▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …

This paper considers key issues in plant invasion ecology, where findings published since
1990 have significantly improved our understanding of many aspects of invasions. The …

Polyploidy is a prominent process in plants and has been significant in the evolutionary
history of vertebrates and other eukaryotes. In plants, interdisciplinary approaches …

The origin of new homoploid species via hybridization is theoretically difficult because it
requires the development of reproductive isolation in sympatry. Nonetheless, this mode is …

In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in
Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and …

Polyploidy has played a major role in the evolution of many eukaryotes. Recent studies have
dramatically reshaped views of polyploid evolution, demonstrating that most polyploid …

Polyploidy has long been recognized as a prominent force shaping the evolution of
eukaryotes, especially flowering plants. New phenotypes often arise with polyploid formation …

summary The production of 2n gametes in plants, ie gametes with a somatic chromosome
number, is considered to be the dominant process involved in the origin of polyploid plants …

The study of hybrids and their evolutionary significance is often based on a number of tacit
assumptions regarding character expression in hybrids. This article examines …
