dc.descriptionAGOSTINHO, Angelo Antonio; THOMAZ, Sidinei Magela; BALTAR, Solma L.S.M.A.; GOMES, Luiz Carlos. Influence of aquatic macrophytes on fish assemblages structure of the Upper Paraná. In: EWRS INTERNATIONAL SYMPOSIUM ON AQUATIC WEEDS, 11., 2002. Proceedings... Maâ, France, 2002. p.69-72.pt_BR
dc.description.abstractThe species richness, abundance and length composition of fishes were assessed inside and outside stands of macrophytes dominated by Eichhornia azurea in four semi-lentic habitats of the Upper Paraná River floodplain (Brazil), in different periods of the day. Species richness and abundance were consistently higher in the stand borders and lower outside. Mean length values were significantly higher in the open area. The structure pattern of the fish assemblage and its variation during a day can be explained by food resource availability, predation pressure and oxygen restrictions.en

dc.description.resumoLa richesse spécifique, l’abondance et la composition spécifique des poissons ont été observées à l’intérieur et à l’extérieur de bancs de macrophytes dominés par Eichhornia azurea dans 4 habitats semi-lentique de la plaine inondée du Haut Paraná (Brésil), et à différentes périodes du jour. La richesse spécifique et l’abondance étaient toujours plus élevées sur le bord des bancs de macophytes qu’à l’exterieur. Les longueurs moyennes étaient significativement plus élevées dans la zone ouverte. La structure de l’assemblage de poissons et ses variations au cours de la journée peuvent être expliquées par la disponibilité des ressources alimentaires, la pression de prédation et les restrictions en oxygène.fr
