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 …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …

Phylogeography, born to bridge population genetics and phylogenetics in an explicit
geographic context, has provided a successful platform for unveiling species evolutionary …

During the past decade there has been a tremendous resurgence of interest in polyploidy
that has in large part been stimulated by the development of increasingly powerful genetic …

Abstract Theory suggests that the evolution of autotetraploids within diploid populations will
be opposed by a minority-cytotype mating disadvantage. The role of triploids in promoting …

Baker's law refers to the tendency for species that establish on islands by long‐distance
dispersal to show an increased capacity for self‐fertilization because of the advantage of self …

Mating systems directly control the transmission of genes across generations, and
understanding the diversity and distribution of mating systems is central to understanding …

Two new polyploid species of Senecio have originated in the British Isles in recent times
following hybridization between native S. vulgaris (2 n= 40) and introduced S. squalidus (2 …
