“…Spooner & Ritchie, 2006). Although low mobility and possible colonization of high elevations only in the last millennium (Mahamoud-Issa et al, 2017), when interglacial climate warmed to its present conditions (Terral & Mengual, 1999), are two explanations for the absence of mixture, analysis of the genetic discontinuity on the Mediterranean coast offers a very different and more complete perspective.…”

“…Party et al, 2015;Greenfield et al, 2016). Laboratory studies showed that males and females from separate subclades, or even from clades 1 and 2, show little or no aversion to crossing, despite song and chorusing differences (Ritchie, 1996;Mahamoud-Issa et al, 2017). In some cases, males from another group are even preferred by local females.…”

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.

In the 21st century, phylogeography has experienced dramatic growth in the data and methods used by the field. Insect (more generally, hexapod) phylogeography has contributed to major advances and many of the influential papers included hexapods as model systems. In this literature review, we: (i) highlight recent phylogeographic work in hexapod systems, and (ii) identify broader trends and critical future steps in the field. We include a summary of useful methodological approaches and identify the methods used to approach different questions asked in phylogeographic studies. An updated summary of the applications that phylogeography has contributed to the field of entomology, including spatial studies, conservation, systematics, pest control, and invasive species, is included to highlight vital work in the field. Special attention is devoted to investigations which seek to use multi-species data to understand community ecological and evolutionary processes. Finally, we overview the main challenges, opportunities, and emerging areas, highlighting the “phylogeographic shortfall” that exists between the number of described hexapod species vs. the number of species that have been the focus of phylogeographic investigation.

The study of human language is progressively moving toward comparative and interactive frameworks, extending the concept of turn‐taking to animal communication. While such an endeavor will help us understand the interactive origins of language, any theoretical account for cross‐species turn‐taking should consider three key points. First, animal turn‐taking must incorporate biological studies on animal chorusing, namely how different species coordinate their signals over time. Second, while concepts employed in human communication and turn‐taking, such as intentionality, are still debated in animal behavior, lower level mechanisms with clear neurobiological bases can explain much of animal interactive behavior. Third, social behavior, interactivity, and cooperation can be orthogonal, and the alternation of animal signals need not be cooperative. Considering turn‐taking a subset of chorusing in the rhythmic dimension may avoid overinterpretation and enhance the comparability of future empirical work.
