Studies of pulse-type gymnotiform electric fishes have suggested that electric organ discharge waveforms (EODw) allow individuals to discriminate between conspecific and allospecific signals, but few have approached this experimentally. Here we imple

A new species of the bluntnose knifefish genus Brachyhypopomus Mago-Leccia is described from headwaters of upper Rio Juruena, and upper Rio Machado, Amazon basin, Brazil. The new species differs fr...

We quantified patterns of circannual reproductive breeding periodicity in a multi-species assemblage of the gymnotiform knifefish genus Brachyhypopomus from Amazonian floodplain and terra firme stream habitats. We applied linear mixed-effect models a

Some fish communicate using pulsatile, stereotyped electric organ discharges (EODs) that exhibit species- and sex-specific time courses. To ensure reproductive success, they must be able to discriminate conspecifics from sympatric species in the mudd

Signal plasticity can maximize the usefulness of costly animal signals such as the electric organ discharges (EODs) of weakly electric fishes. Some species of the order Gymnotiformes rapidly alter their EOD amplitude and duration in response to circa

We describe the anatomy and histology of the accessory electric organs of several knifefish taxa. Accessory electric organs are observed among Rhamphichthyoidea in the opercular, mental and humeral regions. Within this group, some species of Brachyhy

Agonistic aggression has provided an excellent framework to study how conserved circuits and neurochemical mediators control species-specific and context-dependent behavior. The principal inhibitory control upon aggression is serotonin (5-HT) depende
