It is shown that mode of pollination can confidently be predicted from fig traits only (anther–to–ovule ratio) or from wasp trait only (presence of coxal combs), and that active pollination remains the predominant mode ofpollination in Ficus.

The fig–wasp mutualism exhibits extraordinarily long–term evolutionary stability despite clearly identifiable conflicts of interest between the interactors, which is reflected by the very distinct variations found on the basic mutualistic theme.
An Extreme Case of Plant–Insect Codiversification: Figs and Fig-Pollinating Wasps
Biogeographic analyses indicate that the present-day distribution of fig and pollinator lineages is consistent with a Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance.
Inferring the origin of populations introduced from a genetically structured native range by approximate Bayesian computation: case study of the invasive ladybird Harmonia axyridis
The genetic structure of the invasive ladybird Harmonia axyridis in its native area was characterized using various population genetic statistics and methods and found that native area of H. axyrides most probably consisted of two geographically distinct genetic clusters located in eastern and western Asia.

Investigation of Ficus life-history trait evolution and fig/fig wasp coadaptation in the context of a well-resolved molecular phylogeny reveals correlations in ostiole shape, stigma morphology, and stamen:ovule ratio that provide evidence for reciprocal adaptations of morphological characters between these mutualistic partners that have interacted over a long evolutionary time.
One Fig to Bind Them All: Host Conservatism in a Fig Wasp Community Unraveled by Cospeciation Analyses Among Pollinating and Nonpollinating Fig Wasps
Cospeciation analyses between figs of section Galoglychia and some of their associated fig wasps show that, although host switches and duplication have evidently played a role in the construction of the current associations, the global picture is one of significant cospeciation throughout the evolution of these communities.

The diversity pattern of Arseno‐phonus strains in aphid populations from 86 species strongly suggests that ecological interactions, such as plant mediation and parasitism, are major drivers for Arsenophonus dispersal, dictating global incidence across insect communities.
Multiple nuclear genes stabilize the phylogenetic backbone of the genus Quercus
Using a dating approach, an Eocene age for the primary divergences in Quercus and a root age of about 50–55 Ma agrees with palaeobotanical evidence, indicating that morphological differentiation pre-dates genetic isolation in this clade.
Unravelling the historical biogeography and diversification dynamics of a highly diverse conifer‐feeding aphid genus
This hypothesis that the intercontinental disjunctions observed in the Holarctic for many aphid groups resulted from the disappearance or migration of their hosts is explored for the conifer‐feeding genus Cinara.
Fine-scale cospeciation between Brachycaudus and Buchnera aphidicola: bacterial genome helps define species and evolutionary relationships in aphids

This study highlights the usefulness of species delimitation methods in cospeciation studies involving species difficult to conceptualize—as is the case for bacteria—and in cases in which the taxonomy of the interacting organisms has not been determined independently and species definition depends on host association.
