Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Colonização por peixes no folhiço submerso: implicações das mudanças na cobertu...
Mortati, Amanda FredericoA ictiofauna de igarapés de terra firme na Amazônia Central mantém estreita relação com a vegetação ripária, pois depende energética e estruturalmente do material orgânico originado da floresta. Os bancos de folha, formados em remansos ou zonas de maior correnteza, são colonizados por uma rica fauna que busca nesses locais abrigo ou alimento. Neste sentido, procurei avaliar se o tamanho dos igarapés e o tipo de...
Trends in studies of Brazilian stream fish assemblages
Dias, Murilo Sversut; Zuanon, Jansen; Couto, Thiago B. A.; Carvalho, Marla S.; Carvalho, Lucélia Nobre; Espírito-Santo, Helder Mateus VianaStudies about fish assemblages in Brazilian streams have grown in recent years, however, it remains unclear whether this increase is followed by increments in the diversity of addressed topics and theoretical frameworks adopted by researchers. We performed a systematic search for Brazilian studies on stream fish assemblages recording study region, publication year, objectives, and spatial and temporal scales ad...
Riparian deforestation affects the structural dynamics of headwater streams in ...
Bleich, Monica Elisa; Mortati, Amanda Frederico; André, Thiago; Piedade, Maria Teresa FernandezComparative studies of streams with altered versus conserved riparian zones are important to evaluate the degree of alterations caused by inappropriate use of these streams’ vital buffer zones. The aim of this study was to determine the impact of riparian deforestation on the habitat structure of southern Brazilian Amazonian headwater streams, as well as to provide elements for impact assessment and the monitor...
