, Bob Hughes has worked with 3 professors and 9 graduate students from the Federal University of Minas Gerais, Federal University of Lavras, and Pontifical Catholic University of Minas Gerais since 2007. To date, this research has resulted in 5 Ph.D. and 4 M.Sc. degrees, 1 book (Callisto et al. 2014), and 14 journal publications (Castro et al. 2013a, 2013b; Ferreira et al. 2014, 2015; Ligeiro et al. 2013a, 2013b; Macedo et al. 2012, 2014; Martins et al. 2015; Molozzi et al. 2011; Sanches et al. In Press; Silva et al. 2014; Tupinambás et al. In Press). Several additional manuscripts involving basic macroinvertebrate and fish assemblage ecology and the use of those assemblages in assessing anthropogenic impacts on streams and reservoirs are in preparation. Dr. Hughes’ contributions to this research included advising on survey design, sampling methodologies, data analyses, and manuscript preparation, as well as field sampling.

In a multi-university multi-disciplinary study of 40 stream sites in each of 2 Amazon River sub-basins, Bob Hughes has worked with 5 professors and 9 graduate students from the Federal University of Lavras, Federal University of Amazonas, Federal University of Para, and University of Cambridge since 2010. To date 2 manuscripts have been published (Gardner et al. 2013; Oliveira et al. In Press). Additional papers involving basic macroinvertebrate and fish assemblage biogeography and the use of those assemblages in assessing anthropogenic impacts on streams are in preparation. Dr. Hughes’ contributions to this research included advising on survey design, sampling methodologies, data analyses, and manuscript preparation, as well as field sampling.
