Abstract The Amazon Basin is an unquestionable biodiversity hotspot, containing the highest freshwater on earth and facing off a recent increase in anthropogenic threats. current knowledge spatial distribution of fish species greatly deficient this basin, preventing comprehensive understanding hyper-diverse ecosystem as whole. Filling gap was priority transnational collaborative project, i.e . AmazonFish project - https://www.amazon-fish.com/ Relying outputs we provide most complete records...
Identifying the main taxonomic, phylogenetic and trait dimensions of beta diversity, evaluating their prospective drivers, advances our understanding patterns processes involved in evolution biological assemblages. Using comprehensive databases on distribution, phylogeny, morphological traits (later referred as functional traits) Amazonian freshwater fishes, we analyzed diversity these three to evaluate historical contemporary drivers. We mostly focused pure turnover components (Taxoβsim,...
Abstract The seasonality of tropical rivers, induced mainly by water level changes, shapes many interrelated aspects ecological communities and the populations they contain, including animal movement, feeding, growth, reproductive activity. However, role played in structuring diversity assemblages is not yet fully understood. We examined effects on community structure composition benthic fish comparing two consecutive receding rising seasons a major tributary Amazon basin. quantified...
Fish assemblages from two sandy beaches in the lower Purus river (Amazonas, Brazil) were compared. Four sampling groups represented by: day and night samples beach inside Reserva Biológica de Abufari (biological reserve) Desenvolvimento Sustentável Piagaçu-Purus (sustainable development reserve). Samples collected during low water levels (November) 2007. The fish sampled by means of seines with mesh size 5 mm between opposing knots, 11 m long 6 wide. A total 112 species belonging to nine...
Abstract Despite the high number of fish species described for Amazon region, ichthyofauna that inhabits depths main channels large tropical rivers is one least known. In order to know diversity patterns these in whitewater Central Amazon, we used data from channel benthic assemblage Japurá, Purus and Madeira tested hypothesis there are marked spatial seasonal differences composition community among them. For this, a multivariate dispersion test, total β its decomposition into local (LCBD)...
The objective of this study was to assess if larvae Phylloicus spp. show any preference for leaves with or without microorganisms when building cases. Two experiments were realized at municipality Presidente Figueiredo (Amazonas – Brazil), containing treated Hydrogen peroxide (H2O2), a compost that has an antimicrobial action, and another one untreated leaves. In the first observed case-building by And in second tested monitored during 24 hours statistical analysis used t-test. Were not...
Studies of fish assemblages have demonstrated that the main channels rivers contain ichthyofauna adapted to this environment. However, information regarding effects temporal and spatial variations on is scarce. Using data from benthic in a major tributary Amazon basin collected during two consecutive receding rising water seasons, we tested hypothesis there are marked community composition between seasons. An asymmetry predictability was detected among samples Predictability terms species...
Apesar das praias serem consideradas um dos sete mais importantes habitats aquáticos da Amazônia, poucos trabalhos foram realizados quanto ao levantamento de sua ictiofauna, principalmente quando utilizados diferentes apetrechos coleta. Este trabalho teve como objetivo comparar a eficiência relativa dois apetrechos, rede cerco e malhadeira, ambos forma ativa (arrasto), em três localizadas no baixo rio Purus. A apresentou maior número espécies indivíduos capturados, entanto, malhadeira...
