Abstract: The influence of habitat, biomass of herbaceous vegetation, depth and distance from permanent water bodies on the structure of fish assemblages of a seasonal floodplain was evaluated using data collected along 22 transects in an area of 25 km 2 in the floodplain of Cuiabá River, Pantanal, Brazil. Each transect was sampled for fish using throw traps and gillnets during the flood period of 2006. Multivariate multiple regression analysis and multivariate analysis of covariance indicated that depth was the only va… Show more

“…Hence, the common occurrence of Hypessobrycon, Serrapinnus, Astyanax and Hoplosternum littorale in this study -also verified by Okada et al (2003) in temporary ponds in the dry season of the upper Paraná river (Brazil) -indicates a widespread adaptation and survival of these groups of species in ephemeral habitats subject to environmental stress. Also, the great abundance and widespread occurrence of Hyphessobrycon elachys and Serrapinnus calliurus shows that the stress caused by the drying process does not limit the successful occupation of these species in temporary ponds, as noted by Fernandes et al (2010a) in the same region and by Cunico et al (2002) in the upper Paraná river (Brazil). Moreover, the richness found in a single sampling represented almost 60% (49 species and 1117 individuals) of the richness registered by Fernandes et al (2010a) for the same region during a one-month collection using two methods (throw trap and gill net), thus emphasising the effectiveness of the sampling method for the study of fish fauna in rapid assessment of floodplain biodiversity.…”

“…Studies on temporary floodplain environments have verified that depth and hydroperiod are the main influential factors on the structure of the assemblages in these environments (Baber et al, 2002;Pazin et al, 2006;Fernandes et al, 2010a). This indicated that the influence of depth on composition is due not only to morphological and behavioural adaptations of the species, but also to the survival probability related to hydroperiod variation.…”
