Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …

There is mounting evidence that reduced genetic diversity in invasive populations is not as
commonplace as expected. Recent studies indicate that high propagule vectors, such as …

Invasive species are predicted to suffer from reductions in genetic diversity during founding
events, reducing adaptive potential. Integrating evidence from two literature reviews and two …

Mixed-ploidy species harbor a unique form of genomic and phenotypic variation that
influences ecological interactions, facilitates genetic divergence, and offers insights into the …

Introduced species often exhibit changes in genetic variation, population structure, selection
regime and phenotypic traits as they colonize and expand into new ranges. For these …

Recent biological invasions provide opportunities to investigate microevolution during
contemporary timescales. The tempo and scope of local adaptation will be determined by …

Much thought has been given to the individual‐level traits that may make a species a
successful colonizer. However, these traits have proven to be weak predictors of …

Aquatic plant invasions are often associated with long‐distance dispersal of vegetative
propagules and prolific clonal reproduction. These reproductive features combined with …

Human‐mediated species introductions offer opportunities to investigate when and how non‐
native species to adapt to novel environments, and whether evolution has the potential to …

Summary 1 Small and isolated populations of species are susceptible to loss of genetic
diversity, owing to random genetic drift and inbreeding. This loss of diversity may reduce the …
