“…Invertivorous species composed the dominant guild of this assemblage. This result is in agreement with the ones already obtained for other tropical (Angermeier and Karr 1983;Bojsen and Barriga 2002;Silva 1993;Uieda et al 1997;Deus and Petrere-Junior 2003;Pouilly et al 2006;Ibanez et al 2007) and temperate forested streams (Schlosser 1982;Rahel and Hubert 1991;Oberdorff et al 1993Oberdorff et al , 2002 suggesting a possible convergence in trophic structure between temperate and tropical fish assemblages ). Trophic diversity of fish assemblages in such systems may be strongly related to food availability (Angermeier and Karr 1983), which in turn may be influenced by common environmental constraints.…”

-We explored the relationships between diet and morphology in 30 fish species from forested tropical streams of the Bolivian Amazon. These species were first assigned to eight broad trophic guilds based on stomach contents analysis. The relationships between diet and morphology were then examined using Redundancy Analysis, after having checked for potential phylogenetical effects. Results show that, independently of any phylogenetic constraints, some of the trophic guilds could be grossly predicted from few relevant morphological attributes (i.e. relative intestinal length, standard length and mouth orientation) and thus suggest a significant link between diet and morphology. In other words, species having similar diet tend to converge to some extent on some morphological attributes. This link was nevertheless rather weak, suggesting that even if morphology may set limits to patterns of resource use, these limits are broad enough to allow fishes changing their choice of prey resources to respond to local biotic and/or abiotic conditions. Key words: Diet / Morphology / Phylogeny / Convergence / Tropical streams / Fishes / Bolivia Résumé -Relations entre le régime alimentaire et les caractéristiques morphologiques des peuplements de poissons de petits cours d'eau forestiers de l'Amazonie bolivienne. Nous avons analysé les relations entre le régime alimentaire et la morphologie de 30 espèces de poissons présentes dans de petits cours d'eau forestiers de l'Amazonie bolivienne. Après une analyse de leurs contenus stomacaux, les 30 espèces ont été réparties, dans un premier temps, dans huit grandes guildes trophiques. Dans un deuxième temps, après avoir analysé les éventuelles contraintes phylogénétiques, nous avons examiné, par analyse multivariée, les relations entre le régime alimentaire et la morphologie des espèces. Les résultats montrent que, indépendamment de la phylogénie, certaines des guildes trophiques peuvent être prédites d'après quelques attributs morphologiques (i.e. longueur relative de l'intestin, longueur standard et orientation de la bouche). Cela étant, ce lien entre régime alimentaire et caractéristiques morphologiques reste relativement faible, ce qui suggère que même si la morphologie limite les possibilités d'utilisation des ressources, cette limite est assez large pour permettre aux espèces de s'adapter à différentes conditions biotiques ou abiotiques locales.

“…Similar results were found in the North Taoxi River, in a mountain stream in the lower Yangtze River . Altitude is one of the most widely reported environmental factors determining habitat suitability and responsible for structuring the stream fish assemblages (Rahel & Hubert, 1991;Quist et al, 2006;Ferreira et al, 2007;Kadye et al, 2008;Pinto et al, 2009;Lorion et al, 2011;Li et al, 2012;MercadoSilva et al, 2012). The observed pattern is generally marked by a decrease in species diversity as altitude increases (Jaramillo-Villa et al, 2010).…”

The East Asian monsoon and related seasonal rain belts are assumed to be significantly variable at intraseasonal, interannual, and interdecadal time scales, and largely determine the hydrology and ecological processes of the streams and rivers in this region. This study investigated the spatiotemporal variation in fish assemblages and the relative importance of local habitat and regional landscape variables in two protected streams in the middle Yangtze River basin. We hypothesized that the stream fish assemblages in this area are strongly influenced by the monsoon climate, and display a spatiotemporal variation in response to changes of stream flow regimes and physical habitats. The results show that species richness and abundance varied with both season and stream size. The distance to the downstream confluence site was the top important environmental factor, followed by altitude and downstream link. The results suggest that the fish assemblages within this protected watershed are mainly affected by regional landscape variables such as longitudinal position and stream position, but less by local habitat variables including water temperature and habitat types. The study highlights the importance of tributary connectivity and continuity to stream fish diversity in this area, indicating that restoration activities should preferentially recover the connectivity between upstream and downstream.Handling editor: M.

“…Biotic zonation corresponds to discontinuities in river geomorphology or abiotic conditions promoting distinct assemblages along the longitudinal gradient (Huet, 1959;Schlosser, 1982;Balon et al, 1986;Rahel and Hubert, 1991;Oberdorff et al, 1993;Belliard et al, 1997). For example, species replacement may occur as a result of physiological specialization for temperature (Ferguson, 1958).…”
