Data from: Regular or covert sex defines two lineages and worldwide superclones within the leaf-curl plum aphid (Brachycaudus helichrysi, Kaltenbach)

Asexual reproduction occurs widely in plants and animals, particularly in insects. Aphid species usually reproduce by cyclic parthenogenesis, but many species include obligate asexual lineages. We recently showed that the leaf-curl plum aphid, Brachycaudus helichrysi, actually encompasses two lineages, B. helichrysi H1 and H2. Ecological data suggest that these lineages have different life cycles. We conducted a large population genetic study, based on 14 microsatellite loci, to infer their respective life cycles and investigate their...

Data from: ‘Becoming a species by becoming a pest’ or how two maize pests of the genus Ostrinia possibly evolved through parallel ecological speciation events

Denis Bourguet, Sergine Ponsard, Rejane Streiff, Serge Meusnier, Philippe Audiot, Jing Li & Zhen-Ying Wang
New agricultural pest species attacking introduced crops may evolve from pre-existing local herbivores by ecological speciation, thereby becoming a species by becoming a pest. We compare the evolutionary pathways by which two maize pests (the Asian and the European corn borers, ACB and ECB) in the genus Ostrinia (Lepidoptera, Crambidae) probably diverged from an ancestral species close to the current Adzuki bean borer (ABB). We typed larval Ostrinia populations collected on maize and dicotyledons across...

Data from: A new versatile primer set targeting a short fragment of the mitochondrial COI region for metabarcoding metazoan diversity: application for characterizing coral reef fish gut contents

Introduction: The PCR-based analysis of homologous genes has become one of the most powerful approaches for species detection and identification, particularly with the recent availability of Next Generation Sequencing platforms (NGS) making it possible to identify species composition from a broad range of environmental samples. Identifying species from these samples relies on the ability to match sequences with reference barcodes for taxonomic identification. Unfortunately, most studies of environmental samples have targeted ribosomal markers, despite the...

Data from: Rapid increase in dispersal during range expansion in the invasive ladybird Harmonia axyridis

Eric Lombaert, Arnaud Estoup, Benoît Facon, Benjamin Joubard, Jean-Claude Grégoire, Anaï Jannin, Aurélie Blin & Thomas Guillemaud
The evolutionary trajectories associated with demographic, genetic and spatial disequilibrium have become an issue of growing interest in population biology. Invasive species provide unique opportunities to explore the impact of recent range expansion on life-history traits, making it possible to test for a spatial arrangement of dispersal abilities along the expanding range, in particular. We carried out controlled experiments in laboratory conditions to test the hypothesis of an increase in dispersal capacity with range expansion...

Data from: Divergent evolutionary processes associated with colonization of offshore islands

Natália Martínková, Ross Barnett, Thomas Cucchi, Rahel Struchen, Marine Pascal, Michel Pascal, Martin C. Fischer, Thomas Higham, Selina Brace, Simon Y. W. Ho, Jean-Pierre Quéré, Paul O'Higgins, Laurent Excoffier, Gerald Heckel, A. Rus Hoelzel, Keith M. Dobney & Jeremy B. Searle
Oceanic islands have been a test ground for evolutionary theory, but here, we focus on the possibilities for evolutionary study created by offshore islands. These can be colonized through various means and by a wide range of species, including those with low dispersal capabilities. We use morphology, modern and ancient sequences of cytochrome b (cytb) and microsatellite genotypes to examine colonization history and evolutionary change associated with occupation of the Orkney archipelago by the common...
