Conspecific and heterospecific alarm substance induces behavioral responses in piau fish Leporinus piau
(SPRINGER HEIDELBERG, 2010)
In ostariophysan fish, the detection of alarm substance released from the skin of a conspecific or a sympatric heterospecific may elicit alarm reactions or antipredator behavioral responses. In this study, experiments were ...
Mianserin affects alarm reaction to conspecific chemical alarm cues in Nile tilapia
(2017-02-01)
In this study, I show that mianserin, a chemical with serotonin and adrenoceptor antagonist activities, increases fish vulnerability to a potential predator threat, when prey fish must deal with this threat based on ...
Chemical cues related to conspecific size in pintado catfish, Pseudoplatystoma coruscans
(Springer, 2005-12-01)
The pintado (Pseudoplatystoma coruscans) is a ferocious carnivorous catfish with evident cannibalistic behaviour; its nocturnal habits are related to its ability to use predominately chemical sensorial modalities. This ...

Testing the dear enemy relationship in fiddler crabs: Is there a difference between fighting conspecific and heterospecific opponents?
(2019-05-01)
Reduction of aggressiveness toward familiar neighbors, when compared to aggressiveness toward unfamiliar strangers, can decrease the costs of territory defense. This phenomenon is known as the “dear enemy effect”. Individuals ...
Immunological stress in rats induces bodily alterations in saline-treated conspecifics
(Pergamon-elsevier Science LtdOxfordInglaterra, 2000)
Testing the functionality of lipids from feces in the conspecific recognition of the weeping lizard, Liolaemus chiliensis
(Society for the Study of Amphibians and Reptiles, 2020-12-16)
Pheromones, a mix of proteins and lipids, are involved in lizards’ conspecific recognition. In our study, we specifically address whether fecal lipids are involved in conspecific recognition of the Weeping Lizard, Liolaemus ...
Time-place learning in the zebrafish (Danio rerio)
(Elsevier, 2018)
Dissecting the brain`s fear system reveals the hypothalamus is critical for responding in subordinate conspecific intruders
(NATL ACAD SCIENCES, 2009)
Effective defense against natural threats in the environment is essential for the survival of individual animals. Thus, instinctive behavioral responses accompanied by fear have evolved to protect individuals from predators ...
Hunger suppresses the onset and the freezing component of the antipredator response to conspecific skin extract in pintado catfish
(Brill Academic Publishers, 2001-10-01)
Although the skin of an injured conspecific releases alarm substance in some fish species, it has been shown that such damage induces feeding behaviour rather than an alarm reaction under conditions of food scarcity. We ...
