“…Such a refined classification reflects both the riverscape concept (Fausch et al, 2002) and the river wave concept (Humphries et al, 2014), both of which reflect the pulsed nature of river-lake ecosystems, even in systems as large as the Laurentian Great Lakes (Regier et al, 2013).…”

“…Due to the usual high biomass and diversity of fishes, large rivers in the Neotropical region provide a good opportunity to understand processes related to secondary production (Roach, 2013;Humphries et al, 2014). Many conceptual models such as the River Continuum Concept (Vannote et al, 1980), the Flood Pulse Concept (Junk et al, 1989), and the Riverine Productivity Model (Thorp, Delong, 2002), were developed to explain variations in primary and secondary production over space and time.…”

Empirical studies have supported contrasting hypotheses to explain the most important factors influencing the sources of basal production that support secondary production, including: hydrologic regime, turbidity, concentrations of dissolved organic matter, lateral connectivity between the river channel and floodplain, and amount of floodplain vegetation (see Roach, 2013 andHumphries et al, 2014 for a review).…”

Diet and trophic structure of the fish assemblage in the mid-course of the Teles Pires River, Tapajós River basin, Brazil

This study was carried out in a section of the middle course of the Teles Pires River, a clear water river that drains ancient and highly eroded geological formations, and where five hydropower plants are planned or in construction. In this study we tested the hypothesis that local fish fauna is mainly sustained by autochthonous food resources, with modest changes in the trophic structure of fish assemblages along the hydrometric cycle. Sampling was performed every three months between July 2008 and May 2009 at seven sites distributed along a 50-km section of the river. Piscivores was the most representative group in terms of biomass, abundance and species richness, followed by herbivores, insectivores and omnivores. The trophic structure did not change significantly during the hydrometric cycle, only omnivores showed significant temporal variation in abundance. The main food resources consumed by the ichthyofauna were of autochthonous origin, mainly immature aquatic insects and fish. Eight of 34 species showed temporal variations of the food resources consumed. Our results corroborate the hypothesis that the fish fauna of large, clear water rivers can be sustained by autochthonous resources. This contributes to understanding some determinants of fish production in large Neotropical rivers. Este estudo foi desenvolvido em um trecho do curso médio do rio Teles Pires, um rio de águas claras que drena regiões de terreno geologicamente antigos, e onde cinco usinas hidrelétricas estão previstas ou em construção. Dado a transparência da água e as características do terreno nos hipotetizamos que a fauna de peixes local é principalmente sustentada por recurso autóctone e com alterações pouco significativas na estrutura trófica ao longo de um ciclo hidrométrico. As amostragens foram realizadas trimestralmente entre julho/2008 e maio/2009 em sete pontos dispostos ao longo de um trecho de cerca de 50 km do rio. Piscívoros foram os mais representativos em biomassa, número de exemplares e riqueza de espécies, seguidos pelos herbívoros, insetívoros e onívoros. Não houve mudança significativa na estrutura trófica da assembleia ao longo do ciclo hidrométrico, apenas onívoros apresentaram significativa variação temporal na abundância. Os principais recursos alimentares utilizados pela ictiofauna foram de origem autóctone, sobretudo insetos imaturos e peixes. Oito de 34 espécies apresentaram variação temporal na dieta. Os resultados corroboram a hipótese de que grandes rios de água clara podem ser sustentados majoritariamente por recursos autóctone. Desta forma, este estudo contribui para a compreensão de alguns fatores determinantes da produção secundária em grandes rios Neotropicais.

“…Since 1980, several models have been developed that have greatly improved our understanding of how dynamic river ecosystems function, and which continue to contribute to current river science research. Five such models are the River Continuum Concept (RCC) [54], the Serial Discontinuity Concept (SDC) [55], the Flood Pulse Concept (FPC) [5], the Riverine Productivity Model (RPM) [56], and the River Wave Concept [57].…”

Within the context of fluvial systems, geospatial modeling of river networks consists of describing certain patterns in the geographical or geomorphological "fabric" along the course of rivers or streams and correlating these patterns to physical, ecological, biological and chemical processes in the river/stream system's aquatic environment. Patterns may consist of different sets of similar sequences of geomorphological characteristics, sediment substrate type or flow velocity fields. These patterns will influence processes by defining, for example, behaviors in river ice formation or breakup (physical), fish habitat types (ecological) and transformations in water-quality constituents (biological and chemical). In this special issue of Geospatial Modeling of River Systems, we invited papers to present models and data that correlate geographic/geomorphic features of a river or stream system with physical/ecological/biological/chemical processes in the lotic aquatic environment.
