Jamming avoidance in electric fish and frogs: strategies of signal oscillator timing. 1986

R Zelick

Repetitive spontaneous calling in frogs and electric signalling in pulse-type electric fishes are driven by neural pacemakers. Minimization of signal overlap between neighbors is achieved in frogs and certain electric fishes by mutual entrainment, requiring cycle-by-cycle adjustment of pacemaker interval. Other fishes, which require a regular electric organ discharge, are more constrained in their ability to avoid jamming. Entrainment may also serve to reciprocally place signals in a temporal 'blindspot' of the receiver, the period of elevated sensory threshold following signal production, to reduce aggressive interactions.

UI	MeSH Term	Description	Entries
D004555	Electric Fish	Fishes which generate an electric discharge. The voltage of the discharge varies from weak to strong in various groups of fish. The ELECTRIC ORGAN and electroplax are of prime interest in this group. They occur in more than one family.	Mormyrid,Mormyridae,Elephantfish,Elephantfishes,Fish, Electric,Mormyrids
D004560	Electricity	The physical effects involving the presence of electric charges at rest and in motion.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000819	Animal Communication	Communication between animals involving the giving off by one individual of some chemical or physical signal, that, on being received by another, influences its behavior.	Animal Communications,Communication, Animal,Communications, Animal
D001001	Anura	An order of the class Amphibia, which includes several families of frogs and toads. They are characterized by well developed hind limbs adapted for jumping, fused head and trunk and webbed toes. The term "toad" is ambiguous and is properly applied only to the family Bufonidae.

D013016	Sound	A type of non-ionizing radiation in which energy is transmitted through solid, liquid, or gas as compression waves. Sound (acoustic or sonic) radiation with frequencies above the audible range is classified as ultrasonic. Sound radiation below the audible range is classified as infrasonic.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
