“…In this case, there has been selection on the receiver to distinguish between these cues, but clearly not on the signaller to provide such information. In contrast, dietmediated chemical cues may contribute to the formation of social groups (Kleinhappel et al, 2014), in which case the nature of the chemical cue, as signal or cue, is ambiguous if signallers and receivers benefit from this behavior. Whether the following examples of diet-mediated signature mixtures would be better classified as diet-mediated signals or cues requires further investigation.…”

“…Accordingly, these early recognition behaviors in amphibians may be driven by preference for familiar food or habitat cues rather than kin recognition odors (Pfennig, 1990). The patterns for the fish may even be driven by the oddity effect, where shoaling with like individuals reduces the risk of predation (Kleinhappel et al, 2014).…”

Diet-Mediated Pheromones and Signature Mixtures Can Enforce Signal Reliability

Diet is arguably the most significant environmental factor shaping chemical signals in animals. In rare cases, dietary components are converted directly into pheromones or signature mixtures but more generally variation in an individual's diet influences their overall condition and thus capacity to synthesize the signal. Typically, diet is variable between individuals of the same species and this can lead to variation in signals. This variation presents specific challenges to receivers, who must be able to recognize and respond to a greater range of signals. However, such variation might also provide the receiver with key information about the signaller, allowing them to respond to the signal advantageously. Here we investigate how dietary-mediated pheromones and signature mixtures can provide the receiver with reliable information about the signaller, ultimately benefiting the receiver in a way not achievable by a static signal.

“…; Kleinhappel et al. ,b, ). One of the main reasons that chemical information is so widely utilised within social contexts is that it is temporally flexible over short time scales and can be rapidly influenced by factors such as diet and habitat (Doane & Porter ; Bryant & Atema ; Crosland ; Schellinck et al.…”

Free Amino Acids Mediate Association Preferences in Fish

et al. 2016

Chemical information is used in a variety of contexts including habitat recognition, foraging and predator avoidance, and a plethora of studies have shown that an individual's distinct chemical profile can mediate interactions with conspecifics. Interestingly, recent work has revealed that diet alone is sufficient to change the chemical profile of individuals, and with it, the way other individuals perceive and interact with them. Free amino acids are known to be utilised across species in a range of contexts, including during predator–prey and host–parasite interactions, and have been widely postulated to underpin diet‐mediated social interactions, especially in fish. However, so far no empirical evidence has been presented to support this suggestion. Using an established behavioural assay in three‐spined sticklebacks (Gasterosteus aculeatus), we aimed to assess association preferences in groups of fish fed experimental diets which differed by a single free amino acid. Our results demonstrate that free amino acids alone are sufficient to mediate interindividual association preferences, raising the possibility that such a mechanism may be widespread among aquatic animals.

“…Non‐random assortment can occur through a number of different mechanisms (Hoare et al, , b ; Krause et al, ). Animals may associate through active preference; shoaling fishes have been shown to form associations based upon a range of factors including body size (Ward & Krause, ; Croft et al, ), relatedness (Frommen & Bakker, ; Frommen et al, ; Piyapong et al, ), familiarity (Griffiths & Magurran, ; Croft et al ., ; Frommen & Bakker, ; Ward et al, ), chemical cues derived from similar diet or habitat use patterns (Ward et al, , , , ; Webster et al, , , b; Kleinhappel et al, , ) and competitive ability (Metcalfe & Thomson, ). Assortment may also arise passively through shared habitat preference or site fidelity (Croft et al, ; Webster et al, ; Ward et al, ), similar swimming speeds (Krause et al, ) or similar patterns of activity, risk aversion or cover use linked to personality traits (Pike et al, ; Croft et al, ).…”

We investigated the consistency of association network structure for groups of sticklebacks Gasterosteus aculeatus. Each group was observed twice and we varied the duration between observations and the size of the experimental arena that they were observed in. At the dyad level, we found positive correlations between dyad interaction frequencies across observations. At the group level we found variation in four network metrics between observations, but only in treatments where the duration between observations was short. Specifically, fish formed more and smaller groups in the second observation in this treatment. Fish were also organized into more subunits in the larger arenas. Finally, we saw positive correlations between some group network metrics across observations suggesting relative consistency at the group level. There are several processes that might drive these interaction patterns. Our findings have implications for experimental design and the comparison and integration of findings of experiments from different studies carried out under different conditions.
