Increasing hydropower expansion in hyper-diverse tropical river basins is currently threatening aquatic biodiversity on an unprecedented scale. Among the largest and most controversial of these projects is the Belo Monte Hydroelectric Complex being constructed on the Xingu River, a major Amazon tributary in Brazil. Despite the potentially large impacts, almost no baseline ecological data are available for the river’s diverse ichthyofauna. This study uses ecomorphology and stable isotope…

Evidence of migratory behaviour for large catfish within the Xingu River is shown, emphasizing the influence of the hydrologic cycle on their movements.
Body shape separates guilds of rheophilic herbivores (Myleinae: Serrasalmidae) better than feeding morphology
- Environmental ScienceProceedings of the Academy of Natural Sciences of Philadelphia
- 2019
Under a phylogenetic framework, micro-computed tomography scanning is used to compare functional feeding traits among 26 species of serrasalmids and compared body shape between pacus using geometric morphometrics to identify potential locomotor adaptations for rheophily, suggesting body shape has more important ties to diet.

New metrics derived from stable isotope data are applied to provide quantitative measures of trophic diversity within populations or species to test the hypothesis that sympatric invaders belonging to the same functional feeding group occupy a smaller isotopic niche than their allopatric counterparts.

The analysis supports the thesis that species interactions are important determinants of community morphological features, particularly in species-rich tropical regions and interprets evidence of greater niche diversification at lower latitudes within a habitat type as being derived primarily from the influence of competition and predation.

Stable isotope-based Bayesian community-wide metrics are used to investigate patterns in trophic structure in five estuaries that differ in size, sediment yield and catchment vegetation cover in Mozambique and Kenya and the Rianila, and there was seasonality in troPHic structure at Ambila and Betsiboka, as Trophic diversity increased and trophi redundancy decreased from the prewet to the postwet season.
