Genome assembly of the ragweed leaf beetle, a step forward to better predict rapid evolution of a weed biocontrol agent to environmental novelties

Bouchemousse, Sarah ; Falquet, Laurent ; Müller-Schärer, Heinz

In: Genome Biology and Evolution, 2020, vol. 12, no. 7, p. 1167–1173

Rapid evolution of weed biological control agents (BCAs) to new biotic and abiotic conditions is poorly understood and so far only little considered both in pre-release and post-release studies, despite potential major negative or positive implications for risks of nontargeted attacks or for colonizing yet unsuitable habitats, respectively. Provision of genetic resources, such as assembled...

Rapid genomic and phenotypic change in response to climate warming in a widespread plant invader

Sun, Yan ; Bossdorf, Oliver ; Grados, Ramon D. ; Liao, Zhi, Yong ; Müller‐Schärer, Heinz

In: Global Change Biology, 2020//n/a/-

Predicting plant distributions under climate change is constrained by our limited understanding of potential rapid adaptive evolution. In an experimental evolution study with the invasive common ragweed (Ambrosia artemisiifolia L.) we subjected replicated populations of the same initial genetic composition to simulated climate warming. Pooled DNA sequencing of parental and offspring...

Assessing the risks of non-target feeding by the accidentally introduced ragweed leaf beetle, Ophraella communa, to native European plant species

Augustinus, Benno Andreas ; Gentili, Rodolfo ; Horvath, David ; Naderi, Ruhollah ; Sun, Yan ; Tournet, Anne-Marth Truce Eleonoor ; Schaffner, Urs ; Müller-Schärer, Heinz

In: Biological Control, 2020, vol. 150, p. 104356

In 2013, the North American oligophagous leaf beetle, Ophraella communa LeSage (Coleoptera: Chrysomelidae), was found in Europe for the first time. Recent studies in Northern Italy and Southern Switzerland record extensive defoliation by O. communa on its preferred host, common ragweed, Ambrosia artemisiifolia L. (Asteraceae, Tribe Heliantheae), and reductions in its flowering and seeding. In...

Scientists’ warning on invasive alien species

Pyšek, Petr ; Hulme, Philip E. ; Simberloff, Dan ; Bacher, Sven ; Blackburn, Tim M. ; Carlton, James T. ; Dawson, Wayne ; Essl, Franz ; Foxcroft, Llewellyn C. ; Genovesi, Piero ; Jeschke, Jonathan M. ; Kühn, Ingolf ; Liebhold, Andrew M. ; Mandrak, Nicholas E. ; Meyerson, Laura A. ; Pauchard, Aníbal ; Pergl, Jan ; Roy, Helen E. ; Seebens, Hanno ; Kleunen, Mark ; Vilà, Montserrat ; Wingfield, Michael J. ; Richardson, David M.

Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers of invasive alien species – the subset of alien species that spread widely in areas where they are not native, affecting the environment or human livelihoods – are increasing. Synergies with other global changes are exacerbating current invasions and...
