“…Several laboratory investigations of acoustic insect and anuran species have probed selective attention in choruses further. In a highly variable, alternating bushcricket species ( Ephippiger diurnus ) [46], playback of male calls from multiple loudspeakers that was adjusted to represent nearby and more distant neighbours showed that test males paid attention to fewer neighbours in populations where choruses typically had infrequent and brief silent gaps; gap frequency and length were largely determined by male call length and call repetition rate in the population [47]. As in many other acoustic insects and anurans, E. diurnus females prefer males that broadcast leading calls, and males adjust their relative call timing such that they avoid following a neighbour.…”

Animals communicating interactively with conspecifics often time their broadcasts to avoid overlapping interference, to emit leading, as opposed to following, signals or to synchronize their signalling rhythms. Each of these adjustments becomes more difficult as the number of interactants increases beyond a pair. Among acoustic species, insects and anurans generally deal with the problem of group signalling by means of ‘selective attention’ in which they focus on several close or conspicuous neighbours and ignore the rest. In these animals, where signalling and receiving are often dictated by sex, the process of selective attention in signallers may have a parallel counterpart in receivers, which also focus on close neighbours. In birds and mammals, local groups tend to be extended families or clans, and group signalling may entail complex timing mechanisms that allow for attention to all individuals. In general, the mechanisms that allow animals to communicate in groups appear to be fully interwoven with the basic process of rhythmic signalling. This article is part of the theme issue ‘Synchrony and rhythm interaction: from the brain to behavioural ecology’.

“…Prominent subclades exist within clades 1 and 2 and represent populations grouped within certain valleys: subclades in the Cerdagne valley in clade 1 and along the Ariège and upper Garonne rivers in clade 2. The main phenotypic differences between clades 1 and 2 are in the male calling song and chorusing and the female preferences for song (Party et al, 2014;Barbosa et al, 2016;Marin-Cudraz & Greenfield, 2016;Greenfield et al, 2017). Males in clade 1 populations produce calls with three or more syllables, whereas clade 2 populations have only one or two-syllable calls (cf.…”

We studied the Pleistocene diversification of a relatively endemic Mediterranean insect (Ephippiger diurnus; Orthoptera: Tettigoniidae) to understand how species with restricted range may nonetheless exhibit the complex phylogeography normally associated with broad distribution. A time-calibrated molecular phylogeny based on two mitochondrial genes showed that E. diurnus diverged into two major clades, distinguished largely by male song, before or early during the Pleistocene. Several subclades also diverged before the most recent glacial period. Data from 20 microsatellite loci indicated higher genetic diversity in populations along the Mediterranean coast in France, consistent with the hypothesis that glacial refuges were located there. 'Isolation by distance' accounts for much genetic differentiation between populations, but some adjacent populations are highly differentiated. A Bayesian approach defined genetically distinct clusters and assigned individuals to their most probable cluster. Clusters corresponded to clades in the phylogenetic tree, and we used cluster assignments to estimate interclade gene flow in areas of potential secondary contact. Gene flow is negligible in potential contact areas in the Pyrenees, but a narrow hybrid zone featuring a steep cline exists on the coast. This hybrid zone suggests that the major clades represent distinct species that diverged within a restricted area during the Pleistocene.
