“…However, the few studies that have examined the use of disturbance cues in predator learning have failed to provide support for this mechanism [34,35]. The results of the present study are similar to previous findings from freshwater fishes [34,35]: damselfish possess disturbance cues that are able to elicit increased anti-predator behaviour when detected; however, these cues do not mediate learned predator recognition. Some have argued that the absence of learning is due to the context in which disturbance cues are released.…”

Social learning of predators in the dark: understanding the role of visual, chemical and mechanical information

The ability of prey to observe and learn to recognize potential predators from the behaviour of nearby individuals can dramatically increase survival and, not surprisingly, is widespread across animal taxa. A range of sensory modalities are available for this learning, with visual and chemical cues being well-established modes of transmission in aquatic systems. The use of other sensory cues in mediating social learning in fishes, including mechano-sensory cues, remains unexplored. Here, we examine the role of different sensory cues in social learning of predator recognition, using juvenile damselfish (Amphiprion percula). Specifically, we show that a predator-naive observer can socially learn to recognize a novel predator when paired with a predator-experienced conspecific in total darkness. Furthermore, this study demonstrates that when threatened, individuals release chemical cues (known as disturbance cues) into the water. These cues induce an anti-predator response in nearby individuals; however, they do not facilitate learnt recognition of the predator. As such, another sensory modality, probably mechano-sensory in origin, is responsible for information transfer in the dark. This study highlights the diversity of sensory cues used by coral reef fishes in a social learning context.

“…Brown and Laland, 2001;Stunz and Minello, 2001;Young et al, 2008), exposing M. dalli to predators in the hatchery might increase their predator avoidance abilities, as has been shown in other species (e.g. Brown and Smith, 1998;Fu, 2015;Mirza and Chivers, 2000).…”

Estimating predation rates of restocked individuals: The influence of timing-of-release on metapenaeid survival

The success of aquaculture-based enhancement programs is greatly influenced by the survival of released individuals. Immediate post-release mortality through predation is one of the greatest obstacles to the success of releases, and the choice of a release site or time-of-release can be critical in maximising survival. This paper develops a novel quantitative method of estimating predation rate to inform release programs, and describes its use in determining whether hatchery-reared Western School Prawns Metapenaeus dalli should be released into the Swan-Canning Estuary in temperate south-western Australia during the night or day. and Atherinomorus vaigiensis (Atherinidae), were responsible for ~99 % of the predation, and that the total number of postlarval prawns consumed was 288 % higher at night than in the day. These findings suggest that releasing M. dalli during the day will greatly reduce predation and consequently allow a greater survival rate at this release site. The simple methodology developed here could be readily employed to inform release strategies for other species.

“…Hence, the inability of amphibian tadpoles to innately recognise chemical cues from exotic predatory turtles may represent a further competitive advantage for introduced turtles over native ones in the Iberian Peninsula (POLO-CAVIA et al, 2010b). However, the magnitude and impact of this evolutionary release on native populations of Iberian turtles remains uncertain, as amphibian prey might acquire learned recognition of novel competitive predators and enhance survival (MIRZA & CHIVERS, 2000;GAZDEWICH & CHIVERS, 2002;POLO-CAVIA & GOMEZ-MESTRE, 2014).…”

The red-eared slider, Trachemys scripta elegans, is a worldwide invasive species, currently introduced in most freshwater habitats as a consequence of the exotic pet trade. In the Iberian Peninsula, this American turtle is competing and displacing the Iberian turtles, Emys orbicularis and Mauremys leprosa. Recent studies have pointed out to diverse competitive advantages of sliders over Iberian terrapins. For instance, native turtles avoid chemical cues from T. scripta, which is more aggressive and dominant in direct competition for food and basking places. This avoidance behaviour displayed by Iberian terrapins might serve as a spacing mechanism to avoid unfavourable competitive interactions with the introduced species. Sliders also benefit from morphological and thermoregulatory advantages: they are more spherical, thus presenting a less surface to volume ratio and a greater thermal inertia that facilitates heat retention. On the other hand, introduced turtles show a more accurate assessment of predatory risk in altered habitats, and are more efficient predators of local prey than native species. These inter-specific asymmetries could contribute jointly to the greater competitive ability of introduced T. scripta, thus facilitating the expansion of this alien species in detriment of native populations of Iberian terrapins. Interferencias competitivas entre los galápagos nativos ibéricos y el galápago exótico Trachemys scripta. El galápago de Florida, Trachemys scripta elegans, es una especie invasora a nivel mundial, introducida en la mayor parte de los ecosistemas acuáticos como consecuencia del comercio masivo de mascotas. En la Península Ibérica, este galápago americano compite y desplaza a los galápagos ibéricos, Emys orbicularis y Mauremys leprosa. Estudios recientes han puesto de manifiesto la existencia de diversas ventajas competitivas del galápago de Florida sobre los galápagos nativos ibéricos. Por ejemplo, los galápagos nativos evitan ocupar espacios donde detectan secreciones químicas de los galápagos exóticos, quienes se muestran más agresivos y dominantes en la competencia directa por la comida y los recursos de asoleamiento. Este comportamiento aversivo podría ser utilizado por las especies nativas para evitar las interacciones competitivas desfavorables con la especie invasora. Los galápagos de Florida se benefician también de ventajas morfológicas y termorreguladoras: presentan una forma más esférica y por tanto una menor relación superficie-volumen y una mayor inercia térmica que facilita la retención de calor. Por otra parte, los galápagos exóticos muestran un mejor ajuste del riesgo de depredación en hábitats alterados y poseen ventajas en la captura de presas nativas. Estas asimetrías inter-específicas podrían contribuir conjuntamente a una mayor habilidad competitiva del galápa-go de Florida, facilitando la expansión de esta especie invasora en detrimento de las poblaciones nativas de galápagos ibéricos.
