Electrosensory Contrast Signals for Interacting Weakly Electric Fish [PDF]
Frontiers in Integrative Neuroscience, 2019 Active sensory systems have evolved to properly encode natural stimuli including those created by conspecifics, yet little is known about the properties of such stimuli. We consider the electrosensory signal at the skin of a fixed weakly electric fish in

Dominance in Habitat Preference and Diurnal Explorative Behavior of the Weakly Electric Fish Apteronotus leptorhynchus [PDF]
Frontiers in Integrative Neuroscience, 2019 Electrocommunication and -localization behaviors of weakly electric fish have been studied extensively in the lab, mostly by means of short-term observations on constrained fish.

Molecular evolution of the ependymin-related gene epdl2 in African weakly electric fish [PDF]
G3: Genes, Genomes, Genetics, 2022 Gene duplication and subsequent molecular evolution can give rise to taxon-specific gene specializations. In previous work, we found evidence that African weakly electric fish (Mormyridae) may have as many as three copies of the ...

Tracking spatial patterns and daily modulation of behavior in a natural population of the pulse-type weakly electric fish, Gymnotus omarorum [PDF]
iScienceSummary: Tracking individual spatial and activity-rest patterns in natural populations is challenging because it is seldom possible to monitor individual-specific traits continuously.

A new genome assembly of an African weakly electric fish (Campylomormyrus compressirostris, Mormyridae) indicates rapid gene family evolution in Osteoglossomorpha [PDF]
BMC Genomics, 2023 Background Teleost fishes comprise more than half of the vertebrate species. Within teleosts, most phylogenies consider the split between Osteoglossomorpha and Euteleosteomorpha/Otomorpha as basal, preceded only by the derivation of the most primitive ...

A History of Corollary Discharge: Contributions of Mormyrid Weakly Electric Fish [PDF]
Frontiers in Integrative Neuroscience, 2020 Corollary discharge is an important brain function that allows animals to distinguish external from self-generated signals, which is critical to sensorimotor coordination.

Transcriptome-wide single nucleotide polymorphisms related to electric organ discharge differentiation among African weakly electric fish species. [PDF]
PLoS ONE, 2020 African weakly electric fish of the mormyrid genus Campylomormyrus generate pulse-type electric organ discharges (EODs) for orientation and communication. Their pulse durations are species-specific and elongated EODs are a derived trait.

The Use of Supervised Learning Models in Studying Agonistic Behavior and Communication in Weakly Electric Fish [PDF]
Frontiers in Behavioral Neuroscience, 2021 Despite considerable advances, studying electrocommunication of weakly electric fish, particularly in pulse-type species, is challenging as very short signal epochs at variable intervals from a few hertz up to more than 100 Hz need to be assigned to ...

Gene and allele-specific expression during electric organ ontogeny in African weakly electric fish (Campylomormyrus) [PDF]
Communications BiologyThe African weakly electric fish use their muscle-derived electric organ to produce electric organ discharge (EOD) for electrocommunication and electrolocation.
