Social interactions between live and artificial weakly electric fish: Electrocommunication and locomotor behavior of Mormyrus rume proboscirostris towards a mobile dummy fish. [PDF]

open access: yesPLoS ONE, 2017
Mormyrid weakly electric fish produce short, pulse-type electric organ discharges for actively probing their environment and to communicate with conspecifics.

Electrocommunication in pulse Gymnotiformes: the role of electric organ discharge (EOD) time course in species identification [PDF]

open access: yes, 2020
Understanding how individuals detect and recognize signals emitted by conspecifics is fundamental to discussions of animal communication. The species pair Gymnotus omarorum and Brachyhypopomus gauderio, found in syntopy in Uruguay, emit species-specific ...

Differentiation of courtship songs in parapatric sibling species of dwarf stonebashers from southern Africa (Mormyridae, Teleostei) [PDF]

open access: yes, 2006
We describe the nocturnal courtship songs of male dwarf stonebashers, Pollimyrus castelnaui, from the Okavango River and its inland delta. We examined the question of whether the songs are sufficiently differentiated from those of its parapatric sibling ...

Waveform generation in the weakly electric fishGymnotus coropinae(Hoedeman): the electric organ and the electric organ discharge [PDF]

open access: yesJournal of Experimental Biology, 2009
SUMMARYThis article deals with the electric organ and its discharge in Gymnotus coropinae, a representative species of one of the three main clades of the genus. Three regions with bilateral symmetry are described: (1)subopercular (medial and lateral columns of complex shaped electrocytes); (2)abdominal (medial and lateral columns of cuboidal and ...

The sensory effects of light on the electric organ discharge rate of Gymnotus omarorum [PDF]

open access: yes, 2023
Gymnotiformes are nocturnal fishes inhabiting the root mats of floating plants. They use their electric organ discharge (EOD) to explore the environment and to communicate.

Male-mediated species recognition among African weakly electric fishes [PDF]

open access: yesRoyal Society Open Science, 2018
Effective communication among sympatric species is often instrumental for behavioural isolation, where the failure to successfully discriminate between potential mates could lead to less fit hybrid offspring.

Design and construction of an Electric Fish Finder

open access: yesNeotropical Ichthyology
We provide notes on the design and construction of an Electric Fish Finder - a portable differential amplifier for detecting the electrostatic fields of gymnotiform knifefishes.

A JAR of Chirps: The Gymnotiform Chirp Can Function as Both a Communication Signal and a Jamming Avoidance Response

open access: yesFrontiers in Integrative Neuroscience, 2019
The weakly electric gymnotiform fish produce a rhythmic electric organ discharge (EOD) used for communication and active electrolocation. The EOD frequency is entrained to a medullary pacemaker nucleus. During communication and exploration, this rate can

A model for studying the energetics of sustained high frequency firing. [PDF]

open access: yesPLoS ONE, 2018
Regulating membrane potential and synaptic function contributes significantly to the energetic costs of brain signaling, but the relative costs of action potentials (APs) and synaptic transmission during high-frequency firing are unknown.

Comparative histology of the adult electric organ among four species of the genus Campylomormyrus (Teleostei: Mormyridae) [PDF]

open access: yes, 2015
The electric organ (EO) of weakly electric mormyrids consists of flat, disk-shaped electrocytes with distinct anterior and posterior faces. There are multiple species-characteristic patterns in the geometry of the electrocytes and their innervation.
