“…For instance, the ten species were recorded every year and remained the most abundant; also no significant species replacement occurred during the sampling years. This apparent stability in the face of harsh environmental variation has already been reported in many systems (Ross et al 1985;Matthews et al 1988;Meffe and Berra 1988;Hued et al 2010). Several factors may contribute to the persistence and stability of fish assemblage in the transitional zone.…”

“…All metrics employed in this study indicated that fish assemblage structure was relatively stable in the study area. Comparing with the index in other reports (e.g., Meffe and Minckley 1987;Meffe and Berra 1988), which were above 0.9, indicating high persistence in their fish assemblages, the index of persistence (equaled to 0.68) in our study was moderate, indicating that the species composition of our study area was relatively constant. Both lentic and lotic species may co-exist in the transitional zone, using the habitat simultaneously, thus this zone may have a high number of rare species (Oliveira et al 2003) and result in the moderate persistence index.…”

The construction of dams may lead to dramatic changes in fish assemblages due to the loss of lotic habitat caused by impoundment, which have been well documented. However, knowledge of the temporal variation of fish assemblages in the transitional zone, which is an ecotone between lotic and lentic environments of the reservoir, is still very rare. In the present study, fishes in the transitional zone of the Three Gorges Reservoir were sampled from 1997 to 2002 and from 2006 to 2009 to investigate interannual variations of fish assemblages. The results showed that 9 families, composed of 77 species, were found in the transitional zone with Cyprinidae as the dominant group. By cluster analysis (CLUSTER) and non-metric multidimensional scaling analysis (MDS), assemblages were separated into two groups at a Bray-Curtis similarity value of 77.26%, representing the pre-impoundment period and post-impoundment period. Following analysis of similarity percentages of species contributions (SIMPER), shifts in abundances of Coreius guichenoti, Rhinogobio cylindricus and Coreius heterodon, etc. contributed most to the difference between the two groups. Surprisingly, contrasting to the drastic changes in lacustrine region, the fish assemblage in the transitional zone appeared to be relatively stable, since the ten core species caught were consistently recorded every year, and no significant species replacement occurred during our study period. Besides, the moderate index of persistence indicated persistence of the fish assemblage as well, in spite of the shift of some species. Based on the results of ordination and time-lag analysis, the fish assemblage in the transitional zone showed no directional change. We conclude that fish assemblage in the transitional zone of the Three Gorges Reservoir was stable across the surveyed years. Based on our results, we propose that maintenance of dynamic transitional zones in reservoirs will be useful for the preservation of fishes, particularly for the endemic species inhabiting the upper Yangtze.

“…A hypothesized consequence of this variation is the prevention of competitive exclusion through its negative effect on population size (Grossman et al, 1990). Some authors suggest that some populations of stream fish assemblages could vary substantially (Grossman et al, 1990), whereas others show stability and persistence (Matthews, 1986;Matthews et al, 1988;Meffe and Berra, 1988), and these discrepancies have caused some ecological debate (Grossman et al, 1982;Yant et al, 1984). In brazilian streams, Mazzoni and Lobón-Cerviá (2000) observed some spatio-temporal persistence of the ichthyofauna in an isolated coastal stream, without lateral and longitudinal migration neither periodical pulsed floods.…”

