The scent of stress: Pintado catfish differentially respond to chemical cues from stressed conspecifics
(Brill Academic Publishers, 2012-01-01)
We examined whether pintado catfish (Pseudoplatystoma corruscans) can discriminate between scents of non-injured conspecifics stressed by a predator or by confinement and how fish use this information in the trade-off ...
The effect of conspecific density on emergence of Lestes bipupillatus calvert, 1909 (Odonata: Lestidae)
(2014)
Conspecific density may influence adult recruitment and consequently population dynamics. Several studies have shown the density dependence of larvae growth rates in Odonata. However, few studies studied how conspecific ...
Field tests of carbon dioxide and conspecifics as baits for Mepraia spinolai, wild vector of Chagas disease
(2002)
In spite of extensive evidence showing an association between host stimuli and insect finding behaviour, the importance of carbon dioxide in attracting Triatominae is not entirely understood. We assessed the potential of ...
The influence of tadpole density and predation on the behavioral responses of two Neotropical anurans
(Universidade de Sao Paulo, 2019-12)
The risk of predation can prompt a variety of responses from the prey species, including changes in morphology, life history, and behavior. Adaptive responses to predators may depend on the amount of resources available ...
Color pattern variation in Trichomycterus iheringi (Eigenmann, 1917) (Siluriformes: Trichomycteridae) from rio Itatinga and rio Claro, São Paulo, Brazil
(2010-03-31)
Color pattern is recognized as an important characteristic for diagnosing Trichomycterus species and for elucidating their relationships. An analysis based on morphological and molecular data confirms the existence of a ...
Social reinstatement responses of meat-type chickens to familiar and unfamiliar conspecifics after exposure to an acute stressor
(Elsevier Science, 2008-04)
Runway tests are considered indicative of underlying sociality in birds and their ability to make social discriminations. We evaluated whether experience of a prior stressor alters the subsequent affiliation responses of ...
NEURAL CORRELATES OF SCENT MARKING BEHAVIOR IN C57BL/6J MICE: DETECTION AND RECOGNITION OF A SOCIAL STIMULUS
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Mice show urinary scent marking behavior as a form of social communication. Marking to a conspecific stimulus mouse or odor varies with stimulus familiarity, indicating discrimination of novel and familiar animals. This ...
Chemical blindness in Liolaemus lizards is counterbalanced by visual signals, the case of two species with different communication modalities
(Brill Academic Publishers, 2020-02)
Animals employ a wide variety of communication tactics that rely on distinct sensory modalities. Lizards are characterized by their heightened dependence on chemical and visual communication. Some authors have proposed ...
Conspecific food competition explains variability in colony size: a test in magellanic penguins
(Ecological Society of America, 2002-12)
Food availability has been proposed as one of the main factors regulating population sizes in birds. Seabirds have provided evidence for the hypothesis that food depletion due to intraspecific competition explains variability ...
