“…Moreover, their responses to each predator evidently differed depending on the quality of the fish diet. Contrary to our findings, Paterson et al (2013) in their meta-analysis of responses of aquatic invertebrates to predator cues concluded that predator diet does not influence antipredatory behaviour of prey. This discrepancy can be accounted for by the peculiarity of the species tested in our study.…”

“…(MacNeil et al, 1997), exudates of a top predator and/or conspecific alarm substances may contain ambiguous information not only on the predation risk, but also on the vicinity of a potential food source, as postulated (though not demonstrated) by Paterson et al (2013). This phenomenon, however, has not been fully confirmed by experimental studies yet.…”

“…This speculation cannot be fully resolved without a direct comparison to non-invasive species. However, Paterson et al (2013) has demonstrated that such differentiation by aquatic invertebrates is an exception, rather than a rule. On the other hand, different responses of prey to various predation cues, i.e.…”

“…Thus, the feeding habits of D. villosus clearly depend on a number of factors, such as the community structure (Hellmann et al, 2015) or temperature (van der Velde et al, 2009). Notwithstanding these discrepancies, it can perceive the presence of a fish not only as a danger, but also as information about potential food resources (Paterson et al, 2013), especially if the fish consumed chironomids-an important part of the diet of invasive amphipods (Bacela-Spychalska & van der Velde, 2013). Amphipods were found to assimilate and grow better on chironomids than on plant food (Gergs & Rothhaupt, 2008), thus chironomids seems likely to be their preferred food type.…”

“…We hypothesized that for omnivorous and cannibalistic amphipods (Dick & Platvoet, 2000;BacelaSpychalska & van der Velde, 2013), exudates of predators fed particular types of diets might also contain attractants indicating the increased availability of food resources (Wisenden et al, 2009;Paterson et al, 2013). This would reveal a dual nature of a predator cue, as information on both potential danger and availability of food.…”

Detection of chemical cues of predators and food resources is a key for the behaviour of many species in aquatic ecosystems. We checked whether predator origin and diet, containing potential food and/ or alarm signals, affect the behaviour of omnivorous prey partly sharing their diet with a top predator. We conducted y-maze experiments to study the responses of invasive omnivorous and cannibalistic amphipods (Dikerogammarus villosus and Pontogammarus robustoides) to chemical cues of fish predators, injured amphipods and chironomid larvae (common amphipod food). As the predators, we used the goby Babka gymnotrachelus (sympatric with the amphipods) and piranha Pygocentrus nattereri (allopatric to the amphipods). The fish were either starved or fed amphipods or chironomids. D. villosus preferred predators fed chironomids and conspecifics as well as crushed conspecifics and chironomids, but avoided both hungry predators. Thus, D. villosus may perceive the presence of a top predator as an indication of both food resource and predation risk. P. robustoides avoided predators fed both amphipods (particularly conspecifics) and their alarm substances. The responses of both species depended more on the predator diet than on its species, which is likely to facilitate the recognition of allopatric predators and survival in newly invaded areas.

Infochemicals act as inter‐ or intraspecific messengers. The literature suggests complex interactions between infochemicals (mainly predator cues) and chemical (e.g., pesticide) effects, with their direction and magnitude depending on the cue origin, pesticide identity, and test species. With the present study we assessed the impact of alarm cues alone and in combination with the neonicotinoid insecticide thiacloprid on leaf consumption, predation on Baetis nymphs, and dry weight of the amphipod Gammarus fossarum. Alarm cues (ground gammarids) and thiacloprid alone decreased gammarid leaf consumption with increasing intensities. At a defined alarm cue intensity, which alone did not cause a significant reduction in gammarid feeding, thiacloprid‐induced feeding effects were additive. During an experiment targeting gammarid predation on Baetis nymphs (120 h), thiacloprid and alarm cues alone did increase and reduce predation significantly, respectively. Moreover, alarm cues led to a lower final gammarid dry weight. However, alarm cues did not affect response variables during a second predation experiment performed at a higher thiacloprid concentration (2 vs 0.75 µg/L). This discrepancy in alarm cue effects highlights either a varying susceptibility of the test species to these cues among experiments or that cue quality is fluctuating. Thus, the present study highlights a considerable variability in the individual and interactive effects of infochemicals and chemical stressors on aquatic biota, an insight relevant in the assessment of multiple stressors.