Riffle and pool fish communities in a large stream of southeastern Brazil

The structure of the fish communities of a pool and a rapid in the ribeirão Santa Bárbara is described. This stream of 5 th order is a direct tributary of the rio Tietê in the system of the upper rio Paraná. Thirty three species, from nine families and three orders, were referred in the two mesohabitats: the pool with 31 species, and the rapid with 18. Orders Characiformes, Siluriformes, and Perciformes presented the greatest number of species in the two mesohabitats. The families Characidae and Loricariidae were the most specious, followed by Cichlidae in the pool, and by Parodontidae in the rapid. Most species were accidental, 17 in the pool, and 10 in the rapid, and only six were constant in the two mesohabitats. The greatest diversity and evenness occurred in the pool. The seasonal variation for both assemblages was high, with the pool having a high turnover of species that could be due to the proximity with main channel of the rio Tietê.A estrutura das comunidades de peixes de um poço e uma corredeira do ribeirão Santa Bárbara é descrita. Esse é um ribeirão de quinta ordem, afluente direto do rio Tietê no sistema do Alto rio Paraná. Trinta e três espécies, de nove famílias e três ordens, foram capturadas nos dois meso-hábitats: 31 no poço e 18 na corredeira. Characiformes, Siluriformes e Perciformes apresentaram o maior número de espécies nos dois meso-hábitats. As famílias Characidae e Loricariidae foram as mais ricas em espécies, seguidas por Cichlidae, no poço, e por Parodontidae, na corredeira. A maioria das espécies foi acidental, 17 no poço e dez na corredeira; somente seis espécies foram constantes nos dois meso-hábitats. As maiores diversidade e uniformidade ocorreram no poço. A variação sazonal no poço e na corredeira foi alta, com o poço apresentando uma grande substituição de espécies, que pode ser devida à proximidade com o canal principal do rio Tietê.

“…The trophic composition of these assemblages is persistent over time (MeFFe & berra, 1988) and is composed of fish which occupy almost the entire spectrum of trophic niches which occur in aquatic communities (wineMiller et al, 2008). Insectivores dominate headwater courses (Paller, 1994), whereas omnivores tend to increase with stream order (sMiley Jr et al, 2005;wineMiller et al, 2008;ibañez et al, 2009).…”

ABSTRACT. The aim of this study was to test whether the richness observed and the biomass per trophic group of fish assemblages vary depending on the order (1 st and 2 nd ) of the streams located in three different basins of the Upper Paraná River Basin, Central Brazil. Samples were collected between April and September, 2009, in 27 streams of the Meia Ponte, Piracanjuba and Santa Maria River basins. A total of 4,879 specimens were collected distributed in 59 species and 19 families. The statistical analyses carried out indicate that the observed richness and biomass of omnivore fish were influenced by the interaction of two factors: stream order and basin. The 2 nd order streams located in the Santa Maria basin presented significant differences in the observed richness and omnivore biomass when compared to i) 1 st order streams in the same basin (only richness) or in the Piracanjuba and Meia Ponte basin; ii) 2 nd order streams in the Piracanjuba (only omnivore biomass) and Meia Ponte Rivers basins. Results are discussed considering the influence of geomorphic processes on fish assemblages and food availability. KEYWORDS.Trophic guilds, omnivores, richness, biomass.RESUMO. Avaliação das assembleias de peixes de riachos de diferentes ordens na bacia do alto rio Paraná, Brasil Central. O objetivo deste estudo foi testar se a riqueza observada e a biomassa por grupo trófico das assembleias de peixes variam de acordo com a ordem (1ª e 2ª) dos riachos localizados em três bacias diferentes do sistema do alto rio Paraná, Brasil Central. As amostras foram coletadas entre abril e setembro de 2009 em 27 riachos das bacias dos rios Meia Ponte, Piracanjuba e Santa Maria. Um total de 4.879 espécimes foi coletado distribuídos em 59 espécies e 19 famílias. As análises estatísticas realizadas indicam que a riqueza observada e a biomassa de peixes onívoros foram influenciadas pela interação de dois fatores: a ordem do riacho e a bacia. Os riachos de 2ª ordem localizados na bacia do rio Santa Maria apresentaram diferenças significativas de riqueza observada e biomassa de onívoros, quando comparado: i) aos riachos de 1ª ordem da mesma bacia (somente a riqueza), da bacia do rio Piracanjuba ou do Meia Ponte; ii) aos riachos de 2ª ordem da bacia do rio Piracanjuba (somente a biomassa de omnívoros) ou do rio Meia Ponte. Os resultados obtidos são discutidos considerando a influência dos processos geomórficos sobre a assembleia de peixes e a disponibilidade de alimento.
