Unusual effect of chemical communication on social aggression in juvenile cichlid fish Cichlasoma paranaense (Cichliformes: Cichlidae)

The test of chemical signaling on social groups of juvenile cichlid Cichlasoma paranaense by renewing the water in the aquarium apparently reduced aggressive interactions in this species, indicating an interspecific difference on the aggressive response to chemical variation in the social environment.

Chemical signals act as the main reproductive barrier between sister and mimetic Heliconius butterflies

It is suggested that pheromones are the major reproductive barrier opposing gene flow between these two sister and co-mimic species, and not wing colour pattern drive the preference of females by conspecific males.

To pee or not to pee: urine signals mediate aggressive interactions in the cooperatively breeding cichlid Neolamprologus pulcher

Chemical communication plays a crucial role in multimodal communication of aggression in these fish, which highlights the need of studying the role of chemical communication during agonistic encounters in general, even if other signals are more obvious to the human observer.

Nestling tree swallows ( Tachycineta bicolor ) alter begging behaviour in response to odour of familiar adults, but not their nests

It is found that begging responses of nestlings did not differ in response to orange oil odour or water, but nestlings begged significantly longer and more intensely in response than an unfamiliar adult, regardless of adult sex, providing evidence that tree swallows use chemical cues to alter their behaviour.

Evolutionary dynamics of pre- and postzygotic reproductive isolation in cichlid fishes

Cichlid fishes are exceptionally species-rich, speciated at explosive rates and, hence, are a model system in speciation research. Yet, their reproductive isolating barriers have, so far, not been

Wasteful carotenoid coloration and its effects on territorial behavior in a cichlid fish

The results suggest that intimidation by wide bars as well as correlations between bar width and explorative behavior may contribute to mediating success in territorial Tropheus “Ikola”.

Aggressive communication in aquatic environments

The importance of studying the role of multimodal communication during aggressive encounters in general is highlighted and the importance of understanding aquatic communication in the light of conservation and animal welfare issues is discussed.

Sympatric and allopatric Alcolapia soda lake cichlid species show similar levels of assortative mating

The relatively weak assortative mating in sympatry suggests that additional reproductive barriers, such as microhabitat preferences or spatial structuring may contribute to genetic isolation in nature.

Urine as a social signal in the mozambique tilapia (Oreochromis mossambicus).

To test whether this species is actively signalling to conspecifics or the olfactory sensitivity evolved as a form of chemical spying, the current study assessed changes in urination rates of both sexes in different social contexts.

Female preference for conspecific males based on olfactory cues in a Lake Malawi cichlid fish

The relative importance of visual and olfactory cues in mate recognition by females of a Lake Malawi cichlid species is compared to suggest that divergence ofOlfactory signals may have been an important influence on the explosive radiation of the East African species flock.

Nocturnal Mate Recognition and Nest guarding by Female Convict Cichlids (Pisces, Cichlidae: Cichlasoma mgrofasciatum)

Active nest defense at night shows that the convict cichlid, normally considered to be diurnal, can engage in coordinated and effective behaviour in the absence of light.

The response of convict cichlids to chemical alarm cues: an integrated study of behaviour, growth, and reproduction

Predation is an important agent leading to the evolution of accurate risk assessment. In fishes, one of the best studied modes of threat assessment is the use of damage release cues from consumed or

Olfactory self-recognition in a cichlid fish

Interestingly, males (at least outbred ones) preferred the odor of an unfamiliar, unrelated male over that of a familiar brother, maybe to avoid competition with kin.

The Role of Urine in Parent-Offspring Communication in a Cichlid Fish

The fry of the Midas cichlid preferred over blank water, a urine solution from either parent or from a nonparental adult of either sex, and this high acuity implies that olfaction rather than gustation mediated the chemosensory responses described above.
