Simultaneous abrupt shifts in hydrology and fish assemblage structure in a floo...
Röpke, Cristhiana Paula; Amadio, Sidinéia Aparecida; Zuanon, Jansen; Ferreira, Efrem J.G.; Deus, C. P.; Pires, Tiago H.S.; Winemiller, Kirk O.Combined effects of climate change and deforestation have altered precipitation patterns in the Amazon. This has led to changes in the frequency of extreme events of flood and drought in recent decades and in the magnitude of the annual flood pulse, a phenomenon that influences virtually all aspects of river-floodplain ecosystem dynamics. Analysis of long-term data revealed abrupt and synchronous changes in hyd...
Intertidal life: Field observations on the clingfish gobiesox barbatulus in sou...
Pires, Tiago H.S.; Gibran, F. Z.The clingfish Gobiesox barbatulus shows nocturnal feeding activity, spending most part of the day stationary and adhered to the inferior part of stones. To feed, this species uses the sit-and-wait and particulate feeding tactics. It shows a carnivorous feeding habit mostly consuming small benthic crustaceans. It can move in two ways: (1) "stone-by-stone", sliding its ventral sucker disc across each stone and (2...
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...
