Electroreception, the capacity to detect external underwater electric fields with specialised
receptors, is a phylogenetically widespread sensory modality in fishes and amphibians. In …

Agonistic behavior has shaped sociality across evolution. Though extremely diverse in types
of displays and timing, agonistic encounters always follow the same conserved phases …

Fish populations are increasingly being subjected to anthropogenic changes to their
sensory environments. The impact of these changes on inter-and intra-specific …

Highlights•Multimodal communication allows a shift of channels if one channel is
impaired.•Shifts can occur only in perception or in both signal production and …

The study of multimodal communication has become an active and vibrant field. This special
issue of Behavioral Ecology and Sociobiology brings together new developments in this …

Males and females commonly compete for limited resources. When interaction costs are
similar for both sexes and there are no sexual differences in resource value estimation, a …

To understand the evolution of sexually dimorphic communication signals, we must quantify
their costs, including their energetic costs, the regulation of these costs, and the difference …

The bluntnose knifefish genus BrachyhypopomusMago-Leccia, 1994, is diagnosed from
other Rhamphichthyoidea (Rhamphichthyidae+ Hypopomidae) by the presence of a disk …

The communication behaviors of vocal fish and electric fish are among the vertebrate social
behaviors best understood at the level of neural circuits. Both forms of signaling rely on …

Aggressive behaviors are widespread among animals and are critical in the competition for
resources. The physiological mechanisms underlying aggression have mostly been …
