“…information may lead to reduced offspring fitness (Bonduriansky et al, 2012). In T. oceanicus, females reared without exposure to male acoustic sexual signals display greater levels of mate searching behaviour to maximise their chances of mating in the low-male density environment (Bailey & Zuk, 2008;Ghalichi et al, 2020). However, our data showed that when both parents were reared in 'song', their 'no-song'-reared daughters did not display this adaptive behavioural plasticity, instead exhibiting low levels of mate searching.…”

“…Previous studies have shown that, when reared in a low-male density environment, female T. oceanicus exhibit an adaptive increase in their mate searching behaviour, moving further and more quickly in search of song to access potentially rare mating opportunities (Bailey & Zuk, 2008;Ghalichi et al, 2020;Swanger & Zuk, 2015).…”

“…Males that are kept for 1 week in the absence of male song display significantly greater levels of activity than males accustomed to competition (Rudin et al, 2018). Moreover, females reared in a song-less environment are more responsive to additional mating opportunities, moving further and more quickly in search of song in phonotactic trials (Bailey & Zuk, 2008;Ghalichi et al, 2020). Behavioural plasticity in mate searching behaviour is therefore likely adaptive, allowing females that develop in an environment where potential mates are scarce to achieve the additional matings that are known to enhance fitness (Garcia-gonzalez & Simmons, 2007;Simmons, 2001).…”

Nongenetic inheritance of behavioural variability is context specific and sex specific

1. Environmentally mediated nongenetic inheritance extends the concept of phenotypic plasticity across generations, allowing for the experience of parents to influence the physiology, life history and behaviour of their offspring.2. We assess whether the perceived social environment of mothers and fathers impacts offspring behaviour in the Australian field cricket Teleogryllus oceanicus.3. We varied parents' perception of the density of conspecific males by exposing parents to either the presence or absence of male song throughout rearing. Following mating in a factorial design, the offspring of the parental pairs were also reared across the two acoustic environments and their behaviour assessed as adults.4. When reared in a no-song environment, offspring of both sexes were more active, emerging from a shelter sooner and displaying greater mobility in search of male song. 5. Offspring behaviour was not directly impacted by either the maternal or paternal social environments independently, but there was a significant interaction effect between the parental environments on the behaviour of daughters. When both parents were reared in song ('paternal song × maternal song'), their no-song-reared daughters exhibited lower levels of mobility than the no-song-reared daughters of 'paternal song × maternal no-song' and 'paternal no-song × maternal song' pairs. 6. Although our data suggest that nongenetic parental effects may have the potential to drive behavioural variability in offspring, such effects are highly complex, only arising as sex-and context-specific traits.

“…This simple observation has since been borne out in a wealth of empirical tests [10][11][12], while more recent efforts have built on these foundations to highlight predation as a selective force in sexual systems more generally. In ecological terms, predation-induced shifts in signalling behaviour [13,14] and mate choice [15,16] are now well documented, while at evolutionary scales the need to balance between signalling to conspecifics and avoiding predators can culminate in genetic polymorphisms [17,18] and population divergence [19,20].…”

The exploitation of sexual signals by predators: a meta-analysis

2022

Sexual signals are often central to reproduction, and their expression is thought to strike a balance between advertising to mates and avoiding detection by predatory eavesdroppers. Tests of the predicted predation costs have produced mixed results, however. Here we synthesized 187 effects from 78 experimental studies in a meta-analytic test of two questions; namely, whether predators, parasites and parasitoids express preferences for the sexual signals of prey, and whether sexual signals increase realized predation risk in the wild. We found that predators and parasitoids express strong and consistent preferences for signals in forced-choice contexts. We found a similarly strong overall increase in predation on sexual signallers in the wild, though here it was modality specific. Olfactory and acoustic signals increased the incidence of eavesdropping relative to visual signals, which experienced no greater risk than controls on average. Variation in outcome measures was universally high, suggesting that contexts in which sexual signalling may incur no cost, or even reduce the incidence of predation, are common. Our results reveal unexpected complexity in a central viability cost to sexual signalling, while also speaking to applied problems in invasion biology and pest management where signal exploitation holds promise for bio-inspired solutions.

“…in an environment where potential mates are likely to be limited) are more likely to engage in risky behaviour (i.e. perform phonotaxis when the perceived risk of predation is high), especially if they have the opportunity to mate with a male with preferred song characteristics (Ghalichi et al, 2020). In G. lineaticeps, Beckers and Wagner (2011) have found some evidence that a female adopts different strategies for selecting a mate depending on male density at the time.…”

Acoustic communication is one of the most well-known behavioural traits of the Orthoptera. Orthopteran insects and the sounds they produce are both extremely diverse, and speciesspecific sounds are an extremely important tool in orthopteran taxonomy and systematics. For most species, acoustic signalling is the most important means of communication. It plays a vital role in mating, mate choice, intrasexual competition, interspecific interactions with predators and parasitoids, and the divergence of populations and species. The enormous diversity of the orthopterans has provided researchers with a wealth of model systems for studying anatomy, physiology, neurobiology, bioacoustics, communication, life-history traits, behaviour, evolutionary ecology, and speciation, all areas in which acoustic communication is important. We first reviewed orthopteran sound signalling nearly 20 years ago (Robinson and Hall, 2002), since when there has been an enormous amount of further work. This second review will look mainly at research published since that first review.
