    The early wasp plucks the flower: disparate extant diversity of sawfly superfamilies (Hymenoptera:‘Symphyta’) may reflect asynchronous switching to angiosperm hosts2019In: Biological Journal of the Linnean Society, ISSN 0024-4066, E-ISSN 1095-8312, Vol. 128, no 1, p. 1-19Article in journal (Refereed)
    Abstract [en]

    The insect order Hymenoptera originated during the Permian nearly 300 Mya. Ancestrally herbivorous hymenopteran lineages today make up the paraphyletic suborder ‘Symphyta’, which encompasses c. 8200 species with very diverse host-plant associations. We use phylogeny-based statistical analyses to explore the drivers of diversity dynamics within the ‘Symphyta’, with a particular focus on the hypothesis that diversification of herbivorous insects has been driven by the explosive radiation of angiosperms during and after the Cretaceous. Our ancestral-state estimates reveal that the first symphytans fed on gymnosperms, and that shifts onto angiosperms and pteridophytes – and back – have occurred at different time intervals in different groups. Trait-dependent analyses indicate that average net diversification rates do not differ between symphytan lineages feeding on angiosperms, gymnosperms or pteridophytes, but trait-independent models show that the highest diversification rates are found in a few angiosperm-feeding lineages that may have been favoured by the radiations of their host taxa during the Cenozoic. Intriguingly, lineages-through-time plots show signs of an early Cretaceous mass extinction, with a recovery starting first in angiosperm-associated clades. Hence, the oft-invoked assumption of herbivore diversification driven by the rise of flowering plants may overlook a Cretaceous global turnover in insect herbivore communities during the rapid displacement of gymnosperm- and pteridophyte-dominated floras by angiosperms.

    Signature of post-glacial expansion and genetic structure at the northern range limit of the speckled wood butterfly2014In: Biological Journal of the Linnean Society, ISSN 0024-4066, E-ISSN 1095-8312, Vol. 113, no 1, p. 136-148Article in journal (Refereed)
    Abstract [en]

    The post-glacial recolonisation of northern Europe has left distinct signatures in the genomes of many organisms, both due to random demographic processes and divergent natural selection. However, information on differences in genetic variation in conjunction with patterns of local adaptations along latitudinal gradients is often lacking. In this study, we examine genetic diversity and population structure in the speckled wood butterfly Pararge aegeria in northern Europe to investigate the species post-glacial recolonisation history and discuss how this may have affected its life-history evolution. We collected 209 samples and analysed genetic variation in nine microsatellite loci. The results demonstrated a more pronounced population structure in northern Europe compared with populations further south, as well as an overall decrease in genetic diversity with latitude, likely due to founder effects during the recolonisation process. Coalescent simulations coupled with approximate Bayesian computation suggested that central Scandinavia was colonised from the south, rather than from the east. In contrast to further south, populations at the northern range margin are univoltine expressing only one generation per year. This suggests either that univoltinism evolved independently on each side of the Baltic Sea, or that bivoltinism evolved in the south after northern Europe was recolonised. © 2014 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 113, 136–148.

    How the leopard got its spots: a phylogenetic view of the evolution of felid coat patterns1997In: Biological Journal of the Linnean Society, ISSN 0024-4066, E-ISSN 1095-8312, Vol. 62, p. 383-400Article in journal (Refereed)
    Abstract [en]

    The current theory of felid coat pattern evolution proposes that the primitive pattern is one of relatively large spots that break down into smaller spots (here denoted flecks) and rosettes while at the same time leading to various striped patterns as sidelines. We have coded the coat patterns of felids into uniform, flecks, rosettes, vertical stripes, small blotches and blotches and show by mapping these character states onto phylogenies of the family that the current theory is flawed. Instead, the primitive pattern appears to be flecks and it is from this type that nearly all other types have developed. The robustness of this hypothesis is shown by the fact that it remains unchanged regardless of which of several quite different, competing phylogenies of the family is used. The pattern of transformations reconstructed is not predicted by current theories of pattern formation and we suggest that modellers pay closer attention to the phylogenetic histories of the features that they model.
