TL;DR: The historical admixture zone within native North America originated before global invasion of this weed and could act as a potential source of introduced populations, providing evidence supporting the hypothesis that the invasive populations established through multiple introductions from the native range into Europe and subsequent bridgehead invasion into Australia.

TL;DR: The authors' data indicate rapid and repeated adaptation to local climates despite the recent introductions and a bottleneck limiting genetic variation in Australia, and suggest adaptation to more productive environments, potentially contributing to trait divergence between the ranges.

TL;DR: Hosts rejected their own eggs and manipulated (‘parasitic’) eggs above control levels in experiments when manipulated eggs were in the majority but when clutches also included a minority of own eggs, supporting a mechanism of template-based egg discrimination.

TL;DR: It is demonstrated that a species traditionally considered as part of the detrital (brown') food web is thus an important accelerator of vegetation succession, an important but often overlooked link in food web and ecosystem ecology.

TL;DR: Test repeatability in phenotypes and genotypes along parallel climatic clines within the native North American and introduced European and Australian Ambrosia artemisiifolia ranges reveals some predictability of evolutionary change during range expansion, key in a world facing ongoing climate change, and rapid invasive spread.
